The upper end of the sliding groove 9 is connected with the groove 12. A connecting block 21 and a positioning block 10 are slidably arranged in the groove 12. A rack 1 is fixedly arranged at the lower end of the positioning block 10. A gear ring is fixedly connected to the outside of the plurality of rotating blocks 5, and the rack 1 is correspondingly meshed with the gear rings on the plurality of rotating blocks 5. A sliding hole 15 is provided at one end of the front side of the sliding groove 9 away from the side folding edge 1, and the sliding hole 15 is slidably connected to the sliding block 13, and the sliding block 13 corresponds to the positioning hole 3, and the sliding block 13 is fixedly connected to the control block 14. A matching hole 19 is provided on the side of the sliding block 13 away from the control block 14, and the inclined end of the matching hole 19 contacts the inclined end of the matching block 20 correspondingly, and the horizontal end of the matching block 20 is fixedly connected to the lower end of the connecting block 121, and the connecting block 121 is slidably connected to the front side of the groove 12, and the positioning block 10 is slidably connected to the rear side of the groove 12.

Figure 1After the screw thread is tightened, the sliding shell 7 is pushed to slide along the connecting plate 4. The front end of the sliding groove 9 is an open structure. The length of the sliding groove 9 is greater than the length of the connecting plate 4, so that the sliding shell 7 can slide along the connecting plate 4 until the rear end of the connecting plate 4 contacts the rear end of the sliding groove 9. At this time, the sliding shell 7 cannot slide along the connecting plate 4, and the sliding block 13 just moves to the position of the positioning hole 3. At this time, the connecting plate 4 is no longer at the front side of the sliding groove 9, and will not block the sliding block 13. The sliding block 13 is released. Under the elastic action of the spring rod 1 18 in the compressed state, the connecting block 2 17 moves toward the direction of the side folding edge 1, thereby driving the sliding block 13 to move until the sliding block 13 is aligned with the positioning hole 3 on the side folding edge 1.

After the pressing block 28 contacts the bottom plate 8 and cannot move, the spring rod three 27 is compressed. Under the elastic force of the spring rod three 27, the pressing block 28 provides downward pressure on the bottom plate 8, so that the bottom plate 8 remains stable during the drilling process, avoiding the bottom plate 8 from deviating during the drilling process and causing drilling failure.

[0025] Example 4 On the basis of Example 3, Figure 4-Figure 5 As shown, the heat dissipation and lubrication mechanism includes a liquid storage chamber 6 disposed inside the top seat 23, the liquid storage chamber 6 is connected to the bellows 32, the bellows 32 is connected to the through hole 33 on the connecting plate 26, the through hole 33 is connected to the delivery pipe 38, the delivery pipe 38 is connected to the nozzle 39, and the nozzle 39 is disposed correspondingly to the drill bit 31; The heat dissipation and lubrication mechanism also includes a sealed heat-insulating shell 44, which is fixedly arranged at the lower end of the connecting plate 26, and the lower end of the sealed heat-insulating shell 44 is rotatably connected to the movable end of the driving telescopic rod 16, and a sealed heat-insulating cavity 43 is provided inside the sealed heat-insulating shell 44, and a sealing plate 40 is slidably provided in the sealed heat-insulating cavity 43, and a spring rod 4 is fixedly provided between the sealing plate 40 and the side end of the sealed heat-insulating cavity 43, and the sealing plate 40 is fixedly connected to the rack 2 37, and the rack 2 37 is meshed with the lower side of the gear 35, and the gear 35 is meshed with the lower side of the gear 35. The sealing and heat preservation chamber 43 is rotatably arranged in the movable opening 36, the sealing and heat preservation chamber 43 is communicated with the blocking chamber 11 through the movable opening 36, the blocking chamber 11 is communicated with the through hole 33, the blocking chamber 11 is arranged inside the connecting plate 26, the movable opening 36 is arranged at the lower end of the connecting plate 26, the sealing and heat preservation chamber 43 is communicated with the blocking chamber 11 through the movable opening 36, a blocking block 34 is slidably arranged in the blocking chamber 11, a rack 3 is fixedly arranged at the lower end of the blocking block 34, the rack 3 is meshed with the upper side of the gear 35, and the blocking block 34 is used to block the through hole 33.

[0026] The beneficial effects of the above technical solution are: The liquid storage chamber 6 is used to store lubricating liquid. A liquid replenishing port is provided at the upper end of the liquid storage chamber 6 to facilitate liquid replenishing. Under the action of gravity, the lubricating liquid in the liquid storage chamber 6 flows into the bellows 32. When drilling a hole in the bottom plate 8, the nozzle 39 is opened to allow the lubricating liquid to flow to the nozzle 39 through the bellows 32, the through hole 33 and the delivery pipe 38. The nozzle 39 sprays the lubricating liquid onto the blade of the drill bit 31, which plays a role in heat dissipation and lubrication for the drill bit 31 during the drilling process. If the temperature between the drill bit 31 and the bottom plate 8 rises due to friction during the drilling process, the temperature of the active end of the driving telescopic rod 16 connected to the drill bit 31 rises. The active end of the driving telescopic rod 16 is made of a material with good thermal conductivity, thereby increasing the temperature of the air in the sealed heat-insulating chamber 43 connected thereto. Under the action of thermal expansion and contraction, the sealing plate 40 moves in a direction away from the active end of the driving telescopic rod 16, and the sealing plate 40 drives the spring rod four to be compressed, and the sealing plate 40 drives the rack two 37 to move. When the rack 2 37 moves, it drives the gear 35 to rotate, the gear 35 drives the rack 3 to move, and the rack 3 drives the blocking block 34 to move, and the moving direction of the blocking block 34 is opposite to the moving direction of the sealing plate 40, so that the blocking area of ​​the through hole 33 by the blocking block 34 is gradually reduced, thereby increasing the injection flow rate of the lubricating liquid by the nozzle 39, improving the heat dissipation effect on the drill bit 31, and ensuring the drilling quality of the drill bit 31. If the temperature drops, the sealing plate 40 is driven to move toward the direction close to the active end of the driving telescopic rod 16 under the elastic action of the spring rod 4. At this time, under the action of the rack 2 37, the gear 35 and the rack 3, the blocking block 34 moves toward the through hole 33, increasing the blocking area of ​​the through hole 33, reducing the injection flow rate of the lubricating liquid by the nozzle 39, and avoiding the waste of the lubricating liquid. The setting of the heat dissipation and lubrication mechanism can automatically adjust the injection flow rate of the lubricating liquid, which not only ensures the normal operation of the drill bit 31, but also avoids the waste of the lubricating liquid.
