Description

TECHNICAL FIELD [0001] The present invention relates to a safety device for a tripod simplex shoe for an optical device,

The present invention relates to a safeguard apparatus for a tripod quick shoe for an optical instrument, and more precisely, a plate mounted on an optical instrument is inserted into a clamp, and in a state without arbitrary operation, a plate mounted on an optical instrument is prevented from falling out of the clamp, This is a safety device for the quick shoe that enables protection.

In most clamping devices used for optical instruments, if the plate is not fastened with a fastener after inserting the plate, the effect of the safety device can be seen only if there is a slight clearance even if the safety device is constituted. And the plate is released from the clamp. Further, the safety device installed in the clamp, which is used by inserting a cylindrical plate into a conventional cylindrical clamp, is inconvenient to use, And it is structured so that it can not escape from the frame of the safety device which is fastened by using the quick lever, and it is a reality that it can not satisfy the desire of people using the optical device.
