This problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a positioning component 3 and a storage component 4 are added to the application document.

[0030] More specifically:

[0031] like Figure 1-Figure 4 As shown:

[0032] In combination with the above content, the positioning component 3 is hinged to three groups of legs 32 in a circular array on the outer wall of the storage tube 1, and an insertion rod 34 is arranged inside the leg 32.

[0033] In the present embodiment: when the gas pipeline venting device is in use, the legs 32 are pulled to drive the legs 32 to unfold, and at the same time, the support rod 35 will pull the slider 33 to slide inside the legs 32, and then the slider 33 can be used to push the insertion rod 34 to slide out from the inside of the legs 32, and the unfolding angle of each group of legs 32 is adjusted according to the positioning environment. After the adjustment is appropriate, the position of the slider 33 can be limited by rotating the screw 37 to drive the abutment plate 38 to press against the slider 33, and then the insertion rod 34 is inserted into the ground, and the storage tube 1 is supported by the legs 32 to locate the position of the storage tube 1, and then the air inlet connector 5 can be connected to the gas pipeline to vent the gas pipeline.

[0034] Going further:

[0035] like Figure 1-Figure 4 As shown:

[0036] In order to facilitate the folding and storage of the legs 32 and the rods 34, in an optional embodiment: a rubber anti-skid pad is symmetrically fixedly connected to the side of the surface of the abutment plate 38 away from the slider 33; a scraper 36 with a frame-type structure is fixedly connected to the bottom end of the legs 32; and a top cover 31 is connected to the top end of the surface of the flare tube 2 via a fixing belt.

When the flare tube 2 is not in use, the top cover 31 can be used to seal the top of the flare tube 2 to prevent foreign matter and impurities from entering the interior of the flare tube 2 and affecting the normal use of the flare tube 2.

[0038] More specifically:

[0039] like Figure 1-Figure 4 As shown:

[0040] In combination with the above content, a storage assembly 4 is provided on the surface of the flare tube 2, and the storage assembly 4 includes a fixing ring 2 43 fixedly connected to the top of the flare tube 2, a fixing ring 1 42 is fixedly connected to the surface of the storage tube 1, a limiting rod 45 is fixedly connected to the bottom surface of the fixing ring 2 43, and the limiting rod 45 is slidably connected to the inside of the fixing ring 1 42, a locking bolt 44 is screwed on one side of the surface of the fixing ring 1 42 close to the limiting rod 45, and a sealing ring gasket 46 is fixedly connected to the bottom end of the outer wall of the flare tube 2; a sliding rod 41 is symmetrically fixedly connected to the bottom surface of the fixing ring 2 43, and the bottom end of the sliding rod 41 passes through the surface of the fixing ring 1 42 and is fixedly connected to a limiting block arranged below the fixing ring 1 42.

[0041] In the present embodiment: when the device is not in use, the flare barrel 2 is stored in the interior of the storage tube 1 to reduce the area occupied by the device, which is convenient for storage and transportation of the device. When the device is in use, the flare barrel 2 is driven to slide from the interior of the storage tube 1 by pulling the fixing ring 2 43, which is convenient for igniting and venting the gas through the flare barrel 2. At the same time, the locking bolt 44 is rotated to drive the limiting rod 45 to be pressed tightly, so that the height of the flare barrel 2 can be locked, which is convenient for adjusting the height of the flare barrel 2 according to usage requirements, thereby improving the flexibility of the device. When the flare barrel 2 moves, the sliding rod 41 will drive the fixing ring 2 43 to slide inside, increase the stability of the movement of the flare barrel 2, and improve the sealing effect between the storage tube 1 and the flare barrel 2 through the sealing ring gasket 46 to prevent the gas from leaking through the storage tube 1 and the flare barrel 2.

[0042] Working principle: When the gas pipeline venting device is in use, the legs 32 are pulled to spread out, and at the same time, the support rod 35 pulls the slider 33 to slide inside the legs 32, and then the slider 33 can push the insertion rod 34 to slide out from the inside of the legs 32. The spread angle of each set of legs 32 is adjusted according to the positioning environment. After the adjustment is appropriate, the position of the slider 33 can be limited by rotating the screw 37 to drive the abutment plate 38 to press against the slider 33, and then the insertion rod 34 is inserted into the ground, and the storage tube 1 is supported by the legs 32 to control the position of the storage tube 1. The position is positioned, and then the air inlet joint 5 can be connected to the gas pipeline to vent the gas pipeline. Then, the flare barrel 2 is driven to slide from the inside of the storage tube 1 by pulling the fixing ring 2 43, so that the gas is ignited and vented through the flare barrel 2. At the same time, the locking bolt 44 is turned to drive and tighten with the limit rod 45, so that the height of the flare barrel 2 can be locked, so that the height of the flare barrel 2 can be adjusted according to the use requirements, thereby improving the flexibility of the device. When the flare barrel 2 moves, the sliding rod 41 will drive the fixing ring 2 43 to slide inside, increasing the movement of the flare barrel 2 The stability of the device is improved by using the sealing ring gasket 46 to improve the sealing effect between the storage tube 1 and the flare tube 2 to prevent the gas from leaking between the storage tube 1 and the flare tube 2. When storing the device, the reverse screw 37 is used to drive the plate 38 to be stored inside the slider 33, and the leg 32 can be flipped to fold the leg 32 and the storage tube 1 for storage, and the screw 37 is turned to drive the plate 38 to lock the position of the slider 33. At the same time, the rubber anti-skid pad on the surface of the plate 38 can increase the friction between the leg 32 and the plate 38, thereby improving the stability of the contact between the plate 38 and the leg 32. During this period, the support rod 35 will push the slider 33 to move upward, so that the slider 33 pulls the plug rod 34 to be stored inside the support leg 32, avoiding the bottom end of the plug rod 34 being exposed to the outside and scratching others. At the same time, the scraper 36 can scrape off the dirt on the surface of the plug rod 34. When the torch tube 2 is not in use, the top cover 31 can be used to cover the top of the torch tube 2 to avoid foreign matter and impurities from entering the interior of the torch tube 2 and affecting the normal use of the torch tube 2. By storing the torch tube 2 inside the storage tube 1, the area occupied by the device is reduced, which facilitates the storage and transportation of the device.
