[0032] A fixed column 3, the fixed column 3 is slidably clamped on the circumferential inner wall of the hollow cylinder 1;

[0033] The adjusting mechanism 5 has slots 6 on both sides of the inner wall of the strip opening 2. The adjusting mechanism 5 is fixedly mounted on the outer wall of one side of the fixing column 3 near the bottom, and the adjusting mechanism 5 is slidably connected to the inner wall of the strip opening 2, and both ends of the adjusting mechanism 5 are in contact with the slots 6;

[0034] The digging mechanism 4 is installed on the top outer wall of the fixed column 3.

[0035] As can be seen from the above, when in use, the firefighter holds the hollow tube 1 and digs away burning objects, obstacles, coverings, etc. through the digging mechanism 4 at the front end of the fixed column 3. The length of the device is adjusted by the adjusting mechanism 5 as needed, thereby facilitating the development of fire rescue operations.

[0036] Specifically, the adjustment mechanism 5 includes a slider 504, which is fixedly installed on the outer wall of one side of the fixed column 3 near the bottom. The slider 504 is slidably connected to the inner wall of the strip opening 2. A push rod 501 is installed on the outer wall of one side of the slider 504, and the slider 504 is connected to the inside of the push rod 501.

[0037] As can be seen from the above, when the length of the device needs to be adjusted, the push rod 501 can be pushed out to push out the fixing column 3 .

[0038] Specifically, connecting plates 505 are slidably installed on both sides of the slider 504 and the push rod 501 near the center line, and multiple springs 506 are fixed on the outer walls of the two connecting plates 505 on the opposite sides. Paddles 502 are fixed on the outer walls of one side of the two connecting plates 505. The two paddles 502 are slidably connected to the outer walls of the two sides of the push rod 501 respectively. A lever 503 is installed at one end of the two paddles 502, and the lever 503 is located on the outside of the push rod 501. Connecting rods 507 are fixed at the outer walls of one side of the two connecting plates 505 away from the paddles 502. A clamping block 508 is fixedly installed on one end of the two connecting rods 507. The clamping block 508 is slidably connected to the outer wall of the slider 504, and one end of the clamping block 508 is clamped on the inner wall of the slot 6.

[0039] As can be seen from the above, when the length needs to be adjusted, the firefighter holds the hollow tube 1 and presses the lever 503 with one hand, so that the paddle 502 is pressed into the push rod 501, so that the two connecting plates 505 are close to each other, the spring 506 is compressed, and the two connecting rods 507 are close to each other, and the two clamping blocks 508 are withdrawn from the clamping slot 6. Then, the push rod 501 is pushed to drive the slider 504 to slide in the strip mouth 2, thereby pushing the fixed column 3 out, thereby changing the length of the device. After the length adjustment is completed, the lever 503 is released, that is, the paddle 502 and the clamping block 508 rebound, and the clamping block 508 is clamped into the clamping slot 6 again for fixation, thereby changing the length of the device and fixing the fixed column 3 again.

[0040] Specifically, the digging mechanism 4 includes a sleeve 401, which is sleeved on one end of the fixed column 3, a support rod 402 is fixedly installed on one end of the sleeve 401, and iron hooks 403 are fixedly installed on one end of the support rod 402 near both sides.

[0041] As can be seen from the above, the iron hook 403 can be used to dig out burning objects, obstacles, coverings, etc. to prevent objects from smoldering, and can also be used to remove ceilings and hook and pull electric wires at fire scenes.

[0042] Working principle: When in use, the firefighter holds the hollow tube 1 and uses the digging mechanism 4 at the front end of the fixed column 3 to dig out burning objects, obstacles, coverings, etc., and adjusts the length of the device through the adjustment mechanism 5 as needed. The firefighter holds the hollow tube 1 and presses the lever 503 with one hand to press the paddle 502 into the push rod 501, so that the two connecting plates 505 are close to each other, the spring 506 is compressed, and then the two connecting rods 507 are close to each other, and the two blocks 508 are withdrawn from the slot 6. Then, the push rod 501 is pushed to drive the slider 504 to slide in the strip mouth 2, thereby pushing the fixed column 3 out, thereby changing the length of the device. After the length adjustment is completed, the lever 503 is released, that is, the paddle 502 and the block 508 rebound, and the block 508 is again inserted into the slot 6 for fixation, thereby changing the length of the device and fixing the fixed column 3 again.
