Abstract
The utility model discloses a labor-saving wrench which belongs to tools and mainly solves the problem that the effects of easy carrying and convenient operation of the existing wrench can not be achieved simultaneously. The labor-saving wrench structurally comprises a wrench head and a handle, wherein the tail end of the wrench head is provided with a connecting rod; the tail end of the connecting rod is provided with a protruding column; the interior of the handle is provided with a hollow cavity; one end of the handle is provided with a through hole; and the connecting rod passes through the through hole to be slidably arranged in the cavity of the handle. For the wrench, the connecting rod and the handle are in slip connection, in the carrying process, the connecting rod is retracted into the handle to reduce the overall volume of the wrench, thus being convenient for carrying; and in the using process, the connecting rod is pulled out of the handle to increase the arm of force acting on the wrench in the operation process, thus reducing the force exerted by a user and achieving the aim of being portable and easy in use.
Description
Technical field
The utility model relates to a kind of instrument, specifically a kind of spanner.
Background technology
Spanner is one of instrument commonly used in the assembling bolt process, but fixing during present pinch bar, and the wrench operated of long handle is laborsaving but carry inconvenience, but needs bigger strength during the operation easy to carry of the spanner of short handle, makes troubles to the user.
The utility model content
The purpose of this utility model is to provide a kind of labour-saving spanner, mainly solves spanner and is easy to carry about with one and operates the light problem that can not take into account simultaneously, and this labour-saving spanner adopts telescoping handle to take into account portable and labour-saving characteristics.
The technical scheme in the invention for solving the technical problem is: a kind of labour-saving spanner, its structure comprises driving end and handle, the end of described driving end is provided with a connecting rod, described connecting rod end is provided with a projection, described handle is inner for a cavity and an end are provided with through hole, and described connecting rod passes in the inner chamber that through hole is slidingly arranged in handle.
The beneficial effects of the utility model are: because connecting rod and handle are slidingly connected, when carrying, in connecting rod retraction handle, reduce the volume of spanner integral body, be easy to carry, during use, connecting rod is pulled out from handle, increase the arm of force that affacts in the operating process on the spanner, thereby alleviate user's applied force amount, reach light easy-to-use purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 driving end, 2 connecting rods, 3 projections, 4 handles.
The specific embodiment
As shown in Figure 1.A kind of labour-saving spanner, its structure comprises driving end 1 and handle 4, the end of described driving end 1 is provided with a connecting rod 2, described connecting rod 2 ends are provided with a projection 3, described handle 4 inside are provided with through hole for a cavity and an end, described connecting rod 2 passes in the inner chamber that through hole is slidingly arranged in handle 4, the projection 3 of connecting rod 2 ends can limiting rod the outer length of 2 draw-out handles 4, avoid connecting rod 2 to deviate from handle 4 and cause operating hidden danger.
When carrying, in connecting rod 2 retraction handles 4, reduce the volume of spanner integral body, be easy to carry, during use, connecting rod 2 pulled out from handle 4, increase the arm of force that affacts in the operating process on the spanner, thereby alleviate user's applied force amount, reach light easy-to-use purpose.
