Technical Field

The invention relates to the field of stationery, in particular to a pen holder capable of being opened and closed longitudinally.

Background

The pen comprises a pen holder and a pen core, wherein the traditional pen holder consists of an upper pen shell and a lower pen shell, and the upper pen shell and the lower pen shell are connected through a threaded connection structure. The traditional pen holder connecting structure has the following defects: the pen holder consisting of the upper pen shell and the lower pen shell is inconvenient for arranging a circuit inside the pen shell; poor contact is likely to occur when the upper pen shell and the lower pen shell are connected by a circuit.

Disclosure of Invention

The invention solves the technical problem of providing a pen holder which can replace a pen core and is convenient for arranging a circuit in a pen shell.

The technical scheme adopted by the invention for solving the technical problems is as follows: the penholder comprises a main shell and an auxiliary shell, wherein the main shell and the auxiliary shell are longitudinally connected along the penholder.

The further preferable scheme of the invention is as follows: the main casing with the vertical junction of auxiliary housing is equipped with the guide rail, the main casing with the auxiliary housing passes through the guide rail is connected, the auxiliary housing is followed the guide rail slides and can open or close the pen-holder. The opening and closing between the main shell and the auxiliary shell are easy.

The further preferable scheme of the invention is as follows: the cross section of the guide rail is in a T shape or an L shape, a V shape or an inclined plane shape, the main shell and the auxiliary shell are not easy to misplace, and the production and the manufacture are easy.

The further preferable scheme of the invention is as follows: the main casing with the vertical junction of sub-casing is equipped with vertical sawtooth, the main casing with sub-casing passes through the sawtooth is connected, and the separation or combination the main casing with the sawtooth between the sub-casing can be opened or closed the pen-holder. The main shell and the auxiliary shell are fixed effectively.

The further preferable scheme of the invention is as follows: the penholder is provided with a sleeve, and the main shell and the auxiliary shell are fixed with good effect.

The further preferable scheme of the invention is as follows: the sleeve is made of elastic materials, the sleeve is sleeved on the pen holder through elastic pressure, and the sleeve is fastened on the main shell and the auxiliary shell through elasticity and friction force. The main shell and the auxiliary shell are fixed effectively.

The further preferable scheme of the invention is as follows: the sleeve pipe pass through threaded structure with the main casing body with vice casing is connected, the screw thread on the sleeve pipe is the internal thread, the main casing body with the screw thread of vice casing is the external screw thread. The main shell and the auxiliary shell are fixed effectively.

The further preferable scheme of the invention is as follows: the tail connecting device is arranged at the tail connecting position of the main shell and the auxiliary shell and consists of a plug and a jack, the plug and the jack are consistent in shape and matched in cross section size, and the cross section shapes of the plug and the jack are circular, rectangular, triangular or trapezoidal. The main shell and the auxiliary shell are fixed effectively.
