Mounting clamp for optically coated cambered umbrella stand

The invention provides a mounting clamp for an optically coated cambered umbrella stand and belongs to the field of optical processing equipment. The mounting clamp comprises a base, a sliding plate,a positioning plate and a lifting rod. The sliding plate is slidably mounted on the base and can slide horizontally along the base; the positioning plate is provided with a first end and a second end,the first end is hinged to the lifting rod, and the lifting rod is vertically fixed to the sliding plate; a telescopic rod is also fixed to the sliding plate, and the top end of the telescopic rod can move freely and can be in contact with the second end. The optically coated cambered surface of an umbrella is trepanned. The inclination angle of the positioning plate is adjusted according to thelifting rod and the telescopic rod, and the relative position of the positioning plate is adjusted through the sliding plate, so that an arc-shaped positioning block needs not to be manufactured, andthe mounting clamp can be us
