Slidable type pen

Abstract

The invention provides a slidable type pen comprising an outer rod and an inner rod which is sleeved in the outer rod, wherein the inner rod comprises a sleeve located at the front end, and a spring tongue which is arranged on the back end wall of the sleeve and is raised upwards; a wedged baffle is arranged at the back end part of the spring tongue; the outer rod is provided with a slide hole and a positioning hole located behind the slide hole; the slide hole is provided with a slide key; the slide key comprises a slide key body, two limiting side walls located below the slide key body and a stopping cross beam arranged between the two side walls; and limiting bulges are arranged at the outer sides of the limiting side walls. When the slidable type pen is mounted, only the inner rod is sleeved in the outer rod and the slide key is pressed into the slide hole to be matched with other parts including a refill, a spring mechanism and a pen cone to finish the installation; in the whole process, the assembling is simple; and furthermore, the slidable type pen is convenient to use and can be randomly opened and closed by back and forth sliding of a thumb, and the trifles that the thumb needs to move to the upper end of the pen to press when the pen with a cam structure is opened and closed are avoided.

Description

technical field [0001] The invention relates to a writing instrument. Background technique [0002] At present, most of the commonly used pens are push-type, including a pen holder, in which a replaceable refill is inserted. The rear end of the pen holder is a cam mechanism composed of a cam body, a cam rod and a rotor. When the cam lever at the end is turned, the nib of the pen core can be stretched out or retracted from the front end of the pen cone. [0003] Since the above-mentioned pen is connected in series with the rotor and the cam rod to the rear end of the pen core in the axial direction, the axial length is relatively long, so it is impossible to produce a small pen with the same capacity of the pen core but a simplified whole pen; However, in addition, the rotor itself has a certain radial width, which greatly affects the slender appearance of the pen. [0004] The cam structure of the above-mentioned pen tool makes the whole pen have many parts and complicated...
