Abstract: A clamp contains: a body, an actuation rod, and a slow descending device. The body includes a first support sheet, and the actuation rod includes a second support sheet. The body further includes a drive grip, a driven mechanism, and a limitation mechanism. The limitation mechanism has a first spring, multiple first fixing protrusions, and a release lever. The slow descending device includes a second spring, multiple second fixing protrusions, a guide element, and a micro-adjustment handle. The micro-adjustment handle has a pull lever and the second spring 31 surrounds around the actuation ro. The multiple second fixing protrusions accommodate the actuation rod and are pushed by the second spring. The micro-adjustment handle has a third spring and a control lever pushed by the third spring and contacting with the multiple second fixing protrusions.

Abstract: A clamp contains: a first clamping assembly, a second clamping assembly, and a guide shaft. The first clamping assembly includes a base, a first clamper, a first connection member, and a first buffer. The base has a grip, an operation lever, and a release lever. The base further includes a release structure driven by the release lever to remove the base from the guide shaft. The second clamping assembly includes a second clamper, a second connection member, and a second buffer. The first buffer accommodates the guide shaft, and the second buffer is fitted on and is rotated with respect to an outer wall of the second connection member. The second clamper is fitted on the second buffer and the second connection member, the second clamper is rotatable relative to the second connection member, and the second clamper and the second buffer are connected with the second connection member.

Abstract: A vise is provided with a movable jaw including a threaded hole in a channel; an actuator in the channel and having a hole through an arcuate surface; a limit member in the channel and having front and intermediate cavities and a rear groove; a first plate member in the front cavity and having a through hole; a third plate member in the intermediate cavity and having a through hole; and a second plate member sandwiched between the first plate member and the third plate member and having a hole through a convex surface; and a slide sleeve including a tunnel, an intermediate thread engaging the threaded hole, a front annular flange in the rear groove, a front recess surrounded by the annular flange, and a biasing member in the front recess and urging against the third plate member; a handle; and a stationary jaw including a slide bar.

Abstract: A supporter for a woodworking table contains: four supporting rods, four driving columns, and two movable adjustment posts. Two middle sections of two of the four driving columns are rotatably connected with two middle sections of the other two of the four driving columns respectively, and one side of each of the four supporting rods is in connection with each of two ends of each driving column. The two movable adjustment posts parallelly correspond to each other, and each end of each of the two movable adjustment posts is rotatably connected with a middle section of each supporting rod. Each movable adjustment post includes an outer tube, an inner tube, and an adjustable stem. Thereby, the supporter of the present invention is collapsible so as to decrease its storage size. The supporter adjustably supports the table board based on a size of the table board.
