[0030] The following is further detailed through specific implementation manners:

[0031] Reference numerals in the accompanying drawings of the specification include: tripod base 1, tripod rod 2, support platform 3, knob 4, lead screw 5, lifting block 6, connecting rod 7, pin 8, clamping block 9, first vertical portion 901, bending portion 902, second vertical portion 903, clamping block 904, telescopic opening 10, limiting block 11, groove 12, limiting groove 13, connecting groove 14, buffer pad 15, screw 16, stroke groove 17, nut 18, wrench 19, arc groove 20.

[0032] As shown in the attached Figure 1-7 figure, this embodiment shows a multi-angle retractable self-locking support frame, including a tripod base 1 and a tripod rod 2 connected below the tripod base 1. At least two tripod rods 2 are provided. Specifically, two tripod rods 2 in this embodiment are provided.

[0033] Among them, a support platform 3 is provided on the tripod base 1, and the support platform 3 is rotatably connected to the tripod base 1. The user can adjust the angle of the shooting device on the support platform 3 relative to the tripod base 1 by rotating the support platform 3.

[0034] Among them, a lifting component is arranged inside the support platform 3. The lifting component includes a knob 4, a lead screw 5, a lifting block 6, a connecting rod 7, a bolt 8 and two clamping blocks 9. Specifically, the knob 4 is arranged at the bottom of the support platform 3. One end of the lead screw 5 is connected to the knob 4, and the other end of the lead screw 5 penetrates into the support platform 3 and is rotatably connected to the lifting block 6. The lifting block 6 is fixed inside the support platform 3. The clamping block 9 is located on one side of the lead screw 5. One end of the connecting rod 7 is connected to the lifting block 6, and the other end of the connecting rod 7 is connected to the two clamping blocks 9. The bolt 8 is located between the lifting block 6 and the clamping block 9. The bolt 8 is fixed inside the support platform 3 and passes through the connecting rod 7. The clamping block 9 rises out of the support platform 3 or descends into the support platform 3 under the action of the lifting component.

[0035] Among them, the clamping block 9 includes a first vertical portion 901, a bending portion 902, a second vertical portion 903 and a clamping block 904 which are connected in sequence. The clamping block 904 is fixed on the first vertical portion 901. The clamping blocks 904 of the two clamping blocks 9 are arranged facing each other. Such a setting makes the opening between the two clamping blocks 9 open when the clamping block 9 rises, facilitating the clamping of the photographing device. When the clamping block 9 descends, the opening between the two clamping blocks 9 shrinks to lock the photographing device.

[0036] Among them, a telescopic opening 10 is arranged on the upper surface of the support platform 3. The clamping block 9 rises out of the support platform 3 or descends into the support platform 3 from the telescopic opening 10.

[0037] The working principle of the multi-angle telescopic self-locking support frame in this embodiment is as follows: Place the two tripod legs 2 of the support frame on the ground, then rotate the knob 4 to lower the lifting block 6. The lifting block 6 drives the clamping block 9 to rise through the connecting rod 7. The clamping block 9 extends out of the support platform 3 through the telescopic opening 10. After extending out of the support platform 3, the user can clamp the photographing device between the two clamping blocks 9. Then reverse the knob 4 to raise the lifting block 6. The lifting block 6 drives the clamping block 9 to descend. During the descending process of the two clamping blocks 9, both are squeezed by the telescopic opening 10, so that the distance between the two clamping blocks 9 decreases, clamping the photographing device to achieve the purpose of locking the photographing device.

[0038] Among them, a limiting block 11 is arranged below the upper surface of the support platform 3. A groove 12 is arranged on the bottom surface of the limiting block 11. The bolt 8 is located in the groove 12. The limiting block 11 is in an overall cuboid shape. The groove 12 is arranged on the lower surface of the limiting block 11. In this embodiment, the position of the stable bolt 8 is limited by arranging the groove 12 to prevent the connecting rod 7 from shaking during movement.

[0039] Among them, a limiting groove 13 is arranged inside the limiting block 11. The limiting groove 13 cooperates with the connecting rod 7. Specifically, the limiting groove 13 is located at the middle position of the limiting block 11. The limiting groove 13 divides the limiting block 11 into left and right parts. The arrangement of the limiting groove 13 is also used to limit the stable connecting rod 7 to prevent the connecting rod 7 from shaking during movement.

[0040] Specifically, a threaded hole is formed in the lifting block 6, and the lead screw 5 is matched with the threaded hole to convert the rotation of the lead screw 5 into the vertical movement of the lifting block 6. Wherein, a connecting groove 14 is arranged on one side of the lifting block 6 close to the clamping block 9, and the connecting rod 7 is connected to the lifting block 6 in the connecting groove 14. A plug rod is arranged in the connecting groove 14, and the connecting rod 7 is hinged in the connecting groove 14.

[0041] In some embodiments, a buffer pad 15 is arranged on the upper surface of the support table 3. The buffer pad 15 is used to reduce the vibration of the shooting device to protect the shooting device.

[0042] In the above embodiment, the bottom of the support table 3 is set in an arc shape, and an arc groove 20 is arranged on the tripod base 1 to be adapted to the bottom of the support table 3.

[0043] Wherein, the top of the tripod base 1 and the bottom of the support table 3 are connected by a screw rod 16. One end of the screw rod 16 is screwed into the support table 3 and the tripod base 1 in sequence, and a wrench 19 is arranged at the other end of the screw rod 16. A travel groove 17 is arranged in the tripod base 1, and a nut 18 is arranged in the travel groove 17. The nut 18 is connected to the screw rod 16.

[0044] In the above structure, the user can rotate the wrench 19, and the wrench 19 drives the screw rod 16 to rotate to adjust the tightness between the tripod base 1 and the support table 3. By rotating the wrench 19, the gap between the tripod base 1 and the support table 3 can be increased to reduce the friction between the tripod base 1 and the support table 3, and then the angle of the support table 3 relative to the tripod base 1 can be adjusted. After adjusting the angle, the wrench 19 is reversed to increase the friction between the tripod base 1 and the support table 3.

[0045] The above are only the embodiments of the present invention. Common general knowledge of specific structures and characteristics in the solution is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners in the specification can be used to interpret the content of the claims.
