With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the utility model, a black and white grinding drill with strong stability is provided. Example 1

[0025] like Figure 1-Figure 4 As shown, the black and white grinding drill with strong stability according to the embodiment of the utility model includes a drill rod part 1 and a drill blade part 2, the drill rod part 1 and the drill blade part 2 are movably connected, a docking joint 8 is fixedly connected at the top center of the drill rod part 1, a heat insulation mechanism 9 is movably installed on the outside of the drill rod part 1, a dust suction mechanism 3 is sleeved on the outside of the heat insulation mechanism 9, the dust suction mechanism 3 includes a docking ring 4, a connecting rod 5 is fixedly connected to the surface of the docking ring 4, a negative pressure fan 6 is fixedly connected to the end of the connecting rod 5, a discharge pipe 7 is fixedly connected to the top of the negative pressure fan 6, and the number of negative pressure fans 6 and discharge pipes 7 is two groups, and they are symmetrically arranged.

[0026] In this embodiment, the insulation mechanism 9 includes a docking sleeve 901, the diameter of the docking sleeve 901 matches the drill rod part 1, and the outer wall of the docking sleeve 901 is bonded with insulation cotton 902. Through the setting of the insulation mechanism 9, people can directly take the drill bit after using it without the risk of burns.

[0027] In this embodiment, an anti-skid pad is bonded to the inner wall of the docking ring 4, and the anti-skid pad is made of rubber material. The anti-skid pad increases the friction between the docking ring 4 and the outside of the insulation mechanism 9, thereby making the docking of the two more stable.

[0028] In this embodiment, a threaded hole 13 is opened at the bottom center of the drill rod portion 1, and a threaded column 12 is fixedly connected to the top center of the drill blade portion 2. Through the provision of the threaded hole 13 and the threaded column 12, the drill rod portion 1 and the drill blade portion 2 can be movably disassembled, and the drill blade portion 2 can be quickly replaced after being damaged, thereby saving the consumption of the drill rod portion 1.

[0029] In this embodiment, the outer wall of the drill rod part 1 is coated with an anti-rust coating 10, and the material of the anti-rust coating 10 is zinc yellow anti-rust paint. Through the setting of the anti-rust coating 10, the drill rod part 1 has good environmental resistance during long-term use and is not easy to rust. Example 2

[0030] On the basis of the first embodiment, the preferred embodiment of the black and white grinding drill with strong stability provided by the utility model is as follows Figures 1 to 4 As shown:

[0031] In this embodiment, the surface of the drill blade 2 is coated with a thermal insulation coating 11, and the material of the thermal insulation coating 11 is nano-reflective thermal insulation paint. Through the setting of the thermal insulation coating 11, the drill blade 2 also has good thermal insulation performance and will not cause burns due to accidental touch.

[0032] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0033] In actual application, the docking sleeve 901 is inserted into the outer wall of the drill rod part 1 to complete the installation of the heat insulation mechanism 9, and then the docking ring 4 is sleeved on the outer wall of the docking sleeve 901 to complete the installation of the dust collection mechanism 3. The waste chips and impurities generated when the drill bit processes objects are sucked by two sets of negative pressure fans 6 and then discharged through the discharge pipe 7 at the top thereof, thereby avoiding people from inhaling harmful substances that affect their health. If the drill blade part 2 is worn after use, it can be rotated and removed, and a new drill blade part 2 can be inserted into the threaded hole 13 at the bottom of the drill rod part 1 through the threaded column 12 at the top thereof and rotated to complete quick replacement, thereby reducing the consumption of the drill rod part 1. Due to the setting of the heat insulation cotton 902 and the heat insulation coating 11, people can directly take the drill bit after use without being burned. The setting of the anti-rust coating 10 increases the environmental resistance of the drill rod part 1, thereby increasing its service life.

[0034] In summary, with the help of the above-mentioned technical scheme of the utility model, through the dust suction mechanism set up, impurities or dust and waste around the objects can be sucked up when the drill bit is in use, avoiding the impact of human inhalation on health. The setting of the heat insulation mechanism and the heat insulation coating allows people to directly pick up the drill bit after use, reducing the risk of accidental touch and burns, and the drill bit is divided into a drill rod and a drill blade, which can be flexibly disassembled and replaced, reducing resource consumption, thereby solving the problem that traditional black and white grinding drills do not have a dust suction function when used, which is inconvenient for people to pick up after use and causes waste of resources after the drill blade is damaged.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
