Abstract
The utility model discloses a labor-saving pliers, which comprises a handle (1) and a gripper jaw (2) actively connected through a pin shaft (4) by a connection plate (3). The utility model is characterized in that: the upper end face of the handle (1) and the lower end face of the gripper jaw (2) are provided with two gears (5) meshed with and contacting with each other. The utility model adopts gear meshing and rolling contact mode, thereby greatly reducing friction force and no longer needing assist of spring so as to avoid resistance of spring and simplify structure; moreover, the utility model is uneasy to damage and has long service life.
Description
Affiliated technical field
The utility model belongs to a kind of manual hardware ﹠ tools, is a kind of pliers particularly.
Background technology
In the prior art, pliers generally all comprises handle and jaw, is provided with rotational structure between handle and jaw, controls the jaw clamping, clamps or cut off object by operating grip.Use for convenient, improve the effectiveness of pliers, now occurred laborsaving pliers.On May 11st, 2005 State Intellectual Property Office's Granted publication a utility model patent " double lever labor-saving plier ", Granted publication number is: CN2698523Y, the patent No. is: 200420017535.1.This patented technology includes: handle and jaw is characterized in that: be provided with connection open-work and bandy elbow in the inner end of handle, be provided with the connection open-work and the aduncate arc arm of force in the inner end of jaw; The open-work of the inner end of two handles and jaw is provided with the square frame plate that is connected open-work with four jiaos and connects by bolt is movable, and handle two elbows contact with jaw two arc arm of force opposed inside respectively.Between the inboard of the two arc arm of forces, be connected with spring.Although the principle that it adopts lever has the labour-saving effect, also there is following deficiency: when implementing the operation of clamping lever, overcome the resistance of spring and the force of sliding friction between handle two elbows and the jaw two arc arm of forces.In addition, spring is fragile, often keep in repair or change, and has brought inconvenience to the user.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved labor-saving plier is provided, and its compact conformation is reasonable, and is easy to use laborsaving, not fragile.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: handle and jaw, handle and jaw are connected by bearing pin is movable by gusset piece, and it is characterized in that: the upper surface of handle and the lower surface of jaw are provided with the gear teeth, and connection is touched in the two engagement.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, open handle, jaw is opened under the effect of the engagement gear teeth thereupon; During clamping, merge handle, jaw also merges thereupon.It adopts gear teeth meshing to roll and touches the connection mode, has reduced frictional force greatly, and it is auxiliary also to need not spring, has both avoided the resistance of spring, also simplifies the structure.The utility model is not fragile, long service life.
