Counter pen for protecting refill

Abstract

The invention discloses a counter pen for protecting a refill. The counter pen comprises a supporting platform, the bottom face of the supporting platform is provided with a cylindrical slot, the cylindrical slot is internally provided with an end head, the end head is of a cavity structure and is internally provided with a sliding block, the sliding block can move up and down relative to the endhead, the bottom face of the sliding block is connected with the tail portion of the refill, the end head is connected with a pen holder, the pen holder is internally and fixedly provided with a fixedplate, the refill penetrates through a through hole arranged in the fixed plate, a tension spring is arranged between the fixed plate and the sliding block and applies a downward first tensile forceon the sliding block, and the sliding block is further subjected to a second tensile force in the opposite direction with the first tensile force, and the inner wall of the end head is provided with aposition-limiting device used for fixing the sliding block. According to the counter pen for protecting the refill, when the pen holder is pulled downwards, the refill arranged inside the pen holderwill expose a pen point, when the counter pen is used and after the pen holder is loosened, the first tensile force is less than the second tensile force, the refill will retreat into the pen holder,a refill head is effectively protected, in this way, waste of the refill is avoided, and resources are effectively utilized.
