[0002] Tongs is the tool of clamping solid object, is often seen in rural family daily life cooking and when adding firewood in winter, when outdoor barbecue, also is seen in clamping shrimp, crab, eel, loach, coal or honeycomb coal which is not convenient to catch by hand, now street sweeper also uses it to pick up ground garbage, pick up small objects in small hole or gap etc. One end of the traditional tongs is used for holding, the other end is straight clamping rod, the hinge of the two tongs will wear and tear in the long-term use process, cause the hinge to loosen, when the clamping rod is long, the distal end of the two clamping rods will slide (not relative operation) when clamping object, because the included angle is not limited, the stability of clamping is poor, especially the tongs which has been used to a certain extent, the clamping object is often unstable during use, causing the tongs to be too low in use efficiency. SUMMARY
[0003] The utility model discloses a structure is reasonable, improves use efficiency, and the effect of preventing sidesliding is good, and the device can directly adjust the included angle of tongs.
[0004] In order to realize the above-mentioned purpose, the utility model provides a technical scheme, which is a tongs included angle adjusting device, which comprises a positioning plate provided on a tong body, an included angle adjusting hole provided on the positioning plate, a movable limiting bolt installed on the included angle adjusting hole, and the limiting bolt is located outside the other tong body of the tongs.
[0005] Scheme 1: a limiting plate is installed on one tong body of the tongs, an included angle adjusting hole is provided on the limiting plate, and the positioning plate is connected with the limiting bolt after passing through the positioning plate slot hole on the other tong body (see Figure 2 )。
[0006] Scheme 2: the top of the positioning plate is bent horizontally and then bent downward to form an "n" type tong limiting piece, and the other tong body of the tongs is located in the tong limiting piece (see Figure 5 )。
[0007] The cross section of the tong body and the tong limiting piece can have various shapes, and one side or both sides are provided with a positioning plate, and the positioning plate is provided with an adjusting hole.
[0008] The limiting tool is made of a bolt or a spring latch.
[0009] The number of included angle adjusting holes is greater than 2, and the included angle adjusting holes are uniformly distributed along the length direction of the positioning plate, and the included angle adjusting holes are internal thread holes or through holes.
[0010] If the positioning plate is in the shape of "n", the other jaw body of the clamp is located between the two walls of the positioning plate (see Figure 5 ).
[0011] After the above scheme is adopted, the positioning plate on the jaw body passes through the positioning plate slot to form an adjusting end (see Figure 2 ), the limiting bolt is inserted into the included angle adjusting hole of the adjusting end to adjust the opening and closing degree of the two jaw bodies of the clamp, and after a plurality of included angle adjusting holes are adopted, the requirement of different opening and closing degrees of the clamp can be realized. The jaw body in the shape of "n" and the limiting piece can also be directly inserted and locked (see Figure 5 ), the included angle locking is convenient and not easy to deviate.
