Abstract

The invention relates to pens, in particular to an anti-drop pen. The anti-drop pen comprises a pen holder, a supporting tail tube, an adjusting inner rod, a reset spring, a pen refill and a pressingsleeve. The supporting tail tube is of a hollow inner tube structure, and the front portion and the rear portion of the supporting tail tube communicate in a front-back mode. One or more supporting fixed rods slantly extend from the middle portion, facing the axis of the supporting tail tube, of the interior of the tube. The internal space of the supporting tail tube is divided into a using cavityand a standing cavity with the supporting fixed rods as the boundary. The adjusting inner rod is of a rod body structure, the front end of the adjusting inner rod is provided with an adjusting ring platform, and the other end of the adjusting inner rod is provided with an abutting platform. The front end of the adjusting ring platform is further provides a fixed platform. The fixed platform is mounted and sleeved with the supporting tail tube. The tail end of the fixed platform penetrates through the supporting tail tube. The fixed platform is matched with the pressing sleeve through threadsor buckles. The pressing sleeve is movably arranged in the supporting tail tube in an expansion mode. A supporting guide slope is arranged in the position, close to the tail end side, of the adjustingring platform, and a damping slope is arranged in the position, close to the front end side, of the adjusting ring platform. The pen refill is arranged in the pen holder. The fixed platform is further provided with a pen refill containing cavity. The tail end of the pen refill is sleeved with the pen refill fixing containing cavity.

Description

technical field [0001] The invention relates to a pen, in particular to an anti-drop pen. Background technique [0002] Most of the pens on the market today are not drop-resistant. Even if they are drop-resistant, their protective structures are extremely complicated and cannot be popularized on a large scale so that everyone can use them. After all, falling from a desk is a rare event; if the cost If it is too high, then this small probability event is also a waste in terms of cost and resources; although the quality of the existing refill continues to improve, but it can still be anti-fall when it is installed in the pen case, then The actual cost will be too high; the loss outweighs the gain; [0003] However, if the anti-drop problem is not optimized, after the pen is dropped, the refill will be damaged, and there will be many more damaged refills. This is a kind of pressure on the environment, because it causes unnecessary damage. waste of [0004] And how to quickly...
