When the wire fixing support 100 is arranged in the molding device 1000, the stability of the lead wires in the molding device 1000 can be better ensured through the wire fixing support 100, so that the molding device 1000 works more stably and has longer service life.

For convenience of description, the wire fixing bracket 100 will be specifically described with reference to the example that the wire fixing bracket 100 is suitable for use in a blower, and other devices may be implemented with reference to the adaptation.

The wire fixing bracket 100 may be installed and fixed in a duct of the blower, and the first guide wall 1 and the second guide wall 2 are also substantially cylindrical because the duct is substantially cylindrical. Preferably, the first guiding wall 1 is fixedly sleeved on the inner side of the air duct, one end of the air duct, provided with the air blowing port, is set as the front end, and the guiding end wall 3 is arranged close to the rear ends of the first guiding wall 1 and the second guiding wall 2. A circuit board structure 300 may be disposed in the air duct, and the circuit board structure 300 is disposed at the rear side of the guide end wall 3 and connected to the wire fixing bracket 100. The electronic devices, such as fans or heating structures 400, located on the front side of the wire fixing frame 100 need to be connected to the circuit board structure 300 through the wire guiding wires, so that the wire guiding wires can pass through the wire guiding holes 41, so that the wire guiding wires can be regularly accommodated in the wire guiding holes 41 and better electrically connected to the circuit board structure 300.

In order to facilitate the connection of the conductive wire in the via hole 41, the first opening 411 is formed at one side of the via hole 41, and the conductive wire can be clamped in the via hole 41 from the first opening 411, so that the operation of clamping the conductive wire is more convenient compared with a through hole without an opening.
