the wire passing guide sleeve (21) is provided with a plurality of hard intermittent clamping shells (211) which are distributed at equal intervals, and the connecting end tightening unit (32) is connected to the inner side of the hard intermittent clamping shells (211) in a clamping mode and keeps a pressing state with the power distribution passing point grounding lead (2).
2. A power distribution protection device for gardens as claimed in claim 1, wherein: one side of the landscape interval isolation part (41) is hinged with a grounding end sealing module (44), and the grounding end sealing module (44) is used for sealing the power distribution crossing point sectional arrangement assembly (4) and the expansion separation response group (5) embedded in the waterproof mode behind the inner side of the landscape interval isolation part (41).
3. The method of using a power distribution protection device for gardens as claimed in claim 2, wherein: the method comprises the following steps:
step S1, a wire guide sleeve (21) is guided to cross a landscape by a grounding wire end guide group (13), the assembly positions of the power distribution crossing point sectional arrangement components (4) are selected according to required continuous grounding points, and the power distribution crossing point sectional arrangement components (4) are sequentially pushed to reach preset grounding points;
s2, selecting a standard point embedded seat (31) to be sent in through the inner side of a landscape interval isolation part (41), enabling a grounding protection pin (34) to slide towards an interface end adaptive locking part (42) until the grounding protection pin (34) penetrates through the bottom of an embedded point filling part (43) to extend to a grounding surface, enabling a connection end tightening unit (32) to reach the inner side of a hard intermittent clamping shell (211) after the standard point embedded seat (31) is aligned with the landscape interval isolation part (41) in a sliding mode, enabling the inner side and the outer side of the connection end tightening unit (32) to be subjected to mutual extrusion force of a power distribution point grounding lead (2) and the hard intermittent clamping shell (211), and realizing high-fit clamping connection of a grounding passage;
and S3, after the standard point embedding seat (31) is assembled and embedded with the landscape interval isolation part (41), the single-contact in-place signal receiving unit (51) returns a grounding depth in-place signal of the grounding protection pin (34) to the in-place reaction end (52), so that the in-place reaction end (52) feeds back the current continuous grounding state to the grounding coverage response terminal (12) in real time, positions the position of the implemented continuous grounding point, and realizes the monitoring of the continuity of the grounding state.
