[0108] The method of using this embodiment is as follows:

[0109] In actual work, the staff moves the second support member 410 to adjust the horizontal position of the latch member 220 on the base member 110. After adjusting to a suitable position, the staff rotates the first fixing member 330 to fix the second support member 410.

[0110] Then, the staff moves the fixed seat member 210 to adjust the height position of the bayonet member 220 on the base member 110. After adjusting to a suitable position, the staff rotates the second fixing member 430 to fix the fixed seat member 210.

[0111] Then, the staff inserts and connects the joint of the wiper arm with the bayonet member 220, hooks the first end of the tension spring with the rod inside the wiper arm, and hooks the second end of the tension spring with the hook member 520;

[0112] Finally, the staff starts the driving member 540, so that the driving member 540 drives the sliding shaft 510 to move, thereby achieving the stretching of the tension spring. After the driving member 540 stretches the tension spring to a suitable position, the staff can hold the push-pull rod 550 and fine-tune the stretching length of the tension spring, thereby achieving the connection between the second end of the tension spring and the hook on the wiper arm, thereby achieving the installation of the tension spring.

[0113] The advantage of this embodiment is that by arranging the first adjusting component and the second adjusting component on the base component, the horizontal position and the height position of the fixing component on the base component can be adjusted, and thus it can be suitable for the installation operation of the tension spring of wiper arms of different sizes and models; by arranging the push-pull component on the base component, the tension spring can be stretched by the push-pull component, thereby reducing the work intensity of the staff and improving the assembly efficiency.
