As shown in fig. 18, in the present embodiment, the second matching portion 87 is a convex pillar.

As shown in fig. 18 and 19, in the present embodiment, the locking plate 77 is provided with a pressed column 89, the first engaging portion 86 is a driving surface, and after the unlocking push rod 85 is pressed and moved, the first engaging portion 86 engages with the pressed column 89 to drive the locking plate 77 to move upward. The driving locking piece 77 is driven to move upwards after the unlocking push rod 85 is pushed through the matching of the driving surface and the pressed column 89.

As shown in fig. 18 and 19, in the present embodiment, the base 1 has an L-shaped plate 90, the L-shaped plate 90 includes a vertical plate 91 and a horizontal plate 92 located at the upper end of the vertical plate 91, the upper end of the locking plate 77 is slidably disposed on the horizontal plate 92, and the first spring 78 is sleeved on the upper portion of the locking plate 77 and the upper end of the locking plate abuts against the horizontal plate 92. The L-shaped plate 90 facilitates reliable stress of the locking tab 77.

As shown in fig. 18 and 19, in the present embodiment, the vertical plate 91 has a bar-shaped vertical hole 93 through which the end of the pressure receiving column 89 passes. The compression post 89 and the locking piece 77 can be further limited by the strip-shaped vertical hole 93, and the structure is more reliable during movement.

As shown in fig. 18 and 19, in the present embodiment, the base 1 has a first vertical portion 94, one end of the blocking piece 79 is slidably disposed on the first vertical portion 94, the second spring 81 is sleeved on one end of the blocking piece 79 adjacent to the first vertical portion 94, and one end of the second spring 81 abuts against the first vertical portion 94. The provision of the first upright portion 94 facilitates the mounting of the flap 79 and the second spring 81.

As shown in fig. 18, in the present embodiment, the base 1 has a second vertical portion 95, one end of the unlocking push rod 85 is slidably disposed on the second vertical portion 95, the third spring 88 is sleeved on one end of the unlocking push rod 85 adjacent to the second vertical portion 95, and one end of the third spring 88 abuts against the second vertical portion 95. The provision of the second upright portion 95 facilitates the installation of the unlocking push rod 85 and the third spring 88.

As shown in fig. 1 and 18, in this embodiment, the unlocking push rod 85 also has a trigger 96, the trigger 96 being adapted to engage the first microswitch 63 of the hand cranking interlock. The unlocking push rod 85 also has a locking groove 97, the locking groove 97 being adapted to cooperate with the second locking portion 47 of the hand cranking interlock to lock the unlocking push rod 85.

The matching relation between the opening and closing interlocking mechanism and the linkage unlocking mechanism of the embodiment is as follows: the unlocking push rod is in a first working position in an initial state, the lower end of the locking plate penetrates through the base to be matched with an external structure at the moment to limit the base, the lower end of the first locking part of the unlocking baffle also penetrates through the base to be matched with the external structure to limit the base, and the second locking part is inserted into the locking groove, so that the unlocking push rod cannot be pressed; when the opening and closing hook plate is operated to rotate, the unlocking baffle is driven to move upwards, the first locking part is separated from the external structure, the second locking part is separated from the locking groove, the unlocking push rod can be pressed at the moment, and when the unlocking push rod is pressed, the first working position can be switched to the second working position.

The above only is the preferred embodiment of the present invention, not therefore the limit the patent protection scope of the present invention, all applications the equivalent structure transformation made by the contents of the specification and the drawings of the present invention is directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
