The specific embodiment

See also Fig. 1 to shown in Figure 3, the portable pen of key ring of the present utility model, it comprises: pen core 1, penholder 2, shell 8, pushing part 5 and key ring 6.Described pen core 1 is installed with in penholder 2.Shell 8 comprises bonnet 3 and cooperates the protecgulum 4 of cutting ferrule penholder 2 with bonnet 3.Bonnet 3 and protecgulum 4 erection weldings are together to hold penholder 2 and pen core 1.Various pattern can be printed in its shell 8 surfaces, in order to increase selling point, does not repeat them here.Described bonnet 3 is provided with chute 30, and penholder 2 is installed with in chute 30.Described chute 30 is arranged to plane of bending, and chute is transited into deep-slotted chip breaker 301 in two ends about in the of 30, and described chute 30 is provided with stuck point 302, and described stuck point 302 is used with pushing part 5 and holds moving of restriction penholder 2.Bonnet 3 tops are provided with the key ring hole 31 that is connected with key ring 6.Key ring 6 is located at an end of the portable pen of key ring, comprises that two young circles 60, C enclose 61 and 8 word circles 62.Key ring 6 is provided with 61, one C circles 61 of two C circle and is connected with two young circles 60, and another C encloses 61 and is connected with key ring hole 31, and two C couple together with 8 word circles 62 between enclosing 61.Have fixing hole 21 on the penholder 2, pushing part 5 passes in the fixing hole 21 that chute 30 inserts penholders 2 and is connected and fixed with penholder 2, drive penholder 2 and together slide up and down along chute 30, realization penholder 2 and the pen core 1 that is installed with wherein are flexible in protecgulum 4 and bonnet 3 formed cavity volumes.

At first pen core 1 is packed in the penholder 2 during assembling, again the penholder 2 that installs pen core 1 is put in the chute 30 of bonnet 3, then pushing part 5 being passed bonnet 3 by chute 30 inserts in the fixing hole 21 at penholder 2 places, and it is pushing part 5 is fixing with penholder 2 with glue, match completed assembling is corresponding with protecgulum, adopt ultrasonic wave to be connected together between bonnet 3 and the protecgulum 4, one of them C that key ring 6 is provided with encloses in the key ring hole 31 of 61 snare bonnets 3 and gets final product at last.

During work, pushing part 5 is promoted along chute 30, when being pushed into chute 30 lower ends, pushing part 5 holds with the stuck point 302 of bonnet 3, block penholder 2 and be installed with pen core 1 in penholder 2, limit penholder 2 and move up, penholder 2 upwards slides when preventing to write, influence is write, and can normally use and write this moment; When not working, pushing part 5 is upwards promoted, push to then when pushing part 5 and quit work, when pushing part 5 slided into chute 30 upper ends, pushing part 5 held with the stuck point 302 that the chute upper end is provided with, and prevents that penholder 2 is to lower slider.

See also Fig. 4 to shown in Figure 7, another embodiment of the portable pen of key ring of the present utility model, the difference of itself and the foregoing description is: on the chute 30 stuck point 302 can be set, but the deep-slotted chip breaker 301 that chute 30 upper and lower ends are arranged to suddenly change, and the oral area width of deep-slotted chip breaker 301 is less than its Breadth Maximum.Its deep-slotted chip breaker 301 can adopt is arranged to more than half circular arc, as 3/4 circular arc.It further is provided with locking member 7, when pushing part 5 passes the fixing hole 21 at bonnet 3 insertion penholders 2 places by chute 30, locking member 7 is locked together with pushing part 5, and pushing part 5, locking member 7 are fixed together with penholder 2, and described pushing part 5 can be in fixing hole 21 rotations with locking member 7.Described pushing part 5 is arranged to length different long limit and minor face, and its long edge lengths is greater than the oral area width of deep-slotted chip breaker 301, bond length is less than the oral area width of deep-slotted chip breaker 301, when pushing part 5 slides, the minor face of pushing part 5 slides along chute 30, when sliding into the deep-slotted chip breaker 301 of chute upper end or lower end, and rotation pushing part 5, to grow the limit and be threaded to laterally, pushing part 5 will be held deep-slotted chip breaker 301.Locking member 7 can adopt locking mechanisms such as screw, bolt.

During work, rotation pushing part 5, the long limit that is held in the horizontally set of deep-slotted chip breaker 301 is rotated into minor face, promotes pushing part 5, pushing part 5 is slided along chute 30, when being pushed into the deep-slotted chip breaker 301 of chute 30 lower ends, rotation pushing part 5, the horizontal long checkpost that pushing part 5 horizontal minor faces at deep-slotted chip breaker 301 are rotated into closure state during with activity is held in the deep-slotted chip breaker 301, and penholder 2 upwards slides when preventing to write, influence is write, and can normally use and write this moment; When not working, the horizontal long limit that pushing part 5 is held in deep-slotted chip breaker 301 is rotated into the minor face of active state, upwards promote pushing part 5, push to then when pushing part 5 and to quit work, when pushing part 5 slides into the deep-slotted chip breaker 301 of chute 30 upper ends, the pushing part 5 of active state laterally is rotated into the horizontal long limit of closure state at the minor face of deep-slotted chip breaker 301, is held in the deep-slotted chip breaker 301, prevent that penholder 2 is to lower slider.

The specific embodiment of the above is a better embodiment of the present utility model, is not to limit concrete practical range of the present utility model with this, and the equivalence that all shapes according to the utility model, structure are done changes all in protection domain of the present utility model.
