Collar group is made up of the collar and retainer ring, and the collar is the assembly of ring-type, and the periphery engrail is combined with the brake block of braking group; Be provided with groove in collar outer rim, retainer ring is arranged in it; Offer in order to grip the collar opening of multiangular nut or bolt head at the collar one end, the collar is connected with body by retainer ring, and this retainer ring is provided with opening.

Wherein, braking group is arranged on the left and right sides of the junction of lever and projection.

The compression spring of the elastomer of wherein, braking group for forcing the brake block and the collar to fix mutually.

Wherein, body is concaved with a rotation hole that can cooperate ratchet tool to assemble.

Wherein, the distance of the angle outer end of two combination bore of body is greater than the distance of the width of opening.

Pass through said structure, the utility model can be used for dismantling multiangular nut or bolt head, implement in using, the rotating manner that utilizes ratchet can be comparatively laborsaving when the locking part by the spanner of open type, and when the application of force, be provided with the braking group because of junction at body lever and projection, can allow the point of application concentrate on the braking group, to avoid the spanner damage that crumbles, be one fully to meet the product of industry applications in fact.
