[0030] When the auxiliary tool is used, the top ends of the two clamping plates 205 are first aligned with the gap of the stone slab after the earthquake, and then the expansion mechanism 2 is operated to connect the connecting pipe to the main rod 1, and the other end of the connecting pipe is connected to the air pump. The air pump inputs air flow into the cylinder 202 to make the output shaft of the cylinder 202 extend, thereby pushing the transmission shaft 203 to move toward the gap of the stone slab, and the movement of the transmission shaft 203 pushes the second connecting block 204 to move, thereby driving the two clamping plates 205 to move toward the gap of the stone slab, so that the tips of the two clamping plates 205 extend into the gap of the stone slab, and the stone slab is pushed out from the rocks to create a space, which is convenient for rescue personnel to carry out rescue work through the space; because the two clamping plates 205 slide through the connecting shaft 208 Connected to the limiting groove 207, the two splints 205 move away from the main rod 1, which will drive the connecting shaft 208 to move synchronously, thereby changing the position of the connecting shaft 208 on the limiting groove 207, thereby driving the two splints 205 away from each other, expanding the distance between the two splints 205, and then further expanding the space in the stone slab gap by expanding the spacing between the two splints 205, thereby facilitating the subsequent rescue work. At the same time, when the stone slab gap is effectively supported by the rescue personnel, the rescue personnel can control the distance between the two splints 205 to bring the required items into the deep of the gap, or clear out the internal rocks, further improving the practicality of the auxiliary tool.

[0031] Reference Figure 2 In this embodiment, the two limit grooves 207 are connected in a straight line and an arc shape from the main rod 1 to the splint 205. The end of the arc away from the main rod 1 expands toward the outside of the limit plate 206, so that when the two splints 205 move away from the main rod 1, they will first pass through the straight end, so that the two splints 205 maintain the initial distance and move a distance, so that the tips of the two splints 205 can enter the stone crevice. Then the connecting shaft 208 moves to the arc of the limit groove 207, and at this time, the two splints 205 are pushed away from each other, thereby controlling the distance between the two splints 205, thereby achieving the purpose of expanding the space at the stone crevice.

[0032] Reference Figure 4 In this embodiment, a first connecting groove 209 is provided at one end of the two splints 205 close to the main rod 1, and a connecting strip 210 is installed on the second connecting block 204. The connecting strip 210 is slidably adapted on the first connecting groove 209, so that the two splints 205 can be slidably connected to the second connecting block 204 through the adaptability of the connecting strip 210 and the first connecting groove 209. When the two splints 205 move, they are restricted by the connecting shaft 208 and the limit groove 207, so that the two splints 205 can move away from each other through their sliding connection to the second connecting block 204.

[0033] Reference Figure 3In this embodiment, a connecting hole 211 is provided on the first connecting block 201, and the connecting hole 211 is adapted to the transmission shaft 203, so that one end of the transmission shaft 203 can pass through the first connecting block 201 through the connecting hole 211 and connect with the second connecting block 204, so that when the transmission shaft 203 moves, it can drive the second connection 204 to move synchronously, thereby completing the smooth transmission of power.

[0034] Reference Figure 4 In this embodiment, the two splints 205 each include a base plate 212 slidably mounted on the second connecting block 204, a clamp 213 is slidably connected to the base plate 212, and the connection between the clamp 213 and the base plate 212 is connected by bolts, so that the splint 205 can be constructed in the form of an interactive connection between the base plate 212 and the clamp 213, so that rescuers can freely replace the clamp 213 on the splint 205 when facing different rescue situations, thereby meeting different needs of rescue work and further improving the practicality of the auxiliary tool.

[0035] Reference Figure 5 In this embodiment, a slider 214 is installed on the second connecting block 204, and a slide groove 215 is opened on the limiting plate 206. The slider 214 is slidably adapted on the slide groove 215, so that the second connecting block 204 can be slidably connected to the limiting plate 206 through the adaptability of the slider 214 and the slide groove 215, so that the second connecting block 204 can be firmly slidably connected to the limiting plate 206. At the same time, the slider 214 and the slide groove 215 limit the position of the moving direction of the second connecting block 204, so that the second connecting block 204 can always maintain an accurate moving direction.

[0036] Reference Figure 2 In this embodiment, a searchlight 3 is installed at one end of the limit plate 206 away from the main pole 1, so that when the rescue position is insufficiently lit, the rescue personnel can observe the rescue area through the searchlight 6 installed on the moving block 307, thereby clarifying the specific steps of the rescue and improving the rescue efficiency.

[0037] Reference Figure 1 In this embodiment, an extension rod 4 is movably installed at one end of the main rod 1 away from the splint 205. The extension rod 4 is retractable, so that the auxiliary tool can quickly install the extension rod 4, thereby effectively increasing the use distance of the auxiliary tool and facilitating rescue work deep in the crevices.

[0038] Reference Figure 6-7In this embodiment, the dust removal mechanism 5 includes two connecting rods 501 rotatably connected to the transmission shaft 203, the two connecting rods 501 are distributed on both sides of the transmission shaft 203 and are in the same plane as the chuck 213, the two connecting rods 501 are each provided with a second air delivery hole 502, the two connecting rods 501 are each provided with a receiving groove 503 at one end away from the cylinder 202, air bags 504 are installed in the two receiving grooves 503, and the tops of the two air bags 504 are each provided with a plurality of exhaust holes 509, the cylinder 202 is provided with two first air delivery holes 505 and a third air delivery hole 508, the third air delivery hole 508 runs through one side of the main rod 1 and is connected to one of the first air delivery holes 505, the two first air delivery holes 505 are each connected to an air delivery pipe 506 at one end close to the connecting rod 501, and the two air delivery pipes 506 are connected to the corresponding second air delivery holes 502.

[0039] When the cylinder 202 is running, the cylinder 202 pushes the transmission shaft 203 to move toward the chuck 213, so that the transmission shaft 203 can drive the two connecting rods 501 to move synchronously to the outside of the main body 1, so that the airbag 504 is on both sides of the chuck 213. When the cylinder 202 is running, the airflow enters the cylinder 202 through the third air delivery hole 508, and then enters the two first air delivery holes 505, and then enters the corresponding air delivery pipe 506, the second air delivery hole 502, and the airbag 504 in turn from the two first air delivery holes 505. , so that air is injected into the two airbags 504, causing the airbags 504 to expand. When the airbags 504 expand to contact the two clamps 213 that are far away from each other, the two clamps 213 squeeze the airbags 504, causing the airflow in the airbags 504 to be discharged from the plurality of exhaust holes 509. The discharged airflow impacts small particles of gravel and dust, thereby simultaneously achieving the effect of cleaning the dust in the gravel pile, making it easier for rescue personnel to observe the internal conditions of the rescue site more clearly, thereby improving the rescue efficiency.

[0040] Reference Figure 6 In this embodiment, two movable grooves 507 are provided on the main rod 1, and the openings of the two movable grooves 507 at one end close to the chuck 213 are both inclined. The two connecting rods 501 are slidably fitted in the corresponding movable grooves 507, so that the movable grooves 507 can provide sufficient space for the movement of the two connecting rods 501, so that the connecting rods 501 can move to the outside of the main rod 1 through the movable grooves 507; by setting the opening ends of the movable grooves 507 close to the chuck 213 to an inclined shape, when the two connecting rods 501 move toward the chuck 213, the top ends of the two connecting rods 501 will contact the inclined openings, thereby causing the moving direction of the connecting rods 501 to be offset, so that the connecting rods 501 can be accurately moved to the outside of the main rod 1 for subsequent dust removal work.
