The first transmission member 140 is connected with the first connecting member 120, and the first transmission member 140 is rotated to drive the first connecting member 120 to synchronously rotate around the first axis, so that the main body 110 and the first compressing member 130 move along the first axis direction respectively, and the first compressing member 130 is in compression joint with the sealing ring 1000. The first axis direction is schematically shown by arrow X, and it is understood that the first axis is the central axis of the first connecting member 120, and is parallel to the first axis direction. Fig. 1 is a schematic view of a press-fit tool 100 in a use view, in the view of fig. 1, a first axis direction is perpendicular to an axial direction of an impeller.

Specifically, the first transmission member 140 is sleeved on the outer peripheral wall of the first connecting member 120. By rotating the first transmission member 140, the first transmission member is driven to synchronously rotate, so that the screwing depth of the first connection member 120 relative to the impeller is changed, that is, the distance between the main body 110 and the impeller along the first axis direction is changed, and the first pressing member 130 connected to the main body 110 gradually approaches the sealing ring 1000 along the first axis direction until the first pressing member is completely pressed against the sealing ring 1000.

As shown in fig. 2 to 4, in one embodiment, the press-fit tool 100 further includes a first operating member 150 and a first toggle member 160 connected to the first operating member 150. Through rotating first operating piece 150, drive first stirring piece 160 and rotate to make first stirring piece 160 overlap joint with first driving piece 140, and then stir first driving piece 140 and rotate around the first axis, and then realize first clamp 130 and sealing washer 1000 along the interval adjustment of first axis direction, make first clamp 130 can press in sealing washer 1000, and with its mounting groove of pressing in the bearing. By providing the first operating member 150 and the first toggle member 160, the adjustment operation is facilitated.

When the first operating member 150 drives the first toggle member 160 to deflect, the elastic member 180 is compressed. The rotation amplitude of the first toggle member 160 is limited by the elastic force of the elastic member 180. In addition, when the external force acting on the first operating member 150 is removed, the elastic force of the elastic member 180 can also drive the first toggle member 160 to automatically reset, so that the first transmission member 140 can rotate in a larger stroke in a limited space. The elastic member may be a spring.

As shown in fig. 3 and 4, in one embodiment, the press-fit tool 100 further includes a mounting plate 190 and a first connecting shaft, and one end of the first toggle member 160 is rotatably connected to the mounting plate 190 through the first connecting shaft; the other end of the first toggle member 160 can overlap the first transmission member 140. By providing the mounting plate 190, a certain supporting effect is provided for the second transmission member 170, the elastic member, and the like. The first stirring piece 160 is rotatably installed on the mounting plate 190 through the first connecting piece 120, so that the deflection direction of the first stirring piece 160 is better limited, the possibility of position deviation of the first stirring piece 160 is reduced, and the reliability of stirring effect is ensured.

As shown in fig. 2 and fig. 5, in one embodiment, the press-fit tool 100 further includes a second connecting shaft 210, and one end of the second connecting shaft 210 protrudes from the first surface of the main body 110; the first operating member 150 is coupled to one end of the second coupling shaft 210. By projecting the first operating member 150 from the surface of the main body 110, that is, the first operating member 150 is exposed, it is more convenient for an operator to rotate the first transmission member 140 and the first connecting member 120.

By arranging the first operating member 150 in the accommodating groove 111, the surface of the main body 110 is smoother, and the overall aesthetic effect of the press-fitting tool 100 is improved. Meanwhile, the occupied space of the first operating member 150 and the main body 110 along the first axis direction can be reduced, so that the press-fitting tool 100 is more compact.

As shown in fig. 2 to 4, in one embodiment, the first transmission member 140 is a gear, so that the first stirring member 160 can extend into a tooth slot of the gear, so that the contact area between the first stirring member 160 and the gear can be increased, thereby being more beneficial to the transmission of stirring force. Wherein, the first connecting piece 120 is configured with a limiting groove, and the gear is sleeved on the groove wall of the limiting groove.
