[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 As shown, this utility model is a gas extraction sealing pipe screwing device, including a first clamping arm 1 and a second clamping arm 5, and further including: an arc-shaped first open clamping groove 2 provided on the inner side of the first clamping arm 1, and an arc-shaped second open clamping groove 6 provided on the inner side of the second clamping arm 5. The first clamping arm 1 and the second clamping arm 5 have the same structural shape. The first clamping arm 1, the second clamping arm 5, the first open clamping groove 2, and the second open clamping groove 6 are made of stainless steel square steel. A first connecting lug 9 is provided at one end of the first clamping arm 1, and a second connecting lug 10 is provided at one end of the second clamping arm 5. A stainless steel pin 4 passes through the first connecting lug 9 and the second connecting lug 10, and the stainless steel pin 4 connects the first connecting lug 9 and the second connecting lug 10 in series, and leads to the connection point. Injecting grease allows the first clamping arm 1 and the second clamping arm 5 to rotate around the stainless steel pin 4. Tightening teeth 8 are provided on the inner sides of the first open clamping groove 2 and the second open clamping groove 6. The cross-section of the tightening teeth 8 is trapezoidal, and the teeth 8 are arranged at equal intervals on the inner sides of the first open clamping groove 2 and the second open clamping groove 6. After the two PVC pipes are screwed together, the first clamping arm 1 and the second clamping arm 5 are fitted over the PVC pipes, and the first open clamping groove 2 and the second open clamping groove 6 are clamped over the PVC pipes. Then, the worker holds the clamping arms and tightens the PVC pipes, thereby reducing the time spent installing the gas extraction sealing pipe and increasing its sealing performance to prevent gas extraction efficiency from being reduced due to pipeline leakage.

[0024] When performing the PVC sealing pipe connection operation, after the two PVC pipes are screwed together, the first clamping arm 1 and the second clamping arm 5 are put on the outside of the PVC pipe, and the first open clamping groove 2 and the second open clamping groove 6 are clamped on the outside of the PVC pipe. Then the worker holds the clamping arm and screws the PVC pipe tight.

[0025] As a further implementation of this embodiment, such as Figure 1-4As shown, anti-slip protection components are provided on one side of the first clamping arm 1 and the second clamping arm 5 and on the outside of the screwing tooth block 8. The anti-slip protection components include a rubber sleeve 3, which is nested on the outside of the screwing tooth block 8. The cross-section of the rubber sleeve 3 is trapezoidal, and the inside of the rubber sleeve 3 fits with the screwing tooth block 8. When tightening the PVC sealing pipe, the rubber sleeve 3 is used to pad between the screwing tooth block 8 and the outside of the PVC pipe to increase the friction between the contact surfaces and prevent slippage. At the same time, it prevents excessive clamping and damage to the PVC pipe. An anti-slip rubber sleeve 7 is provided on one side of the first clamping arm 1 and the second clamping arm 5, and the anti-slip rubber sleeve 7 is used to prevent the worker's hand from slipping when holding the device with force.

[0026] Working principle: When using the screwing device, firstly, the anti-slip rubber sleeve 7 is fitted onto the outer handles of the first clamping arm 1 and the second clamping arm 5, and the rubber clamp 3 is fitted onto the outside of the screwing tooth block 8. The first connecting ear 9 and the second connecting ear 10 are connected in series using the stainless steel pin 4. At the same time, grease is injected into the connection, so that the first clamping arm 1 and the second clamping arm 5 can rotate with the stainless steel pin 4 as the center. After screwing the two PVC pipes through the threaded connection, the first clamping arm 1 and the second clamping arm 5 are fitted onto the outside of the PVC pipes. At the same time, the first open clamping groove 2 and the second open clamping groove 6 are clamped onto the outside of the PVC pipes. Then, the worker holds the clamping arm to screw the PVC pipes tightly. The anti-slip rubber sleeve 7 can prevent the worker from slipping when holding the device with force. The rubber clamp 3 is used to increase the friction between the contact surface of the screwing tooth block 8 and the outside of the PVC pipe, preventing slippage and preventing excessive clamping that could damage the PVC pipe. This allows for a quick and stable screwing and tightening of the gas extraction PVC sealing pipe.
