Cam lock mechanism

The utility model relates to a cam lock mechanism. Cam lock mechanism has elasticity and parallel relative the setting including activity piece, stay and cam, movable piece and stay, and movable pieceincludes stay contact site and stay supporting part including activity piece contact site and activity piece supporting part, stay, and the cam rotationally sets up between movable piece contact siteand stay contact site, and the activity piece lies in near slider one side, and activity piece and stay pass through the rotation extrusion of cam, and the realization is to the locking of slider. The utility model discloses a cam lock mechanism, cam not with slider direct contact, through realizing the locking to the slider with the cooperation of activity piece and stay, cam and activity pieceand stay complex required precision are less than the cam directly and slider complex required precision, have simplified cam lock mechanism's machining precision, have reduced the processing degree of difficulty. 本实用新型涉及种凸轮锁紧机
