The application provides a focusing motor and a camera module. The focusing motor comprises a fixed part, a moving part, a focusing assembly, a magnetic attraction sensing part, a guide part and a position sensor. The fixed part comprises a first support arm and a second support arm connected with each other, and a light passage hole formed between the first support arm and the second support arm. The moving part is arranged in the light passage hole and can move in a preset direction. The magnetic attraction sensing part is arranged in the moving part. The angle between the magnetization direction of the magnetic attraction sensing part and the first direction and the second direction perpendicular to the preset direction is an acute angle. The guide part is arranged on the first support arm and corresponds to the magnetic attraction sensing part. The position sensor is arranged on the second support arm and corresponds to the magnetic attraction sensing part. The position sensor can generate an induction force with the magnetic attraction sensing part, so that the position sensor can sense the moving position of the moving part. The focusing motor can significantly reduce the size of the focusing motor, and can guarantee the guiding stability and the position detection precision required by the automatic focusing function while realizing the miniaturization of the camera module.

This utility model relates to an online outer diameter measuring device, including a detection mounting base and an outer diameter measuring pen. Two material support frames are fixedly mounted on the detection mounting base, arranged along the length of the base, and each frame has a bearing groove adapted to the workpiece shape. A first guide rail is fixed on the detection mounting base between the two material support frames, and a second guide rail is slidably mounted on the first guide rail via a first slider. This utility model utilizes the V-shaped bearing grooves on the material support frames to adapt to the workpiece shape, combined with an anti-slip and wear-resistant pad adhered to the groove walls. Through the V-shaped positioning principle, the workpiece is stably supported. The anti-slip and wear-resistant pad increases the friction between the workpiece and the pad, effectively suppressing workpiece offset or tilting caused by placement deviation or rolling, ensuring that the workpiece axis remains consistent with the detection reference, and fundamentally reducing errors caused by detection position deviation.

This application relates to the field of fiber optic connector technology, and discloses a push-pull device for fiber optic connectors, comprising: a housing, which is drivenly connected to a ferrule; and a tail sleeve, which is connected to the housing via at least two cross-limiting structures, wherein the at least two cross-limiting structures are asymmetrically distributed in the vertical direction about the axis of the push-pull device; wherein, when the tail sleeve is pushed or pulled, the housing and the ferrule can move along the axis of the push-pull device. The asymmetrical cross-limiting structures can form staggered constraint forces in the radial and axial directions, effectively suppressing tilting or torsion of the housing and tail sleeve due to unilateral force. Furthermore, the asymmetrical distribution can disperse the push-pull force in different directions, avoiding stress concentration or local wear caused by symmetrical structures, reducing loosening or jamming caused by external forces or improper operation, and improving the stability and reliability of the connection between the tail sleeve and the housing. This application also discloses a fiber optic connector.
