Abstract

The utility model relates to a high-speed open and close wrench. An endless screw supported by a spring engages with racks by elastic force; the endless screw is disengaged from racks by pressing the endless screw. The moveable clamping jaw can quickly be adjusted within the range of a spacing slide slot according to the different diameters of the nuts. The utility model has the advantages of simple structure, simple manufacture and convenient operation. The ordinary adjustable wrench can also be remolded to the structure of the high-speed open and close wrench.

Description

The quickly opening and closing spanner

A kind of quickly opening and closing spanner belongs to hand tools.

In people's spanner used in everyday, see so that adjustable wrench more.It can regulate jaw extended distance and easy to use and very popular arbitrarily with it.But this spanner wants repeated multiple times adjusting scroll bar just can achieve the goal when being used for the nut of different-diameter, and is time-consuming, reduces work efficiency.Chinese patent 88221054.8 discloses " a kind of quickly opening and closing spanner ", can reach the purpose of jaw quickly opening and closing.But its structure is comparatively complicated, is difficult for processing, and cost is higher, and existing adjustable wrench can not be transformed into the quickly opening and closing spanner easily.

The purpose of this utility model be exactly propose at weak point above-mentioned in the prior art a kind of simple in structure, be easy to make, both can regulate in normal way, but quick adjustment again, and can easily now the quickly opening and closing spanner that adjustable wrench is transformed into quick adjustment will be had.

The purpose of this utility model is achieved through the following technical solutions.

Two of scroll bar axle is provided with spring eye along the direction of spanner handle in spanner, and two of scroll bar axle is by spring-loaded.The space that can satisfy scroll bar axle stroke is left on the top of spring eye, and the distance between scroll bar axle and the spring eye upper edge is slightly larger than scroll bar and the out-of-gear distance of gear.Have limit sliding chutes longitudinally on the tooth bar that is connected as a single entity with movable jaw, and the position corresponding with limit sliding chutes is provided with spacer pin on spanner.

Advantage of the present utility model and good effect:, make scroll bar and tooth bar often be in engagement owing to adopt the structure of spring-loaded scroll bar.When compressing scroll bar that is pressuring spring, scroll bar can break away from engagement with tooth bar.Size according to the nut diameter, movable jaw is regulated rapidly in the scope of limit sliding chutes, having overcome in the past adjustable wrench will repeatedly regulate with No. 88221054.8 patent structure complexity repeatedly, be difficult for processing, the higher deficiency of cost, and can transform existing adjustable wrench, make it become a kind of quickly opening and closing spanner.

The drawing of accompanying drawing is described as follows:

Accompanying drawing is a structural representation of the present utility model.

In the accompanying drawing: 1. movable jaw 2. tooth bars 3. scroll bar axles 4. scroll bars 5. springs 6. spring eyes 7. spanners 8. spacer pins 9. limit sliding chutes

Now reach embodiment in conjunction with the accompanying drawings the utility model is done a description.

Overall structure of the present utility model has been shown in the accompanying drawing.Be equipped with spring 5 in the spring eye 6 at scroll bar axle 3 two, by the elastic force supporting of spring 5, scroll bar 4 often is in engagement with tooth bar 2.Distance between spring eye 6 upper edges and the scroll bar axle 3 is slightly larger than scroll bar 4 and tooth bar 2 out-of-gear distances, compressing scroll bar 4 that is pressuring spring 5, can make scroll bar 4 and tooth bar 2 break away from engagement, thereby make movable jaw 1 along the 9 random quick adjustment distances of the limit sliding chutes on the tooth bar 2.On the relevant position of spanner 7 and limit sliding chutes 9, spacer pin 8 is housed also,, and can prevents that also tooth bar 2 from outwards coming off with the range of assurance tooth bar 2.

Claims

1, a kind of quickly opening and closing spanner, constitute by spanner, movable jaw, scroll bar and scroll bar axle, tooth bar and spanner handle, the two that it is characterized in that the scroll bar axle is by the spring-loaded that is placed in the spring eye, and the distance between scroll bar axle and the spring eye upper edge is slightly larger than scroll bar and the out-of-gear distance of tooth bar; Have limit sliding chutes with the tooth bar afterbody of movable jaw one, and the position corresponding with limit sliding chutes is provided with spacer pin on spanner.
