[0002] Smoke and dust refers to particulate matter floating in the air formed during processes such as fuel combustion, high-temperature melting, and chemical reactions. Typical smoke and dust is the black smoke emitted from a chimney, which is small black carbon particles of incomplete combustion. The particle size of smoke and dust is very small, generally less than 1 gm. A smoke and dust tester is used to detect the amount of smoke and dust per cubic meter of air in a fixed volume of the atmosphere.

[0003] After retrieval, a sampling gun for a smoke and dust tester disclosed in a Chinese patent with the publication number CN221148217U improves the clamping stability of the sampling gun at the sampling port of the chimney; the utility model is convenient to adjust and use and has a broad market prospect. However, this device does not have a quickly detachable tripod. When placing this device on the ground, the absence of a tripod is likely to cause the sampling gun to tip over and bump, resulting in damage to the sampling gun or adhesion of impurities on the ground, affecting the test.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

A tripod is slidably connected to the inner wall of each T-shaped groove. A slot is formed on the upper surface of each tripod. Three connecting frames are fixedly connected to the upper surface of the support disk. A plug rod is slidably connected to the inner wall of each connecting frame. The outer surface of each plug rod is inserted into the corresponding slot. The outer surface of each plug rod is slidably connected to the support disk. A first spring is sleeved on the outer surface of each plug rod. The top end of each first spring is fixedly connected to the corresponding connecting frame, and the other end is fixedly connected to the corresponding plug rod.

[0007] Further, a support frame is arranged above the support disk. A screw rod is threadedly connected to the inner wall of the support frame. The outer surface of the screw rod is rotatably connected to the support disk. The bottom end of the screw rod is fixedly connected to a runner.

[0008] Further, two telescopic rods are fixedly connected to the upper surface of the support disk. Two connecting blocks are fixedly connected to the outer surface of the support frame. The outer surface of each telescopic rod is rotatably connected to the corresponding connecting block.

[0009] Further, a fixing frame is fixedly connected to the upper surface of the support frame, and a support plate is slidably connected to the inner wall of the fixing frame.

[0010] Further, two connecting columns are fixedly connected to the upper surface of the support plate. A second spring is fixedly connected to the inner bottom wall of each connecting column. The top end of each second spring is fixedly connected to a connecting rod, and the outer surface of each connecting rod is slidably connected to the corresponding connecting column.

[0011] Further, a fixing ring is fixedly connected to the top end of each connecting rod. A first pulley is rotatably connected to the inner wall of each fixing ring. A second pulley is provided above each first pulley.

[0012] Further, a sliding rod is slidably connected to the inner wall of each fixing ring. A U-shaped plate is fixedly connected to the bottom end of each sliding rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting components such as a support disc, a T-shaped groove, a slot, a footrest, a plug rod, a connecting frame, and a first spring, the present utility model pulls the plug rod to move vertically upward along the corresponding connecting frame. At this time, the first spring starts to be compressed, and then inserts the footrest along the corresponding T-shaped groove until the slot and the corresponding plug rod are on the same central axis. At this time, release the plug rod, and the first spring will push the corresponding plug rod into the corresponding slot under the action of its resilience force, thereby achieving the effect that the device can support the sampling gun by setting a quickly detachable and installable footrest.

[0015] 2. By setting components such as a telescopic rod, a support frame, a screw rod, and a runner, the present utility model rotates the runner, and the runner will drive the screw rod to rotate. The rotation of the screw rod will drive the support frame to move vertically along the screw rod. At this time, the support frame will drive the telescopic rod to stretch or contract. Through the connection of the telescopic rod, the support frame will not be deflected when the screw rod is rotated, thereby achieving the effect that the height of the support frame can be quickly adjusted by rotating the screw rod.

[0024] In this embodiment, the outer surface of each insertion rod 6 is inserted into the corresponding slot 4. The quick fixation of the tripod 3 can be achieved through the insertion of the insertion rod 6 into the slot 4. The outer surface of each insertion rod 6 is slidably connected to the support plate 1. When the insertion rod 6 is pulled, the insertion rod 6 will slide vertically along the corresponding connecting frame 5. A first spring 7 is sleeved on the outer surface of each insertion rod 6. The top end of each first spring 7 is fixedly connected to the corresponding connecting frame 5, and the other end is fixedly connected to the corresponding insertion rod 6. Specifically, by pulling the insertion rod 6, the insertion rod 6 will be lifted above the corresponding T-shaped groove 2. At this time, the first spring 7 starts to compress.

[0025] In this embodiment, a support frame 11 is provided above the support plate 1. A screw rod 8 is threadedly connected to the inner wall of the support frame 11.

The inner wall of each fixing ring 18 is rotatably connected with a first pulley 19. When the sampling gun passes through the fixing ring 18, it will contact the corresponding first pulley 19. The rotation of the first pulley 19 can reduce the friction force received by the sampling gun. A second pulley 23 is arranged above each first pulley 19. Specifically, the sampling gun can be quickly clamped through the mutual cooperation of the first pulley 19 and the second pulley 23.

[0030] Looking back Figure 3 , a sliding rod 20 is slidably connected to the inner wall of each fixing ring 18. The sliding rod 20 can slide vertically along the corresponding fixing ring 18. The bottom end of each sliding rod 20 is fixedly connected with a U-shaped plate 22. The second pulley 23 will be driven to slide vertically by the corresponding U-shaped plate 22 during the vertical sliding of the sliding rod 20. The inner wall of each U-shaped plate 22 is rotatably connected with the corresponding second pulley 23. A third spring 21 is sleeved on the outer surface of each sliding rod 20.
