Further, the design that the front portion of the pen rod is circular and the back portion of the pen rod is square enables the pen not to fall down easily.
Description
Technical field
The utility model relates to a kind of mechanical pencil, belongs to a kind of stationery.
Background technology
Pen is seen everywhere in daily life, and a kind of stationery is absolutely necessary.General pen is furnished with cap, can write, but cap does not connect the shaft of a writing brush, easily loses after while writing, cap being taken off; Also the mechanical pencil that has built-in spring, presses button and can eject and regain nib, but these two kinds of pens all can not automatic drawing back when not using nib or entangle nib protected.Cover cap or forget that button regains nib nib is exposed to outer in the situation that forgetting, pen drops to the ground and easily causes nib damage, can not write, and the pen core that need to more renew, has caused waste; Pen is arbitrarily placed and nib is exposed to when outer, the ink of nib also can be stained with because of carelessness with it or other article such as clothes on, clean trouble.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provide a kind of structural design more rationally, nib can automatic drawing back, mechanical pencil easy to use.
The technical scheme in the invention for solving the above technical problem is: this mechanical pencil comprises penholder and penholder protecgulum, described penholder protecgulum is connected with the front end of penholder, it is characterized in that: also comprise spring, drive mechanism and briquetting, described briquetting has three, is evenly distributed on the side of penholder front end; Described drive mechanism is positioned at the inside of front end and the penholder protecgulum of penholder, and this drive mechanism has three drive links, and one end of three drive links also props up mutually with three briquettings are corresponding one by one respectively, and the other end of three drive links props up one end of spring; Described three drive links prop up briquetting one end distance each other and are greater than three drive links and prop up spring one end distance each other; Described spring is positioned at the inside of penholder protecgulum.According to writing style, be generally to write with the front end that these three fingers of thumb, forefinger and middle finger are held penholder, so being provided with three and briquetting, briquetting and drive link be arranged on the side of penholder front end, hold comfortablely, press conveniently; Three drive links prop up briquetting one end distance each other and are greater than three drive links and prop up spring one end distance each other, can be by the other end to sinciput during one end of briquetting extruding drive link, compression spring above, drives pen core to advance, and then nib is stretched out, can write; Unclamp finger, pen core can automatic backing under the active force of spring reset, and then nib rebounds, and is protected timely.
One end that three drive links described in the utility model prop up briquetting interconnects, and one end that three drive links prop up spring interconnects; Described interconnective part can be triangle or circular circulus.The end of three drive links interconnects and makes transmission mechanism structure more firm, props up briquetting and spring is more firm, transmission better effects if.
Penholder described in the utility model is divided into penholder front portion and penholder rear portion, and wherein penholder front portion is cylindrical structure, and penholder rear portion is square body structure.Before penholder, the design at circle rear makes pen be difficult for tumbling.
Spring described in the utility model, drive mechanism and penholder protecgulum are metal system.Metal spring, drive mechanism good springiness, not yielding, sturdy and durable; Not easily damaged when metal penholder protecgulum falls, can protect better nib.
Mechanical pencil described in the utility model also comprises grab, and described grab is connected to the side of the nearly rear end of penholder.The design of grab can be clipped on the article such as book pen, is difficult for dropping.
The utility model compared with prior art, have the following advantages and effect: more reasonable structure, nib user not the used time can be automatically withdrawn in penholder protecgulum, solved in life because nib is exposed to and outer caused nib to break or stay the problem of ink marks on article, easy to use; In addition, before penholder, the design at circle rear makes pen be difficult for tumbling.
Accompanying drawing explanation

Fig. 2 is that the utility model is equipped with the schematic diagram that pen core and briquetting are upspring.
Fig. 3 is that the utility model is equipped with the schematic diagram that pen core and briquetting are pressed.
In figure: penholder 1, penholder front portion 11, penholder rear portion 12, penholder protecgulum 2, grab 3, spring 4, drive mechanism 5, drive link 51, briquetting 6, nib 7.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail.
Referring to Fig. 1-Fig. 3, the present embodiment comprises penholder 1, penholder protecgulum 2, grab 3, spring 4, drive mechanism 5 and briquetting 6, described grab 3 is connected to the side of penholder 1 nearly rear end, described penholder protecgulum 2 adopts and is threaded with the front end of penholder 1, the front end of penholder protecgulum 2 is porose, and nib 7 is extended; Described briquetting 6 one has three, is evenly distributed on the side of penholder 1 front end; Described drive mechanism 5 is positioned at the inside of front end and the penholder protecgulum 2 of penholder 1, this drive mechanism 5 has three drive links 51, one end of three drive links 51 separate and interconnect and respectively with three briquettings 6 one by one corresponding, mutually prop up, the other end of three drive links 51 is gathered and is interconnected the one end that props up spring 4, and the other end of spring 4 connects pen core; Described spring 4 is positioned at the inside of penholder protecgulum 2.
In the present embodiment, described penholder 1 is divided into penholder anterior 11 and penholder rear portion 12, and wherein penholder anterior 11 is cylindrical structure, and penholder rear portion 12 is square body structure.
