Abstract: A mobile power tool stand includes two transverse bars for holding a power tool thereon, two first legs respectively pivoted to the transverse bars, two links respectively pivoted to the transverse bars, two second legs respectively pivoted to the first legs and the links for allowing the mobile power tool stand to be set between a received status where the first legs and the second legs are received together, and an extended status where the bottom ends of the first and second legs support the whole structure of the stand on the floor, and a locking structure for selectively locking the mobile power tool stand between the received status and the extended status.

Abstract: For mounting on the beam of a mobile stand to hold a machine, a bracket assembly includes a bracket body supportable on the beam of the mobile stand, a front clamp mounted in the bracket body and clamped on the beam of the stand, a rear clamp pivoted to the bracket body, and a locking control device pivotally mounted in the bracket body for operation by the user to impart a biasing force to the rear clamp for enabling the rear claim firmly clamped on the beam of the stand so as to further hold down the machine on the beam between the front clamp and the rear clamp.

Abstract: A table saw includes two guide bars movable along two opposite sides of a worktable to carry a table extension, and a locking mechanism for locking the guide bars in position. The locking mechanism includes a handle pivoted to a coupling block at the bottom side of the worktable, two eccentric members reversely mounted in the handle, and two links respectively coupled between the eccentric members and the guide bars and movable with the handle to force a respective stop block against or to release the respective stop block from the guide bars to further lock or unlock the guide bars and the table extension.

Abstract: A table saw includes a table, a saw unit coupled to a substantially inverted U-shaped suspension girder, two supporting devices fixedly fastened to the bottom side of the table to support the suspension girder, and two sliding blocks respectively fastened to the two ends of the suspension girder and respectively coupled to a respective arched guide slot in each of the supporting devices to guide movement of the suspension girder along an arched track to keep the cutting reference point of the saw blade in position so that the saw blade can cut the workpiece accurately.

Abstract: A saw blade adjustment structure used in a table saw for correcting the position of a saw blade of a saw unit includes a supporting member provided below the bottom side of the table of the table saw to support the saw unit of the table saw, and an adjustment device, which includes a driven member connected to the supporting member and a rotating member that has an eccentric portion for moving the driven member to correct the position of the saw blade upon rotation of the rotating member by an external rotary driving force.

Abstract: A worktable includes two first rails arranged in parallel on a base, two guide rods movable along the first rails in a first direction and a second direction reversed to the first direction, two second rails respectively slidably coupled to the guide rods, a sliding plate fixedly mounted on the second rails, and a positioning device for locking the sliding plate to stop the sliding plate from movement relative to the base.
