As shown in fig. 9, the fixed base 4 is formed with a vertical positioning long hole 401, the vertical positioning long hole 401 is extended in the left-right direction, as shown in fig. 12, the second positioning eccentric shaft 2 includes a pin column portion 21 and an eccentric column portion 22, the pin column portion 21 and the eccentric column portion 22 are eccentrically disposed with respect to each other, as shown in fig. 1, 2 and 5, the eccentric column portion 22 is disposed in the vertical positioning long hole 401, the pin column portion 21 is rotatably fitted to the slide base 3, and as shown in fig. 12 and 13, the cross section of the eccentric column portion 22 is formed in a shape of a lelo triangle.

As shown in fig. 1, when the first positioning eccentric shaft 1 is rotated, the first positioning eccentric shaft 1 can drive the sliding seat 3 to move and position along the left-right direction, and the fixed seat 4 can position along the left-right direction because the fixed seat 4 is hinged with the sliding seat 3 through the pin shaft 5; when the second positioning eccentric shaft 2 is rotated, due to the gravity action of the door body, the eccentric column part 22 of the second positioning eccentric shaft 2 is in contact connection with the upper inner wall of the up-down positioning long hole 401, so that the second positioning eccentric shaft 2 can drive the fixed seat 4 to move up and down for positioning; when the front and back positioning screws 6 are rotated, the front and back positioning screws 6 are subjected to the axial limiting action of the sliding seat 3, so that the part of the fixed seat 4 connected with the second positioning eccentric shaft 2 moves forwards or backwards, the fixed seat 4 is actually swung and positioned because the fixed seat 4 is hinged with the sliding seat 3 through the pin shaft 5, when the positioning of the fixed seat 4 is finished, the top fastening screw 10 is screwed, the thrust generated by the top fastening screw 10 can pull the fixed seat 4 away from the sliding seat 3, but because the fixed seat 4 is hinged with the sliding seat 3 through the pin shaft 5, the thrust generated by the top fastening screw 10 can enable the pin shaft 5 to be simultaneously clung to the fixed seat 4 and the sliding seat 3, the thrust generated by the top fastening screw 10 can enable the front and back positioning screws 6 to be simultaneously clung to the fixed seat 4 and the sliding seat 3, so that the gap between the fixed seat 4 and the sliding seat 3 is eliminated, and the static friction force between the fixed seat 4 and the sliding seat 3 is greatly increased, the fixed seat 4 and the sliding seat 3 are completely fixed relatively, and the phenomenon that the door body is loosened in practical use is avoided.

The characteristics of the reuleaux triangle are that it can rotate freely between two parallel straight lines and always remain in contact with both of them. Therefore, the utility model utilizes the characteristics of the Leluo triangle to enable the eccentric column part 22 to rotate between the upper inner wall of the up-down positioning long hole 401 and the lower inner wall of the up-down positioning long hole 401; as shown in fig. 1 in conjunction with fig. 14, when the long vertical positioning hole 401 is in the neutral position (i.e., the fixed base 4 is at the middle position of the total positioning stroke in the vertical direction), the distance in the left-right direction from the contact point of the upper inner wall of the long vertical positioning hole 401 and the eccentric column portion 22 to the axis of the pin column portion 21 (i.e., the dimension "L1" in fig. 14) is relatively small, as shown in fig. 17, and when the cross section of the eccentric column portion 22 is assumed to be circular, the distance in the left-right direction from the contact point of the upper inner wall of the long vertical positioning hole 401 and the eccentric column portion 22 to the axis of the pin column portion 21 (i.e., the dimension "L2" in fig. 17) is relatively large, with the result that the structure shown in fig. 14 makes the moment applied to the eccentric column portion 22 by the upper inner wall of the long vertical positioning hole 401 due to the gravity of the door body relatively small around the axis of the pin column portion 21, which is advantageous for the door body to cause the eccentric column portion to turn over when the door body is in the neutral position stroke, that is, the door body can effectively stay at the middle position of the vertical position adjusting stroke. Fig. 16 schematically shows a contact state between the offset pillar portion 22 having the shape of the lelo triangle and the vertical positioning long hole 401 in the high position state, and fig. 15 schematically shows a contact state between the offset pillar portion 22 having the shape of the lelo triangle and the vertical positioning long hole 401 in the low position state, and it can be seen from fig. 15 and 16 that a force applied to the offset pillar portion 22 by an upper inner wall of the vertical positioning long hole 401 by the weight of the door body passes through an axis of the pillar portion 21, so that the offset pillar portion 22 is not easily turned over after the active positioning is completed, and the door body can stably stay at the highest or lowest position of the vertical positioning.
