The tension structure is used for connecting a drive part with a rotating part. The tension structure is able to drive the rotating part to rotate about a rotation axis under a driving of the drive part, and the tension structure includes: a first connection part, in transmission connection with the drive part; a limit part, including a bottom wall and a side wall arranged at a periphery of the bottom wall, in which the side wall defines therein installation slots; and the bottom wall is detachably connected to the first connection part to enable the side wall to sleeve outside the first connection part; and tension parts, engaged with the installation slots, respectively. A side of each of the tension parts facing away from the first connection part protrudes from a corresponding installation slot and presses against the rotating part.

Tension structure and drum motor

The multi-frequency antenna transmission, including a drive gear, a gear train with parallel gear shafts, screw assemblies and a shifter. The transmission gears are connected to the stoppers of the screw assemblies one by one, the drive gear drives the various transmission gears to rotate, and all the stoppers rotate. The shifter pushes the stopper of one of the screw assemblies, such that the first elastic member disposed between the connection member and the stopper is compressed, and the connection member is connected to corresponding lead screw, thus the power of the stopper is transmitted to corresponding lead screw through the compressed first elastic member and the connection member, and drives the lead screw to rotate.

Multi-frequency antenna transmission

A multiband antenna transmission, including: a driving gear, a shifter, and a plurality of screw assemblies. The position and the driving gear are coaxially and rotatably arranged, and the shifter comprises a plate and a boss protruding from a side of the plate. The plurality of screw assemblies are arranged in a circumferential direction of the driving gear. Each of the plurality of screw assemblies includes: a lead screw, a driven gear selectively connected with or separated from the lead screw, and a first elastic member arranged between the lead screw and the driven gear. The boss is configured to sequentially push the driven gear of the respective screw assembly during rotation of the shifter, such that the driven gear is connected with the corresponding lead screw and whereby the driven gear is in mesh with the driving gear for transmission.

Multiband antenna transmission device

A camera extending and retracting device, including: a support base configured to be mounted inside a housing of a mobile phone; a screw movably arranged on the support base; a drive unit in connection with one end of the screw; a nut arranged on the screw; a push block mounted on the nut and configured to connect with the camera module of the mobile phone. The other end of the screw is provided with a load bearing mechanism configured to bear an axial force of the screw, and the load bearing mechanism is mounted on the support base. A mobile phone, includes: a housing, a camera module arranged in the housing, and a display screen arranged on the housing, and the above camera extending and retracting device.
