Abstract
The utility model relates to a polygonal wrench which comprises a wrench body. The polygonal wrench is characterized in that a ratchet wheel is arranged on the front end of the wrench body, a polygonal hole is arranged on the center of the ratchet wheel, and a slide block is arranged on the wrench body. The front end of the slide block is provided with teeth which are engaged with the ratchet wheel, and the back end of the slide block is provided with a top spring. The utility model cancels the coat of the traditional wrench, and combines with the advantages of the ratchet wheel wrench and the box-end wrench, which makes the polygonal wrench more applicable.
Description
The utility model relates to a kind of hand tools, particularly a kind of polygonal spanner.
The CN91210540.2 utility model patent provides a kind of novel ratchet spanner (as shown in Figure 1).The wrench body of this spanner is designed to the center symmetrical expression, makes anterior volume-diminished, but because its structure is limit, and head outer diameter is still bigger, makes that use is limited under many situations, as Fig. 2, shown in Figure 3.
The purpose of this utility model provides a kind of spanner of new structure, and it can overcome the existing in prior technology shortcoming.
The purpose of this utility model is achieved in that it comprises wrench body, it is characterized in that the wrench body front end is equipped with ratchet, and the ratchet center has polygonal holes, and slide block is housed on the wrench body, and slip front band tooth is meshed with ratchet, and the top spring is equipped with at the slide block rear portion.
The utility model is owing to the overcoat of having cancelled conventional spanner, and is unrestricted in the use of the occasion shown in Fig. 2 so anterior diameter is less, in addition because the ratchet center is a polygonal holes, so can be used for occasion shown in Figure 3.In sum, the utility model combines the advantage of ratchet spanner and double offset ring spanner, makes it more suitable.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a spanner structure schematic diagram in the prior art.
Fig. 2, Fig. 3 are the schematic diagrames that spanner of the prior art is restricted in use.
Fig. 4 is the structural representation of a kind of specific embodiment of the present utility model.
Fig. 5 is the A-A cutaway view of Fig. 4.
1 is that ratchet, 3 is wrench body among the figure, has slideway on the wrench body, and slide block 2 is housed in the slideway, slip front band tooth, and with ratchet engaged, top spring 4 is equipped with at the slide block rear portion, and the ratchet center has through hole, and top is polygonal holes, and the bottom is a circular hole.The clamp 5 of the axial restraint of ratchet by having boss, between overcoat 6 and the ratchet movingly.
