[0003] For example, announcement number CN209997888U discloses a power-release chain, comprising a support rail, a drive chain, and multiple groups of unit conveying assemblies supported by the support rails. Each group of unit conveying assemblies is provided with a locking device that can be locked on the drive chain in a locked state, and is provided with an unlocking head for pushing open the locking device of the previous group of unit conveying assemblies when the spacing is not greater than a predetermined distance. The chain also includes a spare head, a pushing device, and an unlocking driving device for driving the spare head in and out of an unlocking path. The pushing device can drive the spare head after entering the unlocking path to move in the opposite direction along the drive chain, push the locking device to unlock, and continue to drive the spare head to drive the unit conveying assemblies to move in the opposite direction along the drive chain. This power-release chain can effectively solve the problem of inconvenience in stopping and repairing during the conveying process of the conveyed parts.

[0004] However, although this type of accumulation chain that can adjust the tension automatically can be used for daily use, it is not convenient to adjust the tension at different positions of the accumulation chain after long-term use, which makes it difficult to transport different objects too fast or too slow, affecting the stability of object transportation.

[0008] Furthermore, the threaded slider forms a sliding structure between the threaded rod and the fixed groove, and two groups of the fixed grooves are provided. The positions of the two groups of the fixed grooves are symmetrical with respect to the central axis of the threaded slider.

[0009] Furthermore, the regulating wheel is arranged on the rotation track of the conveying chain body.

[0010] Furthermore, the adjustment frame forms a telescopic structure between the swing rod, the limiting groove and the slide groove, and the slide groove is provided with two groups, and the position distribution of the two groups of slide grooves is symmetrical about the central axis of the adjustment frame.
