Abstract

The utility model relates to an automatic location spanner with a pipe wrench function which comprises a handle 1, a half-hexagonal sleeve 2, a pin shaft 3, and a clip ring 9; the half-hexagonal sleeve 2 is hinged on the working end of the handle through the pin shaft 3 and the clip ring 9; the working end of the handle 1 takes the shaft center of the pin shaft as the involute of a base circle; the working end of the handle 1 forced on a cap nut 7 or a pipe 6 through the working inclined plane with a tooth space 8 of a half-hexagonal through hole 4 on the half-hexagonal sleeve 2; a three-way clamp with zero clearance is formed. The utility model with simple structure combines the advantages of an existing spanner and the existing pipe wrench.

Description

Automatic dowelled spanner with pipe vice function

The utility model relates to hand tools, is in particular a kind of automatic dowelled spanner with pipe vice function.

At present, the monkey wrench that people habitually practise uses inconvenient, and work is easily loosening, and chucking power causes for a short time and skids.The back-up wrench size is single, and accommodation is little.Automatic dowelled spanner (the patent No.: ZL94241824.7) be not suitable for the occasion that to use open-end wrench.And they do not have the function of pipe vice.

The purpose of this utility model is exactly that a kind of monkey wrench, box spanner, opening back-up wrench, automatic dowelled spanner with pipe vice function of the function of the advantage of dowelled spanner and pipe vice automatically of integrating is provided for the above-mentioned defective that overcomes prior art.

Technical solution of the present utility model is as follows:

A kind of automatic dowelled spanner with pipe vice function, it includes handle, half hexagonal cover, bearing pin, check ring, half hexagonal has put hexagonal through hole in half, each angle of hexagonal through hole is 120 degree in half, the part outside at half hexagonal cover has the open slot that links with half hexagonal through hole, bearing pin is passed through in the working end of handle, check ring and half hexagonal cover link and just are inserted in the open slot, and act on hexagonal (hexagon)nut or pipe by the hexagonal through hole application of force in half, the axle center with bearing pin that is shaped as of the working face of handle working end is the involute of generating circle, short long and generating circle garden heart off-centre 1/2nd generating circle diameters down on the hexagonal symmetry axle of half hexagon ring.Have teeth groove as the inclined-plane on two of half six interior angle through holes, in last work, clamp hexagonal (hexagon)nut or bite pipe, realize screwing, the cross sectional shape of teeth groove can be triangle, trapezoidal, rectangle, square or with the crossing curve of working face.

Advantage of the present utility model is, compares vary in size with box spanner, opening back-up wrench, and is applied widely, seizes no gap on both sides by the arms; Compare easy to usely with the general activity spanner, loosening, the three-dimensional chucking power is big; To compare applicable situation wider with automatic dowelled spanner; Compare easy to usely with general pipe vice, loosening, it is big that three-dimensional does not have the gap chucking power.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation.

Fig. 2 is the enlarged drawing in teeth groove cross section on two working faces of hexagonal through hole in half among the figure one.

Fig. 3 is the A-A profile of figure one.

As shown in Figure 1-Figure 3, during the utility model work, the working end of handle 1 is inserted in the open slot 5 of half hexagonal cover 2, and it is they are hinged by bearing pin 3 and check ring 9, when hexagonal (hexagon)nut 7 or pipe 6 be inserted in or insert half hexagonal cover 2 half in during hexagonal through hole 4, clockwise direction is moved handle 1, then in half of half hexagonal cover 2 on two inclined-planes on the hexagonal through hole 4 and handle 1 working face point formed and respectively become the three-dimensionals of 120 degree not have the gap clamping hexagonal (hexagon)nut 7 or pipe 6, hexagonal (hexagon)nut 7 or pipe 6 are screwed along with the rotation of handle 1.1 pair on handle arbitrarily the pressure spot of the hexagonal (hexagon)nut 7 of size or pipe 6 all in half on the symmetry axis of hexagonal through hole 4.This clamping force increases along with the increase of working resistance, thus overcome other spanner and pipe vice because of the gap, the phenomenon that can't screw of the defective work piece that becomes flexible, skids.If will oppositely screw, turnback is entangled hexagonal (hexagon)nut 7 or pipe 6 is counterclockwise moved handle as long as spanner turned over.Short long down on the axis of symmetry of hexagonal through hole 4 in half, to adapt to the needs of different size.Two inclined working of hexagonal through hole 4 have teeth groove 8 in half, but simultaneous adaptation six square nuts 7 need with the different operating of pipe 6.Also can pacify the half hexagonal cover 2 of another different size to enlarge its scope of application at the other end dress of handle 1.

Claims

1, a kind of automatic dowelled spanner with pipe vice function, it includes handle 1, half hexagonal cover 2, bearing pin 3, check ring 9, it is characterized in that on the half hexagonal cover 2 hexagonal through hole 4 in half being arranged, each angle of hexagonal through hole 4 is 120 degree in half, the open slot 5 that hexagonal through hole 4 links in the part outside of half hexagonal cover has with half, have teeth groove 8 on two inclined working of hexagonal through hole 4 in half, the working end of handle 1 is by bearing pin 4, check ring 9 and half hexagonal cover link and are inserted in the open slot 5, and act on nut 7 or pipe 6 by two inclined working application of forces of half hexagonal through hole 4, the axle center with bearing pin 3 that is shaped as of the working end working face of handle 1 is the involute of generating circle, in half on the hexagonal symmetry axle of hexagonal through hole 4 short long down and with generating circle garden heart off-centre 1/2nd generating circle diameters.
