[0019] In the embodiment, the lengths of the plastic pipe 104 and the exhaust pipe 110 should be designed flexibly according to the drilling depth of the rock, in operation, the plastic pipe 104 is arranged through the center of the paper roll 106, and the support rod 112 is clamped into the limiting slot 113 on the paper roll 106, the design of the support rod 112 and the limiting slot 113 can ensure the connection of the plastic pipe 104 and the paper roll 106, so that when the plastic pipe 104, the paper roll 106 and the sealing bag 107 are placed in the drilling hole together, the separation of them is avoided, the damage of the sealing bag 107 caused by the falling force is reduced, and the use effect of the device is improved.

[0020] The sealing bag 107 is sleeved outside the paper roll 106, one end is sealed by transparent adhesive, and the other end is packaged on the plastic pipe 104 by transparent adhesive, so as to realize sealing operation. One end of the hollow guide rod 208 is inserted into the inner cavity top end of the plastic pipe 104, and the air inlet pipe at the top of the hollow guide rod 208 is connected to the gas supply device. After starting the gas supply device, the gas passes through the inside of the hollow guide rod 208 and fills the air bag ball 209, so that the air bag ball 209 is inflated and tightly attached to the inner wall of the plastic pipe 104, realizing the connection of the plastic pipe 104 and the hollow guide rod 208. Then, the control valve is closed, the gas supply device is disconnected from the air inlet pipe at the top end of the hollow guide rod 208, and the hollow guide rod 208 is placed between the two groups of arc-shaped plates 205. By rotating the screw rod 204, the two groups of connecting plates 207 are threadedly connected to the screw rod 204 through the threaded holes, and the connecting plates 207 are driven to move away from or close to each other. One side of the connecting plate 207 is in contact with the inner side wall of the U-shaped plate 203, so as to limit the movement of the connecting plate 207 and ensure the stability of the movement. Through the movement of the connecting plate 207, the two groups of arc-shaped plates 205 are driven to move synchronously, and the hollow guide rod 208 is clamped. Until the ball 206 on the arc-shaped plate 205 contacts the surface of the hollow guide rod 208, the annular structure formed when the two groups of arc-shaped plates 205 are attached can limit the hollow guide rod 208, so that it is more stable during downward movement. The ball 206 arranged on the surface of the arc-shaped plate 205 can reduce the friction when the hollow guide rod 208 moves downward, improve the smoothness of the movement, loosen the hollow guide rod 208, and continuously move downward. The plastic pipe 104, the paper roll 106 and the sealing bag 107 are placed in the drill hole, and the arrangement of the guide mechanism 2 can ensure that the plastic pipe 104, the paper roll 106 and the sealing bag 107 are stably moved into the rock drill hole. Compared with the manual method, the contact between the sealing bag 107 and the rock drill hole wall is avoided, the friction damage is reduced, and the sealing cavity formed by the sealing bag 107 is effectively ensured, thereby further improving the use effect of the device. In use, first, open the control valve (not shown in the figure), release the gas in the air bag ball 209, discharge through the air inlet pipe, so that the air bag ball 209 is in a deflated state, thereby releasing the connection between the hollow guide rod 208 and the plastic pipe 104. Then, pull the hollow guide rod 208 to disconnect one end from the plastic pipe 104, and move the guide mechanism 2 to an area away from the plastic pipe 104; Next, the ignition head 108 is placed about 50 cm away from the sealed bag 107, two iron wires 109 are connected to the positive and negative electrodes of the ignition head 108, and then the other ends of the iron wires 109 are threaded through the exhaust pipe 110 and located inside the paper roll 106. During this process, marks are made on the surface of the iron wires 109 using a marker pen. By pulling the two sets of pressing plates 302 away from each other and stretching the springs 304 and telescopic rods 303, a gap is created between the pressing plates 302 and the fixed blocks 301, allowing one end of the iron wire 109 to pass through the arc-shaped slots where the pressing plates 302 and the fixed blocks 301 are close to each other. The iron wire 109 is continuously released until the clamping parts of the pressing plates 302 and the fixed blocks 301 correspond to the marked points. At this time, one end of the iron wire 109 is threaded through the exhaust pipe 110 and extends out through the bottom end. After releasing the pressing plates 302, the springs 304 contract and reset, causing the fixed blocks 301 to adhere. By pressing the pressing plates 302 and the fixed blocks 301, the position of the iron wire 109 is fixed to prevent movement and ensure that the head ends of the two iron wires 109 are close together. A partition 306 is installed inside the exhaust pipe 110 to separate the two iron wires 109 and prevent them from touching each other; A buckle 305 is provided on the pressing plate 302. While pulling the pressing plate 302, the buckle 305 is rotated to a certain angle and placed outside the exhaust pipe 110. By blocking the buckle 305, the pressing plate 302 is locked, so that it is not necessary to hold the pressing plate 302 during the insertion of the iron wire 109, thereby improving the use effect of the structure. After the pressing plate 302 and the fixed block 301 clamp the iron wire 109, the buckle 305 is rotated to be out of position with the outer side of the exhaust pipe 110, thereby unlocking the pressing plate 302; By providing the anti-movement mechanism 3, the positions of the two iron wires 109 can be locked when they pass through the exhaust pipe 110, preventing the ends from being too far apart and ensuring that the electric spark generated by the arc discharge can be achieved, and the electric spark end of the iron wire 109 remains stable inside the paper roll 106; Subsequently, one end of the gas inlet pipe 103 is connected to the top end of the plastic pipe 104 through a clamp. The valve body of the liquid oxygen tank 102 is opened, and oxygen is filled into the plastic pipe 104 through the gas inlet pipe 103 and discharged through the exhaust hole 105 into the sealed cavity formed by the sealed bag 107. This process can last for 3-10 minutes. Due to the provision of the exhaust pipe 110, as the oxygen is continuously filled, the oxygen in the sealed bag 107 is moderately retained and discharged through the exhaust pipe 110 at a small rate, thereby achieving an automatic pressure relief function; After the oxygen is filled, the connection between the gas inlet pipe 103 and the plastic pipe 104 is released by releasing the clamp. The plastic pipe 104 is provided with a one-way inlet valve, and one end of the plastic pipe 104 does not discharge. Then, the ignition head 108 is powered on, and the arc discharge of the two iron wire lines 109 generates an electric spark, which is combusted by high-purity oxygen in the sealed bag 107, and the gas expands to form an explosion, which is low in pollution. If a "dud" phenomenon occurs, the exhaust pipe 110 is arranged so that when a blind shot is generated, it does not need to be handled, but the liquid oxygen is converted into oxygen and discharged, avoiding safety risks caused by handling blind shots; The present application completely abandons the traditional flammable and explosive explosive by sealed liquid oxygen gas explosion, completely eliminates the major safety accidents caused by accidental explosion of explosives in the production, transportation, storage and use process, provides essential safety protection for the life safety of operating personnel and the surrounding environment, reduces the safety management cost and potential accident compensation risk, at the same time, compared with the harmful gases such as carbon monoxide, nitrogen oxides and sulfides generated by explosive explosion and a large amount of dust, the atmospheric pollution is significantly reduced; and compared with the strong vibration and noise generated by explosive explosion, the energy release generated by pure oxygen expansion is more controllable, effectively reducing the interference to surrounding buildings and residents' life, helping to maintain ecological balance, and meeting the sustainable development concept. The present application can also efficiently convert electric energy into mechanical energy, and the energy utilization rate is significantly higher than that of traditional explosive blasting, reducing energy waste. In addition, there is no need for complex explosive transportation, storage and management system, which reduces the operating cost, at the same time reduces the additional expenditure caused by environmental governance, equipment repair and other aspects, improves the economic benefit of the project. Convenient operation improves the overall operation efficiency.

[0021] It should be noted that: the anti-movement mechanism 3 can also be wound by multiple strands of iron wire lines 109 at the end away from the ignition head 108, and then the wound multiple strands of iron wire lines 109 are attached together, and then the two groups of iron wire lines 109 are wound by insulating glue, and then the two groups of iron wire lines 109 are inserted through the exhaust pipe 110 and located in the paper roll 106 to realize the function of generating electric spark by arc discharge at the tip.
