<p>The present invention discloses a rotatable lock catch and a grilling device with the rotatable lock catch, which solves the problem of how to lock the two joint semi-shafts rapidly. Said rotatable lock catch has a pin module and a rotary shaft joint with two semi-shafts; the upper half shaft of said rotary shaft has a post rod, the lower half shaft of said rotary shaft has a through hole for accommodating the passing in and out of said post rod; the upper end of a supporting shelf of said pin module is disposed with a U-shaped opening for adapting said rotary shaft, two short shafts are respectively disposed by the two sides of said U-shaped opening, two arc-shaped spacing flakes with opposite openings are respectively hinged joint with the corresponding short shafts; a movable ejector pin is disposed on the supporting shelf and along the midline of said U-shaped opening; a pressing board of the middle portion of said ejector pin upward presses the lower portions of the two spacing flakes; the upper portion of said ejector pin moves between the position of passing out of the U-shaped opening and the position of passing into the U-shaped opening to insert into said through hole of the lower half shaft, while the upper portions of the two spacing flakes correspondingly pass into the U-shaped opening for holding said rotary shaft or pass out of the U-shaped opening for releasing said rotary shaft. The rotary shaft will rotate after being held by the two spacing flakes, then the rotary shaft is locked and fixed; only after rotating and resetting the rotary shaft with the opposite direction, the upper half shaft will separate with the lower half shaft.</p> |
