[0002] The existing quick release support generally adopts split type thread locking structure, and its core components include a fixed seat, a screw rod, a movable seat and a knob. The fixed seat is fixed to the bicycle frame by bolts or clamps. One end of the screw rod is directly sleeved in the through hole of the fixed seat, and only relies on the gap cooperation between the hole wall and the outer wall of the screw rod to realize non-rigid connection. The other end of the screw rod penetrates through the movable seat and is threadedly connected with the knob. The movable seat is used for bearing the camera, and the clamping force between the movable seat and the fixed seat depends on the axial pressure generated when the knob is tightened. Users can replace different movable seats to adapt to the connection of different accessories.

[0003] However, the movable seat needs to be completely unscrewed from the knob. At this time, the screw rod loses the axial constraint of the knob and is difficult to maintain positioning only relying on the gap cooperation with the fixed seat. It is easy to fall off from the through hole, especially in the outdoor riding scene. Once such small accessories are lost, it is difficult to find them, which affects the reusability of the equipment. SUMMARY

The locking block is located on one side of the hinge part and can swing and position relative to the hinge part. The locking block is used for mounting a sports camera. One end of the knob is coaxially fixed with a screw rod. The screw rod penetrates through the locking block and is threadedly connected with the hinge part. The screw rod constitutes the swing shaft of the locking block. Rotating the screw rod can apply axial pressure to the locking block or release the pressure.

[0006] Preferably, the screw rod is an external hexagonal bolt, which is coaxially sleeved on the knob, and the head of the screw rod is fixedly embedded in the tail end wall of the knob.

[0007] Preferably, the knob is columnar, and the two sides of the knob are symmetrically provided with finger turning structures.

[0008] Preferably, the hinge part and the locking block are provided with sawtooth structures on the opposite side walls, and the two sawtooth structures can be engaged with each other.

[0009] Preferably, a gasket is further sleeved on the screw, and the gasket is located between the locking block and the knob to increase the friction between them.

[0010] Preferably, an embedded groove is formed on an end wall of the locking block facing the knob, and the gasket is partially embedded in the embedded groove.

[0011] Preferably, the quick release support further comprises a pad, a through connection hole is arranged at the connecting portion, an axis of the connection hole is perpendicular to an axis of the screw, the pad is arranged below the connecting portion, a top of the pad protrudes to form an adapter protrusion, the adapter protrusion is rotationally connected to a lower end of the connection hole, a through hole is arranged at a top end of the adapter protrusion and penetrates a bottom wall of the pad, the through hole corresponds to the connection hole, and an anti-skid gasket is arranged at a bottom of the pad.
