[0028] Working principle: refer to the descriptionFigure 6 As shown, first, the device as a whole needs to be positioned at the designated placement position, and only the device as a whole needs to be adjusted to the appropriate placement position, and then the ground nail 603 is used to penetrate the installation slot 602 into the corresponding position in the stratum, thereby completing the positioning and installation process of the device as a whole.

[0029] Referring to the drawings Figure 1 -attached drawings Figure 4 As shown, when the guardrail leg 2 of the edge protection fence needs to be installed into the fixed base body 1 at the corresponding position, first, the fixed base body 1 needs to be pushed into the containing cavity of the fixed base body 1 in the vertically downward direction. When the guardrail leg 2 contacts the abutting block 402 during the downward movement, the bottom end of the guardrail leg 2 is provided with a chamfer, and the top end outer wall of the abutting block 402 is correspondingly provided with an arc-shaped structure, and the abutting block 402 slides into the placement slot 401 under the abutting action of the guardrail leg 2. When the abutting block 402 is completely retracted into the placement slot 401, the guardrail leg 2 can be normally inserted into the inside of the fixed base body 1, and the movement trajectory of the abutting block 402 also synchronously squeezes the abutting spring 406 to retract into the cylindrical slot 405. At this time, the abutting spring 406 is in a retracted state, and when the guardrail leg 2 moves to the bottom end of the fixed base body 1, the abutting block 402 is automatically ejected by the reaction force generated by the abutting spring 406, and the abutting block 402 is clamped into the inside of the abutting block slot 409, and the abutting block 402 and the abutting block slot 409 are tightly positioned in the inside of the fixed base body 1.

[0030] When the guardrail leg 2 needs to be taken out from the inside of the fixed base body 1, first, the two sets of limiting handles 408 need to be pulled outwards at the same time, and then the abutting block 402 is completely pulled into the inside of the placement slot 401 by pulling the rod 407, so that the abutting block 402 and the abutting block slot 409 lose the clamping effect, and then the guardrail leg 2 can be directly pulled out from the inside of the fixed base body 1 along the vertical direction.

[0031] Referring to the drawings Figure 4 When the abutting block 402 slides in the abutting block slot 409, the limiting block 403 and the limiting sliding slot 404 are automatically driven to slide in the inside, and the limiting block 403 and the limiting sliding slot 404 are provided to limit the movement of the abutting block 402, and at least part of the block body is located in the abutting block slot 409, thereby avoiding the phenomenon that the abutting block 402 is difficult to reset after being completely pulled out of the abutting block slot 409.

[0032] Referring to the drawings Figure 5 - the drawings Figure 6 , the need for corresponding adjustment of the fixed base body 1 in the installation position of the guide rail 3 is affected by the distance between the guardrail bodies, at this time the first need is to unscrew the fastening bolt 506 from the inside of the first threaded groove 504, and then the positioning frame 503 changes from the locked state to the active state, and then the fixed base body 1 can be adjusted according to the installation position requirement of the guardrail The position on the guide rail 3, when the fixed base body 1 moves, it will automatically drive the positioning T-shaped strip 501 and the inside of the positioning T-shaped groove 502 to slide, and then when the fixed base body 1 moves to the appropriate support position, at this time the fastening bolt 506 is screwed through the first threaded groove 504 to the bottom end of the second threaded groove 505 corresponding to the position, the repositioning process of the positioning frame 503 can be completed;

[0033] The above is the working process of the entire device, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0034] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
