Abstract: The present disclosure discloses a lens driver, which applied to a photographic device. The photographic device includes a focal ring. The lens driver includes a first housing, a driving assembly, and a mounting member. The driving assembly is arranged on the first housing and is configured to adjust the focal ring. The mounting member is arranged on the first housing and is configured to install a battery. The battery is electrically connected to the driving assembly through the mounting member. In the present disclosure, the lens driver is provided with the mounting member for installing the battery, and the mounting member is capable of electrically conducting the battery and the driving assembly. When in use, it is only need to install the battery on the mounting member, which is more convenient.

Abstract: A stepless speed changer applied to a CVT gearbox is provided which comprises a speed changing mechanism, a clamping mechanism, and a speed regulating mechanism, and the speed changing mechanism is mounted on a shaft body and connected with a power input mechanism and a power output mechanism respectively along both sides of the shaft body; the clamping mechanism is distributed along an axial direction of the shaft body and located at both sides of the speed changing mechanism, and the clamping mechanism guarantees the speed changing mechanism transmits a torque normally by use of pressurization of a first hydraulic system; the speed regulating mechanism is located at a radial end of the shaft body and combined with the speed changing mechanism, and the speed regulating mechanism achieves speed change of the speed changing mechanism by use of acceleration and deceleration control of a second hydraulic system, which solves the structural problems of the existing CVT gearbox, for instance, low input torque, lim

Abstract: The present application relates to the field of electric vehicle connector, particularly to a new connector applied to USF cards and Micro SD cards. The connector comprises an end component, a frame and an outer shell. The end component is provided in the frame covered with the outer shell; UFS cards or Micro SD cards can be inserted into the frame and connected with the end component; the end component includes nineteen ends, i.e., Pin 1 to Pin 19; the ends of the inserted UFS card or Micro SD card can be connected with respective ends of the end component; the UFS card includes twelve ends(i.e., u1 to u12); the Micro SD card includes eight ends(i.e., m1 to m8).
