The fixed frame 1 is provided with two left and right parts, and the lower sides of the front and rear parts of the fixed frame 1 are connected with anti-slip pads to prevent movement.

The first motor 3 is connected to the right side of the upper rear part of the fixed frame 1, and the rotating shaft at the rear is connected to the output shaft of the first motor 3. A magnetic suction table 4 is connected between the rear of the fixed frame 1, and the coil 5 is connected to the magnetic suction table 4. The rear side of the right part of the magnetic suction table 4 is connected to the second motor 6. The magnetic suction table 4 A reciprocating screw rod 7 is rotatably connected to the rear portion, and the reciprocating screw rod 7 is connected to the output shaft of the second motor 6.
