The utility model is composed of a pencil point, a lead feeding clamping sleeve, a lead storing tube, a spinning wheel, a pencil holder, etc., wherein, a damping ring is arranged in the pencil point, and the pencil point is positioned at the cylindrical hollow front end of a small sharp sleeve, is tightly attached with a tube positive hole for avoiding inner broken of the small sharp sleeve, and is positioned in a taper sleeve; the taper sleeve is positioned at the back end of the small sharp sleeve, the front end of a locating sleeve is connected to the position in the back end of the small sharp sleeve, and the back end of the locating sleeve is connected with an inner tube; a spring is sheathed out of the inner tube, and the inner tube is connected with the spinning wheel. The utility model has the advantages that the use is convenient, the writing is fluent, the lead is not easy to be broken, the telescopic propelling pencil is convenient for carrying about, etc.
Description
The utility model has related to a kind of full automatic pencil, is specially adapted to the telescopic full automatic pencil that pencil-lead can carry out supply and clamping automatically.
Present existing full automatic pencil has automatic supply lead for retractable pencil continuous writing performance and advantage such as save time, but exists some defectives in actual use.As: Chinese patent 97242373.7 disclosed technology, its overall structure is using when closing, if carry, nib can scratch skin or clothes, and in carrying the device of lead for retractable pencil, cooperating between three-jaw chuck and the spring is perfect not to the utmost, come off easily, influence the clamping position that lead for retractable pencil enters nib like clockwork.
Main purpose of the present utility model provides one and has the automatic supply lead for retractable pencil continuous writing performance of reservation, fluent writing, and stroke is clear, and is easy to use, saves time, and is applicable to writing style and the telescopic full automatic pencil of being convenient to carry.
The purpose of this utility model realizes by following technical proposal: telescopic full automatic pencil of the present utility model, by nib, small apical sleeve, send plumbous chuck, interior pipe, core storage tube, spring spinning roller, penholder and turncap etc. to form; The metal penpoint that is built-in with damped ring is loaded on the front end of the garden post hollow of small apical sleeve, and be close to small apical sleeve and prevent interior disconnected normal pore of tube, with have the spring of certain-length to connect between the intermediate plate in the small apical sleeve, steel ball is equipped with in the intermediate plate both sides, be positioned at coning sleeve, coning sleeve is positioned at the rear end of small apical sleeve, it is characterized in that: connect in the front end of positioning sleeve and the small apical sleeve rear end, and the rear end of positioning sleeve connects with interior pipe, interior pipe is with spring outward and connects with spinning roller, rotation back cap connects with spinning roller, core storage tube passes spinning roller, rotation back cap, unsettled back with press head and connect, the said structure parts place sharp overlapping, center tap, penholder, back-up ring and block connect in the body that forms.
The utility model compared with prior art has easy to use, fluent writing, and not easily broken core also is convenient to carry etc., can not be stabbed advantages such as skin or clothing.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structure cutaway view of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in Figure 1, telescopic full automatic pencil of the present utility model is by nib 2, small apical sleeve 29, send plumbous chuck 26, interior pipe 11, core storage tube 20, spring 3 spinning rollers 19, penholder 22 and turncap 15 etc. to form; The metal penpoint 1 that is built-in with damped ring 2 is loaded on the front end of the garden post hollow of small apical sleeve 29, and be close to small apical sleeve 29 disconnected normal pore of tube in anti-, with the interior intermediate plate 4 of small apical sleeve 29 between have the spring 3 of certain-length to connect, steel ball 5 is equipped with in intermediate plate 4 both sides, be positioned at coning sleeve 6, coning sleeve 6 is positioned at the rear end of small apical sleeve 29, forms the lead for retractable pencil clamping and writes, loosens the routing motion that stretches out supply.Connect in the front end of positioning sleeve 28 and small apical sleeve 29 rear ends, make the accurate motive position that enters clamping, loosens of lead for retractable pencil.The rear end of positioning sleeve 28 connects with interior pipe 11, and interior pipe 11 is built-in with spring 8 and send plumbous chuck 26.Describedly send plumbous chuck 26 to be built-in with taper ring 27 and three-jaw chuck 25, be fixed on by bonnet ring washer 24 and send in the plumbous chuck 26, form and pinch the round composite resultant motion that lead for retractable pencil is fed forward.Round reciprocating cutter under the effect of spring, lead for retractable pencil is inserted through damped ring 1 and nib 2 from the clamp mouth part of intermediate plate 4, when lead for retractable pencil arrives the clamp mouth part of intermediate plate 4, intermediate plate can be clamped lead for retractable pencil, when lead for retractable pencil arrival nib 2 can be write, under the effect of spring, be in relaxation state between three-jaw chuck 25 and the taper ring 27, can not influence the performance of automatic supply lead for retractable pencil and continuous writing.Three-jaw chuck 25 afterbody cylinders pass bonnet ring washer 24 and connect with core storage tube 20, and spring 23 is housed between the connection.Interior pipe 11 is with spring 21 outward and connects with spinning roller 19, turncap 15 connects with spinning roller 19, core storage tube 20 passes spinning roller 19, rotation back cap 15, unsettled back and presses 16 and connects, and the said structure parts place in the body of point cover 30, center tap 10, penholder 22, back-up ring 31 and block connection formation.In the time will using, only need the turncap 15 of a rotation afterbody, pipe 11 formed whole stretching out forward with small apical sleeve 29 and arrives front end outside the point cover 30 in spinning roller 19 promptly drove under the positioning action of the positioning strip penholder 22 in 32, got final product the continuous writing use.At this moment, under the effect of spring 21 and positioning strip 32, the concave point place of spinning roller 19 and positioning strip 32 do not block and can break away from.When carrying, only need the turncap 15 of a rotation afterbody, the concave point place of spinning roller 19 and positioning strip 18 break away from, and under the effect of spring, pipe 11, small apical sleeve 29 retracted in the point cover 30 in spinning roller 19 drove.When if lead for retractable pencil produces interior disconnected phenomenon or need more renew lead for retractable pencil when writing, only need press connect with core storage tube 20 press 16, deposit lead for retractable pencil in the core storage tube 20 can be carried the split routing motion by the three-jaw chuck 25 and the clamping of taper ring 27, lead for retractable pencil is transported to metal penpoint position in the small apical sleeve 29, maybe will interrupt remaining lead for retractable pencil releases from metal penpoint, the nib of need not outwarding winding again point cover 30 connects with penholder, simultaneously because of having eliminated the deviation that produces when packing lead for retractable pencil into, just can not produce lead for retractable pencil yet and be stuck among the intermediate plate or stop up damped ring with hand.
