Abstract
The utility model relates to a propelling pencil, solving the defect that the prior art has complicated structure and inconvenient use, and the lead cores are easy to break. The propelling pencil is characterized in that an ejector rod 7 and a groove 15 are arranged inside a column 8 arranged inside a shell 9 at the lower end; the ejector rod 7 is provided with threads, and is connected with a nut 6, wherein, the finishing end of the upper end of the nut is provided with inner threads; a plug 10 which is connected with the ejector rod 7 is arranged inside the groove 15. Thus, an eraser sleeve 13 is rotated to reveal a lead core 3 properly for use. With the advantages of convenient operation, and simple structure, the utility model can also cut the lead core, and the lead core is not easy to break. The utility model can also be used for plotting and writing.
Description
The utility model relates to a kind of pencil, the propelling pencil that particularly a kind of lead for retractable pencil can auto-feed.
Propelling pencil of the prior art is of all kinds in different poses and with different expressions, and their appearance people provide learning tool preferably.But its weak point is complex structure, and it is convenient inadequately to use, the lead for retractable pencil frangibility.
The purpose of this utility model is to solve above-mentioned weak point of the prior art, and provides a kind of easy to use, and lead for retractable pencil is frangibility not, the better simply propelling pencil of structure.
Technical solution of the present utility model is; The housing of propelling pencil is divided into upper and lower side 4,9, and lead for retractable pencil 3 places in the upper end 4, and the nut 6 with internal thread places the end of upper end 4.(or the terminal passage round mouth of placing lead for retractable pencil is shaped on screw thread in the upper end) termination, upper end is the claw flap type structure, and is spirally connected with end cap 1.Upper and lower side housing 5,9 is provided with push rod 7, groove 15 for being spirally connected in the cylinder 8 in lower end housing 9.Have screw thread on the push rod 7 and be connected with nut 6 that upper end 4 ends have an internal thread, the plug 10 that links to each other with push rod 7 places in the groove 15.The end of the cylinder 8 in the lower end housing 9 connects the erasing rubber 14 of a band erasing rubber cover 13.One pencil-knife 12 of cutting pen core is set on erasing rubber cover 13.The two ends of spring 11 are connected with the terminal inner surface of cylinder 8 in plug 10 and the lower end housing 9 respectively.In the termination of upper end 4, be provided with the soft holding sheet 2 of clamping lead for retractable pencil.Like this, this pencil is taken apart up and down, unscrewed the nut of claw flap type termination, lead for retractable pencil is sent in the upper end, then upper and lower side is spirally connected, the turn erasing rubber cover makes lead for retractable pencil be exposed to suitable length, tighten the claw flap type nut, take off erasing rubber cover, nib is fined away and can be used with the pencil-knife on it.As expose nib and use up, after end cap can being unscrewed, revolve erasing rubber again, make the lead for retractable pencil protruded length suitable, again end cap is tightened, nib is cut and can be used again.
The advantage that the utility model is had compared to existing technology is: lead for retractable pencil is frangibility not, and is easy to use, simple in structure.
