Part of the surface of the dial wheel 111 is exposed in a gap (not shown in the figure) provided on the side of the head shaft 11, so the user's fingers can rotate the dial wheel 111 through the gap; the camera connector 113 is in this embodiment 1/4 thread, one end of which is connected to the center of one side of the dial wheel 111 and is integrally formed with the dial wheel 111, and the other end passes through the end surface of the head rod body 11 for fixing with the 1/4 nut on the camera device; The positioning member 112 is formed extending upward from one end of the head shaft 11. In this embodiment, it includes two limiting members 112 symmetrically arranged on both sides of one end of the head shaft 11. The two limiting members 112 are of flat structure and The end is inclined outwards, and the camera is held by the cooperation of the two stoppers 112 to prevent it from rotating with the rotation of the dial 113. The other end of the first section of the rod body 11 is formed with an inclined surface (not marked) that is at an angle of 45° with the axial direction of the first section of the rod body 11. The inclined surface is provided with a mounting hole 114 and two clamping grooves 115, and the mounting hole 114 is round. The distance between the two grooves 115 and the geometric center of the inclined surface is the same, and the angle between the lines connecting the two grooves 115 and the geometric center of the inclined surface is 180°, that is, two The two card slots 115 are on the same straight line with the geometric center of the inclined surface.

As shown in FIGS. 2 to 6, the middle section rod body 12 includes two inclined surfaces (not marked) at an angle of 45° to the axial direction of the middle section rod body 11, and the planes on which the two inclined surfaces are located are perpendicular to each other. In this embodiment, the middle pole 12 has an elliptical column shape, and includes a switch 121, a buckle 123 and a pole connector 122. The switch 121 in this embodiment is vertically arranged in the axial direction of the middle rod body 12 and partially exposed on the surface of the middle rod body 12 for the user to press. The switch 121 includes a wedge portion 121a that abuts against the buckle 123, and another part of the switch 121 A switch spring 125 is installed at one end, and the switch spring 125 is used to restore the switch 121 to the state when the switch 121 is not pressed; 123 includes a clamping end 123a and an abutting end 123b. The clamping end 123a can pass through a through hole (not marked) on an inclined surface of one end of the middle section of the rod body 12 and then be clamped in a groove on the inclined surface of the first section of the rod body 11. In 115, the abutting end 123b is in contact with the wedge portion 121a of the switch, and the diameter of the holding end 123a is smaller than the diameter of the abutting end 123b. The holding end 123a is sleeved with a buckle spring 124. The force is less than the elastic restoring force of the switch spring 125; in this embodiment, the rod body connector 122 is installed at the geometric center of the inclined surface of the middle section rod body 12, and includes a connecting rod (not marked) and a fixing part (not marked), specifically, The connecting rod is a 1/4 threaded end connected to the geometric center of the inclined surface of the middle section rod body 12 and integrally formed with the middle section rod body 12. The fixing part is a 1/4 nut, and the diameter of the connecting rod is slightly smaller than the mounting hole on the first section rod body 11. 114. The diameter of the fixing part is larger than the mounting hole. Therefore, after the connecting rod is passed through the mounting hole on the first section of the rod body 11, the fixing part is rotated and fixed on the connecting rod, thereby connecting the first section of the rod body 11 and the middle section of the rod body 12 to the Together. In this embodiment, the connection manner of the middle section rod body 12 and the tail section body 13 is basically the same as the connection manner of the middle section rod body 12 and the first section rod body 11.

As shown in FIGS. 3 and 4, the tail section rod 13 is also in the shape of an elliptical cylinder, and one end is provided with an inclined surface that is 45° with the axial direction of the tail section rod 13. The tail section rod body 13 is roughly the same as the first section rod body 11, but the difference is: the tail section rod body 12 does not have a dial, a camera connection piece, and a limit piece, but an accessory device connection is provided at the center of the opposite end of the inclined surface. In this embodiment, the accessory device connecting piece 131 is a 1/4 threaded hole.

As shown in Figures 1, 5, and 6, when the switch 121 is not pressed, the clamping end 123a of the buckle 123 passes through the inclined surface of the middle section of the rod body 12 and extends into one of the inclined surfaces of the first section of the rod body 11. At this time, the first-stage rod 11 cannot rotate relative to the middle-stage rod 12.

As shown in Figures 7, 8, and 9, when the switch 121 is pressed, the switch 121 and its wedge portion 121a move to the right (radial direction), so that the wedge portion 121a is out of contact with the abutting end 123b of the buckle 123. Under the action of the buckle spring 124, the buckle 123 moves downward (axially) as a whole, so that the clamping end 123a of the buckle 123 is withdrawn from the groove 115. At this time, the first section rod 11 can rotate relative to the middle section rod 12 . When the first section of the rod body 11 rotates 180° with respect to the middle section of the rod body 12 with the rod body connector 122 as the central axis, the first section of the rod body 11 and the middle section of the rod body 12 are perpendicular to each other. The through hole on the inclined surface of the middle section rod body 12 extends into another slot 115 of the first section rod body 11 so as to maintain the first section rod body 11 and the middle section rod body 12 in a mutually perpendicular positional relationship.

The cross section of the rod body (including the first section rod body 11, the middle section rod body 12 and the tail section rod body 13) of the folding rod of the present invention can also be circular or regular N-sided (where N is greater than or equal to 4), and at this time, the two clamping slots 115 The angles between the connecting lines with the center of the inclined surface can be set to 90 degrees. At this time, the adjacent rods are rotated by 90 degrees, and the adjacent rods can also be perpendicular to each other and the joints of the adjacent rods can be smoothly connected.

The rod body connector of the folding rod of the present invention may also be composed of a connecting rod and two fixing parts. One fixing part fixes one rod body and one end of the connecting rod together, and the other fixing part fixes the adjacent rod body of the rod body and the connecting rod together. The other ends are fixed together.

The positions of the fixed connection parts in the present invention can be exchanged with each other, and corresponding functions can also be realized.
