         2 . The ball pushing mechanism according to  claim 1 , wherein the electric drive assembly comprises a motor and a gear train;
 both the motor and the gear train are disposed in the housing;   the motor and an input end gear of the gear train are in transmission connection, a tooth meshing portion is provided on an output end gear of the gear train, and a rack portion is provided on the pushing member;   in the standby state, the tooth meshing portion and the rack portion are meshed, and the motor is in a stationary state;   in the return state, the motor drives the output end gear to rotate, and the output end gear drives the pushing member to slide to retract from the communication port into the cavity; and   in the pushing state, the motor drives the output end gear to rotate until the tooth meshing portion disengages from the rack portion of the pushing member, and the ball pushing mechanism is switched to the pushing state.   
     
     
         3 . The ball pushing mechanism according to  claim 2 , wherein an arc-shaped plates is provided on the output end gear, and the tooth meshing portion and the arc-shaped plate are sequentially disposed along a peripheral side edge of the output end gear;
 the arc-shaped plate is provided with an outward convex arc surface on one side facing the pushing member; and   in the pushing state, the outward convex arc surface contacts the rack portion.   
     
     
         4 . The ball pushing mechanism according to  claim 3 , wherein the tooth meshing portion comprises a plurality of convex shafts, and the convex shafts are sequentially disposed at intervals along a circumference of an edge of the output end gear. 
     
     
         5 . The ball pushing mechanism according to  claim 4 , further comprising a trigger member movably provided in the cavity and partially extending out of the communication port;
 wherein in the standby state, under the action of an external force, the trigger member moves to trigger the motor to be energized, and the motor drives the output end gear to rotate until the tooth meshing portion disengages from the rack portion, so that the ball pushing mechanism is switched to the pushing state.   
     
     
         6 . The ball pushing mechanism according to  claim 5 , further comprising a switch electrically connected to the motor;
 wherein the trigger member is hinged to the housing by a rotating shaft, and a trigger column is provided on the trigger member; and   in the standby state, under the action of an external force, the trigger member rotates to contact and press the switch via the trigger column.   
     
     
         7 . The ball pushing mechanism according to  claim 6 , wherein a first circular arc groove and a second circular arc groove are provided on the output end gear, the second circular arc groove is communicated with the first circular arc groove, and the first circular arc groove and the second circular arc groove form a closed ring;
 a width of the second circular arc groove is greater than a width of the first circular arc groove;   the trigger member has a mating shaft, and a torsion spring is provided between the trigger member and the housing;   in the standby state, the mating shaft is located in the second circular arc groove, under the action of the torsion spring, a gap exists between the trigger column and the switch, and under the action of an external force, the pushing member rotates, so that the mating shaft moves toward a center of a drive gear, and the trigger column and the switch are in contact; and   in the return state, the mating shaft is located in the first circular arc groove, and the trigger column and the switch are kept in contact.   
     
     
         8 . The ball pushing mechanism according to  claim 7 , wherein the pushing member comprises an end body, a middle strip and side strips provided on both sides of the middle strip, the middle strip and the side strips are both connected to the end body, and the end body can extend out of the communication port or retract from the communication port into the cavity;
