Described pen core tube 6 front ends arrange projection 4, and offer a breach on the tube wall of protruding 4 the same sides near lead for retractable pencil 1 place, and pen core tube 6 peripheries arrange spring 3, and spring 3 front ends prolong and form push rod 2.
Described pen core tube 6 interior lead for retractable pencils 1 are the trifle lead for retractable pencil of some band points.
Advantage of the present utility model: simple in structure, design science, pencil is when the state of use, push rod enters and withstands pencil-lead in the breach and can use, and thumb is pushed down the cap for brush when changing pencil-lead, and the descending protruding jack-up push rod of pen core tube withdraws from breach, the pen core of back is descending, then unclamps thumb, and pen core tube is replied under the elastic force effect, push rod reenters breach, withstands descending pencil-lead, and at this moment used pencil-lead is pressed from nib, it is in use convenient to realize, fast, manufacturing process is simple, and cost is low.
Description of drawings
Fig. 1 is a kind of extensible pencil structural representation of the utility model;
The specific embodiment
This a kind of extensible pencil comprises lead for retractable pencil 1, push rod 2, penholder 5, pen core tube 6 and the cap for brush 7, it is characterized in that: described lead for retractable pencil 1 is put into pen core tube 6, and pen core tube 6 is inserted in the penholder 5, and be inserted in the cap for brush 7 on the top of pen core tube 6.
Described pen core tube 6 front ends arrange projection 4, and offer a breach on the tube wall of protruding 4 the same sides near lead for retractable pencil 1 place, and pen core tube 6 peripheries arrange spring 3, and spring 3 front ends prolong and form push rod 2.
Described pen core tube 6 interior lead for retractable pencils 1 are the trifle lead for retractable pencil of some band points.
When pencil was the use state, push rod 2 entered in the breach, withstands pencil-lead, can use; When changing pencil-lead. thumb is pushed down the cap for brush 7, and pen core tube 6 is descending, and protruding jack-up push rod 2 withdraws from breach, the pen core of back is descending. and then unclamp thumb, pen core tube 6 is replied under the elastic force effect, and push rod 2 reenters breach, withstand descending pencil-lead, used pencil-lead is pressed from nib.
Meaning of the present utility model is that it is easy to use, saves trouble, and leaves a joint pencil-lead in the pen core tube and also can use, and manufacturing process is simple, and cost is low.
