Integrated wrench structure preventing implementation workpiece from breaking away

Abstract

The invention provides an integrated wrench structure preventing an implementation workpiece from breaking away. The integrated wrench structure comprises a wrench head which is provided with a hollow operation containing space; an operation face is arranged on the peripheral wall of the operation containing space, a top end part is arranged above the wrench head and annularly protrudes and extends to the center of the operation containing space to form a top end protrusion, and the top end protrusion extends to the center of the operation containing space to form an inwards-protruding abutting ring space above the operation containing space; and the top end protrusion serves as a shielding limiting part above the operation containing space, and the top end protrusion is molded by the wrench head in an integrated extending manner. In this way, through simple constituting and arrangement, a wrench is prevented from breaking away from the implementation workpiece during operation, and the good processing convenience and the good economic benefit on manufacturing and assembling are further achieved.

Description

technical field [0001] The invention relates to a wrench structure, in particular to an integrated wrench structure which is convenient for assembly and has manufacturing economic benefits and prevents the workpiece from being separated. Background technique [0002] Wrench is a tool commonly used in fortification operations. It is used to tighten and loosen screws or nuts and other positioning workpieces. There are many types of wrenches, including open-end wrenches, compound wrenches, ring wrenches, adjustable wrenches and socket wrenches. etc., the existing wrench structure usually includes a head and a handle, and the head has an accommodating space for accommodating the workpiece (screw or nut), and by virtue of the accommodating space and the accommodating workpiece After the contact fit, the handle is rotated and applied to achieve the purpose of tightening and loosening the workpiece. Although the existing wrench structure technology can rely on the wrench to rotate...

This prior art (Chinese Taiwan No. 494830) is when the ratchet wrench forward (reverse) rotation operation, although can carry out clamping to the threaded part by means of the upper (lower) ring to prevent falling off with the wrench, but this The setting of the ring groove at the end of the receiving hole of the ratchet wrench and the combined use of the two upper and lower rings also have complicated components and inconvenience in manufacturing and assembling, which does not meet the economic benefits of manufacturing, and the embedded end of the ring is rotated by the wrench. It is easy to be deformed or squeezed and retracted during force operation, forming a serious defect in the appearance of the overall wrench, and it is also necessary to improve it; Important Issues That Wise Taxi Should Solve and Overcome

[0005] Therefore, in view of the shortcomings of the existing anti-separation wrench in its manufacture and assembly and the unsatisfactory fact in its structural design, the inventor of this case started to develop its solution, hoping to develop a more stable operation. An integrated wrench structure that prevents the work piece from detaching due to its high performance, safety and economic benefits, in order to serve the public and promote the development of this industry, and after a long time of conception, the present invention came into being
