  • Patent number: 10434587
    Abstract: A miter saw includes a base, a worktable pivotally mounted to the base, a fence mounted at the worktable, an operating handle connected to the worktable, and two opposing supporting units respectively mounted to two opposite sides of the base. Each supporting unit includes a fixed panel and a movable panel pivoted to the fixed panel and biasable between an extended position where the operating handle is stoppable by the fixed panel upon operation to rotate the worktable and a first included angle is defined between a cutting slot and a fence of the worktable and a received position where the operating handle is stoppable by the movable panel upon operation to rotate the worktable and a second included angle larger than the first included angle is defined between the cutting slot and the fence of the worktable. Thus, the miter saw achieves the effect of increasing the miter angle.

  • Patent number: 9375794
    Abstract: A table insert for a circular saw includes a stationary panel and a movable panel. The stationary panel is fixed on a worktable of the circular saw and partially covers a trough of the worktable, and the movable panel is pivotally connected to the stationary panel and is pivotally movable relative to the stationary panel between a first position and a second position. When the movable panel is located in the first position, the movable panel partially covers the trough to enable the cutting operation to be performed. When the movable panel is located in the second position, the trough is partially uncovered for conveniently allowing a user to remove saw dust from the trough or to take out small workpieces that fall into the trough.

  • Publication number: 20150070873
    Abstract: A machine tool with a touch control work lamp includes a machine and a touch control work lamp. The touch control work lamp includes an electrically insulating lamp base disposed on the machine, a connecting member mounted onto the base and extending outwardly from the base, a casing engaged to the connecting member, and a light emitting unit disposed in the casing. By utilizing the touch control work lamp, the machine is prevented from breaking down or malfunctioning, and by using the electrically insulating lamp base, user safety is effectively enhanced.

  • Patent number: RE41320
    Abstract: A miter saw. The saw includes a base on which a scale disk is connected and a bench is rotatably connected on the disk. An angle position device is connected to the bench. Notches are defined in an underside of the scale disk and the angle position device is engaged with one of the notches. A position member is movably connected to the body of the angle position device and a lever is connected to the position member which is pushed to contact a periphery of the scale disk to position the scale disk. A connection member is connected to the bench and a circuit saw assembly is pivotally connected to the connection member. A handle on the circular saw assembly can be pulled out and rotated to adjust an angle thereof.
