Description

Idle running reset adjustable spanner structure

[technical field]

The structure of a kind of reset monkey wrench that dallies of the utility model, the Structure Improvement Design that espespecially a kind of its opening of monkey wrench idle running resets.

[background technology]

The monkey wrench commonly used, spanner is pulled with turn working substance after chimeric stressed working substance, spanner and working substance at angle after, spanner must be departed from working substance, and make spanner reversion to the angle of initial chimeric working substance, chimeric working substance again, and then pull spanner, its the chimeric action departed from of this working method, need suitable space, and course of action is complicated with inconvenience, industry is for solving this shortcoming, improve the operating efficiency of monkey wrench, just like No. I340065th, Taiwan certificate number, No. I429509, the utility model shown in patent such as No. I354605, the common ground of these three patents is all linked in the backing pin of handle with one, assembly or adjustment assembly axostylus axostyle is adjusted by its gear monkey wrench processed, the important key of idle running reset is made as monkey wrench, right aforesaid Patent Utility Model has following all shortcomings and does not conform in practicality:

1. component part is complicated, because monkey wrench is instrument, need bear suitable strength when therefore operating, and the part of composition is complicated, mean that suitable fault rate and the strength of bearing may lower than mean levels;

2. because the volume of spanner has certain restriction, part composition is many, represents component part volume and intensity is less poor, easily damages, though can make with preferably material, relatively will improve material cost and processing cost;

3., because component part is complicated, so assembling relatively not easily, packaging qualification rate also decreases, and then cost is increased again.

4. gear monkey wrench processed adjustment assembly or adjustment assembly axostylus axostyle and be linked in the backing pin of handle, all by the elastic force start of spring, if slightly burr or surface smoothness are not good for part, easy blocking cannot action, and the function of spanner idle running reset is lost thereupon.

The problems referred to above, obviously have much room for improvement.

[utility model content]

The utility model provides a kind of structure of the reset monkey wrench that dallies, its object is to, the screw assembly of adjustment wrench opening, except can the position in spiral adjustment opening jaw portion, and can do spiral axle center to rectilinear motion, this rectilinear motion is then by the restriction of handle, its restriction can be removed by the swing of handle, when making monkey wrench turn nut or screw, because spanner swings by user's operation, and then the opening of spanner is made to have the action of folding idle running reset.

By the technical solution of the utility model, details are as follows below:

A kind of idle running reset adjustable spanner structure, is characterized in that, comprising:

Wrench body, its one end is provided with a jaw portion, the other end is then arranged with a groove, bottom land is provided with a hole, and wrench body pivot place is then equipped with a rectangular opening, and nearly jaw portion is then arranged with a straight trough, by this straight trough side, body periphery is equipped with the hole that is parallel to straight trough, and the rectangular opening at wrench body pivot place is also run through in this hole, and closely this rectangular opening is other is equipped with a hole;

Movable jaw portion, its one end is provided with a guide rod, is hubbed in a straight trough in the nearly jaw portion of wrench body, and this guide rod body of rod is approximate spline-simulating;

Adjustment assembly, be hubbed in the rectangular opening of wrench body, there is pass through aperture at its pivot place, one end, and outer peripheral edge is set to worm, and be able to engage with movable jaw portion guide rod spline-simulating;

Adjustment assembly axostylus axostyle, its one end is provided with screw thread, is hubbed in adjustment assembly, and is fixed at the hole that wrench body is parallel to straight trough;

Handle, is arranged in the recessed groove of the wrench body jaw portion other end;

Push rod, is arranged in the bottom land hole of the wrench body jaw portion other end.

Wherein, handle, its end, one end is in the gear portion of approximate L shape, and its proximal edges place is equipped with a hole, and is pivoted wherein by a pivot pin and is arranged in the other hole of wrench body rectangular opening, and the gear portion one terminal block system of this approximate L shape lives the end of adjustment assembly.

Wherein, push rod, its one end is equipped with a spring, is arranged in the bottom land hole of the wrench body jaw portion other end, and props up the gear portion that handle is similar to L shape.

The utility model advantage and effect are:

1. the easy production cost of part simplification assembling is low.

2. part strength is higher than commonly using product, and spanner work is better than the product of commonly using.

3. the utility model is because of the higher not easily fault of part strength, guarantees that using function is normal.
