Abstract
A writing instrument compressing device includes a base having an underside mounted to multiple raiser pieces to have the base separate from a carrying surface by a distance in a vertical direction. The base includes an elongate hole that is delimited by two opposite sidewalls each including tooth ridges and the tooth troughs alternately arranged. A handle rod is pivoted to an end of the base to drive reciprocal movement of a pusher. A retainer is reciprocally movable along the elongate hole of the base and functions to clamp and fix a writing instrument body or a tool. The retainer is provided, on a bottom thereof, with a screw rod extending through the elongate hole of the base. A tightening assembly includes a nut and a rotation bar horizontally penetrating through the nut and having two ends selectively moved close to the nut.
