The prior art discloses a patent with publication number CN207729086U, and this scheme includes that the hoop shell, the shell is hooped under, strap, screw rod and hoop tile, and the hoop shell is hooped under and is adorned admittedly together, and the screw rod is adorned in the cavity that the shell formed under and around soon, and the stiff end of strap is bent and is formed spacing arch and spacing on the bottom surface of the shell is hooped under to, and the free end of strap wears to adorn in the cavity and meshes its characterized in that with the screw rod mutually: the upper hoop shell is provided with a riveting claw hole, the lower hoop shell is provided with a riveting claw, and the upper hoop shell and the lower hoop shell realize riveting by penetrating the riveting claw into the corresponding riveting claw hole; the hoop tile comprises the tile body and the mounting claws, the mounting claws distributed in a cross shape are arranged in the middle of the back face of the tile body, the mounting holes are uniformly distributed on the strap, and the hoop tile is fixedly mounted in the mounting holes by riveting the mounting claws.

The device gradually exposes the defects of the technology along with production and use, and is mainly shown in the following aspects:

first, the existing integrated clamp is limited by the opening and closing size of the opening, and cannot be used for fastening and connecting large grooves.

Second, current split type clamp in assembly process, needs fasten the both ends of clamp simultaneously, and complex operation wastes time and energy.

Third, the connection fastening nature between it and the slot pipe fitting can't be guaranteed to current connecting piece, often appears the phenomenon that the too pine leads to the landing, and the pretightning force between be convenient for control assurance its and the slot pipe fitting not.

In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.

As an optimized scheme, the two fastening plates are respectively provided with fastening holes which are oppositely arranged, and the self-breaking bolt is inserted into the fastening holes.

As an optimized scheme, the fastening holes are oval holes, and the direction of long-distance hole walls of the oval holes is the same as the axial direction of the groove pipe fitting.

As an optimized scheme, the column end of the self-breaking bolt penetrates through the two fastening holes and is in threaded connection with a fastening nut, and a self-breaking groove is coaxially formed in the peripheral wall of the handle end of the self-breaking bolt.

As an optimized scheme, the clamping piece comprises a snap ring fixedly connected to the end part of one of the hoops, and the end part of the other hoop is further fixedly connected with a clamping jaw clamped in the snap ring.

As an optimized scheme, clamping grooves are further formed in the inner walls of the two hoops along with the shape of the hoops.

Compared with the prior art, the utility model has the beneficial effects that:

the two hoops are adopted, one ends of the two hoops are detachably connected through the clamping piece, so that the rapid assembly is convenient to realize, and the other ends of the two hoops are connected through the self-breaking bolt, so that the rapid assembly of the groove pipe fitting is realized;

an assembly bevel opening is formed between the abutting surfaces of the fastening plates, so that the pipe fitting is convenient to mount with a groove pipe fitting, and is convenient and rapid;

through the self-breaking bolt, when the pre-tightening force reaches a certain value, the self-breaking bolt is broken through the self-breaking groove, the pre-tightening force between the hoop and the groove pipe fitting is convenient to grasp, and the operation is convenient;
