Through setting up outer sleeve 31 and inner sleeve 32, make the inner edge of inner sleeve 32 and the upper end outer peripheral face threaded connection of base 1, the upper end external diameter size of base 1 is greater than the radial dimension of base 1 middle section, the inner edge of outer sleeve 31 and the outer peripheral face threaded connection of end cover sleeve 8, and the screw thread rotation direction of inner sleeve 32 inner edge is opposite with the screw thread rotation direction of outer sleeve 31 inner edge, and end cover sleeve 8 and base 1 axial sliding connection and circumference spacing, specifically, the middle section lateral wall of base 1 has the spacing that extends axially, the inner edge of end cover sleeve 8 has the spacing groove with spacing location complex, so can know when movable sleeve 3 rotates down relative to base 1 and feeds, end cover sleeve 8 can move down relative to outer sleeve 31, owing to form cavity one 33 between outer sleeve 31, inner sleeve 32, main shaft 2 and the upper end of base 1, end cover sleeve 8, form cavity two 34 between inner sleeve 32 and the outer side wall of base 1, the passageway 35 of communicating cavity one 33 and cavity two 34 has between 31, the upper end inner sleeve 32's upper end edge has the spacing that extends axially, the upper end sleeve 32 has the spacing groove that is located with spacing, the air pressure of cavity 33 is cut-off and the inside gap is formed to the cavity of the inside of cavity 34 is not influenced in the change in the air pressure state, the inside gap that the cavity is not had no influence from the inside gap is formed to the cavity is formed to the gap between the cavity of the inside is formed to the cavity is broken down, the gap is difficult to change, and the inside is difficult to take out in the inside gap between the cavity is because the cavity is difficult to take down. The upper end of the channel 35 is located at the joint of the upper end of the inner sleeve 32 and the outer sleeve 31, and the lower end of the channel 35 is located at the joint of the lower end of the inner sleeve 32 and the outer sleeve 31, and the first cavity 33 is located higher than the second cavity 34, so that even if part of impurities invade the second cavity 34 after long-term use, the impurities are difficult to continuously move upwards to invade the first cavity 33 under the influence of maze and dead weight, and the smoothness is further ensured.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
