The mountain slope geographic information mapping device of claim 1, wherein: the bottom of supporting platform (1) sets firmly magnet (44), has seted up the centre bore in magnet (44), and centre bore and square groove (21) intercommunication, lifter (22) from lower to upper run through centre bore and square groove (21) setting in order, the welding has iron plate (45) that are located magnet (44) under lifter (22).

10. The use method of the mountain slope geographic information mapping device according to any one of claims 1-9, wherein the method comprises the following steps: it comprises the following steps:

s1, the operator carries the whole surveying and mapping device to the slope of the mountain through the hanging ring (43), and selects one side close to the tree (48);

s2, fixing the first fulcrum, screwing out the nut A (15) by an operator, moving the locking block II (8) backwards to ensure that the locking block II (8) is separated from the locking block I (7), and sleeving the region formed by the arc-shaped groove I (9) and the arc-shaped groove II (14) on the trunk of the selected tree (48) by the operator after separation; then the nut A (15) is screwed down again, the locking block II (8) moves towards the locking block I (7) under the threaded connection force, and after the nut A (15) cannot be screwed down again, the trunk of a tree (48) is held between the arc-shaped groove I (9) and the arc-shaped groove II (14), so that the first fulcrum is fixed;

s3, fixing a second fulcrum, rotating the case (16) relative to the supporting platform (1) by an operator, keeping the case (16) stationary after a drill bit (20) of the grounding mechanism (4) faces a slope, then opening the motor D (19) and the motor B (28) by the operator, driving the screw rod B (29) to rotate by the motor B (28), driving the nut B (30) to move downwards along the screw rod B (29), driving the supporting plate (18) and a surveying and mapping instrument (46) thereon to move downwards by the nut B (30), driving the drill bit (20) to rotate by the motor D (19), and drilling the drill bit (20) into a high stratum under two combined motions, so that the fixing of the second fulcrum is realized, and the whole surveying and mapping device is fixed;

s4, jacking shrubs, firstly opening a motor E (41) by an operator, transmitting torque of the motor E (41) to an output shaft of a speed reducer (42) after the torque is reduced by the speed reducer (42), driving an inclined plate (24) to rotate by the output shaft, then lifting up a lifting rod (22) by the operator to enable an iron plate (45) to move towards a magnet (44), driving a screw nut pair C and the inclined plate (24) to upwards penetrate through a through groove (2) by the lifting rod (22) in the upward movement process, rotating and linearly moving the inclined plate (24) upwards, and jacking out the shrubs covered above a surveying instrument (46) by the inclined plate (24); when the iron plate (45) contacts the magnet (44), the lifting rod (22) can be loosened; thereby effectively preventing the surveying instrument from being shielded by shrubs and ensuring the smooth surveying and mapping;

s5, an operator can survey and draw the mountain through the surveying and drawing instrument (46), in the surveying and drawing process, if the height of the surveying and drawing instrument (46) is to be adjusted, the motor C (32) is turned on at the moment, the motor C (32) drives the screw rod C (33) to rotate, the nut C (34) moves upwards along the screw rod C (33), so that the bearing table (25) and the surveying and drawing instrument (46) on the bearing table are driven to move upwards, the surveying and drawing instrument (46) penetrates through the through groove (2) and moves above the supporting platform (1), and the motor C (32) is turned off after the motor moves to a proper position, so that the height of the surveying and drawing instrument is adjusted; if the surveying and mapping direction of the surveying and mapping instrument (46) needs to be adjusted, the nut D (40) can be unscrewed, then the disc (36) is rotated around the axis of the fixed shaft (26), the adjusting screw (39) moves in the arc-shaped hole (38) relative to the disc (36), the surveying and mapping instrument (46) is driven to rotate when the disc (36) rotates, and the nut D (40) is screwed after the adjustment is in place, so that the direction of the surveying and mapping instrument is adjusted.
