The inner wall of the rotating shaft 13 is elastically connected to the pull rod a16 through the reset spring b15. One end of the reset spring b15 is fixedly connected to the end of the pull rod a16, and the other end of the reset spring b15 is fixedly connected to the inner wall of the rotating shaft 13. Pulling the pull rod a16 outward can stretch the reset spring b15 to move outward, and at the same time, the reset The elastic force generated by the deformation of the spring b15 gives the pull rod a16 a pulling force toward the inside of the rotating shaft 13, prompting it to reset. The inner wall of the pull rod a16 is fixedly connected with a locking assembly, which includes a limit block 17. The back of the limit block 17 is fixedly connected to the inner outer wall of the pull rod a16. The outer wall of the mounting plate 9 is provided with a plurality of groups of limit grooves 18.
