Abstract
The present invention relates to an adjusting structure for a limit switch. The adjusting structure comprises a base, a worm gear shaft, an elastic positioning plate, a limit cam and an upper cover. The adjusting structure has a shaft holder on the center, an action trench on one side, and a shaft bracket formed on the other side for holding the worm gear shaft. The worm gear shaft comprises a spindle and a worm gear. The worm gear has a plurality of brake trenches on the outer surface. The elastic positioning plate mounted in the base is designed for touching the brake trenches of the worm gear so as to fix the worm gear shaft after the rotation of the worm gear shaft. The worm gear is partially projected to the outside of the base. The limit cam is fixedly coupled with the shaft holder. The limit cam has a limit control plate extending from the other side. The limit control plate is projected into the action trench. Accordingly, the limit switch can be adjusted easily without the use of any tool to detach or screw the components.
