The auxiliary member may be a scale mark or other positioning mark, by which the inner connecting block 3 can be easily and conveniently fed into the connecting hole 11 at a position corresponding to the through hole 22, and particularly, the advantages thereof are more apparent when mass-assembling.
And C: one end of the connecting member 4 is sequentially inserted through the through hole 22 of the outer connecting block 2 and the connecting hole 11 to be coupled with the mounting hole 32 of the inner connecting block 3, so that the hollow circular tube 1 and the outer connecting block 2 are assembled together.
The assembling tool 7 is cylindrical, and the outer diameter of the assembling tool is slightly smaller than the inner diameter of the hollow circular tube 1, so that the assembling tool 7 can conveniently enter and exit the hollow circular tube 1. The assembling tool 7 has an engaging surface 71 at one end which matches the bottom flat surface 34 of the inner joint block 3 and an abutting surface 72 which matches the side surface 35 of the inner joint block 3, that is, the engaging surface 71 is actually a semi-cylindrical flat surface formed by removing a section of a cylinder from one end of the assembling tool 7 substantially along the diameter direction thereof.
In use, the inner joint block 3 is placed on the joint face 71 of the assembling tool 7 with the side face 35 of the inner joint block 3 abutting against the abutting face 72 of the assembling tool 7. The assembly tool 7 is used only as a conveying tool to feed the internal connection block 3 into the hollow circular tube 1 for installation, and after the internal connection block 3 is installed, the assembly tool 7 can be taken out of the hollow circular tube 1 and can continue to convey the next internal connection block 3. Although the assembling tool 7 is separated from the internal connection block 3, the assembling tool 7 may be connected to the hollow circular tube 1 by the connecting member C after the internal connection block 3 is positioned and installed, so that the assembling tool 7 may be used as a handle for the user to operate the whole connection device.
Of course, the assembling tool 7 can also be integrated with the inner connecting block 3, and when the inner connecting block 3 is fixed inside the hollow circular tube 1, the assembling tool 7 is also fixed inside the hollow circular tube 1, as shown in fig. 9 and 10, for example, in this case, the assembling tool 7 can be used as a handle after the connecting device is connected, so that the user can conveniently operate the whole connecting device.
The assembly tool 7 can be obtained from a round tube by simple machining.
