detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Example 1

Referring to FIG. 1 and FIG. 3 , an auxiliary positioning device for a test vessel includes a bracket 1 and a positioning splicing plate 2 .

The support 1 is composed of a rectangular frame 11 and four legs 12 uniformly arranged on the bottom surface of the rectangular frame 11 . Two symmetrical ]-shaped handles 13 are arranged on the bracket 1 , and the two ends of the ]-shaped handles 13 are symmetrically connected to the top surface of the rectangular frame 11 .

Below the rectangular frame 11 of the bracket 1, there are two symmetrical transverse struts 14, and the two ends of the transverse struts 14 are respectively connected to the upper parts of the two legs 12, and a symmetrical structure is formed between the two transverse struts 14 and the rectangular frame 11. 2 positioning slots 140; the top of the leg 12 has a jack connected to the positioning slot 140, the inner wall of the jack has an internal thread and is threaded with an adjusting screw 3, and the outer end of the adjusting screw 3 has a handle 30.
