[0023] The cooling mechanism 3 includes a connecting tube 301, and flowing cold water is injected into the liquid storage tube 303 through the injection port 305. The threaded strip 304 controls the water to have a spiral flow effect, so that the water absorbs the heat of the connecting tube 301, thereby achieving the effect of cooling the connecting tube 301. The inner wall of the connecting tube 301 fits with the hydraulic cylinder body 1, and the outer wall of the connecting tube 301 is fixedly connected with the rubber sealing ring 302. The outer wall of the rubber sealing ring 302 is threadedly connected with the liquid storage tube 303. The inner wall of the liquid storage tube 303 is fixedly connected with the threaded strip 304.

[0024] The injection port 305 injects flowing cold water into the liquid storage cylinder 303, and the threaded strip 304 controls the water to have a spiral flow effect, so that the water absorbs the heat of the connecting cylinder 301. The surface of the connecting cylinder 301 is covered with circular grooves 8 to increase the heat dissipation area, so that the heat generated by the hydraulic cylinder body 1 absorbed by the inner wall of the connecting cylinder 301 is quickly absorbed by the flowing water and cooled, thereby improving work efficiency and enabling long-term use.

[0025] The inner wall of the connecting cylinder 301 is provided with a circular groove 8, the outer wall of the liquid storage cylinder 303 is threadedly connected to the lower connecting seat 6, the mounting mechanism 4 includes a threaded ring 401, after the threaded ring 401 is mounted on the hydraulic oil cylinder body 1, the threaded ring 401 and the fixing seat 402 are assembled again, the fixing seat 402 is threadedly connected to the hydraulic oil cylinder body 1 of the threaded ring 401, the inner wall of the threaded ring 401 is threadedly connected to the fixing seat 402, and the inner wall of the fixing seat 402 is threadedly connected to the fixing screw 403
