DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the present invention, the supporting mechanism comprises a supporting plate 6 fixedly connected to the lower end of the test housing 1 , and a bottom plate 7 is fixedly connected to the lower end of the supporting plate 6 .

[0021] The sealing mechanism includes a sealing ring 13 arranged on the inner side of the fixed sleeve 8, the sealing ring 13 is fixedly connected to the side wall of the test housing 1, and a conical sealing nozzle 14 is fixedly connected to the end of the sealing ring 13 away from the test housing 1. The sealing ring 13 and the conical sealing nozzle 14 are integrally formed, and the sealing ring 13 and the conical sealing nozzle 14 are both made of corrosion-resistant rubber. A ring plate 10 is provided at the end of the fixed sleeve 8 away from the test housing 1, and a connecting sleeve 9 is fixedly connected to a side wall of the ring plate 10 close to the fixed sleeve 8. The connecting sleeve 9 is threadedly sleeved on the outer side wall of the fixed sleeve 8, and an extrusion sleeve 15 located on the inner side of the fixed sleeve 8 is fixedly connected to the side wall of the ring plate 10.

[0022] Furthermore, a locking bolt 11 is penetrated through the outer wall of the connecting sleeve 9, and the locking bolt 11 is threadedly connected to the connecting sleeve 9. The locking bolt 11 is abutted against the outer wall of the fixing sleeve 8.
