[0005] The lifting mechanism comprises a limiting rod, a worm gear, a worm and a knob, the lower part of the limiting rod is slidably connected to the middle of the base, the outer periphery of the worm gear is rotatably connected to the upper part of the inner side of the base, the middle of the worm gear is threadedly connected to the outer periphery of the limiting rod, the outer periphery of the worm is rotatably connected to the inside of the base, the worm and the worm gear are meshed with each other, and the knob is fixedly connected to one end of the worm and penetrates the wall of the base.

[0006] Preferably, a plurality of suction cups are arranged on the lower part of the base.

[0007] Preferably, the supporting mechanism comprises a connecting ring, a groove, a sliding groove, a roller, a supporting seat and a traction assembly, a plurality of grooves are equidistantly arranged on the outer periphery of the connecting ring, the sliding grooves are arranged on the inner walls on the left and right sides of the grooves, the supporting seat is arranged in the inner part of the groove, the roller is arranged in the inner part of the sliding groove, the middle of the roller is connected to the supporting seat, the lower end of the supporting seat is connected to the traction assembly, the traction assembly is installed on the upper part of the limiting rod, and the lower part of the connecting ring is fixedly connected to the upper end of the limiting rod.

[0008] Preferably, a rubber film is arranged on the outer periphery of the upper part of the supporting seat.

[0009] Preferably, the number of supporting seats is at least three.

[0010] Preferably, the traction assembly includes a servo motor, a connecting rod, a T-ring, a gear, and a gear ring. One end of the connecting rod is rotatably connected to the lower part of the support base, and the other end of the connecting rod is rotatably connected to the outer circumference of the T-ring. The middle part of the T-ring is slidably connected to the outer circumference of the limiting rod. The gear ring and the gear are both rotatably connected to the lower part of the T-ring, and the gear and the gear ring mesh with each other. The gear ring is threadedly connected to the outer circumference of the limiting rod. The servo motor is installed on the upper part of the T-ring, and the lower output end of the servo motor passes through the side wall of the T-ring and is fixedly connected to the middle part of the gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The base restricts the limit rod, preventing it from rotating and allowing it to move up and down. By turning the knob, the worm gear drives the worm wheel to rotate, thus allowing the limit rod to move up and down. This facilitates the adjustment of the height of the support mechanism, making it convenient for people of different heights to use.

[0013] 2. By using multiple support bases arranged in a circle, the speaker body is placed within this circle, thus restricting the speaker body. A servo motor is driven, causing a gear to rotate a ring gear, which in turn causes the T-shaped ring to move up and down relative to the limiting rod. When the connecting rod moves upward, it causes the support bases to move outward, making the circle formed by the multiple support bases larger. When the connecting rod moves downward, it causes the support bases to move inward, making the circle formed by the multiple support bases smaller. This allows for the placement and fixation of speaker bodies of different sizes, facilitating use and improving processing efficiency. Attached Figure Description
