Step 2: by the rotating speed of touch display screen (41) input main shaft (6) and the rotating speed of single axle (11), input finishes the back by the start key on the sub-screen, this enabling signal subsequently, the tach signal of input main shaft (6) and the tach signal of single axle (11) are transferred to the COM1 (35) of programmable logic controller (PLC) PLC by the communications cable (38) by the output signal port of touch display screen (41), after programmable logic controller (PLC) PLC (33) converts the tach signal of the tach signal of the main shaft (6) of input and single axle (11) to converter plant accessible tach signal respectively by its inner single spindle motor rate control module and spindle motor rate control module subsequently, then according to second control signal output port (32) and the three control signal output port (31) of enabling signal by programmable logic controller (PLC) PLC (33), the tach signal of the input main shaft (6) after handling and the tach signal of single axle (11) are sent to the controlled receiving port (63) of spindle motor converter plant (46) and the controlled receiving port (62) of crankshaft motor converter plant (43) with the control instruction form respectively by communication cable, and crankshaft motor converter plant (43) and spindle motor converter plant (46) rotate according to the corresponding motor of rotating speed control instruction startup that receives separately respectively immediately;

Step 3: when the user by the first strip wooden man arm (28), when hit at the attack position of the second strip wooden man arm (29) or the 3rd strip wooden man arm (30), by the output signal port of the pressure sensor (45) installed on this attack position will gather by signal to attack by wireless signal transmitter (44) emission wireless pulses, by wireless signal receiver (40) signal is exported to the input signal port (36) of programmable logic controller (PLC) PLC (33) again, the counting module of being attacked by programmable logic controller (PLC) PLC (33) adds one function treatment and obtains by number of times of attack, with being received by the controlled receiving port (39) that communication cable sends to touch display screen (41) after handling by the first control signal output port (34) of number of times of attack signal by programmable logic controller (PLC) PLC (33), demonstration at display screen is immediately gone out by the numerical value of number of times of attack by the position display of number of times of attack, by the second control signal output port (32) of programmable logic controller (PLC) PLC (33) the counter-rotating control instruction of crankshaft motor (61) is sent to the controlled receiving port (62) of crankshaft motor converter plant (43) simultaneously by communication cable, crankshaft motor converter plant (62) reverses according to this instruction driving crankshaft motor (61) immediately, drive single axle (11) guiding respective link (12) by shaft coupling (13) and oppositely move, cause the wooden man arm of the correspondence of strip wooden man arm group to shrink; When the user hit on the outer sleeve (19) attacked the position time, attacked the pressure sensor of installing on the position (45) by this signal to attack of gathering is launched wireless pulses by wireless signal transmitter (44), by wireless signal receiver (40) signal is exported to the input signal port (36) of programmable logic controller (PLC) PLC (33) again, attack counting module by programmable logic controller (PLC) PLC (33) adds one function treatment and obtains number of times of attack, the first control signal output port (34) of number of times of attack signal after handling by programmable logic controller (PLC) PLC (33) sent to controlled receiving port (39) reception of touch display screen (41) by communication cable, go out the numerical value of number of times of attack immediately in the position display of the demonstration number of times of attack of display screen.
