Tension bracket for sampling for coating

The tension bracket comprises a base, a sample making plate and a fixing plate, two sets of mounting slots are formed in the top of the base, vertical rods are movably mounted on the inner sides of the mounting slots, the sample making plate is mounted on the inner side of the base, two sets of fixing bottom plates are mounted on the top of the base, and the fixing bottom plates are movably mounted on the inner sides of the vertical rods. The fixed bottom plate is positioned on the back surface of the mounting slot; fixing blocks are mounted on the two sides of the base, two sets of mounting holes are formed in one side of each fixing block, a hydraulic rod is mounted at the top of each fixing block, and a shaft sleeve is mounted at the top of each hydraulic rod. Through the installation of the shaft sleeve, the situation that machined materials are damaged due to long-time friction is effectively avoided. 本实用新型公开了一种涂层用打小样的张力架，包括底座，打样板和固定板，所述底座的顶部安装有两组安装插槽，所述安装插槽的内侧活动安装有立杆，所述底座的内侧安装有打样板，所述底座的顶部安装有两组固定底板，且固定底板
