[0028] Embodiment one

[0029] In order to solve the problem of the existing excavator wiper motor arm blade assembly support in the prior art that the installation is not firm when the wiper arm and the wiper blade of the wiper are connected, the following technical scheme is disclosed, and specific reference can be made to Figure 1 , Figure 2 , Figure 3 , Figure 4The device includes an excavator wiper arm body 1, a mounting block 2, and an excavator wiper blade body 4. The mounting block 2 is connected to one side of the excavator wiper arm body 1, and an insert block 6 is connected inside the mounting block 2. Both sides of the insert block 6 have rectangular locking holes 601. One end of a locking block 703 extends into the locking hole 601 to fix the insert block 6. A movable seat 8 is connected to one side of the insert block 6, and a hinge seat 5 is connected to one side of the movable seat 8. The movable seat 8 and the hinge seat 5 movably connect the insert block 6 to the excavator wiper blade body 4 via the movable seat 8. The excavator wiper blade body 4 is connected to one side of the hinge seat 5. A cleaning strip 401, made of synthetic rubber, is provided on one side of the excavator wiper blade body 4. The device also includes a mounting block. Both sides of the inner cavity 2 are provided with driving cavities 201, and each driving cavity 201 is provided with a fixing mechanism 7. The fixing mechanism 7 includes a rotating shaft 701, which is located inside the driving cavity 201. A gear 702 is sleeved on the outer side of the rotating shaft 701, and a locking block 703 is engaged on one side of the gear 702. A guide post 704 passes through one side of the locking block 703, and both ends of the guide post 704 are connected to the inner wall of the driving cavity 201. Tooth blocks are evenly arranged on one side of the locking block 703, and the locking block 703 is engaged with the gear 702 through the tooth blocks. An insertion hole 202 is provided on one side of the mounting block 2, and a through hole passes through the insertion hole 202 and the driving cavity 201. The width of the through hole is greater than the width of the locking block 703.
