[0020] like Figure 1-3 As shown, this embodiment provides a fixing fixture for chip packaging testing, including a handle 1, a beam 3, a first driving mechanism, and a second driving mechanism. The end of the handle 1 is connected to the beam 3 through a telescopic cylinder 2; the two ends of the beam 3 are vertically slidably connected to two telescopic rods 7, and the two telescopic rods 7 are installed on the beam 3 through the first driving mechanism. The first driving mechanism is used to synchronously drive the two telescopic rods 7 to slide horizontally toward or away from each other along the beam 3; the bottom of the telescopic rod 7 is fixedly connected to a fixture box 8, and two clamps 111 are extended from the inner side wall of the fixture box 8. The two clamps 111 are slidably connected to the fixture box 8, and the second driving mechanism is installed on the fixture box 8, and is used to synchronously drive the two clamps 111 to slide vertically toward or away from each other, and the clamps 111 are used to tighten the outer edge plate of the chip to fix the chip, and the sides of the clamps 111 that are close to each other are provided with stepped step platforms 1111.

[0021] The first driving mechanism includes a motor Ⅰ4 and a screw rod Ⅰ5. The screw rod Ⅰ5 is horizontally arranged and extends into the interior of the cross beam 3. The screw rod Ⅰ5 is a forward and reverse screw. Two sliders Ⅰ6 are symmetrically installed on the left and right sections of the rod body of the screw rod Ⅰ5. The two sliders Ⅰ6 are respectively fixedly connected to the tops of the two telescopic rods 7. The motor Ⅰ4 is fixedly installed outside the cross beam 3. The output shaft of the motor Ⅰ4 is fixedly connected to the end of the screw rod Ⅰ5. The motor Ⅰ4 drives the screw rod Ⅰ5 to rotate, thereby driving the slider Ⅰ6 to drive the telescopic rod 7 to move toward or away from each other along the screw rod Ⅰ5.

[0022] The left section and the right section of the screw rod Ⅰ5 are respectively processed with forward and reverse threads, and the screw rod Ⅰ5 is rotatably installed inside the crossbeam 3.

[0023] The second driving mechanism includes a screw rod Ⅱ10, a first bevel gear 91, a second bevel gear 101 and a motor Ⅱ9; the screw rod Ⅱ10 is installed in the fixture box 8 for vertical rotation; the screw rod Ⅱ10 is a forward and reverse screw rod, and sliders Ⅱ11 are respectively installed at the upper and lower ends of the screw rod Ⅱ10; the two sliders Ⅱ11 are fixedly connected to the clamping plate 111; the second bevel gear 101 is sleeved in the middle part of the screw rod Ⅱ10, the first bevel gear 91 is connected to the output shaft of the motor Ⅱ9, and the first bevel gear 91 is meshed with the second bevel gear 101.
