Abstract
The utility model relates to a ratchet wrench, which comprises a handle body and a ratchet arranged in the handle body. A ratchet pawl capable of tightly matching with the ratchet is arranged in the meniscus groove of the handle body, a press spring is sheathed on the joint of the ratchet pawl, and a snap spring is arranged in the snap spring groove of the ratchet and is placed in the round hole of the handle after pressed. The utility mode has advantages of large torsion moment, reliable performance, good appearance, small size, and convenient and flexible rotation.
Description
Technical field
The utility model relates to a kind of ratchet type spanner.
Background technology
It all is corresponding 12 jiaos of hole that plum in the tradition is driven spanner, in certain locus, when spanner turns to certain angle, must take off spanner from workpiece, and translation-angle puts workpiece again, can continue to pull workpiece, and is very inconvenient.And the ratchet spanner in the box spanner, just operation rapidly, continuously easily.But it need attach a sleeve, can the turn workpiece.The structure of spanner is also complicated, and volume is also big.
Summary of the invention
It is a kind of simple in structure, reliable that the purpose of this utility model is to provide, and the ratchet one-way plum that can unidirectionally work continuously is fast driven spanner.
The technical solution of the utility model is as follows: the ratchet one-way plum drives spanner and comprises the handle body and be located at the interior ratchet of handle body, in the half-moon groove of handle body, be provided with can with the ratchet of ratchet tight engagement, be with stage clip on the connector of ratchet, be provided with jump ring in the jump ring groove of ratchet, put into the circular hole of handle body after jump ring clamps.
Aforesaid ratchet one-way plum is driven spanner, and wherein, ratchet adopts the chrome-vanadium steel material, is provided with 12 jiaos of endoporus of fillet type, and 72 teeth adopt recessed tooth.
The utility model as driving member, can be return the position of handle bar with 72 a tooth papillaes wheel with 12 jiaos of holes low-angle, unscrews and screw workpiece easily rapidly, continuously.In addition, the utility model has carried out technological improvement, innovation to the outer straight-tooth on traditional ratchet, has invented recessed straight-tooth ratchet, and extruding causes damage to handle body opening wall to avoid pointed tooth, has improved the quality of product greatly.This torque of wrenches square is big, and dependable performance is attractive in fashion, small and exquisite, rotates light, flexible.

The specific embodiment
As Fig. 1, shown in Figure 3, the ratchet one-way plum drives spanner and comprises handle body 1 and the ratchet 5 that is located in the handle body 1, in the half-moon groove of handle body 1, be provided with can with the ratchet 3 of ratchet 5 tight engagement, be with stage clip 2 on the connector of ratchet 3, be provided with jump ring 4 in the jump ring groove of ratchet 5, put into the circular hole of handle body 1 after jump ring 4 clamps.Ratchet 5 adopts the chrome-vanadium steel material, is provided with 12 jiaos of endoporus of fillet type, and 72 teeth adopt recessed tooth.Rotating ratchet 5 can be heard clear and melodious clatter, clatter sound.
As shown in Figure 2, as external force F during to the direction of arrow application of force, ratchet 3 is subjected to the extruding of half-moon groove arc surface, meshes together tightly with ratchet 5, can unscrew nut.After handle body 1 drove ratchet 5 and nut and turns to certain angle together, when handle body 1 clockwise direction pushed back, just together with ratchet 5 disengagements, handle body 1 just can be done any rotation to ratchet 3, and minimum angles is 5 °.In case handle body 1 is done when counterclockwise rotating again, handle body 1, ratchet 3 and ratchet 5 mesh together tightly again immediately and unscrew nut, thereby have realized operation rapidly, continuously.
In like manner, the handle body turns over a body, with regard to another the unidirectional rotation of interchangeable do, promptly screws nut.
Handle body of the present utility model selects for use the chrome-vanadium steel finish forge to form, and circular hole is straight tubular in the spanner, crosses the axis, and there is the one and a half months groove centre.Ratchet is the chrome-vanadium steel material, 12 jiaos of endoporus of fillet type, and its 72 teeth have adopted recessed straight-tooth technology, have avoided the damage of pointed tooth to the spanner inner hole wall, have improved the quality of product greatly.Ratchet has been selected high-intensity powder metallurgy for use, meshes the high moment of torsion that has guaranteed spanner reliably with ratchet 72 teeth.Stage clip and jump ring all adopt quality material to make with extra care and form, and reasonably Element Design and advanced processing technology have guaranteed the very high moment of torsion of spanner, rotate flexibly and fast, and be attractive in fashion small and exquisite.
