A tensioning apparatus, comprising: a main body, comprising:a fixed end, for fixing the main body, anda free end;a locating piece between the fixed end and the free end of the main body; andan adjusting piece, comprising:a supporting part, supported between the free end and the locating piece, sa
1. A tensioning apparatus, comprising: a main body, comprising:a fixed end, for fixing the main body, anda free end;a locating piece between the fixed end and the free end of the main body; andan adjusting piece, comprising:a supporting part, supported between the free end and the locating piece, said supporting part comprising a bolt, the bolt comprising a first end and a second end, and the first end abutting the free end rotatably, and the locating piece comprising a through-hole, the bolt passing through the locating piece via the through-hole, and an operating part is a nut connected to the second end, and said operating part being, connected to the supporting part, and used for adjusting a length of the supporting part in the direction of extension of the main body and thereby tensioning the main body. 2. The tensioning apparatus as claimed in claim 1, wherein the through-hole comprises a first thread matching the bolt. 3. The tensioning apparatus as claimed in claim 1, wherein the locating piece also comprises a nut matching the bolt. 4. The tensioning apparatus as claimed in claim 2, wherein the operating part is a sleeve, an inner wall of the sleeve comprising a second thread, the second thread matching the bolt. 5. The tensioning apparatus as claimed in claim 4, wherein the supporting part comprises a connecting rod, the connecting rod comprising a third end and a fourth end; the second end and the third end are disposed facing each other in the sleeve, and the fourth end abuts the locating piece rotatably. 6. The tensioning apparatus as claimed in claim 5, wherein said bolt is a bolt, and wherein the connecting rod is a second bolt matching the second thread. 7. A superconducting magnet comprising: a low-temperature apparatus;a vacuum vessel in which said low-temperature apparatus is contained; anda tensioning apparatus comprising a main body comprising a fixed end, for fixing the main body, and a free end, a locating piece between the fixed end and the free end of the main body, and an adjusting piece comprising a supporting part, supported between the free end and the locating piece, and an operating part, connected to the supporting part, and used for adjusting a length of the supporting part in the direction of extension of the main body and thereby tensioning the main body; andsaid fixed end of said main body being connected to said low-temperature apparatus with a fixed but detachable connection, said locating piece being connected to said vacuum vessel with a fixed but detachable connection, and said vacuum vessel comprising at least one through-hole through which said main body passes. 8. A magnetic resonance apparatus comprising: a magnetic resonance data acquisition scanner comprising a superconducting magnet;said superconducting magnet comprising a low-temperature apparatus and a vacuum vessel in which said low-temperature apparatus is situated;a tensioning apparatus comprising a main body comprising a fixed end, for fixing the main body, and a free end, a locating piece between the fixed end and the free end of the main body, and an adjusting piece, comprising a supporting part, supported between the free end and the locating piece, and an operating part, connected to the supporting part, and used for adjusting a length of the supporting part in the direction of extension of the main body and thereby tensioning the main body; andsaid fixed end of said main body being connected to said low-temperature apparatus with a fixed but detachable connection, said locating piece being connected to said vacuum vessel with a fixed but detachable connection, and said vacuum vessel comprising at least one through-hole through which said main body passes.
