     DETAILED DESCRIPTION OF THE INVENTION 
     The technical contents, structural features, objectives and effects of the invention are detailed below with reference to an embodiment and the accompanying drawings. 
     The key conception of the invention is that kinetic energy generated when an upper body assembly swings is used to drive arm assemblies to stretch or retreat to simulate attack motions from opponents in actual combat, thus fulfilling a good training effect and being highly targeted. 
     Referring to  FIGS. 1-4 , a novel active wooden dummy comprises a lower limb assembly  1 , an upper body assembly  2  and two arm assemblies  3 . The lower limb assembly  1  is provided with a driving device  11  and a spindle  12 . The spindle  12  is vertically arranged. The upper body assembly  2  is rotatably arranged on the spindle  12 . The driving device  11  drives the upper body assembly  2  to repeatedly swing leftwards or rightwards. Each arm assembly  3  comprises a front arm rod  31 , a rear arm rod  32 , a turning rod  33  and a connection rod  34 . Two connection ends extending towards two sides to be rotatably connected with ends of the connection rods  34  are formed on the spindle  12 . The middle of each turning rod  33  is rotatably fixed to the upper body assembly  2 . Each turning rod  33  has an end rotatably connected with the corresponding connection rod  34  and an end rotatably connected with an end of the corresponding front arm rod. Each rear arm rod  32  has an end rotatably connected with an outer wall of the upper body assembly  2  and an end rotatably connected with a back side of the corresponding front arm rod  31 . 
     The working process of the novel active wooden dummy is as follows: the driving device  11  drives the upper body assembly  2  to repeatedly swing leftwards or rightwards; as the spindle  12  is stationary, the arm assemblies  3  swing along with the upper body assembly  2 ; the distance between the turning rods  33  and the connection ends varies all the time when the arm assemblies  3  swing, so that every time the arm assemblies  3  swing, the connection rods  34  pull the turning rods  33  downwards, the other ends of the turning rods  33  are lifted to push the front arm rods to stretch forwards to simulate punching motions; and then, the upper body assembly  2  continues to swing, and the front arm rods retreat under the effect of self weights and rotation of the turning rods  33  when the pulling force of the connection rods  34  disappears. 
     Furthermore, the upper body assembly  2  is provided with a head and a neck. A tension spring is arranged in a joint of the head and the neck. When impacted, the head swings in the impact direction. The head can swing in any directions. 
     Furthermore, four sliding wheels are arranged at the bottom of the lower limb assembly  1  so that the lower limb assembly  1  can horizontally slide on the ground. A left side and a right side of the bottom of the lower limb assembly  1  are connected with the ground through tension springs. When impacted, the upper body assembly  2  and the lower limb assembly  1  retreat; and when an impact force disappears, the upper body assembly  2  and the lower limb assembly  1  return to original positions. 
     Therefore, the invention has the following beneficial effects: the structure is simple; kinetic energy generated when the upper body assembly  2  swings is used to drive the arm assemblies  3  to stretch or retreat, the whole wooden dummy can be driven by one driving device  11  to move, and the arm assemblies  3  stretch or retreat when the upper body assembly swings, so as to simulate attack motions from opponents in actual combat; and when used for single training, the novel active wooden dummy can simulate defense motions, dodging motions, counterattack motions and the like, thereby fulfilling a good training effect and being highly targeted. 
     Furthermore, each turning rod  33  comprises an inner rod  331 , a rotary shaft  332  and an outer rod  333  which are perpendicularly connected in sequence. The inner rods  331  and the outer rods  333  are separately arranged on an inner side and an outer side of the upper body assembly  2  and extend in opposite directions. The rotary shafts  332  are rotatably mounted in through holes formed in a left side and a right side of the upper body assembly  2 . 
     Therefore, the turning rods  33  of this special structure can be firmly fixed to the upper body assembly  2  and can transmit rotation power out of the upper body assembly  2  from the interior of the upper body assembly  2 . 
     Furthermore, the novel active wooden dummy further comprises pressure sensors  4  and displays  5 , wherein the pressure sensors  4  are located on a surface of the upper body assembly  2  and are electrically connected with the displays  5 . 
     Therefore, when trainees attack the upper body assembly  2 , the pressure sensors  4  sense the attack force, and force values are displayed on the displays  5  for reference by the trainees. 
     Furthermore, the displays  5  are arranged on the eyes of the head of the upper body assembly  2 . 
     Because the displays  5  are arranged on the eyes of the head of the upper body assembly  2 , sights of the opponents can be accurately observed in actual combat, and the training condition is more similar to actual combat. 
     Furthermore, the driving device  11  comprises a motor  111 , a rotary table  112  and a link rod  113 , wherein the rotary table  112  is rotatably and horizontally arranged on the lower limb assembly  1 , the motor  111  is arranged on the lower limb assembly  1  and drives the rotary table  112  to rotate, and one end of the link rod  113  is rotatably arranged on an edge of an upper surface of the rotary table  112 . 
     Therefore, every time the rotary table  112  rotates, the upper body assembly  2  is pulled or pushed to repeatedly swing leftwards or rightwards. 
     Please refer to  FIGS. 1-4  for the first embodiment of the invention:
