Abstract

The utility model belongs to hand-operated tools field, and in particular to and it is a kind of easy to carry, dismount the tubular type fission cross like spanner of specification multiplicity.It is characterized in that: original integrated cross like spanner is divided into four parts, the respectively collet head of tube body, hexagonal extension bar, square tenon connector, different size by the way of combination, when use together by four component combinations.It is easy to carry with occupying little space, a advantages of spanner can be suitably used for the dismounting environment of specification multiplicity.

Description

Tubular type fission cross like spanner

Technical field

The design be cannot replace, cannot dismantle based on traditional cross like spanner, not Portable belt the disadvantages of, the innovation of progress changes Into design.

Background technique

Currently, traditional cross like spanner occupied space very much not Portable belt, at most there are four the sets of specification for a cross like spanner Cylinder size is unable to satisfy the dismounting environment of multi-specification, and the technical team of Xinda Tools Co., Ltd., Longkou City is by for many years Research and discovery propose the concept of tubular type fission cross like spanner.

Utility model content

The purpose of the design is that so that cross like spanner is occupied little space easy to carry, and a spanner can be suitably used for multi-specification Dismounting environment.

The technical solution of the design: according to traditional cross like spanner there are the shortcomings that, the design using combination by the way of, will be former The integrated cross like spanner come is divided into four parts, the respectively collet head of tube body, hexagonal extension bar, square tenon connector, different size.It uses When by four component combinations together.

By above scheme, may be implemented:

1, space can be saved, it is easy to carry；

2, collet head (different size) is replaceable, and use scope is extensive；

3, easy to operate, torsion increases, more labor-saving；

4, spanner structure is innovated, simply, novel；

5, new technical thought and theoretical foundation are provided for the structure design of later tool wrench.

Detailed description of the invention

The technical solution of the utility model is described in further details below in conjunction with drawings and specific embodiments.

Specific embodiment

Referring to attached drawing 1, the assembling sequence of the design is: combining hexagonal extension bar with tube body (be inserted into hexagonal extension bar first In tube body hexagonal through-hole, it is located at tube body between two adjacent steel balls of hexagonal extension bar, prevents it from the play on hexagonal extension bar), Secondly square tenon connector is installed in hexagonal extension bar bottom end, finally the installation sleeve head on square tenon connector.

Referring to attached drawing 2, the structure of hexagonal extension bar: being drilled with counterbore on hexagonal extension bar, and spring and steel are housed inside counterbore Ball, effect are for positioning tube body and fixed square tenon connector.Hexagonal extension bar socket end external process has hexagon, in hexagon On be drilled with counterbore, inside counterbore be equipped with spring and steel ball, effect be with tube body cooperation achieve the effect that storage.

Referring to attached drawing 3, the structure of tube body: tube body both ends and centre are machined with hexagonal through-hole respectively, and the purpose is to provide not With torsion, the punching of tube body both ends has six square sockets, tubular body be it is hollow, for storing hexagonal extension bar.

Referring to attached drawing 4, the structure of square tenon connector: one end is Hexagonal jacket, and effect is connection hexagonal extension bar；The other end is Square head (is drilled with counterbore, equipped with spring and steel ball inside counterbore) in square head, and effect is installation sleeve head.

Referring to attached drawing 5, the structure of collet head: one end is Hexagonal jacket, and effect is for dismantling hex nut；The other end Spherical groove is machined with for four square sockets and on its inner wall, effect is connection side's joggle.

Referring to attached drawing 6, when storage, by hexagonal extension bar insertion tube body, hexagonal extension bar socket end and six square set of tubular body Cylinder cooperation, to achieve the effect that storage.
