摘要： The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

摘要： 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.

摘要： A clamp has: a clamping set and a positioning set. The clamping set has a shaft pivotally connected to a first arm and a second arm, and the shaft is provided with an elastic member. The first arm and the second arm are kept open by the elastic member, and the first and second arms are extended downward with a first handle and a second handle. The first handle is provided with a first pin, and the second handle is provided with a second pin. The positioning set is pivoted on a middle section of the first and second handles with the first and second pins. The positioning set is approximately horizontal, and travel distance of the shaft is greatly reduced, which not only reduces the structural cost, but also effectively improves the smoothness of the shaft movement.

摘要： A clamping force visualization device, including a first clamping body (01) for clamping an object; the first clamping body (01) is telescopically assembled on a base (14), an elastic element (110) is provided between the first clamping body (01) and the base (14), and a clamping force scale (11) and a reading indicator (15) are respectively provided on the first clamping body (01) and the base (14); when the first clamping body (01) clamps the object, the elastic element (110) measures a clamping force and the reading indicator (15) points to the clamping force scale (11) for reading, so that the magnitude of the clamping force can be intuitively seen and read during clamping, thereby achieving accurate clamping. A clamp including the clamping force visualization device is also involved.

摘要： A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

摘要： A trigger clamp includes a rail, a movable jaw configured to move along the rail, a handle fixed relative to the movable jaw, and a trigger movable relative to the handle, which when pulled towards the handle causes movement of the movable jaw along the rail. The handle comprises a trigger facing wall generally extending along a first plane, and a fin generally extending to a second plane, the second plane being closer to the trigger than the first plane. The trigger is shaped to be received to an interior of the fin at least when the trigger is squeezed by a hand of a user, such that an index finger of the user remains at the exterior of the fin. Methods of manufacturing and using similar trigger clamps are also disclosed.
