A spring 95 is fixedly connected to the bottom of the trapezoidal block 94. A push rod 96 is fixedly connected to the top of the trapezoidal block 94. The top of the push rod 96 passes through the top of the fixed block 7. The four corners inside the fixed block 7 are fixedly connected with sliding rods 97. The surface of the sliding rod 97 is sleeved with a tension spring 98. The surface of the tension spring 98 is fixedly connected to the inner wall of the moving plate 92 and the fixed block 7.

[0022] As a technical optimization solution of the utility model, by setting a fixing mechanism 9, the fixed frame 5 and the adjustable surrounding rod group 4 can be fixed, so as to avoid the adjustable surrounding rod group 4 being unable to be positioned, resulting in the loosening of the adjustable surrounding rod group 4, thereby improving the convenience of using the fixed frame 5 and the adjustable surrounding rod group 4.

[0023] refer to Figure 3 The top of the push rod 96 is fixedly connected with a push block 10, and the push block 10 is located on the top of the fixed block 7.

[0024] As a technical optimization solution of the present invention, by providing the push block 10 , the contact area between the user and the push rod 96 can be increased, thereby avoiding a small contact area between the push rod 96 and the user and improving the pushing efficiency of the push rod 96 .

[0025] refer to Figure 3 Stabilizing rods 11 are provided on the front and rear sides of the trapezoidal block 94 , and the surface of the stabilizing rod 11 is fixedly connected to the inner wall of the fixing block 7 .

[0026] As a technical optimization solution of the utility model, by setting a stabilizing rod 11, the sliding of the trapezoidal block 94 can be stabilized to prevent the trapezoidal block 94 from shaking during the sliding movement, causing the trapezoidal block 94 to loosen, thereby improving the sliding stability of the trapezoidal block 94.

[0027] refer to Figure 3Limiting blocks 12 are provided on the front and rear sides of the top of the trapezoidal block 94 , and the inner sides of the limiting blocks 12 are fixedly connected to the inner walls of the fixing blocks 7 .

[0028] As a technical optimization solution of the utility model, by setting the limit block 12, the trapezoidal block 94 can be limited to avoid excessive movement of the trapezoidal block 94, which causes the trapezoidal block 94 to separate from the pulley 93, thereby improving the working stability of the trapezoidal block 94.

[0029] refer to Figure 3 The outer side of the positioning pin 91 is fixedly connected with a guide block 13 , and the guide block 13 is located inside the card slot 8 .

[0032] As a technical optimization solution of the utility model, by setting the round block 14, the fixed block 7 can be limited to avoid excessive movement of the fixed block 7, which causes the fixed block 7 to separate from the fixed rod 6, thereby improving the working stability of the fixed block 7.

[0033] The working principle and use process of the utility model are as follows: when in use, the figure shows that the adjustable fence group 4 and the fixed fence 5 are in a fixed state. When the height of the fixed fence 5 needs to be adjusted, the push rod 96 is pressed down, and the push rod 96 drives the trapezoidal block 94 to move downward, and the trapezoidal block 94 compresses the spring 95, and the trapezoidal block 94 loses support for the pulley 93. The pulling force of the tension spring 98 drives the movable plate 92 and the positioning pin 91 to move to the side away from the slot 8, and the positioning pin 91 withdraws from the inside of the slot 8, and the fixed rod 6 and the fixed block 7 lose fixation, and the fixed fence 5 is moved upward, and the fixed fence 5 drives the fixed block 7 to move upward on the surface of the fixed rod 6, and the adjustable fence group 4 stretches the adjustable fence group 4. When the fixed fence 5 rises to a suitable height, the push rod 96 is released, and the positioning pin 91 returns to its original position, thereby having the advantage of convenient adjustment of the fence height.

[0034] In summary: the adjustable scaffold for construction projects, through the coordinated use of the base plate 1, the telescopic rod 2, the lifting plate 3, the adjustable fence group 4, the fixed fence 5, the fixed rod 6, the fixed block 7, the slot 8 and the fixing mechanism 9, solves the problem that the guardrail is in a fixed state as a whole, the height of the guardrail is also fixed, and the height of the guardrail cannot be adjusted according to the height of the user. When the user is too tall, the fixed height fence cannot meet the user's needs, and the low fence cannot protect the taller user, which reduces the safety of the scaffold.
