frame when external force is applied, after a user loosens the switch, the electromagnet is powered off, the T-shaped frame is pulled back by the tension spring, the teeth are meshed with the rack, the guide cross frame cannot move downwards along the guide vertical frame at the moment, the cross slide frame is arranged on the barbell rod in a penetrating way, the positioning pin on the cross slide frame is inserted into the positioning hole on the barbell rod under the tension of the reset spring, so that the fixing of the cross slide frame and the barbell rod is realized, when the cross slide frame is required to be separated from the barbell rod, the positioning pin, the cross slide frame can slide out of the barbell bar, the cross slide frame is in sliding fit with the cross groove on the guide cross frame through the step, the step is inserted into the cross groove, the cross slide frame cannot pass through the cross groove, and a cross guide wheel on the step is in rolling contact with the cross groove, so that the two cross slide frames which are oppositely arranged have a limiting function, the position of the barbell bar and the position of the guide cross frame are fixed, the barbell bar cannot axially move under the limitation of the cross slide frame on the guide cross frame, after the initial height of the barbell bar is set through the lifting oil cylinder, a user holds a handheld sleeve on the barbell bar in a training posture and presses a switch, the guide cross frame loses the limitation of a T-shaped frame, the user can lift or carry the barbell bar for strength training, the barbell bar can slide in the cross groove on the guide cross frame, and the design enables the user to have room for adjusting the posture forwards and backwards during action, the force can be exerted conveniently, when a user can not lift up or can not move the barbell bar after releasing the force, the user can immediately loosen the hand to loosen the switch, so that the electromagnet is demagnetized, the T-shaped frame returns to the position under the action of the tension spring, the teeth are meshed with the rack, the guide transverse frame is supported and cannot fall on the guide vertical frame, the user can immediately take off the body and cannot be pressed or injured by pounding by the barbell bar, and the independent training is also safe and reliable.
