In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the safety pen that a kind of child of preventing opens, comprise penholder, the cap for brush, drive unit and pen core, described pen core is arranged in described penholder, on described pen core, be provided with bulge loop, described pen core front end sleeve is provided with elastic parts and limits described elastic parts by described bulge loop and moves upward, described drive unit comprises connecting rod, dop and the positioner matching with described dop, the described cap for brush is set on described connecting rod, described connecting rod is fixedly connected with described dop, described dop is connected with described pen core, described dop side is provided with ridge, described cap for brush lower end is provided with several grooves, all described grooves connect and are shape of threads, described ridge upper end and described groove match, described positioner is fixed on the inwall of described penholder, described positioner comprises several draw runners of even setting, the end of all described draw runners is to the inclined-plane of the same side inclination, between adjacent draw runner, be arranged at intervals with barrier rib, on described penholder madial wall, be fixedly installed several annular fixed heads, all described annular fixed heads are arranged in parallel, on described pen core, be fixedly installed several levers, described lever is positioned at described annular fixed head top, on all described annular fixed heads, all offer the open slot matching with described lever, on described pen core, be also provided with push rod, on described penholder, also offer the through hole passing for all described push rods.After pen is finished using, pen core is recovered in penholder, move horizontally push rod, by pen core rotation, thereby make lever leave the open slot on annular fixed head, thereby can not, by pen core discharge by pressing penholder, avoid child directly pen core to be extruded to penholder.When needs are used, as long as rotating push-rod is all aimed at the open slot on corresponding annular fixed head by all levers, finally press the cap for brush pen core is pressed out in penholder.
In technique scheme, on the end, outer end of described push rod, be provided with striped.Increase and the friction of pointing, facilitate mobile putter.
In technique scheme, the inner ring diameter of described annular fixed head and described pen core diameter match.Make lever integral body all on annular fixed head, fixed effect is better.
In technique scheme, on described penholder lateral wall, be also arranged with protective sleeve.The effect that protective sleeve mainly plays is to block the through hole of offering on penholder, makes child can't see push rod, cannot use push rod, further prevents that child from releasing penholder by pen core, and protective sleeve can also protect penholder to prevent from being scratched.
The utility model compared with prior art, has following beneficial effect: the utility model can prevent that child from opening the cap for brush or pressing out pen core, safe.On the end, outer end of push rod, be provided with striped, increase and the friction of pointing, facilitate mobile putter.Lever integral body is all on annular fixed head, and fixed effect is better.The effect that protective sleeve mainly plays is to block the through hole of offering on penholder, makes child can't see push rod, cannot use push rod, further prevents that child from releasing penholder by pen core, and protective sleeve can also protect penholder to prevent from being scratched.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1-Fig. 4, the safety pen that a kind of child of preventing opens, comprise penholder 1, the cap for brush 2, drive unit 3 and pen core 4, described pen core 4 is arranged in described penholder 1, on described pen core 4, be provided with bulge loop 5, described pen core 4 front end sleeves are provided with elastic parts 6 and are moved upward by the described elastic parts 6 of described bulge loop 5 restriction, when pen core 4 is forced out penholder 1, elastic parts 6 is compressed, when pen core 4 is regained penholder 1, 6 pairs of pen cores of elastic parts have a thrust, make the more naturally quick of pen core 4 withdrawals.
Described drive unit 3 comprises connecting rod 31, dop 32 and the positioner 33 matching with described dop 32, the described cap for brush 2 is set on described connecting rod 31, described connecting rod 31 is fixedly connected with described dop 32, described dop 32 is connected with described pen core 4, described dop 32 sides are provided with ridge 321, the described cap for brush 2 lower ends are provided with several grooves 21, all described grooves 21 connect and are shape of threads, described ridge 321 upper ends and described groove 21 match, when the groove 21 of the cap for brush 2 and the ridge 321 of dop 32 are connected, the cap for brush 2 is not easy to be rotated.
Described positioner 33 is fixed on the inwall of described penholder 1, described positioner 33 comprises several draw runners 331 of even setting, the end of all described draw runners 331 is to the inclined-plane of the same side inclination, between adjacent draw runner 331, be arranged at intervals with barrier rib 332, when the ridge 321 of dop 32 is stuck on barrier rib 332, pen core 4 is in penholder 1 outside and be fixed, and when the ridge 321 of dop 32 is not having in the groove of barrier rib 332, pen core 4 is retracted in penholder 1.
On described penholder 1 madial wall, be fixedly installed several annular fixed heads 11, all described annular fixed heads 11 are arranged in parallel, and the inner ring diameter of described annular fixed head 11 and described pen core 4 diameters match.Make lever 41 integral body all on annular fixed head 11, fixed effect is better.On described pen core 4, be fixedly installed several levers 41, described lever 41 is positioned at described annular fixed head 11 tops, on all described annular fixed heads 11, all offer the open slot 7 matching with described lever 41, when lever 41 does not have in the position above open slot 7, lever 41 plays the effect that stops that pen core 4 moves down.
On described pen core 1, be also provided with push rod 8, on described penholder 1, also offer the through hole 9 passing for all described push rods 8.All push rods 8 can move up and down in through hole 9.On the end, outer end of described push rod 8, be provided with striped.Increase and the friction of pointing, facilitate mobile putter 8.
On described penholder 1 lateral wall, be also arranged with protective sleeve.The effect that protective sleeve mainly plays is to block the through hole 9 of offering on penholder 1, makes child can't see push rod 8, cannot use push rod 8, further prevent that child from releasing penholder 1 by pen core 4, and protective sleeve can also protect penholder 1 to prevent from being scratched.
After pen is finished using, pen core 4 is recovered in penholder 1, move horizontally push rod 8, by pen core 4 rotations, thereby make lever 41 leave the open slot 7 on annular fixed head 11, at this time pressing the cap for brush 2 cannot press out pen core 4 outside penholder 1, when child plays pen, directly pressing the cap for brush 2 cannot press out pen core 4, has prevented the injury that 4 couples of children of pen core or furniture cause.When needs are used, as long as rotating push-rod 8 is all aimed at the open slot 7 on corresponding annular fixed head 11 by all levers 41, meanwhile, through hole 9 has enough large model can move up and down all push rods 8 in through hole 9, just pen core 4 can be pressed out outside penholder 1.
