Two chain lines 41 are arranged side by side in front and back on the chain line base 4, and the two chain lines 41 can stretch and contract in the left-right direction. Specifically, a servo motor 45 is arranged on the chain line base 4, the servo motor 45 is connected with the two chain lines 41, and provides power for the left-right stretching and contraction of the two chain lines 41, and the servo motor 45 can accurately return to the original point under the setting of an electric control program. The width between the two chain lines 41 is less than the width of the chain machine conveying line, so that the chain line 41 can be stretched into the chain machine conveying line.

[0024] Further, four baffle supports 11 are arranged on the vehicle body 1, and the four baffle supports 11 are distributed on the two sides of the two chain lines 41 correspondingly.
