[0032] A fixing frame 43 is fixedly arranged on the top surface of the baffle 31. There are two fixing frames 43 arranged on the left and right. The two fixing frames 43 on the left and right are located on both sides of the handcart 41. A connecting groove is opened on the side surface of the fixing frame 43. The pulley 44 is located inside the connecting groove and is slidably connected to the inner wall of the connecting groove;
[0033] The buffering part includes a connecting rod 45. A positioning rod 46 is fixedly arranged on the back surface of the connecting rod 45. A fixing rod 47 is arranged behind the connecting rod 45. The fixing rod 47 is fixedly connected to the handcart 41. The rear end of the positioning rod 46 penetrates through the fixing rod 47 and is slidably connected to the fixing rod 47;
[0034] A positioning frame 48 is arranged in front of the connecting rod 45. The bottom surface of the positioning frame 48 is fixedly connected to the fixing frame 43. An air cushion is arranged between the connecting rod 45 and the positioning frame 48. A positioning groove is opened on the side surface of the positioning frame 48. There are two positioning grooves arranged up and down. Adjusting rods 49 are hingedly arranged on the side surface of the connecting rod 45. There are two adjusting rods 49 arranged up and down. The front ends of the adjusting rods 49 are located inside the adjacent positioning groove and are slidably connected to the inner wall of the adjacent positioning groove;
[0035] A moving rod 410 is arranged between the connecting rod 45 and the positioning frame 48. There are two moving rods 410 arranged up and down. Sleeves are sleeved on both the front and rear ends of the moving rod 410. The front and rear two sleeves are respectively fixedly connected to the connecting rod 45 and the positioning frame 48.
