At this time, the telescopic assembly is compressed until the limit rod 108 leaves the mounting block 114, and the limit rod 108 releases the limit fixation of the mounting block 114 and the blade 115. At this time, the operator pulls the blade 115 outward, and the blade 115 and the mounting block 114 are pulled out of the mounting groove 102 and replaced with a new blade 115. In this way, the damaged blade 115 can be disassembled and replaced individually without replacing the entire deflector 101, thereby reducing the cost of use.

[0022] Furthermore, both ends of the telescopic spring 106 are fixedly connected to the support block 104 and the support plate 107 , respectively.

[0023] In this embodiment, when the blade 115 on the deflector 101 is damaged, the support plate 107 next to the damaged blade 115 is pulled, and the support plate 107 moves away from the mounting block 114 and the blade 115. At this time, the telescopic spring 106 and the telescopic rod 105 are compressed until the limit rod 108 leaves the mounting block 114, and the limit rod 108 releases the limit fixation of the mounting block 114 and the blade 115. At this time, the operator pulls the blade 115 outward, and the blade 115 and the mounting block 114 are pulled out of the mounting groove 102 and replaced with a new blade 115.

[0028] In this embodiment, after the blade 115 is replaced, the two ends of the protective cover 111 are respectively inserted into the two clips 110, and the cover is placed above the deflector 101, and then the protective cover 111 and the deflector 101 are fixed together by four bolts 112 to protect the components above the deflector 101.

[0029] When using the present invention to replace the damaged blade 115, the four bolts 112 are removed, the protective cover 111 is pulled out from the two clips 110, and then the support plate 107 next to the damaged blade 115 is pulled, and the support plate 107 moves away from the mounting block 114 and the blade 115. At this time, the telescopic spring 106 and the telescopic rod 105 are compressed until the limiting rod 108 leaves the mounting block 114, and the limiting rod 108 releases the limiting fixation of the mounting block 114 and the blade 115. At this time, the operator pulls the blade 115 outward, and the blade 115 and the mounting block 114 are pulled out from the mounting slot 102. Then insert the mounting block 114 under the new blade 115 into the mounting groove 102, loosen the support plate 107, and the telescopic spring 106 extends under the action of its own elastic potential energy and passes through the mounting block 114. When the blade 115 is replaced, the two ends of the protective cover 111 are respectively inserted into the two clamping strips 110, and the cover is placed above the deflector 101.
