[0080] like Figure 2 and Fig. 9 As shown:

[0081] The fixed clamping mechanism 5 includes a limit block 51, a guide column 52, a first spring 53, a pressing bracket 54, a limit slide rail 55 and an elastic reset mechanism 56; the limit block 51 is provided with a plurality of and evenly distributed on the limit installation shell 3, and the limit block 51 is slidably connected to the limit installation shell 3; the guide column 52 is provided with a plurality of and evenly distributed on the limit block 51, one end of the guide column 52 is fixed to the limit block 51, and the end of the guide column 52 away from the limit block 51 is slidably connected to the limit installation shell 3; the first spring 53 is provided with Several and evenly distributed on the guide column 52, one end of the first spring 53 is in conflict with the limit block 51, and the end of the first spring 53 away from the limit block 51 is in conflict with the limit mounting shell 3; there are several limit slide rails 55 symmetrically arranged on the limit mounting shell 3, and the limit slide rails 55 are fixedly connected to the limit mounting shell 3; the pressing bracket 54 is slidably connected to the limit slide rail 55; the elastic reset mechanism 56 is fixedly installed on the limit mounting shell 3, and the end of the elastic reset mechanism 56 away from the limit mounting shell 3 is fixedly connected to the pressing bracket 54.

[0082] The positioning guide column 7 passes through the hole of the PCBA board. The positioning guide column 7 is used to guide the PCBA board to drop horizontally to the specified position. The staff presses the pressing bracket 54, and the pressing bracket 54 moves along the limiting slide rail 55. The contact end of the pressing bracket 54 contacts the limiting block 51, so that the limiting block 51 and the guide column 52 shrink synchronously, and the first spring 53 is squeezed. When the limiting block 51 shrinks, the test pin 6 contacts the specified position of the PCBA board. The staff cancels the pressing of the pressing bracket 54, and the elastic reset mechanism 56 pushes the pressing bracket 54 back to its original position, so that the limiting block 51 clamps and fixes the PCBA board.

[0088] When the staff pushes the pressing column 541, the pressing column 541 drives the pushing rod 542 to move synchronously. When the pushing rod 542 moves, it pushes the pressing rod 543 to slide along the limiting slide rail 55. The inclined guide angle 5431 of the pressing rod 543 conflicts with the limiting pressing inclined groove 512 inside the limiting block 51, causing the limiting block 51 to shrink and move.

[0089] like Fig. 9 , Fig.13 and Fig.14 As shown:

[0090] The elastic reset mechanism 56 includes a fixed mounting sleeve 561, a reset telescopic rod 562 and a second spring 563; the fixed mounting sleeve 561 is fixedly mounted on the positioning mounting rail 2; the reset telescopic rod 562 is slidably mounted on the fixed mounting sleeve 561; the second spring 563 is fixedly arranged inside the fixed mounting sleeve 561, one end of the second spring 563 is in contact with the fixed mounting sleeve 561, and the end of the second spring 563 away from the fixed mounting sleeve 561 is fixedly connected to the pressing bracket 54.

[0097] The first rail 21 and the second rail 24 are used to cooperate with the limit slider 32 of the limit mounting shell 3. When the limit mounting shell 3 is pushed to move horizontally, the limit slider 32 is driven to slide. When the positioning hole 321 of the limit slider 32 moves to the telescopic positioning column 22, the third spring 23 pushes the telescopic positioning column 22 to extend upward and insert into the positioning hole 321 of the limit slider 32, so as to position and fix the limit mounting shell 3 at the specified position. When the staff needs to release the lock, the pressing block 221 of the telescopic positioning column 22 is pressed downward to disengage the telescopic positioning column 22 from the positioning hole 321 of the limit slider 32 and release the fixation.
