The spring 94 is arranged in the slot. The short cylindrical roller 93 is arranged in the fixing groove. Both ends of the spring 94 are respectively connected to the short cylindrical roller 93 and the bottom wall of the slot.

[0054] Specifically, in this embodiment, its operating principle mainly depends on the movement of the short cylindrical roller 93 and the pressure of the spring 94, as well as the friction between the inner and outer rings 91. In normal operation, the short cylindrical roller 93 rubs against the outer ring 91 under the pressure of the spring 94, and is wedged between the outer ring 91 and the star 92, so that the power is transmitted to the star 92, driving the feeding. When the fast motor button is used, the star 92 obtains the same torque as the outer ring 91, and the speed is much faster. At this time, the friction between the short cylindrical roller 93 and the outer ring 91 and the star makes the short cylindrical roller 93 press the spring 94, and the short cylindrical roller 93 rolls toward the wide end of the wedge groove, thereby breaking the transmission connection between the outer ring 91 and the star 92, and realizing the overtaking.

[0055] Normal working mode: In normal working mode, the short cylindrical roller 93 rubs against the outer ring 91 under the pressure of the spring 94, and is wedged between the outer ring 91 and the star 92, so that the power can be transmitted to the star 92 to drive the feeding. In this state, the short cylindrical roller 93 maintains close contact with the inner and outer rings 91 through friction and the pressure of the spring 94, ensuring the effective transmission of power.

[0056] Fast feed mode: When using a fast motor, the speed of the star 92 is higher than the speed of the idler gear. At this time, the friction generated by the speed difference causes the short cylindrical roller 93 to compress the spring 94 and roll toward the wide end of the wedge groove, thereby disengaging the transmission connection between the outer ring 91 and the star 92. In this state, the short cylindrical roller 93 exceeds the clutch engagement point, realizing power transmission in the fast feed mode. The design of this clutch enables it to flexibly switch working modes under different speed conditions, providing stable power transmission in the normal working mode and achieving efficient kinetic energy conversion when fast feed is required.

Since the damper 15 limits the rotation of the driven gear shaft 14, the driven gear shaft 14, the inner ring of the one-way bearing 9, the load sprocket 10, the chain 11 and the carrier 12 remain stationary, thereby facilitating the pre-tightening device to pre-tighten the pipe clamp on the carrier 12 located at the pre-tightening station; the time length for the pre-tightening device to pre-tighten the pipe clamp on each carrier 12 is set to T2, and the running time of the intermittent mode is T2; Step (4), repeating steps (2) and (3), so that the pre-tightening device pre-tightens the pipe clamp on each carrier 12 in turn; Wherein, in the step (2), in the normal working mode, when the carrier 12 follows the chain 11 to move to the lower side of the load sprocket 10, the pipe clamp falls off from the carrier 12 and the unloading is completed.

[0059] The pipe clamp is transported from left to right and pre-tightened, and the material moves in the direction from the loading station to the pre-tightening station. The pre-tightening device is a device for screwing in the bolts and nuts of the locking part of the beer barrel clamp.
