[0043] The existing support foot usually comprises a main rod 1 and a support foot 2 for supporting the main rod 1, one end of the support foot 2 is rotatably connected with the main rod 1 or a connecting seat sleeved on the main rod 1, and the other end is a free end; when the free end of the support foot 2 is fully unfolded, the support foot 2 is used for supporting the main rod 1, and a shooting device, a mobile phone, a light supplementing lamp and the like can be connected on the main rod 1; 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 that the support foot 2 is convenient to carry; 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 the bottom of the main rod 1 is provided with a concave groove or a convex point structure matched with the support foot 2, so 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.

[0044] 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 , comprising

[0045] The main rod 1;

[0046] The support foot 2 for 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;

[0047] The locking assembly 3; the locking assembly 3 is used for limiting 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.

[0048] The locking assembly 3 comprises a trigger button 31, one end of which is provided with a clamping structure 312, and the other end is provided with a pressing block 311; the support leg 2 is provided with a first elastic sheet 22; when the support leg 2 is folded, the clamping structure 312 is matched with the support leg to limit the support leg 2; when the trigger button 31 is stimulated, the clamping structure 312 moves to release the limitation on the support leg 2; and the pressing block 311 presses the first elastic sheet 22 to make the support leg 2 move in the unfolding direction.

[0049] Compared with the prior art of manually unfolding the support leg 2 by force, the utility model releases the limitation on all the support legs 2 after triggering, so that the support legs 2 are in an unfolded / unfoldable state, which is more convenient and labor-saving than manually unfolding the support leg 2 by force.

[0050] In the application, the clamping structure 312 is driven by the trigger button 31 to move downward to release the limitation, which is a clever structure design; the first elastic sheet 22 is compressed by the pressing block 311 in the process of the movement of the trigger button 31, and the reaction force of the pressing block 311 on the first elastic sheet 22 makes the support leg 2 move away from the main rod 1, leave the locking position, and unfold by a certain angle; at this time, even if the trigger button 31 is released, the support leg 2 will not abut against the clamping structure 312 again, and the support leg is in an unfoldable state; it is convenient to complete the unfolding subsequently.

[0051] In the embodiment, the number of support legs of the support leg frame is 3, but it should not be understood as being limited to this, and it can also be 4, 5 or other numbers.

[0052] In the embodiment, the way of stimulating the trigger button 31 can be pressing or impact, but is not limited to this.

[0053] Referring to Figures 3-7 , the pressing block 311 is arranged at one end of the trigger button 2 away from the clamping structure, the clamping structure 312 releases the limitation on the support leg 2 when the trigger button 31 is pressed; at the same time, the pressing block 311 moves with the trigger button 31 to press the first elastic sheet 22, so that the support leg 2 moves in the unfolding direction; if the first elastic sheet 22 is replaced by a conventional non-elastic inclined surface, when the pressing block 311 presses the first elastic sheet 22, the non-elastic inclined surface can only elastically deform a little, and the thrust of the inclined surface on the support leg 2 is small; while the first elastic sheet 22 deforms greatly when it is pressed by the pressing block 311, the reaction force of the pressing block 311 on the first elastic sheet 22 is greater, and a greater thrust can be generated to push the support leg 2 more.

[0054] In the embodiment, the pressing block 311 protrudes from the side surface of the trigger button 31 and has an inclined surface inclined from the main rod 1 to away from the main rod 1; the inclined surface is used to guide the first elastic sheet 22 to move along the inclined surface when the pressing block moves.

[0055] In the embodiment, the first elastic sheet 22 is in an "L" shape structure, one end of the bottom of the "L" shape structure is connected with the supporting leg 2, and the upper part of the "L" shape structure is suspended and used to abut against the extrusion block 311; the suspended part of the upper part of the "L" shape structure can have a larger elastic deformation space, thereby generating greater elasticity; preferably, the upper part of the "L" shape structure is also designed as an inclined surface, which gradually inclines away from the bottom of the "L" shape structure from the bottom of the "L" shape structure. Since the extrusion block 311 gradually moves from the bottom of the "L" shape structure to the upper part of the "L" shape structure when extruding the first elastic sheet 22, the elastic force generated by the first elastic sheet 22 gradually increases, which means that the pushing force of the extrusion block 311 on the supporting leg 2 gradually increases during the pressing process, which is beneficial to unfolding the supporting leg 2.

[0056] Referring to Figures 3-7 In the embodiment, the locking assembly 3 comprises a fixing seat 32, a trigger button 31 and a second elastic member 34; the fixing seat 32 is connected with the main rod 1; the second elastic member 34 is arranged between the trigger button 31 and the fixing seat 32; and one end of the trigger button 31 is provided with a clamping structure, which is used to limit the movement of the supporting leg 2 relative to the main rod 1, that is, to limit the unfolding of the supporting leg 2; when the trigger button 31 is pressed, the clamping structure moves, thereby releasing the limitation on the supporting leg 2.

[0057] In the embodiment, the clamping structure 312 is moved by pressing to release the limitation, thereby avoiding forcibly separating the supporting leg 2 and the main rod 1 by using a larger force; and the structure design is ingenious. The fixing seat 32 can be an integral structure with the main rod 1 or can be two independent structures connected together by adhesion, bolts or the like; and the elastic member 34 can be a spring or an elastic sheet.

[0058] In the embodiment, one end of the fixing 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, and the other end 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 to drive the clamping structure 312 to move; after the trigger button 31 is released, the trigger button 31 drives the clamping structure to return to the initial position under the action of the second elastic member 34, and the trigger button 31 can be pressed again.

[0059] In the embodiment, in order to better limit the trigger button 1 to be compressed only in the axial direction, a limiting cover 33 is further arranged, the limiting cover 33 is arranged above the groove of the fixed seat 32, forms a containing space with the groove of the fixed seat 32, and the second elastic member 34 is located in the containing space; and the cross section of the containing space is slightly larger than that of the elastic member 34, so that the second elastic member 34 can be compressed or stretched only in the axial direction of itself; preferably, the second elastic member 34 is a spring; the limiting cover 33 in the embodiment is provided with an opening, and the end of the trigger button 31 which is not sleeved with the elastic member 34 passes through the opening; when the trigger button 31 is stimulated, the end of the trigger button 31 which extends into the containing cavity moves in the containing cavity.

[0060] The top of the end of the trigger button 31 which is not sleeved with the elastic member 34 is provided with a pressing cap for facilitating pressing.

[0061] In the embodiment, the end of the trigger button 31 which is sleeved with the second elastic member 34 is provided with an extension 313 which surrounds the trigger button 31 in the axial direction, and a clamping structure is arranged on the extension 313; when the trigger button 31 is compressed, the clamping part is driven to move in the direction of the compression elastic member 34; after the clamping part moves, the restriction on the supporting leg 2 can be released.

[0062] The clamping structure 312 is a first protrusion, the supporting leg 2 is provided with a second protrusion 21, the first protrusion and the second protrusion 21 abut each other to limit the movement of the supporting leg 2 relative to the main rod 1; when the trigger button 31 is pressed, the first protrusion moves downward and separates from the second protrusion 21, thereby releasing the restriction on the supporting leg 2; when the trigger button 31 is released, the first protrusion moves upward under the restoring force of the second elastic member 34 and returns to the original locking position. In the embodiment, the first protrusion passes through the limiting cover 33 when it is in the locking position, and is used to abut against the second protrusion 21.

[0063] In the embodiment, when it is needed to fold the supporting leg 2, the supporting leg 2 can be directly manually rotated to approach the main rod 1; during the folding process, the second protrusion 21 on the supporting leg 2 first moves along the inclined surface of the first protrusion, and presses the first protrusion downward; after the supporting leg 2 is completely folded, the first protrusion pops out and returns to the locking position, abuts against the second protrusion 21, and limits the unfolding of the supporting leg 2.

[0064] In the embodiment, the main rod 1 is provided with a connecting seat, one end of the supporting leg 2 is rotatably connected with the connecting seat 5, and the other end is a free end; when the free end of the supporting leg 2 is matched with the locking assembly 3, the supporting leg 2 is in the folded state; when the free end of the supporting leg 2 is not matched with the locking assembly 3, the supporting leg 2 is in the unfolded or unfoldable state; the connecting seat 5 can be sleeved on the main rod 1 and slides relative to the main rod 1.
