Digital intra-oral imaging device

A digital intra-oral imaging device comprises a hollow front part body and a rear part body connected to the front part body. The front part body has an opening defined in the front portion thereof and a circular recess defined in and around the internal circumference wall of the rear portion thereof. A reflector and a light emitting device are disposed above the opening inside the front portion. The rear part body consists of a front tube body and a rear tube body each having a through hole. An elastic latch is inserted in the front and rear tube bodies and has two latch hooks extending through the through holes respectively. The latch hook that is extended from the front tube body is then wedged in the circular recess of the front part body, thereby detachably and rotatably connecting the front part body and the rear part body.
