[0002] As the core component of microwave equipment, the performance of magnetron directly affects the operating efficiency and stability of the entire equipment. As an important component of magnetron, the accuracy and stability of the resistance value of magnetron filament is crucial to the normal operation of magnetron. However, in the production and maintenance process of magnetron filament, how to quickly and accurately detect its resistance value has always been a technical problem.

[0003] Traditionally, the testing of magnetron filaments mainly relies on manual operation, and tests are performed one by one through tools such as multimeters. This method is not only inefficient, but also easily affected by human factors, resulting in inaccurate test results. At the same time, due to the complex and delicate structure of the magnetron filament, the slightest carelessness during the test may cause damage, further increasing the difficulty and cost of the test.

[0004] With the continuous development of automation technology, people have begun to try to apply automation technology to the testing of magnetron filaments. However, the existing automated testing tools can only test the fixed position of the magnetron filament and cannot fully cover the different parts of the filament, resulting in limitations in the test results. In addition, the design of existing testing tools often lacks sufficient safety protection measures, which can easily cause damage to the magnetron filament during the test process.

[0005] Therefore, it is necessary to develop a new magnetron filament test fixture structure to solve the problems of low test efficiency, poor accuracy, incomplete testing and insufficient safety in the prior art. This new test fixture structure has the functions of automated testing, comprehensive coverage, flexible adjustment and safety protection to meet the actual needs of magnetron filament production and maintenance.
