Abstract
Disclosed is an environment-protective movable pencil. A pencil lead is fixed onto a pencil lead fixing component and fastened into a semicircular sliding rod lead clamping opening; one face of an elastic support of the pencil lead fixing component is placed into a semicircular sliding rod groove and positioned by being pushed into a pencil rod by a press component; the other face of the elastic support of the pencil lead fixing part is combined with teeth inside the pencil rod to reciprocate under matching of a spring by pressing a press post on the press component; the semicircular rod teeth and pencil rod side face teeth alternately downwardly push the pencil lead fixing component and the pencil lead to complete lead discharge under driving of the press post and the spring due to directions of the teeth. The environment-protective movable pencil can be continuously used after pencil lead replacement, thereby achieving the purposes of saving and environmental protection.
Description
Technical field:
Stationery, the environmental protection propelling pencil.Can repeatedly change lead for retractable pencil uses.
Technical background:
At present existing propelling pencil lead for retractable pencil is thin, easily broken, and the pupil uses inconvenience, and thick propelling pencil lead for retractable pencil utilization rate is not high, can not reach the purpose of saving, and lead for retractable pencil is changed shortcomings such as inconvenience.
The utility model content:
Existing propelling pencil mostly is thin lead, and is easily broken, and the pupil uses inconvenience.Solution is; a kind of environmental protection propelling pencil is by penholder 1; press part 2; slip half-round bar 3, lead for retractable pencil fixture 4 is formed, and it is characterized in that: slip half-round bar 3 with link to each other by part 2; and link to each other with penholder 1 usefulness T word groove by pressing part 2; the groove teeth of slip half-round bar 3 are relative with the teeth of penholder 1, and lead for retractable pencil fixture 4 is stuck in the position of the teeth of penholder 1 and slip half-round bar 3 by the elastic support of lead for retractable pencil fixture 4 both sides between slip half-round bar 3 and penholder 1.Penholder 1 is an integral body, saves operation.Penholder 1 is divided into c district, b district, a district, the a district is inner tapered, the center has can be by the aperture of lead for retractable pencil, b district inner side has the zigzag teeth, teeth have direction, and the facing to a district becomes an angle of 90 degrees with inwall, another side be 160 spend to 140 the degree angles between, there is the T word tongue of allocation outside, c district, and T word groove is at teeth face place, side, b district.Press part 2 by shell, spring is pressed post and is formed, and outer casing inner wall has the T word groove of location and by post motion scale, and presses the post guide slot.Slip half-round bar 3, stock, the plumbous mouth of circular folder, the folder mouthful vertical striped of inwall, fixedly lead for retractable pencil does not disorderly rotate, the other end be cylinder with by combine mid portion cross section one-tenth semicircle arcuation in the part 2 by post, the inside radius of semi arch is identical with the radius of the cylinder of lead for retractable pencil fixture 4, cylinder is reliably gone in the semi arch, and vertical center is a groove, and bottom land has teeth, facing to plumbous mouthful of direction of folder becomes an angle of 90 degrees with groove bottom, and another side is 160 to spend between the 140 degree angles.Lead for retractable pencil fixture 4, cylinder, there is the fixedly aperture of lead for retractable pencil at the cylinder center, the flexible support of cylinder bilateral symmetry, support width is consistent with the well width of groove.This propelling pencil can use the same lead for retractable pencil of wooden pencil, can repeatedly change lead for retractable pencil and use, and desirable substitute wood pencil is saved trees, environmental protection, and lead for retractable pencil utilization rate height, it is extensive to be suitable for the crowd, and it is convenient and simple to change lead for retractable pencil.
Description of drawings:
Below in conjunction with accompanying drawing this utility model propelling pencil is described further.
Fig. 1 is a sectional structure chart.
Fig. 2 is the pars intermedia cross-sectional view of slip half-round bar 3.
Penholder 1 among Fig. 1, presses part 2, slip half-round bar 3, lead for retractable pencil fixture 4, lead for retractable pencil 5.
The specific embodiment:
Lead for retractable pencil 5 is packed in the aperture of lead for retractable pencil fixture 4, lead for retractable pencil 5 reinstalls in the plumbous mouth of folder of slip half-round bar 3, one side elastic support of lead for retractable pencil fixture 4 is packed in the pars intermedia groove of slip half-round bar 3, slip half-round bar 3 by the other end cylinder with by the linking to each other according to status requirement of part 2 by post, forever motionless.After slip half-round bar 3 lead for retractable pencil fixtures 4 and lead for retractable pencil 5 combinations, by pushing in the penholder 1 by part 2, interlock by the T word groove of part 2 and the T word groove of penholder 1, the teeth of penholder 1 are relative with the teeth of slip half-round bar 3, the teeth combination of the opposite side elastic support of lead for retractable pencil fixture 4 and penholder 1 side.When press by part 2 by post the time owing to limit by part 2 outer casing inner wall motion scales, the teeth of slip half-round bar 3 are stuck in penholder 1 side teeth because the relation drive lead for retractable pencil fixture 4 of direction moves downward a tooth.Under the effect of spring, driving the slip half-round bar by post and return teeth by part 2.Because the relation of penholder 1 side teeth direction, lead for retractable pencil fixture 4 is stuck in penholder 1 side teeth under the effect of elastic support, can not return teeth.Whenever click by post, lead for retractable pencil 5 to next teeth, uses up up to lead for retractable pencil under the drive of lead for retractable pencil fixture 4.Extracting by part 2 one changes and can take out slip half-round bar 3 lead for retractable pencil fixtures 4 and lead for retractable pencil 5, pushes and can use again after changing lead for retractable pencil.Penholder 1 is pressed part 2, slip half-round bar 3, lead for retractable pencil fixture 4, the center at same central axis.
