DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-4 A adjustable hydraulic clutch cylinder includes a cylinder body 1 and an oiling nozzle 2 located on its side wall and connected to the cylinder body 1. The two ends of the cylinder body 1 are respectively threadedly connected with a rear end cover 7 and a front end cover 8. The end of the front end cover 8 is provided with a threaded tube 3, and the threaded tube 3 is provided with a mounting structure a. A rod body 9 is slidably provided on the front end cover 8. The front end of the rod body 9 is provided with a threaded head 5, and the threaded head 5 is provided with a mounting structure b.
