Pressure-adjustable type elastic pulling out pen

Abstract

The invention relates to a pen, in particular to a pressure-adjustable type elastic pulling out pen. The pressure-adjustable type elastic pulling out pen comprises an assembling inner column, a clamping device, a rear penholder part and a restoring supporting mechanism, wherein a circle of convex matched bulge loop is arranged on the outer surface of the rear end of the assembling inner column, the exterior of the assembling inner column is slidably provided with the clamping device in a sleeved mode, the rear end of the clamping device is in threaded connection with the rear penholder part, and the interior of a front penholder part is movably connected with the restoring supporting mechanism in a sleeving mode. The pressure-adjustable type elastic pulling out pen has the following four technical effects that 1, the anti-shatter effect is added; 2, the writing posture is corrected, so that the situation that fingers are excessively closed to a pen point, the sight is shielded, and the writing is not facilitated is avoided; 3, the retraction and exposure of a pen core can be realized by one hand, so that the switching between the use state and the non-use state are achieved, and when the normal pen holding posture is kept, the switching between the use state and the non-use state can also be realized; and 4, the matching force, that is, the clamping force between the matched bulge loop and a fastening bulge, is adjustable by adjusting the matching degree between the rear pen cylinder internal threads of a rear pen cylinder and the adjusting threads of the clamping device.

technical field

[0001] The invention relates to a pen, in particular to an adjustable pressure type elastic drawing pen. Background technique

[0002] The elastic pull-out pen is a kind of pen that can manually pull out the pen core and reset the pen core by using a spring, so as to realize the effect of retracting freely. When using it, pull out the pen core for normal writing. When using the spring to reset, put the refill into the inside of the pen holder, which is easy to carry around. Most of the existing elastic pens are positioned by pressing the refill and then positioning the refill through the block. Once the force is too large when writing, it will be damaged The pen holder and refill cause damage, which makes the elastic pen unable to be used normally, and some children are just exposed to practice writing, and they cannot grasp the strength of writing well, so it is easy to cause damage to the pen holder and the nib, and the nib of the refill is generally relati...
