[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The arthroscopic tray device capable of multi-directional rotation not only realizes convenient angle adjustment, realizes convenient limiting, but also realizes convenient collection of pollutants;

[0012] (1) By providing a base body, a reserved groove, a rotary shaft and a worm gear, the rotary shaft in the rotary bracket assembly is inserted into the base body in the base assembly and is fixed by a circlip to limit the freedom of movement, so that the rotary bracket body can only rotate 360 degrees arbitrarily around the base bracket.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: Please refer to Figure 1-9 , an arthroscopic tray device that can rotate in multiple directions, including a tray main body 28 and a bracket assembly 29.

A worm gear 25 is installed outside the worm gear fixing shaft 24. A worm gear fixing key 26 is provided between the worm gear 25 and the worm gear fixing shaft 24. A bracket connecting block 9 is installed on the left side of the worm gear 25. A worm fixing shaft 23 is provided inside the rotating bracket main body 8. A worm fixing upper cover 21 is provided at the top end outside the worm fixing shaft 23. A worm 22 is provided outside the worm fixing shaft 23. A pitching hand-tightening screw 7 is provided on the right side inside the rotating bracket main body 8. A pitching screw fixing screw 19 is provided on the left side inside the rotating bracket main body 8. A worm fixing main body 20 is provided on the right side of the worm fixing upper cover 21;

[0027] The tray main body 28 and the bracket assembly 29 are locked tightly with screws at the bottom. The bottom tray 1 and the base main body 2 are fixed with screws. The base main body 2 and the base main body shielding block 3 are fixed with screws. At both ends inside the base main body 2, there are model pitch fixing screws 15. The bracket connecting block 9 is installed at both ends of the worm gear 25 through screws 27.

[0028] Specifically, as Figure 1 , Figure 2 , Figure 3 and 5 shown, the rotating shaft 17 in the rotating bracket assembly is inserted into the base main body 2 in the base assembly and fixed by a circlip to limit the degree of freedom of movement, so that the rotating bracket main body 8 can only rotate arbitrarily 360 degrees around the base bracket. The worm fixing main body 20 and the worm fixing upper cover 21 are fixed with screws. The worm fixing shaft 23 is sleeved on the worm 22, passes through the worm fixing main body 20 and the worm fixing upper cover 21, and is fixed by a circlip on the worm fixing shaft 23 to limit its degree of freedom of movement, assembling into a worm assembly. By rotating the hand-tightening screw 5, an extrusion force is generated between the hand-tightening screw 5 and the axial surface of the rotating shaft 17, so as to achieve the purpose of locking.

[0029] Embodiment 2: At the top inside the base main body 2, there is a worm fixing upper cover 21. At the top on the right side of the base main body 2, there is a rotating hand-tightening screw 5. At the bottom end of the rotating bracket main body 8, there is a rotating shaft 17. At the bottom end inside the rotating bracket main body 8, there is a rotating shaft fixing screw 18. At both ends of the rotating bracket main body 8, there are rotating bracket main body PVC sheets 14. Between the rotating bracket main body PVC sheet 14 and the rotating bracket main body 8, there is a bracket main body shielding block 6. On the outer side wall of the bracket main body shielding block 6, there is a limiting groove 601. On the left side of the bracket connecting block 9, there is a model fixing main body 13. At both ends of the model fixing main body 13, there are a left model fixing block 10 and a right model fixing block 11. Inside the left model fixing block 10 and the right model fixing block 11 respectively, there are model fixing hand-tightening screws 12.

[0030] Specifically, as Figure 1 , Figure 2 , Figure 3 and 5 shown, drive the worm 22 assembly to move forward, so that the worm gear 25 and the worm 22 are meshed. Since in the transmission of the worm 22 and the worm gear 25, when the worm gear 25 is the driving part, the worm 22 bears most of the load, while the worm gear 25 only plays an auxiliary role, due to reasons such as end cover friction and friction coefficient, the worm gear 25 cannot drive the worm 22 to rotate. Thus, when the worm gear 25 and the worm 22 are meshed, the purpose of locking and fixing the bracket assembly is achieved. When the user operator rotates the pitch hand-tightening screw 7 in the reverse direction, drive the worm 22 assembly to move in the reverse direction, so that the worm gear 25 and the worm 22 are disengaged, achieving the purpose of unlocking.

[0031] Embodiment 3: The left model fixing block 10 and the right model fixing block 11 are installed at both ends of the model fixing main body 13 through the model fixing hand-tightening screws 12. The rotating shaft 17 is arranged inside the worm fixing upper cover 21. The rotating shaft 17 is installed at the bottom end of the rotating bracket main body 8 through the rotating shaft fixing screw 18. A rotating bracket main body fixing screw 16 is arranged between the model fixing main body 13 and the bracket connecting block 9. The model fixing main body 13 is installed on the left side of the bracket connecting block 9 through the rotating bracket main body fixing screw 16.

[0032] Specifically, as Figure 6 shown, in related experiments such as animal experiments, it is necessary to use liquid cleaning experiments to facilitate perfusion cleaning and collect pollutants, which can not only reduce pollution but also facilitate cleaning.

[0033] Working principle: When in use, as Figure 4 shown, the worm wheel 25 and the bracket connecting block 9 are fixed by screws 27 to achieve the purpose of integration.

[0034] As Figure 3 , Figure 5 shown, the worm fixing main body 20 and the worm fixing upper cover 21 are fixed by screws. The worm fixing shaft 23 is sleeved on the worm 22, passes through the worm fixing main body 20 and the worm fixing upper cover 21, and a circlip is used to fix the worm fixing shaft 23 to limit its freedom of movement, and a worm assembly is assembled.

[0035] As Figure 3 , Figure 5 shown, the pitching hand-tightening screw 7 is passed through the rotating bracket main body 8 by threading.

[0036] As Figure 3 , Figure 4 , Figure 5 shown, the fixed worm assembly is placed inside the rotating bracket main body 8, and the worm assembly is connected to the rotating bracket main body 8 by using the pitching screw fixing screw 19, and the freedom of rotation of the worm assembly is restricted by the limiting groove 601 in the rotating bracket main body blocking block 6, so that the worm assembly cannot rotate around the pitching hand-tightening screw 7 and can only move back and forth.

[0037] As Figure 3 , Figure 5 shown, the assembled fixed bracket assembly is passed through the hole in the rotating bracket main body 8, and the fixed bracket assembly is connected to the rotating bracket main body 8 by using the worm wheel fixing shaft 24 and the worm wheel fixing key 26, and circlips are used to fix both ends of the worm wheel fixing shaft 24 to limit the freedom of movement of the fixed bracket assembly so that it can only rotate around the worm wheel fixing shaft 24.

[0038] As Figure 3 , Figure 5As shown, when the user operator rotates the pitch hand-tightening screw 7, it drives the worm assembly to move forward, thus enabling the worm wheel 25 and the worm 22 to mesh. Since in the transmission between the worm 22 and the worm wheel 25, when the worm wheel 25 is the driving part, the worm 22 bears most of the load, and the worm wheel 25 only plays an auxiliary role due to reasons such as the end cover friction and the friction coefficient, the worm wheel 25 cannot drive the worm 22 to rotate. Thus, when the worm wheel 25 and the worm 22 are meshed, the fixed bracket assembly is locked and fastened.

[0039] As Figure 3 , Figure 5 shown, when the user operator rotates the pitch hand-tightening screw 7 in the reverse direction, it drives the worm assembly to move in the reverse direction, causing the worm wheel 25 and the worm 22 to disengage from each other, achieving the purpose of unlocking.

[0040] As described in Point 5 above, the user operator only needs to apply a slight torque to achieve the purpose of labor-saving locking of the fixed bracket assembly end.

[0041] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
