Elevation mechanisms for table saws and anti-backdrive mechanisms for use in elevation mechanisms for table saws are disclosed. The anti-backdrive mechanisms typically include three sub-assemblies: an input assembly, an output assembly, and a fixed assembly. The anti-backdrive mechanisms prevent a torque related to the output assembly from changing the blade elevation. For example, the weight of the blade and the structure supporting the blade is prevented from backdriving the elevation mechanism and allowing the blade to drop.

The safe and efficient cutting of window blinds can be accomplished by utilizing a blind cutting system which is configured to support and contain the blinds in a desired position, and to have a cutting saw move along a cutting plane such that a cutting blade will interact with the blinds and cut a predetermined portion from an end thereof. A framework is used to support the cutting saw and allow movement of a cutting blade in a very controlled manner, thus avoiding any possibility that the blade is positioned in a dangerous position during operation. Further, the travel of the cutting blade along a cutting path will create a cutting action in a controlled and defined manner. Further, the cutting blade is shielded on virtually all sides, thus eliminating the possibility of injury or harm to a user. 1. A blind cutting system for customizing window blinds , comprising:A framework;a pair of substantially parallel rails attached to the framework and oriented in a near vertical position during operation of the blind cutting device;a cutting saw slidably coupled to the pair of rails, the cutting saw having a cutting blade which is movable along a cutting path, which is contained within a portion of a cutting plane, when the saw is moved along the pair of rails, wherein the cutting plane is also substantially parallel to the pair of rails;a holding structure coupled to the frame and positioned in predetermined position relative to the pair of rails, the holding structure comprising an adjustable support shelf, a slidable holding clamp, and a slidable registration stop, wherein the adjustable support shelf is capable of being sized to support the blinds to be cut and has supporting surface which is and normal to the cutting plane, wherein the slidable holding clamp has a clamp surface substantially parallel to the supporting surface which is movable in a direction normal to the clamp surface and the supporting surface, and wherein the slidable registration stop has a stop ...

A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved. 1. A cutting device for tabletop or stationary use , comprising:a table configured to receive a material to be cut;a cutting device main body moveably attached to the table, the cutting device main body including a cutting blade aligned in a cutting direction; anda battery structured to be attached to the cutting device main body in a sliding direction,wherein the sliding direction of the battery is non-parallel to the cutting direction of the cutting blade.2.

A table saw hold-down device comprising a straight edge located on a horizontal planar surface, wherein the horizontal planar surface includes a table saw. The straight edge includes a flat surface against which an item is placed when being cut by the table saw, and wherein the flat surface is perpendicular to the horizontal planar surface. Two or more wheels are movably coupled to the straight edge and are configured such that when said item is placed against the flat surface of the straight edge when being cut, and the wheels contact said item, the wheels rotate to accommodate movement of said item along the straight edge. At least one spring loaded mechanism coupled to the wheels is configured for moving the wheels down such that when said item is placed against the straight edge when being cut, the spring loaded mechanism pushes the wheels against said item. 1.

A compound saw includes a base, a housing, a transmission component and a table, the rear end of the table is rotatably connected to the housing, and is engaged with the cutter head through the transmission component, so as to expose the cutter head out of the first cutting slit or out of the second cutting slit when the front end of the table swings upward and downward. The cutter head of the compound saw can be switched between the bench cutting mode and the miter cutting mode. Accordingly, on one hand, the structure for switching between modes is simple and does not require the cooperation of too many parts; on the other hand, the switchover can be realized simply by manually operating the movable bench, without too many operations.
