[0011] Furthermore, a forward button and a reverse button are fixedly connected to the top of the fixed frame, and the forward button, the reverse button and the motor are electrically connected.

[0012] By adopting the above technical solution, it is convenient to control the forward and reverse rotation of the motor, thereby controlling the movable plate to enter and exit the fixed frame, and controlling the movable plate to move above the bed sheet, so that the cotton pad at the bottom of the movable plate wipes the bed sheet.

[0013] Furthermore, a cotton pad is fixedly connected to the bottom of the movable plate, and the bottom of the cotton pad is flush with the bottom of the fixed frame.

[0014] By adopting the above technical solution, when the movable plate moves, the cotton pad is driven to move, so that the cotton pad is wiped on the bed sheet, which is convenient for sampling.

[0015] Furthermore, a cavity matching with the rotating shaft is provided inside the fixing frame, and the cross section of the cavity is circular.
