[0034] Specifically, in an implementation scenario of the present invention, the shielding room of the plug-in replacement test bench comprises: a shielding room 100, a test bench 200, and a movable wall 300. A window 110 is provided on one wall of the shielding room 100. The window 110 is divided into an inner window 111 and an outer window 112. Shielding devices (not shown) are arranged around the inner window 111 and the outer window 112. The shielding devices include beryllium copper reeds, etc. A first half-moon-shaped slide groove 120 and a second half-moon-shaped slide groove 130 are arranged in the middle of the left and right sides of the inner window 11. The movable wall 300 is also arranged as an inner layer 310 and an outer layer 320. The inner layer 310 and the outer layer 320 are all surrounded by shielding devices, and the shielding devices include beryllium copper springs, etc. The middle of the left and right sides of the outer layer 320 are respectively provided with a first slide bar 140 and a second slide bar 150 that match the first slide groove 120 and the second slide groove 130. A third slide bar 160 and a fourth slide bar 170 are also provided between the first slide bar 140 and the second slide bar 150. The detection table 200 is detachably provided on the third slide bar 160 and the fourth slide bar 170. The first pull rod 331 and the second pull rod 341 are provided on the shielding room 100. The rods 341 are all supported by external brackets, which are not marked in the attached drawings for aesthetics. A first motor 330 and a second motor 340 are arranged on the movable wall 300.

When the motor rotates, the movable wall 300 can be pulled to slide. The first slide bar 140 and the second slide bar 150 can slide synchronously back and forth in the first slide groove 120 and the second slide groove 130 respectively, so that the movable wall 300 is separated or overlapped with the window 110. When the movable wall 300 is moved toward the shielding room When the detection table 200 is pulled out of the window 110 and separated from the window 110, it is necessary to replace the detection table 200. The detection table 200 is pulled out of the window 110. After the detection table 200 is removed, the debugged detection table to be used next is installed on the third slide bar 160 and the fourth slide bar 170. Then, under the action of the cylinder and the motor, the movable wall 300 is pushed back into the window 110 and overlaps with the window 110. At this time, the beryllium copper reed provided on the movable wall 300 contacts the beryllium copper reed provided on the window 110, so that the radio waves in the room are not leaked or the external interference factors do not enter the shielding room 100 to destroy the indoor electric field.
