[0026] The pulling mechanism 5 includes a sliding block 501, a hydraulic cylinder 502, a piston rod 503, a pulling rope 504 and a hook 505. The sliding block 501 is slidably connected to the lower surface of the mounting base 3. A T-shaped connecting block is provided on the upper surface of the sliding block 501. The T-shaped connecting block of the sliding block 501 is fitted in the T-shaped groove of the mounting base 3. The hydraulic cylinder 502 is fixedly connected to the lower surface of the sliding block 501. The piston rod 503 is fixedly connected to the output end of the hydraulic cylinder 502. The pulling rope 504 is fixedly connected to the bottom end of the piston rod 503. The hook 505 is fixedly connected to the pulling rope 504. When using the pulling mechanism 5, it is necessary to move the sliding block 501 to the innermost position of the T-shaped groove. After the drill bit 1 is installed, it is necessary to remove the pulling mechanism 5.
[0027] A limiting plate 4 is fixedly connected to the left side surface of the mounting base 3. The limiting plate 4 is L-shaped. A hanging ring 11 is fixedly connected to the upper surface of the drill bit 1. The number of the hanging rings 11 is two and they are distributed centrosymmetrically about the axis of the drill shank 2. When the hanging ring 11 and the hook 505 are engaged and the drill bit 1 is pulled up, when the drill bit 1 rises to the highest position, the first mating groove 201 coincides with the second mating groove 302.

[0029] The left and right side surfaces of the mounting base 3 are fixedly connected to the first fixing plate 8. A through-round hole is provided on the upper surface of the first fixing plate 8.

[0030] Working principle: During installation, the upper pulling mechanism 5 is installed on the mounting base 3. Then, the hook 505 is hung on the hanging ring 11. Subsequently, the hydraulic cylinder 502 is started to drive the drill bit 1 to move upward until the drill handle 2 is pulled to the highest position. At this time, the first mating groove 201 and the second mating groove 302 coincide. Then, the locking rod 6 is inserted into the second mating groove 302 and the first mating groove 201 until the locking rod 6 contacts the limiting plate 4, thereby fixing the position of the drill handle 2 in the mounting base 3. Subsequently, the angle of the rotating rod 13 is adjusted to release the restriction on the position of the pulling plate 10. At this time, the sliding shaft 7 moves downward under its own gravity and the pulling of the spring 9 and is inserted into the second mating hole 601 of the locking rod 6, thereby restricting the position of the locking rod 6 and preventing the locking rod 6 from slipping out of the mounting base 3 during the rotation of the drill bit 1. Finally, the upper pulling mechanism 5 is removed to complete the fixation of the drill bit 1. The whole process is simple and easy.
