As shown in fig. 3, two first inner disk magnetic blocks 41, namely an S first inner disk magnetic block 41 and an N first inner disk magnetic block 41, are provided, and when the driving disk 9 rotates, the N pole of the first magnet 2 is attracted to the S first inner disk magnetic block 41, and when the driving disk 9 rotates, the S first inner disk magnetic block 41 will attract the N pole of the first magnet 2 to rotate, and the N first inner disk magnetic block 41 will also attract the S pole of the first magnet 2, under the action of such magnetic force, the first transmission shaft 4 will be driven to rotate, and the rotation angle and the fixed position of the driving disk 9 can control the rotation angle and the fixed position of the first transmission shaft 4. Because the first follower rod 5 is arranged on the first transmission shaft 4, the first roller 6 is arranged on the first follower rod 5, and therefore the rotation angle of the first transmission shaft 4 is the rolling radian of the first roller 6. When the first roller 6 rolls on the first slide way 3, the selective power of the first transmission shaft 4 cannot be transmitted outwards, when the first transmission shaft 4 drives the first roller 6 to roll on the first slide rail 8, the clamping mechanism on the first slide rail 8 is clamped with the first roller 6, the first roller 6 drives the whole clamping mechanism to slide along the first slide rail 8, and at the moment, the rotational power of the first transmission shaft 4 can be transmitted outwards. When the first roller 6 drives the clamping mechanism to slide to the tail end of the first sliding rail 8, the clamping mechanism can release the first roller 6, the first roller 6 rolls back to the first sliding rail 3, and power is not transmitted outwards any more.

The mode of the second transmission shaft 17, the second follow-up rod 18, the second roller 37, the second slideway 15, the second slideway 16 and the corresponding clamping mechanism for transmitting power outwards is the same as the structural principle of the first transmission shaft 4. Since the first transmission shaft 4 and the second transmission shaft 17 are coaxial, the first transmission shaft 4 and the second transmission shaft 17 are rotated in opposite directions when the driving disk 9 rotates. When the first roller 6 is rolled up in an arc shape, the second roller 37 is rolled down in an arc shape. When the first roller 6 is rolled arcuately downward, the second roller 37 is rolled arcuately upward. The first roller 6 and the second roller 37 are synchronously clamped with the corresponding clamping mechanisms, only when one transmits upward power, the other transmits downward power. So the yarn guide rod 35 and the tension rod 36 of the spinning machine can be respectively connected with the two clamping mechanisms, so that the yarn guide rod 35 and the tension rod 36 respectively realize lifting or pressing in different directions up and down, and then the spindle frame or the roving frame is moved. When the two clamping mechanisms do not transmit power to the outside, the magnetic assembly on the connecting shaft 28 and the outer ring magnetic block 12 are magnetically matched to control the connecting shaft 28 to rotate, so that the magnetic assembly of the connecting shaft 28 transmits signals to the outside to control the spindle frame or the roving frame to move.

In the absence of external force, the V-shaped rod 32 is balanced by the elastic forces of the upper tension spring 27 and the lower tension spring 33, and this state is a clamped state. When the clamping mechanism is located at the upper end of the first sliding rail 8, the adjusting part pushes the V-shaped rod 32 to rotate towards the upper end, and the upper catch wheels 23 of the two groups of clamping jaws are pushed to rotate towards the outer side and open, so that the first roller 6 can roll into a clamping space surrounded by the V-shaped rod 32, the upper catch wheels 23 and the lower catch wheels 22 of the two groups of clamping jaws. The first roller 6 needs to continue to rotate downwards under the drive of the first transmission shaft 4, the base 7 slides under the external force, the adjusting part no longer controls the V-shaped rod 32 to rotate, the V-shaped rod 32 keeps a clamping state under the action of the upper tensioning spring 27 and the lower tensioning spring 33, and the first roller 6 drives the base 7 to slide along the first sliding rail 8. When the first roller 6 drives the base 7 to slide to the lower end of the first slide rail 8, the adjusting part controls the V-shaped rod 32 to rotate towards the lower end, the lower catch wheels 22 of the two groups of clamping jaws are pushed to rotate towards the outer side and open, and therefore the first roller 6 can roll out of the clamping space and return to the first slide rail 3 from the lower side.

In the present embodiment, the operation mode of the locking mechanism on the first slide rail 8 will be described in detail, and the operation mode and principle of the locking mechanism on the second slide rail 16 are the same. In the absence of external force, the V-shaped rod 32 is balanced by the elastic forces of the upper tension spring 27 and the lower tension spring 33, and this state is a clamped state. The upper regulating wheel 25 is connected with the upper baffle wheel 23 by a rotating shaft passing through the upper arc chute 29, and the lower regulating wheel 24 is connected with the lower baffle wheel 22 by a rotating shaft passing through the lower arc chute 30. When the clamping mechanism is positioned at the upper end of the first sliding rail 8, the upper pushing jack contacts with the lower adjusting wheel 24, the lower adjusting wheel 24 is jacked, the V-shaped rod 32 is pushed to rotate towards the upper end, the upper catch wheels 23 of the two groups of clamping jaws are pushed to rotate towards the outer side and are opened, and therefore the first roller 6 can roll into a clamping space surrounded by the V-shaped rod 32, the upper catch wheels 23 and the lower catch wheels 22 of the two groups of clamping jaws. The first roller 6 needs to continue to rotate downwards under the drive of the first transmission shaft 4, under the action of the first roller 6, the base 7 overcomes the resistance of the upper push-up part 26 and slides along with the first roller 6, the upper push-up part 26 does not control the V-shaped rod 32 to rotate any more, the V-shaped rod 32 keeps a clamping state under the action of the upper tensioning spring 27 and the lower tensioning spring 33, and the first roller 6 drives the base 7 to slide along the first slide rail 8. When the first roller 6 drives the base 7 to slide to the lower end of the first sliding rail 8, the lower pushing piece 34 contacts with the upper adjusting wheel 25, the upper adjusting wheel 25 is pushed to move along the upper arc-shaped sliding groove 29, the V-shaped rod 32 is driven to rotate towards the lower end, the lower baffle wheels 22 of the two groups of clamping jaws are pushed to rotate towards the outer side and open, and therefore the first roller 6 can roll out of the clamping space and return to the first sliding rail 3 from the lower side.
