[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an adjustable hanger for graphite crucible, comprising a fixing box 1, the top left and right sides of the fixing box 1 are fixedly connected with a fixing frame 11, the inner side of the fixing frame 11 is fixedly connected with a fixing rod 12, the front and rear ends of the outer wall of the fixing rod 12 are provided with a torsion spring 10, the far ends of the torsion spring 10 are respectively fixedly connected to the front and rear sides of the inner wall of the fixing frame 11, the middle part of the fixing rod 12 is rotatably connected with a rotating plate 8, the adjacent ends of the torsion spring 10 are respectively fixedly connected to the middle parts of the front and rear sides of the rotating plate 8, the outer wall of the fixing box 1 is provided with a through hole 9, the bottom of the rotating plate 8 is fixedly connected with a buckle 7, the end of the buckle 7 passes through the through hole 9, and the inner side of the fixing box 1 is provided with a connecting mechanism 2;

[0031] Specifically, when the rotating plate 8 starts to rotate, the torsion spring 10 will be acted upon by a force and will begin to accumulate energy; this energy accumulation provides the necessary power for the subsequent flipping action; as the force on the torsion spring 10 continues to increase, it begins to release the stored energy and pushes the rotating plate 8 to flip; when the rotating plate 8 flips to the vertical direction, the buckle 7 originally fixed in the through hole 9 can be smoothly taken out, thereby canceling the original engaged state; at this time, the internally installed connecting structure can be easily taken out, completing the disassembly process of the sling; when the sling needs to be reinstalled or fixed, the operator only needs to loosen the rotating plate 8; at this time, the torsion spring 10 The potential energy accumulated in the torsion spring 10 begins to rebound and pushes the rotating plate 8 to flip and reset; as the rotating plate 8 is reset, the buckle 7 is inserted into the through hole 9 again, thereby fixing the connecting structure; this design is not only easy to operate, but also saves time and effort; it makes full use of the energy storage characteristics of the torsion spring 10, making the flipping process of the rotating plate 8 smoother and more efficient; at the same time, through the cooperation of the buckle 7 and the through hole 9, the stability and safety of the connecting structure are ensured; this design not only improves work efficiency, but also reduces the difficulty of operation; the operator does not need to use additional tools or equipment, and can complete the replacement or disassembly of the sling with simple operations.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The connecting mechanism 2 includes a horizontal bar 201, which is slidably connected to the inner side of the fixed box 1, a knob 202 is rotatably connected to the top of the horizontal bar 201, a worm 206 is fixedly connected to the bottom of the knob 202, a worm gear 205 is rotatably connected to the inner side of the horizontal bar 201, the knob 202 is meshed with the worm gear 205, a gear 204 is fixedly connected to the left side of the worm gear 205, a sawtooth bar 203 is slidably connected to the inner rear side of the horizontal bar 201, and the gear 204 The front side of the horizontal bar 201 is fixedly connected with a handle 4, and the front and rear sides of the fixed box 1 are fixedly connected with a connecting ring 3; the rear side of the horizontal bar 201 is fixedly connected with a slide bar 13, and the slide bar 13 is slidably connected with the rear side of the inner wall of the fixed box 1; the top of the knob 202 is provided with a square groove 17, and a rotating bar 18 is installed inside the square groove 17; the bottom of the sawtooth bar 203 is fixedly connected with a cross bar 15, and the outer wall of the cross bar 15 is provided with a horizontal hole 14;

[0033] Specifically, as the horizontal bar 201 moves, it cleverly drives the slide bar 13 to slide on the inner rear side of the fixed box 1; this design not only ensures the stability of the movement of the horizontal bar 201, but also plans its movement trajectory, thereby ensuring that it can be smoothly pushed out of the fixed box 1; next, it is necessary to take the rotating bar 18 and insert it into the square groove 17; this step is crucial because it lays the foundation for subsequent operations. After inserting the rotating bar 18, it can be rotated; as the rotating bar 18 rotates, it rotates together with the knob 202; this linkage design makes the operation more convenient and also enhances the stability of the overall structure; the rotation of the knob 202 further drives the synchronous rotation of the worm 206; the worm 206 and the worm wheel 205 work through precise meshing transmission, thereby driving the worm wheel 205 and the gear 204 to rotate; this transmission method not only has high transmission efficiency, but also can ensure the smoothness of operation; the rotation of the gear 204 further meshes with the sawtooth bar 203; this design enables the sawtooth bar 203 to slide down according to a predetermined trajectory; as the sawtooth bar 203 slides, it drives the hidden cross bar 15 to descend from the bottom of the cross bar 201; the realization of this process not only demonstrates the ingenuity of the design, but also reflects the exquisiteness of the technology; other slings can be connected through the horizontal hole 14 on the cross bar 15; this design makes the entire sling system highly flexible and scalable, and can meet the use requirements in different scenarios.

[0034] Reference Figure 1 and Figure 3 The top of the horizontal bar 201 is provided with a plurality of openings 16 at equal intervals, and the lower end of the buckle 7 is engaged with the opening 16; the bottom of the fixing box 1 is provided with a sling assembly 5, and the inner side of the sling assembly 5 is provided with a clamping plate 6;

[0035] Specifically, the horizontal bar 201 is fixed by snapping, and the graphite crucible is lifted by the cooperation between the lifting tool assembly 5 and the clamping plate 6 .

[0036] Working principle: When replacing or removing the external hanger for the graphite crucible, turn the rotating plate 8 to rotate, and the torsion spring 10 is subjected to force through the rotation of the rotating plate 8. The force of the torsion spring 10 is used to store energy, thereby driving the rotating plate 8 to flip, and the rotating plate 8 is flipped to the vertical direction, so that the buckle 7 is taken out of the through hole 9, the engaged state is cancelled, and the internally installed connection structure is taken out. When it needs to be fixed, the rotating plate 8 is released, and at the same time, the potential energy of the torsion spring 10 rebounds and drives the rotating plate 8 to flip and reset, so that the buckle 7 is inserted into the through hole 9, and the connection structure is fixed, which is more time-saving and labor-saving;

[0037] When connecting an external sling, the handle 4 is used to push the horizontal bar 201 to move. When the horizontal bar 201 moves, the slide bar 13 is driven to slide on the inner rear side of the fixed box 1, and the movement trajectory of the horizontal bar 201 is planned, so that the horizontal bar 201 is pushed out of the fixed box 1, and the rotating bar 18 is taken out and inserted into the square groove 17. The rotating bar 18 rotates the knob 202 together with the rotation of the knob 202, and the rotation of the worm 206 rotates synchronously. The rotation of the worm 206 is meshed with the worm wheel 205, thereby driving the worm wheel 205 and the gear 204 to rotate. The rotation of the gear 204 is meshed with the sawtooth bar 203, thereby driving the sawtooth bar 203 to slide down, and the sliding of the sawtooth bar 203 drives the hidden horizontal bar 15 to descend from the bottom of the horizontal bar 201, and other slings can be connected through the horizontal hole 14 on the horizontal bar 15.
