Abstract
The utility model discloses a drilling sharpening type propelling pencil and a matched drilling sharpener. As a locking device (4) is installed on the tail end of a pencil body (1), a lead can not be shifted or rotated when a user writes characters or sharpens a pencil in a drilling way; a matched drilling sharpener for the lead sharpens the lead, and then, the user can write freely; the thickness of the lead is more than 1.4 mm, the lead is not easily broken, and raw materials are saved.
Description
The utility model relates to a kind of drilling formula propelling pencil and supporting drilling device, belongs to the stationery class.
Existing propelling pencil, lead for retractable pencil only are 0.5～0.7mm, therefore very easily fracture, and write picture not freely; Common pencil child is difficult for drilling, and pencil-knife is not durable, and waste is big; And higher hand, the electronic pencil sharpener of price carries and inconvenience.That CN2292675Y discloses is a kind of " thick core propelling pencil ", and it is by the shaft of a writing brush and be enclosed within taper on the shaft of a writing brush and cut cover and form with the conehead screw rod that nib fuses.The conehead screw rod can be locked lead for retractable pencil in conjunction with tapered sleeve, and lead for retractable pencil is taken out of.Take off taper on the shaft of a writing brush and cut and be enclosed within nib and go up turn, lead for retractable pencil can be whittled into taper.It is easy to use, fast, especially be useful for the students of the junior years and engineers and technicians.But its structure relative complex, difficulty of processing is big, and does not belong to and go out lead for retractable pencil automatically.
Task of the present utility model is to overcome the deficiencies in the prior art, and a kind of drilling formula propelling pencil and supporting drilling device thereof are provided, and makes it to be applicable to the above lead bullion core of 1.4mm, frangibility not, with the supporting drilling device nib of just fining away, write with facility, easy to operate.
Above-mentioned task is achieved in that drilling formula propelling pencil and supporting drilling device, comprise that handwriting, nib, a tail advance button, spring, pen core tube, lead for retractable pencil chuck and lead for retractable pencil, there is a type conical bench lead for retractable pencil chuck upper end, the corresponding band concave cone with the pen core tube lower end of this end platform inwall sticks with glue and connects, spring housing is at lead for retractable pencil chuck middle part, lead for retractable pencil chuck lower end and damper cap matched in clearance, nib advances button to be respectively with pen core tube with locking device, a tail and is threaded with handwriting, handwriting tail end.With the matching used drilling device of drilling formula propelling pencil, have on its housing and the identical conical bore of nib, connect blade at the tail end of conical bore with screw, blade only can become coniform with the lead for retractable pencil drilling.
Drilling formula propelling pencil and supporting drilling device are skillfully constructed, and modern design is used the above lead bullion core of 1.4mm specially, is furnished with special drilling device drilling pen core, writes with facility, and frangibility is not good and cheap, saves material again.
Below in conjunction with accompanying drawing an embodiment of the present utility model is described in further detail
Fig. 1 is the structural representation of drilling formula propelling pencil
Fig. 2 is the structural representation of supporting drilling device
Drilling formula propelling pencil and supporting drilling device, comprise that handwriting 1, nib 2, a tail advance button 3, spring 5, pen core tube 6, lead for retractable pencil chuck 7 and lead for retractable pencil 9, there is a type conical bench lead for retractable pencil chuck 7 upper ends, the corresponding band concave cone with pen core tube 6 lower ends of this end platform inwall sticks with glue and connects, spring 5 is enclosed within lead for retractable pencil chuck 7 middle parts, lead for retractable pencil chuck lower end and copper damper cap 8 matched in clearance, nib 2 advances button 3 to be respectively with pen core tube 6 with locking device 4, a tail and is threaded with handwriting 1, handwriting 1 tail end.When lead for retractable pencil 9 is installed, can pushes a tail downwards and advance button 3, promotion pen core tube 6, lead for retractable pencil chuck 7 move down, and directly insert from written 2 holes; Also can screw off nib 2, push a tail downwards and advance button 3, lead for retractable pencil 9 is inserted from lead for retractable pencil chuck 7 ends, unclamp a tail and advance button 3, lead for retractable pencil has just clamped, and this moment is rotating locking apparatus 4 again, makes it to push against a tail button 3, lead for retractable pencil just can not produce displacement or rotation in handwriting, just can be with supporting drilling device drilling tip of a pencil.Because lead for retractable pencil is locked, guarantee that lead for retractable pencil can not produce displacement lead for retractable pencil chuck 4 in when writing, firmly excessive, tip of a pencil can be broken for maximum, and pencil-lead 9 phenomenon that in handwriting 1, contracts can not occur.With the matching used drilling device of drilling formula propelling pencil, the conical bore identical with nib arranged on its housing 10, use screw 11 to connect blades 12 at the tail end of conical bore, after 4 lockings of pencil-lead 9 usefulness locking devices, can in lead for retractable pencil chuck 7, not rotate during drilling yet.Because the conical bore on the drilling device is identical with written 2 taperings, and nib is inserted, the pencil-lead that only exposes could contact with blade, and the rotation handwriting just can become coniform with the lead for retractable pencil drilling.
