The present application provides a display device, including: a display configured to display a user interface including view display areas and a focus object, wherein each view display area includes one or more items; a memory configured to store computer instructions; and a processor configured to execute computer instructions to cause the display device to perform operations. The operations include: displaying the user interface on the display; receiving a user input for moving the focus object; and moving a target item to a position where the focus object is; where in response to a number of the one or more items in the view display area being greater than a maximum number of items displayable on a screen of the display, the one or more items are displayed in a fixed focus cycling mode; and otherwise, the one or more items are displayed in a fixed focus non-cycling mode.

Method for displaying user interface and display device

A shearer cutting unit with double-speed rollers includes a motor driving unit, a motor driving unit, a gear transmission unit and a roller output unit. The motor driving unit includes a left cutting motor and a right cutting motor which are both arranged in a cutting unit case and connected with the roller output unit in a transmission way through the gear transmission unit. The roller output unit comprises a middle output shaft (-), a far-end output shaft, a middle support frame, a middle roller, a far-end support frame and a far-end roller. A cutting roller is separated into two coaxially-rotating parts, and the two rollers can rotate in different speeds.

Shearer cutting unit with double-speed rollers

Provided is a hand brake limiting device, comprising a bearing I (), a spring, a spring holder (), a guide plate (), and a guide plate holder (); the bearing I () is disposed on the spring holder (); the spring is sleeved on the outside of the bearing I (); the guide plate () and the guide plate holder () are sequentially disposed at one side of the spring away from the spring holder (); a stopper post III () is secured to one side of the spring holder () facing the spring; a stopper post In () is secured to one side of the guide plate () facing the spring; a stopper post II () is secured to one side of the guide plate holder () facing the guide plate ().

Hand brake limiting device

Provided is a hand brake, comprising a hand wheel (), a chain (), an enclosure (), a drive shaft assembly () which is disposed in the enclosure (), bull gear (), and base assembly; the hand wheel () is connected to the drive shaft assembly (), one end of the chain () is fixed to the bull gear () by means of rivets, and the main shaft of the bull gear () is a chain winding shaft (). The hand brake further comprises a limiting device disposed on the chain winding shaft () between the bull gear () and the base (); the limiting device comprises a first bearing (), a torsion spring (), a guide plate (), and a guide plate holder (). Installing the hand brake not only prevents the problem of the chain interfering with the movable pulley when the hand brake is deployed and thus affecting the performance of the hand brake, but also provides for a better appearance.

Hand brake
