As shown in accompanying drawings 1 to 3, the utility model mainly includes a transmission shaft 1, an outer tube guide sleeve 2, a pulling shaft center 3, an inner tube guide sleeve 4, a propeller 5, and an outer sheath Tube 6, an adjusting nut 7 and an impedance head 8, wherein the transmission shaft 1 is placed in the guide sleeve 2 of the outer tube, and it is pivotally connected to the transmission mechanism 20, and the transmission mechanism 20 can be set as an electric impact electric drill, a battery type impact drill, etc. Screwdriver or pneumatic impact driver, the outer edge of the front end of the transmission shaft 1 is provided with a thread 11, the front end is hollow, and a hexagonal sleeve 12 is arranged on the inner edge of the hollow part;

The outer tube guide sleeve 2 is placed on the transmission mechanism 20, which is tubular, and the rear end is set to a larger diameter. A set of grooves 21 is provided at the end of the larger diameter for a spring 22 to be sleeved. The front end is provided with a free spring. Symmetrical guide grooves 23 with openings extending inward;

After pulling the shaft center 3 through a spring 31, put it into the guide sleeve 2 of the outer tube, the end of which is provided with a hexagonal fitting part 32 for fitting into the inner hexagonal sleeve groove 12 of the transmission shaft 1 or by The hexagonal sleeve 12 is automatically disengaged, and the front end is provided with a threaded portion 33;

The front end of the inner tube guide sleeve 4 is provided with a ring body 41 slightly larger than the outer tube guide sleeve, and a symmetrical anti-rotation blade tip 42 is arranged on the inner edge of the ring body 41, and the blade tip 42 is embedded in the outer tube guide sleeve 2 The guide groove 23, so that it can slide along the outer tube guide sleeve 2;
