Description

A kind of cross like spanner

Technical field

The utility model relates to spanner technical fields, specifically be a kind of cross like spanner.

Background technique

Cross like spanner in the prior art generally as in patent No. CN201520307156, pull by a kind of slidingtype cross Hand, including matrix and be arranged on the matrix be in cross distribution first body of rod and second body of rod, matrix be equipped with spring with Keep first body of rod and the second body of rod position relatively fixed, in above-mentioned patent, first body of rod and second body of rod can be moved, and be realized Adjust arm strength function, however, matrix be it is solid, thus have the disadvantage that the structure of entity makes materials'use mistake More, waste of resource, in addition, the material of matrix is usually steel material, if entity, quality is larger, it has not been convenient to using with remove Fortune.

Therefore, hollow structure matrix be badly in need of design, however, in above-mentioned patent the other components such as its spring mounting structure It is solid that be based on matrix be, is not suitable for hollow structure, if being arranged to the matrix of hollow structure, needs corresponding design flexibility part Equal mounting structures.This case comes therefrom.

Utility model content

Technical problem to be solved in the utility model is that at least to provide a kind of quality relatively light and sliding in the body of rod It can be with relatively-stationary cross like spanner after dynamic.

In order to solve the above technical problems, a kind of cross like spanner of the utility model, including

Mounting base,

Two bodies of rod, two bodies of rod are threaded through in mounting base to be slidably connected with mounting base；

At least one mounting hole of mounting base；

Mounting base be it is hollow, there is interval between two bodies of rod and the inner sidewall of mounting base, be fixed with peace in mounting hole Fill block, mounting blocks are extended with supporting part towards the wherein body of rod, and supporting part is located in interval, be equipped in supporting part for wherein A piece body of rod surface is pushed against to form the damping structure of damping force.

After adopting the above structure, it at least has the advantages that

1. mounting base be it is hollow, between two bodies of rod and the inner sidewall of mounting base have interval, so as to effectively subtract The use of few material, economizes on resources, and hollow structure is lighter compared to solid architecture quality, is conducive to carry and use, peace Dress seat material is generally steel material, still ensure that structural strength under hollow structure.
