Description

Folding handle device

Technical Field

The invention relates to the technical field of handle structures used by hand tools, in particular to a folding handle device which can be folded, unfolded, folded and changed into different using states.

Background

T-type wrench is a common hand tool in the market, such as the "T-type universal ratchet wrench" of taiwan publication No. M419652, and the "T-type socket wrench" of publication No. M515448, and the like, which generally has a T-shaped handle having a vertically extending shaft, and a driving portion is provided at the other end of the shaft end to provide a screw member to be fastened and unfastened, and a transverse rod protruding from both sides of the T-shaped handle can be held by both hands, so that a large operation torque can be stably formed during the fastening and unfastening operations.

The above-mentioned fixed T-shaped handle occupies too much space to be convenient for storage and carrying, which causes inconvenience in use, and therefore, some manufacturers have proposed a structure capable of being used in a movable pivoting manner, such as taiwan patent publication No. M317317, "hexagonal wrench type structure with multiple replaceable folding and telescopic sleeves", which is mainly characterized in that a wrench body and a folding hexagonal receiving plug seat are connected by rivets to form a movable joint structure.

However, although the above-mentioned prior art patent uses the movable joint formed by the rivet between the wrench body and the plug seat to be able to be unfolded and folded by angular pivoting, when the wrench body and the plug seat are unfolded and pivoted to be perpendicular to each other to provide a driving screw for use, because there is no limit between the wrench body and the plug seat, the wrench body is easily deviated during operation with a large force, which not only disperses the operating force and cannot effectively tighten or loosen the screw, but also is the greatest disadvantage in the above-mentioned prior art patent.

Therefore, how to innovate the present invention is to overcome the disadvantages that the existing patent structure lacks a limit when the wrench body and the plug seat are unfolded and pivoted to a vertical state for use, so that the wrench body is easy to generate deflection during operation of large force application, and the screw cannot be effectively tightened or loosened.
