when the cup rod 2 and the transmission rod 1 are in operation, after the joint of the cup rod 2 and the transmission rod 1 is covered by the second magnetic block 31, due to attraction of the second magnetic block 31 to the locking block 22, the locking block 22 moves towards the direction outside the movable groove 21 and is inserted into the locking groove 12 in the transmission rod 1, the cup rod 2 is further locked, connection failure of the cup rod 2 and the transmission rod 1 is avoided, meanwhile, in the rotating process of the cup rod 2, the locking block 22 is under the action of centrifugal force, it is guaranteed that in the operating process of equipment, the locking block 22 is always inserted into the locking groove 12, the reliability of connection between the cup rod 2 and the transmission rod 1 is guaranteed, the locking failure of the locking block 22 to the cup rod 2 in the rotating process is avoided, potential safety hazards are generated, and the phenomenon that the cup rod 2 and the transmission rod 1 are separated and fly out under extreme conditions is avoided.

In one embodiment of the present invention, the cross section of the locking block 22 is square; one end of the locking block 22 facing the outside of the movable groove 21 is oval;

in operation, because the cross-section of locking piece 22 is the square, insert locking groove 12 at locking piece 22 back, locking piece 22 is fixed relatively in the position in locking groove 12, effectively avoid locking piece 22 to appear removing in locking groove 12, lead to there being slight rocking between cup pole 2 and transfer line 1, after the spinning machine begins to operate, slight rocking between cup pole 2 and transfer line 1 is sharply enlargied under high-speed rotation, arouse cup pole 2 and transfer line 1 shake and junction damage, lead to the unable normal operating of spinning machine, and simultaneously, oval-shaped one end on the locking piece 22 can make locking piece 22 disregard the small skew between activity groove 21 and the locking groove 12, accomplish the process of inserting locking groove 12 smoothly.

As an embodiment of the present invention, the area near the bottom in the rotating cup 5 is uniformly provided with air vents 51; the positions, close to the upper end, on the cup rod 2 are uniformly provided with through holes 24; the through holes 24 correspond to the exhaust holes 51 one by one and are communicated with each other; the upper end of the outer side of the cup rod 2 is uniformly provided with blades 41; a reinforcing plate 4 is fixedly arranged on the outer side of the blade 41; when the cup rod 2 rotates, the blades 41 and the reinforcing plate 4 generate an effect similar to a fan blade; the outlet of the through hole 24 is located in the middle of the mounting area of the blade 41 and is surrounded by the reinforcing plate 4; the blade 41 is positioned above the first magnetic block 3 and is not in contact with the first magnetic block 3; the reinforcing plate 4 is positioned above the first magnetic block 3 and is not in contact with the first magnetic block 3; the blade 41 pushes the air flow to move upwards when the cup rod 2 rotates;

when the cup rod 2 rotates at a high speed, the blades 41 and the reinforcing plate 4 arranged on the cup rod 2 push air to flow, so that micro cotton wool and impurities discharged from the exhaust hole 51 of the rotary cup 5 are blown away upwards, the impurities are prevented from being deposited downwards between the magnetic block II 31 and the cup rod 2 and in a gap at the joint of the cup rod 2 and the transmission rod 1, the magnetic block II 31 is difficult to slide or is clamped on the cup rod 2, the magnetic block II 31 cannot move smoothly to a specified position to generate action, meanwhile, the impurities are prevented from being deposited in the gap at the joint of the transmission rod 1 and the cup rod 2, the connection between the cup rod 2 and the transmission rod 1 is not firm, safety accidents are found in subsequent operation, and meanwhile, the air flow speed at the outlet of the conducting hole 24 can be effectively accelerated through the blade structures formed by the blades 41 and the reinforcing plate 4, the pressure at the outlet of the through hole 24 is determined to be lower through the Bernoulli principle, therefore, under the action of atmospheric pressure and air flow passing through the outlet of the through hole 24 quickly, the air flow in the exhaust hole 51 communicated with the through hole 24 is drawn outwards, the outward exhaust speed of the rotor 5 and the negative pressure of the rotor 5 are increased, the tiny cotton wool and impurities in the exhaust hole 51 are conveniently discharged, the possibility of blockage of the exhaust hole 51 is reduced, meanwhile, the negative pressure in the rotor 5 is increased, the speed and the stability of the fibers entering the rotor 5 can be effectively improved, the yarn forming quality in the rotor 5 is improved, and the occurrence frequency of yarn breakage is reduced.

when the air flow pushing device works, the first distance is larger than the second distance through arrangement, the blades 41 rotate, and in the process of pushing the air flow to move upwards, because the gaps between the lower ends of the reinforcing plates 4 and the cup rods 2 are relatively small, when the blades 41 push the air flow to move, the pressure of the areas where the blades 41 are located is lower, the air volume extracted from the via holes 24 is added, the pressure in the via holes 24 and the air exhaust holes 51 is lower, the suction force is higher, the tiny cotton wool and impurities in the air exhaust holes 51 can be conveniently exhausted, the possibility of blocking of the air exhaust holes 51 is further reduced, the yarn forming quality in the rotating cup 5 is improved, and the occurrence frequency of broken ends of yarns is reduced.

The specific working process is as follows:

when the rotor 5 needs to be replaced or cleaned in operation, the motor which supplies power to the corresponding spinning device in the rotor spinning machine is turned off, then a worker grasps the rotor 5 and the cup rod 2 and forcibly lifts the rotor 5 and the cup rod 2 upwards to enable the upward acting force applied to the cup rod 2 to be larger than the magnetic attraction force between the convex block 25 and the mounting groove 11, and the rotor 5 and the cup rod 2 are taken down from the spinning device; after the change or cleaning of the rotating cup 5 is finished, the convex block 25 on the cup rod 2 is inserted into the mounting groove 11, and then the second magnetic block 31 which is slidably mounted on the cup rod 2 is pulled downwards, so that the second magnetic block 31 reaches the limit position and covers the position where the cup rod 2 and the transmission rod 1 are contacted with each other; after the second magnetic block 31 covers the joint of the cup rod 2 and the transmission rod 1, the second magnetic block 31 has attraction force on the locking block 22, and the locking block 22 moves towards the direction outside the movable groove 21 and is inserted into the locking groove 12 in the transmission rod 1; the blades 41 and the reinforcing plate 4 are mounted on the cup rod 2, and in the process of high-speed rotation of the cup rod 2, the blade structure formed by the blades 41 and the reinforcing plate 4 pushes air to flow, so that the air flow speed at the outlet of the through hole 24 is relatively accelerated, the pressure at the outlet of the through hole 24 is reduced, and the air flow in the through hole 24 and the air exhaust hole 51 is outwards extracted.
