[0002] In daily production, we often encounter situations where two rods are connected and fixed vertically. Taking photovoltaic installation as an example, a photovoltaic panel fixing device is provided in the related art, such as Figure 6 , Figure 7 As shown, when the photovoltaic panel 100 needs to be installed and fixed on the inclined beam square tube 200, the purlin 300 is generally used as an intermediary for connecting the photovoltaic panel 100 and the inclined beam square tube 200. At this time, the purlin 300 and the inclined beam square tube 200 need to be vertically connected.

[0003] Specifically, a support structure is first driven into the installation position, and at least two inclined square tubes 200 are fixedly arranged on the support structure in a horizontal and longitudinal interval, that is, the fixed support structure and the inclined square tubes 200 are used as the support basis of the photovoltaic panel 100; then the purlin 300 with multiple connection holes is longitudinally overlapped between the two inclined square tubes 200, and an "L"-shaped adapter 400 is arranged at the connecting position of the purlin 300 and the inclined square tube 200; the "L"-shaped adapter 400 is provided with two circular holes on the side close to the inclined square tube 200, and the side structure of the "L"-shaped adapter 400 is connected to the inclined square tube 200 by using a "U"-shaped bolt 500, and the "L"-shaped adapter 400 is also provided with two circular holes on the side close to the purlin 300, and the side structure of the "L"-shaped adapter 400 is connected to the purlin 300 by using two sets of straight bolts 600.

[0004] When the above scheme is adopted for photovoltaic installation, since the positions of the two inclined beam square tubes 200 are fixed, after the "L"-shaped adapter 400 is used in conjunction with two bolts to connect the joint position of one purlin 300 and the inclined beam square tube 200, at the joint position of another purlin 300 and the inclined beam square tube 200, the two circular holes on the "L"-shaped adapter 400 and the connecting holes on the purlin 300 are easily misaligned, resulting in the "L"-shaped adapter 400 and the purlin 300 here being unable to be connected normally.
