Abstract

The utility model relates to a fastener instrument technical field especially relates to a spanner, including the spanner, handle is connected to spanner one end, and the storage tank of holding nut is seted up on spanner other end surface, the border of storage tank is provided with the lug, the utility model discloses can dismantle nut and gasket simultaneously get off, the process is convenient, swift, and the practicality is strong, and the spanner border is if not provided with the lug and just can't dismantle lock nut, plays the theftproof function.

Description

A kind of spanner

Technical field

The utility model relates to the fastener tool technical field, relates in particular to a kind of spanner.

Background technology

Present most of equipment or instrument have nut, and existing nut only needs common wrench just can disassemble, and make the equipment or the instrument that need the nut fixed position have great potential safety hazard like this.

Stop nut comprises nut and pad, during dismounting, pad blocks nut and can not rotate, so nut need be disassembled with pad, dismantle with common wrench, because common wrench can only rotating nut, rotating nut by force, can damage the fixture block on nut and the pad, so be badly in need of a kind of spanner that nut and pad can be disassembled simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of spanner at the deficiencies in the prior art, the utility model can disassemble nut and pad simultaneously, and operation is convenient, fast, and is practical, just can't not dismantle stop nut if the spanner edge is not provided with projection, play anti-theft feature.

For achieving the above object, a kind of spanner of the present utility model comprises spanner, and spanner one end connects handle, and spanner other end surface offers the storage tank of ccontaining nut, and the edge of described storage tank is provided with projection.

As preferably, one side the aliging of described projection and storage tank, and be positioned at the centre position on this limit.

As preferably, described projection is shaped as cuboid or cylinder.

As preferably, described projection and described spanner are one-body molded.

As preferably, the cross section of described storage tank is hexagon.

As preferably, described storage tank is provided with fillet between adjacent two limits.

As preferably, described spanner is cylindric.

As preferably, described spanner is fixedlyed connected with handle.

The beneficial effects of the utility model: the pad of stop nut is provided with fluting, during spanner dismounting nut, nut is placed in the storage tank, then insert in the fluting of pad with the projection that storage tank aligns on one side, link together with pad behind the nut screwing clamping, rotating spanner can disassemble nut with pad, operation is convenient, fast, and is practical.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

Embodiment one

As shown in Figures 1 to 4, a kind of spanner comprises spanner 1, and spanner one end connects handle 2, and spanner 1 other end surface offers the storage tank 11 of ccontaining nut 3, and the edge of described storage tank 11 is provided with projection 12.

The pad 4 of the stop nut 5 that present embodiment need be dismantled is provided with fluting, during spanner dismounting stop nut 5, nut 3 is placed in the storage tank 11, insert in the fluting of pad 4 with 12 of the projections that storage tank 11 aligns on one side, nut 3 is tightened the back and is linked together with pad 4, and rotating spanner can disassemble nut 3 with pad, operation is convenient, fast, and is practical.

In the present embodiment, described projection 12 aligns with one side of storage tank 11, and be positioned at the centre position on this limit, nut 3 is hex nut, the fluting of pad aligns with one side of nut 3, during spanner dismounting nut 3, makes things convenient for projection 12 to insert in the fluting, thereby unscrew pad, nut 3 is disassembled with pad.

In the present embodiment, described projection 12 is shaped as cuboid or cylinder, according to the fluting shape of pad 4 and the shape of relative set projection 12.

In the present embodiment, described projection 12 and described spanner 1 are one-body molded, save material.

In the present embodiment, the cross section of described storage tank 11 is hexagon, and nut 3 is hex nut, offers hexagonal storage tank 11, when dismounting, and can ccontaining nut 3.

In the present embodiment, described storage tank 11 is provided with fillet between adjacent two limits, is convenient to nut 3 and is placed in the storage tank 11, the sliding friction when reducing nut 3 and being placed in the storage tank 11.

In the present embodiment, described spanner 1 is cylindric, is convenient to the user and uses.

In the present embodiment, described spanner 1 is fixedlyed connected with handle 2.

Embodiment two

As shown in Figure 5, present embodiment is another embodiment of the utility model, the difference of present embodiment and embodiment one is: described projection 12 numbers are two, the top of described handle 2 horizontally sets and spanner 1, and fixedly connected in spanner 1, when stop nut 5 sizes are big, a projection 12 is difficult to drive pad 4 and nut 3 rotations, and projection 12 and spanner 1 are disconnected, so two projections 12 need be set, the top of handle 2 horizontally sets and spanner 1 makes things convenient for user's application of force.

Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
