Curvedly telescopic mechanical arm

Provide is a curvedly telescopic mechanical arm. The telescopic mechanical arm comprises a telescopic arm, wherein the telescopic arm is formed by the pivot connection of two or more scissor structures end to end in series; each scissor structure is formed by the pivot connection of a first connection rod and a second connection rod in a mutually crossed mode; a crossed pivot connection portion is a first pivot connection portion; for each two adjacent scissor structures, the rear portion of the first connection rod of the former scissor structure is in pivot connection with the front portion of the second connection rod of the latter scissor structure; the rear portion of the second connection rod of the former scissor structure is in pivot connection with the front portion of the first connection rod of the latter scissor structure; the first pivot connection portion of each scissor structure divides the connection rods of each scissor structure into front segments and rear segments, wherein the front segment of each first connection rod is longer than the rear segment of the same connection rod, and the front segment of each second connection rod is shorter than the rear segment of the same connection rod. According to the simple structure curvedly telescopic mechanical arm, the application of the scissor structure is improved. Meanwhile, the curvedly telescopic mechanical arm can be folded when not in use, so that the storage space is reduced.
