The second driving member 310 is installed on the base 100 and the driving shaft of the second driving member 310 is connected to the second sliding seat 320, so as to drive the second sliding seat 320 to move in the front - rear direction, thereby driving multiple second pressing rod assemblies 330 to move in the front - rear direction simultaneously. When the second pressing rod assembly 330 moves backward, the end of the second pressing rod assembly 330 abuts against the cross bar 400 and presses the hanging ear 500 against the cross bar 400, thereby realizing the positioning of the cross bar 400 and making the cross bar 400 and the hanging ear 500 relatively stationary.

[0036] During operation, multiple cross bars 400 are respectively received in the positioning grooves 110, multiple hanging ears 500 are placed on the base 100 and cooperate with the ends of the cross bars 400 respectively. The first driving member 210 drives multiple first pressing rod assemblies 230 to move downward simultaneously and presses the hanging ears 500 against the base 100. The second driving member 310 drives the second pressing rod assemblies 330 to move towards the cross bar 400 simultaneously and presses the hanging ears 500 against the base 100, thereby realizing the simultaneous positioning of multiple groups of cross bars 400 and hanging ears 500 on the base 100, and the cross bars 400 and the hanging ears 500 are relatively stationary. The positioning efficiency is high, there is no need to operate the first driving member 210 and the second driving member 310 multiple times, which is convenient for operation and is beneficial to ensuring the welding consistency of the product.

The first spring 232 is sleeved on the screw rod 231, and the two ends of the first spring 232 respectively abut against the head 234 and the first sliding seat 220. Therefore, the screw rod 231 can move up and down relative to the first sliding seat 220. When the head 234 of the screw rod 231 presses against the hanging ear 500, the first sliding seat 220 exerts a downward force on the first spring 232, and the first spring 232 then exerts a downward force on the head 234. The screw rod 231 has a soft contact with the hanging ear 500. Under the action of the first spring 232, the head 234 of the screw rod 231 can always keep pressing against the hanging ear 500, improving the stability.
