Problems solved by technology

There are still several structures similar to the above-mentioned schemes in the prior art, but they are similar, and there are "clicks". In some important occasions or relatively quiet occasions, noise will be generated when using this type of pen, which cannot satisfy the need for quietness. needs

Embodiment approach

[0025] 1. The second ratchet part 52 is installed in the pen holder 1, and the deeper positioning groove of the second ratchet part 52 penetrates through. At this time, the stopper 6 can pass through and enter the first ratchet part 51 and the second ratchet part. Work between the tooth parts 52, and by installing the pressing piece 3 on the pen holder 1, it can move up and down without being able to come out. The pressing part 3 is restricted inside the penholder 1 in such a way that the pressing part 3 can move within a certain range inside the penholder 1 at the same time.

[0026] 2. Divide the pen holder 1 into the front rod 11 and the back cover 12, let the first ratchet part 51 be arranged on the front rod 11, and the second ratchet part 52 be arranged on the back cover 12, and at this time first set the stopper 6 And the pressing piece 3 is installed in the front rod 11, abutted by the first ratchet part 51, and then the rear cover 12 is installed, the limiting piece 6...

Abstract

The invention discloses a mute telescopic pen which comprises a penholder, a refill arranged in the penholder, a pressing piece pressed by an arch hand, an elastic component arranged in the penholder and used for providing elastic force for the refill to move towards the tail of the penholder and a positioning mechanism arranged in the penholder, one end of the pressing piece abuts against the refill, and the other end of the pressing piece is used for pressing; the pressing piece is rotatably sleeved with a limiting piece used for being matched with the positioning mechanism, the positioning mechanism comprises a first ratchet part and a second ratchet part which are arranged in the pen holder, a space matched with the limiting piece for positioning is formed between the first ratchet part and the second ratchet part, and the first ratchet part and the second ratchet part are matched with the limiting piece to form a first positioning state and a second positioning state; the pressing piece and the limiting piece slide synchronously. Noise cannot be generated when the pen point stretches out and draws back, and the use condition of a place with the mute requirement is met.

Description

technical field [0001] The invention relates to a writing instrument, in particular to a silent retractable pen. Background technique [0002] The existing push-type retractable pen can be used to protect the nib from being damaged due to bumps. The general push-type retractable pen solution is like the text disclosed in the invention patent of the Chinese patent application number CN201680077875.9 in the prior art. In this structure It cooperates with the ratchet mechanism, the rotating mechanism, the ratchet teeth on the pen holder and the ratchet groove. By pressing down on the ratchet mechanism, the rotating mechanism will produce a certain rotation tendency. When the rotating mechanism comes out of the ratchet groove, it will rotate (at the same time There is a sound of "click" and a momentary collision after the rotation is completed), and then it is stuck in the ratchet teeth to realize positioning and let the nib protrude; when the ratchet mechanism is pressed down a...
