Abstract

The utility model discloses a novel valve spanner which comprises a spanner handle and a spanner head containing part, wherein the spanner handle is made by a steel plate, and the spanner head containing part and the spanner handle are integrally arranged to form a whole body. The novel valve spanner is characterized by further comprising a spanner head washer layer with a spanning hole, a groove is punched on the bottom surface of the spanner handle, a hole is punched in the center of the spanner head containing part, and the spanner head washer layer is welded in the hole of the spanner head containing part. The novel valve spanner is ingenious in structure, casting is not required in the whole process, so a casting hole is not formed in the spanner handle, the problem that the spanner handle is easily broken due to casting in the prior art is solved, and the service life of the valve spanner is prolonged; and moreover, the spanner handle is made by the steel plate, the surface of the spanner handle cannot have a casting hole and the surface of the spanner cannot have a certain gap due to casting, so the use accuracy is improved, and the novel valve spanner is good in handfeel and attractive in appearance and has good practicability.

Description

The novel valve spanner

Technical field

The utility model belongs to the tap wrench field, is specifically related to a kind of novel valve spanner.

Background technology

The tap wrench of prior art all is provided with the casting mouth on pinch bar, be used for the integrally casting wrench, and there is certain deficiency in it; The tap wrench of casting is more coarse; Have Sha Konghui to make on the surface to pull the surface to have certain clearance, during use the degree of accuracy not high, and owing to there is casting mouthful at the handle place; Make spanner fracture easily in use, service life is short.

Summary of the invention

The purpose of the utility model provides a kind of high and novel valve spanner of easy fracture, long service life not of the degree of accuracy that uses.

The technical scheme that realizes the utility model purpose provides a kind of novel valve spanner; The driving end placement section that comprises pinch bar that steel plate processes, is wholely set with pinch bar; It is characterized in that: also comprise being provided with the driving end spacer layer of pulling the hole; Be provided with the groove that is stamped to form in the bottom surface of said pinch bar, the center of said driving end placement section is provided with the hole that is stamped to form, and said driving end spacer layer is welded in the hole of driving end placement section.

Further, said driving end spacer layer comprises at least two driving end pad monomers.

Further, the said hole of pulling is square hole or flat hole.

The utlity model has positive effect: the pinch bar that the tap wrench of the utility model is processed by steel plate, driving end placement section and the driving end spacer layer that is welded in the driving end placement section are formed; Punching press is fluted on pinch bar; Be pressed with the hole at driving end placement section centre punch, the driving end spacer layer is welded in the hole, this novel structure; Whole process need not adopt casting process; So on pinch bar, cast mouth, solved the problem of the easy fracture of pinch bar that causes because of casting in the conventional art, prolonged the service life of tap wrench; And, the pinch bar that adopts steel plate to process, can there be certain clearance in its surface because of casting makes the surface have Sha Kongji to make to pull the surface, has improved the degree of accuracy of using, good hand touch, and good looking appearance, practicality is good.

Description of drawings

For the content that makes the utility model is more clearly understood, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein:

Fig. 1 is first kind of structural representation of the utility model;

The specific embodiment

(embodiment 1)

Fig. 1 has shown a kind of specific embodiment of the utility model, and wherein Fig. 1 is first kind of structural representation of the utility model.

See Fig. 1; A kind of novel valve spanner; Comprise pinch bar 1 that steel plate processes, with the driving end placement section 2 that pinch bar 1 is wholely set, also comprise being provided with the driving end spacer layer 4 of pulling hole 3, be provided with the groove 5 that is stamped to form in the bottom surface of pinch bar 1; The center of driving end placement section 2 is provided with the hole 6 that is stamped to form, and driving end spacer layer 4 is welded in the hole 6 of driving end placement section 2.

Driving end spacer layer 4 comprises at least two driving end pad monomers 7.

Pull hole 3 and be square hole 31.

(embodiment 2)

Fig. 2 has shown the another kind of specific embodiment of the utility model, and wherein Fig. 2 is second kind of structural representation of the utility model.

See Fig. 2, present embodiment and embodiment 1 are basic identical, and difference is: pull hole 3 in the present embodiment and be flat hole 32.

Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, the spanner bottom surface in the foregoing description is comparatively speaking, and is not to be the qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
