The utility model specifically adopts the following technical scheme for realizing the purpose:

the utility model provides a hexagonal axle sleeve, includes the fixed disk, the bottom surface demountable installation of fixed disk has the axle sleeve main part, be provided with four wallboards on the outer wall of axle sleeve main part, the both ends of wallboard all are fixed with the inserted block, the slot with inserted block looks adaptation is all seted up at the bottom surface of fixed disk and the top of axle sleeve main part, the bottom demountable installation of axle sleeve main part has the connection pad, the top of connection pad is fixed with the sleeve, the sleeve sets up in the axle sleeve main part.

Further, the fixed disk is connected with the shaft sleeve main body through a first bolt, threaded holes matched with the first bolt are formed in the top of the fixed disk and the top of the shaft sleeve main body, and the end portion of the first bolt is designed to be an inner hexagonal shape.

Further, the connection pad passes through the second bolt and is connected with the axle sleeve main part, the bottom of connection pad and the bottom of axle sleeve main part all offer the screw hole with second bolt looks adaptation, the tip of second bolt is the hexagon socket head design.

Further, the inner wall of the sleeve is coated with a wear resistant coating.

(III) advantageous effects

Compared with the prior art, the utility model provides a hexagonal shaft sleeve, which has the following beneficial effects:

according to the utility model, when a certain wall plate is damaged under the action of external force, the wall plate can be replaced, and when the inner wall of the sleeve is abraded with the shaft for a long time and cannot work normally, the sleeve can be replaced without replacing the whole wall plate, so that the use cost can be reduced.
