Abstract

The utility model provides a long-acting clamping device of a tooth cleaning machine handle torque wrench, the magnet is used as the clamping device of the clamp working tip. The magnet can be made into a circular ring shape, a square sheet shape or other shapes, a circular ring-shaped magnet is mounted in a circular ring groove provided by a mandrel, or the magnet is mounted on two ends or the middle part of the outer circle on the mandrel. Proved by the experiment, the utility model can not be ineffective for clamping more than 3000 times by adopting the magnet as the clamping device of the clamp working tip, the service life of the torque wrench is greatly improved, and the assembling is convenient.

Description

The long-acting clamping device of tooth cleaner handgrip torque wrench

Technical field

This utility model relates to the long-acting clamping device of the torque wrench that tightens and back-out, the especially torque wrench of the point of working on a kind of tooth cleaner handgrip.

Background technology

The maximum disadvantage of the sharp torque wrench that tightens and back-out of working on the tooth cleaner handgrip of present domestic use is to use short problem of life-span, the main cause that causes this problem is because of torque wrench in the course of the work, because of the clamping device on the spanner is to utilize the elasticity of jump ring to come clamping work point, when jump ring is weakened until jump ring generation plastic deformation by elasticity after the clamping repeatedly; That is to say that the number of times that utilizes jump ring to come clamping work point is very limited, the number of times that one of at present domestic best torque wrench can clamping only is 400 times, and service life is short.

The utility model content

The purpose of this utility model is a kind of long-acting clamping device that can repeatedly tighten or back-out the work point of design, and the clamping number of times did not nearly lose efficacy more than 3000 times, improves service life.

Architectural feature is: the clamping device of making clamping work point with Magnet.

This Magnet can be made circular, square lamellar or other shape.

Mounting circular ring shape Magnet in the ring groove that mandrel is established; Or Magnet is installed in the two ends or the centre of the cylindrical on the mandrel.

Through experiment showed, that this utility model utilizes Magnet to make the clamping device of clamping work point, the clamping number of times did not nearly lose efficacy more than 3000 times.The torque wrench life-span improves greatly, and easy to assembly.

Among the figure: 1, Magnet, 2, mandrel, the cylindrical recess on the scrobicular ring on 2-1, the mandrel, 2-2, the mandrel, the cylindrical on 2-3, the mandrel, 3, spring, 4, steel ball, 5, the spanner loam cake, the screw of 5-1, spanner loam cake, the bar of 5-2 spanner loam cake hole, 6, the spanner bottom, 7, screw.

The specific embodiment

High-grade torque wrench assembly relation is as follows: be equipped with four springs 3 on four bar hole 5-2 of spanner loam cake 5; Mounting circular ring shape Magnet 1 in the ring groove 2-1 that mandrel 2 is established; Mandrel 2 is assemblied on the position, hole at spanner loam cake 5 centers; Four steel balls 4 are assemblied in respectively between the cylindrical recess 2-2 on spring 3 and the mandrel 2; Spanner bottom 6 is locked on the spanner loam cake 5 by four screws 7.

Shown in the figure a kind of embodiment of the present utility model.Utilize Magnet to make the device of clamping work point, this Magnet can be made circular, square lamellar or other shape.This Magnet can be installed on the scrobicular ring 2-1 of mandrel, also can be installed in two ends or the centre of the cylindrical 2-3 on the mandrel.

The difference of common torque wrench and high-grade torque wrench be the limit power structure of using different, but all be to utilize the magnetic of Magnet to realize for the clamping device of work point.The long-acting clamping device of this tooth cleaner handgrip torque wrench comprises and is used for high-grade torque wrench and common torque wrench.
