A four color multi-pencil capable of one-handed operation is presented. Each color is contained in a cartridge assembly and each cartridge assembly may be individually selected for use and the material within the cartridge advanced for dispensing by means of a single pressing motion. The multi-pencil is designed to be a snap together assembly. No fasteners or adhesives are required. The multi-pencil contains a main body and a barrel. Housed within the barrel are a plurality of cartridge assemblies. Housed within the main body are a plurality of slide members for actuating the cartridges. Each cartridge assembly contains a mechanism for advancing drawing material or material to be dispensed, which is operated by simply depressing a cartridge selector.

A mechanical pencil includes a clamping claw for playing a coordination role in lead output. An abutting member is arranged in front of the clamping claw. The rear end, corresponding to the clamping claw, of the abutting member is provided with an abutting portion. The abutting portion includes a first through hole allowing a lead to move through. The abutting portion can be inserted into the clamping claw in a case where the clamping claw moves forward and simultaneously drives the clamping claw to open outwardly. The mechanical pencil has a better lead output effect.

A mechanical pencil according to an embodiment includes a barrel; a chuck mechanism that is housed inside the barrel and is capable of chucking and feeding out a writing lead for a mechanical pencil; and first and second cushion springs that elastically support the chuck mechanism in an axial direction with respect to the barrel, wherein a first cushioning region having a first spring constant and a second cushioning region having a second spring constant are formed by combining the first and second cushion springs, and the first and second cushioning regions are connected with no skipping.

A mechanical pencil including: a body cylinder; a lead releasing unit configured to release a writing lead and having a rear region supported inside the body cylinder such that a front region thereof is flexurally deformable or tiltable inside the body cylinder; and a stretchable elastic body arranged between the lead releasing unit and a body cylinder, in which the lead releasing unit has a pressed portion on an outer circumferential surface of the front region, the body cylinder has a pressing portion in a front region, the pressing portion and the pressed portion abut on each other before the front region of the lead releasing unit is flexurally deformed or tilted, and the pressing portion causes the pressed portion to relatively move to the rear side with respect to the body cylinder when the front region of the lead releasing unit is flexurally deformed or tilted.
