The positioning rack for electrothermo straps includes a base with multiple arms extending radially from the base and each arm is connected with a board. Two engaging members each have a neck connected to the arm and an enlarged block IS connected to the neck. Each board is made of thermal insulation material and has multiple positioning recesses defined in two sides thereof. Each board has two holes and two secure slots which communicate with the two holes respectively. The block passes through the hole and the neck is moved to be engaged with the secure slot to connect the board to the arm. At least two electrothermal straps are engaged with the positioning recesses and spirally mounted to the boards. The boards can be easily replaced without use of rivets. |
