[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.

At this time, the squeezed liquid will be smeared on the outer wall of the torsion spring, so that the torsion spring can be lubricated, reducing mechanical friction, thereby extending its service life.

[0014] 2. Through the designed disassembly assembly, the screws are rotated out from the inside of the connecting block to cancel the limit.

The outer wall of the rotating shaft 8 is movably sleeved with the torsion spring 9, and a storage cavity 16 is opened inside the rotating shaft 8. Sponges 17 are fixedly installed on the surfaces of both ends of the rotating shaft 8. A limiting plate 14 is fixedly installed on the bottom of the injection pipe 10, and a connecting pipe 12 is fixedly installed on the bottom of the limiting plate 14. A flow cavity 15 is opened inside the connecting pipe 12.

[0023] In this embodiment, when the rotating lubrication component is needed during operation, the lubricating liquid is first injected into the injection tube 10, and then transported into the rotating shaft 8 by the injection tube 10. At this time, it can be stored in the storage chamber 16, and the sponge 17 will absorb the lubricating liquid injected into the interior. During the deformation of the torsion spring 9, the outer wall of the sponge 17 will be squeezed, causing the sponge 17 to squeeze out the liquid inside. At this time, the squeezed liquid will be smeared on the outer wall of the torsion spring 9, so that the torsion spring 9 can be lubricated, reducing mechanical friction, thereby extending its service life.

At this time, one side of the telescopic rod 1 is opened to increase the height of the placement cavity 11. At this time, it is only necessary to pinch the outer wall of the rotating shaft 8 and pull it upward, so that the rotating shaft 8 can be disassembled and the torsion spring 9 sleeved on the surface can be replaced.
