[0015] Reference Figure 1-3A small-diameter high-energy detonator for upward blastholes comprises a shell 1, a rack 2 and a clamping ring 3. The shell 1 is provided with symmetrically arranged passage grooves 4. Mounting grooves 5 are provided at positions corresponding to the passage grooves 4 inside the shell 1. Symmetrically arranged round rods 6 are rotatably connected inside the two mounting grooves 5. A plurality of round rods 6 are fixedly connected with gears 7. A plurality of round rods 6 are fixedly connected with mounting rings 8 at positions corresponding to the bottom ends of the gears 7. A plurality of mounting rings 8 are fixedly connected with symmetrically arranged top rods 9. The two clamping rings 3 are fixedly connected with symmetrically arranged springs 10 on the opposite sides thereof. The two clamping rings 3 are fixedly connected with symmetrically arranged mounting frames 11 on the opposite sides thereof. Pressure-bearing rods 12 are fixedly connected to the two mounting frames 11. Moving rings 13 are fixedly connected with the opposite sides of the two racks 2.

[0016] Furthermore, the two passage slots 4 are both fixedly connected with symmetrically arranged guide rods 14 , and the racks 2 are both slidably connected to the guide rods 14 , so that the guide rods 14 are convenient for guiding the movement of the racks 2 .

[0017] Furthermore, opposite sides of the two racks 2 pass through the passage slot 4 , and the racks 2 are meshed and connected with the gear 7 , so that the racks 2 can drive the gear 7 to rotate.

[0018] Furthermore, the passage groove 4 and the installation groove 5 are both in a communicating state, and the push rod 9 is in contact with the pressure-bearing rod 12 , so that the push rod 9 can easily drive the clamping ring 3 to move through the pressure-bearing rod 12 .

[0019] Furthermore, the springs 10 are fixedly connected to the inner wall of the housing 1 , and the springs 10 facilitate the resetting movement of the clamping ring 3 .

[0020] When the device is in use, the staff can directly hold the corresponding position of the moving ring 13 on the shell 1 with one hand. At this time, the staff tightens their fists to squeeze the two moving rings 13. The two moving rings 13 will move toward the middle direction under the squeezing. The movement of the two moving rings 13 will drive the rack 2 to move. The movement of the two racks 2 will drive the gear 7 to rotate. At this time, multiple gears 7 will drive the round rod 6 to rotate. The rotation of the round rod 6 will drive the installation ring 8 to rotate. When the installation ring 8 rotates, it will drive the push rod 9 to rotate together. At this time, each push rod 9 will rotate in a direction away from each other, and the bearing opening and closing rotation is similar to the opening of the double blades of scissors. Then, each rotating push rod 9 will squeeze the pressure rod 12. The pressure rod 12 will be squeezed and the squeezing force will be transmitted to the mounting frame 11 through the mounting frame 11. Give the clamping ring 3, at this time the two clamping rings 3 will move in the direction away from each other, the movement of the clamping ring 3 will squeeze and shrink the spring 10, at this time the space between the clamping rings 3 is expanded, the detonator can be directly inserted between the two clamping rings 3, and then the two moving rings 13 are loosened, each spring 10 will reset each mechanism, the two clamping rings 3 will clamp and fix the detonator, when the clamping ring 3 clamps the detonator, the moving ring 13 is tightly fitted with the outer wall of the shell 1, and the diameter of the blasting hole is larger than the diameter of the entire blasting tool shell 1, so the entire blasting tool can be smoothly driven into the inside of the blasting hole, and then the entire detonator is placed at the location where blasting is required, and the igniter is controlled by the controller for electronic ignition to ignite the fuel inside, melt the partition plate, and then detonate the detonator.
