Specifically, a clamping groove is formed in the inner ring at the center of the shuffling large disk, a convex rib is arranged on the outer wall of the inner gear ring, and the convex rib arranged on the inner gear ring is clamped into the clamping groove of the inner ring of the shuffling large disk.

Specifically, the planet wheel shaft and the poker bar are of an integrated structure.

Specifically, the upper part of the central shaft seat is provided with an external thread, and the upper part of the central shaft seat is in threaded connection with a nut cover for limiting the mahjong shifting bar between the external teeth of the central shaft seat and the nut cover.

Specifically, the bottom of the poker bar is provided with an annular bulge, and the bulge is abutted against the inner gear ring.

The utility model has the advantages of it is following:

1. the utility model discloses a design of tablet strip is dialled in differential rotation, forms planetary gear mechanism through the planet wheel that sets up on dialling the tablet strip and the outer tooth on the ring gear of inlaying and the central axis seat on shuffling the big dish together, utilizes the power when shuffling the rotation of big dish, and the drive silence is dialled the rotation of tablet strip syntropy differential.

2. The utility model discloses a group's tablet strip compares in the fixed tablet strip of dialling of tradition, and its relative speed with shuffling the big dish is little, so the relative speed when playing mahjong tiles that bear on shuffling the big dish and dialling the tablet strip and taking place the striking also can be littleer, just can reduce the noise when dialling the tablet, and need not shuffle the big dish rotational speed through reducing and realize this effect, just can not influence the speed of shuffling.

3. The mahjong shifting strip of the utility model can rotate all the time, and compared with the traditional fixed mahjong shifting strip, the mahjong shifting strip can not generate the situation that one end of mahjong is placed on the mahjong shifting strip, and the other end leans against the wall of the shuffling cylinder and does not participate in shuffling at last, thereby forming the 'shuffling dead point'.
