[0033] The present invention proposes a detachable support leg. Referring to Figures 1 to 3, the present invention proposes a detachable support leg for supporting the support leg. The support leg can be used for photographic and video equipment. The photographic and video equipment is used to support photographic and video equipment. The photographic and video equipment includes electronic products such as mobile phones, cameras, and monitors. The photographic and video equipment includes photographic accessories such as monopods and tripods that require support legs. Taking the tripod as an example below, the detachable support leg includes a base 10, a driving member 20, a reset elastic member 30 and a foot nail member 40. The driving member 20, the reset elastic member 30 and the foot nail member 40 are all installed on the base 10. The foot nail member 40 is used to externally connect the support leg. The driving member 20 is pivotally connected to the base 10. The driving member 20 includes a pressing portion 21 and a hook 22. The driving member 20 is movable between a first position and a second position.

[0034] The base 10 has a flat bottom surface and is designed for use on smooth surfaces, effectively preventing the tripod from slipping. The foot spikes 40 are designed for use outdoors on rougher surfaces. The underside of the foot spikes 40 is provided with two tapered corners 42 spaced apart. These corners secure the tripod during use, preventing slipping. Existing tripods are inconvenient to switch between horseshoe and spikes, requiring manual bending and effort for each conversion. In this embodiment, after assembly, the drive member 20 is in the first position, the hook 22 is engaged with the foot spike 40, and the foot spike 40 cannot be removed from the base 10.

[0035] During the process of the driving member 20 moving from the first position to the second position, when the pressing part 21 is actuated, the driving member 20 rotates toward the second position, the reset elastic member 30 is stretched to generate a restoring force, and the hook 22 gradually disengages from the foot nail member 40. The driving member 20 is in the second position, and the hook 22 is separated from the foot nail member 40, so that the foot nail member 40 can be removed from the base 10. At this time, the reset elastic member 30 applies a force to the driving member 20 to restore it to the first position. After releasing the pressing part 21, the reset elastic member 30 drives the driving member 20 to reset. The user can directly step down on the pressing part 21 with his foot, so that the foot nail member 40 cannot be removed from the base 10, thereby realizing the conversion of the support leg from a horseshoe to a foot nail mode. It is flexible to use and does not require bending over for manual operation, saving time and effort (easy to operate), and improving user experience.

[0036] In some embodiments, referring to Figures 3 to 6 , the foot member 40 is rotatably connected to the base 10 via a rotating shaft 41. The hook 22 has a hook groove (not shown) that matches the rotating shaft 41. The hook groove faces different directions when the driving member 20 is in the first position and the second position, allowing the hook 22 to have a hooked state and a disengaged state with the rotating shaft 41. The rotating shaft 41 can be matched with one, two, or more hooks 22.

[0037] In some embodiments, referring to Figures 4 and 6, the base 10 is recessed with a mounting groove 11, and the two ends of the rotating shaft 41 are respectively rotatably connected to the two inner groove walls of the mounting groove 11. The pressing portion 21 is located outside the mounting groove 11 to facilitate user foot-operated or foot-stepping start. One end of the reset elastic member 30 is connected to the inner groove wall of the mounting groove 11, and the other end is fixedly connected to the driving member 20.

[0038] In this embodiment, the reset elastic member 30 can be a spring or an elastic material, such as silicone. Referring to Figures 2 and 5, specifically, the reset elastic member 30 is made of elastic silicone material. The reset elastic member 30 includes an extension portion 31, a first circular portion 32 and a second circular portion 33. The first circular portion 32 is protruding at one end of the extension portion 31, and the second circular portion 33 is protruding at the other end of the extension portion 31. The inner groove wall of the mounting groove 11 is recessed with a first circular limiting groove 12 that matches the first circular portion 32, and the driving member 20 is recessed with a second circular limiting groove 24 that matches the second circular portion 33. During the movement of the driving member 20 from the first position to the second position, the extension portion 31 of the reset elastic member 30 is stretched to generate a restoring force. The first circular portion 32 and the second circular portion 33 prevent the extension portion 31 from being disengaged from the first circular limiting groove 12 and the second circular limiting groove 24 respectively when being stretched. The structure is simple and easy to install.

[0039] In some embodiments, referring to Figures 2 and 5, in order to improve the stability of the installation and use of the reset elastic member 30, the extension portion 31 can be arranged in an elongated shape, the first circular limiting groove 12 is connected to the first elongated groove, and the first elongated groove is provided with an opening at one end away from the first circular limiting groove 12; and / or the second circular limiting groove 24 is connected to the second elongated groove 25, and the second elongated groove 25 extends out of the side of the driving member 20 at one end away from the first circular limiting groove 12. At least one end of the extension portion 31 connected to the first circular portion 32 is limited and accommodated in the first elongated groove; or one end of the extension portion 31 connected to the second circular portion 33 is limited and accommodated in the second elongated groove 25; or both ends of the extension portion 31 are respectively limited in the first elongated groove and the second elongated groove 25, and the extension portion 31 passes through the side openings of the first elongated groove (not marked) and the second elongated groove 25. The extension portion 31 can be installed from the upper openings of the first circular limiting groove 12, the first elongated groove, the second circular limiting groove 24, and the second elongated groove 25 for easy operation.

[0040] In some embodiments, in order to improve the stability of the foot nail member 40, the two ends of the rotating shaft 41 are respectively located on both sides of the foot nail member 40, and the two ends of the rotating shaft 41 respectively pass through the hook groove and are rotatably connected to the inner groove wall of the installation groove 11. The rotating shaft 41 and the foot nail member 40 can be set as one piece or separately. The two ends of the rotating shaft 41 can be hooked by two hooks 22 to improve the service life. Specifically, the driving member 20 includes two connecting parts 23. The outer side surface of the first end portion of the connecting part 23 is rotatably connected to the inner groove wall of the installation groove 11 through the shaft rod 26, that is, the connecting part 23 faces the inner groove wall of the installation groove 11. One side has a shaft 26. The second end of the connecting portion 23 extending upward has a hook 22. The third end of the connecting portion 23 is fixedly connected to the pressing portion 21. The two connecting portions 23 are arranged in parallel, and a receiving space 27 is formed between the two connecting portions 23 to rotate and accommodate part of the foot nail member 40. The first end, second end, and third end of the connecting portion 23 form a triangular distribution. The second circular limiting groove 24 is located between the first end and the second end of the connecting portion 23, saving space and making the pressing operation time-saving and labor-saving. In order to reduce the occupied space and reduce weight, the edge of the connecting portion 23 can be recessed to form a weight-reducing groove. After assembly, the extension portion 31 is located on the lower side of the rotating shaft 41, making the connection tight and the structure compact. The reset elastic member 30 can be provided as an integral part or as a separate part.

[0041] In order to improve the rotation stability of the connecting part 23, a movable groove 14 is recessed in the inner groove wall of the mounting groove 11. The movable groove 14 is expanded, and the first end of the connecting part 23 rotates in the movable groove 14 to prevent the connecting part 23 from being over-pressed, thereby improving the user experience.

[0042] In some embodiments, referring to FIG6 , a support portion 13 is provided on the bottom wall of the mounting slot 11 to support the foot member 40 and reduce pressure on the rotating shaft 41. When the foot member 40 rotates, the bottom side of the foot member 40 slides along the top surface of the support portion 13. The bottom side of the foot member 40 is provided with two spaced-apart tapered corners 42. The bottom side between the two tapered corners 42 can be an arcuate surface, and the top surface of the support portion 13 is correspondingly concave to form an arcuate surface. The tapered corners 42 and the foot member 40 can be separate components. The foot member 40 has a sleeve portion on its top that connects to the support leg, and the support leg is inserted into the sleeve portion for a fixed connection.

[0043] In summary, after assembly, the driving member 20 is in the first position, the two hooks 22 are hooked with the two ends of the rotating shaft 41 of the foot nail member 40, and the foot nail member 40 cannot be removed from the base 10;

[0044] During the process of the driving member 20 moving from the first position to the second position, when the pressing part 21 is stepped on, the pressing part 21 drives the two connecting parts 23 to rotate around the shaft 26, so that the driving member 20 rotates to the second position. At this time, the two reset elastic members 30 are stretched to generate a restoring force, and the orientation of the hook 22 gradually changes, so that the hook 22 gradually disengages from the rotating shaft 41; when the driving member 20 is in the second position, the hook 22 is separated from the rotating shaft 41, so that the foot nail member 40 can be removed from the base 10. At this time, the reset elastic member 30 applies a force to the driving member 20 to restore it to the first position. After releasing the pressing part 21, the two reset elastic members 30 drive the two connecting parts 23 to rotate around the shaft 26 to drive the driving member 20 to reset. Of course, when the foot nail member 40 needs to be installed on the base 10, when the foot nail member 40 is slid into the base 10 from above, the two ends of the rotating shaft 41 slide along the upper surface of the two hooks 22, and the two connecting parts 23 rotate around the shaft 26, so that after the two ends of the rotating shaft 41 slide into the two hooks 22, the driving member 20 is reset, and the installation is convenient.

[0045] The present invention further provides a support leg with a foot, comprising a support leg portion and the aforementioned detachable support leg. The bottom end of the support leg portion is fixedly connected to the foot nail member 40, and the support leg portion is retractable.
