Camera rotation device, monocular telescope, and rotation mechanism of monocular telescope

A camera rotation device, comprising:

• a carrier;
• a connection tube detachably assembled to the carrier and having a resistance portion formed on an outer surface thereof, wherein the outer surface of the connection tube is divided into a front segment and a rear segment through the resistance portion;
• a rotation annulus sleeved at the rear segment of the connection tube, wherein the rotation annulus has a plurality of teeth arranged on an outer side thereof and being in a ring-shaped arrangement;
• a resistance annulus sleeved at the front segment of the connection tube and fixed to the rotation annulus, wherein the rotation annulus, the resistance annulus, and the resistance portion jointly define an accommodating space;
• an oil film arranged in the accommodating space;
• and
• a driver assembled to the carrier to fix a relative position between the driver and the connection tube, wherein the driver includes a motor and a transmission mechanism that is engaged with at least one of the teeth;
• wherein, when the motor of the driver drives the transmission mechanism to push at least one of the teeth by receiving an electrical signal, the rotation annulus and the resistance annulus are rotated to move the camera device relative to the resistance portion for jointly implementing a rotation process, and synchronously generate a rotation resistance force in the rotation process through the oil film.

A rotation mechanism of a monocular telescope, comprising:

• a connection tube having a resistance portion formed on an outer surface thereof, wherein the outer surface of the connection tube is divided into a front segment and a rear segment through the resistance portion;
• a rotation annulus sleeved at the rear segment of the connection tube, wherein the rotation annulus has a plurality of teeth arranged on an outer side thereof and being in a ring-shaped arrangement;
• a resistance annulus sleeved at the front segment of the connection tube and fixed to the rotation annulus, wherein the rotation annulus, the resistance annulus, and the resistance portion jointly define an accommodating space;
• and
• an oil film arranged in the accommodating space;
• wherein, when at least one of the teeth of the rotation mechanism is pushed, the rotation annulus and the resistance annulus are rotated relative to the resistance portion for jointly implementing a rotation process, and synchronously generate a rotation resistance force in the rotation process through the oil film.
