Examples
Referring to fig. 1-3, a rotary mechanism suitable for a sample dispenser according to the present utility model is disclosed.
The rotating structure frame 1 of the integral device is square, the upper part of the rotating structure frame 1 is connected with the gear set fixing plate 2 through bolts, and the gear set fixing plate 2 is smaller than the frame plane. The middle part of the rotating frame 1 is connected with a driving motor 9 through a bolt, and a proper motor is selected according to the required power for use. A reducer fixing plate 6 is connected to the lower part of the rotating frame 1 by bolts.
The output shaft of the driving motor 9 is connected with a speed reducer 8, so that the rotation speed output by the driving motor 9 is reduced, and the torque is increased.
The output shaft of the speed reducer 8 is connected with a lower driving block 7, the other end of the lower driving block 7 is connected with a connecting rod 3, and the other end of the connecting rod 3 is connected with an upper driving block 10.

Because the driving gear 14 is bigger, a bearing cushion block 12 is additionally arranged above the driving bearing and is connected with the gear set fixing plate 2, so that the driving gear 14 is positioned lower, and the driving gear 14 and the driven gear 15 are conveniently and perfectly meshed.
The driven shaft 4 and the driven gear 15 are connected in a key way or welded according to the requirement, and the driven shaft 4 is provided with a fixed support nut 5 which is connected with a fixed support, so that the mechanism is stable during operation.
The working principle of the utility model is as follows:
during normal operation, the driving motor 9 is used for reducing the rotating speed and increasing the torque through the speed reducer 8, the speed reducer drives the lower driving block 7 to rotate, the lower driving block 7 drives the upper driving block 10 to rotate through the connecting rod 3, the rotating directions of the upper driving block and the lower driving block are opposite, the lower driving block 7 continuously rotates clockwise, the moving direction of the connecting rod 3 is changed from bottom to top to bottom after one cycle of the lower driving block, the upper driving block 10 connected with the connecting rod 3 circularly rotates according to 180-degree cycles clockwise and anticlockwise, the upper driving block 10 drives the driving shaft 11 to rotate, the driving gear 10 drives the driven gear 15 to rotate through gear tooth meshing rotation, and the driven shaft 4 connected with the driven gear 15 is driven to rotate, and automatic steering of the sample preparation device connected with the driven shaft 4 is realized due to the periodical change of steering of the upper driving block 10.
