Problems solved by technology
However, the existing technology uses multi-teeth meshing to fix the angle of the insert. Therefore, it is necessary to have high-precision teeth to achieve stable meshing between the teeth and the teeth of the insert. Otherwise, it will also occur when fixing. The gap causes the instability of the fixed state
In this way, there are disadvantages of high processing cost and time-consuming
In addition, when the wrench is operated, the teeth of the meshing part and the insert will be subject to a large force due to the torque of the action and the force direction of the user operating the wrench, resulting in wear and tear of the teeth after long-term use

Provided is a tool meshing device. The tool meshing device comprises a holding rod, a clamping and braking set, an action head and a pivot rod, wherein the holding rod is provided with a pivot groove, a braking groove is inwardly formed in the groove bottom of the pivot groove in a concave mode, a containing groove is formed in the outer side of the holding rod and is communicated with the braking groove, the clamping and braking set comprises an adjusting control rod, an ejecting brake rod and a cross elastic piece, the ejecting brake rod is arranged in the braking groove in a sliding mode and is provided with a meshing head section and a body section, the meshing head section is provided with a tooth groove, the action head is provided with a pivot swinging section which is arranged in the pivot groove in a pivot mode, the pivot rod penetrates through the pivot groove and the pivot swinging section, the tail end of the pivot swinging section is in an arc shape and is provided with a plurality of ratchet blocks, the adjusting control rod is arranged in the containing groove in a sliding mode, a groove is formed in the position, facing the braking groove, of the adjusting control rod, the adjusting control rod is sleeved with the cross elastic piece, and the two ends of the cross elastic piece abut against the containing groove and the adjusting control rod in an elastic mode. The frequency of occurrence of abrasion to the tooth portion is reduced, a working head and the holding rod can be firmly located by an angle, and the effect of firm locating is achieved with low manufacturing cost.
Description
Technical field [0001] The invention is a tool engagement device, in particular to a design that allows the user to adjust the working head to an appropriate angle to facilitate operation. Background technique [0002] Wrench tools are widely used to tighten and loosen screws, so as to assemble or disassemble parts of various industries. The finished parts and components of various industries range from household appliances to precision instruments. Therefore, the process of operating wrench tools will be limited due to the position and space of the operation, causing users to be unable to operate the wrench tools reliably and provide appropriate torque to Tighten or loosen the screws. [0003] In order to overcome the limitation of space and increase the convenience for the user to apply force, the related industry has improved the traditional one-piece wrench tool into a structure in which the working head can adjust the angle relative to the grip. Please refer to Taiwan Patent...
