[0007] As preferred, the bottom center of the press head is provided with a boss, and the boss cooperates with the corresponding center hole of the CVT auxiliary cylinder main shaft end. The main shaft will not be offset in the radial position when pressed.

[0008] As preferred, the screw nut, screw nut and screw bolt are respectively provided with the same size of outer hexagonal screw. It is convenient to screw through the same tool.

[0009] As preferred, the adjusting hole is a waist round hole arranged transversely left and right.

[0010] As preferred, the limit pull rod is provided with a hand holding part. It is convenient to hold when the semicircular clamp is sleeved.

[0011] Preferably, the bottom of the limit rod is provided with a connecting screw, and the semicircular clamp is provided with a corresponding mounting hole. The connecting screw at the bottom of the limit rod passes through the mounting hole and is tightened with a nut to secure the semicircular clamp. The limit rod can be replaced with different lengths according to the product size to adapt to products with a variety of spacing.

[0012] The beneficial effects of the present invention are as follows: the present invention designs a CVT auxiliary cylinder disassembly tool, which is specially used for disassembling and assembling the auxiliary pressure cylinder assembly in the CVT, achieving surface non-damage disassembly and assembly, and convenient and quick disassembly and assembly, thereby greatly improving disassembly and assembly efficiency.

[0018] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0019] Example: Figure 2 As shown, a CVT auxiliary cylinder disassembly tool includes a base plate, and adjustment holes 9 for adjusting the position to the left and right are opened on both sides of the base plate 8 respectively. Limiting rods 12 are respectively passed through the two adjusting holes, and the upper ends of the two limiting rods are screws 13, and the screws are threadedly connected with screw nuts 14. Semicircular clamps 16 are respectively fixedly connected to the bottoms of the two limiting rods, and the two semicircular clamps are connected by screw bolts 17 to form a whole circular clamp. The inner diameter of the clamp matches the outer diameter of the CVT auxiliary cylinder sleeve. A pressing screw 10 is threadedly connected to the center of the base plate, and a screw nut 11 is fixedly installed on the upper end of the pressing screw, and a pressing head is fixedly installed on the lower end. The pressing head corresponds to the upper end of the CVT auxiliary cylinder main shaft.
