[0002] In the field of structural decoration, with the continuous emergence of new wallboard materials and components, such as lightweight composite wallboards, fiber cement boards, etc., these new wallboards have many characteristic advantages in terms of structural decoration performance, and these board surfaces also have higher requirements for hole-opening operations. Traditional hole-opening devices, such as ordinary electric drills, need to lay out and position on the wall surface when opening holes. Along with drilling, dust and noise will be generated in the air, and the drilling direction of the drill bit is also prone to deviation to varying degrees. When opening non-circular holes (such as plum blossom-shaped holes), multiple drillings and secondary repairs are often required. Therefore, in order to reduce dust pollution and noise pollution and achieve one-time forming of decorative holes with special shapes on the wall surface, it is necessary to design a drilling device to solve the above technical problems.

By optimizing the structure of the connection position of the drill bit of the hand-held drill, a structure is provided on the electric drill body with a laser induction device at the top, in which a combined drill bit is driven to rotate and drill by an internal motor through a transmission component. While the laser induction device measures the hole position, the combined drill bit is used for synchronous drilling to complete one-time forming of a plum blossom-shaped decorative hole. And by providing a dust collection and noise reduction device on the electric drill body, the effects of reducing dust pollution and noise pollution are achieved. The structure is simple, the positioning is accurate, the edge is neat, the pollution is reduced, the forming effect is good, the quality is high, and no secondary repair is required.

[0024] The drilling device for one-time forming of decorative holes, such as Figures 1-5 shown, includes a drill body 1. An integrated drill bit is provided outside the left end face of the drill body 1, and the integrated drill bit is connected to a motor inside the drill body 1 through a transmission assembly, and the motor drives the integrated drill bit to rotate through the transmission assembly. A dust collection and noise reduction device is provided at the left end of the drill body 1 to cover the integrated drill bit inside it and always fit against the wall during the drilling process of the integrated drill bit for dust collection. The exposed length of the integrated drill bit is adjusted by adjusting the length of the dust collection and noise reduction device. A laser induction device 4 for measuring and displaying the vertical and horizontal coordinate data of the aiming point on the wall is installed on the top of the drill body 1. Specifically, the laser induction device 4 is a laser infrared rangefinder, and under the action of the laser infrared rangefinder, the measurement and display of the longitudinal and horizontal coordinate data of the aiming point on the wall are realized for positioning the opening position. In the above structure, by optimizing the structure of the connection position of the hand-held drill bit, a structure is provided on the drill body 1 in which the integrated drill bit is driven to rotate and drill by the internal motor through the transmission assembly, and the synchronous drilling of the integrated drill bit is utilized to complete the one-time forming of the plum blossom-shaped decorative holes, solving the drawbacks of the traditional hand-held drill that requires multiple drillings and multiple repairings for forming.

[0025] such as Figure 2 、 3As shown in the figure, the specific structure of the transmission assembly is as follows: The transmission assembly includes a driving gear 10 and a plurality of driven gears 12 that are circumferentially distributed on the outer periphery of the driving gear 10 and mesh with the driving gear 10. On the left end faces of the driving gear 10 and the driven gears 12, there are gear rods 15 with long keys on their outer walls, and on the right end faces of the driven gears 12, there are fixed rods 16 with a polygonal cross-section in the center, as Figure 5 shown, the rotating shaft 9 with a long key on the motor in the electric drill body 1 is adaptively connected to the central shaft hole with a keyway hole on the right end face of the driving gear 10. The fixed rods 16 at the right ends of the plurality of driven gears 12 are respectively adaptively inserted into the hexagon bearings 6 that are circumferentially distributed on the outer periphery of the rotating shaft 9 and rotatably installed on the left end face of the electric drill body 1. The transmission assembly is adaptively connected to the gear rods 15 on the left end faces of the driving gear 10 and the plurality of driven gears 12, and under the drive of the motor in the electric drill body 1, the combined drill bit rotates for drilling.

[0026] As Figure 2 , 3 shown, the specific structure of the combined drill bit is as follows: The combined drill bit includes a middle drill bit 11 and edge drill bits 13 that are circumferentially distributed on the outer periphery of the middle drill bit 11. The slot 17 with a keyway on the right end face of the middle drill bit 11 is adaptively connected to the gear rod 15 at the left end of the driving gear 10, and the slot 17 with a keyway on the right end face of the edge drill bit 13 is adaptively connected to the gear rod 15 at the left end of the driven gear 12; specifically, there is a gap between the middle drill bit 11 and the plurality of edge drill bits 13. The setting of this gap can not only avoid interference between the drill bits, but also enable the crushed slag that enters between the drill bits to be crushed again in the gap and discharged outward. When the combined drill bit needs to rotate, the rotating shaft 9 drives the driving gear 10 to rotate, the driving gear 10 drives the five surrounding driven gears 12 to rotate, the driving gear 10 drives the middle drill bit 11 to rotate, and the driven gears 12 drive the edge drill bits 13 to rotate, realizing simultaneous drilling of the middle drill bit 11 and the five edge drill bits 13.

[0027] As Figure 4As shown in the figure, the specific structure of the dust collection and noise reduction device is as follows: The dust collection and noise reduction device includes a hollow dust collection sleeve 7 with openings at both left and right ends, and a sound insulation and noise reduction pad 8 fixed on the outer circumferential wall of the dust collection sleeve 7. A guiding ring plate 19 is fixed on the inner wall of the dust collection sleeve 7 at the position of the right port, and a guiding baffle 20 is located on the left side of the guiding ring plate 19. Two symmetrically arranged chutes 18 are made on the surfaces of the guiding ring plate 19 and the guiding baffle 20, which are distributed vertically. A fixing sleeve 14 is fixed at the left end of the electric drill body 1, and two symmetrically arranged guide rails 5 are provided on the outer wall of the fixing sleeve 14, which are distributed vertically. The dust collection sleeve 7 is sleeved on the fixing sleeve 14, and the combined drill bit passes through the guiding ring plate 19 and a plurality of through holes provided on the guiding baffle 20. The chutes 18 on the guiding ring plate 19 and the guiding baffle 20 are adapted to the guide rails 5 at the corresponding positions on the fixing sleeve 14, and dust collection and noise reduction protection are carried out when the dust collection sleeve 7 abuts against the wall and moves to the right until the combined drill bit contacts and drills into the wall drilling position. Among them, a plurality of through holes corresponding to the positions of the middle drill bit 11 and the edge drill bit 13 are made on the surface of the guiding baffle 20. When the middle drill bit 11 and the edge drill bit 13 pass through the corresponding through holes for drilling, the guiding baffle 20 plays a role in blocking miscellaneous dust, so that the miscellaneous dust is concentrated and collected in the dust collection sleeve 7 and is located on the left side of the guiding baffle 20. In the above structure, by setting a dust collection and noise reduction device on the electric drill body 1, the wall drilling position and the combined drill bit are covered in the dust collection sleeve 7, achieving the effect of reducing dust pollution, and by setting a sound insulation and noise reduction pad on the outer wall of the dust collection sleeve 7, achieving the effect of reducing noise pollution;

[0028] In the above structure, when the left end head of the combined drill bit is located at the drilling position, the left end of the dust collection sleeve 7 abuts against the wall surface. As the drilling depth increases, the dust collection sleeve 7 slides to the right along the length direction of the guide rail 5. During this process, the left end of the dust collection sleeve 7 always fits and contacts with the wall surface, and the crushed slag and dust drilled are collected in the dust collection sleeve 7 until the drilling depth reaches the required value and then stops. The dust collection sleeve 7 is removed from the fixing sleeve 14, and the impurities and dust collected in the dust collection sleeve 7 are poured out.

[0029] The electric drill body 1 is of a handheld structure. A rubber vibration isolation pad 2 is sleeved on the handle at the bottom of the electric drill body 1, which is used to reduce the vibration of the hand during mechanical operation to prevent slipping and improve the safety and reliability of use. A balance grip 3 is provided at the rear end of the electric drill body 1, which cooperates with the bottom handle to provide a double-holding function.

[0030] The technical solution has a simple structure, accurate positioning, neat edges, reduced pollution, good forming effect, high quality, no need for secondary repair, high drilling efficiency, and is convenient for popularization and application.
