[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-4It can be known that when the drill component 11 is replaced by the utility model, the driving assembly drives the ring 7 to rotate on the mounting plate 3, driving multiple drill components 11 of different models to rotate, and the drill component 11 to be used is rotated to the bottom of the drill motor 8 according to the needs, and the drill motor 8 and the drill component 11 are docked through the limit assembly 9. The drill motor 8 drives the drill component 11 to rotate, and the cylinder 6 controls the movement of the mounting plate 3 to complete the drilling operation. The drill component 11 is a prior art, which can be installed on the ring 7 and rotated to realize the drilling operation. Specifically, the rotation of the ring 7 drives the drill component 11 and the alignment block 95 to rotate, such as Figure 1 As shown, the ring 7 rotates clockwise, when the left side of the alignment block 95 contacts the right side of the movable plate 92, that is, the alignment block 95 is located on the right side of the movable plate 92. Since the movable plate 92 is vertically slidably arranged in the fixed sleeve 91, and the contact surface between the alignment block 95 and the movable plate 92 is a curved surface 99, the movable plate 92 is moved into the fixed sleeve 91 under the influence of the thrust, and the compression spring 94 is compressed. The alignment block 95 continues to rotate with the ring 7, so that the alignment block 95 slides directly under the movable plate 92, and the movable plate 92 is ejected by the force of the compression spring 94. At this time, the alignment block 95 is located on the left side of the movable block, which is also That is, the movable plate 92 is located on one side of the limiting groove 96 of the alignment block 95. At this time, the driving assembly drives the ring 7 to rotate in the opposite direction, that is, counterclockwise, so that the alignment block 95 and the limiting groove 96 slide toward the lower end of the movable plate 92. When the drill component 11 is completely located directly below the movable plate 92, the movable plate 92 with a square bottom is just completely inserted into the matching limiting groove 96. In this process, the insertion rod 97 is also just inserted into the insertion hole 98. Through the limitation of the square limiting groove 96 and the limitation of the insertion rod 97 and the insertion hole 98, the drill motor 8 can drive the drill component 11 to rotate. The whole process does not require personnel to manually disassemble and install the drill bit, which improves the installation efficiency of the drill bit.

[0023] The movable plate 92 and the inner wall of the fixed sleeve 91 are vertically slidably connected via a sliding member 93, thereby ensuring the stability of the vertical movement of the movable plate 92 and also ensuring the stability of driving the drill head component 11 to rotate after subsequent docking.

[0024] Among them, the alignment block 95 is slidably connected to the mounting plate 3 through the limiter 15, so that the non-working drill bit is relatively stable, and it is also ensured that when the movable plate 92 is docked, one side of the curved surface 99 contacts the movable plate 92 first. Other existing technologies can also be used to achieve this purpose.

[0025] Among them, the driving component includes a servo motor 10, a bevel gear 13 and a bevel gear ring 14. The bevel gear ring 14 is arranged on a circle on the side surface of the ring 7. The servo motor 10 is arranged on the mounting plate 3. The output end of the servo motor 10 rotates to drive the bevel gear 13 to rotate. Since the bevel gear 13 is meshed and connected with the bevel gear ring 14, it can drive the bevel gear 13 and the ring 7 to rotate. The matching relationship between the servo motor 10, the bevel gear 13 and the bevel gear ring 14 makes the transmission more stable and accurate.

[0026] The fixture on the workbench 1 of the utility model can adopt the existing technology, and no detailed description is given here; the drawings in the specification are schematic diagrams used to explain the working principle and do not represent real gears and specifications.
