[0021] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-4 The diagram shows a fixed connection base for a triangular support frame, comprising a base 1. The upper surface of the base 1 has several connection holes 2 for connecting accessories. Several columns 3 are fixedly connected to the lower edge of the base 1. Each column 3 has a foot 4 rotatably sleeved on it. Each foot 4 includes a first mounting sleeve 5 rotatably sleeved on the column 3. The first mounting sleeve 5 is horizontally T-shaped. A connecting pipe 6 is inserted into the horizontal section of the first mounting sleeve 5. The other end of the connecting pipe 6 is inserted into a second mounting sleeve 7. A support foot 8 is inserted into the vertical section of the second mounting sleeve 7. A first movable handle 9 is screwed onto the outer circumference of the vertical section of the first mounting sleeve 5. A groove 301 is formed on the outer circumference of the column 3. The free end of the first movable handle 9 is screwed into the first mounting sleeve 5 and abuts against the outer circumference of the groove 301. The connection holes 2 on the surface of the base 1 are radially distributed, allowing for the replacement of corresponding connecting accessories according to the customer's photographic equipment accessories. Figure 4 As shown, ensure that the mounting hole position of the accessory corresponds to the connection hole 2 position on the surface of the base 1. At the same time, the rotatable setting of the foot body 4 can adjust the width of the support foot 8 from the center of the base 1.

[0023] Specifically, a second movable handle 10 is screwed onto the outer surface of the second mounting sleeve 7. The free end of the second movable handle 10 is screwed into the second mounting sleeve 7 and abuts against the outer circumferential surface of the support foot 8. The height of the support foot 8 is adjustable, allowing the photographic equipment to maintain a horizontal position even in uneven environments or environments with height differences.

[0024] Specifically, a first swivel post 11 is welded to the outer circumferential surface of the vertical section of both the first mounting sleeve 5 and the second mounting sleeve 7. The first swivel post 11 has an internal thread. The free ends of both the first movable handle 9 and the second movable handle 10 are integrally provided with threaded sections, which are screwed into the corresponding first swivel post 11. When the foot body 4 is rotated to adjust its left and right position, even when the first movable handle 9 is released, the threaded section at its free end remains partially within the groove 301 of the post 3, preventing the entire foot body 4 from detaching from the post.

[0025] Specifically, a second swivel post 12 is welded to the outer circumference of the horizontal section of both the first mounting sleeve 5 and the second mounting sleeve 7. The second swivel post 12 has an internal thread, and a set screw 13 is screwed into it. The free end of the set screw 13 abuts against the outer surface of the connecting pipe fitting 6. The connecting pipe fitting 6 is used to connect the two mounting sleeves, and the width of the foot piece 4 can be further adjusted by using connecting pipe fittings 6 of different lengths.

[0026] Specifically, the upper end of the support foot 8 is provided with a rubber pad 801, and the lower end is provided with a first threaded hole 802. One end of the foot body 4 is the rubber pad 801, and the other end is the threaded hole. When the base is placed on a floor that is easily scratched, such as a wooden board, the rubber pad 801 can be set downwards. The first threaded hole 802 facilitates the assembly of accessories such as casters.

[0027] Specifically, the upper surface of the base 1 is provided with several grooves 14, which are arranged in an oblong shape. The grooves 14 on the surface of the base 1 can be threaded through to tighten them.

[0028] Specifically, the base 1 has several second threaded holes 15 on its side. The several second threaded holes 15 on the side of the base 1 can be used to lock the accessories.

[0029] Specifically, a level bubble level 16 is installed inside the base 1. The level bubble level 16 on the upper surface of the base 1 allows customers to easily observe the level of the entire mechanism in real time.

[0030] Specifically, the base 1 is arranged in the shape of a regular hexagon.

[0031] When implementing this utility model, when it is necessary to adjust the left and right positions of the support foot 8, that is, to adjust the distance between the support foot 8 and the center of the base 1, the free end of the first movable handle 9 is loosened so that the free end of the first movable handle 9 no longer touches the surface of the groove 301 of the column 3, but is partially located in the groove 301 to prevent the entire foot body 4 from falling off. The entire foot body 4 is rotated to change the distance between the support foot 8 and the center of the base 1, thereby completing the adjustment of the left and right positions.

[0032] When it is necessary to adjust the height of the support foot 8, loosen the second movable handle 10 so that the free end of the second movable handle 10 is separated from the outer circumference of the support foot 8. Move the support foot 8 vertically up and down in the second mounting sleeve 7 to the desired position, and then tighten the second movable handle 10.

[0033] This utility model is not limited to the above embodiments.
