发明名称 Fabric clamping device for embroidery machines
摘要 A rectangular molded plastic body includes three heart-shaped clamping portions each of which defines an opening and has resilient inwardly extending arcuate portions terminating in ends spaced from one another. Each arcuate portion carries L-shaped members with upwardly extending conical portions. The outer end of one arcuate portion of each clamping portion has a sloping cam surface thereon which joins with a downwardly facing locking surface, and a handle is also formed on this outer end. Three clamping members are pivotally connected to the body by hinges and are pivotable into and out of the openings of the clamping portions. The clamping members engage the cam surfaces as they pivot into clamping position and are locked in place by the locking surfaces. The clamping members are released by pulling on the handles.
