The washer installer as described in claim 6, characterized in that, When the external force on the pressure rod (3) is removed, under the action of the elastic force of the compression spring (4), the pressure rod (3) returns to its original position, causing the swing arm (7) to move towards the pressure rod (3) and return to its original position until the swing arm (7) and the wall of the first hollow straight cavity form a certain angle. During this process, the tongue plate (8) moves towards the side of the pressure rod (3) under the action of the swing arm (7). When the tongue plate (8) moves to a certain distance, it completely makes way for the space directly below the first hollow straight cavity. Then the second washer falls naturally under gravity and occupies the space directly below the first hollow straight cavity. Then repeat the process of moving and returning the pressure rod (3) to its original position, so that the tongue plate (8) pushes the second washer again and pushes the front washer under the pressure plate (11) out of the limiting groove (10).

8. The washer installer as described in claim 7, characterized in that, During this process, the operator installs the front washer onto the designated terminal block; and so on, continuing the operation until only one washer remains in the first hollow straight cavity, then the next set of washers is installed to start the work.

9. The washer installer as described in claim 1, characterized in that, A gap is provided between the outer diameter of the guide block (6) and the inner diameter of the circular tube of the support body (2), and between the inner diameter of the center hole of the guide block (6) and the outer diameter of the slender rod of the guide rod (1), so as to ensure that the guide block (6) can slide smoothly in the defined circular tube and can center and position the guide rod (1).

10. The washer installer as described in claim 9, characterized in that, When a washer with a specification of φ3 is installed, the washer is positioned by the guide rod (1); When a φ4 washer is installed, the washer is positioned by the round tube of the bracket body (2).
