In this embodiment, as shown in fig. 7 to 9, each of the first coupling housing 14 and the second coupling housing 15 is composed of two halves detachably so that the hinge opening 13 and the hinge ball 12 are located in a cavity of a corresponding one of the coupling housings when assembled.

When the vertical detection surface provided with the environment-friendly bidirectional foundation pit differential settlement monitoring device of the invention has differential settlement, for example, when the position of the second detection seat 2 descends relative to the first detection seat 1, the distance between the second detection seat 2 and the first detection seat 1 increases, the two second rotating rings 8 move backwards along the horizontal rod 9 under the driving of the second detection seat 2, the second rotating ring 8 drives one end of the third connecting rod 5 far away from the second rotating ring 8 to rotate anticlockwise around the axis of the early warning device along the first groove section 111 of the second limiting groove 11 on the first connecting shell 14, one end of the fourth connecting rod 6 far away from the second rotating ring 8 drives the second connecting shell 15 to rotate anticlockwise around the axis of the early warning device, so that the included angle between the first plane extrusion mechanism and the second plane extrusion mechanism is enlarged until the first plane extrusion mechanism and the second plane extrusion mechanism are coplanar, at this time, one end of the third connecting rod 5, which is far away from the second rotating ring 8, is located at the joint of the first groove section 111 and the second groove section 112 of the second limiting groove 11 on the first connecting shell 14, one end of the fourth connecting rod 6, which is far away from the second rotating ring 8, is located at the rear end of the first groove section 111 of the second limiting groove 11 on the second connecting shell 15, one end of the first connecting rod 3, which is far away from the first rotating ring 7, is located at the front end of the first groove section 111 of the first limiting groove 10 on the first connecting shell 14, and one end of the second connecting rod 4, which is far away from the first rotating ring 7, is located at the joint of the first groove section 111 and the second groove section 112 of the first limiting groove 10 on the second connecting shell 15; the angle between the first link 3 and the third link 5 and the angle between the second link 4 and the fourth link 6 start to increase as the second sensing seat 2 continues to move down, in the process, one end of the third connecting rod 5 far away from the second rotating ring 8 slides along the second groove section 112 of the second limiting groove 11 of the first connecting shell 14, the first connecting shell 14 is driven by the first connecting rod 3 to rotate anticlockwise around the axis which extends along the front-back direction and passes through the early warning device, one end of the second connecting rod 4 far away from the first rotating ring 7 slides along the second groove section 112 of the first limiting groove 10 of the second connecting shell 15, the second connecting shell 15 is driven by the fourth connecting rod 6 to rotate anticlockwise around the axis which extends along the front-back direction and passes through the early warning device, the first rotating part 16 and the second rotating part 17 are brought close to each other, and the electrode sheet 20 is electrically connected to one of the buzzers 21 to sound an alarm.

When the first detection seat 1 vertically descends relative to the second detection seat 2 to generate a height difference, that is, the second detection seat 2 and the horizontal rod 9 move upwards relative to the first detection seat 1, so that the second detection seat 2 is close to the first detection seat 1, the two second rotating rings 8 move forwards along the horizontal rod 9 under the driving of the first detection seat 1, the second rotating rings 8 drive one end, far away from the second rotating rings 8, of the third connecting rod 5 to drive the first connecting shell 14 to rotate clockwise around the axis of the early warning device, one end, far away from the second rotating rings 8, of the fourth connecting rod 6 rotates clockwise around the axis of the early warning device along the first groove section 111 of the second limiting groove 11 of the second connecting shell 15, and an included angle between the first plane structure and the second plane extrusion mechanism is reduced. When the first detection seat 1 and the second detection seat 2 are at the same height, one end of the first connecting rod 3, which is far away from the first rotating ring 7, is located at the joint of the first groove section 111 and the second groove section 112 of the first limiting groove 10 of the first connection shell 14, one end of the second connecting rod 4, which is far away from the first rotating ring 7, is located at the rear end of the first groove section 111 of the first limiting groove 10 on the second connection shell 15, one end of the third connecting rod 5, which is far away from the second rotating ring 8, is located at the front end of the first groove section 111 of the second limiting groove 11 on the first connection shell 14, and one end of the fourth connecting rod 6, which is far away from the second rotating ring 8, is located at the joint of the first groove section 111 and the second groove section 112 of the second limiting groove 11 of the second connection shell 15. When the first detecting base 1 moves downwards relative to the second detecting base 2, that is, the distance between the first detecting base 1 and the second detecting base 2 begins to increase, so that the angle between the first connecting rod 3 and the third connecting rod 5 and the angle between the second connecting rod 4 and the fourth connecting rod 6 begin to increase, in the process, one end of the first connecting rod 3, which is far away from the first rotating ring 7, slides along the second groove section 112 of the first limiting groove 10 of the first connecting shell 14, the first connecting shell 14 rotates counterclockwise around the axis, which extends in the front-back direction and passes through the pre-warning device, under the driving of the third connecting rod 5, one end of the fourth connecting rod 6, which is far away from the second rotating ring 8, slides along the second groove section 112 of the second limiting groove 11 of the second connecting shell 15, the second connecting shell 15 rotates counterclockwise around the axis, which extends in the front-back direction and passes through the pre-warning device, under the driving of the second connecting rod 4, the first rotating part 16 and the second rotating part 17 are brought close to each other, and the electrode sheet 20 is electrically connected to the other buzzer 21 to give an alarm.
