Specifically, in order to realize the above-mentioned automatic page turning function, the driving mechanism in this embodiment is composed of a stepping motor 40, a lead screw 41, a polished rod 43, and the like, and in order to enhance the stability of the mechanism, a first fixing frame 11 is fixedly added at the top inside the outer casing 1, and a second fixing frame 12 is fixedly added at the bottom inside the outer casing 1. Wherein the stepping motor 40 is arranged at the top position in the outer shell 1, and the stepping motor 40 is fixed on the first fixed rack 11 in a threaded manner; the upper end of the screw rod 41 is in a stepped shaft shape and is connected with the output end of the stepping motor 40 through a coupler, the lower end of the screw rod 41 is in a stepped shaft shape and is rotationally connected with the second fixed rack 12 through a bearing, and the lower end of the screw rod 41 is also integrally and coaxially provided with a driving gear 42, namely the screw rod 41 is actually a gear shaft; the upper end of the polished rod 43 is in a stepped shaft shape and is rotationally connected with the first fixed rack 11 through a bearing, the lower end of the polished rod 43 is in a stepped shaft shape and is rotationally connected with the second fixed rack 12 through a bearing, a driven gear 44 is further arranged at the lower end of the polished rod 43, a flange coupler 440 is further sleeved on the outer side of the lower end of the polished rod 43, and the driven gear 44 is fixedly connected with the flange coupler 440 in a threaded mode; it should be pointed out that can guarantee through flange shaft coupling 440 that driven gear 44 can not take place axial displacement when rotating, flange shaft coupling 440 upper end spiro union is on driven gear 44 spoke during concrete installation to through screw and polished rod 43 locking, thereby prevent driven gear 44's axial displacement, adopt flange shaft coupling 440 to make this structure lighter and more stable. In addition, the driven gear 44 is meshed with the driving gear 42, and the transmission ratio after meshing is 2: 1, i.e. when the driving gear 42 rotates one revolution, the driven gear 44 follows one half revolution. Meanwhile, the linkage mechanism is assembled on the screw rod 41 in a threaded manner, the polished rod 43 is sleeved with the gap, and the page turning mechanism is clamped on the polished rod 43 in a sliding manner and limited by the linkage mechanism. When the page turning work is carried out, the lead screw 41 and the driving gear 42 can be driven to rotate through the operation of the stepping motor 40, then the driving gear 42 drives the driven gear 44 and the polished rod 43 to rotate, the page turning mechanism is further driven to rotate to complete page turning, meanwhile, the lead screw 41 drives the linkage mechanism matched with the lead screw to move up and down when rotating, and then the page turning mechanism is driven to move up and down on the polished rod 43 through the limit of the linkage mechanism on the page turning mechanism to complete transposition, so that the functions of automatic page turning and transposition are realized.

In order to prevent the page turning mechanism from being interfered by the clamping member 3 during turning at every time, and no matter which side the page turning mechanism turns the page, the corresponding clamping member 3 can be driven, and the page turning mechanism is designed in the embodiment: the two ends of the page turning slider 60 are both provided with pushing and abutting columns 601, the clamping member 3 is specifically divided into an abutting portion 30 close to the page turning mechanism and a clamping portion 31 far away from the page turning mechanism, the abutting portion 30 is provided with an upward first baffle 301 and a downward second baffle 302, taking the clamping member 3 on the right side as an example, referring to fig. 10-14, the first baffle 301 is arranged on the front side, and the second baffle 302 is arranged on the rear side. And a gap channel 3001 penetrating up and down is formed between the first baffle plate 301 and the second baffle plate 302, and the width of the gap channel 3001 is adapted to the diameter of the pushing column 601 so as to facilitate the pushing column 601 to slide up and down therein. In addition, the first baffle 301 is upward, which means that the top end is higher than the second baffle 302, and the second baffle 302 is downward, that is, the bottom end is lower than the first baffle 301, and the specific height is designed according to the size of the pushing column 60 which can just separate from the clearance channel 3001 when the clamping member 3 turns the page to the right.

Thus, the page is turned from right to left according to the requirement, and the state process is circularly repeated to sequentially bring the clamping piece 3 on the right side to the left side.

Vice versa, when the pages are turned from left to right, the page turning slider 60 rotates a certain angle (12 degrees in this embodiment) first until the pushing and supporting column 601 at the left end just contacts the second baffle 302, the pushing and supporting column 601 can push the inner wall of the second baffle 302 during the continuous rotation process so that the clamping member 3 slides along the guide ring 2 to complete the page turning, and meanwhile, the pushing and supporting column 601 can slide from bottom to top in the clearance channel 3001 along with the driving of the page turning slider 60, and the pushing and supporting column 601 also stops rotating and can just separate from the second baffle 302 and the clearance channel 3001 until the page turning is in place, that is, when the clamping member 3 reaches the right limit; and at this time, the transposition is successful, and the state refers to the state in the process. Therefore, the page is turned from left to right according to the requirement, and the clamping pieces 3 on the left side can be brought back to the right side in sequence by circularly repeating the state process.

In the design, the state that the pushing column 601 stops is designed to be just tightly attached to the upper end of the inner wall of the first baffle plate 301, so that the traditional page turning requirement is met, the page turning time can be saved by the design because most people can turn pages from right to left when turning pages, and the page turning can be realized quickly just by rotating.
