Fig. 3 is the structural representation at the seat of honour.
In figure: 1-plunger; The 2-seat of honour; Lower of 3-; 4-guide finger; 5-pin rod; 11-guiding groove; Groove under 12-; 13-middle slot; The upper groove of 14-; 15-lower support face; 16-jack; Guide hole under 17-; The main boss of 21-; The upper guide hole of 22-; 23-the second secondary support surface; 24-the first secondary support surface; 25-safety pin; 26-concave station face.
Embodiment
As Figure 1-3, many gears of one supporting pin described in the embodiment of the present invention, mainly comprise plunger 1, pin rod 5, the seat of honour 2 and lower 3, plunger 1 is fixedly connected on pin rod 5 tops, both one machine shapings, pin rod 5 is through in the upper guide hole at the seat of honour 2 and lower 's 3 lower guide hole, and can slide up and down along guide hole.
The seat of honour 2 is flexibly connected with lower 3, on the seat of honour 2, be provided with main boss 21, lower seat 3 is provided with the step trough of different heights, and step trough mainly comprises groove 14, middle slot 13 and lower groove 12, main boss 21 coordinates with the step trough of different heights, to realize the object of different gear height.
On main boss 21, be provided with a concave station face 26, on concave station face 26, be provided with a safety pin 25, safety pin 25 can rotate with the seat of honour 2, and can be inserted in the jack 16 of lower 3, now the seat of honour 2 is with lower 3 along circumferentially temporary fixed, and object is to prevent that the seat of honour 2 from falling into landing automatically after step trough.
Each step trough top is respectively arranged with supporting surface 15, the perpendicular distance of lower support face 15 and each step trough equals the perpendicular distance of concave station face 26 and main boss 21, when main boss 21 contacts with step trough, concave station face 26 also contacts with the lower support face 15 of respective steps groove, is provided with a jack on lower support face 15.
The seat of honour 2 is also provided with the first secondary support surface 24 and the second secondary support surface 23, the perpendicular distance of the first secondary support surface 24 and concave station face 26 equals the distance between the lower support face of groove 14 and the lower support face 15 of lower groove 12, and the perpendicular distance of the second secondary support surface 23 and concave station face 26 equals the distance between the lower support face of groove 14 and the lower support face 15 of middle slot 13.The object of design is like this, when the concave station face 26 on main boss 21 contacts with lower support face 15, can guarantee to also have another one secondary support surface and lower support face 15 to keep in touch, and has improved the reliability and stability that support.
One guide finger 4 is installed on pin rod 5, the interior slip of a guiding groove 11 that guide finger 4 can arrange on lower 3, spacing for to pin rod 5 vertical directions pulled out pin rod completely preventing when the seat of honour 2 drives pin rod 5 upwards to stir.
