A top frame 27 is obliquely connected between the end of the ear seat 30 and the end of the tightening column 22. The tightening column 22 can drive the top frame 27 to move to push the ear seat 30, so that the rubber twisting ears 24 on the two ear seats 30 can move toward each other, so that the rubber twisting ears 24 can still hold the surface of the wire harness after wear. The opposite ends of the two ear seats 30 are connected to the rubber twisting ears 24, and a driving member is installed on the platform of the bundle twisting machine body 1, and the driving member is connected to the twisting sleeve 14.

[0025] A notch is provided in the middle of one of the rubber twisting ears 24, and the other rubber twisting ear 24 corresponds to the notch, so that when the rubber twisting ear 24 is pushed and tightly hugged to the surface of the wire harness after being worn, the two rubber twisting ears 24 will not hinder each other. A sleeve seat 12 is coaxially mounted on the outer surface of the twisting sleeve 14 near the middle, and the end of the sleeve seat 12 is fixed to the twisting frame of the bundle twisting machine body 1, and the sleeve seat 12 plays a role in supporting the twisting sleeve 14. A guide sleeve 13 is fitted on the outer surface of the tightening column 22, and the guide sleeve 13 plays a role in guiding the tightening column 22, and the end of the guide sleeve 13 is fixed to the twisting sleeve 14.

[0026] A tightening spring 21 is wound around the outer side of the tightening column 22, and the tightening spring 21 plays a role in pushing the tightening column 22. A top cap 26 is coaxially inlaid on the outer surface of the tightening column 22 near one side edge, and the top cap 26 plays a role in being pushed by the tightening spring 21.

The No. 2 connecting shaft 29 serves to facilitate the connection of the top frame 27. The end of the ear seat 30 is embedded in the outer surface of the No. 2 connecting shaft 29.

[0028] The opposite surfaces of the two ear seats 30 are each provided with a No. 1 splicing interface 32, and the middle parts of the opposite surfaces of the two rubber twisted ears 24 are extended with a connecting column 33, and the end of the connecting column 33 is provided with a No. 2 splicing interface 34. The arrangement of the No. 1 splicing interface 32 and the No. 2 splicing interface 34 can ensure that the ear seat 30 and the connecting column 33 are firmly fixed when spliced ​​together, and the No. 1 splicing interface 32 on the ear seat 30 is engaged with the No. 2 splicing interface 34 on the connecting column 33. The outer surface of the ear seat 30 and the outer surface of the connecting column 33 are screwed with a threaded ring 31, and the threaded ring 31 serves to lock the ear seat 30 and the connecting column 33 together. A plurality of rotating columns 35 are extended in an annular array on the outer surface of the threaded ring 31, and the rotating columns 35 serve to facilitate the rotation of the threaded ring 31.

[0029] The driving component includes a gear ring 2 installed on the platform of the bundle twisting machine body 1. The center line of the gear ring 2 is colinear with the rotation center line of the twisting frame of the bundle twisting machine body 1. A gear 20 is meshed with the upper part of the gear ring 2. The cooperation between the gear ring 2 and the gear 20 can drive the rotating rod 19 to rotate by itself when the twisting frame of the bundle twisting machine body 1 rotates. The rotating rod 19 is embedded in the middle part of the gear 20. A transmission rod 6 is connected to the top of the rotating rod 19. The transmission rod 6 plays a transmission role. One end of the transmission rod 6 is connected to the twisting sleeve 14.

[0030] A rod frame 15 is rotatably installed on the end of the rotating rod 19, and the end of the rod frame 15 is fixed to the twisting frame of the bundle twisting machine body 1. The rod frame 15 plays a role in supporting the rotating rod 19 and the transmission rod 6. The transmission rod 6 is rotatably installed on the rod frame 15. The other end of the transmission rod 6 is coaxially inlaid with a No. 2 small pulley 16. The No. 2 small pulley 16 and the No. 2 large pulley 18 play a role in accelerating the transmission. The outer surface of the rotating rod 19 is coaxially inlaid with a No. 2 large pulley 18. A No. 2 synchronous belt 17 is connected between the No. 2 small pulley 16 and the No. 2 large pulley 18. The No. 2 synchronous belt 17 plays a role in connecting the rotating rod 19 and the transmission rod 6 together.

[0031] One end of the transmission rod 6 is coaxially inlaid with a large pulley 7, and a small pulley 11 is coaxially inlaid on the outer surface edge of the twisting sleeve 14. A synchronous belt 10 is connected between the small pulley 11 and the large pulley 7. The small pulley 11 and the large pulley 7 play the role of accelerating the transmission. A through groove 9 is opened through the middle of the twisting frame of the bundle twisting machine body 1. The synchronous belt 10 plays the role of connecting the transmission rod 6 and the twisting sleeve 14 together. The synchronous belt 10 passes through the inside of the through groove 9, and the gear 20 rotates synchronously with the twisting frame and rolls on the gear ring 2 to drive the rotating rod 19 to rotate, so that the rotating rod 19 passes through the large pulley 18 and the small pulley 16 to drive the transmission rod 6 to rotate faster, and then the transmission rod 6 passes through the large pulley 7. The No. 1 small pulley 11 drives the rubber twisting ear 24 on the twisting sleeve 14 to accelerate rotation, so as to increase the twisting force of the rubber twisting ear 24 on the wire harness. The outer surface of the transmission rod 6 is coaxially rotatably installed with a rod seat 8, and the rod seat 8 serves to bear the transmission rod 6. The rod seat 8 is fixed to the twisting frame of the bundle twisting machine body 1. Two ring ears 3 extend symmetrically inside the gear ring 2, and a ring bracket 5 is fixedly installed at the end of the ring ear 3. The ring ear 3 and the ring bracket 5 serve to support and fix the gear ring 2. The end of the ring bracket 5 is fixed to the platform of the bundle twisting machine body 1, and the side of the ring bracket 5 is obliquely fixedly installed with a reinforcement frame 4. The reinforcement frame 4 serves to increase the bearing capacity of the ring bracket 5, and the end of the reinforcement frame 4 is fixed to the platform of the bundle twisting machine body 1.

[0032] During twisting, the twisting frame on the bundle twisting machine body 1 rotates to drive the wire harness to be twisted. In this process, the gear 20 rotates synchronously with the twisting frame and rolls on the gear ring 2 to drive the rotating rod 19 to rotate, so that the rotating rod 19 drives the transmission rod 6 to rotate faster through the second large pulley 18 and the second small pulley 16, and then the transmission rod 6 drives the twisting sleeve 14 to rotate faster through the first large pulley 7 and the first small pulley 11, so that the rubber twisting ear 24 on the twisting sleeve 14 can hold the surface of the wire harness and rotate, so as to twist the multiple wire harnesses again, so as to strengthen the twisting strength of the wire harness. The multiple wiring harnesses are tightly combined, and under the action of the tightening spring 21, the tightening column 22 can be pushed, thereby driving the lifting frame 27 to move, so as to push the ear seat 30, so that the rubber twisted ears 24 on the two ear seats 30 can move toward each other, so that the rubber twisted ears 24 can still hold the surface of the wiring harness after wear. If the rubber twisted ears 24 are excessively worn, the threaded ring 31 can be completely rotated onto the ear seat 30 to separate the mutually engaged ear seat 30 and the connecting column 33, that is, the rubber twisted ears 24 can be removed from the ear seat 30 for replacement, and then can continue to be used.
