The utility model relates to a knife sharpening technical field, and disclose an automatic knife sharpening device, including the knife rest of installation for the knife edge part of cutting knife is used to the knife sharpening assembly of grinding, the knife sharpening assembly includes the electromagnet and the knife sharpening stone of knife rest installation through the knife sharpening support, the knife sharpening stone is opposite with the knife edge part of cutting knife and is adjusted the interval of both through the electromagnet, the utility model discloses the interval of the knife sharpening stone and cutting knife is adjusted through the electromagnet, when electrifying, electromagnet core drives push rod and makes the knife sharpening stone close to the knife edge, after power off, reset under the spring action, need not stop the machine to complete grinding, can greatly shorten the knife sharpening time to improve equipment utilization and processing efficiency, and then improve actual capacity, also avoid the body injury and the dust inhalation etc. safety hidden danger brought by manual stop operation simultaneously.

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.
