By adopting the above technical scheme, bellows has good deformability, while can protect to compressed spring, It reduces it to be corroded by the external world, to improve its service life.

Further preferably are as follows: one end on the extension rod far from the rotating bar, which is provided with, pushes against end, the abutting end It is arranged in the arc of outwardly convex.

By adopting the above technical scheme, the abutting end of arc setting and the top of car windscreen can be reduced after pushing against to automobile The damage of front window.

Further preferably are as follows: have additional rubber pad on the abutting end.

By adopting the above technical scheme, in use, rubber pad is located in extension when extension rod is pushed against at the top of car windscreen Between bar and car windscreen, the top and extension rod of car windscreen are protected, the service life of extension rod is extended.

Further preferably are as follows: be rotatably connected to ball on the abutting end.

By adopting the above technical scheme, the frictional force that extension rod is subject at the top of the car windscreen in moving process is reduced, is improved The working efficiency of windscreen wiper device.

Further preferably are as follows: pinboard is provided between the elastic doctor blade and the rotating bar, the pinboard is in institute The projection in rotating bar is stated to fall in the rotating bar；The elastic doctor blade is set from the pinboard towards Wipe assembly extension It sets.

By adopting the above technical scheme, increase the range that elastic doctor blade can clean, improve cleaning effect.

Further preferably are as follows: be formed with cushion space between the elastic doctor blade and the Wipe assembly.

By adopting the above technical scheme, when compressed spring moves, Wipe assembly can rotate relative to elastic doctor blade, delay Space can be provided to Wipe assembly by rushing space, and reducing the two and being in contact leads to the case where damaging appearance.

In conclusion the utility model has the following beneficial effects: by passing through compressed spring connection one in rotating bar Root extension rod, and Wipe assembly is set on extension rod, it is separate on extension rod to turn when rotating bar turns at the top of car windscreen One end of lever is relatively rotated by the limit at the top of car windscreen, extension rod with rotating bar, while Wipe assembly wipes The top of car windscreen has the advantages that improve cleaning effect.
