Sealing performance detection device with support and clamp functions used for automobile fuel tank

The invention discloses a sealing performance detection device with support and clamp functions used for an automobile fuel tank. The sealing performance detection device comprises a sealing performance detection box and a rotary shaft. The fuel tank is arranged in the middle position at the lower end of the sealing performance detection box. Additionally, two sides of the outer wall of the fuel tank are both equipped with clamp boards. The outer walls of the clamp boards are connected with threaded rods. The outer walls of the threaded rods are equipped with panels. Additionally, lower ends of the panels are provided with sliding grooves, interiors of which are equipped with movable sliding blocks. The device is equipped with a protection pad which is wear resistant and is not conducive.Water-proof rubber material can protect the bottom of the sealing performance detection device. Damage to the bottom of the detection device is avoided in the wet environment. Therefore, protection performance of the detectio
