1. Elastic gathered automatically centering panel clamping mechanical fingers for a vascular intervention, comprising a left clamping panel, a right clamping panel, left gathering pieces, right gathering pieces, a linear-propelling mechanism, and a frame, wherein
the linear-propelling mechanism is arranged on the frame;
the left clamping panel and the right clamping panel are oppositely arranged, and the left clamping panel and the right clamping panel are each arranged on the linear-propelling mechanism;
the left gathering pieces are arranged on the left clamping panel, and the right gathering pieces are arranged on the right clamping panel; and
the linear-propelling mechanism drives the left clamping panel and the right clamping panel to move towards each other, or the linear-propelling mechanism drives the left clamping panel and the right clamping panel to move away from each other,
wherein the linear-propelling mechanism comprises position-limiting guiding rails, adjusting screw rods, and moving assemblies, and wherein
each of the moving assemblies is provided with position-limiting holes and spiral holes; an axial direction of each of the position-limiting holes and an axial direction of each of the spiral holes is the same;
each of the position-limiting guiding rails is arranged in the position-limiting holes, and each of the adjusting screw rods is arranged in the spiral holes;
each of the adjusting screw rods drives each of the moving assemblies to move reciprocally on each of the position-limiting guiding rails by a rotating motion.
