Description

Folding tool set

The present invention relates to hand tools and, in particular, to a folding tool set having a designer that can adjust the tightness of the tool.

According to the folding tool set, which is designed to be convenient to carry and has a plurality of tools, usually has a casing and a plurality of tools pivoted in the casing, and the plurality of tools are respectively pivoted to the casing by two shafts (for example, bolts). The two ends allow the tool to be pulled out or folded into the housing to save volume. The tools of the folding tool set will rotate frequently, and after a period of use, the tools are easily loosened by wear. In the case of a conventional folding tool set, the head of the bolt is exposed to the housing, and once the tool is loose, the tool can be tightened only by tightening the bolt, so that the tool is loose for the conventional folding tool set. The problem can be solved.

However, under the aesthetic requirements, the current folding tool set is designed to hide the head of the bolt so that the bolt is not exposed. In this design, the user cannot adjust the tool when the tool is loose.

In order to solve the above problem, the inventor has proposed a new patent of "the body of the folding tool set" No. 094207493, which has the structure as shown in the first figure, and has two side plates (11) (12) and two pivots (15). The two side plates are respectively provided with a first screw hole (13) and a second screw hole (14) on the inner side of the same end, and the threads of the first and second screw holes are reversed; the rods of each pivot rod (15) A driving portion (16) is fixed on the body for rotating the pivot rod, and a screw portion (17) (18) is respectively disposed at two ends thereof, and the two screw portions (17) (18) are reverse threaded teeth. . When the folding tool set is assembled, a plurality of tools (19) are firstly threaded on the pivots (15), and then the screw portions (17) (18) of the two ends of the pivot rods are respectively screwed to the two side plates (11).
