[0002] A lightning arrester, also called a surge protector (hereinafter referred to as SPD), is an important circuit protection component. There are various types of SPDs on the market. Classified by width, they are mainly 18mm wide and multiples of this width, generally in the range of 18mm - 144mm. With different widths of SPDs, the spacing and number of their test points will change accordingly. The spacing of test points is generally in the range of 65mm - 75mm, and the number of test points is generally between two and five. The height variation of different types of SPDs is not significant, basically within 10mm. Therefore, when conducting a certain test on an SPD, after the test instrument is configured (the tester generally has 5 output points to the device), multiple sets of fixtures need to be replaced to meet the test requirements of various products. If made with a three-axis module, it will be relatively large in volume and high in cost. Secondly, it will be very difficult to switch between each test point.

[0006] As a further description of the above technical solution: When the pressure bar is pressed down, it drives the first probe assembly and the second probe assembly to move downward synchronously until the first probe assembly and the second probe assembly contact the test points of the lightning arrester. The first probe assembly and the second probe assembly are electrically connected to the test points of the lightning arrester, and the first socket assembly outputs test parameters to the test instrument.
