Propelling pencil

The invention relates to a mechanical pencil, comprising a body (2) which extends between a rear end and a front end (2a) and a lead feeding mechanism which comprises: a moving member (20), having a bearing surface (21a), a clamp (30), connected to the moving member, a clamping ring (18) which cooperates with the clamp head (32) and an elastic element (19), having a rear end (19b) which is supported on the bearing surface (21a). Said elastic element tensions the ring (18) against the head (32) when the feeding mechanism is at rest. A moving sleeve (40) is arranged between the clamping ring (40) and the front end (19a) of the elastic element. The clamp (30) is movable in relation to the moving member (20) along a determined stroke length. The body (2) has a stop (4b) for limiting the forward movement of the sleeve (40).
