[0034] The design of the connection structure enables flexible movement of the box cover 2 in the vertical and parallel directions, which not only facilitates the placement and removal of circuit boards, but also ensures effective shielding of the test slot 4 during the test process, thereby improving the convenience of equipment use and the accuracy of test results.
[0035] The box cover 2 and the box body 1 are connected by an innovative sliding connection method, which is first raised vertically and then moved back horizontally to open, so that the test slot 3 can be effectively exposed in a limited space, which is convenient for quickly putting in or taking out the circuit board to be tested, and does not take up a large space during the opening and closing process, so that the test device can be installed and arranged compactly, which not only reduces the intensity of manual operation, but also makes the entire test process smoother and more accurate.
[0036] Furthermore, two test slots 4 are provided, and the two test slots 4 are symmetrically arranged relative to the central axis of the test seat 3.

[0037] Specifically, the connection structure includes a first connecting rod 7 and a first cylinder 6 symmetrically arranged on both sides of the box body 1, the box cover 2 is connected to the first connecting rod 7, and the first connecting rod 7 is slidably connected to the first cylinder 6. The sliding connection between the first connecting rod 7 and the first cylinder 6 ensures that the box cover 2 moves stably and reliably, reduces the mechanical failure rate, and increases the service life of the equipment.
[0038] More specifically, the connection structure further includes a linkage plate 12, a second connecting rod 11 and a second cylinder 10, one side of the linkage plate 12 is connected to the first cylinder 6, the second cylinder 10 is located on the other side of the linkage plate 12 and connected to the box body 1, one end of the second connecting rod 11 is slidably connected to the second cylinder 10, and the other end is connected to the linkage plate 12.
