Two sets of slots are evenly provided on the front ends of the grooves on both sides of the fixing seat 2. The two ends of the four sets of second locking blocks 21 are slidably locked with the slots on one side of the groove of the fixing seat 2, and the two ends of the device body 1 are evenly connected to the other ends of the two sets of second locking blocks 21. The second locking blocks can slide in these slots and lock the two ends of the device body, which further enhances the connection stability between the device body and the fixing seat, thus enhancing the practicality.

[0027] This utility model discloses a power quality testing device. During operation, the operator first installs the fixed base at the designated location through the mounting holes on the positioning plate. Then, the operator moves one end of the device body, causing the mounting block and the fixed base groove to fit together until the rear end of the mounting block and the rear end of the fixed base groove are tightly abutted. Next, the operator pulls the protective plate, causing it to slide through the connecting plate and drive the second slider, compressing the first spring. This causes the two sets of first screws and the rotating handle to disengage from the U-shaped groove of the protective plate. The operator then rotates the two sets of first screws through the rotating handle, causing the two sets of first sliders to slide along the clamping plates until the two sets of first locking blocks engage with the mounting block's locking slots. Finally, other electrical equipment is connected to the device body for normal use. Before completing the above actions, the device should be moved to the desired location by the user.
