Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with this Accompanying drawing in utility model embodiment, carries out clear, complete to the technical scheme in this utility model embodiment Ground describes, it is clear that described embodiment is a part of embodiment of this utility model rather than whole realities Execute example.

As Figure 1-5, a kind of anti-hands shadow pen of the present embodiment, including the penholder 1 of pen clip, pen core 2 and tubular, The cone 3 coordinated with pen core 2 tip is installed in penholder 1 lower end, and cone 3 and penholder 1 connecting portion are provided with inwardly Side tighten up inclined-plane 4, tighten up inclined-plane 4 and be embedded mounted LED lamp 5, penholder 1 outer wall installs microswitch 6； Pen clip includes that clamp 7 and cylinder 8, cylinder 8 lower end can be inserted into penholder 1 upper end, and clamp 7 is arranged on cylinder 8 Side, cylinder 8 bottom is provided with the battery compartment 9 installing battery, battery compartment 9 lower ending opening, and opening inner side is arranged Female thread also installs rotating end cap 10, and rotating end cap 10 is installed crimp spring and the first electric conductor 11, electricity The second electric conductor 12 is installed at top, storehouse, pond 9, and first electric conductor the 11, second electric conductor 12 all stretches out cylinder 8 Periphery；Mounting fixing parts between rotating end cap 10 lower end and penholder 1 inwall；Penholder 1 upper inside wall has perpendicular To 2 chutes, be respectively provided with in 2 chutes the 3rd electric conductor 13 and respectively with the first electric conductor 11, second Electric conductor 12 coordinates；First electric conductor the 11, second electric conductor the 12, the 3rd electric conductor 13, LED 5 and Wired in series is passed through between microswitch 6.

Specifically, the anti-hands shadow pen that the present embodiment provides, on the penholder 1 above pen core 2 tip Mounted LED lamp 5, therefore LED 5 is arranged on its lower end relative to penholder 1, can be closer to books such as paper Write region, therefore can fundamentally solve hands shadow and occur, make to write and facilitate effect more preferable；It addition, LED 5 are embedded to be arranged on and tighten up on inclined-plane 4, utilize that tightens up inclined-plane 4 inwardly to roll oblique structural defence, the most not Contact with desktop, thus be avoided that damage extends its service life.Fixture is used to be easy to pen clip and penholder 1 Fixing, dismounting；Battery compartment 9 is arranged on the cylinder 8 of pen clip, can be hidden in penholder 1 upper end, therefore have It is beneficial to reduce the volume of product, balances center of gravity, make the experience write more preferable；First electric conductor 11, second lead The contact of body and the 3rd electric conductor 13 uses slide construction, it is possible to increase contact surface, it is ensured that the stability of conducting. When using first, by mounting batteries in battery compartment 9, rotating end cap 10 of then screwing on, then conduct electricity first Body the 11, second electric conductor 12 is respectively aligned to chute, the cylinder 8 of pen clip inserts penholder 1 top and makes circuit even Logical, control microswitch 6 lightening LED lamp 5 the most as required, can use, use complete, then press One time LED 5 just can be closed by microswitch 6.When pen core 2 needs to change, as long as extracting pen clip, New pen core 2 is inserted in penholder 1.

Wherein, the relative position of first electric conductor the 11, second electric conductor 12 is with cylinder 8 setting substantially symmetrical about its central axis Preferably, it is simple to clamp 7 and penholder 1 are installed and coordinated.Further, the 3rd electric conductor 13, LED 5 With the wire of series connection is arranged in penholder 1 barrel between microswitch 6, it is to avoid the accident of wire fractures etc. hidden Suffering from, safety is good.

As in figure 2 it is shown, the fixture in the present embodiment, by the enlarging cylinder 14 being arranged on rotating end cap 10 bottom surface Constituting with the boss arranged on penholder 1 inwall, enlarging cylinder 14 coordinates with boss can be fixed on penholder 1 by pen clip Upper end.Using said structure convenient use, low cost, be easy to manufacture, fixture can also use buckle etc. Bridging arrangement.

As shown in Figure 4, the present embodiment has the loose slot 15 of sector, the first conduction in the middle part of rotating end cap 10 Body 11 is arranged in loose slot 15.Loose slot 15 is set, makes the first electric conductor 11 can be in loose slot 15 Regulation direction and angle, it is simple to the first electric conductor 11 is finely adjusted, advantageously ensures that the first electric conductor 11 Stable contact is formed with the 3rd electric conductor 13.

As it is shown in figure 5, for convenience to the installation of pen core 2 and fixing, the present embodiment anti-hands shadow pen as above, Rotating end cap 10 bottom center position is provided for the fixing annulus 16 of pen core 2.Annulus 16 and pen core 2 Upper end connects fixing, pen core 2 during writing can be avoided to occur rocking, thus affect writing quality.

As it is shown in figure 1, the present embodiment is 2 tightening up the LED 5 being symmetrically installed on inclined-plane 4.LED Lamp 5 can be symmetrical arranged multiple, by increasing capacitance it is possible to increase brightness of illumination, it is to avoid because gripping the different of angle illumination occur Dead angle, uses more convenient.

This utility model steady quality, good illumination effect, volume is little, it is simple to carries and uses, especially electricity In the connected mode on road, use the conductive component of directly contact, it is ensured that the stability of circuit turn-on.

The technology contents of the most detailed description of this utility model is known technology.
