[0002] The split wall-mounted air conditioner is the most common style of household air conditioner, which is divided into an indoor unit and an outdoor unit. The indoor unit is fixed to the wall in a wall-mounted manner. The existing wall-mounted air conditioner indoor unit is equipped with an evaporator, a cross-flow fan, an air duct, etc., and is covered by a shell to form a complete machine. A vent is formed at the lower part of the shell, and the air outlet of the air duct extends to the vent; an air guide plate is installed at the vent, and the air supply direction is adjusted by the swing of the air guide plate. After the air duct pipe is processed, it is necessary to measure its deformation to detect the deformation position of the pipe.

[0003] At present, the measurement equipment for the deformation of the air duct pipe generally uses a measuring ruler for measurement. However, it is very difficult to measure the deformation position of the pipeline with a measuring ruler. It is necessary to hold the measuring ruler to measure section by section, which is inefficient and cannot quickly measure the deformation position of the air duct pipe. Utility Model Content

[0010] Preferably, an arc-shaped abutment plate is welded to one end of each of the supporting top rods away from the fixing collar, and the curved surface of each of the arc-shaped abutment plates abuts against the inner wall of the cylindrical air duct tube.

[0011] Preferably, a non-slip rubber pad is bonded to the back surface of each of the arc-shaped abutment plates, and the non-slip rubber pad is in frictional contact with the inner wall of the cylindrical air duct tube.

[0012] Preferably, both ends of the connecting drive rod are welded with extension rods, and one of the extension rods is connected to the rotating motor.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:
