An electric slide rail 2 is fixedly installed at the top of the bracket 1. A tray 3 is slidably installed on the electric slide rail 2. Four fastening bolts 301 for fixing the coating sample 4 are threadedly connected at the four corners of the tray 3. The four fastening bolts 301 are symmetrically arranged. A coating sample 4 is placed on the tray 3. The shape and size of the coating sample 4 are correspondingly arranged with the positions of the four fastening bolts 301. Fans 9 for drying the adhesive between the coating sample 4 and the pulling head 401 are arranged on both the left and right sides of the tray 3. The two fans 9 are symmetrically arranged left and right. Two cylinders 8 are symmetrically installed at the top of the fixing frame 101. The telescopic ends of the cylinders 8 face downward. A connecting plate 801 is fixedly connected between the telescopic ends of the cylinders 8. A pulling connection head 502 is fixedly arranged on the connecting plate 801. A pulling detector 5 is installed at the top of the fixing frame 101. The pulling detector 5 is connected to the pulling connection head 502 on the connecting plate 801 through a connecting pipe 501.
