Through the transmission of the active bevel gear 11 and the driven bevel gear 12, the shaft 2 13 rotates, and the active gear 14 moves the rack 15, so that the placement frame 5 moves along the fixed frame 4, so that the placement frame 5 partially extends out of the shell 1, which is convenient for workers to take out the counterweight block body 6 in the placement frame 5. The limit plate 20 limits the moving distance of the placement frame 5. At this time, the worker places the counterweight block body 6 inside the placement frame 5 according to the required weight. The number of counterweight bodies 6 can be changed, and there is no need to prepare counterweights for replacement in advance. When the counterweight body 6 is inserted into the placement frame 5, the limit block 18 is inserted into the limit groove 16, so that the counterweight body 6 is connected to the placement frame 5, which plays a certain limiting role and improves the stability of the counterweight body 6 in the placement frame 5. When the counterweight body 6 is taken out from the placement frame 5, the counterweight body 6 is pulled to one side, the limit groove 16 squeezes the limit block 18, the limit spring 19 is compressed, and the limit block 18 is no longer connected to the limit groove 16. At this time, the counterweight body 6 is taken out.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
