At this time, the knob body 57 cannot be pushed down as a whole, and if the knob body is pushed down and screwed, the rotating body member is rotated in the reverse direction to the locked direction, and the self-lock is released, and then the knob body is pushed down along the guide groove 55B by the guide pin 57B, and is disengaged from the main body 55 and screwed.

The tops of the knob body leg 57A and the connector leg 52A are both conical. The knob body leg 57A is prevented from abutting against the connector leg 52A when contacting with the connector leg, which affects the operation of the mechanism.

The handle part comprises a left clamping groove 58 and a right clamping groove 59, the left clamping groove 58 and the right clamping groove 59 face the side face of the button part and are provided with bulges at the upper edges, the left clamping groove 58 and the right clamping groove 59 are connected to the rotating body through screws 54, the left clamping groove 58 and the right clamping groove 59 are respectively arranged on two sides of the joint of the lower pressing area 57C and the return blocking area 57D, and a gap for clamping an external object is formed between the two sides and the return blocking area 57D.

After the press-down area 57C is pressed down, the chain can slide into the gap between the left and

right slots

58 and 59 and is blocked by the left and

right slots

58 and 59, and cannot slide in continuously, and after the press-down area 57C is reset, the fixed object cannot slide out any more due to the fact that the button returns to the blocking area 57D. The chain is a common structure in a machine for automatically playing the scroll, but the structure is adopted to realize the connecting function of the chain and the scroll, realize the multifunctional effect and be adopted for the first time.

Locking and unlocking indication marks can be arranged on the knob body 57, and a rotation direction use indication mark is arranged on the main body 55.

The lower case 53 is provided with a receiving cavity 53A protruding downward, and the receiving cavity 53A is used for receiving the connection body 52, so that it is more stable. The middle of the bottom surface of the lower shell 53 is provided with a through hole 53B, and the bottom of the connecting body 52 penetrates through the through hole 53B to be conveniently connected with the transmission piece 51. The lower case 53 is provided at the periphery thereof with fixing holes 53C for coupling with the body 55 by means of screws 54.

The whole working principle of the cycle transmission display machine is as follows:

the circulation display machine drives the middle movable cross beam 13 and the large chain wheel assembly 12 to move synchronously through the operation of the motor 16 and a belt or a chain. The operation of big sprocket assembly 12 drives the transmission of homonymy belt or chain, because two big sprocket assemblies 12 are synchronous operation, consequently, the little sprocket assembly 10 in both sides also is synchronous, syntropy operation, simultaneously, still has several kinds of functioning speed modes of quick, intermediate speed, low-speed to the operation of the show article that the realization hangs on the chain of both sides realizes two-sided bandwagon effect.
