Description

Arm exerciser Technical Field The present invention relates to an arm exerciser, and more particularly, to an arm exerciser including a pair of working arms and a gas spring, and capable of adjusting the strength of elastic force provided by the gas spring. Background Generally, an arm exerciser is an exercise machine for exercising muscle strength of arms, shoulders, and the like, and includes a head portion to which a spring is attached, and a pair of working arms operatively connected to the spring. The arm exerciser is moved by grasping the left and right arms with the hands of a user, applying force to bring the arms close to each other, applying muscle force to the arms, shoulders, etc., releasing the force to return the arms to the original separated position, relaxing the muscle force of the arms, shoulders, etc., and repeating the movement. However, the conventional arm exerciser has a disadvantage that the user cannot easily adjust the strength according to the muscle strength of the user. Disclosure of Invention Technical problem The invention aims to provide an arm strength device which can adjust the elastic strength provided by a gas spring when the arm strength moves, so that a user can adjust the strength according to the muscle strength of the user and perform the arm strength movement. Technical proposal In order to achieve the above object, the arm power exerciser according to the present invention includes a head portion, two working arms, and at least one gas spring, wherein upper ends of the two working arms are coupled to the head portion by a rotation shaft to perform an approaching and separating operation, the at least one gas spring is coupled between the two working arms such that a lower end thereof is rotatably coupled to one working arm and an upper end thereof is coupled to an upper side portion of the other working arm, a moving hole extending in a circular arc shape about the lower end of the gas spring is formed in an upper side portion of the working arm to which the upper end of the gas spring is coupled, the arm power exerciser includes a slider that supports the upper end of the gas spring so as to be movable along the moving hole, and the slider includes a stopper portion that is engaged in the moving hole to fix the upper end of the gas spring at an adjusted position. According to an embodiment of the present invention, a coupling tooth is formed on an inner side surface in a longitudinal direction in the moving hole, the stopper portion of the slider is provided with an engaging tooth engaged with the coupling tooth, and the stopper portion is movable between an engaged position in which the engaging tooth is engaged with the coupling tooth to fix the slider at the adjusted position and a released position in which the engaging tooth is disengaged from the coupling tooth to allow the slider to move. According to an embodiment of the present invention, tooth-shaped portions are formed on outer peripheral surfaces of respective upper end portions of the two working arms, the tooth-shaped portions being engaged with each other so that the two working arms are rotatably coupled to the head portion. According to an embodiment of the present invention, the gas spring includes two gas springs, and the two gas springs are disposed at the front and rear surfaces of the two working arms in a staggered manner. According to an embodiment of the present invention, the slider includes a slider body including a first body and a second body which are disposed on both side surfaces of the working arm via the movement hole and are coupled to each other, and the coupling shaft of the upper end of the gas spring is coupled to the first body, the stopper portion has a shaft shape which is supported between the first body and the second body so as to be movable, the engagement teeth are formed to protrude from an axial intermediate portion of the stopper portion, and the engagement teeth are disposed in the movement hole at the engagement position or are disengaged to the outside of the movement hole so as to be disposed at the release position by the movement of the stopper portion in an axial direction intersecting the movement hole. According to an embodiment of the present invention, the arm power exerciser includes a support spring that pressurizes the limit portion toward the engagement position so as to maintain the engagement teeth of the limit portion in the engagement position engaged with the engaging teeth in the moving hole. According to the embodiment of the invention, the accommodating groove is formed on the inner side surface of the first main body, the accommodating groove is used for accommodating the engaging teeth of the limiting part to form the release position, and when the limiting part is pressed, the limiting part moves along the axial direction while compressing the supporting spring, so that the engaging teeth are accommodated in the accommodating groove.
