Abstract

The utility model relates to a rachet wrench which comprises a rachet wrench body and a rachet wheel. A jaw part is arranged on the rachet wrench body, an annular edge is arranged in the jaw part, the rachet wheel is inserted in the jaw part, the middle end of the rachet wheel abuts against the annular edge in the jaw part to clamp the position of the rachet wheel, and the upper end of the rachet wheel is limited to the jaw part by an end cover and a clamping spring. The rachet wrench is compact in structure, the rachet wheel can be easily detached and replaced, rachet wheel tooth pin holes are designed to be formed in the rachet wheel, so that the application face of the rachet wheel is wider, the rachet wheel can be mounted on other equipment conveniently, locking pins can also be connected conveniently, the lock pins and the rachet wheel tooth pin holes abut against each other, and the rachet wheel can be tightly fixed on the rachet wrench body. In addition, a pin, the lock pins and the spring are ingeniously combined, so that the lock pins can be effectively adjusted freely and limitedly, the rachet wheel can be locked, slipping of the rachet wheel is prevented, and the rachet wheel can be replaced. The rachet wrench is reasonable in design, wide in application range, and suitable for mass popularization.

Description

A kind of ratchet spanner

Technical field

The utility model relates to a kind of hand-operated tools, is specifically related to a kind of ratchet spanner.

Background technology

Ratchet spanner, a kind of manual screw tightening tool.The ratchet spanner using at present comprises wrench body and is located at the ratchet device of Wrench head, whole device adopts welding manner to connect, whole device is to be connected as a single entity, non-removable, therefore in use, there is the phenomenon that breaks down in ratchet device or wrench body, just can not recycle, the wasting of resources is more serious, also make cost increase, in addition, in the time running into ratchet device and not mating with nut that needs degree of tightness etc., also will find applicable spanner replaces, rather than replace simply ratchet device, this also gives and uses the people of spanner to bring very large trouble, when particularly going out to carry out maintenance work, need multi-band several different spanners, increase the weight in tool box.

Utility model content

For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of and can dismantles, change ratchet and cost is low, adapt to wide ratchet spanner.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ratchet spanner, comprise ratchet spanner main body and ratchet, in described ratchet spanner main body, there is a nip part, in this nip part, there is an annular edge, described ratchet inserts in this nip part, the middle part of ratchet and the annular edge of nip part offset, and block the position of ratchet, and the top of ratchet is limited in nip part with end cap and jump ring.

Further, described ratchet spanner main body is provided with a passage, and this passage is used for installing lock pin.

Further, described lock pin one end is side grain, and the other end is scarf, and the one end near side grain on lock pin has a pinhole, and this pinhole is used for inserting pin, and side grain one end and the spring of lock pin offset, and scarf one end and the ratchet of lock pin offset.

Further, described pin is connected with lock pin by pinhole, and pin and lock pin orthogonal, pin can limit lock pin slide.

Further, have hook tooth pin-and-hole on described ratchet, the scarf end of this hook tooth pin-and-hole and lock pin offsets, and prevents that ratchet from skidding.

Compared with prior art, the utility model has the advantage of: the utility model compact conformation, ratchet can easy removal, change, and on ratchet, design hook tooth pin-and-hole, make the application surface of ratchet wider, ratchet is convenient to be installed on other equipment, lock pin is also convenient to connect, lock pin and hook tooth pin-and-hole offset, ratchet tightly can be fixed in ratchet spanner main body, in addition, pin, the ingenious combination of lock pin and spring, can be free and limited lock pin be effectively regulated, not only can pin ratchet, prevent that ratchet from skidding, and can change ratchet, recycle ratchet spanner main body, effectively improve resource utilization, reduce costs, this ratchet spanner is reasonable in design, adapt to wide, be applicable to large-scale promotion.

Accompanying drawing explanation

Fig. 1, Fig. 2 are the utility model structural representation.

The specific embodiment

As shown in Figure 1-2, a kind of ratchet spanner, comprises the critical pieces such as ratchet spanner main body 1, ratchet 2, pin 3, lock pin 4 and spring 5.There is a nip part a one end of described ratchet spanner main body, has an annular edge in nip part a, and this nip part a is used for installing ratchet 2; Described ratchet 2 has a through hole b, and ratchet 2 is provided with hook tooth pin-and-hole c, pack ratchet 2 into nip part a, annular edge in one end and the nip part a of ratchet 2 is offseted, block the position of ratchet 2, the other end of ratchet 2 is limited in nip part a through end cap 6 and jump ring 7, and the other end of ratchet 2 and nip part a be equipped with respect to position the groove of placing for end cap 6 and jump ring 7; Described lock pin 4 one end are side grain, the other end is scarf, hook tooth pin-and-hole c on scarf end and the ratchet 2 of lock pin 4 offsets, be used for limiting ratchet 2, side grain end and the spring 5 of lock pin 4 offset, lock pin 4 is contained in the inner passage of ratchet spanner main body 1, is followed successively by from the inside to surface spring 5, lock pin 4 in this passage; Spring 5 is mainly used in limiting slip and the reset lock pin 4 of lock pin 4, on lock pin 4, have a pinhole d, this pinhole d is near the side grain end of lock pin 4, pin 3 is inserted to pinhole d, make pin 3 and lock pin 4 orthogonal, pin 3 can limit lock pin 4 and slide, and pin 3 under external force, can overcome the resistance of spring 5, the position of limited adjusting lock pin 4; Pin 3, spring 5, lock pin 4 and hook tooth pin-and-hole c have played Main Function fixing and dismounting ratchet 2 jointly.

In use, lock pin 4 in ratchet spanner main body 1 passage is under the effect of spring 5 and pin 3, on one end of lock pin 4 and ratchet 2, hook tooth pin-and-hole c offsets, and ratchet spanner main body 1 and ratchet 2 are connected as a single entity, and ratchet spanner main body 1 drives ratchet 2 to rotate under the effect of external force.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these modifications or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment technical scheme of the utility model.
