A hollow cavity is arranged inside the corresponding upper toothed opening for accommodating the righting body, and both sides of the lower part thereof are provided with concave steps matched with the jagged convex steps. The righting body is hung with a return spring, and the return spring is arranged inside a through hole which is arranged on the upper part of the upper toothed opening. The return spring is hung and fixed on the upper part of the upper toothed opening. The utility model has the advantages of high stability, good reliability, high work efficiency, simple structure, and convenient use.
Description
The utility model relates to the hardware ﹠ tools technical field, refers to a kind of opening monkey wrench especially.
At present, the monkey wrench that uses is a kind of common tool, its appearance is replenishing complete open-end wrench, though the opening monkey wrench have use flexibly, advantage easily, but also exist the shortcoming of poor stability simultaneously, promptly stability is not as double offset ring spanner, for example: opening size instability, easier in use skid etc.For now, still there is not to improve the opening monkey wrench appearance of stability.
The purpose of this utility model provides a kind of can opening adjustable, can improve stability in use, reliability again, anti-skidding monkey wrench easy to use.
For achieving the above object, the utility model is taked following design: a kind of anti-skidding monkey wrench, the last age of a draught animal, following dental lamina, adjusting handle, tooth bar, spanner handle, wrench body are arranged, it is characterized in that: last age of a draught animal the place stud with the segment shape deflectable on dental lamina, should go up the dental lamina middle part and be protruding with semicircular centralizer body, its bilateral symmetry is provided with jagged boss rank, is provided with the cavity of ccontaining centralizer body in the last age of a draught animal of correspondence, and there are the concave station rank of matching with zigzag boss rank both sides, its underpart; Rising to the bait at centralizer body hangs with a back-moving spring, and this back-moving spring is set in the through hole that age of a draught animal top is provided with, and articulates the top that is fixed on the age of a draught animal.
In the cross-under of the upper end of adjusting handle the damping spring sheet is arranged.
Vertical tooth rack is provided with a cross-drilled hole on wrench body, in this cross-drilled hole, be provided with one fen retaining spring, the front end of this spring is pressed and is being put a steel ball, spacing is provided with the gear pit respectively on the tooth bar of the corresponding contact of steel ball, this steel ball is under minute effect of retaining spring, just can crouch in the gear pit, be provided with plug in minute rear end of retaining spring.
On upper and lower dental lamina face, be provided with anti-skidding indentation face.
Outer end at upper and lower dental lamina is provided with chamfering.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 3 is that Figure 1A is to schematic diagram
Fig. 4 is the utility model user mode schematic diagram
Referring to Fig. 1, Fig. 2, shown in Figure 3: a kind of anti-skidding monkey wrench, the last age of a draught animal 7, following dental lamina 1, adjusting handle 17, tooth bar 19, spanner handle 18, wrench body 15 are arranged, be characterized in: the last ages of a draught animal 7 place stud with the segment shape deflectable on dental lamina 4, should go up dental lamina 4 middle parts and be protruding with semicircular centralizer body 20, its bilateral symmetry is provided with jagged boss rank 21,22, be provided with the cavity 6 of ccontaining centralizer body in the last age of a draught animal 7 of correspondence, there are the concave station rank 24 of matching with zigzag boss rank both sides, its underpart; Rising to the bait at centralizer body 20 hangs with a back-moving spring 8, and this back-moving spring 8 is set in the through hole 9 that age of a draught animal top is provided with, and articulates the top that is fixed on the age of a draught animal 7.
In the cross-under of the upper end of adjusting handle 17 damping spring sheet 16 is arranged.
Vertical tooth rack is provided with a cross-drilled hole 13 on wrench body 15, in this cross-drilled hole 13, be provided with one fen retaining spring 12, the front end of this spring is pressed and is being put a steel ball 11, spacing is provided with gear pit 10 respectively on the tooth bar 19 of steel ball 11 corresponding contacts, this steel ball is under minute effect of retaining spring 12, just can crouch in the gear pit 10, be provided with plug 14 in minute rear end of retaining spring 12.
On upper and lower dental lamina face, be provided with anti-skidding indentation face 3.
Be provided with chamfering 2 in the outer end of upper and lower dental lamina.
Referring to shown in Figure 4: the fixing last age of a draught animal 7 of monkey wrench upper opening portion be embedded in one can do circular arc dislocation sliding motion on dental lamina 4, should go up dental lamina 4 and be the segment shape substantially, the centre is a centralizer body 6, its bilateral symmetry has zigzag step 21,22, the formed waveform of this zigzag step is a kind of composite wave-shape, and it is that imaginary pivot during with the rotary work of spanner is that the center of circle is done circle, be basic point formation; Now rotate to be the example explanation course of work: when being tapped to workpiece with spanner with the people with holding spanner forward work (being the right hand) ordinary grip spanner up time, such as the afterburning starting stage behind the nut 23, because of there are the gap in nut and wrench opening, nut makes on its hexahedron gradually passively, following angle part and spanner be dental lamina 4 up and down, 1 contact, continuation rotation along with spanner, because the special pearl shape of upper tooth is arranged, force the last dental lamina of close wrench opening inboard to be retreated so can regard the last contact point of nut as towards the back, be directed at its upper tooth bladed saw dentation inclined-plane that is combined into arc and the counterpart on the upper tooth body and produce the camber line displacement, finally make dental lamina just motion to left down, motion by power is decomposed, a power that is close to the direction of extrusion to nut appears at last dental lamina, the effect of " hugging " nut promptly occurred, this effect prevents that just the spanner instability is needed; The square to left down slippage of last dental lamina, the plate emaciated face of dental lamina is from parallel relation about also making, formation is for the outer little interior big opening shape of nut and wrench opening, this opening shape firmly is locked in nut in the wrench opening, after the gap was overcome by the slippage of last dental lamina, the torsion of the special spanner of people then acted on nut fully and screws on the resistance, after last spanner is finished turning clockwise of a stroke, return and break away from nut to the right, the age of a draught animal of lasting this moment, interior back-moving spring then spurred the upper tooth sheet reset.
To make indentation planar for the face of dental lamina up and down of this spanner in addition, changed the very smooth shape in common spanner top and bottom, and this plays positive role to improving spanner stability; Also have this wrench opening end to carry out chamfered, it is favourable that guiding nut is entered opening, improved the overall performance of spanner.
The utility model has partly been set up the spring damping sheet that prevents that the undue pine of adjusting handle from living in the adjusting of existing monkey wrench, and, bring convenience for actual use for spring, the steel ball that is provided with by nut dimension series stepping, the grading machine structure that reaches the gear pit composition of going up on the dental lamina section of rack.
This anti-skidding monkey wrench is the improvement that unstability has been made essence to the important disadvantages of original monkey wrench, people have been eliminated in use since easily factor such as slippage cause the person and equipment to injure this potential safety hazard, also improved operating efficiency simultaneously.
The utility model advantage is: can improve stability in use, and reliability and operating efficiency, and simple in structure, Easy to use.
