摘要 Sucker rod guide clamping devices which in a first embodiment include a scissor clamping device provided with a pair of pivotally-disposed clamping jaws pivotally attached to corresponding pivoting jaw arms. One of the clamping jaws is provided with a projecting plate for engaging a sucker rod and the oppositely-disposed clamping jaw includes a pair of engaging flanges for receiving and seating a slotted sucker rod guide, wherein the sucker rod guide is installed on the sucker rod by pressure applied to the jaw arms. In a second embodiment a piston clamping device includes a C-shaped frame, in which is mounted a fluid cylinder, with a pair of engaging flanges provided in the frame for receiving a sucker rod guide and a fluid cylinder piston adapted to engage a sucker rod.
