When the free end of the support foot 2 is fully unfolded, the support foot 2 is used to support the main rod 1, and the main rod 1 can be connected with a shooting device, a mobile phone, a light supplementing lamp and the like. Therefore, the support foot 2 is relatively common in the scene of live broadcast and shooting. After use, the free end of the support foot 2 can be folded on the main rod 1, so as to facilitate carrying. In order to prevent the free end of the support foot 2 from being accidentally opened under the action of gravity or external force after being folded on the main rod 1, a convex point or a concave groove is arranged on the support foot 2, and a concave groove or a convex point structure matched with the support foot 2 is arranged at the bottom of the main rod 1, so as to ensure that the support foot 2 cannot be opened at will after being folded on the main rod 1. However, such a structure needs to manually and forcibly separate the support foot 2 and the main rod 1 when the support foot 2 is used again, which is laborious and troublesome.

[0046] In order to solve the above problems, the utility model provides a support foot 2 frame convenient to unfold, referring to Figure 1 and Figure 2 It includes

[0047] The main rod 1;

[0048] The support foot 2 supporting the main rod 1, the support foot 2 can be unfolded or folded, and the support foot 2 is close to the main rod 1 when being folded, and supports the main rod 1 when being unfolded;

[0049] The locking assembly 3 is used to limit the movement of the support foot 2 relative to the main rod 1 when the support foot 2 is folded, and the locking assembly 3 releases the limitation after being triggered, so that the support foot 2 is in an unfolded state or an unfoldable state.

[0050] Referring to Figure 3 and Figure 4The locking assembly 3 comprises a clamping structure 33 and a trigger button 31, and the trigger button 31 is provided with a pressing block 311; when the support leg 2 is folded, the clamping structure 33 is used for adapting to the support leg 2 and limiting the movement of the support leg 2 relative to the main rod; the pressing block 311 extrudes the support leg to separate the support leg 2 from the clamping structure 33 when the trigger button 31 is stimulated.

[0051] Compared with the prior art manual forced unfolding of the support leg 2, the support leg 2 is directly extruded by the movement of the pressing block 311 to separate the support leg 2 from the clamping structure 33, the limitation on the support leg 2 is removed, and the structure design is ingenious; the locking assembly 3 removes the limitation on all the support legs 2 after being triggered, so that the support legs 2 are in an unfolded / expandable state; and the support legs 2 are more convenient and labor-saving to open compared with manual forced opening.

[0052] In the embodiment, the number of support legs of the support leg 2 frame is 3, but should not be construed as being limited thereto, and can also be 4, 5 or other numbers.

[0053] In the embodiment, the stimulation mode of the trigger button 31 includes pressing, rotating or hitting, but is not limited thereto.

[0054] Referring to Figures 5-8 The clamping structure 33 comprises a first protrusion 331, and the support leg 2 is provided with a second protrusion 21; when the clamping structure 33 is adapted to the support leg 2, the first protrusion 331 and the second protrusion 21 abut against each other; the rotation of the support leg 2 is limited; wherein the abutment surface of the first protrusion 331 or / and the second protrusion 21 is a slope; when the pressing block 311 extrudes the support leg 2, the first protrusion 331 and the second protrusion 21 move along the slope; so that the support leg 2 is separated from the clamping structure 33; the design of the abutment surface as a slope ensures that the first protrusion 311 and the second protrusion 21 can be smoothly separated when the pressing block 311 extrudes the support leg 2.

[0055] In the embodiment, the number of the first protrusion 311 and the second protrusion 21 can be multiple.

[0056] In the preferred scheme, the support leg 2 is further provided with a first elastic sheet 22, one end of the first elastic sheet 22 is connected with the support leg 2, and the other end is suspended, and is used for abutting against the side wall of the trigger button 31; in the preferred scheme, the first elastic sheet 22 is a V-shaped elastic sheet, and one end of the V-shaped elastic sheet is fixedly connected with the support leg 2; compared with a linear elastic sheet, the V-shaped elastic sheet has higher strength and can bear greater elastic force; so that the V-shaped elastic sheet is not easy to break when being extruded by the pressing block.

[0057] In the embodiment, the first elastic sheet 22 is deformed when being pressed by the trigger button 31, and provides a force to the extrusion block 311 to push the support leg 2. Compared with the structure in which the first elastic sheet 22 is directly formed as an inclined surface, the first elastic sheet 22 can be deformed more when being compressed, and can provide a greater pushing force to push the support leg 2 after the trigger button 31 is unlocked. In addition, the user has a better feeling when pressing the trigger button 31 to unlock.

The extrusion block 311 pushes the support leg 2, and the clamping structure 33 is released from the restriction on the support leg.

[0060] In the embodiment, the trigger button drives the extrusion block to move and is released from the restriction, thereby avoiding forcibly separating the support leg 2 and the main rod 1 by using a greater force.

[0061] In the embodiment, one end of the fixed seat 32 is connected with the main rod 1, and the other end is provided with a groove. One end of the second elastic member 34 is accommodated in the groove and abuts against the bottom of the groove. The other end of the second elastic member 34 is sleeved with or abuts against the trigger button 31. When the trigger button 31 is pressed, the second elastic member 34 is compressed, the trigger button 31 is displaced and drives the extrusion block 311 to move. After the trigger button 31 is released, the trigger button 31 drives the extrusion block 311 to return to the initial position under the action of the second elastic member 34, and the trigger button 31 can be pressed again.

[0062] The fixed seat 32 can be an integral structure with the main rod 1, or can be two independent structures connected together by bonding, bolts or the like. The second elastic member 34 can be a spring or an elastic sheet.

[0063] In the specific scheme, the clamping structure 33 further includes a limiting cover 332, and the first protrusion 331 is arranged on the limiting cover 332. The limiting cover 332 is arranged above the groove of the fixed seat 32 and forms an accommodation space with the groove of the fixed seat 32. One end of the trigger button 31 extends into the accommodation space, and the trigger button 31 moves in the accommodation space after being stimulated.

[0064] In the embodiment, the second elastic member 34 is located in the accommodating space; and the cross section of the accommodating space is slightly larger than that of the second elastic member 34, so as to ensure that the elastic member 34 can only be compressed or stretched along its own axis; and preferably, the second elastic member 34 is a spring.

[0065] In the embodiment, the top of the end of the trigger button 31, which is not sleeved with the second elastic member 34, is provided with a pressing cap, so as to facilitate pressing or receiving external stimulation.

[0066] Referring to Figure 5 and Figure 6 , the end of the trigger button 31, which is sleeved with the second elastic member 34, is provided with an extension 313, the extension 313 surrounds the trigger button 31 in the axial direction, and the second elastic member 34 and the extension 313 abut against each other; and the extension 313 is used to abut against the limiting cover 332 or the fixing seat 32, so as to limit the displacement of the trigger button 31 in the accommodating space.

[0067] In the embodiment, the first protrusion 331 includes an inner inclined surface and an outer inclined surface; when the clamping structure 33 is adapted with the support leg 2, the surface of the first protrusion 331, which abuts against the second protrusion 21, is the inner inclined surface 3311 of the first protrusion 331; that is, the surface facing the trigger button 31 is the inner inclined surface 3311, and the surface not facing the trigger button 31 is the outer inclined surface 3312; when it is needed to fold the support leg 2, the support leg 2 is directly manually rotated to approach the main rod 1; in the folding process, first, the second protrusion 331 abuts against the first protrusion 21; then, with a slight force, the second protrusion 21 slides along the outer inclined surface of the first protrusion 331, and passes over the highest point of the first protrusion 331, and then abuts against the inner inclined surface 3311 of the first protrusion 331 again; at this time, the first elastic sheet 22 abuts against the side wall of the trigger button 31, and the first elastic sheet 22 is deformed, so as to provide a pushing force for unlocking and opening the support leg.
