[0007] Preferably, the fixed pipe is rotatably connected with two adjusting rings, and the adjusting ring is fixedly connected with three adjusting blocks.

[0008] The effect achieved by the above components is that counterclockwise rotation of the adjusting ring can drive the three adjusting blocks to synchronously push the slide rods to slide, so that clamping operation is more convenient.

[0009] Preferably, a first spring is sleeved on the slide rod, one end of the first spring is fixedly connected to the clamping block, and the other end of the first spring is fixedly connected to the fixed tube.

[0010] The effect achieved by the above components is that during clamping, the three first springs are in a stretched state, so that when the adjusting ring is rotated clockwise, the three slide rods slide outward under the action of the elastic force of the first spring, facilitating disassembly and replacement of the damaged detonator.

[0011] Preferably, a bolt is threadedly inserted on one adjusting ring, and a round rod is fixedly connected to the two adjusting rings.

[0012] The effect achieved by the above components is that one adjusting ring can be rotated to drive the two adjusting rings to be synchronously adjusted, so that operation is more convenient, and after the position is adjusted, the bolt can be rotated to abut against the surface of the fixed tube to limit the adjusting ring.

[0020] The effect achieved by the above components is as follows: when the two sliders slide close to each other, they will compress the second spring and cause it to deform, absorbing some kinetic energy. Then, when it rebounds and resets, it will release energy. At this time, the damping rod synchronously rubs internally to convert the energy released by the second spring into heat energy, thereby reducing the amplitude and time of oscillation and further improving the buffering effect.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a fixed structure, the detonator is inserted into the fixed tube, and then the sliding rod makes three clamping blocks clamp one part of the detonator as a group, and six blocks in two groups to make the limiting more stable. The rubber pad can prevent the detonator from being damaged by rigid contact with the clamping blocks. After the detonator is installed, the fixed tube is placed in the blast hole, and the fixed blocks are installed at the hole opening by two screws. This can realize the quick installation of the detonator, thereby avoiding the situation that the current method requires filling the blast hole with cement to position the detonator after it is placed in the blast hole. The cement usually needs to be solidified before the blasting operation can be carried out, which leads to the extension of the construction period. Attached Figure Description

[0027] Example 1, such as Figure 1 As shown, a detonator fixing device includes a fixing tube 1, one end of which is fixedly connected to a fixing block 2, and two screws 3 are threadedly inserted into the fixing block 2.

[0028] Reference Figure 1 and Figure 3The fixed pipe 1 is provided with a fixing structure 4, which is mainly composed of six slide rods 41. The six slide rods 41 are slidably inserted into the fixed pipe 1. One end of the slide rod 41 is fixedly connected with a clamping block 42. The clamping block 42 is fixedly connected with a rubber pad 43. The detonator is inserted into the fixed pipe 1. Then, the slide rod 41 is slid to make three clamping blocks 42 form a group to clamp one part of the detonator. Six clamping blocks form two groups to make the limiting more stable. The rubber pad 43 can prevent the rigid contact between the detonator and the clamping block 42 from damaging the detonator. After the detonator is installed, the fixed pipe 1 is placed in the blasting hole. The fixing block 2 is installed at the hole opening through the two screw rods 3. The detonator can be quickly installed, so that the detonator is positioned by filling cement in the blasting hole. The cement needs to be solidified before the blasting operation, which prolongs the construction period. The fixed pipe 1 is rotatably connected with two adjusting rings 44. The adjusting ring 44 is fixedly connected with three adjusting blocks 45. Counterclockwise rotation of the adjusting ring 44 can drive the three adjusting blocks 45 to synchronously push the slide rod 41 to slide, so that the clamping operation is more convenient. The slide rod 41 is sleeved with a first spring 46. One end of the first spring 46 is fixedly connected with the clamping block 42. The other end of the first spring 46 is fixedly connected with the fixed pipe 1. During the clamping process, the three first springs 46 are in a stretched state. Therefore, when the adjusting ring 44 is rotated clockwise, the three slide rods 41 will slide outward under the action of the elastic force of the first spring 46. The damaged detonator can be conveniently disassembled and replaced. The adjusting ring 44 is threadedly inserted with a bolt 47. The two adjusting rings 44 are fixedly connected with a round rod 48. One adjusting ring 44 is rotated to drive the two adjusting rings 44 to be synchronously adjusted, so that the operation is more convenient. After the position is adjusted, the bolt 47 is rotated to abut against the surface of the fixed pipe 1 to limit the adjusting ring 44.

[0029] Referring to Figure 4The fixed pipe 1 is provided with a buffer structure 5, which is mainly composed of a baffle 51. When debris or other impurities in the blasting hole fall down, the baffle 51 will block to prevent direct impact on the fixed pipe 1, thereby preventing the danger of causing impact on the detonator. The baffle 51 is fixedly connected with a buffer pad 52 made of rubber. When the baffle 51 is impacted from outside, the buffer pad 52 will deform to absorb part of kinetic energy, thereby achieving the buffering effect. The fixed pipe 1 is provided with a sliding groove 53, and two sliding blocks 54 are slidingly connected in the sliding groove 53. The sliding blocks 54 are rotatably connected with connecting rods 55. One end of the connecting rods 55 is rotatably connected with the baffle 51. When the baffle 51 is impacted, it will press downward on the two connecting rods 55, so that the two sliding blocks 54 slide close to each other. The two sliding blocks 54 are fixedly connected with a damping rod 57. The damping rod 57 is sleeved with a second spring 56. The two ends of the second spring 56 are fixedly connected with the two sliding blocks 54. When the two sliding blocks 54 slide close to each other, the second spring 56 will be squeezed and contracted. The deformation of the second spring 56 will absorb part of kinetic energy, and then rebound to release energy. At this time, the damping rod 57 synchronously converts the energy released by the second spring 56 into heat energy through internal friction, thereby reducing the amplitude and time of vibration, and further improving the buffering effect.

[0030] The working principle is that the detonator is inserted into the fixed tube 1, then the slide rod 41 is slid to make the three clamping blocks 42 clamp a part of the detonator in a group, six groups make the limiting more stable, and the rubber pad 43 can prevent the rigid contact of the detonator and the clamping block 42 from causing damage to the detonator, after the detonator is installed, the fixed tube 1 is placed in the blasting hole, and the fixed block 2 is installed at the hole opening through the two screw rods 3, so that the detonator can be quickly installed, thereby avoiding the situation that the detonator is placed in the blasting hole, and the cement needs to be filled in the blasting hole to position the detonator, and the filled cement generally needs to be waited to solidify before the blasting operation is performed, so that the construction period is prolonged, counterclockwise rotation of the adjusting ring 44 can drive the three adjusting blocks 45 to synchronously push the slide rod 41 to slide, so that the clamping operation is more convenient, during the clamping process, the three first springs 46 are in the stretched state, so when the adjusting ring 44 is rotated clockwise, the three slide rods 41 will slide outward under the action of the elastic force of the first spring 46, facilitating the disassembly and replacement of the damaged detonator, the two adjusting rings 44 can be synchronously adjusted by rotating one adjusting ring 44, so that the operation is more convenient, and after the position is adjusted, the screw 47 can be rotated to abut against the surface of the fixed tube 1 to limit the adjusting ring 44, when the debris and other sundries in the blasting hole fall down, the baffle 51 will be blocked to prevent direct impact on the fixed tube 1, which can cause danger to the detonator, when the baffle 51 is impacted from the outside, the buffer pad 52 will be deformed to absorb part of kinetic energy, so as to realize the buffering effect, when the baffle 51 is impacted, it will press downward on the two connecting rods 55, so that the two sliding blocks 54 slide towards each other, when the two sliding blocks 54 slide towards each other, the second spring 56 will be extruded and contracted, the deformation of the second spring 56 will absorb part of kinetic energy, and then the elastic recovery will release energy, at this time, the damping rod 57 synchronously internally rubs to convert the energy released by the second spring 56 into heat energy, so as to reduce the vibration amplitude and time, and further improve the buffering effect.
