Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1 and 3, the waveform generator interface protection assembly provided by the present invention includes an apparatus main body 1 and a fixing box 2. The bottom of the fixed box 2 is symmetrically provided with a slot plate 3, and the top end of the fixed box 2 is fixedly connected with a limiting mechanism 4. The fixed box 2 is movably connected with a baffle mechanism 5, and the baffle mechanism 5 comprises a shielding plate 51, a rotating shaft 52, a cover plate 53 and a torsion spring 54. A plurality of through holes are equidistantly formed in the shielding plate 51, a cover plate 53 is connected to the inside of each through hole through a rotating shaft 52, and torsion springs 54 located on the rotating shafts 52 are sleeved on two sides of each cover plate 53.
