The lower end of the spoon head is shorter, and the spoon handle is longer. Reasonably adjust the direction of the spoon handle so that the telescopic oil cylinder can easily drive the spoon handle to tension the rope with a small force.

As a preference, the horizontal support bracket includes square horizontal support rods arranged on both sides of the frame body; An extension of the lumen stretch of the fixed segment.

Preferably, rubber pads are provided on the upper surfaces of the fixed section and the extension section and the side bars on both sides of the bracket facing the horizontal support bracket.

The rubber pad prevents the air duct from deforming due to the rigid connection when it is placed on the frame, and at the same time prevents the pressure generated by the tension from deforming the air duct during the tensioning process, and the elasticity of the rubber pad makes the air duct difficult to transport during transportation. It is more difficult to fall off.

Preferably, a pointer for adjusting the balance of the frame body is provided on the longitudinal rod below the connecting seat.

When working at heights, it can be remotely controlled by the ground staff to realize the safe and stable automatic installation of large tubular objects such as air ducts. And the bracket can be stably rotated to any angle with the air duct and then loosen the air duct to achieve safe and stable installation. In summary, the present invention has the following beneficial effects:
