[0019] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is combined with the drawings and examples, and the utility model is further detailed.The specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] Embodiment:

[0021] Reference Figures 1-4 The automobile support multi-size positioning clamp includes a bottom plate 1, a side plate 2 is fixedly connected on the bottom plate 1, clamping cylinders 3 are fixedly connected on the both sides of the side plate 2, a base 8 is fixedly connected on the side plate 2 beside the clamping cylinders 3, first positioning seats 4 are slidably connected on the base 8, sliding tables 301 are fixedly connected on the piston rods of each clamping cylinder 3, chucks 5 and second positioning seats 6 are slidably connected on the two sliding tables 301 respectively, positioning holes are formed in the chucks 5 and the second positioning seats 6, a connecting crossbeam 7 is slidably connected on the bottom plate 1, and the both sides of the connecting crossbeam 7 are fixedly connected with the chuck 5 and the second positioning seat 6.

[0022] The threaded rod 9 of the base 8 is screwed to adjust the height of the first positioning seat 4 on the side plate 2, and the first positioning seat 4 is lifted or lowered by rotating the threaded rod 9. The first positioning seat 4 is provided with an inclined groove, and the included angle formed by the inclined groove and the side plate 2 facilitates the placement of the automobile support.

[0023] The chuck 5 comprises an outer sleeve 501, a clamping rod 502 and a spring 503. The outer sleeve 501 is fixedly connected with the connecting beam 7, the clamping rod 502 is slidably connected with the outer sleeve 501, and the clamping rod 502 can slide relative to the outer sleeve 501 to compensate during assembly after clamping the automobile support. The spring 503 is located between the clamping rod 502 and the outer sleeve 501.

[0024] The positioning hole of the second positioning seat 6 is fixedly connected with a magnet, which can prevent the automobile support from being separated from the second positioning seat 6 during clamping. The sliding of the connecting beam 7 can drive the chuck 5 and the second positioning seat 6 to synchronously adjust the position, thereby improving the convenience of adjustment operation.

[0025] The working principle of the utility model is as follows: when adjusting before use, the height of the first positioning seat 4 on the side plate 2 can be adjusted by rotating the threaded rod 9, and the positions of the chuck 5 and the second positioning seat 6 can be synchronously adjusted by sliding the connecting beam 7. The adjustable first positioning seat 4 and the second positioning seat 6 are suitable for positioning automobile supports of different sizes (the distance between the two pipes of the automobile support is different).
