Laser therapeutic instrument for paronychia and onychomycosis

The invention discloses a laser therapeutic instrument for paronychia and onychomycosis. The laser therapeutic instrument comprises a box body, supporting legs, a rubber sheet, a wrist table, a fingertable, a partition plate, a fixing rod, a fixing plate, limiting rods, a spring, a gear, a laser pen, a connecting rod, a supporting rod, a control rod, a friction rod, a semiconductor chilling plateand a drying box. The instrument is simple in structure and convenient to operate, by pinching the tops of the two limiting rods and moving the two limiting rods up and down, the limiting teeth at the bottoms of the limiting rods can be easily and rapidly clamped into or separated from the gear, and fingers with different diameters can be fixed through the fixing plate; under the action of structures such as the connecting rod, the position of the lower end of a laser pen can be changed by moving the control rod up and down, so that the position of laser can be changed according to the position of nails, positioning i
