As shown in fig. 7, in particular, when the lock 410 is in the locked state, the lock 412 can be engaged with the sliding seat 210 to block the sliding seat 210 from moving relative to the central tube 100 and the sleeve 300 along the axial direction of the central tube 100, so as to lock the triangular support frame 200 in the sleeve 300 in the folded state.

As shown in fig. 7 and 8, the top end of the main body 411 is rotatably disposed on the sleeve 300, specifically, the top end of the main body 411 is rotatably disposed on the top end of the sleeve 300, a side surface of the main body 411 facing away from the sleeve 300 is a curved surface, and the thickness of the top end of the main body 411 is greater than that of the bottom end of the main body 411.

Through the arrangement of the second elastic member 430, the latch 410 is in a natural state (i.e. no external force acts on the latch 410), and the second elastic member 430 can drive the main body 411 to drive the latch portion 412 to rotate in a direction close to the through hole 320 under the action of its own elastic force, so that the latch portion 412 extends into the sleeve 300 through the through hole 320 and is clamped with the triangular support frame 200, so as to switch the latch 410 to a locking state, thereby locking the triangular support frame 200 in a folded state in the sleeve 300. In addition, when the latch 410 needs to be switched from the locked state to the unlocked state, the external force of the user overcomes the elastic force exerted on the main body 411 by the second elastic member 430, and drives the main body 411 to drive the latch part 412 to rotate in the direction away from the through hole 320, so that the latch part 412 extends out of the sleeve 300 through the through hole 320 and is separated from the triangular support frame 200.

As shown in fig. 9, further, the central tube 100 includes a plurality of connecting tubes 110 that are sequentially sleeved, wherein one connecting tube 110 can be extended and retracted relative to another connecting tube 110 that is adjacent to the other connecting tube 110 along the axial direction of the central tube 100, so that the supporting length of the central tube 100 is adjustable along the axial direction of the central tube 100. In particular, during photographing or filming, the height of the photographing apparatus on the top end of the center tube 100 is often required to be adjusted, and the height adjustment of the photographing apparatus on the top end of the center tube 100 can be realized by adjusting the supporting length of the center tube 100 through sequential sleeving between the plurality of connection tubes 110. In one embodiment, the top end of the center tube 100 is used to attach a pan/tilt head on which the photographic equipment can be mounted.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
