DETAILED DESCRIPTION

[0022] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] Please refer to Figure 1-5 A circular hole drilling device for a wall during construction comprises a first support frame 1 and a second support frame 2, wherein a fixed rack 6 and an L-shaped support 4 are arranged between the first support frame 1 and the second support frame 2, wherein one end of the fixed rack 6 is fixedly connected to the first support frame 1, and the other end passes through the L-shaped support 4 and is fixedly connected to the second support frame 2, wherein a motor 5 is arranged on the L-shaped support 4, and an output shaft of the motor 5 passes through the L-shaped support 4 and is detachably connected to an drilling tube 8, wherein the L-shaped support 4 moves along the fixed rack 6 to drill a circular hole; under normal conditions, the drilling tube 8 does not contact the wall, and when drilling a circular hole, the L-shaped support 4 moves toward the wall, and after the motor 5 is started, the drilling tube 8 rotates, thereby drilling a circular hole in the wall; since the drilling tube 8 and the motor are detachable, the concrete block remaining in the drilling tube 8 after drilling is completed is also convenient to take out, and the use is simple.

[0024] In the utility model, a slot 41 is provided inside the L-shaped support 4 along its length direction, and the fixed rack 6 passes through the L-shaped support 4 in the slot 41. A gear 42 matching the fixed rack 6 is provided in the slot 41, and the rotating axis of the gear 42 extends outward and is fixedly connected to the handle 43; further, two optical axes 7 are provided between the first support frame 1 and the second support frame 2, and the two optical axes 7 pass through the L-shaped support 4 and are symmetrically arranged on both sides of the fixed rack 6.

[0025] Therefore, during the process of drilling a circular hole, the whole is placed on the ground without manual holding. First, the motor is started to drive the drilling tube 8 to rotate, and then the handle 43 is manually turned. At this time, the gear 42 cooperates with the fixed rack 6 to make the whole move horizontally along the optical axis 7. As the whole (L-shaped support and motor) moves, the drilling tube 8 gradually contacts the wall, thereby realizing the drilling of a circular hole in the wall. The speed and progress of drilling are adjusted by turning the handle. For details, please refer to Figure 6 ; After the excavation is completed, turn the handle in the opposite direction to retract the whole body, pull the excavation tube out of the wall, and the operation is completed; because the L-shaped support and the motor move horizontally along the optical axis, the excavated circular hole is also a straight hole, ensuring the excavation accuracy of the circular hole and avoiding tilting.

[0026] Furthermore, the output shaft of the motor 5 is a gear shaft 51, one end of the excavating tube 8 is provided with an excavating cutter head 83, and the other end is provided with a connecting tube 81 that cooperates with the gear shaft 51. The excavating tube 8 is plugged and unpluggedly connected to the gear shaft 51 through the connecting tube 81, which can increase the transmission efficiency of the motor. The gear shaft 51 and the connecting tube 81 are connected through a locking bolt 82, which is also convenient for disassembling the excavating tube and facilitating the removal of the excavated concrete blocks.

[0027] As a preferred embodiment, the chiseling tool head 83 is triangular in shape and is provided with a middle blade 831 and two side blades 832. The middle blade 831 is arranged between the two side blades 832. The three blades rotate with the chiseling tube 8 to chisel a circular hole in the wall, thereby improving the chiseling efficiency.

[0028] Based on the above embodiment, an extension frame 3 is provided above the second support frame 2, and a reference hole 31 corresponding to the excavation tube 8 is provided on the extension frame 3. After the L-shaped support 4 moves, the excavation tube 8 extends into the wall in the reference hole 31 for excavation. In addition, a dust cover 32 is provided on the outer side of the extension frame 3, and a connected dust suction pipe 33 is provided below the dust cover 32. The dust suction pipe 33 passes through the second support frame 2 and is connected to a dust collector 34. The dust collector 34 is fixed on the inner side of the second support frame 2. When in use, the port of the dust cover 32 is in contact with the wall surface. A large amount of mud and smoke will be generated during the excavation process, and these mud and smoke will eventually be blocked by the dust cover 32 to prevent them from diffusing into the external air. The mud and smoke blocked by the dust cover 32 are sucked into the dust collector 34 through the dust suction pipe 33 to prevent the mud and smoke from floating and affecting the air quality. In this embodiment, the dust collector 34 is an existing ordinary vacuum cleaner, which can play a dust suction role and will not be described in detail here.

[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
