Problems solved by technology

It is inconvenient to carry and replace during actual operation. At the same time, due to the wide variety of wrenches, it is not convenient to store and manage. The variety of wrenches also causes a waste of resources.
[0003] In order to improve labor productivity, an adjustable wrench is commonly used now, the opening width of which can be adjusted within a certain range, and is locked and fixed by adjusting the screw rod. When in use, it is necessary to align the workpiece and then clamp and fix it, which greatly reduces the Production efficiency cannot meet the existing fast-paced production needs

Abstract

The invention discloses a clamp type wrench which comprises a main clamp handle and an auxiliary clamp handle and further comprises a wrench body, a fixed clamping part, a movable clamping part and an elastic part. The main clamp handle and the auxiliary clamp handle are hinged to each other in a crossed manner. The wrench body is fixedly arranged at the end portion of the main clamp handle. The fixed clamping part is fixedly arranged on the wrench body. A sliding groove is formed in the wrench body. The end portion of the auxiliary clamp handle is rotationally connected with the movable clamping part and drives the movable clamping part to slide in the sliding groove. An elastic part installation groove parallel to the sliding groove is formed in the wrench body. The elastic part is arranged in the elastic part installation groove. The elastic part abuts against the movable clamping part. The clamp type wrench is convenient to use, capable of automatically clamping workpieces and capable of automatically adjusting the size.

Description

technical field [0001] The invention relates to the field of hardware wrenches, in particular to a clamp type wrench. Background technique [0002] In the machinery and equipment manufacturing industry, solid wrenches are simple, durable and indispensable. However, in the production activities under the modern lean management mode with production rhythm requirements, the disadvantages of its "dull head" gradually emerged. It is inconvenient to carry and replace during actual operation. At the same time, because the size of the wrench is various and it is not convenient to store and manage, the variety of wrenches also causes a waste of resources. [0003] In order to improve labor productivity, an adjustable wrench is commonly used now, the opening width of which can be adjusted within a certain range, and is locked and fixed by adjusting the screw rod. When in use, it is necessary to align the workpiece and then clamp and fix it, which greatly reduces the Production effic...
