The utility model belongs to the technical field of the mounting technique of preformed helical gold utensil and specifically relates to a ware twists in advance is related to. This ware twists in advance includes handle spare, extensible member, pressure connectors and keeps out the piece, the one end of extensible member with pressure connectors connects, the other end of extensible member withhandle spare movably connects, pressure connectors is last to have a first arc structure the both sides of first arc structure are provided with hank strip jack in advance, keep out have on the piecewith first arc structure corresponds complex second arc structure, the extensible member is in the removal of stretching out and drawing back under the drive of handle spare, so that first arc structure leaves the motion with second arc structure relatively or mutually. The utility model provides a technical problem of the bare -handed installation preformed helical gold utensil difficulty that exists among the prior art, simple structure, convenient operation.
