Abstract

The utility model relates to a sign pen with a telescopic length-adjustable pen refill. A matched screw cap capable of rotating left and right is arranged at the top of a pen holder and is connected with the pen refill in the pen holder. The sign pen provided by the utility model has convenient use and simple structure, and is worthy of generalization.

Description

The signature pen of scalable pen core length

Technical field

The utility model relates to a kind of daily signature pen that writes, specifically a kind of signature pen of scalable pen core length.

Background technology

At present, existing signature pen, pen core length immobilizes, in case pen core has shortened, just influence is used.

The utility model content

In order to solve the problem of the manual trouble of signature pen in the past, the utility model provides a kind of signature pen of scalable pen core length, and the signature pen of this scalable pen core length need not be pushed, and is easy to use.

The technical scheme that its technical problem that solves the utility model adopts is: this utility model comprises a cap, penholder and pen core, the signature pen of this scalable pen core length has an identical silk cap that can left rotation and right rotation for the penholder top, this cap is inserted the pen core that is connecting in the penholder, during use, the scalable pen core length of rotation silk cap is used signature pen according to demand.

The beneficial effects of the utility model are: the signature pen of this scalable pen core length is easy to use, simple in structure, is worthy to be popularized.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is a structural principle schematic diagram of the present utility model.

Among the figure, 1. a cap, 2. penholder, 3. pen core.

The specific embodiment

In the drawings, this utility model comprises a cap 1, penholder 2 and pen core 3, the signature pen of this scalable pen core length is that penholder 2 tops have an identical silk cap 1 that can left rotation and right rotation, this cap 1 is inserted the pen core 3 that is connecting in the penholder 2, during use, rotation silk cap 1 scalable pen core 3 length are used signature pen according to demand.
