Description

Pivoting tool that eliminates gaps

The present invention mainly discloses a tool, in particular a pivot tool capable of eliminating gaps.

Please refer to the patent case of "Tool Rotation Control Device" of Taiwan Patent No. I367807, which is a tool rotation control structure, which is arranged between a handle and a tool head, wherein: one end of the handle is formed into two parallel and opposite assembly parts, and the two assembly parts are respectively provided with a first through hole, and the inner edge of each first through hole is provided with a plurality of first ratchets, and the inner edge of each first through hole near the outer side is further provided with an annular groove; one end of the tool head is a working end, and the other end is provided with a second through hole, and the inner edge of the second through hole is provided with a plurality of second ratchets, and the tool head has the second through hole. One end is inserted between the two assembly parts of the handle, and the second through hole of the tool head is connected to the two first through holes of the handle; and the rotation control device includes: two ratchets, each ratchet has a plurality of ratchets on the outer edge, the two ratchets are respectively accommodated in the first through holes of the assembly parts of the handle, and the ratchet parts of the ratchets are engaged with the first ratchets of the handle, and part of the ratchets are engaged with the second ratchets of the tool head; a spring is arranged between the two ratchets, and the two ends of the spring respectively press against the two ratchets; and two C-shaped buckles are respectively accommodated in the annular grooves of the assembly parts of the handle.

However, in order for the handle and the tool head to smoothly pivot relative to each other, the two must be matched with a sufficient tolerance gap to reduce friction. As a result, after the user presses the two ratchets to disengage the handle, there is no hardware structure between the handle and the tool head to limit the relative position of the two. The tool head will shake relative to the handle, affecting the user's operating feel and being unable to stably control the pivot angle of the tool head relative to the handle.

In view of the defects of the above-mentioned known structures, the inventors have designed a pivot tool capable of eliminating the gap, which can overcome all the shortcomings of the above-mentioned known structures.
