[0025] The pull rod structure includes a pull rod body 12, which is vertically arranged in the inner cavity of the fixing box 10 and can slide in the vertical direction. The top of the pull rod body 12 can be pulled out to the outside of the fixing box 10, and the bottom of the inner wall of the fixing box 10 is fixedly connected with a fixing plate 15.

[0026] A spring 18 is fixedly connected between the rear side of the fixing plate 15 and the front end of the clamping block 16 , and a pull rope 14 is fixedly connected to the bottom end of the pull rod body 12 . The other end of the pull rope 14 can be pulled through the fixing plate 15 and is fixedly connected to the front end of the clamping block 16 .
