Abstract
The utility model discloses a ratchet wheel socket spanner, which comprises a spanner body and a sleeve. The spanner body comprises a spanner and a spanner head arranged at one end of the spanner, wherein the spanner head is provided with a ratchet wheel groove, a spring ring and a ratchet wheel ring are positioned in the ratchet wheel groove, the ratchet wheel ring abuts against a matched toothed block, a circle of groove is positioned on the inner wall of the ratchet wheel ring, a ratchet wheel spring ring is positioned in the groove, an inner circle of the ratchet wheel ring is in a polygon shape, and an inner circle of the sleeve is provided with a regular-polygon-shaped sleeve hole. An outer circle of the sleeve is arranged in a polygon shape matched with the inner circle of the of the ratchet wheel ring, and the sleeve is positioned in the inner circle of the ratchet wheel ring and then is sleeved on a bolt through the regular-polygon-shaped sleeve hole of the inner circle of the sleeve. When the bolt is wrenched, the sleeve is labor-saving and convenient to wrench due to the fact that the whole sleeve is installed in the inner circle of the ratchet wheel ring, namely the spanner head is directly sleeved on the bolt. The ratchet wheel socket spanner can be applied to bolts in small areas.
Description
Technical field
The utility model relates to a kind of spanner.
Background technology
Existing box spanner generally all is at spanner one square tenon to be set partly, on tenon, puts the sleeve of different model then, and sleeve one end is and the square groove of tenon coupling that the other end is a hex shaped groove.Jacket casing on tenon after, sleeve is inserted on hex(agonal)screw or the bolt and is pulled again.This box spanner is in differing heights owing to transmission body with by the strength transmission between the transmission body when in use, and the stressed effect of screw or bolt is bad; Because the existence of tenon makes that the height at spanner position is higher, for narrow and small zone, some spaces, this spanner is just powerless simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of convenience, labour-saving box socket set pulled, and the bolt regional for small space can use.
Technical scheme below the utility model adopts: a kind of box socket set, comprise wrench body and sleeve, wrench body comprises pulls body, is arranged on the spanner of pulling body one end; Spanner is provided with ratchet slot; Be provided with turn and ratchet ring in the ratchet slot, ratchet ring has a circle groove against tooth piece with matching on the ratchet ring inwall; The ratchet spring circle is set in the groove; The ratchet ring inner ring is regular polygon, and said sleeve outer ring is the regular polygon that is complementary with the ratchet ring inner ring, and the sleeve inner ring is offered the trepanning that is regular polygon.
Described pulling extended an articulated section on the body, an articulated joint is set on the spanner, and be hinged through screw between articulated joint and the articulated section.Spanner is hinged on to be pulled on the body, and the rotation that spanner can easy on and off has further increased the working region and the degree easy to use of spanner.
The utility model is set to regular polygon through the ratchet ring inner ring at spanner, then the regular polygon with ratchet ring inner ring coupling is arranged in the outer ring of sleeve, with the sleeve ratchet ring inner ring of packing into; Regular polygon trepanning through the sleeve inner ring is nested on the bolt then; Bolt is pulled, because sleeve is whole being encased in inside the ratchet ring inner ring, it is equivalent to spanner and directly is enclosed within on the bolt; Laborsaving convenience when pulling, and also can use for the bolt in small space zone.For the bolt of different model can the fit on different model sleeve.

The specific embodiment
Like Fig. 1,2, a kind of box socket set comprises wrench body and sleeve 9; Wrench body comprises pulls body 1, is arranged on the spanner 7 of pulling body 1 one ends, and spanner 7 is provided with ratchet slot, is provided with turn 8 and ratchet ring 4 in the ratchet slot; Ratchet ring 4 is against tooth piece 6 with matching; Have a circle groove 41 on ratchet ring 4 inwalls, ratchet spring circle 3 is set in the groove 41, said ratchet ring 4 inner rings are regular polygon; Said sleeve 9 outer rings are the regular polygon that is complementary with ratchet ring 4 inner rings, and sleeve 9 inner rings are offered the trepanning 10 that is regular polygon.Described pulling extended an articulated section 11 on the body 1, an articulated joint 71 is set on the spanner 7, and be hinged through screw 2 between articulated joint 71 and the articulated section 11.
When the spanner of the utility model used, the sleeve 9 of choosing suitable types was packed in the ratchet ring 4, and the regular polygon trepanning 10 with sleeve 9 inner rings is enclosed within on the corresponding bolts then, pulls body 1 and just can pull bolt.When the spanner of the utility model used, the sleeve 9 of choosing suitable types was packed in the ratchet ring 4, and the regular polygon trepanning 10 with sleeve 9 inner rings is enclosed within on the corresponding bolts then, pulls body 1 and just can pull bolt.Sleeve 9 can be made the bolt or the screw of the corresponding unlike signal of a variety of models, and promptly the trepanning 10 of sleeve 9 inner rings can be offered the regular hexagon that varies in size according to the model of bolt.
