Air acting surface 54. 201104074 According to the view direction of the sixth figure and the three-dimensional space as a description, the central point P〇 of the aforementioned implant shaft hole 5U) is parallel to the horizontal plane or in the χγ plane, and the center point F〇 of the pusher action surface 54 is as described above. The line center of the central point ρ of the frame shaft hole 51 is parallel to the z-axis, which is perpendicular to the χγ level 0 plane; the plane center point of the pushing action surface 54? . Extending in the direction of the x-axis, the perpendicular to the auto-pushing action surface 54 (the perpendicular line (and intersecting with the χ γ plane at the point 卩丨') forms a length distance from the central point ρ0 as the sixth Compared with the sixteen maps (in order to highlight the planar state of the thrusting action surface, the other secondary components on the piston head are not shown in the sixth and sixteenth figures), the conventional pushing surface 982 of the piston body 98 2 axial connection &, the center point of the plane of the push-pull effect 982 ^ is perpendicular to the perpendicular line of the self-propelled action surface 982 extending in the direction of the 2 axes, and the connection line and the vertical line are heavy In the state of the crucible, the connecting line in the piston body 5 of the present invention does not overlap with the vertical line, and the crucible is formed with a distance length/, and further, the pushing action surface 54 of the piston head 52 is not in phase with the crucible surface. In parallel, φ forms a θι with an inclination angle other than zero, that is, the urging surface 54 of the piston head 52 assumes an angle and a slope with respect to the piston rod 51. Please refer to the seventh and eighth figures, The positioning plate 2 of the casing 1 has an upper circular hole 22 and a lower circular hole 21, There is a central axis point ρ4, ρ3, and the imaginary line 2 and 妁 extending from the central axis points Ρ4 and Ρ3 are parallel to the χγ horizontal plane.
