[0005] Preferably, a handle is fixedly connected to one end of the drilling body away from the drill bit.

[0006] Preferably, the two sliding rods are both clamped in the sliding groove.

[0007] Preferably, threads are provided on the edges of the outer walls of the mounting tube and the support ring.

[0008] Preferably, the distribution range of the loose parts at the upper end is smaller than the distribution range of the loose parts at the lower end.

[0009] The beneficial effects of the present invention are: first, the dense part and the loose part arranged at different positions can play different roles, the dense part can play a dust-proof effect, the loose part at the upper end can be used to observe the drilling situation of the drill bit, and the loose part with a larger range arranged at the lower end can carry some gravel to prevent the gravel from splashing, thereby improving the practicality of the dust-proof mesh, and through the arrangement of the first mounting threaded ring, the second mounting threaded ring, the support tube, and the support ring, the dust-proof mesh can be disassembled and maintained, thereby improving the service life of the dust-proof mesh.

[0016] Reference Figure 1-5The blasting drilling structure includes a drilling body 1 and a mounting tube 2. Slide grooves 101 are provided on both sides of the outer wall of the drilling body 1, and slide rods 21 are fixedly connected to both sides of the inner wall of the mounting tube 2, and the two slide rods 21 are slidably connected to the slide grooves 101. The outer wall of the mounting tube 2 is fixedly connected to several support rods 22 arranged in an L shape, and several support rods 22 are fixedly connected to a support ring 23 near one end of the drill bit. The inner wall of the support ring 23 is threaded with several threaded rods 3, and the outer ends of the rod walls of one side of the several threaded rods 3 are sleeved with gaskets 31. The outer wall edge of the mounting tube 2 is threaded with a first mounting threaded ring 41, and the outer wall edge of the support ring 23 is threaded with a second mounting threaded ring 42. A dust-proof gauze 4 is fixedly connected between the second mounting threaded ring 42 and the first mounting threaded ring 41. Loose parts 43 are provided at the upper and lower ends of the dust-proof gauze 4, and a dense part 44 is provided between the two loose parts 43. Furthermore, a handle 11 is fixedly connected to the end of the drilling body 1 away from the drill bit, and the handle 11 is held by hand to push the drilling body 1 to move. Furthermore, the two slide bars 21 are both stuck in the slide groove 101, and the mounting tube 2 slides along the slide groove 101 through the slide bars 21. Furthermore, threads are provided on the edges of the outer walls of the mounting tube 2 and the support ring 23, which facilitates the first mounting threaded ring 41 and the second mounting threaded ring 42 to be threadedly connected to the mounting tube 2 and the support ring 23 respectively. Furthermore, the distribution range of the loose portion 43 at the upper end is smaller than that of the loose portion 43 at the lower end. The dust-proof mesh 4 of the loose portion 43 at the upper end can be used to observe the drilling situation of the drill bit, the dense portions 44 provided at both ends can play a dust-proof role, and the loose portion 43 with a larger range provided at the lower end can carry some gravel.

[0017] When using this device, first place the support ring 23 in the area to be drilled, and then rotate several threaded rods 3 to fix the support ring 23, and then synchronously rotate the first mounting threaded ring 41 and the second mounting threaded ring 42 to the mounting tube 2 and the outer wall of the support ring 23, and then start the drilling body 1, and slowly push the drilling body 1 toward the side of the drill bit with the handheld handle 11. The dust-proof mesh 4 provided can block dust to avoid dust pollution of the environment, and at the same time can carry some gravel to prevent gravel from splashing, and by providing the mounting tube 2 and the first mounting threaded ring 41 and the support ring 23 and the second mounting threaded ring 42 with threaded connection, the dust-proof mesh 4 can be conveniently disassembled and maintained, thereby improving the service life of the dust-proof mesh 4.
