Abstract

The utility model discloses a wrench, and belongs to the technical field of the wrench. The wrench consists of a hole, a movable screw, a scale and a handle, and is characterized in that the head part of the wrench is provided with convex-concave scale lines. When the wrench is used, the tail hole of the wrench hanged on a tool table is taken out from the hook; the handle is held by hand; the movable screw is screwed to sleeve the wrench head into a screw cap or a bolt; and the convex-concave scale lines are observed. If the specifications of the screw cap or the bolt conform to the wrench, the operation can be performed; otherwise, the wrench is replaced. The utility model has the advantages of simple design, easy operation and high practicality in the operation and use on the sophisticated equipment and the liquid chlorine cylinder.

Description

A kind of spanner

Technical field

The utility model relates to a kind of spanner, especially relates to a kind of spanner that the length scale is arranged, and belongs to the spanner technical field.

Background technology

At present, the spanner of known technology does not have the length scale to mark at head, in the apprentice uses, the size of meeting coping screw is differentiated unclear and is caused and adopt the spanner model not right, it is very big to cause damage in some precision equipments, before the utility model is not made, does not have the spanner that the length scale is arranged and uses.

Summary of the invention

In order to overcome the deficiency of not having the spanner that the length scale is arranged in the prior art, the purpose of this utility model is for a kind of spanner that the length scale is arranged is provided, in this spanner precision equipment during dismounting construction bolt nut, can very measure the size of bolt nut accurately, and the spanner of decision in using whether rationally and the application of force whether even.

The technical scheme in the invention for solving the technical problem is: by hole, screw screw, movable screw, scale, handle and form, it is characterized in that Wrench head leaves the graduation mark of convex-concave shape, can be earlier in the use hanging over spanner afterbody hole on the tool stand from linking up with taking-up, hold handle, the turn movable screw is inserted in driving end in nut or the bolt, after seeing the graduation mark of its convex-concave shape,, can operate if nut or bolt specification conform to the utility model spanner; If be not inconsistent, then change spanner.

The beneficial effects of the utility model are simplicity of design, and are easy to operate, to manipulating on the precision equipment, use its practicality bigger on liquid chlorine cylinder.
