[0003] At present, in order to achieve a better polishing effect, energy-gathering devices are used for blasting. During the blasting process, the vibrations generated by the explosions of explosives in sequence cause the positions of the explosives to shift, thus affecting the blasting effect. In addition, the explosives in the prior art are fixed by cutting them first and then installing them, which is complicated, time-consuming and labor-intensive. Utility Model Content

At the same time, the first extrusion plate 44 is squeezed by the shaped explosive and moves backward, and the second extrusion spring 43 squeezes the first extrusion plate 44, so that the first extrusion plate 44 fixes the upper end of the shaped explosive, thereby improving the fixing effect of the device, and preventing the shaped explosive in the fixed cylinder 1 from falling when the explosive hole is downward;

[0024] The base device 5 comprises a bottom plate 51, and a through hole 52 is formed in an annular manner at equal intervals on the side wall of the bottom plate 51. A fixing rod 55 is slidably connected to the inner wall of the through hole 52. A telescopic spring 53 is sleeved on the fixing rod 55. A second extrusion plate 54 is fixedly connected to the inner end of the fixing rod 55. The clamping rod 2 is arranged on the upper surface of the bottom plate 51. The bottom plate 51 is clamped with the clamping groove 6 at the lower end of the fixed cylinder 1 through the clamping rod 2. After the shaped explosive is installed into the fixed cylinder 1, the shaped explosive is placed in the middle position through the guide ring 3. After adjusting the blasting direction, the shaped explosive is pressed to squeeze the second extrusion plate 54. The second extrusion plate 54 drives the fixing rod 55 to move outward. The fixing rod 55 is inserted into the inner wall of the explosive hole. At the same time, the telescopic spring 53 is squeezed. When the shaped explosive is pressed to the bottom, the telescopic spring 53 squeezes the second extrusion plate 54 so that the second extrusion plate 54 has the effect of clamping and fixing the shaped explosive, thereby avoiding the position deviation of the explosive, thereby improving the blasting effect.

[0025] The two ends of the second extrusion spring 43 are respectively connected to the inner wall of the top plate 41 and the outer side wall of the first extrusion plate 44, and the two ends of the telescopic spring 53 are respectively connected to the side wall of the fixed cylinder 1 and the outer side wall of the second extrusion plate 54.

By configuring the outer end of the fixing rod 55 as a cone, the fixing rod 55 reduces the resistance encountered by the fixing rod 55 in the inner wall of the insertion hole.

[0027] Working principle: when the device is working, the fixed cylinder 1 is engaged with the base device 5, and when the clamping rod 2 reaches the clamping groove 6, the clamping block 9 is squeezed, so that the clamping block 9 moves backward to squeeze the first squeezing spring 8.

Through the clamping rod 2 and the clamping groove 6, the device can adjust the length of the fixed cylinder 1 according to actual needs, which saves time and effort for fixing the explosive and improves the practicality of the device. Moreover, by installing the shaped explosive into the fixed cylinder 1 and then putting it into the explosive hole, the explosive is protected to avoid damage caused by friction between the explosive and the hole wall;

The fixing rod 55 is inserted into the inner wall of the explosive hole. At the same time, the telescopic spring 53 is squeezed. When the shaped charge is pressed to the bottom, the telescopic spring 53 squeezes the second squeezing plate 54 so that the second squeezing plate 54 has a clamping and fixing effect on the shaped charge, thereby preventing the explosive position from shifting, thereby improving the blasting effect.

At the same time, the first squeezing plate 44 is squeezed by the shaped charge and moves backward, and the second squeezing spring 43 squeezes the first squeezing plate 44, so that the first squeezing plate 44 fixes the upper end of the shaped charge, thereby improving the fixing effect of the device and preventing the shaped charge in the fixed cylinder 1 from falling when the explosive hole is downward.
