[0032] Working process: When the device is in use, the external power supply is powered on, the components are placed at the front end position of the first extrusion block 53, and the motor 2 is started. The motor 2 drives the conveyor belt 4 to rotate through the roller 3, and the clamping assembly 7 and the buffer assembly 6 arranged on the outside of the conveyor belt 4 move. When the slope block 73 moves, the slope block 73 contacts the first extrusion block 53.

The vertical plate 61 is divided into two pieces to facilitate the rotation of the conveyor belt 4. The push rod 65 pushes the clamping plate 71 to move, and the clamping plate 71 drives the rubber ball 74 to clamp the component body 8, thereby fixing the component body 8 to prevent the component body 8 from moving under the action of inertia after the conveyor belt 4 stops. When the slope block 73 moves to the side of the second extrusion block 54, the two slope blocks 73 are pushed outward at the same time under the extrusion of the second extrusion block 54. At this time, the component body 8 between the clamping assembly 7 is separated from the clamping assembly 7, and the component body 8 enters the interior of the storage box 1 from the drop port 9.
