The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

As shown in Figure 1, Figure 2, Figure 3 shows: a kind of counting double-purpose pen of writing of the present invention, comprise front penholder 3, the rear penholder 5 being connected with front penholder 3 screw threads 4, be positioned at the pen core 2 of front penholder 3, rear penholder 5, the rear end of pen core 2 is equipped with pen core cap 6, on rear penholder 5, have draw-in groove 8, pen core cap 6 one sides are provided with the pen core cap button 7 stretching out outside draw-in groove 8, described draw-in groove 8 is divided into long longitudinal groove 13, lateral trench 14 and short longitudinal groove 15, and long longitudinal groove 13, lateral trench 14 and short longitudinal groove 15 are communicated with successively; The rear end of rear penholder 5 arranges counter 9, and the count button 10 on counter 9 is positioned at pen core cap 6 rears, and the SR 11 on counter 9 stretches out the rear end of rear penholder 5.The front end of front penholder 3 is provided with the cap for brush 1.One side of rear penholder 5 has the forms 16 that the digital display screen 12 for counter 9 stretches out.The setting of forms 16 makes reading out data convenient.

As the optimization of technical solution of the present invention, the length of short longitudinal groove 15 is less than the length of long longitudinal groove 13, and the diameter of draw-in groove 8 width and pen core cap button 7 is consistent, and these two technical characterictics can be guaranteed the stability of pen core cap button 7 clampings.

As shown in Figure 4: in use, when just using normal writing function, slightly unclamp the screw thread 4 of front penholder 3, rear penholder 5, again pen core cap button 7 is pushed to short longitudinal groove 15 places, and then tighten the screw thread 4 of front penholder 3, rear penholder 5, at this moment nib is exposed outside, because pen core cap button 7 is stuck in short longitudinal groove 15 places, can not move, so nib and pen core 2 can not inside contract in the used time of doing of writing the power of being subject to, thus realize normally write merit.
