The safe pen is characterized in that thepen shell consists of an inner shell and an outer shell, the middle part of the inner shell is provided with a pen core hole, the tail part of the inner shell is fixedly provided with a touch block,the inside of the outer shell is provided with a limit groove corresponding to the touch block and also provided with spiral patterns, the inner wall of the outer shell is provided with arc-shaped regress patterns near the terminals of the spiral patterns, and the front end of the pen core tip is provided with a rectangular limit rod. The utility model prevents the damage to the children caused bythe pen nib, thereby being safe and reliable.

Description

A kind of children use the safety pen

Technical field:

The utility model relates to a kind of stationery, especially a kind of children use the safety pen.

Background technology:

In the prior art, technique known is that pen used in everyday all is to manufacture and design according to the safety standard of being grown up, these nibs are sharp-pointed, dangerous little to being grown up, but when children use, easily because children play mutually each other, quarrel and fight noisily or fault causes and stabs injury, this is the existing in prior technology weak point.

Summary of the invention:

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of children are provided the technical scheme with the safety pen, and the children of this scheme use the safety pen, and the injury of having avoided nib to bring to children is safe and reliable.

This programme is realized by following technical measures: a kind of children use the safety pen, include a circular shell, the pen core that has the pen core termination, be sleeved on the spring on the pen core, the characteristics of this programme are: described shell has inner casing and shell, reservoir hole is arranged in the middle of the described inner casing, afterbody at inner casing is fixed with contact block, be provided with the stopper slot corresponding in the inside of shell with contact block, portion also has spiral lamination in the enclosure, the spiral lamination front end is arranged in the stopper slot, in addition, be provided with arc near the spiral lamination end on the wall in the enclosure and return lines, the front end of described pen core termination has rectangular gag lever post, the spiral lamination front end is a circular arc, and the spring fixture block is arranged in the inner casing reservoir hole.The shell front end has the circular rib circle, and outer casing inner wall has retaining groove, and the raised item corresponding with retaining groove arranged on the inner casing outer wall, and the shell end has bonnet.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because there is spiral lamination in portion in the enclosure in this scheme, the spiral lamination front end is circular arc and is arranged in the stopper slot, can make the gag lever post of pen core termination rotate in the stopper slot fixing, this can use pen, when an inner casing front end is received pressure, then inner casing moves backward, and the contact block of inner casing afterbody just promotes gag lever post, makes gag lever post shift out stopper slot, because the front end of spring is stuck on the spring fixture block of inner casing, so spring can only be to the pusher pen core, under the pressure of spring, pen core termination and pen core are drawn back, final pen core is retracted in the inner casing, has avoided sharp-pointed pen core to stab; Be provided with arc near the spiral lamination end on the outer casing inner wall and return lines, can make the gag lever post periodic duty, the shell front end has the circular rib circle can prevent that inner casing from ejecting from shell; Outer casing inner wall has retaining groove, and the raised item corresponding with retaining groove arranged on the inner casing outer wall, can prevent that inner casing, shell from rotating in use.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Fig. 1 is the structure cut-away view of the utility model specific embodiment.

Fig. 2 is a pen core termination vertical view.

Fig. 3 is the inner casing structural representation.

Fig. 4 is a cut-away view of outer cover.

Among the figure, 1 is stopper slot, and 2 is contact block, and 3 is inner casing, and 4 is the pen core termination, and 5 is gag lever post, 6 is spiral lamination, and 7 is spring, and 8 is the spring fixture block, and 9 is the circular rib circle, and 10 is pen core, and 11 is shell, 12 is reservoir hole, and 13 is the shell bonnet, and 14 for returning lines, and 15 is raised item, and 16 is retaining groove.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

By accompanying drawing as can be seen, the children of this programme use the safety pen, include a circular shell, the pen core 10 that has pen core termination 4, be sleeved on the spring 7 on the pen core 10, the characteristics of this programme are: described shell has inner casing 3 and shell 11, in the middle of the described inner casing 3 reservoir hole 12 is arranged, afterbody at inner casing 3 is fixed with contact block 2, be provided with the stopper slot 1 corresponding with contact block 2 in the inside of shell 11, in shell 11 inner spiral laminations 6 in addition, spiral lamination 6 front ends are arranged in the stopper slot 1, in addition, on shell 11 inwalls, be provided with arc and return lines 14 near spiral lamination 6 ends, the front end of described pen core termination 4 has rectangular gag lever post 5, and spiral lamination 6 front ends are circular arc, in the reservoir hole 12 of inner casing 3 spring fixture block 8 is arranged.Shell 11 front ends have circular rib circle 9, and shell 11 inwalls have retaining groove 16, and the raised item 15 corresponding with retaining groove 16 arranged on inner casing 3 outer walls.Shell 11 ends have bonnet 13.During use, press pen core termination 4, then gag lever post 5 slides in the stopper slot 1 above spiral lamination 6, and is fixed, when not using, click pen core termination 4 again, then gag lever post 5 is just below spiral lamination 6, under the pressure of spring 7, and the end of the shell 11 that slips, because the lines 14 of recurrence is arranged, state before then the gag lever post 5 of pen core termination 4 is got back to again and used is when using, when stinging people or object, can run into inner casing 3, then inner casing 3 has action backward, and the contact block 2 of inner casing 3 afterbodys also moves simultaneously, and gag lever post 5 is released from stopper slot 1, then pen core 10 recedes in the shell, avoids people or object are damaged.
