Abstract

The utility model discloses an eagle claw rotary tool, comprising a knife handle, a knife body and a convex body which is arranged on the knife body and is used for blocking off a blocking ring. Two blocking rings are sheathed on the knife body, a pressure spring is arranged between two blocking rings, and two spring sheets penetrate the pressure spring and the blocking ring and is fixed on the blocking ring at the back side; the endpoint of the eagle claw-shaped spring sheet forms an outward splayed shape. The utility model has the advantage of convenient use, and when a screw is screwed, the screw is held without hands to stabilize the screw.

Description

Spinner

The utility model discloses a kind of screwdriver, specifically a kind of screwdriver of handling by turning handle.

Now Chang Yong screwdriver has two kinds, a kind of cutter hub fore-end of screwdriver is a pancake, the cutter hub front end face of another kind of screwdriver becomes the cross flute profile, and these two kinds of screwdrivers are difficult for holding screw when screwing screw, must make troubles to work with another hand steered firmly screw.

The purpose of this utility model provides a kind of Shi Buxu of screwing with the hand steered screw of living, and can hold the Spinner of screw.

The technical solution of the utility model is: Spinner comprises handle of a knife, be contained in the convex body that is used for blocking back-up ring is arranged on the cutter hub on the handle of a knife, two shield ring sleeves are contained on the cutter hub, be sleeved on stage clip on the cutter hub between two back-up rings, the rear end of passing two claws of a hawk type reeds of back-up ring, stage clip is fixed on the back-up ring of back symmetrically, and the top of claws of a hawk type reed becomes outer splayed configuration.

Convex body on the cutter hub can be the projection of cutter hub front end greater than the back-up ring inner ring diameter itself, also can be the half-turn that is fixed on the cutter hub, also can be to be fixed on the same contour of cutter hub two with upper protruding block around cutter hub; Convex body is positioned at the outside of back-up ring.

The utility model operation principle is, when screwing screw, through before pushing away when the back-up ring outside (convex body in front), impel claws of a hawk type reed to open the folder screw back-up ring of back, unclamp the power of push and block circle then, stage clip resets ring washer, at this moment claws of a hawk type reed is screws clamp, when screw threads near fastener the time, because claws of a hawk type reed top becomes outer splayed configuration, can be adjacent to fastener and open gradually with screw, be convenient to screw.

The utility model has the advantages that: increased claws of a hawk type reed and accessory thereof on the tool owing to adopted revolving, make the utility model modern design, can clamp screw by the reed pawl, place to hand steered inconvenience, deep hole reaches under charged situation, all can conveniently use, and simple in structure, small investment is convenient to promote.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Accompanying drawing 1: the utility model embodiment 1 structural representation.

Accompanying drawing 2: the utility model embodiment 2 structural representations.

Embodiment 1 is with reference to accompanying drawing 1, Spinner comprises that a front part has the cutter hub 2 of convex body 7, the lateral length of convex body 7 is greater than the interior diameter of back-up ring 3, back-up ring 3, stage clip 5, back-up ring 4 are enclosed within on the cutter hub from the rear end of cutter hub 2 successively, two reeds 6 making claws of a hawk type pass back-up ring 3, stage clip 5, back-up ring 4 and utilize the groove of reed end or rivet or welding to be fixed on symmetrically on the back-up ring 4, load onto handle of a knife 1 then.

Embodiment 2:

With reference to accompanying drawing 2, the front end of the cutter hub 2 of Spinner is flat, and has enation to constitute the convex body that stops back-up ring 3, and (being the version of Flathead screwdriver) all the other are with embodiment 1.

Implement 3:

Convex body on the cutter hub 2 described in the embodiment 1 can be fixed on the outside (back) of back-up ring 4, and when dress back-up ring 3, stage clip 5, back-up ring 4, from the front end sleeve of cutter hub 2, all the other are with embodiment 1.
