Abstract:
1. A paint can-clamping device applicable to a double-gyroscopic mixer, comprising a lower supporting plate, left and right guide rails fixed on the lower supporting plate, and an upper pressing plate mounted on the left and right guide rails via a locking mechanism and being movable up and down along the guide rails, wherein the locking mechanism comprises an upper pressing plate-fixing frame, locking pieces, and a locking piece spring; the locking pieces are located in the upper pressing plate-fixing frame, a front end of each of the locking pieces is in contact cooperation with the corresponding guide rail and has an arc surface, a rotary shaft passes through and is mounted in the front end of each of the locking pieces, the arc surface of the front end of each of the locking pieces is eccentric with respect to the rotary shaft at the front end of the locking piece such that the arc surface of the front end of the locking piece is rotatable eccentrically about the rotary shaft at the front end of the locking piece; and the locking pieces each are in friction cooperation with a V-shaped groove in the respective guide rails, and wherein the upper pressing plate is connected to the upper pressing plate-fixing frame via a guide pole, such that the upper pressing plate is movable linearly with respect to the upper pressing plate-fixing frame along an axis direction of the guide pole; a cam structure having a cam handle is mounted in the upper pressing plate-fixing frame, and the cam structure is cooperated, via a cam pressing mechanism for pressing the locking pieces downwardly, with the locking piece, such that the locking pieces move away from the V-shaped grooves of the guide rails to be in unlocking state, thereby achieving a linear movement of the upper pressing plate along the guide rails.
