Plug, in case pump depletion influences pump oil effect.It is limited by segmentation web plate when seesaw 22 is in the first, second rotation rotation stop position
Realize rotation stop in position.
Seesaw 22 is equipped with the seesaw axis hole hinged with seesaw axis 23, and seesaw 22 with seesaw axis 23 by cutting with scissors
It connects to be hinged on seesaw 22 on output revolving shaft 21, seesaw axis 23 is arranged under seesaw 22 to realize seesaw 22
With the spaced and parallel setting of axis of oscillation 20 of seesaw.Seesaw 22 has the center line parallel with seesaw axis 23, seesaw
22 about center line symmetrical setting.
In the present embodiment, the axis of oscillation of seesaw, that is, seesaw axis axial line, the axis of oscillation of seesaw is on edge
It is overlapped with the projection line of 22 vertical direction of seesaw with seesaw center line.Exist on seesaw 22 about the symmetrical two sides in center
One end far from center line is respectively equipped with the first, second bending part being bent upwards, and is lifting up wherein the first bending part 221 is equipped with
It contacts when seesaw 22 is in the first rotation rotation stop position with separation web plate to realize that seesaw 22 turns to the first rotation rotation stop
First abutting part 223 of rotation stop when position, the second bending part 222 are equipped with when seesaw 22 is in the second rotation rotation stop position and divide
Filter plate contacts the second abutting part 224 of rotation stop when realizing that seesaw 22 turns to the second rotation rotation stop position.
In the present embodiment, the axis of oscillation 20 of seesaw and seesaw 22 interval be arranged, the axis of oscillation of seesaw with
The setting of seesaw interval also makes the swing meeting fuel head center be higher than seesaw component of the seesaw component on swaying direction
Axis, even if throwing of part when 22 arbitrary end of seesaw tilts on the axis of oscillation 20 in seesaw on perpendicular
Shadow area is greater than projected area of the part on perpendicular under the axis of oscillation 20 in seesaw, can be more reliably
Guarantee the self-adapting steering of seesaw 22.
Since seesaw 22 revolves around output revolving shaft pivot center, the active force that institute's seesaw 22 is subject in rotation begins
Eventually in the horizontal direction, seesaw 22 and output revolving shaft 21 constitute seesaw component, and the fulcrum of seesaw is arranged in seesaw axis 23
On.
Seesaw 22 turns to the process of the first rotation rotation stop position when output revolving shaft 21 is rotated forward from the second rotation rotation stop position
It is as follows:
As shown in figure 3, seesaw 22 is in the second rotation rotation stop position, output revolving shaft 21 is rotated forward.Seesaw 22 is in second
