A power tool comprising: a housing; a handle having two ends, the first end being moveably mounted to the housing via a first mounting assembly, the second end being moveably mounted to the housing via a second mounting assembly; a biasing mechanism connected between the housing and the handle; wherein at least one of the mounting assemblies (36, 34) comprises: a first part mounted on the housing and a second part mounted on the one end of the handle, one part comprising a support, the other part comprising a pin, having a longitudinal axis, located in the support which is capable of being rotated in the support to enable the end of the handle to rotate relative to the housing and to move linearly in the support to enable the end of the handle to move linearly relative to the housing; wherein the support comprises a passage in which the pin is located; wherein the passage has a cross section which is substantially uniform in shape along the length of the passage, which cross section has a shape with a length larger in a first direction than a width smaller in a second perpendicular direction, the pin being capable of freely moving within the passage either rotationally about its axis to enable the end of the handle to rotate relative to the housing or linearly in a direction of the larger length to enable the end of the handle to move linearly relative to the housing; characterised in that the size of the width varies along the length of the passage to provide at least one curved convex surface along at least part of the length of the passage which is capable of being engaged by the side of the pin to enable the pin to pivot within the passage about an axis parallel to the direction of the larger length. a housing; a handle having two ends, the first end being moveably mounted to the housing via a first mounting assembly, the second end being moveably mounted to the housing via a second mounting assembly; a biasing mechanism connected between the housing and the handle; wherein at least one of the mounting assemblies (36, 34) comprises: a first part mounted on the housing and a second part mounted on the one end of the handle, one part comprising a support, the other part comprising a pin, having a longitudinal axis, located in the support which is capable of being rotated in the support to enable the end of the handle to rotate relative to the housing and to move linearly in the support to enable the end of the handle to move linearly relative to the housing; wherein the support comprises a passage in which the pin is located; wherein the passage has a cross section which is substantially uniform in shape along the length of the passage, which cross section has a shape with a length larger in a first direction than a width smaller in a second perpendicular direction, the pin being capable of freely moving within the passage either rotationally about its axis to enable the end of the handle to rotate relative to the housing or linearly in a direction of the larger length to enable the end of the handle to move linearly relative to the housing; characterised in that the size of the width varies along the length of the passage to provide at least one curved convex surface along at least part of the length of the passage which is capable of being engaged by the side of the pin to enable the pin to pivot within the passage about an axis parallel to the direction of the larger length. a first part mounted on the housing and a second part mounted on the one end of the handle, one part comprising a support, the other part comprising a pin, having a longitudinal axis, located in the support which is capable of being rotated in the support to enable the end of the handle to rotate relative to the housing and to move linearly in the support to enable the end of the handle to move linearly relative to the housing; wherein the support comprises a passage in which the pin is located; wherein the passage has a cross section which is substantially uniform in shape along the length of the passage, which cross section has a shape with a length larger in a first direction than a width smaller in a second perpendicular direction, the pin being capable of freely moving within the passage either rotationally about its axis to enable the end of the handle to rotate relative to the housing or linearly in a direction of the larger length to enable the end of the handle to move linearly relative to the housing; characterised in that the size of the width varies along the length of the passage to provide at least one curved convex surface along at least part of the length of the passage which is capable of being engaged by the side of the pin to enable the pin to pivot within the passage about an axis parallel to the direction of the larger length.
