A circuit board hole inner wall
processing device comprises a bottom plate, an upper extending column is installed on the bottom plate through a screw, a penetrating column is arranged at the upper end of the upper extending column, a rotating transverse plate is rotationally arranged on the penetrating column, a
kidney-shaped hole is formed in the rotating transverse plate, the rotating transverse plate is sleeved with a sliding sleeve, an outer sleeve is arranged on the sliding sleeve in a penetrating mode, the outer sleeve is arranged in the
kidney-shaped hole in a penetrating mode, and an outer protruding edge is arranged at the lower end of the outer sleeve. The upper end of the outer sleeve is connected with a limiting nut, the outer sleeve is sleeved with a spring, an inner rod is arranged in the outer sleeve in a penetrating mode, the lower end of the inner rod is provided with a connector, the connector is provided with a cutter bar, a scraping blade is formed on the periphery of the lower end of the cutter bar, the connector is located at the lower end of the outer protruding edge, and a rotating
handle is arranged at the upper end of the inner rod. When stubborn glue blocks on the inner wall of the hole are removed, glue removing operation is rapidly completed by limiting the circuit board. And moreover, the axial
overlap ratio of parts such as a cutter bar and the like and the hole can be ensured, so that the cleaning speed and the cleaning effect of the rubber block are improved, and the inner wall of the hole can be obviously prevented from being scratched.
