Fig. 2 is the use constitutional diagram of a kind of hand-held calculator embodiment of the utility model.

Fig. 3 is the part explosive view of a kind of hand-held calculator embodiment of the utility model.

Fig. 4 is the enlarged drawing of A in Fig. 3.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figures 1 to 4, a kind of hand-held calculator, comprises counter body 1, on body 1, have for inserting the slot 1a of outside integrated chip, described body 1 one sides are fixed with for putting the pen container 2 of pen, and the outlet of pen container 2 has pen container plug 3, has a locked protruding 3a on described pen container plug 3;

Two chutes 5 are arranged at described body 1 bottom, and chute 5 has the first block 5a near one end of pen container plug 3, and chute 5 is sealing state near pen container 2 sealing ends, can prevent that board from skidding off from this one end;

In described chute 5, board 4 is installed, board 4 has two second block 4as corresponding with the first block 5a near pen container sealing end.

As shown in Figure 1, when board 1 slips into chute 5 when interior completely, adjust locked protruding 3a, make locked protruding 3a block the endpiece of board 1, so just make board 1 not skid off, be easy to carry, and pen container plug 3 has also been blocked the pen container 2 that pen is housed simultaneously, prevent that pen from skidding off.

As shown in Figure 2, when needs are used board 1, the part that first locked protruding 3a turn-off can be pinned to board 1, then skids off board 1; When the first block 4a of board 1 and the second block 5a of chute 5 contact, board 1 just can not stretch out again, with this, guarantees that board 1 can not skid off from pen container plug end.In this process, can first take out pen container plug 3, then take out the pen in pen container 2, finally get back into pen container plug 3, prevent pen container plug 3 loss.

More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
