A table saw includes a worktable, a left extension frame and a right extension frame respectively slidably mounted at left and right sides of the worktable, a scale unit including a first scale, a second scale and a third scale respectively mounted at the worktable, the left extension frame and the right extension frame, and an indicator unit including a first indicator, a second indicator and a third indicator respectively disposed to aim at the first, second and third scales. Thus, when operating the table saw to cut a workpiece, the user can selectively pull out the left or right extension frame and use the corresponding scale and indicator for quickly judging the correctness of the length to be cut.

A slidable workbench includes a shifting mechanism and a push member. The shifting mechanism includes a fixed board, two slide rails, and a sliding platform. Immovable sections of the slide rails are disposed on the top surface of the fixed board and spaced at an interval. Movable sections of the slide rails are disposed at the bottom surface of the sliding platform, enabling the sliding platform to slide on the fixed board through the slide rails. Thereby, a workpiece is pushed by the push member and the sliding platform is slidable relative to the fixed board for the user to operate a table saw in a quick, labor-saving and easy manner. The slidable workbench can be used for all kinds of saw machines to enhance the convenience and safety of the saw machines greatly and improve the quality of cutting.

A sliding table type circular sawing machine includes a housing having one side assembled with a travelling mechanism and its interior provided with a first fixed seat, a second fixed seat and a third fixed seat spaced apart. A power mechanism is received in the housing and a circular saw blade protrudes out of the topside of the housing. The power mechanism is respectively connected with the second fixed seat and the circular saw blade so that a short distance can be maintained between the extreme and of the power mechanism and the circular saw blade. Thus, cooperating with the travelling mechanism that is able to quickly position a work piece, the sliding table type circular sawing machine of this invention is able to carry out successive sawing operation with quickness, with less labor and with simplicity, thus enhancing convenience of the sliding table type circular sawing machine.

A table saw has a base assembly, a table assembly supported by the base assembly, the table assembly, and a saw assembly supported by at least one of the table assembly and the base assembly. The saw assembly has a saw blade extending through the table assembly. The base assembly has at least one foot having a substantially horizontal surface, a substantially vertical surface, and a curved surface disposed between the substantially horizontal surface and the substantially vertical surface. The substantially vertical surface is substantially coplanar with a surface of the table assembly so that the table saw can be disposed on the substantially vertical surface and the surface of the table assembly.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

A table saw includes a frame; a saw having a cutting blade supported by the frame; first and second rails extending along opposite sides of the frame; a table supported by the frame; and a fence extending across the table between the first and second rail. A fence holder removably secures the fence to the first rail. The fence holder has a housing and an alignment arrangement configured to balance opposing forces between the fence holder housing and the first rail to hold the fence in a fixed angle relative to the first and second rails.

The invention relates to a method of remote control of a portable automated cutter comprising a power cutter. The position of the power cutter is controlled by a controller based at least partly on input provided by a user via an intelligent measuring tape. The intelligent measuring tape comprising a distance sensor, an orientation sensor, a micro-controller and a user interface comprising a communication element. The user is extracting tape from the intelligent measuring tape enclosure along at least one part of a representation of a cutting off, the distance sensor establishing a linear measure of the length of the extracted tape, by activating the communication element, the user facilitates wireless communication of the established linear measure from the micro-controller to the controller, and upon receiving the linear measure, the controller controls the power cutter according to the established linear measure.
