[0022] Bracket frame 1;

[0023] The adjustment structure is provided on the support frame 1;

[0024] The adjustment structure includes four support rods 2, two linear guide rods 3, a movable splint 4 and an upper splint 5. One end of the four support rods 2 is fixed on the bracket frame 1, and the other end of the four support rods 2 is fixed on the upper splint 5. The inner wall of the movable splint 4 is slidably sleeved on the four support rods 2. One end of the outer wall of the two linear guide rods 3 is rotatably embedded in the bracket frame 1, and the other end of the outer wall of the two linear guide rods 3 is rotatably embedded in the upper splint 5. The outer walls of the two linear guide rods 3 are threadedly embedded in the movable splint 4.

[0025] In this embodiment: the upper splint 5 can be fixed above the bracket frame 1 through four support rods 2, and the movable splint 4 can slide up and down. The outer walls of the two linear guide rods 3 are threaded. During the rotation of the two linear guide rods 3, they can be threaded on the movable splint 4, driving the movable splint 4 to slide up and down. The two ends of the linear guide rods 3 are restricted by the bracket frame 1 and the upper splint 5, providing a stable rotation space.

[0026] Specifically, the adjustment structure further includes a linear stepping motor 6 . The top of the outer wall of the linear stepping motor 6 is mounted on the bracket frame 1 . The output end of the linear stepping motor 6 is fixedly sleeved with a main gear 7 .

[0027] In this embodiment, the output end of the linear stepping motor 6 can rotate forward and reverse when powered, and the number of revolutions can be controlled, thereby controlling the main gear 7 at the output end to rotate.

[0028] Specifically, the outer bottoms of the two linear guide rods 3 are fixedly sleeved with auxiliary gears 8 , and the auxiliary gears 8 and the main gear 7 are meshed with each other.

[0029] In this embodiment, the secondary gear 8 and the main gear 7 are meshed with each other, so that the main gear 7 can drive the secondary gear 8 to rotate, thereby providing a rotational force for the linear guide rod 3.

[0030] Specifically, a protection frame 9 is fixedly provided on the top of the outer wall of the bracket frame 1 , and the outer walls of the auxiliary gear 8 and the main gear 7 are rotatably disposed between the protection frame 9 and the bracket frame 1 .

[0031] In this embodiment, the protection frame 9 can protect the secondary gear 8 and the main gear 7, so that the secondary gear 8 and the main gear 7 can rotate more stably.

[0032] Specifically, a tube clamping plate 10 is fixedly embedded on the top of the outer wall of the movable clamping plate 4 , and a silicone tube 11 is placed on the tube clamping plate 10 .

[0033] In this embodiment, the tube clamping plate 10 can prevent the silicone tube 11 from sliding out after being placed, and a groove is formed between the tube clamping plate 10 and the movable clamping plate 4 to limit the sliding of the silicone tube 11.

[0034] Specifically, a plurality of mounting holes are formed on the outer wall of the bracket frame 1 .

[0035] In this embodiment, the bracket frame 1 is conveniently installed and fixed through the multiple installation holes of the bracket frame 1.

[0036] When in use, the bracket frame 1 is fixed using multiple mounting holes, and the silicone tube 11 is placed between the tube clamping plate 10 and the movable splint 4 to form a groove to limit the sliding of the silicone tube 11. After the vacuum value is set, the linear stepper motor 6 drives the linear guide rod 3 by forward or reverse rotation according to the real-time vacuum value, pushing the movable splint 4 up or down, completing the automatic control of the vacuum value. The four support rods 2 can fix the upper splint 5 above the bracket frame 1 and make the movable splint 4 slide up and down. The outer walls of the two linear guide rods 3 are threaded, and the two linear guide rods 3 can be threaded on the movable splint 4 during rotation, driving the movable splint 4 to slide up and down. The two ends of the linear guide rod 3 are restricted by the bracket frame 1 and the upper clamping plate 5, providing a stable rotation space. The output end of the linear stepper motor 6 can rotate forward and reverse when powered on, and the number of rotations can also be controlled, thereby controlling the rotation of the main gear 7 at the output end. The sub-gear 8 and the main gear 7 are engaged with each other, so that the main gear 7 can drive the sub-gear 8 to rotate, thereby providing the linear guide rod 3 with rotational force. The protective frame 9 can protect the sub-gear 8 and the main gear 7, making the rotation of the sub-gear 8 and the main gear 7 more stable, which can solve the problem of manual real-time adjustment of the vacuum value during the evaporation loss measurement process, greatly saving manpower and time costs.
