Portable photovoltaic support convenient to connect

The utility model discloses a portable photovoltaic support convenient for connection, which comprises a connecting piece 1, a movable cavity 1 is arranged in the connecting piece 1, a rotating rod is rotatably arranged in the movable cavity 1, and a thread 1 and a thread 2 are symmetrically arranged on the outer sides of the two ends of the rotating rod. During transportation, the handle is rotated to drive the rotating rod to rotate, and the first sliding block and the second sliding block are driven to move oppositely at the same time, so that the shear fork telescopic frame can be contracted and folded, the first connecting piece and the second connecting piece are close to each other, the size of the shear fork telescopic frame is reduced, and transportation is facilitated; when a handle is rotated to drive a first sliding block and a second sliding block to move oppositely at the same time, a shear fork telescopic frame is unfolded, a first connecting piece and a second connecting piece are far away fro
