资源简介：
A power tool comprising:a rotatable support arrangement for supporting at least one cutting disc and being configured to be rotatably driven by an electric motor;an upper shroud member (120， 20) and a lower shroud member (122， 22) which cooperate to define a volume in which the at least one cutting disc can be supported， the rotatable support arrangement coupled to the upper shroud member (120， 20) such that movement of the upper shroud member (120， 20) towards the lower shroud member (122， 22) causes said at least one cutting disc to protrude through an opening (24， 38) in the lower shroud member (122， 22);biasing means for urging the upper shroud member (120， 20) and the lower shroud member (122， 22) away from each other;a limiting mechanism for limiting the range of movement of the upper shroud member (120， 20) relative to the lower shroud member (122， 22) under action of the biasing means， a first part thereof being carried by the upper shroud member (120， 20) and a second part thereof being carried by the lower shroud member (122， 22); wherein the limiting mechanism can be disengaged by opening (24， 38) the upper shroud member (120， 20) via at least one hinge coupling (25)， thereby increasing the range of relative movement of the upper and lower shroud members (120).
