Technical Field

[0001] The utility model relates to the field of wrenches, in particular to a high-strength tap wrench. Background Art

[0002] A high-strength tap wrench is a tool specially used for cutting threads of high-hardness metal materials. High-strength tap wrenches are usually used to cut stainless steel, alloy steel, titanium alloy and other metal materials with higher hardness. These materials are usually more difficult to cut than ordinary carbon steel. Using a high-strength tap wrench can ensure the accuracy and quality of thread cutting.

[0003] The existing high-strength tap wrench places metal materials on the outer block of the wrench, connects the inner block with an adjusting bolt, and drives the inner block to move up and down by twisting the bolt to adjust the square hole to adapt to metal materials of different sizes. The metal material can only be installed and removed by continuously twisting the bolt, which is troublesome to operate. Twisting the bolt is time-consuming and laborious, resulting in low tapping efficiency.

[0004] Therefore, it is necessary to design a high-strength tap wrench that can quickly disassemble and install metal materials, is easy to operate, saves time and labor, and improves tapping efficiency. Utility Model Content

[0007] Furthermore, the support block is made of alloy steel, which has higher strength, hardness and wear resistance.

[0008] Furthermore, the handles are provided with anti-slip grooves to increase the contact surface and prevent slipping.

[0010] Furthermore, a handle is connected to the left portion of the rotating frame, which is convenient for holding and rotating the rotating frame.

[0011] Furthermore, it also includes a tightening mechanism, which includes a supporting ring, a rotating ring, a first torsion spring, a rotating rod, a second torsion spring and a connecting ring. The supporting block is connected to the supporting ring, and the supporting ring is connected to the rotating ring through the first torsion spring. The upper right side of the rotating ring is rotatably connected to the rotating rod, and the second torsion spring is connected between the rotating rod and the rotating ring. The upper part of the adjusting screw is connected to the connecting ring, and the connecting ring is in contact with the rotating rod. By rotating the rotating rod to the right to disengage from the connecting ring, the second torsion spring rotates and deforms, and then the hand is released, the second torsion spring rotates and resets, the rotating rod rotates and resets and contacts the connecting ring, and the rotating ring is reset by the rotation of the first torsion spring, and then the adjusting screw is tightened.

[0012] The beneficial effects of the utility model are as follows: 1.

[0013] 2. The utility model moves the adjusting screw downward by twisting it in the reverse direction, thereby driving the sliding block to move downward to clamp and fix the metal material, and then tapping is performed. The utility model can be used for tapping with various taps, and is strong, durable and low in cost.

[0014] 3. The utility model turns the adjusting screw, tightens the adjusting screw and then releases it, the second torsion spring rotates and resets, the rotating rod rotates and resets to contact the connecting ring, and then the first torsion spring rotates and deforms and then rotates and resets to drive the rotating ring to reset, thereby automatically tightening the adjusting screw, preventing the adjusting screw from rotating loose to produce a gap and causing unstable fixation, avoiding deformation and damage of the adjusting screw, extending the service life and reducing maintenance costs.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0022] High strength tap wrench, such as Figure 1-Figure 4 As shown, it includes a support block 1, a handle 2, a sliding block 3, an adjusting screw 4 and a quick-release mechanism 5. The support block 1 is made of alloy steel. The left and right sides of the support block 1 are connected with handles 2, and the handles 2 are provided with anti-slip grooves. The sliding block 3 is slidably connected inside the support block 1, and the adjusting screw 4 is rotatably connected to the sliding block 3. The adjusting screw 4 is connected to the support block 1 through a thread. The lower part of the support block 1 is provided with a quick-release mechanism 5 for quickly removing the wrench.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the quick release mechanism 5 includes a support frame 51, a rotating frame 52, a sliding frame 53 and a spring 54. The support frame 51 is connected to the lower part of the support block 1, the rotating frame 52 is rotatably connected to the support frame 51, the left part of the rotating frame 52 is connected to a handle, the sliding frame 53 is slidably connected to the inner side of the lower part of the support block 1, the sliding frame 53 is in contact with the rotating frame 52, and a spring 54 is connected between the sliding frame 53 and the support block 1.

[0024] When it is necessary to tap metal materials, the device can be used. The device is picked up by the handle 2. The handle 2 is provided with anti-slip grooves to increase the contact surface and prevent slipping. The adjusting screw 4 is twisted to move upward, thereby driving the sliding block 3 to move upward. Then, the rotating frame 52 is rotated downward by 90 degrees through the grip to move the sliding frame 53 upward. The spring 54 is stretched, and the metal material is placed on the supporting block 1. The supporting block 1 is made of alloy steel and has higher strength, hardness and wear resistance. Then, the adjusting screw 4 is twisted in the opposite direction to move downward, thereby driving the sliding block 3 to move downward to clamp and fix the metal material, and then tapping is performed. It can be used for tapping various taps, and is strong, durable, and has a low cost. When the tapping is completed and the metal material needs to be replaced, the rotating frame 52 is rotated upward by ninety degrees, the spring 54 rebounds, the sliding frame 53 moves downward and resets, and then the metal material is removed and the untapped metal material is put in, and then the rotating frame 52 is rotated downward by ninety degrees again, so that the sliding frame 53 moves upward, the spring 54 is stretched, and the metal material is clamped and fixed, and then tapping is performed, thereby realizing rapid disassembly and installation of the metal material, simple operation, saving time and labor, and improving the efficiency of tapping. After the tapping is completed, the sliding block 3 is moved upward by twisting the adjusting screw 4, and then the metal material is removed, and then the rotating frame 52 is rotated upward to reset, the spring 54 rebounds, and the sliding frame 53 is reset.

[0025] like Figure 1 and Figure 5 As shown, it also includes a tightening mechanism 6, which includes a support ring 61, a rotating ring 62, a first torsion spring 63, a rotating rod 64, a second torsion spring 65 and a connecting ring 66. The support block 1 is connected to the support ring 61, and the support ring 61 is connected to the rotating ring 62 through the first torsion spring 63. The upper right side of the rotating ring 62 is rotatably connected to the rotating rod 64, and a second torsion spring 65 is connected between the rotating rod 64 and the rotating ring 62. The upper part of the adjusting screw 4 is connected to the connecting ring 66, and the connecting ring 66 is in contact with the rotating rod 64.

[0026] When it is necessary to turn the adjusting screw 4, the rotating rod 64 can be disengaged from the connecting ring 66 by turning the rotating rod 64 to the right, the second torsion spring 65 rotates and deforms, and then the adjusting screw 4 is turned. After tightening the adjusting screw 4, let go, the second torsion spring 65 rotates and resets, and the rotating rod 64 rotates and resets to contact the connecting ring 66. When the adjusting screw 4 loosens and rotates during use, the first torsion spring 63 rotates and deforms and then rotates and resets, thereby driving the rotating ring 62 to reset, thereby automatically tightening the adjusting screw 4, preventing the adjusting screw 4 from rotating loose and causing a gap to cause unstable fixation, avoiding deformation and damage of the adjusting screw 4, extending the service life, and reducing maintenance costs.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
