The squat machine of claim 1, wherein the pulley (60) includes a contact part (610) contacting the connection wire, and wing parts (620) disposed on both sides of the contact part (610) and preventing shaking of the connection wire, and a distance between a rotation center of the pulley (60) and a center of the first axis (21) is greater than 1 time and less than 1.5 times a sum of a radius of each of the wing parts and a radius of the first axis.
  4. The squat machine of claim 1, wherein the third axis (41) of the handle member (40) moves with respect to the first axis (21) when the exercise member rotates with respect to the base frame, and a distance from the pulley (60) to the handle member (40) changes while the third axis (41) moves.
  5. The squat machine of claim 1, wherein the exercise member includes shoulder support portions (23) configured to contact user's shoulders, and the handle member (40) is disposed adjacent to each of the shoulder support portions.
  6. The squat machine of claim 5, wherein a shortest distance between the handle member (40) and each of the shoulder support portions is within 20 cm.
  7. The squat machine of claim 1, wherein the support member (30) is disposec lower than the exercise member when the support member is at the first position.
  8. The squat machine of claim 1, wherein the support member (30) includes a first support portion (321) supporting the exercise member at a first height, and a second support portion (322) supporting the exercise member at a second height lower than the first height.
  9. The squat machine of claim 1, wherein the support member (30) includes a safety stopper (323) supporting the exercise member to prevent the exercise member from directly contacting a floor at the second position.
  10. The squat machine of claim 1, wherein the support member (30) is configured to move from the first position to the second position by gravity.
  11. The squat machine of claim 10, wherein the support member further includes a weight portion (222) providing a load to move from the first position to the second position.
  12. The squat machine of claim 1, further comprising: a bias member (70) disposed on at least one end of the connection wire and providing a bias pulling the connection wire in one direction.
  13. The squat machine of claim 12, wherein the bias member includes a fixing portion (71) fixed to an end of the connection wire; a connection housing (72) connecting the connection wire to the support member or the handle member; and an elastic member (73) providing an elastic force to move the fixing portion away from the connection housing.

Description

Technical Field The present disclosure relates to a squat machine. Background Art In accordance with increased quality of life, the interest of people in health is increasing, and numerous people are using various forms of weight exercise equipment to improve their physical strength. Weight exercise equipment is provided in various forms according to the body part or purpose of use, to increase muscle strength. For example, in order to increase the muscle strength of the lower body of a user, there is a squat machine that allows the user to perform a squat exercise. A general squat exercise strengthens the strength of the lower body by the user repeatedly sitting down and standing up while lifting a barbell or a dumbbell. However, the squat exercise using a barbell or a dumbbell may cause injury when the user loses its center of gravity. In consideration of this point, recently, a squat machine capable of preventing injury of a user and having a practical squat exercise effect is being developed. The squat machine may include a base frame, an exercise member which is rotatable with respect to the base frame and capable of supporting a weight member, and a support member capable of moving and supporting the exercise member. US 2018/0104526 A1 discloses a squat exercise machine for performing squat exercise in a safe and controlled manner by providing shoulder pads with a specific angle which allows for the optimal comfort, posture, safety, and transfer of strength to a free weight squat. Support members are provided for more stability to the squat exercise machine. A stopping mechanism provides controlled movement by the user and a safe entry and exit from the squat exercise machine. Summary of the invention The scope of the invention is defined by the appended claims. Disclosure Technical problem The present disclosure provides a squat machine capable of easily manipulating a support member and minimizing the movement of the support member during an exercise, and a method of using the squat machine. Technical Solution According to an embodiment, a squat machine includes a base frame, an exercise member which is rotatable about a first axis with respect to the base frame and supportable at least one weight member, a support member which is rotatable about a second axis, which is different from the first axis, with respect to the base frame and rotates between a first position located on a rotation path of the exercise member at which the exercise member is supportable and a second position out of the rotation path of the exercise member, a handle member which is formed on the exercise member to rotate about a third axis, which is different from the first axis and the second axis, so that the support member is rotated to the first position, a connection wire connecting the support member to the handle member, and a pulley guiding movement of the connection wire. The pulley may be disposed on the base frame such that the support member is maintained at the second position when the exercise member rotates with respect to the base frame. Rotation of the handle member may be limited to within 20 % of a rotatable range when the exercise member rotates with respect to the base frame while the support member is located at the second position. The pulley may include a contact part contacting the connection wire and wing parts disposed on both sides of the contact part and preventing shaking of the connection wire, and a distance between a rotation center of the pulley and a center of the first axis may be greater than 1 time and less than 1.5 times a sum of a radius of each of the wing parts and a radius of the first axis. A length of the connection wire wound around the pulley may change when the exercise member rotates with respect to the base frame, and a position of the pulley with respect to the base frame may be determined in consideration of a change in the length of the connection wire wound around the pulley. The third axis of the handle member may move with respect to the first axis when the exercise member rotates with respect to the base frame, and a distance from the pulley to the handle member may change while the third axis moves. The exercise member may include shoulder support portions configured to contact user's shoulders, and the handle member may be disposed adjacent to each of the shoulder support portions. A shortest distance between the handle member and each of the shoulder support portions may be within 20 cm. The support member may be disposed lower than the exercise member when the support member is at the first position. The support member may include a first support portion supporting the exercise member at a first height and a second support portion supporting the exercise member at a second height lower than the first height. The support member may include a safety stopper supporting the exercise member to prevent the exercise member from directly contacting the floor at the second pos
