Boring fixing clamp of telescopic oil cylinder

The boring fixing clamp of the telescopic oil cylinder comprises a clamping component, the clamping component comprises a rotary adjusting assembly, a telescopic clamping assembly is arranged on the rotary adjusting assembly, and an installation assembly is arranged below the rotary adjusting assembly. And the rotary adjusting assembly comprises a vertical plate, a hydraulic rod, a fixing ring and four connecting rods, one end of the vertical plate is rotationally connected to the other end of the hydraulic rod, the driving end of the hydraulic rod is fixedly connected to the outer wall of the fixing ring, the number of the connecting rods is four, and the outer wall of one connecting rod is arranged on the inner wall of the fixing ring. According to the boring fixing clamp of the telescopic oil cylinder, the clamping range and length can be enlarged when the cylinder barrel of the telescopic oil cylinder is clamped, so that the clamping is firmer and firmer, shaking during boring is prevented, and the boring
