[0022] The driving mechanism includes a support plate 10, which is rotatably connected to the cross plate 3. A slide groove 11 is provided inside the support plate 10, and a slider 12 is slidably inserted inside the slide groove 11. There are two groups of sliders 12, and the two groups of sliders 12 are fixedly connected to the No. 1 rotating member 4 and the No. 2 rotating member 5 respectively. A sliding component is arranged outside the slider 12.

[0023] The sliding assembly includes a rotatable turntable 13, which is rotatably installed below the cross plate 3. A guide rail 15 is arranged inside the turntable 13, and the guide rail 15 is inclined.

[0024] A motor 6 is fixedly installed above the transverse plate 3 , a rotating shaft 14 is fixedly installed at the output end of the motor 6 , and the rotating shaft 14 is fixedly connected to the rotating disk 13 .

[0025] Specifically, with the cooperation of the base 1, the vertical plate 2 and the horizontal plate 3, the motor 6 is connected to the external power supply, and the motor 6 drives the turntable 13 to rotate, thereby driving the guide rail 15 to rotate synchronously.

The guide rail 15 can drive the guide block 16 to move synchronously when it moves, and the guide block 16 drives the slider 12 to move inside the slide groove 11. The slider 12 drives the No. 1 rotating part 4 and the No. 2 rotating part 5 to move synchronously. When the motor 6 rotates, it can drive the No. 1 rotating part 4 and the No. 2 rotating part 5 to contact each other. At this time, the No. 1 drill rod 7 is between the No. 1 rotating part 4 and the No. 2 rotating part 5. The No. 1 rotating part 4 and the No. 2 rotating part 5 can drive the No. 1 drill rod 7 to rotate, thereby driving the drill bit 8 to rotate. Since the No. 1 drill rod 7 is threadedly connected to the base 1, the No. 1 drill rod 7 can drive the drill bit 8 to move downward when it rotates.

[0026] When the No. 1 drill rod 7 moves to the bottom of the No. 1 rotating member 4, the motor 6 is rotated in the opposite direction, and the turntable 13 can drive the slider 12 to move through the guide block 16. At this time, the No. 1 rotating member 4 and the No. 2 rotating member 5 are away from each other, and the No. 2 drill rod 9 is located between the two groups of clamps 28. The moving mechanism drives the two groups of clamps 28 and the No. 2 drill rod 9 to move toward the direction of the No. 1 rotating member 4, and pushes the No. 2 drill rod 9 between the No. 1 rotating member 4 and the No. 2 rotating member 5. The motor 6 rotates forward again, and the No. 1 rotating member 4 and the No. 2 rotating member 5 approach each other to clamp the No. 2 drill rod 9 and drive the No. 2 drill rod 9 to rotate.

[0027] The moving mechanism includes a mounting plate 26 and a movable groove 27. The movable groove 27 is opened inside the base 1 and the cross plate 3. The mounting plate 26 is slidably installed inside the movable groove 27. The mounting plate 26 and the two groups of splints 28 are slidably connected. A connecting plate 33 is provided on the side of the splint 28 away from the No. 1 rotating member 4. The connecting plate 33 is connected to the rotating shaft 14 through a power structure, and the connecting plate 33 is connected to the two groups of splints 28 through an adjusting component.

[0028] The power structure includes a gear 24 and a rack 25 . The gear 24 is fixedly sleeved on the outside of the rotating shaft 14 . The rack 25 is slidably installed above the cross plate 3 . The rack 25 is meshed with the gear 24 . The rack 25 is fixedly connected to the connecting plate 33 .

[0029] The adjusting assembly includes an adjusting member 31, which is arranged between the connecting plate 33 and the clamping plate 28. The adjusting member 31 and the mounting plate 26 are slidably installed. The adjusting member 31 is connected to the connecting plate 33 through an elastic structure. Push plates 32 are rotatably installed at both ends of the adjusting member 31. A support block 30 is rotatably installed at one end of the push plate 32 away from the adjusting member 31. The support block 30 and the clamping plate 28 are fixedly connected, and a magnet 29 is fixedly installed between the two sets of clamping plates 28.

[0030] The elastic structure includes a rod 35 and a spring 36. The rod 35 slides through the adjusting member 31. The rod 35 and the connecting plate 33 are fixedly connected. The spring 36 is movably sleeved on the outside of the rod 35. The spring 36 is located inside the adjusting member 31 and the connecting plate 33. A push member 34 is fixedly installed on one end of the rod 35 away from the connecting plate 33. The push member 34 is located between the clamping plate 28 and the adjusting member 31.

[0031] Specifically, when the rotating shaft 14 rotates, it drives the gear 24 to rotate synchronously. When the gear 24 rotates forward, the gear 24 does not contact the rack 25, and the rack 25 does not move. When the gear 24 rotates reversely, the gear 24 and the rack 25 contact, and the rack 25 moves in the direction of the rotating shaft 14 on the upper side of the cross plate 3. The rack 25 drives the connecting plate 33 to move synchronously. When the connecting plate 33 moves, it drives the two sets of clamping plates 28 and the mounting plate 26 to move synchronously, and the mounting plate 26 slides inside the movable groove 27.

[0032] When the mounting plate 26 stops moving, the connecting plate 33 continues to move, and the connecting plate 33 drives the adjusting member 31 to move through the spring 36, and the adjusting member 31 drives the push plate 32 to rotate, and the push plate 32 drives the two groups of clamping plates 28 to move away from each other through the connecting plate 33. It should be noted that magnets 29 are fixedly installed between the two groups of clamping plates 28, and the two groups of magnets 29 attract each other. When the two groups of clamping plates 28 move to the moving position, they stop moving, and the connecting plate 33 continues to move. The connecting plate 33 drives the adjusting member 31 to move synchronously through the rod 35, and the adjusting member 31 pushes the No. 2 drill rod 9 between the No. 1 rotating member 4 and the No. 2 rotating member 5. At this time, the spring 36 is deformed by the force, and the elastic force of the spring 36 is greater than the suction force between the two groups of magnets 29.

[0033] The sliding structure includes a protrusion 17 and a groove 18. The protrusion 17 is fixedly installed on the adjacent side of the No. 1 rotating member 4 and the No. 2 rotating member 5. The groove 18 is opened outside the No. 1 drill rod 7 and the No. 2 drill rod 9. The protrusion 17 and the groove 18 are slidably connected.

[0034] When the No. 1 rotating member 4 and the No. 2 rotating member 5 clamp the No. 1 drill rod 7 , the protrusion 17 is located inside the groove 18 , so that when the No. 1 drill rod 7 moves downward, the protrusion 17 slides inside the groove 18 .

[0035] An installation groove 19 and a limit groove 22 are provided above the No. 1 rotating member 4, and a installation block 20 is fixedly installed below the No. 2 rotating member 5. The installation block 20 and the installation groove 19 are plug-fitted together, and a limit block 21 is fixedly installed below the installation block 20. The limit block 21 and the limit groove 22 are slidably connected, and a fixed block 23 is fixedly installed inside the installation groove 19.

[0036] Specifically, when drill rod No. 2 9 is located between rotating member No. 1 4 and rotating member No. 2 5, the limiting block 21 passes through the limiting groove 22 and falls into the interior of the mounting groove 19. At this time, the mounting block 20 is inserted into the interior of the mounting groove 19. Rotating member No. 1 4 and rotating member No. 2 5 drive drill rod No. 2 9 to rotate synchronously. When drill rod No. 2 9 drives the mounting block 20 and the limiting block 21 to rotate, drill rod No. 1 7 and drill rod No. 2 9 can be connected together. Under the action of the fixing block 23, drill rod No. 2 9 drives drill rod No. 1 7 to rotate synchronously.

[0037] Working principle: With the cooperation of the base 1, the vertical plate 2 and the horizontal plate 3, the motor 6 is connected to the external power supply, and the motor 6 drives the turntable 13 to rotate, thereby driving the guide rail 15 to rotate synchronously. It should be noted that magnetic blocks are fixedly installed on the edge of the support plate 10 and the bottom of the horizontal plate 3, and the two groups of magnetic blocks attract each other. When the guide rail 15 moves, it can drive the guide block 16 to move synchronously. The guide block 16 drives the slider 12 to move inside the slide groove 11. The slider 12 drives the No. 1 rotating member 4 and the No. 2 rotating member 5 to move synchronously. When the motor 6 rotates, it can drive the No. 1 rotating member The movable member 4 and the No. 2 rotating member 5 are in contact with each other. At this time, the No. 1 drill rod 7 is between the No. 1 rotating member 4 and the No. 2 rotating member 5. The No. 1 drill rod 7 can be driven to rotate by the No. 1 rotating member 4 and the No. 2 rotating member 5, thereby driving the drill bit 8 to rotate. Since the No. 1 drill rod 7 is threadedly connected to the base 1, the No. 1 drill rod 7 can drive the drill bit 8 to move downward when rotating. When the No. 1 rotating member 4 and the No. 2 rotating member 5 clamp the No. 1 drill rod 7, the protrusion 17 is located inside the groove 18, so that when the No. 1 drill rod 7 moves downward, the protrusion 17 slides inside the groove 18.

[0038] When the No. 1 drill rod 7 moves to the bottom of the No. 1 rotating member 4, the motor 6 is rotated in the opposite direction, and the turntable 13 can drive the slider 12 to move through the guide block 16. At this time, the No. 1 rotating member 4 and the No. 2 rotating member 5 are away from each other, and the No. 2 drill rod 9 is located between the two groups of clamps 28. The moving mechanism drives the two groups of clamps 28 and the No. 2 drill rod 9 to move toward the direction of the No. 1 rotating member 4, and pushes the No. 2 drill rod 9 between the No. 1 rotating member 4 and the No. 2 rotating member 5. The motor 6 rotates forward again, and the No. 1 rotating member 4 and the No. 2 rotating member 5 approach each other to clamp the No. 2 drill rod 9 and drive the No. 2 drill rod 9 to rotate.

[0039] When the rotating shaft 14 rotates, it drives the gear 24 to rotate synchronously. When the gear 24 rotates forward, the gear 24 does not contact the rack 25, and the rack 25 does not move. When the gear 24 rotates reversely, the gear 24 and the rack 25 contact, and the rack 25 moves in the direction of the rotating shaft 14 on the upper side of the cross plate 3. The rack 25 drives the connecting plate 33 to move synchronously. When the connecting plate 33 moves, it drives the two groups of clamping plates 28 and the mounting plate 26 to move synchronously, and the mounting plate 26 slides inside the movable groove 27.

[0040] When the mounting plate 26 stops moving, the connecting plate 33 continues to move, and the connecting plate 33 drives the adjusting member 31 to move through the spring 36, and the adjusting member 31 drives the push plate 32 to rotate, and the push plate 32 drives the two groups of clamping plates 28 to move away from each other through the connecting plate 33. It should be noted that magnets 29 are fixedly installed between the two groups of clamping plates 28, and the two groups of magnets 29 attract each other. When the two groups of clamping plates 28 move to the moving position, they stop moving, and the connecting plate 33 continues to move. The connecting plate 33 drives the adjusting member 31 to move synchronously through the rod 35, and the adjusting member 31 pushes the No. 2 drill rod 9 between the No. 1 rotating member 4 and the No. 2 rotating member 5. At this time, the spring 36 is deformed by the force, and the elastic force of the spring 36 is greater than the suction force between the two groups of magnets 29.

[0041] When drill rod No. 2 9 is located between rotating member No. 1 4 and rotating member No. 2 5, the limiting block 21 passes through the limiting groove 22 and falls into the interior of the mounting groove 19. At this time, the mounting block 20 is inserted into the interior of the mounting groove 19. Rotating member No. 1 4 and rotating member No. 2 5 drive drill rod No. 2 9 to rotate synchronously. When drill rod No. 2 9 drives the mounting block 20 and the limiting block 21 to rotate, drill rod No. 1 7 and drill rod No. 2 9 can be connected together. Under the action of the fixing block 23, drill rod No. 2 9 drives drill rod No. 1 7 to rotate synchronously.
