A resistance block 16 is movably provided between the left end of the bottom surface of the circular plate at the upper end of the top column 17 and the base 18. The lower end of the resistance block 16 is integrally connected with a slider 15. Four groups of moving wheel mounting seats 21 distributed in a circular array are fixedly welded on the lower surface of the base 18. Four groups of outer holes 12 distributed in a circular array are provided near the outer ring of the base 18. The outer holes 12 penetrate the upper and lower surfaces of the base 18 at the same time. A ground suction nail 11 is movably penetrated in the outer hole 12. An outer hexagonal screw head 23 is fixedly welded on the upper end of the ground suction nail 11. The outer hexagonal screw head 23 is fixedly fixed to the bottom of the magnetic suction block 9 by suction. The magnetic suction block 9 is fixed on the lower surface of the rotation limit plate 8.

[0025] The fixing edge 4 is in a semicircular ring structure and is fixed to the surface of the metal support column 6 by screws.

[0026] The explosion-proof frame 5 is a concave shell-like structure, and the explosion-proof frames 5 on the left and right sides form a rectangular shell-like structure without a lower surface.

[0027] The abutment block 16 is in a trapezoidal structure. A surface of the abutment block 16 close to the top column 17 is an inclined surface, and the inclined surface is inclined from the upper end to the lower end of the abutment block 16 toward the lower end of the top column 17 .

[0028] The slider 15 is in a T-shaped structure, and the slider 15 is slidably arranged in a matching slide groove 14 on the surface of the base 18 .

The limit nut 7 is connected to the upper end of the shaft rod 22 through threaded cooperation, and the shaft rod 22 is fixedly welded to the upper surface of the base 18.

[0032] Working principle: First, move the device to a fixed position through the moving wheel 13, manually slide the resistance block 16 so that the resistance block 16 moves out from under the upper plate of the top column 17, and the top column 17 loses its supporting function and drops in the inner hole 20. The counterweight block 19 at the lower end of the top column 17 fits with the ground, playing the role of a preliminary positioning device, so that the device is not easily displaced and rotated during the fixing process;

[0033] After that, the rotation limit plate 8 is twisted to move the rotation limit plate 8 to one end close to the metal support column 6. The outer hexagonal screw head 23 loses the adsorption effect of the magnetic block 9 at this time and can be lowered. Then, the ground-absorbing nail 11 is screwed into the ground with a suitable hexagonal wrench. The outer ring fixing sleeve of the ground-absorbing nail 11 is provided with an outer ring auger 10, which increases the fixing strength between the ground-absorbing nail 11 and the ground.

[0034] Afterwards, the left and right explosion-proof frames 5 are installed on the metal support column 6, and fixed to the metal support column 6 by screws on the fixing edge 4 at the upper end of the explosion-proof frame 5. The connection structure is stable and easy to disassemble and assemble. The explosion-proof frame 5 plays a role in protecting its internal devices;

[0035] When disassembling for recycling, first remove the explosion-proof frame 5, then unscrew the ground nails 11 in sequence, push the resistance block 16 to reset, and the resistance block 16 is inserted between the upper plate of the top column 17 and the base 18 through the inclined surface at the right end, so that the top column 17 gradually rises, the counterweight block 19 is separated from the ground, and the ground nails 11 are attracted to the corresponding magnetic block 9 again, and the ground nails 11 are separated from the ground. At this time, the device can be smoothly moved by the moving wheel 13, and the recycling is convenient;

[0036] The base 18 in the device is stuck in the ground by the ground nails 11, and the fixed structure is stable and will not move before the explosion, so the detonation distance can be accurately measured, thereby improving the accuracy of the test results;

[0037] The explosive is tied to the powder hopper 1, and the explosive is connected to the base 18, and can be indirectly fixed at a certain place through the base 18, so that it is not easy to be displaced or offset, and the base 18 is easy to fix and take out, and is easy to use;

[0038] The plastic support column 2 in the device and the medicine hopper 1 above the plastic support column 2 are disposable tools and can be made of low-strength and low-cost materials to save costs. The explosion-proof frame 5 has an explosion-proof effect and has a good protective effect on the device inside it, so that the device is not easily destroyed by sympathetic explosion and can be recycled, which reduces the corresponding use cost and is suitable for promotion.
