Background technology
Wooden and paper-roll pencil is write conveniently to people's work, learning tape, but has consumed again the forest reserves of a large amount of preciousnesses simultaneously.Existing wooden and paper-roll pencil need to be rolled up and cuts penholder and pen core is fined away and just can be write, when pen is used 6-7cm, often because holding a pen inconvenience, thrown into dustbin, paper, wood chip after volume is cut cannot reclaim use especially, cause very large waste, and pencil-lead exposes easily disconnected core.Therefore, need a kind of continuous core, pen core utilization rate high, economize on resources, the pencil of environmental protection.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of fine arts propelling pencil that improves pen core utilization rate is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of fine arts propelling pencil, comprise pen core, penholder, in described penholder cavity, be provided with successively pen core propeller, pen core retaining core pipe from top to bottom, pen core is placed in pen core retaining core pipe, it is characterized in that, described pen core propeller consists of nut, screw rod, riffled tube, and described nut is fixedly installed on penholder cavity middle part, and described screw flight matches with the screw thread of nut, riffled tube respectively; Described screw rod is placed in riffled tube cavity, and its lower end screws in nut, and is placed in pen core top, and screw rod, pen core are coaxial; Described riffled tube upper end is provided with rotary handle, and rotary handle is placed in outside the port of penholder upper end, and rotary handle is connected with riffled tube by cylindricality contiguous block, and riffled tube rotates clamping by cylindricality contiguous block and penholder inwall.
Described cylindricality contiguous block sidewall is provided with annular protrusion, and penholder inwall is provided with the cannelure matching with annular protrusion, and riffled tube is rotatably connected in penholder cavity by annular protrusion, cannelure.
Described rotary handle external diameter is greater than penholder internal diameter, and equates with penholder external diameter.
Described pen core retaining core pipe outer wall is provided with spacing block set, and pen core retaining core pipe is fixed in penholder inner chamber by spacing block set.
The length of described screw rod is greater than the length of pen core.
Described screw diameter is less than the internal diameter of pen core retaining core pipe, and is more than or equal to the diameter of pen core.
On described screw rod, the spacing of adjacent thread is 3-6mm.
In the utility model, pen core propeller consists of nut, screw rod, riffled tube, and nut is fixed in penholder inner chamber.The utility model needs knockout in use, only need pin on the other hand penholder, pin on the other hand rotary handle, by rotating clockwise or counterclockwise rotary handle, cylindricality contiguous block rotates in penholder cavity, thereby drive riffled tube to rotate, screw rod is along with riffled tube rotates, because screw rod screws in nut, nut is fixed in penholder cavity, thus screw rod can along with riffled tube rotate and in nut turn advance, thereby screw rod is mobile toward penholder below, final pushing pen refill skids off outside nib, realizes the continuous knockout of pencil.The utility model is not when being used, can pin on the other hand penholder, pin on the other hand rotary handle, counterclockwise or the rotary handle that turns clockwise, make screw rod mobile toward penholder top, between pen core and screw rod, occur behind space, prop up pen core tip, pen core is return in penholder, guaranteed pencil continuous core when not using.
The setting of pen core retaining core pipe is that protection pen core is by its continuous core in order to make pen core firm in penholder cavity, and the spacing block set on pen core retaining core pipe outer wall, is for pen core retaining core pipe is better fixed in penholder.The length of screw rod is greater than the length of pen core, and the diameter of screw rod is less than the internal diameter of pen core retaining core pipe, and is more than or equal to the diameter of pen core, even be also left several centimeters after the long-time use of pen core, also can allow screw rod that pen core is ejected to penholder and continue outward to use.On screw rod, the spacing of adjacent thread is 4-6mm, revolves the rotary handle that turns around, and can guarantee pen core knockout 4-6mm.
The utility model is skillfully constructed, simple in structure, manufactures easily, and cost is low, continuous core, and pen core utilization rate is high, economizes on resources, environmental protection, and can assist user to grasp correct holding posture, there is the wide market space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pen core retaining core pipe in the utility model;
In figure: 1 pen core, 2 penholders, 3 pen core retaining core pipes, 4 nuts, 5 screw rods, 6 riffled tubes, 7 rotary handles, 8 cylindricality contiguous blocks, 9 annular protrusions, 10 spacing block sets.
The specific embodiment
A kind of fine arts propelling pencil, comprise pen core 1, penholder 2, in penholder cavity, be provided with successively pen core propeller, pen core retaining core pipe 3 from top to bottom, pen core is placed in pen core retaining core pipe, pen core retaining core pipe 3 outer walls are provided with spacing block set 10, and pen core retaining core pipe is fixed in penholder 2 inner chambers by spacing block set.
