[0022] As Figure 1 and Figure 3 shown, the adaptation mechanism 4 includes a placing plate 41, fixing blocks 42, a motor 43, a bidirectional lead screw 44, moving plates 45, guide rods 46, ejector rods 47 and springs 48. A placing plate 41 is connected to the upper side of the mounting bracket 1. Four fixing blocks 42 are connected to the upper sides of the left and right parts of the mounting bracket 1, two in front and two in the back. A motor 43 is connected to the upper side of the right front part of the mounting bracket 1. A bidirectional lead screw 44 is connected to the output shaft of the motor 43. The front fixing blocks 42 are all rotatably connected with the bidirectional lead screw 44. A limit block is provided in the middle of the bidirectional lead screw 44 for easy limiting. The left and right parts of the bidirectional lead screw 44 are both threadedly connected with moving plates 45. A guide rod 46 is connected between the two rear fixing blocks 42. The moving plates 45 are all slidably connected with the guide rod 46. Twelve ejector rods 47 are slidably connected to the moving plates 45.
