Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, specifically a pair of vise pliers with a handheld anti-slip structure. Background Technology

[0002] A bolt cutter is a tool whose jaws can lock shut and generate a large clamping force. It is mainly used to clamp parts for riveting, welding, grinding, and other machining processes. Its key feature is that the jaws can lock quickly and generate a large clamping force, preventing the clamped parts from loosening and deforming. In addition, the bolt cutter has a screw-adjustable knob on the jaws, which can be adjusted to the most suitable position for clamping parts of different thicknesses.

[0003] Chinese utility model patent CN202412073U discloses a pair of clamps, relating to the field of oxygen purification technology. The clamps include a fixed jaw, a movable jaw, a fixed handle, a movable handle, an opening handle, a support plate, an adjusting screw, a tension spring, and rivets. The movable jaw is connected to the front of the fixed handle via rivets. An adjusting screw is located at the rear of the fixed handle. A tension spring is located between the middle of the fixed handle and the movable jaw. The front of the movable handle is fixedly connected to the movable jaw via rivets. The front of the support plate is connected to the movable handle via rivets. The opening handle is connected to the rear of the movable handle via rivets. The front of the opening handle has a flat plate that connects to a protrusion in the middle of the support plate. The movable handle, the opening handle, and the support plate form a locking structure. This utility model has a reasonable design, simple structure, is easy to manufacture, low in cost, and convenient to use. Workpieces can be quickly clamped and released by opening and gripping the opening handle.

[0004] Because existing pliers have problems such as being inconvenient to adjust the size of the jaw opening when clamping objects of different sizes, and being unable to prevent accidental activation of the adjustment mechanism after adjusting the jaw size, and the lack of a gripping anti-slip structure when holding the pliers by hand, we propose a pliers with a gripping anti-slip structure to solve the above-mentioned problems.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-6 Existing bolt cutters are not convenient for adjusting the size of the opening of the clamp head when clamping objects of different sizes. In order to solve this technical problem, this embodiment discloses the following technical content.

[0029] A fixed jaw 2 is rotatably connected to the upper left inner end of the pliers handle 1, and the right end of the fixed jaw 2 is rotatably connected to the left inner end of the pliers handle 1 by a rivet 6. A jaw 3 is fixedly connected to the lower left end of the fixed jaw 2. A movable handle 4 is connected to the lower part of the pliers handle 1, and a movable jaw 5 is rotatably connected to the left inner end of the movable handle 4. A jaw 3 is fixedly connected to the upper left end of the movable jaw 5. The upper and lower right ends of the movable jaw 5 are rotatably connected to the left ends of the pliers handle 1 and the movable handle 4 by rivets 6, respectively. Rivets 6 are also connected through the upper and lower right ends of the movable jaw 5. A connecting block 7 is fixedly connected to the middle right side of the movable jaw 5. A fixing strip 8 is fixedly connected to the right end of the upper inner surface of the pliers handle 1. The internal connection is a spring 9, and the left end of the spring 9 is fixedly connected to a rotating rod 10. The rotating rod 10 is rotatably connected to the middle right side of the connecting block 7. The right side of the spring 9 is fixedly connected to a connecting ring 11, and the connecting ring 11 is slidably connected to the outside of the fixing strip 8. The right side of the clamp handle 1 is fixedly connected to a fixing handle 12, and the left side of the fixing handle 12 is provided with a storage slot 13. The inner side of the storage slot 13 is connected to a support plate 14. The left end of the support plate 14 is rotatably connected to the inner left end of the movable handle 4 by a rivet 6. The right side of the support plate 14 is fixedly connected to a locking block 15. The middle right side of the fixing handle 12 is connected to a fixing device 16. The inner right end of the movable handle 4 is rotatably connected to an opening handle 19 by a rivet 6.

[0030] The pliers handle 1, fixed pliers head 2, movable handle 4, movable pliers head 5, support plate 14, and opening handle 19 are connected to each other by rivets 6, so that the pliers handle 1, fixed pliers head 2, movable handle 4, movable pliers head 5, support plate 14, and opening handle 19 can be linked together. When it is necessary to adjust the size of the jaws 3 between the fixed pliers head 2 and the movable pliers head 5, turn the adjusting screw 1601. The adjusting screw 1601 is threaded into the fixed handle 12. The left side of the adjusting screw 1601 contacts the locking block 15. Adjust the length of the left end of the adjusting screw 1601 inside the storage slot 13 so that the left end of the adjusting screw 1601 limits the position of the right end of the support plate 14 inside the storage slot 13, so that the angle of the support plate 14 changes, thereby adjusting the size of the jaws 3 between the fixed pliers head 2 and the movable pliers head 5.

[0031] Example 2: Existing bolt cutters, after adjusting the jaw size, do not easily prevent accidental activation of the adjustment mechanism. Therefore, this example uses the following technical solution, such as... Figures 1-5 As shown;

[0032] The fixing device 16 is composed of an adjusting screw 1601, a threaded groove 1602, an annular groove 1603 and a fixing bolt 1604. The adjusting screw 1601 has a threaded groove 1602 on its outer side and an annular groove 1603 on its right outer end. The fixing bolt 1604 is slidably connected inside the annular groove 1603. The upper and lower ends of the right side of the fixing handle 12 are both provided with threaded grooves 1602, and the inner side of the threaded groove 1602 is threadedly connected to the left end of the fixing bolt 1604.

[0033] After adjusting the size between the jaws 3, align the left end of the stabilizing bolt 1604 with the threaded groove 1602 and tighten the stabilizing bolt 1604 so that the stabilizing bolt 1604 fixes the adjusting screw 1601 on the fixed handle 12, preventing accidental rotation of the adjusting screw 1601 during use, which would cause the size between the jaws 3 to change and thus affect the use.

[0034] Example 3: Existing bolt cutters lack a non-slip grip when held by the handle. Therefore, this example addresses this issue through the following technical solution: Figures 1-5 As shown;

[0035] A first anti-slip pad 17 is fixedly connected to the outer side of the fixed handle 12, and a second anti-slip pad 18 is fixedly connected to the outer side of the right end of the movable handle 4.

[0036] The first anti-slip pad 17 and the second anti-slip pad 18 on the outer side of the fixed handle 12 and the movable handle 4 fit against the user's palm, which enables the pliers to have an anti-slip function.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
