This solves the problems mentioned in the background art, such as insufficient clamping force on the gate during use, leading to loosening and slippage, poor safety, and the loss of a large portion of the user's strength due to the inconvenience of using the equipment.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a wrench for opening an oil well gate, comprising a main body, a through hole at the top of the main body, a linkage shaft inserted into the through hole, a limit switch rotatably connected to the surface of the linkage shaft, rectangular grooves on both sides of the limit switch, an adjusting nut engaged inside the rectangular groove, an adjusting rod threadedly connected inside the adjusting nut, a circular hole on one side of the main body, a circular rod fixedly connected inside the circular hole, an angle adjuster rotatably connected to the surface of the circular rod, and a spring fixedly connected inside the main body.

[0014] Optionally, a handle is fixedly connected to the top of the angle adjuster, and an anti-slip pad is fixedly connected to the surface of the handle.

[0015] (III) Beneficial Effects

[0016] This utility model provides a wrench for opening an oilfield gate, which has the following advantages:

[0017] 1. This oilfield gate opening wrench, through the setting of limiters, adjusting nuts, adjusting rods, and clamps, allows for better gate opening when the equipment needs to be used. Align the equipment with the gate, rotate the adjusting nut to displace the adjusting rod, and push it out. After adjusting to a suitable distance according to the actual situation, clamp the clamp onto the gate. This ensures better gate fixation and effectively prevents insufficient clamping force during use, which could lead to loosening and slippage, resulting in poor safety.

[0018] 2. This oil well gate opening wrench, through the setting of an angle adjuster, spring, push block, and limit hole, allows the angle adjuster to rotate freely when the operator presses the push block to push back the limit pin when opening the gate. By rotating the handle, the angle can be adjusted according to the actual situation. After adjusting to the most labor-saving angle, the spring's reaction force pushes out the limit pin to lock the push block, thus fixing the angle adjuster. This makes it easier and less strenuous to adjust the angle when using the equipment, effectively preventing the loss of a large amount of strength due to the inconvenience of the equipment during use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a wrench for opening an oil well gate, comprising a main body 1. A through hole is formed at the top of the main body 1, and a linkage shaft 2 is inserted into the through hole. A limiter 3 is rotatably connected to the surface of the linkage shaft 2. Rectangular grooves are formed on both sides of the limiter 3, and adjusting nuts 4 are engaged inside the rectangular grooves. An adjusting rod 5 is threadedly connected inside the adjusting nut 4. Through the arrangement of the limiter 3, adjusting nut 4, adjusting rod 5, and clamp 9, when the equipment needs to open the gate, the equipment is aligned with the gate, the adjusting nut 4 is rotated to displace the adjusting rod 5, and the adjusting rod 5 is pushed out. After adjusting to a suitable distance according to the actual situation, the clamp 9 is engaged with the gate, thereby allowing the equipment to better fix the gate, effectively preventing insufficient clamping force on the gate during use, which could lead to loosening and slippage. The main body 1 has a circular hole on one side, and a circular rod 6 is fixedly connected inside the circular hole. An angle adjuster 7 is rotatably connected to the surface of the circular rod 6. A spring 8 is fixedly connected inside the main body 1. With the setting of angle adjuster 7, spring 8, push block 12 and limit circular hole, when the operator opens the gate, he presses the push block 12 to push back the limit pin 11, so that the angle adjuster 7 can rotate freely. By rotating the handle 13, the angle can be adjusted according to the actual situation. After adjusting to the most labor-saving angle, the reaction force of the spring 8 pushes out the limit pin 11 to lock the push block 12 and fix the angle adjuster 7. This makes it easier to adjust the angle with less effort when using the equipment, thus effectively avoiding the loss of a lot of strength due to the inconvenience of the equipment when the user is using it.

[0026] A clamp 9 is fixedly connected to one side of the adjusting rod 5. The surface of the clamp 9 is provided with threads, according to... Figure 1 As shown, the screw threads serve to tighten the gate.

[0027] A limiting hole is provided at the bottom of the main body 1. A limiting plate 10 is fixedly connected inside the limiting hole, and a limiter 3 is snapped into the inner side of the limiting plate 10. Figure 3 As shown, the limit plate 10 serves to adjust the limit of the limiter 3.

[0028] The internal transmission connection of spring 8 is limited by a limit pin 11, and a push block 12 is engaged with the surface of the limit pin 11. Figure 4 As shown, by setting up the push block 12, the limit pin 11 is pushed.

[0029] The angle adjuster 7 has multiple limiting holes on one side, and a push block 12 is connected inside the limiting holes for transmission. Figure 3 As shown, the limiting hole serves to limit the movement of the push block 12.

[0030] A handle 13 is fixedly connected to the top of the angle adjuster 7, and an anti-slip pad is fixedly connected to the surface of the handle 13. Figure 2 As shown, the anti-slip pad serves to prevent the handle 13 from slipping and falling off.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When it is necessary to use the equipment to open the gate, align the equipment with the gate, turn the adjusting nut 4 to move the adjusting rod 5, push the adjusting rod 5 out, and adjust it to a suitable distance according to the actual situation. Then, clamp the clamp 9 onto the gate so that the equipment can better fix the gate.

[0033] Second step: When the staff opens the gate, press the push block 12 to push the limit pin 11 back, so that the angle adjuster 7 can rotate freely. Turn the handle 13 to adjust the angle according to the actual situation. After adjusting to the angle that requires the least effort, use the reaction force of the spring 8 to push the limit pin 11 out and lock the push block 12 to fix the angle adjuster 7 before opening the gate.

[0034] Third step: Finally, press down the push block 12 to push back the limit pin 11, so that the angle adjuster 7 can rotate freely. Rotate the handle 13 to adjust the angle according to the actual situation. After adjusting to the angle that requires the least effort, use the reaction force of the spring 8 to push out the limit pin 11 and lock the push block 12 to fix the angle adjuster 7. Rotate the adjusting nut 4 to move the adjusting rod 5. Push the adjusting rod 5 back and retract the equipment.
