[0023] As attached Figure 1-7 As shown, this embodiment shows a multi-angle telescopic self-locking support frame, including a tripod base 1 and a tripod rod 2 connected to the bottom of the tripod base 1, and at least two tripod rods 2 are provided. Specifically, in this embodiment, two tripod rods 2 are provided.

[0024] The tripod base 1 is provided with a support platform 3, which 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.

[0025] Among them, a lifting assembly is arranged in the support platform 3, and the lifting assembly includes a knob 4, a screw rod 5, a lifting block 6, a connecting rod 7, a latch 8 and two clamping blocks 9. Specifically, the knob 4 is arranged at the bottom of the support platform 3, one end of the screw rod 5 is connected to the knob 4, and the other end of the screw rod 5 penetrates into the support platform 3 and is rotatably connected to the lifting block 6, and the lifting block 6 is fixed in the support platform 3. The clamping block 9 is located on one side of the screw rod 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 latch 8 is located between the lifting block 6 and the clamping block 9, and the latch 8 is fixed in the support platform 3, and the latch 8 is arranged through the connecting rod 7. The clamping block 9 is lifted out of the support platform 3 or lowered into the support platform 3 under the action of the lifting assembly.

[0026] The clamping block 9 includes a first vertical portion 901, a bent 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, and the clamping blocks 904 of the two clamping blocks 9 are arranged facing each other. Such an arrangement enables the opening between the two clamping blocks 9 to open when the clamping block 9 rises, so as to facilitate the clamping of the photographing device. When the clamping block 9 descends, the opening between the two clamping blocks 9 is reduced to lock the photographing device.

[0027] The upper surface of the support platform 3 is provided with a telescopic opening 10 . The clamping block 9 is lifted out of the support platform 3 or lowered into the support platform 3 from the telescopic opening 10 .

[0028] The working principle of the multi-angle telescopic self-locking support frame of this embodiment is as follows: place the two tripod rods 2 of the support frame on the ground, then turn 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 shooting device between the two clamping blocks 9, then reverse the knob 4 to raise the lifting block 6, and the lifting block 6 drives the clamping block 9 to descend. During the descent process, the two clamping blocks 9 are squeezed by the telescopic opening 10, so that the distance between the two clamping blocks 9 is reduced, and the shooting device is clamped to achieve the purpose of locking the shooting device.

[0029] A limit block 11 is provided below the upper surface of the support platform 3, and a groove 12 is provided on the bottom surface of the limit block 11, and the latch 8 is located in the groove 12. The limit block 11 is in a rectangular parallelepiped shape as a whole, and the groove 12 is provided on the lower surface of the limit block 11. In this embodiment, the groove 12 is provided to limit the position of the stable latch 8 to prevent the connecting rod 7 from shaking during movement.

[0030] Among them, a limiting groove 13 is set in the limiting block 11, and the limiting groove 13 cooperates with the connecting rod 7. Specifically, the limiting groove 13 is located in the middle of the limiting block 11, and the limiting groove 13 divides the limiting block 11 into two parts, left and right. The setting of the limiting groove 13 is also used to limit and stabilize the connecting rod 7 to prevent the connecting rod 7 from shaking during movement.

[0031] Specifically, a threaded hole is provided on the lifting block 6, and the screw rod 5 cooperates with the threaded hole to convert the rotation of the screw rod 5 into the vertical movement of the lifting block 6. A connecting groove 14 is provided on the 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. An insertion rod is provided in the connecting groove 14 to hinge the connecting rod 7 in the connecting groove 14.

[0032] In some embodiments, a buffer pad 15 is provided on the upper surface of the support platform 3. The buffer pad 15 is used to reduce the vibration of the shooting device to protect the shooting device.

[0033] In the above embodiment, the bottom of the support platform 3 is arranged in an arc shape, and the tripod base 1 is provided with an arc groove 20 to match the bottom of the support platform 3 .

[0034] The top of the tripod base 1 is connected to the bottom of the support platform 3 by a screw 16, one end of the screw 16 is screwed into the support platform 3 and the tripod base 1 in turn, and a wrench 19 is provided at the other end of the screw 16. A travel groove 17 is provided in the tripod base 1, a nut 18 is provided in the travel groove 17, and the nut 18 is connected to the screw 16.

[0035] In the above structure, the user can adjust the tightness between the tripod base 1 and the support platform 3 by rotating the wrench 19, which drives the screw rod 16 to rotate. The gap between the tripod base 1 and the support platform 3 can be increased by rotating the wrench 19 to reduce the friction between the tripod base 1 and the support platform 3, and then the angle of the support platform 3 relative to the tripod base 1 can be adjusted. After adjusting the angle, the wrench 19 can be reversed to increase the friction between the tripod base 1 and the support platform 3.

[0036] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
