[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0022] Refer to Figure 1 - Figure 3 As shown in [the corresponding figure number], an embodiment provided by the present invention: A wall drilling device for building decoration includes a base 1. Four groups of movable wheels 2 are rotatably connected to the outer side wall of the base 1. A handle is provided at the rear end of the base 1. Through the handle, it is convenient to make the four groups of movable wheels 2 move synchronously, so as to move to the position where the building decoration needs to be drilled. A fixed seat 3 is fixedly connected to the center of the top end of the base 1. A connecting seat 4 is fixedly connected to the inner wall of the fixed seat 3. A telescopic rod 15 is hinged to the inner wall of the top end of the connecting seat 4. The top end of the telescopic rod 15 is fixedly connected to a connecting plate 5. Electric telescopic rods b16 are fixedly connected to both sides of the telescopic rod 15. The telescopic ends of the electric telescopic rods b16 are fixedly connected to the bottom end of the connecting plate 5. By the electric telescopic rods b16, the telescopic rod 15 can be driven to rise, so as to adjust the height of the connecting plate 5, and thus finely adjust the drilling position of the drill bit 14. A chute is provided on the surface of the connecting plate 5. The motor 8 is slidably connected to the inner wall of the chute of the connecting plate 5. By providing a chute on the connecting plate 5, the whole motor 8 can only move horizontally on the inner wall of the chute of the connecting plate 5. An electric telescopic rod a7 is fixedly connected to the rear side of the top end of the connecting plate 5. The telescopic end of the electric telescopic rod a7 is fixedly connected to the motor 8. The output shaft of the motor 8 is fixedly connected to the drill bit 14. By controlling the electric telescopic rod a7, the motor 8 can drive the drill bit 14 to move, so as to adjust the position of the building decoration drilling. At the same time, by driving the motor 8, the drill bit 14 can be rotated, so as to perform drilling operations on the building decoration position. And the drill bit 14 and the output end of the motor 8 are fixed by an external bolt, and can be adjusted and replaced according to the actual drilling position. A support rotating assembly 9 is provided on the outer side wall of the fixed seat 3.

[0023] Reference Figure 2 and Figure 3 , the support rotating assembly 9 includes a threaded rod 91. An internal thread groove is formed on the surface of the base 1. The threaded rod 91 penetrates and is threadedly connected to the inner wall of the base 1. A rotating block 92 is rotatably connected to the surface of the threaded rod 91. When the threaded rod 91 threadedly moves up and down on the inner wall of the base 1, it will drive the rotating block 92 to move up and down synchronously with it. Moreover, the rotating block 92 can only rotate circumferentially on the surface of the threaded rod 91. The bottom end of the rotating block 92 is rotatably connected to a contact plate 93. A guide post 98 is fixedly connected to the left outer wall of the contact plate 93. When the threaded rod 91 threadedly moves downward on the inner wall of the base 1, it will drive the contact plate 93 to descend synchronously, so that the rubber anti-slip layer at the bottom end of the contact plate 93 can contact the ground, thereby increasing stability. And by arranging a guide post 98 on the left side of the contact plate 93, the moving position of the contact plate 93 can be guided.

[0024] Reference Figure 2 and Figure 3, a guide block 96 is fixedly connected to the outer side wall of the fixed seat 3. An internal thread groove is formed inside the guide block 96. A positioning screw rod b97 is threadedly connected to the inner wall of the guide block 96. An L-shaped rack 95 is slidably connected to the inner side wall of the guide block 96. The function of the guide block 96 is to guide the moving position of the L-shaped rack 95. And the positioning screw rod b97 moves outward in the inner wall of the guide block 96 through threading, so as to disengage from the internal thread groove of the L-shaped rack 95, and the L-shaped rack 95 is connected to the rotating block 92 through the positioning bolt a94. When the rotating block 92 descends following the threaded rod 91, it will drive the L-shaped rack 95 to descend synchronously. An internal thread groove is formed on the outer side wall of the L-shaped rack 95. The end of the positioning screw rod b97 is threadedly connected to the outer side wall of the L-shaped rack 95. An internal thread groove is formed at the bottom end of the L-shaped rack 95. A positioning bolt a94 is threadedly connected to the inner wall of the bottom end of the L-shaped rack 95. A gear 99 is meshed with the side wall at the top end of the L-shaped rack 95. When the L-shaped rack 95 descends, it will mesh with the gear 99, so that the gear 99 can drive the telescopic rod 15 to rotate around its hinge point, so that the angle of the drilling position can be changed, and drilling can be carried out above the building construction. The gear 99 is rotatably connected to the side wall at the top end of the connecting seat 4, and the rotating center axis of the gear 99 is fixedly connected to the telescopic rod 15. The guide post 98 penetrates and is slidably connected to the left surface of the base 1. The contact plate 93 is slidably connected to the inner wall of the bottom end of the base 1. An internal thread groove is formed on the outer side wall of the rotating block 92. The end of the positioning bolt a94 is threadedly connected to the side wall of the rotating block 92. By passing the positioning bolt a94 through the L-shaped rack 95 and threadedly connecting it to the rotating block 92, when the threaded rod 91 rotates, it will drive the contact plate 93 to contact the ground, thereby increasing the stability. At the same time, it will also make the L-shaped rack 95 mesh with the gear 99 to make the gear 99 rotate, thereby driving the angles of the telescopic rod 15 and the connecting plate 5 to also flip.

[0025] Refer to Figure 2 and Figure 4, a dust suction box 10 is fixedly connected to the top of the connecting plate 5. A discharge door is provided on the surface of the dust suction box 10, so that the dust drilled by the drill bit 14 can be sucked into the interior of the dust suction box 10 from the connecting frame 11 through the dust suction hood 12, and the internal dust can be processed by opening the discharge door. At the same time, a fan is provided at the rear end of the dust suction box 10, and a filter screen is provided at the connection between the fan and the dust suction box 10, so as to isolate the dust. A connecting frame 11 is fixedly connected to the surface of the dust suction box 10. One end of the connecting frame 11 away from the dust suction box 10 is fixedly connected to a dust suction hood 12. A support 13 is fixedly connected to the rear end of the dust suction hood 12. One end of the support 13 away from the dust suction hood 12 is fixedly connected to the surface of the connecting plate 5. A cavity is provided at the center of the dust suction hood 12. The drill bit 14 penetrates and is slidably connected to the interior of the cavity of the dust suction hood 12. By the drill bit 14 penetrating the cavity of the dust suction hood 12, the dust suction hood 12 contacts the drilling position of the building construction during drilling. At the same time, as the drill bit 14 continuously passes through the dust suction hood 12 to adjust the depth, the dust will be sucked into the interior of the connecting frame 11 from the slot holes on the inner side of the dust suction hood 12.

[0026] Working principle: Four sets of moving wheels 2 are rotatably connected to the outer side wall of the base 1, and a handle is provided at the rear end. The operator pushes the handle to drive the four sets of moving wheels 2 to rotate synchronously, so that the device can be conveniently moved to the position where drilling is required for building decoration, realizing flexible position adjustment. After reaching the drilling position, the device is further fixed and angle-adjusted through the subsequent support and rotation assembly 9 to ensure the stability and accuracy of the drilling operation.

[0027] Rotate the threaded rod 91, and the threaded rod 91 moves up and down in the inner wall thread of the base 1, driving the rotating block 92 and the contact plate 93 to rise and fall synchronously. When the contact plate 93 descends, the rubber anti-slip layer at its bottom end contacts the ground, increasing the friction between the device and the ground and enhancing the stability of the device during drilling; the guide post 98 guides the movement of the contact plate 93 to ensure its stable rise and fall.

[0028] At the same time, when it is necessary to adjust the angle of the angle drill bit 14 and the stability of the contact plate 93 at the same time, first, unscrew the positioning screw b97 so that it disengages from the internal thread groove of the L-shaped rack 95, and then connect the L-shaped rack 95 to the rotating block 92 through the positioning bolt a94. When the threaded rod 91 drives the rotating block 92 to descend, the rotating block 92 will drive the L-shaped rack 95 to descend synchronously. During the descent of the L-shaped rack 95, it meshes with the gear 99, driving the gear 99 to rotate, and then driving the telescopic rod 15 and the connecting plate 5 to rotate around their hinge points, realizing the change of the angle of the drilling position. In this way, the device can perform drilling operations on different angle positions such as above the building construction. At the same time, the telescopic rod 15 is driven to rise and fall by the electric telescopic rod b16, so as to finely adjust the position of the drill bit 14.

[0029] During the drilling process, the drill bit 14 penetrates through the cavity of the dust suction hood 12 and contacts the drilling area of the building construction. As the drill bit 14 penetrates deeper, the generated dust is sucked into the inside of the connecting frame 11 through the slot holes on the inner side of the dust suction hood 12, and then enters the dust suction box 10. The fan operates to generate suction, sucking the dust into the dust suction box 10. The filter screen isolates the dust to prevent it from entering the inside of the fan. When a certain amount of dust is collected in the dust suction box 10, the discharge door on the surface of the dust suction box 10 is opened to clean and dispose of the internal dust.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
