Utility model content
The technical problems to be solved in the utility model is that in view of the above shortcomings of the prior art, and providing one kind can fast velocity modulation
Save the torque spanner of opening.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of torque spanner that can quickly adjust opening, including wrenching bar, the wrenching bar front end are equipped with driving end one, institute
State one lower end of driving end and be correspondingly provided with Flexible spanner at hand two, two tail portion of driving end is equipped with step pin axle, the wrenching bar with
Connecting portion between driving end one is equipped with arc dentation gain, and the shaft part of the step pin axle is connected to arc dentation gain
It is interior.
Further, the step pin axle includes arc shaft part and stepped plate, the driving end two by itself end face and
Stepped plate and arc dentation gain clamping connection, the shaft part is connected in arc dentation gain, and the extrados and arc of shaft part
Each section of arc-shaped gear is mutually clamped in shape dentation gain.
Further, the outer arc vertex of surface of the arc shaft part is to end face distance a less than each section in arc dentation gain
Arc tip distance b.
Preferably, clamping opening is correspondingly provided between the driving end one and driving end, the clamping opening includes clamping opening face one and folder
Mouth face two, connects between the clamping opening face one and clamping opening face two at obtuse angle, and one surface of clamping opening face is equipped with latch.
Preferably, the wrenching bar tail portion is socketed with rubber antiskid set.
Compared with prior art, one kind of the utility model can quickly adjust the torque spanner of opening, pass through step pin axle
Slide and position in arc dentation gain, can with Quick-adjusting wrench is first and the distance between driving end two, and then tighten or
Fastener is unscrewed, structure design is simple, and it is easy to operate, it is able to ascend the working efficiency of operator.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of torque spanner that can quickly adjust opening, including wrenching bar 1,1 front end of wrenching bar are set
There is a driving end 1, one 2 lower end of driving end is correspondingly provided with Flexible spanner at hand 23, and 23 tail portion of driving end is equipped with step
Pin shaft 4, the step pin axle 4 include arc shaft part 41 and stepped plate 42, the connection between the wrenching bar 1 and driving end 1
Position is equipped with arc dentation gain 5, and the shaft part 41 of one side step pin axle 4 is connected in arc dentation gain 5, on the other hand pulls
23 by itself end face and stepped plate 42 and 5 clamping connection of arc dentation gain at hand, in torque spanner work, by spanner
Opening between first 2 and driving end 23 is adjusted to required openings of sizes, passes through the extrados and arc dentation waist of shaft part 41
The arc-shaped gear of correspondent section is mutually clamped in slot 5.
Further, in order to quickly adjust the openings of sizes of torque spanner, the shaft part 41 is arc cylinder, and arc shaft
The outer arc vertex of surface of section 41 is to end face distance a6 less than each section of arc tip distance b7 in arc dentation gain 5.
Preferably, clamping opening 8 is correspondingly provided between the driving end 1 and driving end, the clamping opening 8 includes clamping opening face 1
It connects, and presss from both sides at obtuse angle between the clamping opening face 1 and clamping opening face 2 82 in order to facilitate clamping fastener with clamping opening face 2 82
Mouth one 81 surface of face is equipped with latch.
Preferably, 1 tail portion of wrenching bar is socketed with rubber antiskid set 9.
In actual operation, rotary spanner head 23 counterclockwise first, since the outer arc vertex of surface of shaft part 41 is to end face distance
A6 is less than each section of arc tip distance b7 in arc dentation gain 5, and step pin axle 4 can be free to slide in arc dentation gain 5, choosing
Suitable opening angle is selected, then rotates clockwise driving end 23, so that the extrados of shaft part 41 blocks in arc dentation gain 5
Fastener can be tightened or be unscrewed to the arc-shaped gear of correspondent section.
The utility model is not limited to the embodiment described, and those skilled in the art is not departing from the utility model
Spirit is that still may make some modifications or changes, therefore the rights protection scope of the utility model is with claims in the open scope
Subject to the range of restriction.
