The force application point of the hand-held pen must not be on the matching inner column or force application ring, preferably on the clamping device, so that normal writing is not influenced, and the technical effect of correcting the writing posture can be achieved.
The using method comprises the following steps:
during the use, will cooperate interior post 102 to contract towards rear pen-holder portion 4 end for the cooperation bulge loop takes place the block with fastening arch 304, and the cooperation bulge loop moves to the other end of fastening arch 304.
When not using, will cooperate the back pen-holder portion 4 end of interior post 102 toward keeping away from to stretch for the cooperation bulge loop takes place to break away from with the block of fastening arch 304, thereby cooperation interior post 102 receives the elasticity of spring, makes cooperation interior post 102 keep away from the refill, thereby makes the nib of refill withdraw in the cooperation interior post 102.
The adjusting mode is as follows: through rotation adjustment, the thread fit distance between the clamping device and the rear barrel part 4 changes the position relationship between the compression ring 307 and the clamping device, so that the compression ring 307 moves in a compression chamber formed between the limiting lantern ring 305 and the fastening extension column 302, the elastic block 306 or the adjusting outer slope 3021 is extruded by the compression ring 307, and if the elastic block 306 or the adjusting outer slope 3021 is extruded by external force, the fastening extension column 302 is forced to deform. The difference between the inner and outer diameters of the fastening projection 304 and the mating male ring can be directly affected. The difference between the inner and outer diameters of the fastening protrusion 304 and the mating collar determines the engaging force between the fastening protrusion 304 and the mating collar.
