Adjustable magnetic control elastic pen

Abstract

The invention relates to the technical field of office appliances and discloses an adjustable magnetic control elastic pen. The adjustable magnetic control elastic pen comprises a rear penholder, a limit ring, a hand-held device, a locking device and a reset device. The outer side of the rear penholder is movably sleeved with the limit ring. Through the cooperation between a semi-magnetic ring anda magnetic member, the adjustable magnetic control elastic pen can utilize the magnetic force generated between the semi-magnetic ring and the magnetic member to offset the elastic force generated bya reset spring and the pressing force generated by the user when writing, when the force applied to a cartridge is greater than the elastic force between the semi-magnetic ring and the magnetic member, the cartridge is retracted into the interior of the penholder, so that the accidental injury from the cartridge to the user are effectively prevented, and a nib of the cartridge can be protected. The attraction of the semi-magnetic ring by the magnetic ring ensures that the position of the cartridge will not change arbitrarily, and improves the stability of the device.

Description

technical field [0001] The invention relates to the technical field of office appliances, in particular to an adjustable magnetically controlled elastic pen. Background technique [0002] The elastic pen is a kind of pen that can elastically contract the refill by using elastic firmware such as springs. This kind of pen can be carried around without using the cap to protect the pen tip, and the refill can be directly retracted into the inside of the pen holder, which is convenient to use , and most of the existing elastic pens use buckles to limit the position of the pen core to overcome the elastic force exerted by the spring on the pen core, but once the buckle breaks, the pen core will not be able to be fixed, thus As a result, the entire pen cannot be used normally, and the pen cap can only be replaced, resulting in a reduction in the service life of the elastic pen, and the tip of the pen core is relatively sharp. The pen core cannot be automatically retracted into the...

[0002] The elastic pen is a kind of pen that can elastically contract the refill by using elastic firmware such as springs. This kind of pen can be carried around without using the cap to protect the pen tip, and the refill can be directly retracted into the inside of the pen holder, which is convenient to use , and most of the existing elastic pens use buckles to limit the position of the pen core to overcome the elastic force exerted by the spring on the pen core, but once the buckle breaks, the pen core will not be able to be fixed, thus As a result, the entire pen cannot be used normally, and the pen cap can only be replaced, resulting in a reduction in the service life of the elastic pen, and the tip of the pen core is relatively sharp. The pen core cannot be automatically retracted into the interior of the pen holder, so accidental injury to the user cannot be avoided

[0003] The pressing pen in the prior art has a complicated structure, and the pen tip cannot avoid hurting people when it is pressed down. In addition, its structure is also complicated and the manufacturing cost is high.
