Radial drilling machine facilitating rapid positioning

The radial drilling machine convenient to quickly position comprises a base and a placing plate, the placing plate is fixedly installed on the upper surface of the base, and rotating shafts are symmetrically and fixedly arranged in the placing plate. According to the radial drilling machine convenient to quickly position, a lead screw and a second motor are arranged, the second motor is started, the second motor drives the lead screw to rotate, the lead screw drives a supporting arm to move up and down, and the position of a movable block is changed, meanwhile, a gear, a first rack and a second rack are arranged, and the gear rotates to drive the first rack and the second rack to move, and a clamping block is pushed inwards; meanwhile, an air bag is arranged, after the planet carrier is machined, a second motor is started, the second motor drives a supporting arm to move upwards, the supporting arm extrudes the air bag, air in the air bag blows off chippings on the surfaces of a moving block and a placing pla
