When the spool 78 is required to be paved towards the bottom of the groove 1 by using the spool, the spool is firstly arranged above the notch of the groove 1, so that the shell 8, the two side holding plates A12 and the two side holding plates B19 at the lower end of the sliding column 7 are positioned in the range of the groove 1 along the length direction of the groove 1, and then the distance between the two rows of rotating shafts C39 in the two side holding plates A12 along the direction perpendicular to the movement of the spool 78 in the groove 1 is adjusted according to the diameter of the spool 78 to be paved in the groove 1, so that the distance between the two rows of rotating shafts C39 is larger than the diameter of the spool 78 to be conveyed.
The procedure for adjusting the spacing between the two rows of shafts C39 in the direction perpendicular to the movement of the conduit 78 in the channel 1 is as follows:
the crank B77 is rocked, the crank B77 drives two gears I62 to synchronously rotate in the same direction through a worm 76, a worm wheel 75, a rotating shaft I73, a gear N72, a gear M71, a rotating shaft H70, a gear L69, a gear K68, a rotating shaft G66, a gear J65 and a rack B63, the two gears I62 respectively drive two sliding seats 36 to move in opposite directions or back to back through two racks A61 at corresponding side ends, and the two sliding seats 36 respectively drive a corresponding row of rotating shafts C39 to move in a direction perpendicular to the movement of a spool 78 in a groove 1 until; when the distance between the two rows of rotating shafts C39 is larger than the diameter of the wire pipe 78 to be conveyed, the shaking of the crank B77 is stopped, and the distance between the two rows of rotating shafts C39 can be adjusted.
Then, the tip interval between the two side holding plates a12 and the tip interval between the two side holding plates B19 are aligned with the line pipe 78 which is disposed flat at the bottom of the groove 1.

When the tail ends of the two side holding plates B19 meet the bottom of the groove 1, as the sliding column 7 drives the two side holding plates A12 and the two side holding plates B19 to continuously move towards the bottom of the groove 1 through the shell 8, the two side holding plates B19 swing towards the direction of the spool 78 around corresponding rotating shafts A22 respectively and gradually form a package to the spool 78, four spiral springs A24 reset to each side holding plate B19 are further compressed, the rotating shafts A22 drive the corresponding two ratchet wheels 25 to synchronously rotate, and at the moment, the rotation of the two ratchet wheels 25 is not limited by corresponding pawls 26. Each pawl 26 reciprocates under the action of the corresponding two spiral springs B28 and ratchet 25.
When the ends of the two side holding plates A12 meet the bottom of the groove 1, the swing of the two side holding plates B19 stops and abuts against the bottom of the groove 1, and the two side holding plates B19 are in a binding state for the spool 78. In the process of wrapping and restraining the spool 78 by the two side holding plates B19, the spool 78 is lifted to a small height, the pressing load of the spool 78 on the two side holding plates B19 caused by the small height is small, the load can be ignored, extra power of equipment is not consumed, the energy-saving effect is achieved, the power requirement on the equipment is low, and the conveying cost of the spool 78 is low.
In the process of the two side holding plates B19 for restraining the spool 78, the ratchet wheels 25 on the two side holding plates B19 are respectively matched with the corresponding pawls 26, so that the two side holding plates B19 still keep the restraining state of the spool 78 under the gravity action of the spool 78 and do not swing back.
When the ends of the two side holding plates abut against the bottom of the groove 1, the rocking of the crank a18 is stopped, and at this time, the spool 78 has entered between the two side holding plates a12 and is located between the two rows of rotation shafts C39.

And then the crank A18 is rocked to enable the sliding column 7 to drive the two side holding plates A12 and the side holding plate B19 at the lower end of the shell 8 to move towards the bottom of the groove 1. When the ends of the two side holding plates a12 are abutted against the bottom of the groove 1, the two wire pipes 78 enter between the two side holding plates a12 and are lifted up by a small height by the two side holding plates B19 and are folded and restrained, and at this time, the rocking of the crank a18 is stopped. Then, the crank B77 is rocked, and the crank B77 drives the two rows of rotating shafts C39 to laterally squeeze the two wire pipes 78 through a series of transmission, so that effective friction is formed between the rubber sleeve 40 on the two rows of rotating shafts C39 and the two wire pipes 78. Finally, the electric driving module 60 is started, and the electric driving module 60 drives the two rows of rotating shafts C39 to rotate through a series of transmission and conveys and lays the two wire pipes 78 into the groove 1 along the length direction of the groove 1.

With the two side clasping plates B19 open to both sides, the spool 78 is disengaged from the present invention vertically downward from between the two side clasping plates B19 and the two side clasping plates a 12.

then, the crank (B77) is rocked, the crank (B77) drives the two rows of rotating shafts (C39) to laterally squeeze the two wire pipes (78) through a series of transmission, and effective friction is formed between the rubber sleeve (40) on the two rows of rotating shafts (C39) and the two wire pipes (78); finally, starting the electric driving module (60), and driving the two rows of rotating shafts (C39) to rotate by the electric driving module (60) through a series of transmission and conveying and paving the two wire pipes (78) into the groove (1) along the length direction of the groove (1); after the use is finished, the operation of the electric drive module (60) is stopped, the pull rod (35) is vertically pulled upwards, the pull rod (35) drives the four sliding blocks (29) on the outer sides of the two side holding plates (A12) to synchronously vertically slide upwards through the two synchronous rods (32), each sliding block (29) drives the corresponding pawl (26) to rapidly separate from the corresponding ratchet wheel (25) through the corresponding rotating shaft (B27) and releases the rotation limitation on the ratchet wheel (25), the pawl (26) swings downwards around the corresponding rotating shaft (B27) for a small angle under the action of the corresponding two spiral springs (B28), and the two return springs (33) are further stretched; the four pawls (26) are kept in a separated state with corresponding ratchet wheels (25) respectively, the crank (A18) is rocked, the crank (A18) drives two side holding plates (A12) and two side holding plates (B19) at the lower end of the shell (8) to vertically and upwards perform reset motion through a series of transmission, the two side holding plates (B19) swing towards the outer sides of the corresponding side holding plates (A12) under the reset action of the corresponding two spiral springs (A24) respectively, and the two side holding plates (B19) drive the corresponding two ratchet wheels (25) to reversely rotate through corresponding rotating shafts (A22) respectively; as the two side holding plates (B19) are opened to both sides, the spool (78) is vertically separated downwards from the spool conveyor from between the two side holding plates (B19) and the two side holding plates (a 12); when the sliding column (7) is reset relative to the square sleeve (2), the acting force on the pull rod (35) is removed, the four sliding blocks (29) slide back and reset instantly under the reset action of the two reset springs (33), and the four sliding blocks (29) respectively drive the corresponding pawls (26) to be pressed on the corresponding ratchet wheels (25) again and meshed with the ratchet wheels (25) again.
