The other end of the belt 3 is slidably connected to the inner wall of the circular block 4, so that the belt 3 can connect the machine to the waist of the worker. The outer wall of the belt 3 is slidably connected with a pad A5, so that the worker can adjust the pad A5 to a comfortable position. The pad A5 is made of soft elastic material and can protect the back waist, reducing the pressure of the belt 3 on the back waist of the worker. The top of the circular block 4 is fixedly connected to the bottom of the hydraulic rod 2, so that the circular block 4 provides a supporting and fixing effect for the hydraulic rod 2 to maintain the stability of the machine during operation.

[0032] Reference Figure 2-Figure 4 The inner wall of the circular block 4 is rotatably connected with a round rod 9, and the outer wall of the round rod 9 is provided with a square block, so that the round rod 9 can rotate on the inner wall of the circular block 4, and the square block provided on the outer wall of the round rod 9 can rotate simultaneously with the rotation of the round rod 9. The outer wall of the round rod 9 is elastically connected to the inner wall of the circular block 4 through a spiral spring A10, one end of the spiral spring A10 is fixedly connected to the outer wall of the round rod 9, and the other end of the spiral spring A10 is fixedly connected to the inner wall of the circular block 4, so that the belt 3 is inserted into the circular block When sliding, the square block on the outer wall of the round rod 9 is inserted into the notch on the outer wall of the belt 3 by the elasticity of the spiral spring A10. After the round rod 9 and the belt 3 are rotated to release the fixation, the round rod 9 can be reset by the elasticity of the spiral spring A10. The inner wall of the U-shaped block 7 is slidably connected with a square rod 12, so that the square rod 12 can slide along the inner wall of the U-shaped block 7 in a fixed direction without deviation.
