摘要： A pole saw is provided which allows a saw blade to be manually attached or detached in a simple and easy manner. The pole saw includes the saw blade (10), a long handle (20) provided with one or more stages of poles, and a connecting bracket (30) for attaching the saw blade (10) to the distal end of the long handle (20). The pole saw is configured such that the connection and disconnection between the connecting bracket (30) and the long handle (20) are effected by a combination of pin locking and screw locking, the pin locking being effected by a spring-biased latching pin (40), the screw locking being effected by a dedicated hand screw (50) having a grip head (51).

摘要： A saw sheath is provided which allows a saw to be inserted easily and smoothly, which prevents the inserted saw from easily falling out or rattling in the sheath, and which can suppress scraping-off of the inner wall by the blade tip of the saw blade caught by the inner wall. The saw sheath (1) includes a flat sheath opening section (10) and a flat main sheath body (20), and a saw blade (31) is inserted into the main sheath body (20) via the sheath opening section (10). The sheath opening section (10) has an opening width that is wider at the entrance and becomes narrower with depth. A pair of guide rollers (11a) are provided at the entrance of the sheath opening section (10), on the respective sides in the width direction of the entrance, and a pair of grip penetration preventing sections (15) are provided behind the pair of guide rollers (11a). Certain spacing between the grip penetration preventing section (15) and the corresponding guide roller (11a) constitutes an elastic grip-fitting space (16).
