The upper clamping plate 2 and the lower clamping plate 3 are limited by the rotating shaft between the first connecting arm 201 and the second connecting arm 301, so that the position between the upper clamping plate 2 and the lower clamping plate 3 can be adjusted. A connecting head 302 is installed on one side of the lower clamping plate 3. The two ends of the connecting head 302 are respectively connected to the upper end of the adjusting frame 101 and the lower clamping plate 302. One side of the lower clamping plate 3 is rotatably connected via a rotating shaft.

[0029] To address the issue of poor positional stability of existing positioning fixtures during practical use, which affects work quality, please refer to... Figure 1 - Figure 4 This embodiment provides the following technical solution:
[0030] The rear end of the mounting backplate 1 is welded with a reinforcing rib 105. The surface of the mounting backplate 1 is provided with an integrally formed positioning hole.

During the adjustment of the tooling, the upper clamping plate 2 and the lower clamping plate 3 are limited by the spring rod 4 to improve the positional stability between the lower clamping plate 3 and the upper clamping plate 2, so as to adapt to the working intensity.
[0033] Specifically, after the mounting backplate 1 is fixed, the strength of the mounting backplate 1 is improved by the reinforcing rib 105.
