Still install fastener 7 on first latch segment 562 and the second latch segment 563, fastener 7 is including the fastening bolt (not shown in the figure) that runs through first latch segment 562, second latch segment 563 and a set of two connecting rods 55, and fastening bolt and first latch segment 562 are fixed connection, and fastening bolt and second latch segment 563, a set of two connecting rods 55 are rotation connection. The fastening bolt on the side, far away from the first locking block 562, of the second locking block 563 is slidably sleeved with a supporting block 71, and the fastening bolt on the side, far away from the second locking block 563, of the supporting block 71 is screwed with a fastening nut 72 for pushing the supporting block 71 to tightly support the second locking block 563.

The implementation principle of the embodiment is as follows:

when it is desired to use the present telescopic bracket, the telescopic member 1 is first mounted on the tripod 5. At this time, the clamping block 67 is placed in the second through hole 63, and pushes the bottom tube 11, the bottom tube 11 pushes the clamping ring 69, and the clamping ring 69 compresses the clamping spring 68 to deform. Then, the bottom tube 11 is rotated to clamp the clamping block 67 into the sinking groove 64, and after the bottom tube 11 is released, the clamping spring 68 pushes the clamping ring 69, and the bottom tube 11 is pushed by the clamping ring 69, so that the sinking groove 64 and the clamping block 67 are tightly abutted to complete the fastening and installation of the telescopic member 1.

The tripod 5 is adjusted according to the in-service use demand after the installation of extensible member 1 is accomplished, at this moment, only need rotate support column 53, and support column 53 rotates the in-process, drives through connecting rod 55 and slides cover 56 and slide along bottom tube 11. When the adjustment of the tripod 5 is completed, the support column 53 needs to be fixed. At this time, only the fastening nut 72 needs to be screwed, and the fastening nut 72 drives the abutting block 71 to abut against the second locking block 563 and pushes the second locking block 563 to approach the first locking block 562. The first locking block 562 and the second locking block 563 can drive the locking sleeve 561 to abut against the bottom tube 11, so that the position of the sliding sleeve 56 is fixed, and correspondingly, the position of the supporting column 53 is also relatively fixed when the position of the sliding sleeve 56 is fixed. In this process, since the fastening bolt is fixedly connected to the first locking block 562, the fastening bolt is not driven to rotate when the fastening nut 72 is screwed, so that the fastening degree is insufficient. And the connecting rod 55 can connect the support column 53 and the sliding sleeve 56, thereby supporting the support column 53 through the peripheral sidewall of the bottom pipe 11.

Then, according to the actual use requirements, telescopic member 1 is pulled, and the length of telescopic member 1 is adjusted through the relative sliding between connecting pipes 12. Then, the connecting pipe 12 is rotated, and the first segment 121 and the second segment 122 with non-coincident circle centers respectively abut against the first locking piece 211 and the second locking piece 212 in the rotating process and are finally in interference fit, so that the positioning between two adjacent connecting pipes 12 or between the connecting pipe 12 and the bottom pipe 11 is completed.

After the telescopic bracket is used, when the telescopic bracket needs to be folded, the connecting pipe 12 only needs to be rotated reversely, so that the first duct piece 121 and the first locking piece 211 are separated from the abutting state, the second duct piece 122 and the second locking piece 212 are separated from the abutting state, and the telescopic piece 1 can be folded by pushing the connecting pipe 12. The fastener 7 is then loosened and the support 53 is rotated in the opposite direction so that the support 53 snaps into the catch 565, thereby substantially reducing the space occupied by the tripod 5.

In this process, the locking sleeve 561 is not easily separated from the connecting tube 12 or the bottom tube 11 by the engagement of the locking block 23 and the locking hole 24, and the locking block 23 is triangular in cross section to facilitate the installation of the locking sleeve 561. And because the whole locking sleeve 561 is located in the connecting pipe 12 or the bottom pipe 11, when the connecting pipe 12 rotates, the locking sleeve 561 is pushed to abut against the inner side wall of the connecting pipe 12 or the bottom pipe 11, thereby improving the positioning stability of the whole telescopic member 1. The first blocking member 31, namely the first blocking ring 311 and the second blocking ring 312, which are additionally provided, can form a blocking pair for the connecting pipe 12, thereby reducing the possibility that the connecting pipe 12 is separated from the adjacent connecting pipe 12 or the end of the bottom pipe 11 away from the tripod 5. By providing the second blocking member 33, the third blocking ring 332 can reduce the possibility that the connecting pipe 12 will be pulled out from the end of the adjacent connecting pipe 12 close to the tripod 5.

Example 2

As shown in fig. 1 and 7, the embodiment 2 is different from the embodiment 1 in that the connecting member 6 includes a connecting bolt 610 fixedly mounted on a side wall of the mounting block 51 near the bottom pipe 11, a block 61 is fixedly mounted in one end of the bottom pipe 11 near the mounting block 51, a bolt hole 611 coaxial with the block 61 is formed in the block 61, and the bolt hole 611 is in threaded connection with the connecting bolt 610.

The implementation principle of the embodiment is as follows:

the present embodiment is different from embodiment 1 in that the coupling member 6 is implemented in such a manner that the bottom pipe 11 can be easily and stably coupled to the tripod 5 through the coupling bolt 610 and the bolt hole 611.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
