The invention discloses a direction adjusting mechanism for mold printing. The direction adjusting mechanism comprises a pair of frame supports. Each frame support comprises an upper mounting seat and a lower mounting seat, vertical guide rail seats are fixed between the upper mounting seat and an outer end portion of the lower mounting seat, vertical sliding seats are slidingly arranged on the vertical guide rail seats, mold head support seats are disposed in frame supports, cross guide rail seats are fixed on the vertical sliding seats, cross sliding seats slidingly matched with the cross guide rail seats are fixed on the mold head support seats, and hand wheels for pushing the vertical sliding seats to move vertically are rotatably arranged on the upper mounting seat. Sliding table cylinders for achieving stretching or releasing of a mold head and dial plate hand wheels for pushing a mold head support to move horizontally in order to achieve accurate positioning of the mold head are arranged on the vertical sliding seats. Through the hand wheels and the dial plate hand wheels, manual horizontal adjustment function and manual vertical adjustment function of the mold head can be achieved, adjustment precision is improved, stretching and loosing functions of the mold can be achieved by the aid of the sliding table cylinders, and the direction adjusting mechanism for mold printing is simple in structure and convenient and flexible to operate.

The invention relates to a hydraulically-driven steering device, in particular to an electrically-controlled hydraulically-driven steering device for a mobile platform of an agricultural robot, which comprises a supporting plate, a double-acting single-piston-rod cylinder, a connecting rod, a hydraulic steering gear, a coupler, a stepping motor, an oil tank, a remote controller, a three-position four-way electromagnetic directional valve, a gerotor motor, a filter, a gasoline engine, a dual gear pump, a speed regulating valve and a one-way valve. The stepping motor is connected to a power input shaft of the steering gear through the coupler, the steering gear is a parallel four-rod steering gear, and the remote controller is used for controlling steering and turn angles of the stepping motor to change the expansion length of a piston rod, so that turn directions and the turn angles of wheels are controlled. The remote controller is used for adjusting the position of a valve spool of the three-position four-way electromagnetic directional valve to control steering of the hydraulic motor, so that advancing, retreating and stopping of a four-wheeled vehicle are realized. The speed regulating valve is added in front of the stepping motor so that stepless speed regulating can be realized, and the electrically-controlled hydraulically-driven steering device is simple in structure, convenient in operation and low in cost.

Embodiments of the present invention provide a scene switching method and a head-mounted electronic device. The method includes: receiving a first input from a user to a target object in an AR picture displayed on a virtual screen; In the target area of ​​the AR screen, display N identifiers, where N is an integer greater than or equal to 1; receive a second input from the user on the target identifier in the N identifiers; in response to the second input, display the target Identifies the corresponding target VR picture; wherein, the N identifiers are used to indicate information matching with the target object. In this way, the user can input the target object in the AR screen to trigger the device to display a logo indicating the object related to the target object, and then can trigger the device to display the corresponding VR screen by re-entering the target logo to realize AR The switching between the scene and the VR scene does not need to rely on other physical devices during the switching process, and the operation mode is convenient and flexible.
