Workpiece securement systems for securing a workpiece in a desired position with a clamp. The workpiece securement systems include a worktable, an anchor, a shelf, and a block. A tabletop of the worktable defines a plurality of shaped openings. The anchor is disposed in a selected shaped opening and is configured to engage a bolt. The shelf is configured to support the anchor from below the tabletop in a position where the anchor extends through the selected shaped opening. The block is supported on the tabletop and selectively couples with the anchor. The block defines a mount bore and a clamp receiver bore. The bolt passing through the mount bore and engaging with the anchor secures the position of the block on the tabletop. The clamp receiver bore is configured to receive the clamp to fix the position of the workpiece.

A supplementary support assembly for a workpiece support assembly of a semi-stationary machine tool, wherein a workpiece support body of the workpiece support assembly has a base supporting surface, which is substantially horizontal in use, for supporting a workpiece for sawing by a tool of the machine tool, wherein the supplementary support assembly has a supplementary supporting surface and a support body with support body mounting means for detachably mounting on the workpiece support assembly, wherein when the supplementary support assembly is mounted on the workpiece support assembly the supplementary supporting surface is at least substantially aligned with the base supporting surface.

A hybrid clamp is configurable as a bar clamp or a dog clamp, where first and second clamp members may be associated with a clamp bar or may be separated and connected to other supports for use as dog clamps. A clamping sawhorse is configured to mount the hybrid clamp for use as a bar clamp or as a dog clamp in conjunction with the sawhorse, such as including apertures for accepting either the clamp bar or mounting portions of the first and second clamps.

The invention discloses a workbench, comprising: a folding base comprising a left support frame and a right support frame cross connected with each other by a pivot and a handle rod connected with tops of the left support frame and the right support frame; a movable plate fixed on the left support frame and provided with at least one first fixing hole; a fixed plate fixed on the right support frame and provided with at least one second fixing hole; the movable plate and the fixed plate are spread out on the upper surface of the folding base as the left support frame and right support frame are unfolded; and the movable plate and the fixed plate are folded downwards along both sides of the handle rod as the left support frame and the right support frame are furled. The present invention allows the workbench to be folded by folding downwards the movable plate and the fixed plate, such that the workbench occupies less space and the folded workbench is more secure. The additional first fixing hole and second fixing hole on the workbench effectively stabilize workpieces.

A hinge mechanism with a collapsible leg is disclosed. The hinge mechanism may include a support member with a first end and a second end. The first end may be configured to be rotationally coupled to a first portion of a frame via a first rotational coupling. The second end may be rotationally coupled to the collapsible leg via a second rotational coupling. The collapsible leg may be configured to move between an extended position and a collapsed position. The collapsible leg may include a mating surface at a first leg end. The mating surface may be configured to be removably mateable to a corresponding mating surface of a second portion of the frame when in the extended position.

The present invention adopts an overlap-type supporting and fixing structure for painting, which includes a support frame, and a fixed end is located on the top of such support frame for the purpose of bolting, while an embedding trough structure is established on its bottom to allow the bolt fixed end to be completed embedded into it; The bottom of the right half part of the front end of the support frame is provided with a first embedding tooth structure which has a continuous toothlike structure, and the top of the first embedding tooth structure is equipped with a first embedding trough structure which matches the shape of the first embedding tooth structure and allows the first embedding tooth structure to be exactly embedded into it; When the up-down overlapping has been realized between one support frame and another identical support frame, the connecting embedding trough of the upper support frame will be embedded into the connecting seat of the lower support frame; Meanwhile, the first embedding tooth structure of the upper support frame will be embedded into the first embedding trough structure of the lower support frame, and the second embedding tooth structure of the upper support frame will be embedded into the second embedding trough structure, The present invention adopts an overlap-type supporting and fixing structure, whereby the door panel can be rotated conveniently after fixation, and multiple door panels can be air-cured and stored by way of superimposition.
