Abstract: A tape measure includes a case, a measuring tape, and a snap-fit assembly. An opening is arranged on the case. The measuring tape is capable of be pulled out of the case or retract into the case through the opening. A first fastener is fixedly connected to a second end of the measuring tape. The first fastener is capable of selectively and magnetically engage with one of second fasteners. The first fastener and the second fasteners limit the position of the first fastener on the case through a limiting structure. The snap-fit assembly is capable of reduce the occurrence of accidental detachment of the first fastener from the case.

Abstract: Disclosed is a camera apparatus for medical detection, including: a shell, a circuit board arranged in the shell, and a data cable and a detection sensor which are electrically connected to the circuit board. A probe is arranged on an outer side of the shell, the probe is electrically connected to the circuit board, and an adapting piece is sleeved on an outer side of the probe. The detection sensor is configured to detect whether the adapting piece is mounted at a set position of the probe or not. The circuit board controls a working state of the probe according to the detection result of the detection sensor.

Abstract: Disclosed is a telescopic rod endoscope, including a shaping pipe, wherein one end of the shaping pipe is fixedly connected to one end of a telescopic pipe; a camera is mounted at the other end of the shaping pipe; the other end of the telescopic pipe is fixedly connected to a guide pipe; a connecting line is sleeved between inner cavities of the guide pipe and the telescopic pipe; and one end of the connecting line penetrates through the shaping pipe and is electrically connected to the camera, and the other end of the connecting line penetrates through the guide pipe and is connected to an external interface. Through extension and contraction of the telescopic pipe, the telescopic pipe facilitates observation of high and distant targets when being extended, and the shaping pipe is convenient for the camera to make small directional changes, thereby facilitating observation.
