Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-5, the present utility model provides a technical solution: a clutch sealing bush comprises a sealing bush 3 which is positioned in a mounting sleeve 1 and positioned outside a transmission input shaft 2, wherein the sealing bush 3 comprises a bush body 301 and a gasket 302 positioned at the top of the bush body 301;

The top of the outer wall of the gasket 302 is provided with a plurality of outer clamping grooves 3001 which are distributed in an annular array by taking the center of the gasket 302 as the array center, when the sealing lining 3 is broken and broken, the outer clamping grooves 3001 and the inner clamping grooves 3002 which are arranged at corresponding positions can also be used for extracting the separated sealing lining 3, the position of the top of the inner wall of the gasket 302 corresponding to the outer clamping grooves 3001 is provided with an inner clamping groove 3002, the inner clamping groove 3002 is a trapezoid groove with large opening size at one side close to the inner wall of the gasket 302 and small opening size at one side far away from the inner wall of the gasket 302, the inner clamping groove 3002 is matched with the clamping part of a clamping tool, so that the clamping part can enter the anti-slip groove 3003 faster, the opening size of the inner clamping groove 3002 at one side far away from the gasket 302 is the same as that of the anti-slip groove 3002, the clamping part of the clamping tool is ensured to enter the anti-slip groove 3003, the top of the inner clamping groove 3002 is opened, and only one side corresponding to the inner clamping groove 3002 is opened;
