    摘要: An improved dust collector is proposed. The dust collector comprises an upper duct, and a flexible lower flap connected to the upper dust duct, wherein the lower flap is resilient. Preferably, the upper duct has a substantially U-shaped cross-section, whereas the bottom of the duct is open. The lower flap is disposed in the open portion of the inlet. Furthermore, the upper duct inlet and outlet may have corresponding centerlines, whereas the centerline of the upper duct outlet may be offset from the centerline of the upper duct inlet by a predetermined number of degrees, e.g., about 15°. In addition, the dust collector may further include a wire for maintaining the lower flap in an open position.

    摘要: A power tool can include a gear case, a motor having first and second sets of lead wires, a housing assembly, and a field case. The field case may include a front portion configured for engaging the gear case and a rear portion. The housing assembly may include first and second generally symmetrical housing segments configured for engaging the field case and forming a mid-handle grip. The first set of lead wires may be routed through the front portion of the field case directly to a trigger switch assembly. A method for assembling a mid-handle power tool is also provided and may include routing lead wires through a ventilation path between the field case and trigger assembly.
