After rotation, the inclined side of the right edge connecting post 202 and the inclined side of the left edge connecting post 201 fit together.

[0056] The number of left edge connecting holes 207 and the number of right edge connecting holes 208 can be determined as needed. Preferably, there are multiple left edge connecting holes 207 and multiple right edge connecting holes 208, and the multiple left edge connecting holes 207 and the multiple right edge connecting holes 208 are arranged horizontally spaced from each other. Please refer to [link to relevant documentation]. Figure 5 As shown, in a specific embodiment of this utility model, there are two left edge connecting holes 207 and two right edge connecting holes 208. One of the left edge connecting holes 207 is located to the right front of the other left edge connecting hole 207, and one of the right edge connecting holes 208 is located to the left front of the other right edge connecting hole 208.

[0057] In use, taking a vertically arranged wall along the left and right directions as an example, the wall has openings along the front and back directions. When edge protection of the wall openings is required, the main protective module 1 of this utility model is placed in front of the wall openings. The left edge fixing post 101 is moved to the left and the right edge fixing post 103 is moved to the right, so that the first left and right telescopic protective net 104 and the second left and right telescopic protective net 105 extend left and right until the left edge fixing post 101 abuts against the left side of the wall and the right edge fixing post 103 abuts against the right side of the wall. Bolts, for example, 1 Bolt No. 2 is screwed into the left edge horizontal fixing hole 111 and the left wall, and the right edge horizontal fixing hole and the right wall, respectively, thereby fixing the left edge fixing post 101 to the left wall and the right edge fixing post 103 to the right wall. Bolts such as No. 12 are screwed into the left edge vertical fixing hole 109 and the ground, the middle vertical fixing hole 110 and the ground, and the right edge vertical fixing hole and the ground, respectively, thereby fixing the left edge fixing base plate 106, the middle fixing base plate 107 and the right edge fixing base plate 108 to the ground.

[0058] If the wall opening is too long in the left-right direction, and one main protective module 1 is insufficient, multiple main protective modules 1 can be used. Two adjacent main protective modules 1 are connected by an edge connecting module 2. Specifically, the edge connecting module 2 is placed between two adjacent main protective modules 1, so that the left insertion rod 205 and the right insertion rod 206 are aligned with the right insertion hole of the left main protective module 1 and the left insertion hole of the right main protective module 1, respectively. Then, the left main protective module 1 is moved to the right and the right main protective module 1 is moved to the left until the left insertion rod 205 and the right insertion rod 206 are inserted into the right insertion hole of the left main protective module 1 and the left insertion hole of the right main protective module 1, respectively, in the left-right direction. In the hole, the right edge fixing base plate 108 of the left main protective module 1 abuts against the left edge connecting plate 203, and the left edge fixing base plate 106 of the right main protective module 1 abuts against the right edge connecting plate 204. Then, similar to the above, bolts are used to fix the leftmost left edge fixing post 101 to the left wall and the rightmost right edge fixing post 103 to the right wall. Bolts are used to fix the left edge fixing base plate 106, the middle fixing base plate 107 and the right edge fixing base plate 108 to the ground. Bolts are also screwed into the left edge connecting hole 207 and the ground and the right edge connecting hole 208 and the ground, thereby fixing the left edge connecting plate 203 and the right edge connecting plate 204 to the ground.

[0059] If the floor opening is set vertically in the floor slab, and there is a bend in the floor opening, the right edge connecting column 202 of the edge connecting module 2 can be rotated horizontally relative to the left edge connecting column 201 to generate a corner, so as to adapt to the edge protection at the bend of the opening.

[0060] Therefore, this utility model provides a multi-purpose edge protection device. The main protection module can be used independently, and the main protection modules can be quickly connected to each other through edge connecting modules. It can be fixed to the wall and the ground with bolts, meeting both standardized and non-standardized protection needs. It is easy and quick to install and disassemble, and can be reused. It can adapt to edge protection needs of various sizes and shapes and is easy to install, requiring only bolt fixing. It can effectively solve edge protection needs of different sizes, improve safety production efficiency, and reduce safety production accidents such as falls and object strikes.

[0061] In summary, the multi-purpose edge protection device of this utility model can adapt to the edge protection needs of various sizes and shapes, is easy to install, flexible to use, ingeniously designed, simple in structure, easy to manufacture, and has low manufacturing cost, making it suitable for large-scale promotion and application.

[0062] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
