On, push pedal (22) motion grasps, with galvanic electricity, the contact (32-1) that support (31) presses auxiliary switch (32), and auxiliary contact first draws
Face (26-4), auxiliary contact second pulling face (26-5), auxiliary contact the 3rd pulling face (26-6) are highly different, draw operations bar
(42) pass through in the traction of auxiliary contact first pulling face (26-4), auxiliary contact second pulling face (26-5) and auxiliary contact the 3rd
Face (26-6) is upper to move, and elevating movement made by draw operations bar (42), and draw operations bar (42) is in auxiliary contact first pulling face
(26-4) touch link position auxiliary switch when above, draw operations bar (42) is on auxiliary contact second pulling face (26-5) simultaneously
When can successively touch link position auxiliary switch and testing position auxiliary switch, when auxiliary contact the 3rd pulling face (26-6) is upper not
Touch location aided rebroadcast switch；Three position towing plates (51) are provided with the first trussed shore (51-1), the second trussed shore (51-2) and traction
Plate spacing hole (51-3), towing plate spacing hole (51-3) limit three position towing plates (51) rotation, the first trussed shore (51-1) with
Three location positioning display pulling face (26-7) match, and the second towing pad (51-2) traction rack (52) moves, and tooth bar (52) is transported
Dynamic band moving gear (53) rotates, and gear (53) is provided with indicateing arm (53-1), and indicateing arm (53-1) points on position display plate
Tick lables；Blocking lever (73) in rotation propulsion interlock unit (7) is placed in push pedal (22), and push pedal (22) motion is passed through
Rotation interlocking behaviour's plate (74) that blocking lever (73) touches in rotation propulsion interlock unit (7) rotates, and rotation interlocking grasps plate
(74) rotation drives interlock plate (71) to open and shakes hole (72), and shaking hole (72) is to shake to enter rotation push structure unit (6) into instrument
Passage, thus realize operate latch-up structure unit (2) with rotation push structure unit (6) interlocking.
2. a kind of low pressure draw-out type drawer according to claim 1 with combination type propulsion interlocking mechanism it is characterised in that: institute
State ratchet limiting plate (27) and be provided with ratchet limiting plate positive stop end (27-1), spacing shake-up end (27-2), ratchet limiting plate is spacing
End (27-1) is limited with ratchet limiting plate first pulling face (26-6a), ratchet limiting plate second pulling face (26-6b) cooperation, ratchet
Position plate first pulling face (26-6a), ratchet limiting plate second pulling face (26-6b) touch spacing shake-up end (27-2), thus leading
Draw ratchet limiting plate (27) to rotate, ratchet post (23-2) rotates with ratchet (23), ratchet limiting plate positive stop end (27-1) is with ratchet
Limiting plate (27) rotates, but its track is different and has intersecting, and ratchet limiting plate positive stop end (27-1) can prop up ratchet post (23-2)
And so that ratchet (23) can not be fallen.
3. a kind of low pressure draw-out type drawer according to claim 1 with combination type propulsion interlocking mechanism it is characterised in that:
In rotation push structure unit (6), rotating wheel (61) is provided with multiple helicoids (61-1), and rotating wheel guide plate (62) is provided with many
Individual guiding curved surface (62-1), guiding curved surface (62-1) mate with helicoid (61-1), rotating wheel guide plate (62) be fixed on drawer every
On plate, rotating wheel (61) is fixed on drawer, and rotating wheel (61) rotation can drive drawer to move.
