Abstract

Mechanical pencil with two pressing ways, including a pen stick, a tip cover, a lead storage tube, an eraser seat, a pushing head, a pushing stick, a side pressing block, a lead spring, a connecting screw, a fixing nut, a clip and a locking ring. After being used, the pushing method is that the pushing head is pushed to drive the eraser seat, the lead storage tube, and the pushing stick to compress the lead spring, to push the three jaws of the clip, to release the three jaws from the locking ring, and to open the three jaws of the clip to le the lead drop freely to the movable damp. The pushing head is loosened again, the three jaws of the clip is retracted in the locking ring under the actuation of the lead spring to clamp the lead. The pushing head is pushed repeatedly to push out the lead in a pulsation way under the actuation of the movable damp, the connecting screw, the clip three-jaw structure and the locking ring. When being used, the operation of the side pushing method is that when lead is required to be added during writing, the side pushing block is pushed, the front end of the side pushing block is exerted on the sloping surface of the pushing stick, the pushing stick moves forward to push the three jaws of the clip, to push the lead out for a period distance in a pulsation way under the actuation of the movable damp, the connecting screw, the locking ring and the clip three-jaw structure to reaching the function of abrasion addition during writing.
