[0063] Embodiment 1

[0064] like Figure 4-5 As shown, in this embodiment, block three 340 is fixed to the outer wall of the conveyor belt 311 at a position close to one side of block two 330;

[0065] The extrusion unit 120 includes: an electric telescopic rod 121, one end of which is fixedly connected to the outer wall of the workbench 110; an arc block 122, fixed to the outer wall of the other end of the electric telescopic rod 121; and a square rod 123, one end of which is fixed to the outer wall of the arc block 122.

[0066] In this embodiment, when the frame 320 with the circuit board plugged in moves to the specified position, the personnel puts one end of the foot line on the block three 340, and the line body is placed on the conveyor belt 311. The electric telescopic rod 121 drives the arc block 122 to move downward and contact the outer wall of the block three 340.
