Abstract: A wire locking mechanism (200, 300, 400, 500, 600, 700) for a reinforcement bar, rebar, wire tying device (100), the locking mechanism comprising (200, 300, 400, 500, 600, 700) a holding member (210, 310) and a counter-holding member (220, 320) arranged to engage respective and opposite sides of a wire (230) to releasably hold the wire (230) in a locking position, where a holding force exerted on the wire (230) by the holding member (210, 310) is normal to a holding plane (A2), wherein the holding member (210, 310) is supported on a first end of an excentre arm (240, 340), the excentre arm (240, 340) being rotatably supported on a first shaft (250, 350) to rotate (R1) about an excentre arm center of rotation (255, 355), wherein the holding member (210, 310) is arranged distanced (D) along a first axis (A1) from the excentre arm center of rotation (255, 355), the first axis (A1) forming an acute angle (A) with the holding plane (A2) when in the locking position.

Abstract: A battery compartment battery lock mechanism (700) comprising a locking member (710) rotatably supported on a shaft (720) and comprising a leading edge portion (750) arranged to enter a recess (760) formed in a battery (220) to lock the battery in position, The leading edge portion (750) has an arcuate form with a curvature corresponding to that of a circle segment with radius corresponding to the distance from the leading edge portion (750) to the center of the shaft (720) The recess (760) formed in the battery (220) comprises a surface (770) arranged to engage the leading edge portion (750), wherein the surface (770) has an arcuate form to match that of the leading edge portion (750). The invention further comprises an electrically powered hand-held work tool comprising such a battery lock mechanism.

Abstract: A hand-held work tool (100) comprising a first part (110) and a second part (120) arranged vibrationally isolated from each other, the first part (110) comprising an interface for holding a circular cutting tool (130) and an electric motor (140) arranged to drive the circular cutting tool, wherein the electric motor (140) is arranged to drive a fan (145) configured to generate a flow of cooling air for cooling the electric motor (140), the second part (120) comprising a battery compartment (150) for holding an electrical storage device arranged to power the electric motor (140), wherein a cooling air conduit is arranged to guide a portion of the flow of cooling air (160) from the first part (110) and into the second part (120) for cooling the electrical storage device.

Abstract: A battery (1800) for insertion into a battery compartment (150) of a hand-held work tool (100, 200), wherein the battery (1800) has a weight between 3-7 kg, and comprises a groove (1810) arranged on one side of the battery to mate with a corresponding supporting heel (1710) arranged on a wall of a battery compartment (150). The battery further comprises an upper ridge structure (1820) and a lower ridge structure (1830) arranged on an opposite side of the battery compared to the groove (1810), wherein the ridge structures (1820, 1830) are arranged to mate with corresponding dove-tail grooves (1720, 1730) of the battery compartment (150).

Abstract: The present disclosure relates to a cutter clamp (8, 37) that comprises a first arm part (10, 39) and a second arm part (11, 40), where the arm parts (10, 11; 39, 40) are arcuate and arranged to adjustably at least partially enclose a major part of a circumference (57, 63) having a center (58, 64). The cutter clamp (8, 37) comprises at least one hollow rod (21, 22; 48, 62) arranged for receiving a mounting rod (36) for a power cutter (1, 56) in a pivoting manner. The smaller circumference the arm parts (10, 11; 39, 40) are adjusted for, the closer to the center (58, 64) said hollow rod (21, 22; 48, 62) is moved. The present disclosure also relates to a cutter clamp attachment device (68), a cutter clamp kit and a cutter clamp holding frame (76).
