A threaded rod passes through the connecting plate. An L-shaped support arm is arranged on the front surface of the connecting plate. A groove is penetrated through the free end surface of the L-shaped support arm. An electric cutter is connected inside the groove through an adjusting component.

[0006] Preferably, a top plate is arranged on the top surfaces of the two slide rods. The top end of the threaded rod penetrates through the top plate and extends upward to connect with the output end of a first motor.

[0007] Preferably, the adjusting component includes a rotating block. A rotating rod passes through the inside of the rotating block. One end of the rotating rod penetrates through the L-shaped support arm and extends outward to connect with the output end of a second motor. The other end of the rotating rod penetrates through the L-shaped support arm and extends outward to connect with a shaft rod. A connecting plate is sleeved on the outer wall of the shaft rod. A guiding rod passes through the end of the connecting plate opposite to the L-shaped support arm.

[0008] Preferably, a half-arc groove is opened on the other side wall of the L-shaped support arm. The free end of the guiding rod is slidably connected with the half-arc groove.
