## Abstract

A bearing adjuster is comprised of a grip, an adjusting member, a fixing member and three movable members. The adjusting member is disposed on a protrusion of the grip. The fixing member is disposed on the adjusting member. The movable members are disposed on the fixing member correspondingly. A threaded rod of the grip is screwed in a threaded hole of a positioning protrusion of the fixing member. A sliding block of each movable member and positioning guide blocks of the sliding block are disposed in one of sliding grooves of the fixing member and positioning guide grooves of the sliding groove respectively. A guide protrusion of the movable member is disposed in one of corresponding grooves of the adjusting member. Thus, the bearing adjuster is able to adjust its' diameter to coordinate with different sizes of the bearings.

## Claims

### Claim 1

A bearing adjuster is comprised of:
a grip having an end provided with a pounding portion and the other end provided with a protrusion, wherein a positioning annular groove is formed around the protrusion, and a threaded rod is disposed at a front end of the protrusion;
an adjusting member disposed on the protrusion of the grip wherein a connecting protrusion is disposed on a side of the adjusting member, a perforation is formed in the connecting protrusion, a positioning threaded hole is formed in a wall surface of the connecting protrusion to pass through the perforation, a positioning fastener is screwed in the positioning threaded hole of the adjusting member, an internal end of the positioning fastener abuts within the positioning annular groove of the grip, and three corresponding grooves in the form of an arc extending outwards from the center are bored on the outside of the perforation on the other side of the adjusting member;
a fixing member disposed on the adjusting member, wherein a positioning protrusion is disposed on a side of the fixing member, a joint threaded hole is formed in the positioning protrusion, the threaded rod of the grip is screwed in the joint threaded hole of the positioning protrusion, an annular groove is formed on an outer wall surface of the positioning protrusion, a washer is disposed on the circular groove, three sliding grooves are bored on the fixing member equally, and positioning guide grooves opposite to each other are bored on both sides of the sliding grooves; and
three movable members disposed on the fixing member correspondingly, wherein a sliding block on a side of each of the three movable members, positioning guide blocks are protruded at two side edges of the sliding block, the sliding block is disposed in one of the sliding grooves of the fixing member, the positioning guide blocks are disposed in the positioning guide grooves of the sliding groove, a guide protrusion is disposed on surface of the sliding block, the guide protrusion is disposed in one of the corresponding grooves of the adjusting member, the movable member is provided with a plurality of stepped abutting portions, and an external surface of each of the abutting portions is bored with an abutting edge.

### Claim 2 (depends on 1)
