[0034] By adopting the above technical solution, two short screws 11 can be rotated according to the different length and width specifications of the semiconductor chip. The short screws 11 drive the small movable block 10 to move, which achieves the sliding adjustment effect of the connection part of L-shaped auxiliary frame A8 and L-shaped auxiliary frame B9. This allows L-shaped auxiliary frame A8 and L-shaped auxiliary frame B9 to contact the periphery of the semiconductor chip, thereby limiting the semiconductor chip and ensuring the stability of the semiconductor chip state. This better meets the assembly and limiting requirements of semiconductor chips of different specifications.

The L-shaped main frame B2 is equipped with a slide rail B202 at the top, and a longitudinal sliding hole B601 is opened in the top of the movable connector 6. The movable connector 6 is slidably connected to the L-shaped main frame B2 through the longitudinal sliding hole B601. The top of the connecting piece 6 is threaded to the bolt 12. The inner end of the bolt 12 connected to the top of the movable connecting piece 6 is in contact with the slide rail B202. A transverse sliding hole A602 is opened in the bottom of the movable connecting piece 6. The other end of the crossbar 5 is slidably connected in the transverse sliding hole A602.

[0036] By adopting the above technical solution, the crossbar 5, movable connector 6 and movable bracket 7 can be moved according to the different assembly positions of semiconductor chips on the circuit board, and the crossbar 5, movable connector 6 and movable bracket 7 can be fixed by bolts 12 to change the position of L-shaped auxiliary bracket A8 and L-shaped auxiliary bracket B9, thereby changing the assembly position of semiconductor chips, ensuring the accuracy of semiconductor chip assembly and positioning on the circuit board, and better meeting the needs of semiconductor chip assembly and positioning at different positions on the circuit board.
[0037] The specific usage and function of this embodiment are as follows: In this invention, firstly, according to the different length and width specifications of the circuit board, two long screws 4 are rotated respectively.

The adjustment effect allows L-shaped auxiliary brackets A8 and B9 to contact the periphery of the semiconductor chip, thus limiting the position of the semiconductor chip and ensuring its stability. This better meets the positioning requirements for assembling semiconductor chips of different specifications. Finally, depending on the assembly position of the semiconductor chip on the circuit board, the crossbar 5, movable connector 6, and movable bracket 7 are moved and fixed with bolts 12. This changes the position of L-shaped auxiliary brackets A8 and B9, thereby changing the semiconductor chip assembly position and ensuring the accuracy of semiconductor chip assembly positioning on the circuit board. This better meets the positioning requirements for semiconductor chips at different positions on the circuit board.
