Hand tool power post grip positioning structure improvement

This creation is related to a technical field related to hand tools, and in particular to the improvement of the positioning structure of a power tool grip of a hand tool that can be turned.

According to the conventional tool structure of the screwdriver head and the sleeve, the two ends of the axially extending shank are respectively provided with a handle and a tool head, so that the user can hold the handle and interlock the workpiece to lock the workpiece. .

The above-mentioned conventional tools cannot change the holding and driving angles, and cannot extend into a narrow space with an angle, thereby limiting the environment and occasions for implementation. In the engine room of a car, the space of the engine room is narrow, and some of the workpieces are covered by other parts, so that it cannot be screwed with a conventional tool.

To this end, some practitioners have proposed a number of solution plans, such as the Chinese patent No. M431781, through the first and second ends of the right angle, respectively connected to the power source and the tool head, providing users with the ability to operate in a small space. However, the prior case assists the messenger to lift the grip of the body. Due to the poor design of the structure, the following problems exist: When the handle of the prior case is to be adjusted, it is necessary to turn the handle into a storage state before twisting the handle, in addition to causing the inconvenience of twisting the force, It is contrary to the implementation of the operation.

When the handle is to be adjusted, most of them are adjusted during the operation because the user feels uncomfortable or environmentally restricted; if the structure is operated according to the conventional structure, the user must stop the operation first and support the body with one hand. Next, after the handle is folded, the handle can be twisted and adjusted, which not only causes the burden on the user's hand, but also affects the smooth operation process.

In view of the above problems and deficiencies in the prior art, one of the purposes of the present invention is to overcome the lack of conventional handle handling by the design of the transmission structure.

In order to achieve the above object, the present invention proposes an improved positioning structure of a power tool grip of a hand tool having two first and second ends in a right angle shape; wherein the first end shaft is coupled with a multi-angle rod and A bushing. The handle positioning structure comprises: a plurality of positioning holes, a ring seat, a pivoting member, an elastic member, and a handle. The positioning holes are arranged outside the sleeve. The ring seat is rotatably sleeved on the outer circumference of the sleeve and abuts against the first end, and has a shaft hole, a side hole, and a channel. The pivoting member includes a threaded rod and a tongue that are pivotally connected to each other, and a wing portion formed on the outer side of the tongue. The tongue and the elastic member are coupled to the second limiting ring to be received in the side through hole. By the composition of the upper member, the handle linkage pivoting member selectively penetrates one of the positioning holes, so that the ring seat can be rotated or positioned along the sleeve, and the handle can be turned to be close to the sleeve through the pivoting member. Or at right angles to the bushing.
