It is one of the most important test methods in the immunity test of electronic information products. Among them, in order to test the field strength of the electromagnetic field, a field strength probe is required to perform fixed-point detection at different locations, generally at a certain distance, such as 50 cm, for a measurement. In the prior art, manually finding points in space is time-consuming and laborious, and there are often errors in the measurement position, which has a large room for improvement.

[0019] 1. The electric field probe is installed on the mounting arm, and the height is changed by clamping the mounting arm at different positions of the lifting column. The lifting column is inserted into different mounting holes to change the horizontal position, so as to accurately change the position of the electric field probe in the horizontal direction or vertical direction to measure the field strength.
[0020] 2. When the lifting column is inserted into the mounting hole, the first screw can push the lifting column to press against the wall of the mounting hole, thereby locking the lifting column and preventing the lifting column from falling out of the mounting seat or rotating.
[0021] 3. The adjustment seat is movably connected to the guide hole of the base through the guide column. Therefore, the horizontal position of the electric field probe can be further changed by changing the position of the adjustment seat relative to the base and moving the lifting seat from the mounting seat of the base to the lifting seat of the adjustment seat.
[0022] 4. When the guide column moves along the guide hole, the second screw can push the guide column to press against the wall of the guide hole, thereby locking the guide column and preventing the guide column from moving arbitrarily in the guide hole and changing the position of the adjustment seat relative to the base.
[0023] 5. The number of lifting columns is at least two and the connection protrusion of one lifting column can be inserted into the connection recess of another lifting column. The adjustable clamping height of the mounting arm can be increased by stacking the lifting seats.
[0024] 6.
