Abstract
An anti-theft device secures a removable body part, such as a viewing unit, to a microscope stand. The device is intended to replace a common thumbscrew used to fix the location of a removable body part in a corresponding guide of the microscope stand, and comprises a housing threaded into a tapped hole in the stand for carrying a plunger and a driver both movable within an axial passageway in the housing. The driver is threadably adjustable by hand between driving and non-driving positions with respect to the plunger, and the plunger has a limited range of motion so that it may retract enough to allow the removable body part to be adjusted within the guide but not enough to allow the body part to be removed from the guide when the driver is in a non-driving position. The housing is tightened onto the microscope body by a tool such as a wrench, and the driver is held captive by a snap ring fitting within an internal groove near a trailing end of the housing.
