Abstract
A material-saving and energy-saving multifunctional bench clamp includes a movable clamp body, a fixed clamp body and a transmission pair of a screw and a nut. The fixed clamp body is provided with a holding accessory and a retractable locating-guiding device. The movable clamp body is made up of a left part and a right part. The left part is provided with two work heads, each head includes holding members, which form a holding assembly together with the accessories installed on the fixed clamp body. At least two axially locating-guiding key grooves are shaped on the cylinder guide rail of the right part and positioned the corresponding work heads of the left part. The bench clamp not only reduces processing surfaces and costs, but also saves about 30% material of clamper body under the same standard size and rated clamp force by comparison to the old multifunctional bench clamp.
