Specifically, for example, an upper portion of the inner circumferential wall of the locking member 2 is provided with an internal thread, a lower portion of the inner circumferential wall of the locking member 2 is formed with a first locking portion 21, the internal thread and the first locking portion 21 are arranged in the vertical direction, an upper portion of the outer circumferential wall of the mounting plate 202, that is, an outer circumferential wall of the mounting plate body 2024 described above is provided with an external thread, a lower portion of the mounting plate 202, that is, a portion of the mounting plate 202 having the second gap 2023 (a structure defined by the plurality of connecting plates 2025 described above) is formed as a first locking inclined portion 2021, and the first locking inclined portion 2021 extends obliquely toward a direction close to the central axis of the mounting plate 202 in the vertical direction, so that, when the locking member 2 is rotated and the internal thread on the inner circumferential wall of the locking member 2 is gradually engaged with the external thread on the mounting plate 202, the first locking portion 21 comes into contact with the first locking inclined portion 1 as the thread moves upward, and applies a radially inward locking force to the first locking inclined portion 2021, the first locking inclined portion 2021 is caused to be in a deformed and contracted state, so that the first locking inclined portion 2021 applies a radially inward locking force to the support leg 1 and finally clasps the support leg 1 to limit the axial movement of the support leg 1, thereby achieving the purpose of locking.
In some embodiments of the present invention, the conical half angle of the first locking inclined portion 2021 is β, and β has a value in a range of: beta is more than 0 degree and less than or equal to 45 degrees. The first locking slope portion 2021 is formed in a truncated cone shape, and a half of a cone angle corresponding to the truncated cone is β. For example, β is 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 °, 9 °, 10 °, 11 °, 12 °, 13 °, 14 °, 15 °, 16 °, 17 °, 18 °, 19 °, 20 °, 21 °, 22 °, 23 °, 24 °, 25 °, 26 °, 27 °, 28 °, 29 °, 30 °, 31 °, 32 °, 33 °, 34 °, 35 °, 36 °, 37 °, 38 °, 39 °, 40 °, 41 °, 42 °, 43 °, 44 °, or 45 °. Therefore, the locking effect can be improved, and the purpose of locking can be realized under the action of a small locking force.
Alternatively, the conical half angle of the first locking inclined portion 2021 and the conical half angle of the first locking portion 21 are different. Specifically, the conical half angle of the first locking slope portion 2021 is smaller than that of the first locking portion 21. This is advantageous in achieving wire abutment between the first locking portion 21 and the first locking slope 2021, thereby improving the abutment effect.
Of course, the present invention is not limited thereto, and the conical half angle of the first locking inclination portion 2021 is equal to the conical half angle of the first locking portion 21. This is advantageous in achieving surface contact between the first locking portion 21 and the first locking inclined portion 2021, thereby improving the contact effect.

Wherein, the one end of turn-ups 221 links to each other with the lower extreme of the internal perisporium of retaining member 2 and the other end orientation is close to the direction extension of the central axis of retaining member 2, and butt plate 222 links to each other and upwards extends with the other end of turn-ups 221, and at the locking position, the lower extreme of mounting panel 202 is located between the internal perisporium of retaining member 2 and the periphery wall of butt plate 222, mounting panel 202 and butt plate 222 butt so that mounting panel 202 hugs closely supporting legs 1 through butt plate 222. Specifically, by rotating retaining member 2 to move retaining member 2 downward so that the inner peripheral wall of retaining member 2 is disengaged from the outer peripheral wall of mounting plate 202 (e.g., retaining member 2 is located below mounting plate 202), thereby being in the unlocked position, by rotating retaining member 2 to move retaining member 2 upward, retaining member 2 can be moved such that the lower end of mounting plate 202 is located between the inner peripheral wall of retaining member 2 and the outer peripheral wall of abutment plate 222, mounting plate 202 abuts abutment plate 222 to apply a radially inward locking force to abutment plate 222, thereby mounting plate 202 clasps abutment plate 222, abutment plate 222 deforms radially inward to apply a radially inward locking force to support foot 1, and finally clasps support foot 1 for the purpose of locking support foot 1. Thus, the structure is simple.

Specifically, since the second locking slope 2022 is inclined toward the direction close to the central axis of the mounting plate 202 in the direction from bottom to top, in the process of moving the locking member 2 upward from the unlocking position to the locking position, the first locking portion 21 gradually abuts against the abutment plate 222, so as to apply a radially inward locking force to the abutment plate 222 in the radial direction and in the direction close to the central axis of the mounting plate 202 and deform the abutment plate 222, so that the abutment plate 222 applies a radially inward locking force to the support foot 1 and finally embraces the support foot 1, thereby limiting the up-and-down movement (i.e., axial movement) of the support foot 1 and realizing the locking function. Therefore, the second locking inclined surface 2022 is arranged, so that the locking effect is good, and the purpose of locking under the action of a small locking force can be realized.
In some embodiments of the present invention, the second locking ramp 2022 has a cone half angle γ, where γ is in the range of: gamma is more than 0 degree and less than or equal to 45 degrees. That is, the second locking slope 2022 is formed in a truncated cone shape, and γ is a half of a conical angle corresponding to the truncated cone.
