[0094] Among them, the two ends of the transmission member 221 can be detachably connected to the connecting member 433 and the clamping member 52 by means of threaded connection, but not limited to, so that the three can be connected to form an integrated structure and move synchronously in the axial direction of the support leg 20; the abutment section can be but not limited to being set in a spherical shape, and the connecting member 433 can be provided with an annular groove corresponding to the abutment section that is adapted to the shape of the sphere, so that when the abutment section moves linearly in the arrangement direction of the buckle body 431 and the pressure block 42, the annular groove on the connecting member 433 can be progressively matched with the abutment section, and as the sphere moves, the depth of the sphere entering the annular groove will also change, which can then drive the height position of the connecting member 433 overlapped with the sphere to change.

[0095] Specifically, when the buckle body 431 of the locking assembly 43 rotates, the connecting rod 432 moves linearly along the arrangement direction of the buckle body 431 and the pressure block 42, so that the abutment section and the connecting member 433 move relative to each other. At this time, the cross-sectional area of ​​the abutment point between the abutment section and the connecting member 433 will also change, that is, the height dimension of the abutment point between the abutment section and the connecting member 433 will change, so that the connecting member 433 resting on the abutment section can move in the vertical direction, and then drive the transmission member 221 connected to the connecting member 433 to move in the vertical direction synchronously, so as to further drive the clamping member 52 connected to the other end of the transmission member 221 to move in the vertical direction synchronously. Therefore, while the buckle body 431 rotates forward or reversely to lock or release the upper rod 21 of the first connecting seat 40, the clamping member 52 can synchronously move toward or away from the first connecting seat 40 to lock or release the lower rod 23 of the second connecting seat 50, thereby achieving synchronous locking and release of the first connecting seat 40 and the second connecting seat 50, which is beneficial to improving the ease of use of the support frame 100.
