A support mechanism includes a fixed body, a rotating unit, a moving unit and a driving unit. The rotating unit is rotationally mounted to the fixed body. The moving unit, disposed at the fixed body, includes a ball screw spline shaft, a ball screw nut and a ball spline nut. The ball screw nut and the ball spline nut are both rotatably disposed at the ball screw spline shaft moved together with the rotating unit. The driving unit, disposed at the fixed body, includes a first driving member and a second driving member to rotate the ball screw nut and the ball spline nut, respectively. With different rotation pairs of the ball screw nut and the ball spline nut to the ball screw spline shaft, the ball screw spline shaft is driven to move, and the ball screw spline shaft is further to move the rotating unit.

An apparatus for partially supporting a vehicle is provided especially for a vehicle having a very limited area on its underside within which to safely apply an upward force, including vehicles with a small distance between the bottom of the chassis and the ground such as a sports car which allows the user to position a lifting jack under the vehicle at the proper access jack point for engagement of the lifting a portion of the vehicle, and lifting the jack and vehicle portion upwardly to a desired height. The legs of the jack stand can be temporarily inserted into a support member engaging the vehicle and the jack. The jack stand includes a horizontal support member with bottom facing open ends telescopically connected to a pair of rigid legs and each of the legs are telescopically attached to supporting bases using locking pins. Once the jack stand is installed, the lifting jack can be removed.

A lifting device includes a guide unit, a support unit and a lifting unit. The guide unit is extendable and retractable along a direction. The support unit is disposed in the guide unit and includes a securing connector fixed to a seat body and made of elastic material, a support tube connected to the securing connector, and a support member disposed on the support tube. The lifting unit includes a first rod-actuating screw member disposed on the support member and having a first threaded hole, and a threaded rod unit including a first threaded rod extending into the support tube and being threadedly engaged with the first threaded hole, such that the first threaded rod is rotatable by an external force and movable in the direction.

Described is an adaptive manufacturing table (100) including a structural frame assembly (300), a moveable table assembly (400) including a table surface (130), and a projector (101) such that the projector (101) is rigidly mounted to the structural frame assembly (300). The projector (101) may be configured to directly project an image onto the table surface (130).

An adjustable wood work bench device (the device) includes a top portion presenting a pair of track parts connected by a connecting element. A pair of jaws wherein the jaw is stationary, and the other jaw is movable from the jaw to the connecting element along the tracks defined in the track parts. Each jaw presents a generally rectangular plate like configuration and define a plurality of holes each of which slidingly accepts a swivelable clamping peg (not shown) to increase the versatility of the device. The connecting member includes elements to secure the device to the tailgate of the truck, or to the standing bench.

A hand-operated planer provided with both a fixed workbench and a lifting mechanism with a locking function is combined with a hand-operated planer, which includes a base, a movable workbench, a fixed workbench and a lifting mechanism. The lifting mechanism is composed of a connecting seat, a position-limiting member, an operating rod and a positioning block. When the handle of the operating rod is moved, the operating rod will actuate the position-limiting block of the position-limiting member to operate and drive the driven plate of the connecting seat to rotate via transmission of the connecting rod and thus, the movable workbench assembled above the axis of the connecting seat can be adjusted in height.
