The invention discloses a clamping and fixing device for electronic product processing. The clamping and fixing device for the electronic product processing comprises a U-shaped plate, wherein the upper surface of the inner wall of the U-shaped plate is fixedly connected with the upper surface of an upper clamping plate. A first non-slip mat is fixedly connected with the lower surface of the upperclamping plate. The right side surface of the upper clamping plate is fixedly connected with the left side surface of a fixed block. The upper surface of the fixed block is fixedly connected with theupper surface of the inner wall of the U-shaped plate. A groove is formed in the lower surface of the fixed block, wherein the upper surface of the inner wall of the groove is fixedly connected withthe top end of a connecting rod through a limiting device. According to the clamping and fixing device for the electronic product processing, through the combined action of a handle, a second rotary shaft, a second bevel gear, a first bevel gear, a first rotary shaft, a thread column, a thread cylinder, the upper clamping plate and a lower clamping plate, clamping force of the upper clamping plateand the lower clamping plate on electronic products is convenient for staff to adjust, and thus good fixing action on the electronic products to be processed can be greatly achieved, and the electronic products to be processed cannot be damaged.
