Main body 52 has bearing-surface 54, bearing-surface 54 have with framework 40 with the shape of the shape complementarity in the face faced by it.Therefore, when main body 52 contacts with framework 40, bearing-surface 54 and framework prevent framework 40 around any rotary motion of its transverse axis B with the shape of the face complementation faced by it.
Main body 52 also has ratchet 56, and ratchet 56 is laterally biased relative to main body 52, and ratchet 56 roughly longitudinally extends, and ratchet 56 has free end 56a, and free end 56a is suitable for contacting with ratchet 36, to prevent ratchet 36 from moving towards its enable position.
As seen in Fig. 3, when locking device 50 is connected to control device 10, the bearing-surface 52 of main body 52 and the free end 56a of ratchet 56 bear against framework 40 and ratchet 36 respectively, therefore stop that these parts 40,36 move relative to support 12.Therefore control device 10 is mechanically locked in applicable position.
By main body 52 being inserted in support 12 between parallel plate 14, locking device 50 is assembled into control device 10.
Therefore, the transverse width of main body 52 equals the lateral separation between two parallel plates 14 haply, therefore relative to support 12 laterally positioning body 52.
Main body 52 also has two laterally projecting shoulder 58, two shoulders 58 and is distributed on the both sides of main body 52.
Each in these shoulders 58 is suitable for being placed between lamellar body 15s, 15i of plate 14, and the vertical size of shoulder 58 is substantially equal to the vertical distance between two lamellar bodies 15s, 15i of plate 14, thus relative to support 12 positioning body 52 vertically.Each shoulder 58 also longitudinally extends, thus prevents main body 52 relative to any pivotable of support 12 in vertical fore-and-aft plane.
