The rotating cylinder 105 is provided with a plurality of chip racks 106 to increase the number of chips filled. After the chips in one chip rack 106 are used up, the driving member 108 drives the rotating cylinder 105 to rotate, thereby driving the chip rack 106 to rotate, so that another chip rack 106 moves to the top, and then the chips in another chip rack 106 can be used. It can be understood that the aforementioned scheme can be used to increase the number of chips filled, and can also be used to drive the rotating shaft 104 to rotate.

[0023] According to this specific embodiment, the supporting legs 102 are installed on the housing 101 . There are four supporting legs 102 , which are respectively located at four corners of the bottom of the housing 101 . The housing 101 is supported by the four supporting legs 102 .

When the chips inside one of the chip racks 106 are used up, the pushing member 110 is reset, and the driving member 108 is started, thereby driving the rotating shaft 104 to rotate, and the rotating shaft 104 drives the rotating sleeve to rotate, and then drives the chip rack 106 to rotate, so that another chip rack 106 loaded with chips is rotated to the top and aligned with the opening on the limiting sleeve 107.
