The surface layer of the handle 700 may be made of a soft and non-slippery material such as rubber. When a user takes in the handle 700, the bottom sheet 740 moves towards the sliding groove 720 under the action of the gripping force of the user, and then the power-on base 940 is driven to move in the direction departing from the mounting groove 730, and at the moment, the power-on base 940 is separated from the power-on contact 930; when the user's hand is disengaged from the handle 700, the energizing base 940 is moved toward the mounting base and contacts the energizing contact 930 by the resilient member 950.
Based on the above-mentioned electromagnetic control assembly, when the user holds the handle 700, the movement of the cross bar 400 is not affected by the electromagnet, so that the user can exercise normally; when the hand of the user is separated from the handle 700, the power-on base 940 is in contact with the power-on contact 930, the whole circuit is conducted, and the electromagnet and the metal rod form a strong adsorption force, so that the user is protected from severe collision. Of course, before the electromagnetic weight lifting exercise machine disclosed in this embodiment is used, the switch 910 needs to be turned on to protect the electromagnetic control assembly, and after the electromagnetic weight lifting exercise machine is used, the processing switch 910 is turned off.
In some embodiments of the present embodiment, the handle 700 is slidably connected to the cross bar 400, and the handle 700 is connected to the sliding rheostat 920 by a mechanical structure, so that when the handle 700 moves, the output resistance of the sliding rheostat 920 can be changed, thereby changing the current of the whole circuit, and further changing the magnitude of the attraction force between the electromagnet and the metal rod.
The handle 700 may be connected to a sliding sheet in the sliding rheostat 920, the handle 700 is connected to the cross bar 400 in a sliding manner, and the sliding rheostat 920 is fixedly connected to the cross bar 400, so that when the handle 700 moves relative to the cross bar 400, the sliding sheet of the sliding rheostat 920 can be driven to slide on the resistance wire, thereby changing the output resistance of the sliding rheostat 920. In this embodiment, the direction of the slide rheostat 920 is adjusted such that the resistance of the slide rheostat 920 becomes larger when the handle 700 is slid toward the corresponding stand 200, and the resistance of the slide rheostat 920 becomes smaller when the handle 700 is slid in a direction away from the corresponding stand 200. This is because when the handles 700 slide toward the corresponding stands 200, the distance between the two handles 700 increases, which indicates that the arms of the user are longer, and in the course of the training in a theater, even if the hands are separated from the handles 700, the crossbar 400 still has a larger buffer distance from the user on the bed 100, which can ensure the safety of the user; when the handles 700 slide in the direction away from the corresponding stand 200, the distance between the two handles 700 is reduced, which means that the user has a relatively short arm, and after the cross bar 400 is lifted, the descending buffer distance of the cross bar 400 is also short, and at this time, the resistance of the slide rheostat 920 is reduced, which can increase the current of the circuit, thereby enhancing the adsorption force between the electromagnet and the metal rod, and ensuring that the cross bar 400 can be stopped by the electromagnet more quickly.
In some embodiments of this embodiment, the handle 700 is further provided with a positioning structure 800 for fixing the handle 700 and the cross bar 400, so as to prevent the handle 700 from continuously sliding relative to the cross bar 400 when a user lifts a weight.

Both mounting portions 820 are mounted to the constraining tube 810, and the two mounting portions 820 are located at both sides of the opening 811, respectively. The slack adjusters 830 are connected to the two mounting portions 820, respectively, and the slack adjusters 830 are used to adjust the distance between the two mounting portions 820, thereby changing the width of the opening 811 and thus the diameter of the restraining tube 810.
Wherein, the tightness adjusting member 830 comprises a connecting rod 831 and a handle 832. The connecting rod 831 penetrates the two mounting portions 820 at the same time, and a nut is provided at a first end of the connecting rod 831.

When the handle 832 is rotated, the distance between the rotational axis of the handle 832 and the mounting portion 820 can be changed by using the protrusion 833. When the distance between the rotation axis of the handle 832 and the mounting part 820 is small, the opening 811 on the restraint tube 810 is large, and the pressing force of the restraint tube 810 on the cross bar 400 is small, so that the handle 700 can move relative to the cross bar 400; when the distance between the rotation axis of the handle 832 and the mounting portion 820 is large, the opening 811 on the restraint tube 810 is small, and the pressing force of the restraint tube 810 on the crossbar 400 is large, so that the handle 700 cannot move relative to the crossbar 400.
In this embodiment, a positioning groove is formed in one of the crossbar 400 and the constraining tube 810, the positioning groove extends along the length direction of the crossbar 400, and a latch for engaging with the positioning groove is formed in the other. The handle 700 can be prevented from rotating relative to the cross bar 400 by the cooperation of the fixture blocks and the positioning grooves, so that the handle 700 and the sliding rheostat 920 can be kept in normal cooperation, and when a user holds the handle 700, the handle 700 is stressed more from bottom to top, the power-on base 940 and the power-on contact 930 are guaranteed to be disconnected, extra resistance to the user is avoided, and normal exercise of the user is influenced.
