This utility model discloses a variable-angle aging board transport tool, including a support frame and a carrier structure disposed within the support frame. The carrier structure includes two limiting components arranged front to back. Each limiting component includes multiple limiting strips, a vertical fixed rod, a vertical movable rod, and a guide rod. The limiting strips are arranged vertically at intervals, forming a limiting groove between the upper and lower limiting strips. The two sides of the aging board are inserted into the limiting grooves at corresponding heights of the two limiting components and overlap with the limiting strips. One end of the limiting strip is hinged to the vertical fixed rod, and the other end of the limiting strip is hinged to the vertical movable rod. The vertical movable rod is connected to the guide rod and moves vertically along the length of the guide rod. The beneficial effect of this utility model is that by using the vertically movable rod to adjust the tilt angle of the limiting strips, the outer side of the limiting groove is higher than the inner side, which can effectively prevent the aging board from falling during transportation and solve the problem of aging boards easily falling and being damaged in the prior art.

The utility model discloses a self-locking type LED projection lamp angle adjusting mechanism, which belongs to the technical field of LED projection lamps, and comprises a U-shaped frame, an adjusting component is mounted in an inner cavity of the U-shaped frame, an angle adjusting component is mounted on the outer surface of the U-shaped frame, a sliding rod is driven to move downwards in a fixing sleeve by a hand of a user, a spring is compressed, and the angle adjusting component is mounted on the outer surface of the U-shaped frame. At the moment, the arc-shaped tooth block is separated from the gear ring and releases self-locking, the angle of the LED projection lamp can be adjusted at will, and on the contrary, the arc-shaped tooth block is meshed with the gear ring under the action of the spring, so that the LED projection lamp and the rotating rod are in a locked state and cannot rotate freely, and it is guaranteed that the LED projection lamp cannot deviate due to external force such as wind pressure and vibration after the angle is set. A user can quickly unlock only by dialing the hand dialing piece, the operation is simple and convenient, the response is quick, and additional tool assistance is not needed.
