Description

Action demonstration teaching aid for flexible foundation teaching and application method thereof Technical Field The invention relates to the field of flexible foundation teaching demonstration teaching aids, in particular to an action demonstration teaching aid for flexible foundation teaching and a use method thereof. Background In teaching dance, cheering, aerobics, etc., it is important to grasp standard motion gestures by students and to demonstrate and explain standard basic motions. When a teacher develops leg pressing teaching, the teacher usually directly carries out action demonstration by means of the existing leg pressing bars, leg pressing actions are divided into multiple types, and teaching explanation needs to be demonstrated one by matching with corresponding actions for standardization and intuitiveness of basic action teaching. The teacher keeps various leg pressing demonstration postures for a long time and is easy to cause leg ache, particularly, the teacher is usually older than the student, the self endurance and flexibility are already in a sliding-down stage, and after continuously demonstrating a plurality of actions, the teacher is difficult to interrupt or end the demonstration and take a bar-down action. Disclosure of Invention The invention provides a motion demonstration teaching aid for flexible basic teaching and a use method thereof, which aim at solving the problem that in the prior art, a teacher is difficult to perform a down-bar motion after demonstrating the motion, and can reduce the difficulty of performing the down-bar motion after demonstrating the motion. To achieve the above object, in a first aspect, the present invention provides an action demonstration teaching aid for flexible basic teaching, comprising: A cross bar; The sliding device comprises an inclined surface sliding table and a foot fixing assembly, wherein the inclined surface sliding table is connected to the cross rod, the inclined surface sliding table comprises an upper surface deviating from the cross rod, one side of the upper surface along the extending direction of the cross rod is gradually far away from the cross rod from the other side, the foot fixing assembly comprises a first sub-portion and a second sub-portion, the first sub-portion is connected to the upper surface in a sliding mode along the extending direction of the inclined surface sliding table, the second sub-portion is hinged to the first sub-portion, the axial direction of a hinge shaft is an acute angle or a right angle with the extending direction of the cross rod, the second sub-portion is closer to the cross rod than the first sub-portion, one side of the second sub-portion, close to the upper surface, is detachably abutted to the upper surface, one side of the foot fixing assembly deviating from the cross rod is recessed towards the cross rod to form a foot fixing groove, the foot fixing groove extends along the width direction, and the foot fixing groove is partially located on the first sub-portion and the other foot fixing groove is located on the second sub-portion. When the action demonstration is started, the foot fixing assembly is required to slide to the position between the two sides of the upper surface or away from one side of the cross rod, a user lifts the legs to place the feet in the foot fixing grooves for the action demonstration, and the foot fixing grooves provide support for the lateral directions of the feet of the user, so that the user can conveniently and completely demonstrate the action. When the lower lever action is required, the foot fixing assembly slides towards one side close to the cross rod until the second sub-part at least partially exceeds the upper surface, the upper surface is an inclined surface, so that the difficulty of the lower lever is primarily reduced because the leg lifting amplitude of a user is reduced in the process that the second sub-part reaches the position, and after the second sub-part at least partially exceeds the upper surface, the upper surface can not provide support for the second sub-part, the second sub-part can rotate towards the cross rod, the foot fixing groove is opened towards one side of the second sub-part, and the user can transversely move the leg to finish the lower lever without lifting the leg again, so that the difficulty of the lower lever is further reduced. The sliding device further comprises a driving assembly, the driving assembly comprises a transmission piece and a driving piece, the transmission piece is arranged inside the inclined sliding table along the extending direction of the upper surface, the first sub-portion is connected with the transmission piece, the driving piece is connected with the transmission piece, and the driving piece is used for driving the first sub-portion to slide through the transmission piece. The driving component can drive the foot fixing component to move, so that convenience in use of the action demons
