The utility model discloses an optical anti-shake and anti-collision structure and an OIS motor. The optical anti-shake and anti-collision structure comprises a base; the flexible circuit board is fixed on the top surface of the base; the carrier is arranged at the top of the flexible circuit board; at least two first impact assemblies are uniformly arranged at the bottom of the carrier in the circumferential direction; the top of the carrier is evenly provided with at least two second impact assemblies in the circumferential direction. The carrier bracket is arranged on the outer side of the carrier in a sleeving manner; each side face of the carrier support is provided with at least one third impact assembly. The top of the carrier support is evenly provided with at least two fourth impact assemblies in the circumferential direction. And the outer frame is arranged on the base in a sleeving manner, and the flexible circuit board, the carrier and the carrier bracket are accommodated in the outer frame. According to the optical anti-shake and anti-collision structure provided by the utility model, the size of the impact table can be selected according to actual requirements by utilizing the cooperation of the detachable impact table and the impact groove, so that the impact range is adjustable, and different anti-shake strokes and focusing strokes can be met.

This utility model relates to a wear-resistant and quiet two-section hinge, comprising a first blade, a second blade, and a main shaft. The main shaft includes a male shaft and a female shaft. The male shaft is fixedly connected to the first blade, and the female shaft is fixedly connected to the second blade. One end of the female shaft has a blind hole, and one end of the male shaft has a convex shaft fixedly installed. The convex shaft rotatably engages with the blind hole. A wear-resistant sleeve made of polyetheretherketone (PEEK) is fixedly installed on the bottom inner wall of the blind hole. The top of the convex shaft fits against the wear-resistant sleeve. A polytetrafluoroethylene (PTFE) coating is fixedly installed at the opening end of the blind hole. A gap exists between the opposing surfaces of the male and female shafts. This design, through multiple improvements such as the inclusion of a PEEK wear-resistant sleeve, a PTFE coating, and a reasonable gap, solves the problems of high noise, easy wear, and poor applicability of traditional hinges, meeting the needs of hospitals, laboratories, data centers, and other application scenarios with high requirements for noise and cleanliness.

The present application relates to cold header technical field, specifically to a kind of high-speed cold header, including cold heading action component, fixed frame and moving frame, the moving frame is connected with external transmission component, multiple cold heading dies are fixedly installed in the fixed frame, multiple material ejecting components are fixedly installed in the side of the moving frame corresponding to cold heading die, the side of the fixed frame is fixedly installed with elastic air bag, the outside of the elastic air bag is fixedly installed with extrusion plate, the extrusion plate is slid on fixed frame by slide rod, gas pipe is installed through on the elastic air bag, by setting the material ejecting component that can be gas and simultaneously move, the gap between blank and cold heading die can be increased first, promote blank to first separate and the close connection between cold heading die, then it is ejected by the movement of ejector rod, make its friction with cold heading die reduce in the process of material removal, reduce the debris generated by blank under friction, and cooperate with continuous air and oil, let material removal be more smoothly.

The application discloses a driving motor, a camera module and an electronic device. The driving motor comprises a shell, a carrier, a driving assembly and an elastic assembly. The carrier is located in the shell and is used for carrying a lens. The driving assembly is connected with the shell and the carrier and is used for driving the carrier to move relative to the shell. The elastic assembly is connected with the shell and the carrier and is used for supporting the carrier. The elastic assembly comprises a waterproof layer and an elastic part, and the waterproof layer wraps the elastic part.

The utility model belongs to the related technical field of sewage treatment, specifically a kind of impurity collecting device of sewage filtration, including filter box, the water inlet is connected in the top of filter box;Servo motor is fixedly connected on the lateral wall of filter box;The output of servo motor is fixedly connected with round bar;Round bar is set as through and rotationally connected on filter box;The end of round bar is fixedly connected with filter plate;The end of filter plate is fixedly connected with intercepting plate;The inner wall of filter box is fixedly connected with baffle;A pair of pull rope is slidably connected in the inside of baffle;Sliding plate is slidably connected in the middle of filter box;A pair of top rod is fixedly connected in the middle of sliding plate;The fixed relationship of pull rope, sliding plate and filter plate is all fixedly connected;By increasing servo motor, filter plate can be quickly turned over reset, and baffle and top rod can quickly impact filter plate, so that the impurities intercepted on its surface are shaken off, thereby the impurities on the surface of filter plate are shaken off quickly, so as to drop to the bottom of filter box and be collected.

A laser generated plasma (LPP) light source includes a rotating target assembly (2) that supplies a target (3) together with a focused beam of high repetition frequency pulsed laser light into an interaction zone (4). The light source is efficiently cooled by thermal radiation of the peripheral portion of the rotating target assembly and by blowing gas through a serpentine gap (16) between the rotating target assembly (2) and the stationary heat exchanger (17). This achieves high brightness and high output power of the LPP light source.
