Furthermore, a bottom cover is arranged at the bottom of the second balancing weight, a stroke cavity which is communicated with the bottom is arranged in the bottom cover, the second spring and the moving block are arranged in the stroke cavity, two ends of the second spring are respectively connected with the moving block and the top wall in the stroke cavity, and a connecting column which penetrates through the stroke cavity and is connected with the second blocking block is arranged at the top of the moving block.

Furthermore, a second guide groove corresponding to the positioning hole is formed in the top of the second balancing weight, a third guide groove corresponding to the positioning hole is formed in the top of the first balancing weight, and a guide channel for inserting the plug pin is formed between the first guide groove and the third guide groove and between the first guide groove and the second guide groove in a laminating mode.

Furthermore, the upper end surface and the lower end surface of the first balancing weight are respectively provided with a plurality of first positioning columns and positioning grooves which correspond to each other, and the upper end surface of the second balancing weight is provided with a plurality of second positioning columns which correspond to the positioning grooves.

Furthermore, first balancing weight with second balancing weight lateral wall is provided with the second spacing groove of mutual correspondence, the second spacing groove superposes in proper order and forms the back taper, be provided with in the installation cavity with the toper stopper that the spacing groove of back taper corresponds.

Furthermore, two ends of the positioning hole on one side are communicated with the mounting cavity and the outside, one end of the positioning hole on the other side is closed, and the other end of the positioning hole is communicated with the mounting cavity.

Further, the bolt includes a magnetic part and a hand-held piece that set up at the tip, be provided with in the casing and be used for adsorbing the magnetic module of magnetic part, when the magnetic part with the casing actuation, the bolt is fixed.

Furthermore, a containing cavity for installing the limiting assembly is arranged in the first guide groove, a butting block which is abutted against the first balancing weight or the second balancing weight on the lower layer is arranged at the bottom of the first check block, and two ends of the first spring are respectively connected with the top surface in the containing cavity and the top of the first check block.
