Novel injection head support frame fine adjustment mechanism

The utility model belongs to the technical field of continuous tubing operation machines and particularly relates to a novel injection head support frame fine adjustment mechanism used for a ground support structure between an injection head and a blowout preventing device. The novel injection head support frame fine adjustment mechanism comprises a mechanism bottom, and a mechanism top used for ejecting a support frame bottom on the injection head support frame, wherein the mechanism bottom can be fixed on a lower support frame of the injection head support frame; a lifting device capable of lifting the mechanism top is connected between the mechanism top and the mechanism bottom. The purpose of the utility model is to provide the novel injection head support frame fine adjustment mechanism which can perform fine adjustment on the lifting stride of the injection head support frame.
