[0002] Existing clutch slave cylinders are all installed by transporting components separately. Some small components are easy to lose during transportation and are not easy to find. The installation position of the clutch slave cylinder is very limited. During installation, due to the small installation space, the installation difficulty increases, and parts such as pistons are likely to fall off. Because there are many other parts and pipelines at the installation position, it is not convenient to directly pick up the dropped parts, which is time-consuming and laborious. Summary of the Invention

One end of the connecting rod is connected to one end of the convex rod, and the other end of the connecting rod is connected to one end of the piston. A dust cover is connected to the connecting rod. One end of the dust cover is connected to the end of the connecting rod close to the convex rod, and the other end of the dust cover is connected to the pump body.

[0007] The middle of the pull belt is circular and a through hole is provided in the middle of the circle. The convex rod can pass through the through hole.

[0008] The pull belt is sleeved on the convex rod, and the surface of the pull belt close to the connecting rod contacts the connecting rod.

[0009] Both ends of the pull belt are in a T shape.

[0010] A clamping groove is provided on the pump body. Both ends of the pull belt can be connected in the clamping groove and the pull belt is in a tensioned state after connection.

[0011] One or more first grooves are provided on the pull belt and can be cut at the first grooves after installation is completed.

[0012] Further, a second groove is provided on the through hole.

[0013] Further, the piston is inside the pump body and can slide inside.

[0014] Further, a leather cup and a spring are connected to the piston.

[0015] Further, both sides of the pull belt are symmetrically arranged.

[0016] Further, one side of the pull belt close to the connecting rod is connected to one end of the dust cover.

[0017] Further, the other end of the dust cover is connected to the pump body.

[0018] Compared with the prior art, the present utility model has the following advantages:

[0019] By providing the pull belt, the piston is directly in the installation position, which not only is not easily lost during transportation, but can be directly installed in place through the pull belt during installation. Such a structure can directly simplify the installation and transportation of the clutch slave cylinder, facilitate the operation of the operator, shorten the installation time, and improve work efficiency.

[0030] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0031] AsFigure 1 , Figure 2 , Figure 3 As shown in Figure 3 , the push rod 1, the dust cover 2, the pump body 4, and the pull belt 3.

[0032] The push rod 1 includes a connecting rod 12 and a convex rod 11. The connecting rod 12 and the convex rod 11 are coaxial, and the diameter of the connecting rod 12 is larger than that of the convex rod 11. One end of the connecting rod 12 is connected to one end of the convex rod 11, and the other end of the connecting rod 12 is connected to one end of the piston 5. The dust cover 2 is connected to the connecting rod 12. One end of the dust cover 2 is connected to the end of the connecting rod 12 close to the convex rod 11, and the other end of the dust cover 2 is connected to the pump body 4.

[0033] The middle of the pull belt 3 is circular and a through hole 31 is provided in the middle of the circle. The convex rod 11 can pass through the through hole 31.

[0034] The pull belt 3 is sleeved on the convex rod 11, and the surface of the pull belt 3 close to the connecting rod 12 is in contact with the connecting rod 12.

[0035] Both ends of the pull belt 3 are in a T shape.

[0036] A clamping groove 41 is provided on the pump body 4. Both ends of the pull belt 3 can be connected in the clamping groove 41, and the pull belt 3 is in a tensioned state after being connected.

[0037] One or more first grooves 32 are provided on the pull belt 3 and can be cut at the first grooves 32 after installation is completed.

[0038] In this application, through the limitation of the pull belt 3, the lateral sliding of the push rod 1 and the piston 5 is restricted and will not slide out of the pump body 4. Such a setting can prevent the push rod 1, the piston 5, the leather cup 6, the spring 7, etc. from falling due to bumps during transportation, and also simplifies the installation steps. After the direct installation is completed, the pull belt 3 is cut, which shortens the time and improves the work efficiency.

[0039] As Figure 2 , Figure 3 shown, a second groove 311 is provided on the through hole 31.

[0040] In this application, providing the second groove 311 can increase the friction between the convex rod 11 and the pull belt 3, so that the pull belt 3 is not easily slipped off from the front end of the convex rod 11.

[0041] As Figure 1 shown, the piston 5 is inside the pump body 4 and can slide inside.

[0042] As Figure 1 shown, a leather cup 6 and a spring 7 are connected to the piston 5.

[0043] As Figure 2 , Figure 3 shown, both sides of the pull belt 3 are symmetrically arranged.

[0044] As Figure 1 shown, one side of the drawstring 3 close to the connecting rod 12 is connected to one end of the dust cover 2.

[0045] As Figure 1 shown, the other end of the dust cover 2 is connected to the pump body 4.

[0046] In this application, the spring 7 is provided to fix the piston 5. After the piston 5 is installed, it will be subjected to two forces that are opposite and equal on the same axis from the outside and the spring 7. The two sides of the drawstring 3 are symmetrically arranged, which can ensure the balanced pulling force of the drawstring 3 on the pump body 4, and the service life of the drawstring 3 is longer.

[0047] Finally, it should be noted that this embodiment is only used to illustrate the present invention and does not limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
