Abstract: A hole saw component combinable with a saw blade detachably comprises an arbor assembly and a holder. The arbor assembly comprises a collar, a shank part, a movable member and at least one drive pin. The shank part is connected with the collar and comprises a plurality of positioning grooves. The movable member is sleeved on the shank part and is movable between different positioning grooves relative to the shank part. The drive pin is connected with and moved with the movable member. The holder forms a detachable engagement structure with the collar. When the movable member moves to different positioning grooves relative to the shank part, a combination status of the holder and/or the saw blade is changeable by moving the drive pin with the movable member, such that the arbor assembly or/and the saw blade is separable from or combinable with the holder.

Abstract: A grip structure includes a grip base and a grip mounted with or dismounted from the grip base along a first direction. When being disposed on the grip base, the grip can be applied with an external force to move together with the grip base along a second direction non-parallel to the first direction. The grip has a finger abutting portion formed on the circumferential surface of the grip along the first direction for the fingers of the user to be abutted thereon. Therefore, the grip is changeable in the direction relative to the grip base according to the dominant hand of the user in a way that the finger abutting portion is toward the left side of the grip base for the right-handed user and toward the right side of the grip base for the left-handed user, thereby improved in the convenience of usage and hand feel.

Abstract: A telescopic pipe structure for a pole saw includes an inner pipe, an outer pipe fitted to the inner pipe and moving relative to the inner pipe, and an adjusting device. The adjusting device includes a body, a pressing unit, and an adjusting unit. The outer pipe is penetratingly disposed at a sleeve hole of the body. The pressing unit is pivotally disposed a pressing portion of the body to press against inner pipe and stop movement of the inner pipe. The adjusting unit is disposed at a positioning portion of the body and has a driving element and a positioning element driven by the driving element. The driving element can be at first and second positions, and thus the positioning element moves in one and another directions of the sleeve hole, so as to enable and disable the positioning of the outer and inner pipes, respectively.
