Description

Rotary spanner

Technical field

The utility model is relevant with spanner, refers to especially a kind of rotary spanner of capable of regulating use angle.

Background technology

Spanner is that a kind of rotating bolt, nut or other of being used for are difficult to the hand-held tool of the workpiece rotating with hand, but in narrow operating space or have around while operation under the stopping of other works, user just must constantly change gripping angle, just can make driving end follow the workpiece matching with it positively to connect together, such mode of operation will certainly cause sizable puzzlement to user.

In order to address the above problem, it is the angle adjustment of controlling driving end between driving end and spanner bandle by the collocation of backstay and adjusting lever that TaiWan, China is announced I241940 Patent Case, but commonly use in Patent Case at this, backstay and adjusting lever are the configurations that adopts tilting, so will certainly there is the problem of complex structure and operation effort, therefore structurally have necessity of improvement.

Summary of the invention

For the problems referred to above, main purpose of the present utility model is to provide a kind of rotary spanner, and it is simple in structure and easy to operate.

For achieving the above object, the rotary spanner of one provided by the utility model, is characterized in that including: one first wrench body, has one first driving end and one first lever, one end of described the first lever connects described the first driving end, and the other end of described the first lever has a pivot hole; One second wrench body, there is one second driving end, one second lever, and a pivot, one end of described the second lever connects described the second driving end, described in be pivotally connected to the other end of described the second lever and can be arranged in rotationally in the pivot hole of the first lever of described the first wrench body; One elastic component, be sheathed on the pivot of described the second wrench body and be resisted against the first lever of described the first wrench body and the second lever of described the second wrench body between.

In above-mentioned the technical solution of the utility model, the pivot hole of described the first wrench body has a macropore portion, an aperture portion, an and first rank portion that is connected described large and small hole portion, the pivot of described the second wrench body has a large axial region, a little axial region, and the second-order portion of the described large and small axial region of a linking, the two ends of described elastic component are connected to respectively described first, second rank portion.

The large axial region of the pivot of described the second wrench body is arranged with an O shape ring, and described O shape ring is connected between the end face of the first lever of described the first wrench body and the end face of the second lever of described the second wrench body.

The aperture portion in the pivot hole of described the first lever has an inner groove, and the little axial region of the pivot of described the second lever has an outer groove, between described inside and outside annular groove, is provided with a clasp.

Adopt technique scheme, between first, second wrench body of the present utility model, can relatively rotate to adjust use angle, and the elastic resistance that can provide by elastic component after adjusting to suitable angle and obtain locating effect.

Detailed description of the invention

In order to describe structure of the present utility model, Characteristic in detail, the following preferred embodiment of existing act also coordinates brief description of the drawings as follows.

As shown in Figures 1 and 2, rotary spanner 10 of the present utility model includes one first wrench body 20, one second wrench body 30, and an elastic component 40.

The first wrench body 20 has one first driving end 21 and one first lever 22, the first driving end 21 is interior can install according to actual needs a ratchet carriage 12, one end of the first lever 22 connects the first driving end 21, the other end of the first lever 22 has a pivot hole 23, as shown in Figure 3, pivot hole 23 has a macropore portion 24, an aperture portion 25, and the first rank portion 26 of the large and small hole of a linking portion 24,25, is wherein separately provided with an inner groove 252 in aperture portion 25.

The second wrench body 30 has one second driving end 31 and one second lever 32, the second driving end 31 is interior can install according to actual needs another ratchet carriage 14, one end of the second lever 32 connects the second driving end 31, the other end of the second lever 32 extends a pivot 33 outward with axial manner, pivot 33 is arranged in the pivot hole 23 of the first lever 22 of the first wrench body 20 and has a large axial region 34, a little axial region 35, and the second-order portion 36 of the large and small axial region 34,35 of a linking, be wherein separately provided with an outer groove 352 at the end of little axial region 35.Time be embedded in inside and outside annular groove 252,352 by a C shape clasp 50 in assembling, make after assembling completes, can relatively rotate between first, second wrench body 20,30 and cannot move to axial.It should be added that in addition, affect the rotation smooth degree between first, second wrench body 20,30 for fear of extraneous dust or water, by the sheathed O shape ring 52 of large axial region 34 of the pivot 33 in the second wrench body 30, and O shape ring 52 is connected between the end face of the first lever 22 of the first wrench body 20 and the end face of the second lever 32 of the second wrench body 30, for water proof and dust proof effect is provided.

Elastic component 40 (at this taking Compress Spring as example) be sheathed on the pivot 33 of the second wrench body 30 and be connected to the first rank portion 26 of the first wrench body 20 and the second-order portion 36 of the second wrench body 30 between, as shown in Figure 3, for providing elastic resistance to first, second wrench body 30.

In the time will adjusting use angle, first with the hands hold the first lever 22 of the first wrench body 20 and the second lever 32 of the second wrench body 30, then force first, second wrench body 20,30 to relatively rotate, once discharge again the rotation strength to first, second wrench body 20,30 after turning to suitable angle, the elastic resistance that first, second wrench body 20,30 is provided by elastic component 40 produces locating effect, as shown in Figure 4, now complete the adjustment of use angle.Hence one can see that, and rotary spanner 10 of the present utility model has more simple structure compared to located by prior art, also laborsaving many in operation, thereby can reach the object that increases ease of use.
