The first elastic wedge block 4041 can extend into the snap-fit ​​groove of the fixed seat 402 through its own elasticity, so that the fixed seat 402 and the connecting seat 404 are snapped together. A pull rope 4042 that passes through the connecting seat 404 is fixedly connected to one side of the first elastic wedge block 4041. Several sliding grooves corresponding to the pull rope 4042 are provided on the outer wall of the lower cylinder 301. The pull rope 4042 passes through the sliding grooves.

[0024] It also includes a return spring 406, and the bottom of several connecting seats 404 are connected to the bottom of the lower cylinder 301 by a return spring 406.

[0025] It also includes a pressing column 601, which is slidably connected to the top of the fixed base 402. The bottom of the pressing column 601 has a rectangular groove, and a second elastic wedge block 602 is connected in the rectangular groove. A wedge-shaped through groove 4021 is provided at the center of the top of the fixed base 402. The second elastic wedge block 602 can extend into the wedge-shaped through groove 4021 through its own elasticity, so that the pressing column 601 and the fixed base 402 are engaged.

[0026] It also includes a sounding plate 5. The bottom of the wedge-shaped through groove 4021 and the bottom of the second elastic wedge block 602 are both equipped with sounding plates 5. The two sounding plates 5 will make a sound when they collide.

[0027] It also includes a motor 603, the top of the lower pressure column 601 is fixedly connected to the output shaft of the motor 603, a drive ring 604 is fixedly installed on the outer wall of the fixed end of the motor 603, a number of first U-shaped rods 303 are slidably installed inside the drive ring 604, and the number of first U-shaped rods 303 are all fixedly connected to the upper cylinder 302. Three connecting rods 605 are fixedly connected to the outer wall of the drive ring 604, and one end of each of the three connecting rods 605 extends to the outside of the lower cylinder 301 and the upper cylinder 302, and a drive body 606 is fixedly connected to the outer wall of the lower cylinder 301 and the upper cylinder 302.

[0028] Working principle:

[0029] First, workers manually install drill bits 401 of different specifications into the lower cylinder 301. By manually removing the drill bits 401 and pushing them vertically upwards at the drill bit hole at the bottom of the lower cylinder 301, the drill bits 401 will drive the fixed seat 402 and the rotating ring 403 to move upwards synchronously. This causes the top of the rotating ring 403 to contact the first elastic wedge block 4041, causing the first elastic wedge block 4041 to contract. As the drill bits 401 continue to move upwards, the locking groove of the rotating ring 403 will engage with the connecting seat. Corresponding to the snap-fit ​​groove of 404, the first elastic wedge block 4041 is released elastically and extends into the snap-fit ​​groove of the rotating ring 403. Thus, the rotating ring 403 and the connecting seat 404 can be snapped together by the first elastic wedge block 4041, and the installation of the drill bit 401 can be completed. If the drill bit 401 needs to be replaced, the pull rope 4042 is pulled manually to retract the first elastic wedge block 4041, which will release the snap-fit ​​between the rotating ring 403 and the connecting seat 404. At this time, the drill bit 401 can be removed manually.

[0030] After the drill bit 401 is installed, the reducer housing 2 is installed onto the drill base 1 (the drill base 1 limits and fixes the reducer housing 2; this action is existing technology and will not be described in detail). Then, the drive body 606 is manually pulled to rotate counterclockwise around the lower cylinder 301 and the upper cylinder 302. The drive body 606 drives the drive ring 604 to rotate via the connecting rod 605. The drive ring 604 drives the lower pressure column 601 to rotate via the motor 603. At this time, the rotation of the lower pressure column 601 is a counterclockwise circular motion. During the rotation of the lower pressure column 601, it will contact the bottom of one of the lower pressure arcs 405 and squeeze the lower pressure arc 405, causing it to move downward. The lower pressure arc 405 drives the connecting seat 404 to move downward synchronously and compresses the return spring 406. Due to the sliding block 4043 is slidably connected to the lower cylinder 301. The connecting seat 404 and the pressing arc 405 can only slide vertically up and down. When the connecting seat 404 slides downward, it will drive the rotating ring 403 to slide downward synchronously through the first elastic wedge block 4041. The rotating ring 403 drives the drill bit 401 to move downward through the fixed seat 402, so that the bottom end of the drill bit 401 extends out of the drill hole of the lower cylinder 301. As the pressing column 601 continues to rotate, the pressing column 601 will pass over the pressing arc 405 and contact the top of the connecting seat 404. At this time, the drill bit 401 has moved downward to the lowest end. The pressing column 601 continues to rotate and will move to the center position of the top of the fixed seat 402. At this time, the wedge-shaped through groove 4021 corresponds to the second elastic wedge block 602. The elastic wedge block 602 extends out of the rectangular slot and enters the wedge-shaped through slot 4021, thereby engaging the pressure column 601 with the fixed seat 402 through the second elastic wedge block 602. Simultaneously, when the second elastic wedge block 602 enters the wedge-shaped through slot 4021, its bottom sound plate 5 collides with the sound plate 5 at the bottom of the wedge-shaped through slot 4021, producing a "snap" sound. When the operator hears this sound, they understand that the pressure column 601 and the fixed seat 402 are engaged. At this time, the drive body 606 is no longer rotated, and the drill bit 401 is fully extended. At this time, drilling can be performed directly on the reducer housing 2 through the drill bit 401. The motor 603 is started, and the motor 603 drives the pressure column 601 to rotate. At this time, the pressure column 601... The rotation described above is different from the rotation described above. The rotation of the lower pressure column 601 is a circular motion around the drive ring 604, which is a revolution. However, the rotation of the lower pressure column 601 at this time is not a circular motion, but a rotation on its own axis. The rotation of the lower pressure column 601 will drive the fixed seat 402 to rotate synchronously through the second elastic wedge block 602. The fixed seat 402 drives the drill bit 401 to rotate, allowing the drill bit 401 to perform drilling operations. During drilling, if the drill bit 401 needs to move up and down or adjust its position, the lower cylinder 301 and upper cylinder 302 can be moved as a whole through the drill seat 1 (the control of the lower cylinder 301 and upper cylinder 302 by the drill seat 1 for up and down movement, rotation, or position adjustment is existing technology and will not be described in detail). After drilling is completed...By controlling the drill bit 401 to move the lower cylinder 301 and upper cylinder 302 upwards as a whole, the drill bit 401 can be moved away from the reducer housing 2, at which point the reducer housing 2 can be removed.

[0031] When drilling with a different specification of drill bit 401 is required, the drive body 606 is manually rotated, and the above steps are repeated until the pressure column 601 revolves. At this time, the pressure column 601 will move at the top of the fixed seat 402. The second elastic wedge block 602 moves synchronously with the pressure column 601 and is squeezed by the wedge-shaped through groove 4021, causing the second elastic wedge block 602 to retract into the rectangular groove. It is worth noting that when the pressure column 601 and the fixed seat 402 are engaged by the second elastic wedge block 602, the pressure column 601 can drive the fixed seat 402 to rotate synchronously. However, due to the presence of the wedge-shaped through groove 4021, the revolution of the pressure column 601 will not be affected. When the pressure column 601 revolves and passes the wedge-shaped through groove 4021 and the fixed seat 402, the second elastic wedge block 602 has completely retracted into the rectangular groove at the bottom of the pressure column 601. As the pressure column 601 continues to rotate, the pressure column 601 will move further into the rectangular groove at the bottom of the pressure column 601. The rotating ring 403 and connecting seat 404 pass through the rotating ring 403 and contact the bottom of the next pressing arc 405. It is worth noting that at this time, the connecting seat 404 is at its lowest point, which corresponds to the bottom of the next pressing arc 405. This allows the pressing column 601 to pass over the connecting seat 404 and contact the bottom of the next pressing arc 405. Then the pressing column 601 continues to rotate and no longer contacts the connecting seat 404. The above steps are repeated. After the connecting seat 404 and the pressing column 601 are no longer in contact, the return spring 406 is released, which drives the connecting seat 404 to slide upward and reset. The connecting seat 404 drives the rotating ring 403 to slide upward synchronously through the first elastic wedge block 4041. The rotating ring 403 drives the drill bit 401 to be retracted into the lower cylinder 301 through the fixed seat 402. Thus, different specifications of drill bits 401 can be changed by rotating the drive body 606. The operation is simple and the applicability is high.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
