[0006] Preferably, a groove matching the flip plate is formed at one end of the positioning hole, so that the flip plate can be conveniently embedded in the groove for placement when flipping.

[0007] Preferably, the upper surfaces of both ends of the second support ring are provided with placement grooves, and the flip clamping parts are located in the placement grooves, so that the flip clamping parts can be stored and placed when not in use.

[0008] Preferably, the first support ring and the second support ring are both semicircular, and an opening for the clamping assembly to move is provided at the middle position of the first support ring and the second support ring, so as to reserve space for adjusting the spacing between the clamping assemblies at both ends.

[0009] Preferably, an adjustment seat is provided on the outer wall of the first support ring and the second support ring, and the first support ring and the second support ring are respectively installed with a first clamping assembly and a second clamping assembly through the adjustment seat.

[0010] Preferably, the first clamping assembly and the second clamping assembly include a screw, one end of the screw is provided with a chuck, an outer wall of the chuck is provided with a clamping opening, and the other end of the screw is provided with a handle.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model drives the flip plate to rotate by the rotating shaft, so that the card block is embedded in the card slot from the positioning hole, so that the first support ring and the second support ring are firmly combined and fixed together. When the card block is inserted into the card slot, the flip plate will flip and embed into the groove. In the separated state, the flip plate will be stored in the placement slot. When disassembling, it is only necessary to rotate the flip plate backward to disengage the card block from the card slot, and then pull the insert block out of the slot.

[0013] Through the above-mentioned connection structure, the two support rings can be combined in an inserted combination manner. On this basis, the insert is secondary restricted by flipping and snapping, so that the two support rings are assembled more stably and firmly, and are easy to operate and use. The connection structure is small in size, and is more convenient for users to carry and use. BRIEF DESCRIPTION OF THE DRAWINGS
