The locking sleeve hydraulic cylinder is mainly composed of a cylinder barrel, a piston rod, a locking sleeve, a front cover, and a rear cover. The front cover and the rear cover are designed with a threaded structure, which cooperates with the front and rear threads of the cylinder barrel to assemble together. However, there is no force point for tightening tools on the front cover and the rear cover. There are only two light holes or threaded hole structures as force points during assembly. Currently, it can only be assembled by knocking. During batch assembly and after-sales service disassembly and assembly, there are no special tools for the front cover, rear cover and other components of the locking sleeve hydraulic cylinder. Some violent knocking and other means often cause damage to the parts, and the assembly quality cannot guarantee consistency. During after-sales service, the customer's on-site conditions are relatively poor, and the excess materials produced by violent knocking can easily enter the product, affecting the product life.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Please also read Figure 1 , Figure 2 , Fig.10 and Fig.11, a specific embodiment of an assembly tool for installing an end cover provided by the present invention is now described. The assembly tool for installing an end cover includes a first connecting component 1, a second connecting component 2, and a fixing rod 3, wherein the first connecting component 1 includes a first connecting rod 11 and a second connecting rod 12 hinged to the first connecting rod 11, the first connecting rod 11 includes a handle portion 111 and a connecting rod portion 112 integrally formed with the handle portion 111, one end of the second connecting rod 12 is arranged between the handle portion 111 and the connecting rod portion 112, and the angle between the connecting rod portion 112 and the second connecting rod 12 is adjustable; the second connecting component 2 is connected to the first connecting component 1 and has the same structure as the first connecting component 1, and the first connecting component 1 and the second connecting component 2 are centrally symmetrically arranged; the fixing rod 3 is rotatably connected to the first connecting component 1 and the second connecting component 2 at the same time, and is used to connect to the part 8 to be disassembled.

[0051] The assembly tool for end cover installation is used to install the end cover. The specific steps are: connect the two fixing rods 3 to the two force application holes on the end cover respectively, at which time the first connecting rod 11 and the second connecting rod 12 are in a relatively static state; apply force to the handle 111, and rotate the first connecting rod 11 to screw the end cover in and out to tighten or loosen the parts. This method can be used for the disassembly and assembly of the locking sleeve hydraulic cylinder end cover, and can replace the assembly and disassembly work completed by knocking and other methods.

[0052] In this embodiment, the handle portion 111 can be a straight rod-shaped structure, and its main function is to provide a force arm. The operator applies force from the outer edge of the handle portion 111 to tighten, or a sleeve tool can be added to extend the length of the handle portion 111 to assist in tightening. The function of the second connecting rod 12 is to connect the first connecting rod 11 in the first connecting assembly 1 and the first connecting rod 11 in the second connecting assembly 2, and acts as a two-force rod. The function of the fixed rod 3 is to be inserted into the force-applying structure of the end cap, and plays the role of positioning and transmitting the tightening force. The connecting rod portion 112 is an arc-shaped structure protruding to one side of the handle portion 111, and the second connecting rod 12 is an arc-shaped structure protruding to the other side of the handle portion 111, that is, the connecting rod portion 112 and the second connecting rod 12 are both arc-shaped structures protruding away from each other.
