The clamping belt 6 and the arc-shaped clamping block 5 form a pressure ring that allows the hose with a stainless steel braided mesh to pass through. One end of the fixing rod 2 is connected to the arc-shaped clamping block 5. The middle part of the clamping block 5 and the other end are fixedly connected to the first handle 10 through the first bolt 11. At the same time, the first bolt 11 passes through the center of the tightening wheel 1, and the tightening wheel 1 can rotate freely along the first bolt 11. The second handle 8 is fixedly connected to the tightening wheel 1 and makes the second handle 8 located on the side of the first handle 10 close to the arc-shaped clamping block 5. The second handle 8 is operated to drive the tightening wheel 1 to rotate in the direction close to the first handle 10, tighten the clamping belt 6 to reduce the circumference of the pressure ring, and fix the hose with the stainless steel braided mesh.

[0028] In a specific implementation, the length of the fixing rod 2 is greater than the radius of the tightening wheel 1, so that the arc clamping block 5 is staggered with the tightening wheel 1, and the arc clamping block 5 bends in the direction away from the tightening wheel 1. When the pressure ring fixes the hose and the stainless steel braided mesh, the hose and the tightening wheel 1 will not interfere with each other.

When the second handle 8 drives the tightening wheel 1 to rotate close to the first handle 10, the second handle 8 is arranged parallel to the first handle 1, which is convenient for holding the second handle 8 and the first handle 10 with one hand.

[0035] In some embodiments, the arc of the arc-shaped clamp block 5 is (2 / 3)π-(5 / 6)π, which is suitable for cooperating with the clamping belt 6 to fix hoses with different outer diameters.

[0036] In some embodiments, the clamping belt 6 is a stainless steel braided belt with good corrosion resistance and long practical life.

The fixing rod 2 connected to the arc-shaped clamping block 5 is fixedly connected to the first handle 10 through a first bolt 11. At the same time, the first bolt 11 passes through the center of the tightening wheel 1 and the tightening wheel 1 can rotate freely along the first bolt 11. The second handle 8 is fixedly connected to the tightening wheel 1. When the second handle 8 is operated to drive the tightening wheel 1 to rotate in the direction close to the first handle 10, the clamping belt 6 can be tightened to reduce the circumference of the compression ring, and the hose provided with the stainless steel braided mesh can be fixed, so as to achieve a firm and reliable fixation of the hose provided with the stainless steel braided mesh, which is conducive to the buckling of the explosion-proof sleeve, improves the installation quality of the explosion-proof sleeve, and avoids the safety hazard of manually fixing the stainless steel braided mesh and the hose for buckling the explosion-proof sleeve.
