in this embodiment, the pedal 41 is disposed above the base 1, and the initial state is the second pressing position where the pressing plate 311 is at the initial position, and the female buckle 44 and the male buckle 43 are not engaged. When a depression force is applied to the pedal 41, the state diagram of the device is shown in fig. 3, and fig. 4 is a specific structural schematic diagram of a portion of the locking control device 4 in fig. 3, along with the application of the depression force to the pedal 41, the pedal 41 moves in the first direction, and drives the pressing plate 311 to move downward, at this time, the limit swing block 45 is reset to the fifth rotation position by the third torsion spring 452, the unlocking block 421 is rotated to the fourth rotation position, the unlocking block 421 in the fourth rotation position is not contacted with the female buckle 44 in the process of moving in the first direction, and the female buckle 44 is reset to keep the first rotation position by the first torsion spring 442.

As the pedal 41 moves downwards, the male latch 43 of the pressing plate 311 moves downwards gradually until it contacts with the female latch 44 on the pedal support, and at this time, the state diagram of the apparatus is as shown in fig. 8, fig. 9 is a specific structural diagram of the locking control apparatus 4 in fig. 8, and after the male latch 43 contacts with the female latch 44, the female latch 44 is pushed to rotate, so that the female latch 44 rotates around the first rotation axis from a first rotation position to a second rotation position, and at the second rotation position, the male latch 43 can be latched into the female latch 44 or disengaged from the female latch 44. When the male buckle 43 and the female buckle 44 are not buckled originally, when the female buckle 44 rotates to the second rotating position, the male buckle 43 can be clamped into the female buckle 44; when the male and female snaps 43 and 44 are originally engaged, the male snap 43 can be disengaged from the female snap 44 when the female snap 44 is rotated to the second rotational position.

Moving from the initial state to the pressing plate 311 reaching the working position, i.e. the first pressing position, the male buckle 43 is clamped in the female buckle 44, and then the female buckle 44 is reset to the first rotating position by the first torsion spring 442, and the female buckle 44 and the male buckle 43 maintain the buckling state, at this time, the state diagram of the device is shown in fig. 10, and fig. 11 is a specific structural schematic diagram of the part of the locking control device 4 in fig. 10. Due to the engagement of the female buckle 44 and the male buckle 43, the pressing plate 311 is limited at the first pressing position where the working pressure of the hydraulic system is maintained. In order to rotate the limit swinging block 45 to the sixth rotating position when the male buckle 43 and the female buckle 44 are buckled, optionally, a limit groove can be formed in the limit swinging block 45, a limit protrusion is formed in the female buckle 44, and when the limit swinging block 45 is pressed down to be close to the female buckle 44 along with the pressing pressure plate 311, the limit protrusion also enters the limit groove to be limited in the limit groove in the process of clamping the male buckle 43 into the female buckle 44; since the female buckle 44 rotates during the process of the male buckle 43 being clamped into the female buckle 44, the rotation path can be used to arrange the limit groove, so that the female buckle 44 is reset to the first rotation position after the male buckle 43 is clamped into the female buckle 44, and the limit swing block 45 also rotates along with the reset rotation of the female buckle 44, so that the limit swing block 45 rotates from the fifth rotation position to the sixth rotation position, see fig. 11.
