The driving gear 39 meshes and drives the gear ring 36 and the hollow turntable 34 to rotate along the annular rail. The gear ring 36 then meshes and drives the three driven gears 37 to rotate. Under the limiting action formed by the vortex line 35 and the vortex line groove, the L-shaped slide plate 32 is driven to slide inward along the T-shaped notch 31, and the U-shaped clamping plate 33 is driven to clamp and fix the gong and drum body 4. Step 2: When the height of the gong and drum body 4 is adjusted, under the driving action of the first motor 18, the motor shaft of the first motor 18 drives the first hollow worm 19 to rotate synchronously, and the first hollow worm 19 engages to drive the fixed worm wheel 15 and the fixed swing arm 14 to swing inwardly, and under the hinged action of the fixed swing arm 14 and the driven swing arm 17, the support plate 2, the fixed cylinder 3, and the gong and drum body 4 are driven to rise to a suitable position; Step 3: When the gong and drum body 4 is adjusted forward and backward, under the driving action of the third motor 26, the motor shaft of the third motor 26 drives the short connecting shaft 27, the second single ear seat 212, and the rectangular frame 28 to rotate, and synchronously drives the U-shaped bracket 29, the fixing tube 3, and the gong and drum body 4 to adjust forward and backward; Step 4: When the gong and drum body 4 is adjusted left and right, under the driving action of the second motor 23, the second motor 23 drives the long connecting shaft 24 and the second hollow worm 25 to rotate, and the second hollow worm 25 then meshes and drives the linkage worm wheel 211, the linkage shaft 210, the U-shaped bracket 29, the fixing tube 3, and the gong and drum body 4 to adjust left and right; Step 5: After the gong and drum body 4 is adjusted, the user uses the gong and drum body 4 to perform a talent show.

[0023] The present invention can not only enhance the stability of the bracket and ensure the stable placement and use of gongs and drums during opera performances by optimizing the matching mode of the connecting parts, but also facilitate and quickly perform assembly and disassembly, thus simplifying the process of stage arrangement.

Under the driving action of the fourth motor (38), the motor shaft of the fourth motor (38) drives the driving gear (39) to rotate synchronously. The driving gear (39) meshes and drives the gear ring (36) and the hollow turntable (34) to rotate along the annular rail. The gear ring (36) then meshes and drives the three driven gears (37) to rotate. Under the limiting action formed by the vortex line (35) and the vortex line groove, the L-shaped slide plate (32) is driven to slide inward along the T-shaped notch (31), and the U-shaped clamping plate (33) is driven to clamp and fix the gong and drum body (4); Step 2: When the height of the gong and drum body (4) is adjusted, under the driving action of the first motor (18), the motor shaft of the first motor (18) drives the first hollow worm (19) to rotate synchronously, and the first hollow worm (19) meshes to drive the fixed worm wheel (15) and the fixed swing arm (14) to swing inwardly, and under the hinged action of the fixed swing arm (14) and the driven swing arm (17), the support plate (2), the fixed cylinder (3) and the gong and drum body (4) are driven to rise to a suitable position; Step 3, when the gong and drum body (4) is adjusted forward and backward, under the driving action of the third motor (26), the motor shaft of the third motor (26) drives the short connecting shaft (27), the second single ear seat (212), and the rectangular frame (28) to rotate, and synchronously drives the U-shaped bracket (29), the fixing tube (3), and the gong and drum body (4) to adjust forward and backward; Step 4: When the gong and drum body (4) is adjusted left and right, under the driving action of the second motor (23), the second motor (23) drives the long connecting shaft (24) and the second hollow worm (25) to rotate, and the second hollow worm (25) then meshes and drives the linkage worm wheel (211), the linkage shaft (210), the U-shaped bracket (29), the fixing tube (3), and the gong and drum body (4) to adjust left and right; Step 5: After the gong and drum body (4) is adjusted, the user uses the gong and drum body (4) to perform a talent show.
