[0002] For example, U.S. Patent No. USD1026875 discloses a microphone arm having a fixed end and a free end. The fixed end is a clamping seat for clamping on a table edge or a flat plate, and the free end is a universal joint for locking a microphone clip to hold a microphone. A four-bar linkage structure is arranged between the clamping seat and the universal joint to provide various degrees of freedom for rotating the four-bar linkage structure to adjust the universal joint to a desired position.
[0003] Since the clamping seat support arm is a cantilevered multi-link structure, when the joints between the links have vertical rotation freedom, the joints will bear the rotation torque generated by gravity. Therefore, when the rotation torque borne by the joints exceeds the fixed torque of the joints, the links will be loose and the clamping seat support arm will be tilted, which may affect the use and cause damage to the equipment.

The first locking element 61 and the first pivoting hole 13 have a distance therebetween, so that a larger locking torque can be generated, and a larger rotating torque can be resisted without the problem of drooping.
[0023] In an embodiment, the first locking groove 14 is arranged on the upper side of the first pivoting hole 13, so that the first extension rod 20 can be limited to rotate relative to the first joint 10, and the first extension rod 20 can maintain horizontal when the first locking element 61 is loosened to avoid drooping.
[0024] The second joint 30 is provided with a second base 31, a second pivoting element 32, a second pivoting hole 33 and a second locking groove 34. The second pivoting element 32 is rotatably arranged on the second base 31. In an embodiment, the second base 31 is provided with a pipe body 311, and the second pivoting element 32 is provided with a column body 321. The column body 321 is rotatably arranged in the pipe body 311, and a pressing knob 81 is arranged through the pipe body 311 to tightly fix the column body 321.
[0025] The second pivot hole 33 is provided on the second pivot element 32, and the second locking slot 34 is provided on the second pivot element 32 and surrounds the second pivot hole 33.
