When in specific use:

the drill bit 6 and the spiral rotary head 2 are used separately, the spiral rotary head 2 is used for grinding burrs, the drill bit 6 is used for punching, and the drill bit 6 and the spiral rotary head cannot interfere with each other when in use.

In the actual operation process, the general operation sequence is to eliminate the burrs first, and the punching provides a fixed foundation for sewing up the subsequent operation rope.

It should be noted that the helical rotary head 2 requires a driving device to drive the rotary head of the helical rotary head 2 in actual operation, and the drill 6 may or may not use the driving device, and may be directly rotated manually.

During initial position, use spiral shell rotary head 2 earlier, therefore, with right hand (left hand) thumb, forefinger and middle finger grip pull ring 11, upwards lift, make slider 12 remove in T type fluting 10, thereby stay cord 13 drives pulley 9 and rotates, pulley 9 coaxial drive drill bit 7 outwards overturns, make drill bit 7 overturn the outside of spiral shell rotary head 2 from the outside of spiral shell rotary head 2, press close to the outside of sleeve 4, at this moment, spiral rotary head 2 exposes outside, then rotate pull ring 11, make slider 12 move the horizontal position of T type fluting 10, according to the in-service use direction, select the horizontal groove position of suitable T type fluting 10, with slider 12 joint in the extension groove.

Conversely, when the drill bit 6 is used, the slider 12 is slid out of the extension slot, and the pull ring 11 is rotated so that the slider 12 moves from the lateral slot to the vertical slot of the T-slot 10, at which time the drill bit 7 is turned to the outside of the helical rotary head 2.

The operation rope shell is installed on drill bit 6, and the upset of piece 7 is bored in the pulling pull ring 11 can be adjusted to the pulling to make piece 7 carry out inside expanding to the operation rope and prop, the operation rope shell can not drop, rotates sleeve 4, and sleeve 4 takes drill bit 6 forward motion, thereby stretch into the downthehole that drill bit 6 bored with the operation rope shell, and carousel 29 is used for the unwrapping wire, kinked and the cutting line of operation rope, and friction disk 30 is used for the fixed with carousel 29, but not dead fixed.

The thumb is used for rotating the poking wheel 39, the poking wheel 39 is meshed with the first gear 37 to rotate, the first gear 37 drives the second rotating shaft 36 to rotate, the second rotating shaft 36 drives the cam 35 to rotate, the lower portion of the meshing portion is jacked up when the cam 35 rotates, the meshing portion rotates, the opening at the upper end of the meshing portion is opened and closed, when the cam 35 jacks up the meshing portion, the first spring 33 stretches, the meshing portion opens, and when the first spring 33 resets, the opening of the meshing portion closes.

The opening and closing of the occlusion part can realize that the operation rope is placed in the occlusion part to be pulled.

In the second embodiment, specifically, the first annular sliding block 15 is fixed on the first cylinder 1, the first annular sliding rail 15 is disposed on the inner side wall of the first sleeve 4, and the first sliding block 15 can rotate in the first sliding rail 14, so as to ensure that the first cylinder 1 drives the spiral rotating head 2 to rotate when rotating normally, and the first sleeve 4 does not rotate.

In the third embodiment, specifically, the drill bit 7 needs to have a rotating part, the rotating part is provided with brackets 16, the number of which is matched with that of the drill bits 7, on the outer side wall of the first sleeve 4, namely, 4 in total, the brackets 16 are arranged obliquely at an angle, a first rotating shaft 17 is arranged at the end of each bracket 16, the drill bits 7 are fixed on the first rotating shaft 17, the first rotating shaft 17 is coaxially connected with the pulley 9, and the first rotating shaft 17 is sleeved with the coil spring 18.

When the spiral rotating head is used, when the drill bit 7 is arranged on the outer side of the spiral rotating head 2 and is in a standing state, a space 8 is reserved between every two drill bits 7, the tip of each drill bit 7 is in a circular hollow shape, the circular shape is small, the use of drilling is not influenced, the spiral spring 18 enables the drill bits 7 to have pressing force deviating from the direction of the spiral rotating head 2, and after the drill bits 7 are pulled, the spiral spring 18 starts to be in a stress state.

In the fourth embodiment, specifically, the length of the drill bit 7 is greater than that of the spiral rotary head 2, so that the drill bit 7 can wrap the spiral rotary head 2 inside (not completely and hermetically wrapped), and the distance from the end of the upper end of the second sleeve 5 to the end of the upper end of the first sleeve 4 is greater than that of the drill bit 7.

This allows the spiral rotary head 2 to be placed in the drill bit 6, and when the drill bit 7 is pulled, the drill bit 7 starts to turn over, and the turned-over drill bit 7 does not contact the second sleeve 5 yet, so as to prepare for the subsequent drill bit 7 to enter the inner side wall of the second sleeve 5.

In the fifth embodiment, the first end of the column body 1 far away from the spiral rotating head 2 is fixedly connected with the clamping block 19, the whole appearance of the clamping block 19 is of a gamma shape, the concrete explanation is that the clamping block 19 is divided into a horizontal transverse block 20 and a vertical block 21 which are integrally connected, the left end of the horizontal transverse block 20 is provided with a vertical transverse block groove 22, the horizontal transverse block groove 22 does not penetrate through the horizontal transverse block 20, the lower left corner of the vertical block is provided with a vertical block groove 23, the vertical block groove 23 does not penetrate through the vertical block 21, however, the opening directions of the vertical block groove 23 and the horizontal block groove 22 are on two different surfaces, the left boundary and the right boundary of the vertical block groove 23 are communicated with the outside, and the middle of the right side line of the vertical block 21 is provided with a semi-rectangular through hole 24.

The joint block 19 can be dismantled and be connected with rather than the installation piece 25 that cooperates the use, and the structure of installation piece 25 sets up with joint block 19 symmetry, and is vertical piece one and horizontal piece one in corresponding vertical piece groove 23 and horizontal piece groove 22 department, and joint block 19 and the half rectangle through-hole 24 on the installation block 25 constitute a complete rectangle through-hole, and this complete rectangle through-hole department can be dismantled and peg graft and have a voussoir 27.
