[0002] The compact spinning technology adds a fiber gathering device at the front end of the output roller of the original ring spinning machine to reduce the spinning triangle area, so as to reduce the hairiness of the yarn and improve the strength of the yarn. At present, the mainstream compact spinning devices in the world are mainly four-roller negative pressure type. The main parts of this device are designed with a special-shaped negative pressure pipe and an output roller. Ball bearings are installed at both ends of the output roller, and both ends of the output roller and the special-shaped negative pressure pipe are connected by engineering plastic or aluminum alloy structural parts. When the factory performs maintenance, it is necessary to disassemble the output roller and the special-shaped negative pressure pipe. Due to space limitations, conventional disassembly tools cannot be used, and workers use screwdrivers to knock on the structural parts at both ends for disassembly, often causing damage to the structural parts.

[0005] Optionally, a through hole is opened on the fixing plate, and the front end of the pushing cylinder is arranged in the through hole.

[0006] Optionally, the claw is connected to the fixing plate through a connecting member.

[0007] Optionally, the connecting member is an arc-shaped connecting plate.

[0008] Optionally, the opening of the arc-shaped connecting plate faces downward.

[0009] Optionally, a relief groove is opened upward at the bottom of the claw.

[0010] Optionally, the position of the relief groove corresponds to the position of the push rod.

[0011] Optionally, the relief groove includes an upper groove and a lower groove, and the size of the lower groove is larger than that of the upper groove.

[0012] Optionally, the position of the push rod corresponds to the position of the lower groove.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] A special tool for disassembling a compact spinning device of the present utility model can be used to disassemble the connecting structural members at both ends of the compact spinning device, avoid damage to the structural members, and improve work efficiency.
