ABSTRACT:
This invention relates to a writing implement including an elongated tube having an upper open end and a lower end in which a clamping device and a propelling device are mounted, as well as a central bore extended from the upper open end to the clamping device. The central bore of the elongated tube includes an upper section as well as a lower section the diameter of which is smaller than that of the upper section. The lower section is provided with a plurality of radial grooves extended from the lower section for the purpose of receiving the leads. A lead supplying rod is rotatably fitted in the lower section of the central bore. The lead supplying rod has a through bore connected with the clamping device and a slot radially extended from the through bore thereof. The slot of the lead supplying rod communicates with one of the grooves of the tube and permits the leads to singly enter the through bore. Therefore, many leads can be received in the grooves of the tube and can respectively enter the through bore of the lead supplying rod via the slot of the lead supplying rod when the lead supplying rod is rotated to make the slot of the lead supplying rod respectively communicate with the grooves of the tube.
