[0001] The utility model relates to the technical field of fixture auxiliary devices, in particular to a fixture structure capable of clamping test materials of different thicknesses. Background Art
[0002] At present, the test materials of semiconductors in the TO semiconductor industry are uneven. The use of conventional test fixtures will lead to a series of problems such as failure to press, damage to materials, poor compatibility, etc., which makes push-pull force tests in the semiconductor industry difficult and the test results are inaccurate. The fixture structure that can freely adjust the pressure intensity can solve this series of problems.
[0003] At the same time, the products on the market at this stage have poor compatibility. Each material requires a corresponding fixture to be designed specifically. Within the range of adjustable height, materials of different heights can be used to keep the pressure at a moderate level. Since the products on the market are almost all designed specifically, each time a material is changed during use, the fixture needs to be replaced simultaneously, and replacing different fixtures will inevitably increase production costs.

[0009] As a preferred embodiment, the driving mechanism includes a rotating shaft, a rotating handle and a rebound assembly. The rotating shaft is arranged between the upper and lower movable side plates and the fixed seat, and the rotating shaft is rotatably connected to the fixed seat. The rotating handle is rotatably arranged on one side of the fixed seat, and one end of the rotating handle extends to the inner side of the fixed seat and is connected to the rotating shaft.
