[0034] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0035] See Figure 2 , this embodiment provides a sample transfer rod for transferring samples in a vacuum chamber, including a sample transfer tube 1 and a manipulation frame 2.

[0036] A magnetic rod 11 is movably inserted into the sample transfer tube 1, and a magnetic tube sleeve 12 is movably sleeved outside the sample transfer tube 1. The magnetic rod 11 has an internal magnet, and the magnetic tube sleeve 12 has an external magnet. The sample transfer tube 1, the magnetic rod 11, and the magnetic tube sleeve 12 are coaxially arranged. A connection flange 10 is provided on the chamber wall of the vacuum chamber. One end of the sample transfer tube 1 is connected to the vacuum chamber through the connection flange 10, and the other end of the sample transfer tube 1 is sealed. One end of the magnetic rod 11 facing the vacuum chamber has a sample rack 110 for placing samples in the vacuum chamber.

[0037] The manipulation frame 2 includes a fixed frame 21 and a telescopic frame 22. The fixed frame 21 is fixedly arranged on the magnetic tube sleeve 12. The telescopic frame 22 includes a handle 221 and a screw rod 222. The handle 221 is connected to the fixed frame 21 through the screw rod 222 and can be adjusted in position along the screw rod 222. Due to the interaction between the magnetic field of the internal magnet and the magnetic field of the external magnet, by manually driving the handle 221, the sample rack 110 can be driven to extend into the vacuum chamber to transfer samples. Among them, by adjusting the position of the handle 221 to adapt to the position of the operator, an operator can touch and drive the handle 221 during the process of observing sample transfer, realizing the accurate transfer of samples.

[0038] See Figure 3, the fixing bracket 21 includes a first mounting plate 211 and a second mounting plate 212. The first mounting plate 211 has a first central hole 2110, and the second mounting plate 212 has a second central hole 2120. The sample transfer tube 1 is movably inserted into the first central hole 2110 and the second central hole 2120, and the first mounting plate 211, the first central hole 2110, the second mounting plate 212, the second central hole 2120 and the sample transfer tube 1 are coaxially arranged. The magnetic tube sleeve 12 is clamped between the edge of the first central hole 2110 and the edge of the second central hole 2120 to realize the axial positioning of the magnetic tube sleeve 12.

[0039] A first mounting ring 2101 fixedly sleeved on one end of the magnetic tube sleeve 12 protrudes from the first mounting plate 211. Four mounting screws 213 are screwed on the first mounting ring 2101, and the four mounting screws 213 are evenly arranged along the circumferential direction of the first mounting ring 2101. Two symmetrically arranged set screws are screwed on the side of the first mounting ring 2101. The set screws are arranged along the radial direction of the first mounting ring 2101 and are abutted against the magnetic tube sleeve 12 to realize the circumferential positioning of the magnetic tube sleeve 12.

[0040] A second mounting ring 2102 fixedly sleeved on the other end of the magnetic tube sleeve 12 protrudes from the second mounting plate 212. The four mounting screws 213 pass through the second mounting plate 212 from the second mounting ring 2102, and a nut screwed on the mounting screw 213 is provided on the side of the second mounting plate 212 facing away from the first mounting plate 211. By tightening the nut on the mounting screw 213, the magnetic tube sleeve 12 is clamped. Among them, the first mounting ring 2101, the second mounting ring 2102 and the magnetic tube sleeve 12 are coaxially arranged.

[0041] Still referring to Figure 3 , the handle 221 in the telescopic bracket 22 is of an annular structure and sleeved on the sample transfer tube 1. The first mounting plate 211, the second mounting plate 212 and the handle 221 are coaxially arranged so that the center of gravity of the operating bracket 2 is closest to the axis of the sample transfer tube 1 to the greatest extent. When the handle 221 is not controlled by anyone, the handle 221 and the magnetic tube sleeve 12 will not rotate around the axis of the sample transfer tube 1 due to unstable center of gravity.

[0042] The screw rod 222 is movably inserted into the first mounting plate 211. Two adjusting nuts 2220 are screwed on the screw rod 222. One adjusting nut 2220 is arranged on one side of the first mounting plate 211, and the other adjusting nut 2220 is arranged on the other side of the first mounting plate 211. The end of the screw rod 222 away from the fixing bracket 21 is fixedly connected to the handle 221. Relative to the first mounting plate 211, the handle 221 is closer to the sample rack 110 at the end of the magnetic rod 11, which is convenient for the operator to operate.

[0043] The telescopic frame 22 further includes a guide rod 223 extending along the length direction of the screw rod 222. The guide rod 223 is movably inserted through the first mounting plate 211 to make the position adjustment of the handle 221 more stable. One end of the guide rod 223 is fixedly connected to the handle 221, and the other end of the guide rod 223 has an anti-disengagement block 2230 to prevent the screw rod 222 from disengaging from the first mounting plate 211. Wherein, the hole wall of the hole on the first mounting plate 211 for inserting the guide rod 223 is in close fit with the peripheral surface of the guide rod 223, and the hole wall of the hole on the first mounting plate 211 for inserting the screw rod 222 is spaced from the thread surface of the screw rod 222.

[0044] The extending directions of the screw rod 222 and the guide rod 223 are parallel to the axis of the sample transfer tube 1. There are multiple screw rods 222, and the multiple screw rods 222 are evenly arranged along the circumferential direction of the handle 221. There are multiple guide rods 223, and the multiple guide rods 223 are evenly arranged along the circumferential direction of the handle 221. Specifically, there are two screw rods 222 and two guide rods 223. The two screw rods 222 are symmetrically arranged with the axis of the handle 221 as the center, and the two guide rods 223 are symmetrically arranged with the axis of the handle 221 as the center, so that the center of gravity of the manipulation frame 2 is closest to the axis line of the sample transfer tube 1 to the greatest extent.

[0045] See Figure 4 , the first mounting plate 211 is separately provided and is divided into a first part 2111 of the first mounting plate and a second part 2112 of the first mounting plate that are buckled with each other. The connection parts of the first part 2111 of the first mounting plate and the second part 2112 of the first mounting plate respectively have screw holes, and the first part 2111 of the first mounting plate and the second part 2112 of the first mounting plate are detachably connected by screws screwed into the screw holes;

[0046] The second mounting plate 212 is separately provided and is divided into a first part 2121 of the second mounting plate and a second part 2122 of the second mounting plate that are buckled with each other. The connection parts of the first part 2121 of the second mounting plate and the second part 2122 of the second mounting plate respectively have screw holes, and the first part 2121 of the second mounting plate and the second part 2122 of the second mounting plate are detachably connected by screws screwed into the screw holes;

[0047] The handle 221 is separately provided and is divided into a first part 2211 of the handle and a second part 2212 of the handle that are buckled with each other. The connection parts of the first part 2211 of the handle and the second part 2212 of the handle respectively have screw holes, and the first part 2211 of the handle and the second part 2212 of the handle are detachably connected by screws screwed into the screw holes.

[0048] The first part 2111 of the first mounting disc, the first part 2121 of the second mounting disc, the first part 2211 of the handle, a screw rod 222 and a guide rod 223 connected to the first part 2111 of the first mounting disc are arranged on one side of the sample transfer tube 1; the second part 2112 of the first mounting disc, the second part 2122 of the second mounting disc, the second part 2212 of the handle, a screw rod 222 and a guide rod 223 connected to the second part 2112 of the first mounting disc are arranged on the other side of the sample transfer tube 1.

[0050] In this embodiment, the adjustment process of the control frame 2 and the use process of the sample transfer rod are as follows:

[0051] First, loosen the two adjusting nuts 2220 on each screw rod 222, and drive the handle 221 to move axially along the screw rod 222 relative to the magnetic tube sleeve 12 so that when the operator is in a position where the sample rack 110 can be observed, the handle 221 can be touched and driven.

[0052] Next, tighten the two adjusting nuts 2220 on each screw rod 222 and abut them against the first mounting disc 211.

[0053] Finally, an operator in a position where the sample rack 110 can be observed drives the handle 221 to drive the magnetic tube sleeve 12 to move, so that the sample rack 110 at the end of the magnetic rod 11 extends into the vacuum cavity to transfer the sample.
