A clamping device has a clamp and a removable handle. A pair of clamping arms is on the clamp. A pivoting device includes a clamp bushing linked with each of the clamping arms of the pair of clamping arms to move the pair of arms between an opened and closed position. The removable handle couples with the clamp bushing. The removable handle includes a release mechanism to actuate the pivot mechanism to move the clamping arms between the open and clamped positions.

The workspace is sufficiently secured while controlling the occupied space. A toggle clamp includes: an actuator capable of linear reciprocating movement of a first shaft; a base plate having an arc-shaped long hole in which the first shaft is slidably fitted; a clamp arm; a base member that rotatably supports the base plate via a second shaft and rotatably supports the clamp arm via a third shaft; and a link member rotatably connected to the clamp arm via a fourth axis and rotatably connected to the base plate via a fifth shaft. In the released state, the fourth shaft is located away from a straight line connecting respective axis centers of the second and fifth shafts. In the fixed state, the fourth shaft is located on a straight line connecting the second and fifth shafts.

A truss setting bracket and a method relating to setting a truss using the truss setting bracket are disclosed herein. In some embodiments, the truss setting bracket includes an elongated body member having a first cradle, a second cradle, an elongated catch guide, and a locking arm. In other embodiments, the truss setting bracket includes an elongated body member having a first cradle, a bracket, an elongated catch guide, and a locking arm. In yet other embodiments, the method of setting the truss may include sliding the truss setting bracket over a member of a first truss, lifting the first truss towards a second truss, and removably locking the truss setting bracket to a member of the second truss.

A clamping system that includes a first jaw, a second jawthe second jaw being pivotally connected to the first jawa locking handle pivotally connected to the first and second jaws, an adjustment element, first and second lever arms, and a release lever secured to the locking handle and configured to move the locking handle away from the first jaw.

An electrical clamping apparatus is provided that can reduce an entire size using a motor as a driving source and largely improve a grip torque by applying a sliding crank portion and a changed toggle link portion with a driving force transfer mechanism. The electrical clamping apparatus for clamping and fixing one side of a panel includes a main body; a driving motor installed within the main body and that generates a driving force; a clamp portion that clamps or unclamps the panel; a toggle link portion connected to the clamp portion and that transfers rotatory power to the clamp portion to rotate the clamp portion; a driving force transfer portion connected to the driving motor to transfer a driving force of the driving motor to the toggle link portion; and a sliding crank portion connected to one side of the toggle link portion to convert a rotational motion of the driving force transfer portion to a linear reciprocating motion and to operate the toggle link portion in a state in which one side thereof is connected to the driving force transfer portion and in which the other side thereof is vertically bent toward the toggle link portion.

A clamping tool is provided which includes a base, a clamping arm articulated to the base for pivotal movement about a first pivot axis, a handle articulated to the clamping arm or base for pivotal movement about a second pivot axis, a bridge element articulated to the handle or the clamping arm for pivotal movement about a third pivot axis, a first wedge element having a first wedge surface, and a second wedge element having a second wedge surface facing towards the first wedge surface. In a first positional range of the handle, the wedge surfaces are spaced apart. In a second positional range of the handle, the second wedge surface is supported on the first wedge surface, displacement of the first wedge element driving a displacement of the second wedge element. The bridge element is articulated to the first wedge element for pivotal movement about a fourth pivot axis.

A method and apparatus for maintaining a fixed distance between two cabinets during installation are provided. An elongated rail with two stops and two clamps are used. The stops are fixed to the elongated rail with opposing faces placed the fixed distance apart. The assembly is placed between the cabinets and a clamp is used to pinch a cabinet wall of each cabinet against a stop. The cabinets are installed and the apparatus is removed. In some embodiments a second apparatus may be used, one at the top of the cabinets and one at the bottom.

A truss setting bracket and a method relating to setting a truss using the truss setting bracket are disclosed herein. In various embodiments the truss setting bracket includes an elongated body member, a first cradle, a second cradle, an elongated catch guide, and a locking arm. The second cradle may include the elongated catch guide on a first finger and the locking arm on a second finger. In various embodiments, the method of setting the truss may include sliding the truss setting bracket over a desired location next to a first truss, lifting the first truss towards a second truss, and removably locking the truss setting bracket to a desired location next to the second truss.
