The purpose of this utility model provide a kind of lead for retractable pencil clamping safety firm, write pencil easily.

In order to realize the foregoing invention purpose, technical solution of the present utility model is:

A kind of Convenient pencil, mainly be to be made of penholder and lead for retractable pencil, its special feature is that penholder is separable two half, and wherein the head of half body of rod (1) inserts in the set groove that matches with it of half body of rod (2) head, after both merged, afterbody was pieced together the tight one that forms by the cap for brush (3).

The nib of half body of rod (2) lower end in the utility model technical solution shows taper, its center is provided with through hole, the table top on nib top extends upward half body of rod, table top has groove, body of rod afterbody is provided with a half-thread, and body of rod inboard has the matrix groove along its length and is embedded with antislip body (4).

In the utility model technical solution, half body of rod (1) adopts with half body of rod (2) and goes up the convex head that set groove matches, and afterbody is provided with one section half-thread, and medial surface is provided with groove along its length and is embedded with antislip body (4).

An end face of the cap for brush in the utility model (3) is embedded with rubber (6).

The technical solution of the utility model has adopted separable two and half body of rod combining structures, and lead for retractable pencil is changed and be flexible all comparatively convenient.The penholder internal cavities that next two and half body of rod described in the utility model combines is full of antislip body (4) along its length, therefore the lead for retractable pencil clamping is firm, and is stressed all around even, and do not have the moment of flexure effect, lead for retractable pencil is frangibility not, firmly writes or also unlikely when drawing it is pushed back in the penholder body.In addition, penholder described in the utility model is the same with common pencil, and the outside does not have any protrusion member, and the user holds and holds conveniently.
