Inside the base 1, a bracket 2 is fixedly connected through a bearing. On the top of the base 1, a protective sleeve 20 is fixedly connected. The inner wall of the protective sleeve 20 contacts the surface of the bracket 2. By providing the protective sleeve 20, the bracket 2 can be limited, improving the stability of the bracket 2 during rotation; on the surface of the bracket 2, a placement sleeve 3 is fixedly connected. On the right side of the base 1, a fixed box 4 is fixedly connected. On the top of the fixed box 4, a pedal 5 is hinged through a shaft rod. On the top of the pedal 5, a rubber pad 17 is fixedly connected. The number of rubber pads 17 is several. By providing the rubber pad 17, the top of the pedal 5 can be protected, facilitating the user to press the pedal 5; at the bottom of the pedal 5, an arc-shaped toothed plate 6 is fixedly connected. On the left side of the arc-shaped toothed plate 6, a positioning plate 18 is fixedly connected. The top of the positioning plate 18 contacts the inner wall of the fixed box 4. By providing the positioning plate 18, the arc-shaped toothed plate 6 can be limited, preventing the arc-shaped toothed plate 6 from moving too far.

[0033] The bottom end of the arc-shaped toothed plate 6 penetrates into the interior of the fixed box 4. On the top of the inner wall of the fixed box 4, a concave toothed rod 7 is fixedly connected through a bearing seat. The arc-shaped toothed plate 6 meshes with the concave toothed rod 7. Inside the fixed box 4, a clamping plate 8 is provided. On the right side of the clamping plate 8, a sleeve plate 9 is fixedly connected. On the right side of the sleeve plate 9, a second elastic piece 19 is fixedly connected. The right end of the second elastic piece 19 is fixedly connected inside the fixed box 4. By providing the second elastic piece 19, the sleeve plate 9 and the clamping plate 8 can be pushed, improving the reset speed of the clamping plate 8; the sleeve plate 9 is slidably sleeved on the surface of the concave toothed rod 7. At the bottom of the surface of the bracket 2, a card slot 10 is provided. The left end of the clamping plate 8 penetrates into the interior of the card slot 10. On the top of the fixed box 4, a first elastic piece 11 is fixedly connected. The top of the first elastic piece 11 is fixedly connected to the bottom of the pedal 5.

[0034] Refer to Figures 1-3 , on the surface of the base 1, a support assembly is provided. The support assembly includes a square sleeve 12. The square sleeve 12 is fixedly connected to the front and back of the base 1. Inside the square sleeve 12, a trapezoidal plate 13 is slidably connected. On the top of the square sleeve 12, a screw rod 14 is threadedly connected. The bottom end of the screw rod 14 extends into the interior of the trapezoidal plate 13. By providing the cooperation of the square sleeve 12, the trapezoidal plate 13 and the screw rod 14, the base 1 can be supported, increasing the contact area between the base 1 and the ground and improving the stability of the base 1. At the bottom of the trapezoidal plate 13, a baffle 15 is fixedly connected. The baffle 15 is slidably connected inside the square sleeve 12. By providing the baffle 15, the trapezoidal plate 13 can be limited, avoiding the trapezoidal plate 13 from detaching from the square sleeve 12.

[0035] Refer to Figures 3-4, a limiting component is arranged inside the fixed box 4. The limiting component includes a limiting plate 16 which is fixedly connected inside the fixed box 4, and the bottom of the limiting plate 16 contacts the top of the clamping plate 8. By arranging the limiting plate 16, the clamping plate 8 can be limited, improving the stability of the clamping plate 8 during movement.

[0036] Working principle: The user first hangs some laboratory instruments on the surface of the bracket 2, and then places some laboratory instruments inside the placement sleeve 3. When the bracket 2 needs to be rotated, step on the pedal 5 downward. The pedal 5 drives the arc-shaped toothed plate 6 to move downward. The arc-shaped toothed plate 6 drives the concave-shaped toothed rod 7 to rotate. While the concave-shaped toothed rod 7 slides inside the sleeve plate 9, it will push the sleeve plate 9 to move to the right. The sleeve plate 9 drives the clamping plate 8 to disengage from the card slot 10. Then rotate the placement sleeve 3. The placement sleeve 3 drives the bracket 2 to rotate. After reaching the appropriate angle, release the pedal 5. The elastic piece drives the pedal 5 and the arc-shaped toothed plate 6 to reset. The arc-shaped toothed plate 6 drives the clamping plate 8 to be inserted into the inside of the card slot 10 through the concave-shaped toothed rod 7, so as to fix the bracket 2, and then the instruments at the appropriate position can be taken, thus achieving the effect of convenient access to the instruments.
