Optionally, the both ends cover of connecting rod is equipped with splint, splint fixed connection is on the body, each the equal threaded connection in both ends that the connecting rod stretches out splint has the nut.

Through adopting above-mentioned technical scheme, splint set up in the welding department both sides and with body fixed connection, link together with the connecting rod to play fixed and the effect of gaining in strength to the connecting rod. When the clamping plate needs to be fastened, the nuts at the two ends of the connecting rod are rotated, so that the two nuts are respectively close to the side walls of the clamping plate, the nuts are kept still, and the connecting rod is rotated. The clamping plates are fixed on the pipe body and are kept still, and the two clamping plates are continuously clamped by screwing the threads of the connecting rod and the nut, so that the connecting stability of the connecting rod and the clamping plates is enhanced; the connecting rod is connected with the clamping plate through the nut, and when parts need to be overhauled or replaced, the connecting rod is convenient to detach and install.

Optionally, one end of each connecting rod is connected with a knob.

Through adopting above-mentioned technical scheme, when needing to rotate the connecting rod, bare-handed rotation takes the screwed connecting rod, not only wearing and tearing constructor's palm skin, rotatory efficiency is also than the inefficiency that uses the knob. The knob is used for rotating the connecting rod to be connected with the nut, so that the labor is saved and the efficiency is improved.

Optionally, every fixedly connected with connecting block on the arc buckle, the connecting block is located between arc buckle and the connecting rod, just the connecting block roof offsets with the connecting rod.

Through adopting above-mentioned technical scheme, do not have the contact surface originally between arc buckle and the connecting rod, connecting block of fixed connection on the arc buckle, the connecting rod is through offseting with the connecting block, to connecting block surface production pressure to the restriction arc buckle takes place to remove.

Optionally, each connecting block is provided with a through hole for the connecting rod to pass through.

Through adopting above-mentioned technical scheme, the connecting rod can also link to each other with the connecting block through the through-hole, compares in and offsets with the connecting block, and the connecting rod is more stable with being connected of connecting block, and the effect that the restriction arc buckle takes place to remove is better.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the connecting rods are arranged on two sides of each welding position, so that the effect of enhancing the connection strength of the welding positions of the pipe body is achieved;

2. the clamping plates are sleeved at the two ends of each connecting rod and detachably connected with the connecting rods, so that the connecting strength of the connecting rods is enhanced, and the clamping plates and the connecting rods are convenient to mount;

3. the nuts are connected with the two ends of the connecting rod through the threads, so that the effect that the clamping plate is tightly connected with the connecting rod is achieved.
