Positioning fastener of manual tool

Abstract

A locating fastener for fastening a manual tool (spanner) at a fixed position has a jointer with a locating slot which has at least one turn-stopping with a locating slot which has at least one turn-stopping part, and a fastener with at least one group of turn-stopping parts at its one end and at least one group of elastic fastening parts at its another end.

Description

Technical field: [0001] The invention relates to a hand tool positioning type clamping device. Background technique: [0002] At present, the structure of joints and hand tools has been developed very maturely, and many structures have been applied for patents, including: [0003] For example, China Taiwan No. 87210568 "Improvement of the Sleeve Locking Structure of the Ratchet Wrench", it is provided with a groove on the joint to cover an O-ring, by virtue of the elasticity of the O-ring The end surface opposite to the tool is stuck, the effect of such a structure is very limited, and the material of the O-ring is prone to adverse changes, hardening or becoming brittle, and the service life is limited; therefore, some operators change it to a C-shaped buckle However, it is a loose fit, so when the joint is connected to the tool, the C-shaped buckle is prone to improper displacement, so that the clamping with the tool cannot be positioned accurately, and it is difficult to ...

[0003] For example, China Taiwan No. 87210568 "Improvement of the Sleeve Locking Structure of the Ratchet Wrench", it is provided with a groove on the joint to cover an O-ring, by virtue of the elasticity of the O-ring The end surface opposite to the tool is stuck, the effect of such a structure is very limited, and the material of the O-ring is prone to adverse changes, hardening or becoming brittle, and the service life is limited; therefore, some operators change it to a C-shaped buckle However, it is a loose fit, so when the joint is connected to the tool, the C-shaped buckle is prone to improper displacement, so that the clamping with the tool cannot be positioned accurately, and it is difficult to achieve a high positioning effect. Purpose: Another company improves the structure of its simple C-shaped buckle, and improves the effect of locking and positioning with different shapes, among them, such as Taiwan, China No. 90220753 "Clamping Device for Tools (2) 』The new patent case, please refer to Figure 6, which is to clamp the two free ends of the fastener 90 on the slot 910 of the joint 91, and at least two inwardly retracted stoppers 900 are provided at the periphery And at least one protruding catch part 901, clamped against the draw-in groove 910 by the limit part 900, and the catch part 901 protrudes outside the draw-in groove 910; When the slot 910 is on, the locking member 90 will still rotate in the slot 910, which is not a fixed structure. Therefore, the position where the locking part 901 of the locking member 90 is exposed to the slot is uncertain, and it is locked at one point. When it is used, it will produce improper offset, so that its clamping cannot be kept in the most stable state, so it is necessary to improve
