Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises penholder, pen core and the cap for brush, described penholder is connected to form by last penholder, following penholder, be respectively equipped with different pen core in the upper and lower penholder, described pen core comprises invisible ink pen core and developer water fillable.Realized being with a secret writing pen not only can write latent type literal but also can develop out, made and carry and use all very convenient concealing the type literal.
As preferably, the described penholder head of going up is provided with a pen core fixed cover, the tapered and conical surface of pen core fixed cover with bore end smooth transition, the conical surface and the vertex of a cone be smooth transition also, pen core fixed cover center is provided with pen core, described pen core is the invisible ink pen core.Both increased aesthetic feeling, and also made the installation of pen core more become firm.
As preferably, the described penholder head pen core fixed cover back of going up also is provided with a short step, the described cap for brush is formed by connecting at the top by the interior cap for brush, the outer cap for brush, the interior bore of the cap for brush and the external diameter of described short step match in described, and the interior bore of the described outer cap for brush and the described external diameter of going up penholder match.Guarantee the sealing at nib place, guarantee that pen core can not volatilize when not using, increase the service life.
As preferably, also be provided with a step between described short step and the described pen core fixed cover, described step periphery slightly is tapering, described step bottom and described short step smooth transition, and described step top is consistent with described pen core fixed cover bottom.Make pen more become attractive in appearance and also more become firm.
As preferably, the described afterbody of going up penholder is provided with an individual cavity, the head of following penholder is provided with the step of band tapering, and the head of following penholder is socketed in the individual cavity of penholder afterbody, and the internal diameter of described individual cavity matches with the external diameter of the bottom of the step of described band tapering.Make the penholder conduct simultaneously cap for brush of penholder down, sealing is good equally, saves cost, has also controlled the volume of whole pen.
As preferably, also be provided with a thin shape step on the step of described band tapering, thin shape step center is provided with pen core, and described pen core is the developer water fillable, and pen core is installed firmly.
As preferably, also be provided with a short step of following penholder between the step of described thin shape step and band tapering, described thin shape step and the described short step smooth transition of penholder down, the external diameter of the described short step of penholder down and the interior bore of the described interior cap for brush match, and the described external diameter of penholder down and the interior bore of the described outer cap for brush match.
As preferably, be provided with pen clip outside the described outer cap for brush, the outer cap for brush is made by transparent plastic, and the interior cap for brush is made by opaque plastics.
The beneficial effects of the utility model are: upper and lower penholder connects into the one-pen bar, is with a secret writing pen not only can write latent type literal but also can develop out with concealing the type literal, makes to carry and use all very convenient; Simultaneously, the head of following penholder is socketed in the afterbody of penholder, makes to go up the cap for brush that penholder is a penholder under latent type pen is again, saves cost, has also controlled the volume of secret writing pen; In addition, the cap for brush is made up of the inside and outside cap for brush, has increased sealing.
