The invention discloses a storage cabinet with a lifting type blade door. The storage cabinet comprises a cabinet body and the cabinet door arranged on the cabinet body. The cabinet door comprises a lifting type blade mechanism which comprises a plurality of cabinet door blades and a cabinet door lifting frame. The cabinet door blades are arranged on the cabinet door lifting frame. The storage cabinet further comprises a motor transmission device. When the cabinet door is opened, the cabinet door lifting frame is folded and ascends, the cabinet door blades are driven to turn over to be folded, and the cabinet door is opened upwards. When the cabinet door is closed, the cabinet door lifting frame is unfolded to descend, the cabinet door blades are driven to turn over to be unfolded, and the cabinet door is closed downwards. The cabinet door of the storage cabinet with the lifting type blade door can be fully opened, objects can be placed and taken conveniently, and when the cabinet door is opened and closed, indoor effective use space is not influenced, and the cabinet door is tight and safe when closed. The cabinet door can be opened or closed with little force, operation is convenient, the service life is long, manufacturing cost is low, and good stability is achieved.

The invention discloses a small paper tailoring device used for printing. The small paper tailoring device used for printing comprises a base, a lifting paper pressing device and a tailoring device; a guiding rule slide rail is arranged on one edge of the upper surface of the base, and is provided with a movable guiding rule; the lifting paper pressing device and the tailoring device are arranged on the upper surface of the base, and the arrangement positions of the lifting paper pressing device and the tailoring device are parallel to the arrangement position of the movable guiding rule; the lifting paper pressing device is located between the movable guiding rule and the tailoring device; and the tailoring device comprises an installing base, a transmission beam, a guiding slide rail and a too bit. The small paper tailoring device used for printing is reasonable in structural design, the lifting paper pressing device, the tailoring device and the base are designed in a combined manner, the structure of the device is made miniaturized, use is convenient, and the design of the added movable guiding rule can facilitate alignment of tailored paper; and due to the combined design that three tools of a straight line knife, a curved line knife and an imaginary line knife are adopted at the same time, the requirements of various tailoring styles of a user can be met conveniently.

Heat radiation module comprises a first housing, a second housing, a heat conducting structure and several pieces of porous structure. Shape of the first housing is corresponding to shape of the second housing. The second housing possesses an aperture. The heat conducting structure is jointed to the aperture of the second housing. Thus, the first housing, the second housing and the heat conducting structure constitute a closed structure. The said several pieces of porous structure are formed on inner wall of the closed structure.

The invention discloses a digital controlled lathe for processing a piston with a non-circular section, and the body of the digital controlled lathe is in an inverted T-shaped structure, namely the body thereof is in a horizontal non-circular piston digital controlled lathe structure in which the principal shaft of a workpiece is horizontally rearmounted, and a left knife rest and a right knife rest are arranged on the front side, thus not only facilitating processing of the piston with the non-circular section and but also having the function of processing the circular section. Non-circular turning is realized by adopting a bilayer dual-drive structure, a linear electric motor is adopted for driving at an upper layer so as to realize feed motion of high-speed non-circular section turningwith small displacement, a servo motor and a ball screw nut mechanism are adopted for adjusting the changed diameter of the processed piston at a lower layer, and the rough machining and finishing machining are integrated into a whole so as to enable the piston processing mode to be more reasonable, convenient and efficient.
