[0024] The following will be combined with the drawings Figs. 1-3 The present application is further explained in detail.

[0025] The utility model discloses a bending test jig, which comprises a tripod 1, a moving frame 2, a mounting frame 3 and a servo motor 4. The inside of the tripod 1 is provided with slide rods 101 on both sides, the moving frame 2 is movably arranged in the inside of the tripod 1, sleeves 201 are mounted on both sides of the moving frame 2, and the sleeves 201 are movably arranged outside the slide rods 101. A support 202 is equidistantly penetrated and mounted in the inside of the moving frame 2 through bolts, a chuck 203 is mounted at the bottom of the support 202, the chuck 203 is an adjustable chuck, and the shape and size of the bending piece 302 can be adjusted according to the shape and size of the bending piece 302. The mounting frame 3 is arranged outside the slide rods 101 and below the moving frame 2, a clamping frame 301 is equidistantly mounted at the top of the mounting frame 3, the clamping frame 301 is clampedly mounted with the bending piece 302 in the inside, and the bending piece 302 is clamped by the chuck 203. The servo motor 4 is arranged at one side of the top of the tripod 1, an output end of the servo motor 4 is provided with a rotating shaft 401, an eccentric seat 402 is arranged at one side of the rotating shaft 401 through bolts, the mounting position of the eccentric seat 402 can be adjusted on the rotating shaft 401, a scale dial is arranged between the eccentric seat 402 and the rotating shaft 401, and the mounting position of the eccentric seat 402 is accurately adjusted.
