[0014] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] The printed circuit board is mounted through surface mounting and through-hole mounting technology. After the tinning process, components of different sizes are installed to finally realize the production process of the entire product. The push-pull force experiment is to verify the binding force of different components. Therefore, the push-pull force fixture needs to meet the limit requirements of components of different sizes. Please refer to Figure 1-2The utility model is a fixing fixture suitable for push-pull force equipment, comprising: a base 1 and two groups of clamping components slidably arranged on the base for clamping printed circuit boards, the base is provided with a guide groove 2, the clamping component comprises a lower limit block 3 slidably arranged in the guide groove and an upper limit block 5 connected to the lower limit block by two groups of spring bolts 4, a clamping gap 6 for clamping printed circuit boards of different specifications is formed between the upper limit block and the lower limit block, the size of the clamping gap is adjusted according to the size of the printed circuit board by tightening or loosening the spring bolt, a sliding screw 7 is provided through the middle of the lower limit block, wherein The sliding screw and the lower limit block are threadedly connected, and a slider 8 is provided at the lower end of the sliding screw. The slider is slidably connected to the guide groove. The printed circuit board needs to be fixed in the horizontal direction, and the distance needs to be adjusted according to the different sizes of the product through flexible limit blocks. In the vertical direction, the flexible limit blocks need to have a certain height and thickness to meet the thrust test requirements of large-sized printed circuit boards. The universal clamp of the utility model can adjust the upper, lower, left and right spacings by flexibly adjusting the positions of the upper limit block and the lower limit block, and at the same time realize the experimental requirements of clamping and fixing the printed circuit board in the horizontal and vertical directions.

[0016] Specifically, the cross-section of the upper limit block is an "L"-shaped structure. The upper limit block includes a holding portion for holding the printed circuit board and two sets of wings connected to the lower limit block. The holding portion and the two sets of wings are an integrally formed structure. When the clamping gap needs to be adjusted, it can be adjusted by tightening or loosening the spring bolts on the two sets of wings to adapt to different models of printed circuit boards.

[0017] Compared with the previous fixture sliding limit block whose height is only 1cm, when conducting thrust experiments, when the printed circuit board needs to be fixed vertically, the experimenter needs to manually assist in fixing it. The thickness of the lower limit block of the utility model is 8CM-15CM, and printed circuit board products of different thicknesses can be fixed in the vertical direction.

[0018] In summary, the utility model discloses a fixing fixture suitable for push-pull force equipment, which can realize horizontal and vertical clamping and fixing of printed circuit board products at the same time, and can realize the fixture replacing manual fixation of experimenters, so as to meet the experimental needs of different products of different customers, save experimental costs and achieve better customer satisfaction, improve experimental efficiency, and ensure experimental safety.
