Drilling device with drill jumping function for circuit board processing

The utility model discloses a circuit board processing drilling device with a drill jumping function, relates to the technical field of circuit board processing, and aims to solve the problems that when an existing circuit board is subjected to drilling processing, a drilling tool moves up and down, the drilling tool rubs against the circuit board, the circuit board is easy to move up and down, position deviation is caused, and the stability of drill jumping processing is influenced. A sliding rail is arranged at the upper end of the base, a supporting bottom plate is arranged at the upper end of the sliding rail, a moving frame is arranged above the supporting bottom plate, a mounting frame is arranged at the front end of the moving frame, a drilling tool motor is arranged at the front end of the mounting frame, and a circuit board is arranged at the upper end of the supporting bottom plate. The device further comprises four through slots which are formed in the upper surface of the supporting bottom plate a
