Abstract
A sight includes a main body, an erecting unit and a compensating mechanism. The compensating mechanism includes a fixing unit, a cover and an switching unit. A compensating mechanism for a sight includes a base unit, a transmission unit, an adjusting cap, a movable unit and a lock unit. The adjusting cap is located in a first position when the adjusting cap is locked by the lock unit. The adjusting cap in the first position can be rotated in a second direction or in a third direction opposite to the second direction when the lock unit is moved in a first direction to release the adjusting cap. The adjusting cap stops in a second position when the adjusting cap is rotated in the third direction so that the movable unit is propped against an end of a groove of the adjusting cap.

A compensating mechanism for a sight, comprising:
- a base unit;
- a transmission unit carried by the base unit;
- an adjusting cap connecting to the transmission unit and comprising a groove wherein the groove comprises a first end and a second end;
- a movable unit disposed between the transmission unit and the base unit and comprising a movable element;
- a lock unit movably disposed onto the adjusting cap,
- wherein when the adjusting cap is rotated, the movable unit is axially moved with respect to the base unit so that the movable element enters or leaves the groove;
- wherein the adjusting cap is located in a first position when the adjusting cap is locked by the lock unit;
- wherein the adjusting cap in the first position can be rotated in a second direction or in a third direction opposite to the second direction when the lock unit is moved in a first direction to release the adjusting cap;
- wherein the first end, the movable element and the second end are sequentially arranged along the groove, when the adjusting cap in the first position is released by the lock unit;
- wherein the adjusting cap stops in a second position when the adjusting cap is rotated in the third direction so that the movable element is propped against the second end of the groove.
