Abstract

A pen with telescopic core features that its internal sleeve tube the first and the second stop rings respectively on its front and back ends, a load-bearing ring can slide on the internal sleeve tube between said two stop rings, and an axle rod passing through the internal flange at the front end of a hollow tube is connected with a sleeve ring via spiral threads.

Description

technical field [0001] The invention relates to an office writing tool, in particular to a pen with a retractable pen core. Background technique [0002] In the design field of writing pens, there are many different designs for the structure used to operate the expansion and contraction of the pen core. Among them, the most common one is a commonly called push-type pen, and its specific structure is as follows: Figures 1 to 4 As shown, the push-type pen 1 generally includes an outer pen tube 10 with several guide rails 101 inside the tail end, a button 11 with a ring-shaped ratchet 111 at the front end, an inner sleeve 12 with a ring-shaped ratchet 121 at the rear end, A set of pen core 13 in the inner casing 12 and a set of back-moving spring 14 on the front end of the pen core 13; figure 1 When the button 11 is pressed as shown, the annular ratchet 111 at the front end of the button 11 can slide linearly forward along several corresponding guide rails 101 of the outer pe...
