[0026] At the same time, a first disassembly protrusion 118 is provided on the outer side wall of the first protective shell 104 away from the first fastening plate 107, and a second disassembly protrusion 119 is provided on the outer side wall of the second protective shell 105 away from the second fastening plate 109. The arrangement of the first disassembly protrusion 118 and the second disassembly protrusion 119 makes it more convenient to disassemble and assemble the first protective shell 104 and the second protective shell 105.

[0027] In addition, an anti-slip rubber layer 120 is provided inside the first card slot 112 and the second card slot 113. Through the provision of the anti-slip rubber layer 120, the first protective shell 104 and the second protective shell 105 are more firmly connected to the corresponding first card slot 112 and the second card slot 113.

[0028] When using the grooved pipe clamp assembly of the present invention, the first clamp 101 and the second clamp 102 are quickly assembled by the arrangement of the clamp ring 106 and the clamping claw 108. The first clamp 101 and the second clamp 102 are fastened by the arrangement of the self-breaking bolt 103. When the pre-tightening force reaches a certain value, the self-breaking bolt 103 breaks through the self-breaking groove, which makes it easy to grasp the pre-tightening force between the clamp and the grooved pipe, and is easy to operate. At the same time, when the self-breaking bolt 103 is used to realize After the first clamp 101 and the second clamp 102 are tightened, the first protective shell 104 is clamped in the first slot 112, and the second protective shell 105 is clamped in the second slot 113. The first protective shell 104 and the second protective shell 105 are used to protect the self-breaking bolt 103 to prevent the external environment from corroding the connection between the self-breaking bolt 103 and the first fastening plate 107 and the second fastening plate 109, thereby avoiding subsequent impact on the disassembly and assembly of the clamp assembly.
