[0020] In this embodiment, please refer to Figure 8 , Fig.10 , Fig.11 A locking groove 25 is provided on the inner side of the connecting seat 21, one end of the second tilting shaft 35 is located in the inner cavity of the locking groove 25, a movable bolt 351 is provided in the inner cavity of the second tilting shaft 35, one end of the movable bolt 351 is provided with a second threaded shaft 352, the outer side of the second threaded shaft 352 and the inner cavity of the second tilting shaft 35 are provided with mutually adapted threaded structures, a pressing bead 353 is provided at the bottom end of the second threaded shaft 352, and a plurality of positioning beads 355 are also provided in the inner cavity of the second tilting shaft 35, and the positioning beads 355 are located at the pressing bead On one side of 353, the inner cavity of the locking groove 25 is provided with a positioning hole 251 that is compatible with the positioning bead 355. In this embodiment, the movable bolt 351 is rotated by external force to control the second threaded shaft 352 to move downward, so that the second pressing bead 353 pushes the positioning bead 355 to move outward, so that the positioning bead 355 enters the inner cavity of the positioning hole 251, and the second inclined shaft 35 is fixed in the inner cavity of the locking groove 25, so that the position of the fixing seat 31 is fixed, and the drill body 32 is fixed at this angle for processing operations.

Due to the characteristics of the worm 23 and the worm wheel 24, the worm wheel 24 can only be driven to rotate by the worm 23, and the worm wheel 24 cannot drive the worm 23 to rotate, so that after the angle adjustment of the drill body 32 is completed, the first tilting shaft 34 will not rotate due to vibration, thereby further maintaining the stability of the drill body 32.

[0023] In this embodiment, please refer to Figure 7 A No. 1 threaded shaft 22 is provided at one end of the mounting seat 2, and the No. 1 threaded shaft 22 cooperates with the inner cavity thread of the mounting seat 2. By controlling the rotation of the No. 1 threaded shaft 22, one end of the connecting seat 21 can be moved forward and backward along the inner cavity of the mounting seat 2. In this embodiment, the No. 1 threaded shaft 22 is controlled to rotate by external force, so that one end of the connecting seat 21 can be moved forward and backward, thereby moving the position of the drilling rig 3 fixed on the inner side of the connecting seat 21, and cooperating with the orientation adjustment of the mounting seat 2 to further increase the operating range of the drilling rig 3.

[0024] In this embodiment, please refer to Fig. 9 The angle adjustment range of the drill body 32 is from the initial position perpendicular to the base 11 until the axis of the drill body 32 is parallel to the plane of the base 11. In this embodiment, the drill body 32 can cope with the inclined drilling requirements under various complex working conditions. It is no longer limited to traditional vertical operations, and the drill body 32 can also be used to process flat walls.

[0025] Working principle of the present invention: Step 1: The driving motor is used to give power to control the rotation of the lead screw 13. According to the transmission principle of the ball screw, the lead screw nut 14 is moved up and down along the lead screw 13 by controlling the rotation of the lead screw 13. The lead screw nut 14 is moved up and down to drive the mounting seat 2 to move up and down along the outer side of the drilling rig body 1. By controlling the rotation direction of the screw 13, the mounting seat 2 can be controlled to move up or down, and the height of the drilling rig 3 can be adjusted by controlling the movement of the mounting seat 2. The ball screw is used for transmission so that the movement of the drilling rig 3 has high precision and can meet the requirements of precise positioning. At the same time, the stepper motor 111 drives the No. 1 gear 112 to rotate. Since the outer edge of the No. 1 gear 112 is meshed with the outer edge of the No. 2 gear 113, the No. 1 gear 112 drives the No. 2 gear 113 to rotate. The rotation of the No. 2 gear 113 can make the drill frame body 1 rotate along the top of the base 11. The direction of the drill rig 3 is changed according to the rotation of the base 11. By rotating the No. 1 threaded shaft 22, a section of the connecting seat 21 is moved in the inner cavity of the mounting seat 2, so that the overall length of the mounting seat 2 can be extended, thereby making the processing range of the drill rig 3 wider.

[0026] Step 2: Push the push button 413 to push the push rod 412 forward. Since the push rod 412 and the linkage block 411 are arranged as corresponding inclined surfaces, the push rod 412 moves forward to push the linkage block 411 to move toward the two ends of the inner cavity of the positioning frame 41, so that the two transmission rods 42 move along the inner wall of the slide groove 414, so that the distance between the two reset frames 43 gradually increases, and the spring 431 is squeezed and deformed, so that the two clamping rings 44 move back and forth, so that one side of the clamping ring 44 is no longer in contact with the outer side of the brake wheel 45, so that the locking After the block 441 and the brake block 451 are no longer in contact, the brake wheel 45 is not blocked and can rotate normally. At this time, the lead screw 13 can be driven to rotate to adjust the height of the mounting seat 2. After the mounting seat 2 is adjusted to a suitable height, stop pressing the button 413, so that the spring 431 loses pressure and rebounds, so that the reset frame 43 drives the two clamping rings 44 to move toward each other, so that the clamping rings 44 return to their original positions, so that the locking block 441 and the brake block 451 block each other, so that the brake wheel 45 cannot rotate, thereby fixing the position of the mounting seat 2 at the adjusted height; Step 3: Rotate the turning handle 231 by external force to drive the worm 23 to rotate, and the rotation of the worm 23 drives the worm wheel 24 to rotate, and the rotation of the worm wheel 24 drives the first tilting shaft 34 to rotate, and the first tilting shaft 34 provides power to change the tilting angle of the fixing seat 31, and cause the second tilting shaft 35 to rotate. After the tilting angle of the drill body 32 is aligned with the position to be processed, the movable bolt 351 is rotated by the tool, and the second threaded shaft 352 is driven to rotate by the movable bolt 351. Since the outer side of the second threaded shaft 352 and the inner wall of the second tilting shaft 35 are provided with mutually compatible threaded structures, the control The rotation direction of the movable bolt 351 can make the second threaded shaft 352 move downward, and the downward movement of the second threaded shaft 352 can make the pressing ball 353 move downward, and the downward movement of the pressing ball 353 can squeeze the multiple positioning beads 355 outward, and make the elastic ring 354 deformed by pressure, and when the positioning bead 355 moves outward, it enters the inner cavity of the positioning hole 251, so that the second tilting shaft 35 is fixed in the inner cavity of the locking groove 25, so that the second tilting shaft 35 cannot rotate, so that the tilt angle of the drill body 32 is fixed, and the angle of the drill body 32 is prevented from being offset due to vibration during the processing.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
