[0016] Working process of the present invention:

[0017] In the working process of the yarn twisting scaffold of the present invention, the crank 228 is pulled to drive the turntable 227 to rotate clockwise, the turntable 227 drives the screw body 221 to rotate and move backward, the screw body 221 drives the annular seat 226 to move backward through the connecting body 225, the annular seat 226 pulls the traction rope 224 through the movable pulley 223, the traction rope 224 pulls the driving mechanism 236 to move downward, the driving mechanism 236 drives the two seats 235 to move toward each other and move downward at the same time (while the driving mechanism 236 moves downward, the rack 2362 drives the gear 2363 to rotate, and the gear 2363 drives the constant force spring 2365 to bend and elastically deform through the transmission shaft 2364), thereby realizing the adjustment of the outer diameter becoming smaller.

[0018] Pulling the crank 228 drives the turntable 227 to rotate counterclockwise, and the turntable 227 drives the screw body 221 to rotate and move forward. The screw body 221 drives the annular seat 226 to move forward through the connecting body 225, and the annular seat 226 drives the movable pulley 223 to move forward. At this time, the traction rope 224 is relaxed, and the driving mechanism 236 drives the two seat bodies 235 to move in the opposite direction and move upward at the same time (because the driving mechanism 236 is not pulled by the traction rope 224, the transmission shaft 2364 drives the gear 2363 to rotate under the action of the constant force spring 2365, and the gear 2363 drives the two racks 2362 to move in the opposite direction, thereby driving the two seat bodies 235 to move in the opposite direction), thereby realizing the adjustment of the outer diameter enlargement.

[0019] Since the outer diameter can be adjusted to be smaller, it is convenient to take the yarn. During adjustment, the two lower supports 231 and the two upper supports 232 change the inclination at the same time, so the adjustment speed is fast.

[0020] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
