The width j of the fool-proof limiting portion 34 (as shown in FIG. 9B ) is greater than or equal to the distance i between the end point of the latch 41 of the wiper lever 4 and the inner side of the shoulder 42 . When the seat 3 is assembled, when the pin 41 of the wiper rod 4 is combined with the sleeve 1 and the base 3, it will not be able to be inserted, because the width j is greater than or equal to the distance i, and the foolproof stopper 34 will first interfere with the pin 41 Together with the shoulder 42, the pin 41 cannot be inserted into the sleeve 1 and the fastener 2, which can provide a fool-proof function.

Please refer to Fig. 8 to Fig. 9, the wiper rod 4 and the base 3 are slightly horizontal and located on the base 3 after the assembly of the latch force stabilization sleeve is completed, and the angle ≧ 0 degrees is set and then pressed down, and the The wiper rod 4 of the assembly sleeve 1 is directly pressed down horizontally from top to bottom, so that the first stopper part 12 and the second stopper part 13 are respectively accommodated in the first positioning groove 32 and the second positioning groove of the base 3 33, and the sleeve body 11 is correspondingly accommodated in the clamping fixing groove 31, and the sleeve body 11 is pressed to clamp the fixing groove 31 to achieve the purpose of assembly. After the assembly of the wiper lever 4 , the sleeve 1 and the base 3 , the inner edge of the mechanism of the wiper lever 4 away from the base of the pin 41 does not interfere with the base 3 .

Basically, as shown in FIG. 1 , the latch 41 of the wiper lever 4 has no fixing function, and its fixing (locking) function is achieved by the shoulder 42 . Therefore, when the wiper is working, there will be two kinds of forces that interact on different horizontal lines, and these two forces will interfere with each other, resulting in unstable performance of the wiper when it is working. In addition to the function of protecting the bolt 41, when the present invention adds the bolt force stabilizing sleeve, the most important thing is to use the power of the wiper lever 4 to use the sleeve 1 to transfer the multiple force applied by the original wiper lever 4. It is transformed into a single application force, without being locked by the shoulder 42 of the wiper lever 4 , by means of a single application force, the performance stability of the wiper during operation is improved.
