The inner diameter of the fixing portion 2511 is larger than the outer diameter of the second rod 23, so that the second rod 23 can movably penetrate through the fixing portion 2511. In the present embodiment, the connection between the fixing portion 2511 and the first rod 21 is a glue bond. It is understood that the fixing portion 2511 and the first rod 21 may be connected by mechanical connection methods such as interference fit, welding, screwing, and screwing. The flange 2513 is formed at an end of the fixing portion 2511 away from the first positioning portion 211, and protrudes out of the first rod 21 along a radial direction of the fixing portion 2511, and abuts against an end of the first rod 21.
The slider 253 has a substantially cylindrical shape and is fixedly disposed at one end of the second rod 23 inserted into the first rod 21. The slider 253 includes a receiving portion 2531 and a receiving portion 2533 formed on the receiving portion 2531. The sleeve portion 2531 is substantially cylindrical with a bottom wall, and is fixedly sleeved on the second rod 23. When the second rod 23 is in the maximum extending state relative to the first rod 21, the engaging portion 2531 abuts against the fixing portion 2511 to prevent the second rod 23 from being released from the first rod 21. The receiving portion 2533 is formed at an end of the sleeve portion 2531 away from the second rod 23, and has a receiving cavity 2535 formed on an outer peripheral wall thereof, and a guiding portion 2536 is formed on a side wall of the receiving cavity 2535.

In the present embodiment, the guide portion 2536 is a guide groove recessed in a sidewall of the housing cavity 2535, and extends substantially along an axial direction of the housing cavity 2535. The guide portion 2536 is used for guiding the moving direction of the positioning member 257 in the receiving cavity 2535.
In the present embodiment, the elastic member 255 is a coil spring, and is disposed in the accommodating cavity 2535.
The positioning member 257 is partially received in the receiving cavity 2535 and can move along the axial direction of the receiving cavity 2535 to protrude out of the receiving cavity 2535 or retract into the receiving cavity 2535. The positioning member 257 is selectively clamped or separated from the two positioning portions 210 to position the mounting position of the second rod 23 relative to the first rod 21. The positioning member 257 includes a stopper portion 2571 and an engaging portion 2573 formed on the stopper portion 2571. The position-limiting portion 2571 is connected to the elastic member 255, such that two ends of the elastic member 255 respectively abut against the positioning member 257 and the bottom wall of the accommodating cavity 2535. The maximum outer diameter of the stopper portion 2571 is larger than the inner diameter of the positioning portion 210, and an engagement portion 2572 is formed on the outer peripheral wall thereof. In the present embodiment, the engaging portion 2572 is a guiding protrusion formed by protruding the outer peripheral wall of the limiting portion 2571, and is disposed corresponding to the guiding portion 2536 of the sliding member 253, and can slide along the extending direction of the guiding portion 2536 to guide the moving direction of the positioning member 257 in the accommodating cavity 2535.
The engaging portion 2573 protrudes from an end of the stopper portion 2571 away from the elastic member 255, and has an outer diameter smaller than the inner diameter of the positioning portion 210 and larger than the width dimension of the guide groove 220. When the positioning element is pushed by the elastic force of the elastic element 255 to make the engaging portion 2573 protrude into the positioning portion 210, the limiting portion 2571 abuts against the inner wall of the first rod 21 to prevent the positioning element 257 from coming off from the positioning portion 210. When the engaging portion 2573 is pressed by an external force, it is disengaged from the positioning portion 210. When the supporting rod 20 is in a stable expanded state or a stable contracted state, the engaging portion 2573 protrudes into the corresponding first positioning portion 211 or the second positioning portion 213 to be clamped with the corresponding first positioning portion 211 or the second positioning portion 213, so as to position the installation position of the second rod 23 relative to the first rod 21.
The pressing member 259 is connected to the engaging portion 2573 and protrudes out of the first rod 21, and is used for providing a portion for a user to press and operate the supporting rod 20. The pressing piece 259 includes a pressing portion 2591 and a connecting portion 2593 formed on the pressing portion 2591.
The pressing portion 2591 has a substantially flat cylindrical shape and a diameter larger than the diameter of the positioning portion 210. The connecting portion 2593 protrudes from the pressing portion 2591 toward one side of the first rod 21 and extends toward the first rod 21. The connecting portion 2593 has an outer diameter smaller than the width of the guide groove 220, and is inserted into the positioning portion 210 or the guide groove 220 to be fixedly connected to the engaging portion 2573 of the positioning member 257. When the pressing portion 2591 is pressed by an external force, the connecting portion 2593 pushes the positioning member 257 toward the first rod 21, so that the engaging portion 2573 is separated from the positioning portion 210. At this time, the connection portion 2593 passes through the positioning portion 210, can slide into the guide groove 220 from the positioning portion 210, and can slide in the longitudinal direction of the guide groove 220. After the pressing force is removed, if the connecting portion 2593 drives the positioning member 257 to slide to one of the positioning portions 210 along the guiding groove 220, the engaging portion 2573 is pushed down by the elastic member 255 and protrudes into the positioning portion 210 again due to the loss of the blocking effect of the inner wall of the first rod 21.
Referring to fig. 1 again, the first mounting seat 27 is installed at one end of the first positioning portion 211 of the first rod 21, and is used for installing the first supporting arm 40. Specifically, in the illustrated embodiment, the first mounting seat 27 includes a seat body 271 fixedly mounted on the first rod 21 and a connecting member 273 rotatably mounted on the seat body 271. In this embodiment, the number of the connectors 273 is two, and the two connectors 273 are respectively disposed at both ends of the base body 271. Under the driving of external force, the connecting member 273 can rotate to a predetermined angle relative to the seat body 271, and stop rotating after being clamped with the seat body 271.
The second mounting seat 28 is disposed at an end of the second rod 23 away from the first rod 21 and is used for connecting the second supporting arm 50. Specifically, in the illustrated embodiment, the structure of the second mounting seat 28 is substantially the same as that of the first mounting seat 27, and also includes a seat body 281 and a connecting member 283 connected to the seat body 281, which are not described in detail herein for brevity. The second mount 28 differs from the first mount 27 in that: the seat 281 of the second mounting seat 28 is rotatably sleeved on the second rod 23. It is understood that the number of the coupling members 283 of the second mounting seat 28 and the number of the coupling members 273 of the first mounting seat 27 may be one or more.
The fastening member 29 is mounted on the seat 281 of the second mounting seat 28, and is used for fixing the second mounting seat 28 on the second rod 23. One end of the fastener 29 penetrates through the seat 281 and abuts against the second rod 23, so that the second mounting seat 28 can be relatively and fixedly mounted on the second rod 23.
In the present embodiment, the number of the first support arm 40 and the second support arm 50 is two. The two first supporting arms 40 are respectively installed on the two connecting parts 273 of the first mounting seat 27, and the two second supporting arms 50 are respectively installed on the two connecting parts 283 of the second mounting seat 28. Under the driving of external force, the first supporting arm 40 and the second supporting arm 50 can both rotate to a preset supporting angle relative to the supporting rod 20 and are fixed. Specifically, in the illustrated embodiment, the two first support arms 40 are unfolded into a "V" shaped support configuration and are generally perpendicular to the support bar 20. Likewise, the two second support arms 50 are unfolded to assume a "V" shaped support state and are substantially perpendicular to the support bar 20. It is understood that the number of the first support arms 40 and the second support arms 50 can be one or more, and even when the number of the first support arms 40 satisfies the supporting requirement of the supporting stand 100, the second support arms 50 and the second mounting seats 28 can be omitted.
In this embodiment, the number of the hanging members 60 is two, and each hanging member 60 is installed at an end of one of the second supporting arms 50 far away from the second installation seat 28. The hanging member 60 is used for mounting and supporting the cradle head.
When assembling the supporting stand 100 of the present embodiment, first, the elastic element 255 and the positioning element 257 are sequentially disposed in the accommodating portion 2533, and then the sliding element 253 is fixedly disposed on the second rod 23, and the fixing element 251 is sleeved on the second rod 23. Next, the second rod 23 is inserted into the first rod 21, so that the positioning element 257 corresponds to the positioning portion 210, and then the fixing member 251 is fixedly connected to the first rod 21, so that the flange portion 2513 of the fixing member 251 abuts against the end portion of the first rod 21. Then, the second rod 23 is adjusted to make the positioning member 257 protrude into the first positioning portion 211 or the second positioning portion 213, and the connecting portion 2593 of the pressing member 259 passes through the first positioning portion 211 or the second positioning portion 213 and is connected to the engaging portion 2573. Third, the first mounting seat 27 is installed on the first rod 21, the second mounting seat 28 is installed on the second rod 23, and the first supporting arm 40 and the second supporting arm 50 are respectively connected to the first mounting seat 27 and the second mounting seat 28. Finally, the second mounting seat 28 is fixed to the second rod 23 by the fastening member 29, and the hanging member 60 is mounted on the second supporting arm 50.
In the non-use state, the second rod 23 is completely accommodated in the first rod 21, and the engaging portion 2573 of the positioning member 257 protrudes into the second positioning portion 213, so that the supporting rod 20 is in a stable contracted state; the first support arm 40 and the second support arm 50 are disposed adjacent to and stacked on the support rod 20 and are disposed substantially parallel to the support rod 20.
When the supporting frame 100 of the present invention is used, first, an external force is applied to the pressing member 259, so that the pressing portion 2591 of the pressing member 259 pushes the positioning member 257 toward the inside of the first rod 21, and the positioning member 257 is separated from the second positioning portion 213. Then, the second rod 23 is pulled to be away from the first rod 21, the pressing member 259 slides along the length direction of the guiding groove 220 until the pressing member 259 moves to the first positioning portion 211, the external force is removed, and the engaging portion 2573 protrudes into the first positioning portion 211 under the pushing of the elastic member 255 due to the loss of the blocking effect of the inner wall of the first rod 21, so that the second rod 23 and the first rod 21 are relatively fixed. Then, an external force is applied to the first supporting arms 40 to rotate relative to the supporting rod 20 and away from the supporting rod 20 until the two first supporting arms 40 are "V" shaped and the axes of the first supporting arms 40 are substantially perpendicular to the supporting rod 20.
