[0023] In this embodiment, the lifting seat 6 is located between the two lifting slots 5 and is slidable up and down. The thread directions of the two ends of the outer periphery of the first adjusting rod 8 are oppositely arranged. The piston rod is lifted and lowered by the lifting seat 6, which facilitates the assembly of the piston rod and the cylinder.

[0024] In this embodiment, the first positioning block 9 is sleeved on the outer periphery of the first adjusting rod 8 and is threadedly connected. The two first positioning blocks 9 are symmetrically arranged with each other. The top end of the piston rod is clamped and fixed by the two first positioning blocks 9, which facilitates the removal and placement of the piston rod.

[0025] In this embodiment, the bottom end of the telescopic rod of the hydraulic pump 12 is fixedly installed between the top of the lifting seat 6, and the middle part of the lifting seat 6 is arranged in the same vertical line as the middle part of the base 1. The lifting seat 6 is raised and lowered by the extension and retraction of the telescopic rod in the hydraulic pump 12, so that the piston rod is inserted into the cylinder for automatic assembly.

[0026] In this embodiment, the positioning mechanism 4 includes two sleeves 13 and a second adjusting rod 14. The two sleeves 13 are movably installed on the inner sides of the two side panels 2 near the bottom end. A hinge 15 is connected and installed between the sleeves 13 and the side panels 2. Two second positioning blocks 16 are installed on the outer periphery of the second adjusting rod 14. Two guide rods 17 are installed on both sides of the two second positioning blocks 16 near the bottom end between the two side panels 2. Positioning grooves 18 are provided on the inner sides of the two second positioning blocks 16 near the front end. A second turntable 19 is fixedly installed at one end of the second adjusting rod 14.
