The adjustment plate 1 27 is hinged to the adjustment plate 2 29 through the rotating rod 28. A circular hole 210 is provided on the top surface of the adjustment plate 29, and a support rod 211 is fixedly connected to the inner side of the circular hole 210, and a clamping head 212 is fixedly connected to the top surface of the support rod 211. A slider 213 passes through the support rod 211. When the electrical cabinet is used for instruments of different sizes, if the instrument is small and has fewer electrical components inside, the toggle block 215 can be pulled upward, and the toggle block 215 will drive the connecting rod 214 to slide upward along the limiting groove 216, and the connecting rod 214 will drive the slider 213 to move upward together, and the slider 213 is slidably connected to the support rod 211, and the surface of the slider 213 is fixedly connected to the connecting rod 214, and the end of the connecting rod 214 away from the slider 213 is fixedly connected to the toggle block 215. A limiting groove 216 is provided on the inner side of the circular hole 210, and the connecting rod 214 passes through the limiting groove 216, and the connecting rod 214 is slidably connected to the limiting groove 216, and the support rod 211 passes through a reset block 217. When the slider 213 moves upward along the support rod 211, the reset block 217 is pushed upward together by the elasticity of the reset spring 218. When the reset block 217 moves upward for a certain distance, the top inclined surface of the reset block 217 will contact the inclined surface of the clamping block 25, so that the clamping block 25 pushes the square rod 23 through the square plate 24 to retract into the clamping hole 22, and the clamping spring 26 is compressed, and the reset block 217 is slidably connected to the support rod 211, and a reset spring 218 is fixedly connected between the bottom surface of the reset block 217 and the top surface of the slider 213. The bottom surface of the clamp head 212 is recessed upward, and the top surface of the reset block 217 can be embedded in the recessed part of the bottom surface of the clamp head 212. As the reset block 217 continues to move, the reset block 217 will gradually embed into the recessed part at the bottom end of the clamp head 212 and fit with the clamp head 212. At this time, the toggle block 215 is pulled back, and the reset block 217 and the clamp head 212 can be driven to move downward through the reset spring 218. The surface of the adjustment plate 29 is hinged with a cabinet door 219, and the inner side of the cabinet door 219 is fixedly connected with an explosion-proof glass 220. The inner side of the cabinet door 219 is provided with a groove 221, and the bottom surface of the cabinet door 219 is hinged with an explosion-proof plate 222, and the top surface of the adjustment plate 29 is clamped with a top plate 223.There are three groups of adjustment plates 27, and the bottom surfaces of the three groups of adjustment plates 27 are respectively connected to the top surface of the base 1.
