DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 In this embodiment, an electric drill tool head that is easy to position includes a drill rod 1, a drill bit 2 is provided on the lower surface of the drill rod 1, and positioning mechanisms 3 for facilitating the positioning of the drill bit 2 are provided on the left and right ends of the outer surface of the drill bit 2, and a dust suction mechanism 4 for dust suction is provided on the top of the inner cavity of the drill rod 1.

[0023] Among them, a telescopic rod is fixed to the inner top wall of the drill rod 1, and a spring is sleeved on the outer surface of the telescopic rod. The lower surface of the telescopic rod is fixed to the upper surface of the drill bit 2, and the two ends of the spring are respectively fixedly connected to the opposite sides of the drill rod 1 and the drill bit 2. Slide bars are fixed to the opposite sides of the left and right side walls of the inner cavity of the drill rod 1, and sliders are fixed to the left and right sides of the top of the drill bit 2, and the sliders make linear movements up and down in the inner cavity of the slide bar.

[0024] See also Figure 3In order to assist the drill bit 2 in rapid positioning, the positioning mechanism 3 in this embodiment includes a fixed box 301 fixed to the left and right ends of the outer surface of the drill bit 2, and the top between the opposite sides of the left and right side walls of the inner cavity of the fixed box 301 is rotatably connected with a bidirectional screw 302 through a bearing, and the left and right ends of the outer surface of the bidirectional screw 302 are both threadedly connected with a threaded sleeve 303, so that the two bidirectional screws 302 rotate, and the rotation of the bidirectional screw 302 causes the two threaded sleeves 303 threadedly connected on its surface to make relative movement, and the inner cavity of the fixed box 301 is provided with a moving plate 304, and the left and right ends of the upper surface of the moving plate 304 and the lower surface of the threaded sleeve 303 are fixed with hinge seats 305, and the upper and lower sides of the hinge seats 305 are provided between the opposite sides. The movement of the hinged rod 306 and the two threaded sleeves 303 drives the two upper hinged seats 305 to move, thereby driving the two lower hinged seats 305 to move through the hinged rod 306. The movement of the two lower hinged seats 305 causes the movable plate 304 to move downward. A suction cup 307 is fixed to the lower surface of the movable plate 304. The lower surface of the suction cup 307 penetrates the fixed box 301 and extends to the lower side of the fixed box 301. The movement of the movable plate 304 drives the suction cup 307 to move downward and makes the suction cup 307 adsorbed on the surface of the object until the drill bit 2 is compressed. Then the electric drill is started. When the drill bit 2 drills a hole in the object, it will move downward. At this time, the drill bit 2 will extend and drive the telescopic rod and the spring to extend, thereby facilitating the positioning of the drill bit 2.

[0025] Among them, the opposite sides of the two bidirectional screws 302 penetrate the fixed box 301 and extend to the outside of the fixed box 301 and are fixed with a handwheel, and the two threaded sleeves 303 are symmetrically distributed on the left and right ends of the vertical central axis, and the left and right ends between the opposite sides of the inner top wall and the inner bottom wall of the fixed box 301 are fixed with limit rods, and the left and right ends of the upper surface of the movable plate 304 are provided with through holes that are compatible with the outer diameter of the limit rod, and the through holes make up and down linear motion on the outer surface of the limit rod. When the movable plate 304 moves, the through holes on the left and right ends of its upper surface slide downward on the outer surface of the limit rod, thereby limiting the movement of the movable plate 304.

[0026] See also Figure 4 In order to prevent the staff from inhaling a large amount of dust when drilling, the dust collection mechanism 4 in this embodiment includes a mounting groove 401 opened at the top of its inner cavity, a mounting box 402 is fixed on the right side of the mounting groove 401, and a fan 403 is fixed in the inner cavity of the mounting box 402. The left and right ends of the bottom of the inner cavity of the mounting groove 401 are connected with air ducts 404. When the fan 403 is started, the air inlet end of the fan 403 generates suction in the inner cavity of the mounting groove 401, and the dust generated during drilling is sucked in through the two air ducts 404. The other end of the air duct 404 is the drill rod 1 and extends to the lower side of the drill rod 1. The dust entering the inner cavity of the air duct 404 can enter the inner cavity of the mounting groove 401 through the guidance of the air duct 404. After the staff drills the hole, the sealed door can be opened to clean the dust.

[0027] Among them, the air inlet end of the fan 403 passes through the drill rod 1 and extends to the inner cavity of the installation groove 401, and a filter is fixed in its inner cavity, which can prevent dust from entering the inner cavity of the fan 403 and causing damage to the fan 403. A screen is fixed at the bottom of the inner cavity of the air duct 404. The screen arranged at the bottom of the inner cavity of the air duct 404 can prevent large particles from entering the inner cavity of the air duct 404, thereby preventing the air duct 404 from being blocked.

[0028] It should be noted that a sealing door is hinged on the outer surface of the drill rod 1 and located on the front side of the installation groove 401 through a door hinge, which can facilitate the staff to clean the dust collected in the inner cavity of the installation groove 401. The size of the sealing door is larger than the size of the inner cavity of the installation groove 401.

[0029] The working principle of the above embodiment is:

[0030] (1) When drilling a hole in an object using an electric drill, first fix the drill rod 1 to the electric drill, then align the drill bit 2 with the drilling point, turn the hand wheel to rotate the two bidirectional screw rods 302, and the rotation of the bidirectional screw rods 302 causes the two threaded sleeves 303 threadedly connected to the surface thereof to move relative to each other. The movement of the two threaded sleeves 303 drives the two upper hinge seats 305 to move, thereby driving the two lower hinge seats 305 to move through the hinge rod 306. The movement of the two lower hinge seats 305 causes the movable plate 306 to move relative to the movable plate 306. 04 moves downward, and when the movable plate 304 moves, the through holes on the left and right ends of its upper surface slide downward on the outer surface of the limiting rod, thereby limiting the movement of the movable plate 304. The movement of the movable plate 304 drives the suction cup 307 to move downward, and makes the suction cup 307 adsorbed on the surface of the object until the drill bit 2 is compressed, and then the electric drill is started. When the drill bit 2 drills a hole in the object, it will move downward. At this time, the drill bit 2 will extend, and drive the telescopic rod and the spring to extend, so that the drill bit 2 can be positioned easily.

[0031] (2) When drilling with the drill bit 2, dust may be generated. In order to prevent the staff from inhaling a large amount of dust, the fan 403 is first started. The air inlet end of the fan 403 generates suction in the inner cavity of the installation groove 401, and the dust generated by drilling is sucked in through the two air ducts 404. The screen provided at the bottom of the inner cavity of the air duct 404 can prevent large particles from entering the inner cavity of the air duct 404. The dust entering the inner cavity of the air duct 404 can enter the inner cavity of the installation groove 401 through the guidance of the air duct 404. After the staff drills the hole, the sealed door can be opened to clean the dust.
