[0020] 1. By setting up a flip mechanism, the transformer body can be completely located outside the protective cover, which is convenient for inspection and maintenance of the transformer body. The baffle is driven by the handle to rotate around the first fixed block, and the baffle is moved to the top of the transformer body. The baffle is limited by the baffle rod to prevent the baffle from falling. The first slider is driven to move in the limit frame by the baffle. The position of the first slider in the limit frame can be fixed by the cooperation between the mouth groove and the pull rod. The restoring force of the first spring after being compressed can drive the pull rod to move in the mouth groove. At the same time, the position of the baffle can be kept unchanged when the baffle is protruding, which is convenient for limiting the position of the protective cover.

[0021] 2. The transformer body can be protected by setting an anti-collision mechanism, and most of the impact force on the transformer body can be alleviated by setting a sleeve. The second spring is compressed to reduce a part of the impact force, and then the second spring causes the push rod to rise and reset. The push rod rises and contacts the damping block to absorb the rebound force, thereby further playing a buffering role. A part of the impact force can be unloaded by the elastic support plate. The elastic support plate drives the two second sliders to squeeze the third spring at the same time, and the third spring is compressed to absorb the excess impact force, thereby effectively protecting the transformer body; BRIEF DESCRIPTION OF THE DRAWINGS
