An annular linkage cavity is provided in the rotating table 4. A plurality of vertical screw barrels 5 are uniformly rotatably installed on the inner wall of the bottom of the annular linkage cavity. Vertical studs 6 are threadedly sleeved in the plurality of vertical screw barrels 5. A support ring 7 is fixedly installed on the top of the plurality of vertical studs 6. The top of the crucible body 2 is uniformly A plurality of positioning holes are provided, and positioning rods 11 are slidably installed in the plurality of positioning holes, and the plurality of positioning rods 11 are fixedly installed on the top of the support ring 7.

Synchronous gears 9 meshing with the linkage gear ring 8 are fixedly sleeved on the plurality of vertical screw barrels 5, and adjusting hand wheels 10 are fixedly sleeved on the plurality of vertical screw barrels 5. An angle adjustment unit for fixing the rotating ring 3 is provided on the device base 1, and a fixing component for fixing one of the vertical screw barrels 5 is provided on the rotating table 4.

[0024] By means of the above structure, when one of the adjusting hand wheels 10 is rotated, one of the vertical screw barrels 5 and one of the synchronous gears 9 will be driven to rotate together, and the rotation of one of the synchronous gears 9 will drive the linkage gear ring 8 to rotate, and the rotation of the linkage gear ring 8 will drive the remaining multiple synchronous gears 9 and the remaining multiple vertical screw barrels 5 to rotate synchronously, and the synchronous rotation of multiple vertical screw barrels 5 will drive the support ring 7 and the crucible body 2 to move up and down through the vertical stud 6, thereby achieving the purpose of completing the adaptive adjustment of the height of the crucible body 2 at one time, and the operation is simple, easy to use and practical.

[0025] As a preferred implementation of this embodiment, the angle adjustment unit includes a control block 12 arranged just above the device base 1, a vertical plug rod 13 is fixedly installed at the bottom of the control block 12, a plug rod sliding hole connected to the annular rotating groove is opened at the top of the device base 1, a plurality of vertical plug holes are evenly opened at the top of the mounting swivel 3, the bottom end of the vertical plug rod 13 passes through the plug rod sliding hole and extends into one of the vertical plug holes, and an elastic reset element is installed on the control block 12. The advantage of this arrangement is that when the control block 12 is moved up and down, the vertical plug rod 13 will be driven to move in or out of the vertical plug hole, and then the mounting swivel 3 can be fixed or loosened. When the mounting swivel 3 is in a loose state, the rotating table 4 can be rotated to adjust the horizontal angle of the crucible body 2, thereby improving the application range of the device.

[0026] In this embodiment, the elastic reset element includes a reset tension spring 14 sleeved on the vertical plug rod 13, and the two ends of the reset tension spring 14 are respectively fixedly mounted on the top of the device base 1 and the bottom of the control pull block 12. The advantage of this arrangement is that when the control pull block 12 is released, the elastic force of the reset tension spring 14 will pull the control pull block 12 to automatically move downward, and then drive the vertical plug rod 13 to be inserted into the vertical plug hole, automatically fix the mounting swivel 3, and can always keep the fixed state, stable and reliable.

[0027] As a preferred implementation scheme of this embodiment, the fixing component includes a fixed gear 15 fixedly sleeved on the vertical screw barrel 5, a fixing plate 16 is fixedly installed on the top of the device base 1, a rotating hole is opened on the side of the fixing plate 16, a horizontal screw 17 is rotatably installed in the rotating hole, a movable screw barrel 18 is threadedly sleeved on one end of the horizontal screw 17, a fixed block 19 meshing with the fixed gear 15 is fixedly installed on one end of the movable screw barrel 18, a horizontal guide unit is installed on the fixed block 19, a hexagonal connecting rod 20 is fixedly installed on the other end of the horizontal screw 17, a control knob 21 is slidably sleeved on the hexagonal connecting rod 20, a blocking plate 22 is fixedly installed on the end of the hexagonal connecting rod 20, and a locking unit for fixing the control knob 21 is connected to the fixing plate 16.

Under the cooperation of the horizontal guide unit, the rotation of the horizontal screw 17 will drive the fixed block 19 to move horizontally through the movable screw barrel 18. When the fixed block 19 is moved to disengage from the fixed gear 15, the vertical screw barrel 5 can be loosened. When the fixed block 19 is moved to engage with the fixed gear 15, the vertical screw barrel 5 can be fixed. Therefore, during use, the height change of the crucible body 2 caused by accidentally touching the adjustment hand wheel 10 can be effectively reduced, and the stability during use is good.

The advantage of such a configuration is that when the control knob 21 is pulled, the locking rod 24 will be driven to move out of the locking hole, and the control knob 21 will be unlocked. At this time, the control knob 21 can be rotated to fix or loosen the vertical screw barrel 5. When the control knob 21 is loosened, the elastic force of the pressing spring 25 will squeeze and push the control knob 21 to automatically reset, and then the locking rod 24 can be driven to automatically insert into the locking hole, so that the control knob 21 is always locked and cannot be rotated, and the stability is better during use.
