[0026] The two sleeves 6 can be moved by the adjustment mechanism, which then drives the two fixed blocks 7 to move, and the two detection heads 20 to move at the same time, so that the device can be adapted to microelectronic semiconductors 2 of different sizes. At the same time, by fixing the detection head 20 inside the mounting hole, it is convenient to place the wire at one end of the detection head 20.

[0027] In order to move the two sleeves 6, as Figure 1-3 As shown, the adjustment mechanism includes two screw rods 8, a rotating rod 9, a first bevel gear 10 and two second bevel gears 11. The two screw rods 8 are respectively rotatably connected to the inside of the corresponding sliding grooves, and the two sleeves 6 are respectively threadedly sleeved on the rod walls of the corresponding screw rods 8. One end of the two screw rods 8 respectively penetrates one side of the corresponding sliding groove and extends to the inside of the cavity. The rotating rod 9 is rotatably connected to the lower surface of the inside of the cavity, the first bevel gear 10 is fixedly sleeved on the rod wall at the upper end of the rotating rod 9, and the two second bevel gears 11 are respectively fixedly connected to the rod wall at one end of the corresponding screw rod 8 and mesh with the first bevel gear 10. The lower end of the rotating rod 9 penetrates the lower surface of the cavity and is fixedly connected with a knob 17.

[0028] The knob 17 is rotated to rotate the rotating rod 9 , and then the two screw rods 8 are rotated through the transmission of the first bevel gear 10 and the two second bevel gears 11 , so that the two sleeves 6 can move left and right along the rod wall of the screw rod 8 .

[0029] In order to make the microelectronic semiconductor 2 movable, Figure 1-2 As shown, the fixing mechanism includes two pressing blocks 12, two connecting rods 13, two springs 14, two stoppers 15 and two fixing plates 16.
