[0029] refer to Figure 1 , a column 8 is symmetrically fixedly arranged on the top surface of the movable plate 15, and a rectangular groove 19 is opened on the inner side of the column 8, a guide rod 10 is fixedly arranged in one of the rectangular grooves 19, and a screw 2 11 is rotatably arranged in the other rectangular groove 19, and a motor 2 12 is fixedly arranged on the top surface of the column 8 with the screw 2 11, and the output shaft of the motor 2 12 passes through and rotates on the top surface of the column 8 and is fixedly connected to one end of the screw 2 11,

[0030] refer to Figure 1-2 The screw 11 is threaded with a U-shaped moving platform 13, and the other end of the U-shaped moving platform 13 is sleeved and slid on the guide rod 10. The height adjustment of the U-shaped moving platform 13 can be achieved through the cooperation of the motor 12 and the screw 11, thereby providing the prerequisite for subsequent drilling holes on the side of wood of different thicknesses.

[0031] refer to Figure 1-3 A telescopic cylinder 14 is fixedly arranged in the middle of one side of the U-shaped moving platform 13, and a moving plate 2 15 is fixedly arranged at the moving end of the telescopic cylinder 14, and both sides of the moving plate 2 15 are limited and slide on the inner side of the U-shaped moving platform 13.

[0032] refer to Figure 3 A step groove 16 communicating with the bottom of the U-shaped moving platform 13 is provided on the top surface of the U-shaped moving platform 13, and a plurality of blocks 17 are slidably arranged in the step groove 16. A motor 3 18 is fixedly arranged on the side of the block 17 away from the telescopic cylinder 14. A rectangular plate 19 is fixedly arranged on the top surface of the U-shaped moving platform 13, and a slide groove 3 20 is provided on the rectangular plate 19. A drill bit 21 is fixedly arranged at the output end of the motor 3 18, and the drill bit 21 passes through and moves in the slide groove 3 20.

[0033] refer to Figure 3-4A plurality of slide grooves 4 23 are provided on the movable plate 2 15 , wherein the middle slide groove 4 23 is in a vertical state, and the other slide grooves 4 23 are evenly arranged at both sides at equal angles with the vertical slide groove 4 23 as the middle axis, and the top ends or tail ends of all the slide grooves 4 23 are on the same horizontal line.

[0034] refer to Figure 3 , 7 The bottom surface of the block 17 is fixedly provided with a limiting column 22, and all the limiting columns 22 are respectively inserted and slid in the corresponding four slide grooves 23. It should be noted that the number of the limiting columns 22 is adapted to the number of the four slide grooves 23.

[0036] When it is necessary to drill holes on the side of wooden boards of different thicknesses, the motor 2 12 can be started so that the motor 2 12 drives the lead screw 2 11 to rotate. The rotation of the lead screw 2 11 will drive the U-shaped movable platform 13 to adjust the position in the vertical direction, and then the height of the drill bit 21 can be adjusted to ensure that the drill bit 21 can be adjusted to the middle position of the side of the wood of different thicknesses. Then the motor 14 is started again, and the motor 14 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the movable plate 15 to gradually move toward the side of the wood, so that the drill bit 21 gradually moves toward the side of the wood. The depth of the hole drilled by the drill bit 21 can be controlled by the moving distance of the movable plate 15. In the process of the drill bit 21 moving toward the side of the wood, the motor 3 18 is started, and the motor 3 18 drives the drill bit 21 to start rotating at high speed, so as to realize the side drilling of wood of different thicknesses.

[0037] When drilling holes on the sides of wood with different widths is required, the telescopic cylinder 14 is first started, so that the moving end of the telescopic cylinder 14 pushes or pulls the moving plate 2 15. When the telescopic cylinder 14 pushes the moving plate 2 15 (refer to Figure 3), the movable plate 2 15 gradually moves away from the fixed end of the telescopic cylinder 14, and relatively speaking, the plurality of limit posts 22 will gradually move to the tail end of their respective slide grooves 4 23, that is, the plurality of limit posts 22 are evenly close to each other, so that the plurality of blocks 17 are equidistantly contracted, so that the drill bit 21 moves and contracts equidistantly, and can adapt to the drilling of the side of the wood with a smaller width. On the contrary, when the telescopic cylinder 14 pulls the movable plate 2 15, the movable plate 2 15 gradually approaches the fixed end of the telescopic cylinder 14, and the plurality of limit posts 22 are limited by the slide grooves 4 23, and the plurality of limit posts 22 are gradually equidistantly expanded, so that the distance in the bracket of the drill bit 21 can be evenly adjusted, and can adapt to the drilling of the side of the wood with a larger width. In summary, the movable plate 2 15 can be pushed or pulled by the telescopic cylinder 14 to evenly adjust the distance between the drill bits 21, and thus realize the drilling of the side of the wood with different widths.

[0038] Embodiment 2:

[0039] On the basis of or different from the first embodiment, reference Figure 5-6 8. A boss 27 is fixedly provided on the top surface of the workbench 1 away from the drill bit 21.

A motor four 31 is fixedly arranged on one side of the boss 27, and the output shaft of the motor four 31 passes through and rotates on the side of the boss 27 and is fixedly connected to one end of the bidirectional lead screw three 30. The different thread segments of the bidirectional lead screw three 30 are threadedly matched with a moving part 32, and the upper end of the moving part 32 slides in contact with the slide groove five 28.

[0041] refer to Figure 5 Rectangular grooves 33 are provided on the opposite surfaces of the two moving parts 32, and clamps 34 are slidably arranged in the rectangular grooves 33. Telescopic cylinders 35 are fixedly arranged on the top surfaces of the moving parts 32. The moving ends of the telescopic cylinders 35 pass through and slide on the top surfaces of the moving parts 32 and are fixedly connected to the top surfaces of the clamps 34.

[0042] The motor 4 31 can be started to drive the bidirectional lead screw 30 to rotate, and then the different threaded parts of the bidirectional lead screw 3 drive the two moving parts 32 to move closer to or away from each other, thereby adjusting the distance between the two clamps 34, so that wood of different widths can be clamped. The height of the clamp 34 can be adjusted by the telescopic cylinder 2 35, so that wood of different thicknesses can be clamped.
