Abstract

The utility model relates to a fastening tool which integrates an adjustable wrench, a solid wrench, a ring wrench and a grip wrench into a whole. The utility model is characterized in that the outer end of the head of a wrench lever is in an arc shape and is processed into a tooth shape, the thickness of the tongue of a toothed part is equal to the thickness of the head, and the tail part of the wrench lever is processed into quincuncial holes with 12 inner angles; every two adjacent inner edges of the head are crossed into an angle of 120 DEG which is formed by a certain proportion of length; the root of the head is of an open type. The wrench lever is connected with the head by a shaft pin, and an intelligent wrench of the utility model is formed. The purpose of rapidly fastening objects in various shapes, thickness and sizes can be realized because of the action of the physical commonality of straight lines and curves, and the tight matching of teeth.

Description

Intelligent spanner

The utility model be a kind ofly in same spanner, have plurality of specifications, purposes is the fastened tools of one.

The fastened tools of present domestic use all is the instrument of the special purpose of a handle one usefulness, and these traditional fastened tools exist function and singly go into to carry inconvenience, use dumb, shortcoming such as effect is low.

Providing a kind of adjustable wrench, fork spanner, double offset ring spanner, pipe vice of collecting at above-mentioned shortcoming the utility model in same spanner is the fastened tools of one, reach in conjunction with fast, spin is powerful, use continuously, simple and direct, easy to carry, the purpose that improves effect flexibly.

The structure of the utility model Intelligent spanner, by tommy bar (1), chieftain (2), pivot pin (3) is formed, and it is characterized in that:

1, tommy bar (1) is divided into head, middle part, afterbody three parts.(1) the head outer end is arc and is processed into the tooth shape, makes it and fastened (unclamping) when object combines, and can strengthen frictional force; Tooth portion tongue end thickness equates with chieftain (2) thickness, also can be in conjunction with self-locking when making it thin with fastened (unclamping) object; Be drilled with a hole on the inner portion plane, the usefulness that supplies chieftain (2) and tommy bar (1) that pivot pin (3) is installed when being connected.(2) cross section is a flat pattern in, and two planes all mark.(3) afterbody is processed into interior 12 jiaos of plum blossom holes, directly makes the usefulness of double offset ring spanner.

2, each adjacent inner edge of chieftain (2) intersects hexagonal angle, and is made of certain length ratio; Chieftain (2) root is an open type, can pack into the head of tommy bar (1) flexibly; Be drilled with a hole on the root plane, the usefulness that supplies chieftain (2) and tommy bar (1) that pivot pin (3) is installed when being connected.

3, tommy bar (1) is connected by pivot pin (3) with chieftain (2), promptly becomes the fast self-locking multifunctional wrench.Because the combination of the straight line of each inner edge of chieftain (2) and the arc curve of tommy bar (1) head and the effect of physics general character, and under the close fit of tommy bar (1) head tooth, fastened (unclamping) object whatsoever shape, thickness, size can both reach fastening rapidly (unclamping).

Adopt the utility model Intelligent spanner to have the following advantages:

The first, diverse in function, the while can be made the usefulness of adjustable wrench, fork spanner, double offset ring spanner, pipe vice in same spanner.

The second, use simple and direct fast, flexible, fastened (unclamping) object whatsoever shape, thickness, size all can closely cooperate by chieftain's (2) any activity and tommy bar (1) arc tooth, can fastening fast (unclamping).

The 3rd, adhesion is strong, torsion is big, because the combination and the effect of physics general character of each inner edge straight line of chieftain and tommy bar arc curve, and the closely cooperating of plate stem head tooth, as long as spanner is swing gently on fastened (unclamping) object, can self-locking, be difficult for skidding, significantly reduced the slip loss.

The 4th, easy to carry, improve effect, one has the function of adjustable wrench, fork spanner, double offset ring spanner, pipe vice simultaneously to spanner, improves the effect several times, carries more practical to railway, oil field, building, mine and go out repairing and cutfit especially.

Fig. 1 is the structure chart of the utility model Intelligent spanner, among the figure: 1, spanner, 2, the chieftain, 3, pivot pin.

Fig. 2 is the part drawing of the utility model Intelligent spanner tommy bar (1).

Fig. 3 is the part drawing of the utility model Intelligent spanner chieftain (2).

Claims

A kind of adjustable wrench, fork spanner, double offset ring spanner, pipe vice of collecting is the Intelligent spanner of one, by tommy bar (1), chieftain (2), pivot pin (3) is formed, it is characterized in that tommy bar (1) head outer end is arc and is processed into the tooth shape, tooth portion tongue end thickness equates with chieftain's thickness; Tommy bar (1) afterbody is processed into interior 12 jiaos of plum blossom holes; Each adjacent inner edge of chieftain (2) intersects hexagonal angle, and is made of certain length ratio; Chieftain (2) root is an open type, can pack into the head of tommy bar (1) flexibly; Intelligent spanner through tommy bar (1) with after chieftain (2) is connected by pivot pin (3).
