The biaxial pivoting device according to claim 11, wherein the adjusting member comprises a threaded member that cooperates with a threaded hole on the pivoting seat, and one end of the threaded member is fixedly connected to the screwing member provided at the In the torque wrench outside the pivot seat, the other end of the threaded member is connected to the locking member.
16. The biaxial pivoting device according to claim 11, wherein the second component locking mechanism further comprises:

    A guide sleeve fixedly connected to the pivot seat;

    A wedge block slidable in the guide sleeve, the wedge block being arranged between the adjustment member and the lock member and configured to be formed with the lock member when pressed The wedge surface fits the locking member at its compressed position.
17. The biaxial pivoting device according to claim 16, wherein the wedging block is provided with a first concave-convex fitting structure, and the locking member is provided with a second concave-shaped fitting with the first concave-convex fitting structure. The concave-convex mating structure makes the wedge block relatively non-rotatable relative to the locking member.
18. The biaxial pivoting device according to claim 16 or 17, wherein at least one of the pivot body, the locking member, and the wedge block is at least partially made of a material selected from the group consisting of Made of: nylon, aluminum alloy, steel and polyacetal resin.
19. A frame assembly comprising a first part and a second part that are pivotably connected via a biaxial pivot device, wherein the biaxial pivot device is any one of claims 1-18 Biaxial pivoting device.
20. A stabilizer includes a pan-tilt for fixing a photographing device and adjusting the attitude of the photographing device, and a rack assembly for supporting the pan-tilt, wherein the rack assembly is as claimed in claim 19 Rack components.
