A windshield wiper device is provided that enables high-precision installation of retaining members in a short time. The wiper device includes: a first pivot and a second pivot connected to a wiper arm; a drive unit for rotating the first pivot; a connecting unit connected to the second pivot and the drive unit for synchronously rotating the two pivots; and a first retaining member and a second retaining member for securing each of the pivots to the vehicle body. The second retaining member includes: a body portion for rotatably supporting the second pivot; and three support portions protruding from the body portion. The first and third support portions include: a fixed portion secured by bolts; and a locking pin disposed on the fixed portion for engaging with the vehicle body.

The application discloses a super-large linear motor adjustable stator support structure and relates to the field of super-large linear motor machine tools. The super-large linear motor adjustable stator support structure comprises a bed body, a T-shaped back plate provided on the bed body and used for mounting an external support, corresponding stators provided on the two sides of the T-shaped back plate, corresponding movers provided on the sides, away from each other, of the two stators, and corresponding adjusting bolts and fixing bolts respectively screwed on the T-shaped back plate. The T-shaped back plate is modularly integrated and dynamically adjusted with the special adjusting bolts and the fixing bolts, so that high-precision installation of the stators, self-adaptive compensation of gaps and magnetic attraction force offset can be realized, the width of the bottom transversely extending flange is convenient for mounting and fixing the external support, meanwhile, the bending deformation caused by the magnetic attraction force can be inhibited, and compared with the prior art, the stator support of the application can reduce the machining cost and the maintenance cost of the bed body, and improve the tolerance compatibility and the environmental adaptability.
