The application provides a double-station worktable for CNC, and particularly relates to the technical field of CNC machine tool auxiliary equipment, and comprises a CNC main body, an inner platform and a tool head unit, and further comprises a double-shaft switching mechanism arranged between the outer side of the CNC main body and the inner platform, wherein the double-station worktable for CNC; the double-shaft switching mechanism composed of an X-axis displacement component, a Y-axis displacement component and a sinking fastening component is arranged, so as to solve the defects of the existing technology, such as the jamming misplacement caused by the single guide rail alignment of the multi-station switching, the lack of special connection structure, the non-separation of the carrier and the guide rail during the processing, the vibration transmission affecting the precision, and the like, to realize the cooperative action of the X-direction bearing movement of the jig table, the Y-direction smooth connection and the locking of the processing position sinking, and the double-station switching does not need complex debugging, so that the equipment downtime is greatly reduced, and the processing precision and stability are ensured.

This invention provides a pneumoperitoneum filter tube comprising a gas filter matched to the CO2 outlet of a pneumoperitoneum machine, a gas supply pipe, and a gas supply interface; the gas filter contains a filter membrane with an area not less than a certain value, the filter membrane having a pore size of 0.2-0.5 μm and an area of ​​25-35 cm². 2 The gas supply pipe has a diameter of 4-6mm and a length of 1.5-2.5m. One end of the gas supply pipe is sealed and connected to the gas filter, and the other end is equipped with a Luer male connector. It has good sealing performance, low resistance, is easy to use, low cost, and is provided aseptically. It is disposable to avoid cross-infection.

This application provides a sunshade and a vehicle. One end of the sunshade body is connected to a pull rod, and the other end is connected to a roller. One of the pull rod and the roller is connected to a window frame. The roller is used to wind the sunshade body in conjunction with a sunshade extension mechanism. A flexible light-emitting element is provided on the sunshade body to allow it to wind with the sunshade body. The flexible light-emitting element includes a bendable flexible substrate and a light-emitting material disposed on the flexible substrate. The flexible substrate is a film, or it can be woven or spun yarn. After covering the sunroof, this sunshade, through its flexible light-emitting structure, can create a starry sky effect inside the vehicle, solving the problem that traditional starry sky roof technologies cannot create a starry sky effect in the sunroof area, and addressing the difficulty of installing a starry sky roof on vehicles with panoramic sunroofs. Simultaneously, due to the flexible light-emitting structure, the sunshade can wind smoothly, avoiding any impact on the smoothness of the winding process.

The present application relates to a kind of precision guiding nest-preventing device and nest-preventing method integrated in sewing machine needle plate, the device is provided with fixed knife and movable knife on the lower surface of sewing machine large needle plate, the movable knife includes hooking part, dividing part, wire container groove and wire hole, cooperates with presser foot, blowing and suction pipe and connecting rod type driving mechanism, through the timing design of "stitching thread - guiding presser - stabilizing thread loop - cutting cleaning - resetting", realizes the precise guidance of thread end, cutting and cleaning.The device can reuse the built-in power of sewing machine, has compact structure and strong adaptability, can completely avoid the winding of starting thread, improve the quality and operation continuity of sewing product, and is suitable for all kinds of sewing machines such as lockstitch machine and pattern machine.

This invention discloses a urea filling pipe and a vehicle. The urea filling pipe includes a pipe body and a filter element. The pipe body has a fluid flow cavity and a filling port communicating with the fluid flow cavity. The filter element has a first state and a second state. In the first state, the circumferential edge of the filter element mates with the circumferential wall of the fluid flow cavity to filter the fluid flowing through the fluid flow cavity. In the second state, at least a portion of the outer periphery of the filter element is separated from the inner circumferential wall of the fluid flow cavity. The filter element is configured to switch between the first state and the second state. This invention can reduce the possibility of impurities entering the urea tank and thus contaminating it, and has little impact on the smoothness of the filling process.
