[0022] As shown in the accompanying Figure 1 to the accompanying Figure 6The embodiment provides a mass spectrometer filament burning zone device, which comprises a shell 1, a molecular pump 2 fixedly connected to the left side of the shell 1, a box cover 3 arranged at the top of the shell 1, a fixed block 4 fixedly connected to the bottom of the inner cavity of the shell 1, a filament plug-in disc 5 arranged at the top of the fixed block 4, a plurality of first cavities 6 formed in the top of the filament plug-in disc 5, a copper block 7 fixedly connected to the bottom of the inner cavity of each first cavity 6, a fixing mechanism 8 arranged in the inner cavity of the copper block 7, locking structures 10 fixedly connected to the bottom of the filament plug-in disc 5, and placing grooves 11 formed in the two sides of the top of the fixed block 4.

[0023] Specifically, the fixing mechanism 8 comprises an annular block 81 arranged in the inner cavity of the first cavity 6, a supporting block 9 sleeved on the surface of the annular block 81 and fixedly connected with the filament plug-in disc 5, a plurality of guide blocks 82 slidably connected with the inner portion of the annular block 81, a clamping block 83 fixedly connected to one side of each guide block 82, a recess 84 formed in the other side of each guide block 82 and penetrating through the outer side of the annular block 81, and a spring ring 85 sleeved on the surface of each guide block 82 and located in the inner cavity of the recess 84.

[0024] In the embodiment, the fixing mechanism 8 is arranged to fix the mass spectrometer filament, and the position of the clamping block 83 can be moved, so that the mass spectrometer filaments of different specifications can be fixed.

[0025] Specifically, the locking structure 10 comprises square blocks 101 fixedly connected to the bottom of the filament plug-in disc 5, two second cavities 102 formed in the inner portion of each square block 101, movable blocks 103 slidably connected with the inner cavities of the second cavities 102, clamping blocks 104 fixedly connected to one side of each movable block 103, springs 105 fixedly connected to the other side of each movable block 103 and one end of each spring 105, and clamping grooves 106 formed in the two sides of the inner cavity of the placing groove 11 and matched with the clamping blocks 104.

[0026] In the embodiment, the locking structure 10 is arranged to fix the filament plug-in disc 5 and facilitate the user to disassemble the filament plug-in disc 5.

[0027] Specifically, a sliding groove 12 is formed in the top and the bottom of the inner cavity of the second cavity 102, and a sliding block 13 is slidably connected with the inner cavity of the sliding groove 12 and fixedly connected to one side of the movable block 103.

[0028] In the embodiment, the sliding groove 12 and the sliding block 13 are used in cooperation to limit the movable block 103 and improve the stability of the movable block 103 during movement.

[0029] Specifically, the bottom of the box cover 3 is fixedly connected with a sealing block 14 made of rubber.

[0030] In this embodiment, the sealing block 14 serves to seal the housing 1 and the cover 3, so that the inner cavity of the housing 1 can maintain a vacuum state when it is working.

[0031] Specifically, handles 15 are fixedly connected to both sides of the top of the filament insert 5, and the handles 15 are concave in shape.

[0032] In this embodiment, the handle 15 increases the contact area between the user's palm and the handle 15, thereby making it easier for the user to move the filament insert 5.

[0033] The working principle and usage process of this utility model are as follows: By placing the filament inside the annular block 81, the bottom of the filament will contact the clamping block 83, thereby driving the clamping block 83 to move towards the inner wall of the annular block 81. The clamping block 83 drives the guide block 82 to move, and the guide block 82 drives the spring coil 85 to stretch, thereby fixing filaments of different specifications.

[0034] By moving the handle 15 upward, the handle 15 moves the filament insert 5 upward, which in turn moves the square block 101 upward. As the square block 101 moves, it causes the locking block 104 to retract into the inner cavity of the second cavity 102. The locking block 104 moves the movable block 103, which in turn compresses the spring 105. As the locking block 104 continues to move, it will disengage from the inner cavity of the slot 106. When the locking block 104 is fully inserted into the inner cavity of the second cavity 102, the fixing of the fixed block 4 can be released, making it easier for the user to pick it up.

[0035] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
