Tool head positioning structure of head shaking wrench

Abstract

The invention discloses a tool head positioning structure of a head shaking wrench. A clamping part which is close to or far away from a tool head under the control of rotation of a control part is arranged between a wrench handle and the tool head; the control part keeps at position after a user wrenches the tool head by two continuous faces with different depths on the control part, namely a pushing part and a retreating part, and an elastic positioning group positioning the control part; and the pushing part or the retreating part on the control part is opposite to the clamping part, so that the clamping part contacts and positions the tool head relative to an end part of the tool head or can swing without contacting the tool head, and the tool head can be positioned quickly and stably.

Description

Technical field [0001] The invention relates to a shaking head wrench, in particular to a tool head positioning structure of the shaking head wrench. Background technique [0002] The current shaking head wrench is suitable for a tool head that can be pivoted at the end of the handle body of the tool, commonly known as shaking head. The most traditional form is a simple pivotal combination between the handle and the tool head. There is no structure to fix the positioning of the tool head, so when the wrench is used, the tool head cannot be positioned reliably. When the workpiece is pulled, the tool head in the free shaking form will have the disadvantage of improper swinging, so improvement is necessary Therefore, some manufacturers have provided a tooth-like structure at the outer periphery of the pivot joint of the tool head, and an elastic clamping structure in which the elastic member pushes the steel ball at the relative position of the handle end. The elastic clamping struc...

Problems solved by technology

[0004] 1. The stability is limited: since the top block 72 stops on the inclined surface 710, when receiving a slightly larger pushback force, following the guiding direction of the inclined surface 710, the control rod 71 will produce an unnecessary Backlash force, so that the state of the elastic clamping of the control rod 71 cannot be effectively maintained, that is, the control rod 71 will have a component force of displacement, and has the disadvantage of improper movement, making it difficult to maintain the control rod 71 On the position of pushing away this jack block 72 and positioning this tool head 90 angles, so there is a need for improvement

[0005] 2. Finger pressing does not meet the convenience requirements of use: since the protruding direction of the control rod 71 is on the side of the overall wrench in the horizontal direction, the user must press sideways to control whether the tool head 90 is positioned or not. It is a new way of use, and it is difficult to confirm whether the pressing is confirmed or not, so there is a need for improvement

[0006] It can be seen that the current common shaking head wrench may not be able to locate, or the positioning is not accurate, or there must be other operating methods for positioning.
