[0068] Figure 3 It is an exemplary schematic diagram of a rotation slope and a rotation groove according to some embodiments of the present specification. Figure 4 is an exemplary schematic diagram of a rotating groove according to some embodiments of this specification

[0069] In some embodiments, Figure 3 and Figure 4 As shown, the rotation ramp may include two arcuate slopes 32, and the rotation groove may include two arcuate grooves 64. When the ball head is locked, the two arcuate slopes 32 fit with the two arcuate grooves 64, and the projections of the two arcuate slopes 32 and the two arcuate grooves 64 in the vertical direction coincide with each other.

[0070] In some embodiments, Figure 3 As shown, the arcuate slope 32 can be disposed on the upper surface of the base pad 3 and disposed at the periphery of the second groove 31. In some embodiments, the two arcuate slopes 32 can be disposed symmetrically relative to the center point of the base pad 3.

[0071] In some embodiments, Figure 4 As shown, the arc groove 65 can be arranged on the lower surface of the first groove and arranged on the periphery of the protruding section 64. In some embodiments, the two arc grooves 65 can be arranged symmetrically relative to the center point of the base pad 3, and the depth of the arc groove 65 can be the same as the height of the arc slope 32 to achieve fit. In some embodiments, the arc groove 65 can be gradually recessed in the vertical upward direction and around the protruding section 64.

[0072] Locking the ball head means fixing the position of the ball head in the cavity formed between the base pad and the base cover. Loosening the ball head means that the upper part of the ball head is separated from the cavity formed between the base pad and the base cover.

[0073] In some embodiments, when the ball head 7 needs to be locked, the ball head 7 is placed in the first groove 63, and the adjusting handle 6 can be rotated relative to the base. At this time, the rotating groove and the rotating slope gradually fit together during the rotation process. When the adjusting handle 6 is rotated until the rotating groove and the rotating slope are completely fitted together, the two arc-shaped inclined surfaces 32 coincide with the projections of the two arc-shaped grooves 65 in the vertical direction. At this time, the protruding section 64 is inserted into the second groove 31, and the lower surface of the main body 61 contacts the upper surface of the base pad 3. The adjusting handle 6 is fixed in the cavity, that is, the ball head 6 is fixed in the cavity.

[0074] In some embodiments, when the ball head 7 needs to be loosened, the adjusting handle 6 can be rotated relative to the base. At this time, the rotating groove and the rotating ramp are gradually separated during the rotation process. When the adjusting handle 6 is rotated until only the lower end of the rotating groove is in contact with the upper end of the rotating ramp, the protruding section 64 is disengaged from the second groove 31, the upper surface of the main body 61 contacts the lower surface of the second cone 12, and the upper half of the ball head 7 passes through the first opening 13 and is disengaged from the cavity.

[0075] In some embodiments of the present specification, the rotation of the adjustment handle can be converted into an up and down movement of the adjustment handle through the cooperation of the rotation groove and the rotation ramp, thereby simplifying the operation of locking or loosening the ball head.

[0076] In some embodiments of the present specification, the ball head universal fastening device can enable the user to more conveniently lock or loosen the universal ball head by rotating the adjustment handle, while avoiding the inconvenience that may be caused to the user by the need to use tools.

[0077] Furthermore, certain features, structures or characteristics in one or more embodiments of this specification may be appropriately combined.
