[0023] The bottom outer wall of the bottom plate 1 is welded with support blocks 7 distributed at equal distances, and a support sleeve 8 is welded at the position of the bottom outer wall of the bottom plate 2 3 corresponding to the support block 7. The outer wall of the support block 7 is slidably connected to the inner wall of the support sleeve 8. A protrusion 5 is welded at the center of the outer wall on one side of the bottom plate 1 and the bottom plate 2 3 close to each other. The support blocks 7 and the support sleeve 8 at the bottom of the bottom plate 1 and the bottom plate 2 3 are made of rubber material to increase the friction with the ground. After the bottom plate 1 and the bottom plate 2 3 are folded through the rotating shaft 2, the support block 7 is inserted into the inner wall of the support sleeve 8, which is convenient for folding and storage.

[0024] Sliding groove 1 9 and sliding groove 2 10 are connected to each other, and a fixing block 12 is welded to one end of the top outer wall of the sliding bar 11. An anti-slip protrusion 13 is provided at one end of the top outer wall of the fixing block 12. The anti-slip protrusion 13 is used to pull the sliding bar 11 and the mounting block 15 to move. After releasing, the spring 17 pulls the sliding bar 11 to move and makes the mounting block 15 contact with the outer wall of the circuit board, thereby fixing the circuit board, facilitating fixation, and facilitating auxiliary testing.

[0025] The outer walls of both sides of the fixing block 12 and the anti-slip protrusion 13 are slidably connected in the sliding groove 1 9, and the outer wall of one end of the anti-slip protrusion 13 contacts the bottom plate 1 and the bottom plate 2 3 at one end of the sliding groove 1 9. The sliding bar 11 is slidably connected to the bottom of the outer wall of the sliding groove 1 9 and the sliding groove 2 10. The fixing block 12 on the sliding bar 11 extends from the sliding groove 1 9 and protrudes from the sliding groove 2 10, which is convenient for fixing the circuit board.

The sliding bar 11 is pulled in the opposite direction through the anti-slip protrusion 13 on the sliding groove 1 9, so that the fixed block 12 at one end of the sliding bar 11 is retracted into the sliding groove 1 9, and the circuit board to be tested is placed in the placement groove 4. At this time, the spring 17 pulls the sliding bars 11 closer to each other and makes the fixed block 12 on the sliding bar 11 contact the side outer wall of the circuit board. Touch, fix the circuit board. At this time, test the circuit board through the test device. If the size of the circuit board is small, the sliding mounting block 15 is slidably connected in the sliding groove 10, and the mounting screw 16 at one end of the mounting block 15 is connected to the threaded hole 14 on the sliding bar 11 to fix the mounting block 15. Use the anti-slip protrusion 13 to pull the sliding bar 11 and the mounting block 15 to move. After loosening, the spring 17 pulls the sliding bar 11 to move and makes the mounting block 15 contact with the outer wall of the circuit board to fix the circuit board, which is convenient for fixation and auxiliary testing.
