Description

Technical Field

[0001] This utility model relates to the field of manual tool manufacturing technology, and more specifically, to a multifunctional opener. Background Technology

[0002] Hand tools include bottle openers, screwdrivers, oyster openers, nutcrackers, crab crackers, watermelon cutters, durian openers, fruit cutters, and pomelo openers. These hand tools have the functions of cutting, slicing, prying, clamping, pliers, and supporting. However, most of these hand tools are currently individual pieces, and users need to purchase them one by one to use them. Purchasing all of these hand tools at once results in wasted resources and places a great economic burden on users. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a multifunctional mouth opener, specifically achieved through the following technical solution:

[0004] A multifunctional mouth opener includes a first handle and a second handle made of 304 stainless steel, stamped into a U-shaped groove by a punch press. The first and second handles are bent on their inner sides with upper and lower lugs, respectively. The upper and lower lugs are provided with upper and lower hinge holes. The first and second handles are movably connected by a hinge shaft passing through the upper hinge hole, a torsion spring, and the lower hinge hole. The inner sides of the first and second handles on the right side of the hinge shaft are provided with upper and lower serrations. The first and second handles on the left side of the hinge shaft are riveted with a main sharp blade and a secondary sharp blade. The upper and lower sides of the non-connecting ends of the main sharp blade and the secondary sharp blade are provided with cutting edges. The sharpness angle of the cutting edges is 20° to 60°, and the closing gap of the cutting edges is ≤0.1mm.

[0005] Furthermore, both the first and second handles are provided with an arc shape, which is ergonomically designed to fit the hand's grip curve in order to distribute the applied pressure. The surfaces of the first and second handles are polished to improve rust resistance and grip feel.

[0006] The beneficial effect of adopting the above-mentioned further solution is that by setting arcs on the first and second handles, and the arcs being ergonomically designed, the grip is more comfortable and stable during use.

[0007] Furthermore, the first handle has a bottle opener at its end, and the second handle has a circular hanging hole at its end. The diameter of the circular hanging hole is φ5~8mm, which can support storage methods such as hooks and tool ropes to prevent tools from falling out.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by providing a bottle opener at the end of the first handle, the manual tool becomes multifunctional, and by providing a circular hanging hole at the end of the second handle, storage is simple and convenient.

[0009] Furthermore, the torsion spring has 2 to 6 turns, one end of the torsion spring is supported on the inner wall of the U-shaped groove of the first handle, and the other end of the torsion spring is supported on the inner wall of the U-shaped groove of the second handle. The first handle and the second handle are rotatably connected by a hinge shaft passing through the upper hinge hole, the torsion spring, and the lower hinge hole.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, by providing torsion springs in the grooves of the first handle and the second handle, the main sharp blade and the secondary sharp blade remain in a closed state under the action of the torsion springs supporting the first handle and the second handle.

[0011] Furthermore, the hinge shaft is made of 45# steel and has been quenched to a surface hardness of HRC45-50. A 0.8-1.5mm nylon washer is nested between the upper and lower hinge holes of the hinge shaft to reduce direct friction between metals and extend rotational life.

[0012] The beneficial effects of adopting the above-mentioned further solution are that by using 45# steel to quench the hinge shaft to achieve a surface hardness of HRC45~50, the hinge shaft can be kept from long-term torsion without wear. In addition, a nylon washer is nested between the upper and lower hinge holes of the hinge shaft, which effectively reduces direct friction between metals and extends the rotational life.

[0013] Furthermore, the module spacing between the upper and lower saw teeth is 1–4.5 mm, the tooth profile angle is 60°, the number of saw teeth is 5–15, and the meshing depth is ≥1–5 mm to ensure deformation stability.

[0014] The beneficial effects of adopting the above-mentioned further solution are that by using a sawtooth module spacing of 1 to 4.5 mm, the meshing stability is achieved; by using 5 to 15 sawtooths, various customer needs can be met; and by using a sawtooth meshing depth of ≥1 to 5 mm, the clamped object is not easily dislodged.

[0015] Furthermore, the beveled edge angle of the main sharp blade and the secondary sharp blade is 15° to 45°, the thickness is ≤0.01mm to 3.5mm, the beveled edge is subjected to high-frequency quenching to make its hardness HRC55 to 60, and laser cutting plus quenching and sharpening process is used to ensure the cutting sharpness.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it effectively ensures the sharpness and hardness of the main and secondary sharp blades.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a multi-functional mouth opener through the above design. This multi-functional mouth opener is provided with a main sharp blade, a secondary sharp blade, upper serrations, lower serrations, a bottle opener, and a circular hanging hole on the first and second handles. It realizes the functions of opening bottle caps, screw openers, oyster openers, walnut crackers, crab crackers, watermelon cutters, durian openers, fruit cutters, and grapefruit openers, thereby solving the problems of the prior art, saving space and resources, and achieving the integrated effect of using a multi-functional manual tool.
