Problems solved by technology

The ring wrench uses the geometric constraints between its inner contour and the threaded fasteners to realize the assembly operation. Sometimes due to the limitation of the operating space, after a certain angle of rotation, the wrench needs to be removed and then re-inserted on the threaded fasteners and rotated until it is completed. The whole assembly, work efficiency is not high

Embodiment Construction

[0022] Since the threaded fastener is a symmetrical structure, the matching relationship between the wrench and the threaded fastener changes periodically, and a cycle is used to describe it.

[0023] Such as Figure 1A and Figure 1B As shown, the returnable fully flexible wrench used in a narrow operating space includes a handle 1 and a wrench head 7, and the handle 1 and the wrench head 7 are connected as one; wherein the wrench head 7 is divided into two parts by the opening 3 and the flexible hinge 2, and one part is The superior arc part 5 of the wrench head, the other part is the inferior arc part 6 of the wrench head, one end of the superior arc part 5 of the wrench head is connected to the inferior arc part 6 of the wrench head through the opening 3, and the other end of the superior arc part 5 of the wrench head is formed by a flexible The hinge 2 connects the inferior arc portion 6 of the wrench head.

[0024] The inner ring of the wrench head 7 is composed of a he...

Abstract

The invention relates to a returnable fully-compliant spanner used for narrow operation space and a method. The fully-compliant spanner comprises a handle and a spanner head which are connected integrally, the spanner head is divided into two parts by an opening and a flexible hinge, one part is the major arc part of the spanner head, and the other part is the minor arc part of the spanner. One end of the major arc part of the spanner head is connected with the minor arc part of the spanner head via the opening, and the other end of the major arc part is connected with the minor arc part of the spanner head by the flexible hinge. The returnable fully-compliant spanner has the advantages of simple structure, low manufacturing cost and applicability to narrow operation space.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, and relates to a returnable fully flexible wrench used in a narrow operating space and a realization method. Background technique [0002] The wrench is an important tool in the mechanical assembly process, and now there are ring wrenches, ratchet wrenches, etc. that are commonly used. The ring wrench uses the geometric constraints between its inner contour and the threaded fasteners to realize the assembly operation. Sometimes due to the limitation of the operating space, after a certain angle of rotation, the wrench needs to be removed and then re-inserted on the threaded fasteners and rotated until it is completed. The whole assembly, work efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to provide a fully flexible wrench with a simple structure, low cost, suitable for narrow operating spaces and a method for realizing it. [0004] The te...
