Jade clamping device convenient to rotatably adjust

Abstract

The invention provides a jade clamping device that is easy to rotate and adjust, belonging to the field of jewelry processing, comprising a bottom box and a fixed clip frame; the front and rear ends of the left side plate of the bottom box are vertically fixed with support rods; the two A square block is fixed between the upper ends of the support rods; the middle of the square block is horizontally penetrated by a rotating shaft and is in a left-right direction; there are two fixed clip frames, which exist symmetrically on the left and right; the fixed clip frames are sandwiched between There is a movable clip frame and the movable clip frame exists symmetrically up and down; the two movable clip frames of the present invention are used to clamp the jade that needs to be processed; the rubber pad is used to prevent the movable clip frame from directly contacting and clamping the jade to cause breakage; when the jade needs to be clamped and placed , the upper and lower movable clamping frames are pulled open, causing the first spring to compress, and the jade is stuck between the two movable clamping frames. Under the action of the resilience of the first spring, the two movable clamping frames clamp the jade; There is a gap between the initial positions of the two movable clamping frames, which is convenient for the processor to separate the two movable clamping frames.
