The working principle is as follows: firstly, the staff places the bottom plate 210 at a designated position, then, the staff screws the rotary button 216 again, makes the first threaded rod 222 rotate in the inside of the first threaded groove 223, thereby drives the fixed inserted bar 217 to rotate downwards, makes the one end of the fixed inserted bar 217 insert into the soil in a rotating manner, when the first threaded rod 222 is screwed to be tightest, the fixed inserted bar 217 firmly inserts into the soil, thereby fixedly installing the bottom plate 210 at the designated position, the staff connects a plurality of bottom plates 210 to form a protection groove, and then, the staff places the cable main body 110 between two side plates 211 installed at the top end of the bottom plate 210.

Then, the worker places the first shielding plate 212 at a designated position at the top end of the cable main body 110, and then rotatably inserts the fixing bolt 214 into the screw hole at one side of the side plate 211, and when the fixing bolt 214 is tightened, one end of the fixing bolt 214 is rotatably inserted into the inside of the second screw groove 224, thereby fixedly mounting the first shielding plate 212 at the designated position at the top end of the cable main body 110.

Then, the worker slidably mounts the sliders 220 in the slide grooves 218 of the side plates 211, respectively, and when the bottom end of the first stopper plate 221 is brought into contact with the side of the base plate 210, since one side of the bottom end of the first stopper plate 221 is sixty-degree-inclined, the connecting rod 226 slides in the hole of the partition 225, so that the second stopper plate 227 presses the first spring 228, so that the first spring 228 generates an elastic force, and when the first stopper plate 221 slides to a predetermined position, since the elastic force of the first spring 228 acts on the second stopper plate 227, the connecting rod 226 is reset, thereby driving the first stopper plate 221 to approach the base plate 210, when the connecting rod 226 is reset to a designated position, one end of the first stopper plate 221 is inserted into the inside of the stopper groove 215, therefore, the second protection plate 219 is mounted at the top end of the triangular fixing block 213 and closely attached to the triangular fixing block 213, so that the triangular fixing block 213 protects the fixing bolt 214 and the rotary button 216.

Finally, the staff makes third prevention board 229 cover bottom plate 210 and second protection plate 219 in its bottom with the top of third prevention board 229 installation bottom plate 210, rubber pad 232 and the contact of first protection plate 212 this moment, there is the vehicle or people to walk through when the top of third prevention board 229, rubber pad 232 and first protection plate 212 closely laminate, thereby make second spring 230 receive the extrusion, make second spring 230 produce elasticity, shock attenuation is carried out to the device, then the cable can normally work, can not receive the vehicle extrusion and destroy its surperficial inoxidizing coating.

When the cable needs to be detached, firstly, the worker removes the third protection plate 229, pulls the first limit plate 221 outward to enable the connecting rod 226 to slide in the hole of the partition plate 225, the second limit plate 227 presses the first spring 228 to enable the first spring to generate elastic force, so that one end of the first limit plate 221 is pulled out of the limiting groove 215, then the worker lifts the second protection plate 219 upward to enable the sliding block 220 to slide upward in the sliding groove 218, so that the second protection plate 219 is detached from the two sides of the top end of the bottom plate 210, then the worker unscrews the fixing bolt 214 to enable one end of the fixing bolt 214 to be pulled out of the second threaded groove 224, then removes the first protection plate 212 from the top end of the bottom plate 210, so that the cable body 110 can be removed from the top end of the bottom plate 210, then screws the rotary button 216 reversely to enable the first threaded rod 222 to rotate reversely, thereby causing the stationary bayonet 217 to rotate upward and be pulled out of the soil, and then the worker can move the base plate 210 elsewhere.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
