Description

Folding handle device

The invention relates to the technical field of a handle structure using a hand tool, in particular to a folding handle device that can be folded, unfolded, folded, and changed in different use states.

According to the press, T-wrenches are common hand tools on the market, such as the patent case of "T-type universal ratchet wrench" of the Republic of China Announcement No. M419652, and the patent case of "T-type socket wrench" of the Announcement No. M515448. A T-shaped handle has a shaft extending vertically, and the other end of the shaft is set as a driving part to provide a set of screws to be tightened and loosened, and the T-shaped handle protrudes laterally on both sides. The lever can be held by both hands, and it can stably form a large operating torque during tightening and loosening operations.

As mentioned above, the fixed T-shaped handle takes up too much space, which is not conducive to storage and carrying, which causes a lot of inconvenience in use. Therefore, the industry has introduced a structure that can be pivoted and used, such as the "Hexagon wrench type" of the Republic of China Announcement No. M317317. The "patent with multiple-use bending and telescoping structure" patent case is mainly used to articulate a articulated joint structure between the wrench body and the bent hexagonal receptacle socket.

However, although the above-mentioned conventional patent is a movable joint composed of a rivet between the wrench body and the plug seat, although it can be unfolded and collapsed through angular pivoting, the pivot between the wrench body and the plug seat is vertically opened. When the state provides the driving screw, the lack of a limit between the wrench body and the plug seat makes it easy for the wrench body to be biased during a large force operation. The pendulum not only causes the operating force to be scattered but cannot effectively tighten or loosen the screw, which is the biggest disadvantage in the use of the above-mentioned conventional patents.

Therefore, how to deal with the above-mentioned conventional patent structure, because the wrench body and the plug seat are unfolded and pivoted in a vertical state of use, the wrench body is easily prone to deflection during a large force operation, which is impossible. Innovative inventions, such as effectively tightening or loosening screws, are the difficult points to be solved by the present invention.

The main object of the present invention is to fix the grip limit of the pivoting operation handle in a T-shaped state with an angle between the handle, and to firmly support the handle to withstand the large torsional force of the two-hand operation without deflection.
