[0040] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a panoramic holder, including clamping body 1, the bottom of clamping body 1 is provided with recess 11 that is overall cylindrical, the recess 11 is installed with base 2 respectively in rotatable mode, base 2 is overall discoid, and the middle portion of base 2 protrudes outward and forms circular table 21 that is rotatable with recess 11;

[0041] The top center of the clamping body 1 is provided with a connecting hole 15 communicated with the groove 11, the top of the circular table 21 extends into the connecting hole 15, and the top of the circular table 21 is provided with a threaded hole B211 penetrating in the top-down direction, a connecting piece 5 is arranged in the connecting hole 15 and is screwed with the threaded hole B211 to movably connect the clamping body 1 and the bottom disc 2, the connecting piece 5 is not locked, so that the clamping body 1 can rotate relative to the bottom disc 2, the outer surface of the bottom disc 2 is provided with a scale line, and the rotation angle of the clamping body 1 can be known through the scale line, and the connecting piece 5 is hollow, and a bolt is arranged in the connecting piece 5, so that the utility model is installed and used.

[0042] Please refer to Figure 4 and Figure 5 , the groove 11 is movably provided with a locking arm 3, the locking arm 3 is located at the edge of the bottom disc 2, and the side of the clamping body 1 is screw-connected with a rotating and pushing piece 4 for pushing the locking arm 3 to rotate and abut against the circular table 21, so that the clamping body 1 is locked;

[0043] Please refer to Figures 4 to 6 , the groove 11 is provided with a mounting hole 13, the locking arm 3 comprises a rotating shaft 31 movably matched with the mounting hole 13, the rotating shaft 31 is inserted into the mounting hole 13, and the locking arm 3 further comprises a driving part 32, one end of the driving part 32 is integrally formed with the rotating shaft 31, the other end of the driving part 32 extends to the front of the rotating and pushing piece 4, and the end of the driving part 32 close to the rotating shaft 31 protrudes to form a protrusion 33 towards the direction of the circular table 21, the protrusion 33 is used for improving the friction between the locking arm 3 and the circular table 21, and further improving the locking effect on the clamping body 1;

[0044] Please refer to Figure 2 and Figure 5 , the side of the clamping body 1 is provided with a threaded hole A14 communicated with the groove 11, the rotating and pushing piece 4 comprises a screw rod A41 screw-connected in the threaded hole A14, one end of the screw rod A41 extends into the groove 11, the other end of the screw rod A41 extends out of the clamping body 1, and the end of the screw rod A41 extending out of the clamping body 1 is fixedly connected with a knob A42, when the knob A42 is screwed inwards, the screw rod A41 can be driven to move along the length direction of the threaded hole A14, the locking arm 3 is further driven to rotate around the rotating shaft 31 as the rotation center, the protrusion 33 is driven to abut against the surface of the circular table 21 to lock the clamping body 1;

[0045] Since the locking arm 3 is a type II lever, the pivot 31 is the fulcrum (P) of the locking arm 3, the point where the protrusion 33 abuts against the frustum 21 is the resistance point (R), the protrusion 33 and the pivot 31 form the resistance arm of the lever structure, the contact point where the rotary pusher 4 pushes the locking arm 3 to rotate is the force application point (F), and the force-receiving end of the locking arm 3 that rotates due to the pusher 4 and the pivot 31 form the power arm of the lever structure, wherein the power arm is greater than the resistance arm. When locking the clamping body 1, when the rotary pusher 4 is turned with very little force to push the locking arm 3 to rotate, the protrusion 33 can generate a large force on the frustum 21, thus achieving a better locking effect and greatly improving the user experience.

[0046] Please see Figure 7 The outer surface of one end of the screw A41 that extends into the groove 11 is provided with a slot 43, and a retaining ring 44 is fitted in the slot 43. The retaining ring 44 is used to limit the movement of the screw A41 when the knob A42 is turned outward, so as to prevent the screw pusher 4 from disengaging from the threaded hole A14 and being lost.

[0047] Secondly, when the knob A42 can no longer be turned outward under the action of the retaining ring 44, it can serve as a reminder that the locking of the clamping body 1 has been released. At this time, the clamping body 1 can be rotated horizontally relative to the low base 2 to adjust the usage angle.

[0048] Please see Figures 1 to 3 The clamping body 1 includes a housing 16 with the groove 11. A fixed clamp 163 is integrally formed on the top of the housing 16. A notch 161 is formed on the side of the housing 16 away from the fixed clamp 163. A movable clamp 6 is installed in the notch 161. The movable clamp 6 is used to cooperate with the fixed clamp 163 to clamp the camera quick-release plate.

[0049] Please see Figure 2 , Figure 3 , Figure 4 and Figure 8 The side wall of the notch 161 is provided with a receiving cavity 162. The movable clamp 6 is integrally formed with a positioning arm 7 that is inserted and cooperates with the receiving cavity 162 on the side facing the receiving cavity 162. The positioning arm 7 is generally "C" shaped. A spring 8 is installed in the positioning arm 7. The spring 8 is used to generate an outward force on the movable clamp 6.

[0050] Please see Figure 3 , Figure 8 and Figure 10A screw B9 is fixedly connected in the notch 161. A through hole 61 is provided on the movable chuck 6. The screw B9 extends outward through the through hole 61, and a knob B10 is threadedly connected to the extended end of the screw B9.

[0051] When the knob B10 is turned outward, the knob B10 moves outward along the screw B9. At this time, the movable clamp 6 slides outward under the force generated by the deformation of the spring 8, and the movable clamp 6 moves away from the fixed clamp 163. At this time, the camera can be installed or removed.

[0052] When the knob B10 is turned inward, the knob B10 pushes the movable clamp 6 to move closer to the fixed clamp 163, thereby fixing the camera. A planar thrust bearing 12 can be installed between the knob B10 and the movable clamp 6 to bear axial force, making the operation of the knob B10 smoother.

[0053] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
