[0002] A circuit board is an indispensable electrical component in electronic devices, used to connect various controllers, sensors, and processors. After the circuit board is manufactured, in order to ensure its expected functions, a series of tests need to be carried out, and this quality control test process is generally carried out on a test platform with complete test functions. In the prior art, after the circuit board is fixed, the test head is held against the surface of the circuit board to realize the testing of the circuit board. However, when multiple groups of circuit boards are tested simultaneously, different circuit boards need to be fixed respectively. And when performing the next test, it is necessary to repeat the process of fixing different circuit boards in sequence and then testing them through the test head, resulting in low efficiency. Summary of the Invention

An arc-shaped rod is arranged on the surface of the sliding block, and a plugging rod is arranged at the end of the arc-shaped rod; and An extension plate, arranged on the surface of the rotating disk.

[0005] Preferably, a bracket is fixed on the surface of the base. A lifting groove is provided on the surface of the bracket. A lead screw is arranged inside the lifting groove and can rotate inside the lifting groove. A lifting rod is arranged in the lifting groove and can lift in the lifting groove. A test block is fixed at the end of the lifting rod, and the test block lifts along with the lifting rod.

[0006] Preferably, a test head is arranged at the bottom of the test block, and the test head lifts along with the test block. Multiple groups of first teeth are arranged inside the slot. The rotating disk is plugged into the slot and can rotate in the slot. Multiple groups of second teeth are fixed on the surface of the rotating disk, and the second teeth are engaged in the first teeth.

[0007] Preferably, a handle is fixed on the surface of the rotating disk. The rotating disk rotates with the handle.

A limiting plate is arranged at the bottom of the sliding block, and the limiting plate is plugged in the limiting groove. When the sliding block moves in the sliding groove, the limiting plate at the bottom of the sliding block moves in the limiting groove.

[0008] Preferably, two groups of arc-shaped rods are fixed on the surface of the sliding block. The end parts of the arc-shaped rods are plugged with plugging rods. The plugging rods can telescopically move inside the arc-shaped rods. Plugging grooves are formed on the surfaces of the arc-shaped rods, and stress rods are plugged in the plugging grooves. The stress rods are connected to the surfaces of the plugging rods, and the stress rods move with the plugging rods. One end of the plugging rod located inside the plugging groove is connected with a second spring, and the second spring is located inside the plugging groove.

Rotate the sliding block through the handle, and the second tooth teeth are stuck in the first tooth teeth to stabilize the position of the sliding block. Step 2: Testing. Push the sliding block so that it moves in the sliding groove. A limiting plate is inserted at the bottom of the sliding block, and the limiting plate is inserted into the limiting groove. When the sliding block moves to the middle position of the rotating disk, the spring at the end of the plugging rod pushes the plugging rod, causing the plugging rod to extend from the plugging groove. The plugging rod is inserted into the plugging hole to stabilize the position of the sliding block. When the test block descends, the circuit board can be directly tested. When testing another group of circuit boards, pull up the stress rod to withdraw the plugging rod from the plugging hole, rotate the sliding block to rotate another group of sliding blocks, and push another group of sliding blocks so that another group of sliding blocks can directly move to the position directly below the test block to quickly test another group of circuit boards.
