[0018] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0019] Example 1

[0020] like Figures 1 to 5 The scaffolding accessory fastening device of the utility model comprises a fixing block 3, two groups of support columns 4 and two groups of clamping mechanisms. The two groups of support columns 4 are respectively fixedly installed on the upper and lower parts of the fixing block 3. The two groups of clamping mechanisms are respectively installed on the upper and lower parts of the fixing block 3. The clamping mechanisms have the functions of clamping and fixing. The two groups of support columns 4 are coaxial. When the steel pipe A1 and the steel pipe B2 need to be fixed up and down when building the scaffold, the steel pipe A1 and the steel pipe B2 are respectively located on the upper and lower sides of the fixing block 3, and then the support columns 4 of the upper and lower parts of the steel pipe A1 are respectively inserted into the steel pipe B2. Among the steel pipes A1, the support column 4 and the inner side walls of the steel pipes A1 and B2 are interference fit, and then the steel pipes B2 and A1 can be clamped and fixed respectively by the clamping mechanisms of the upper and lower parts of the fixing block 3; when connecting the steel pipes B2 and A1, not only the steel pipes A1 and B2 are clamped and fixed by the clamping mechanisms, but also two groups of support columns 4 are respectively inserted into the inner holes of the steel pipes A1 and B2, thereby improving the strength of the connection between the steel pipes A1 and B2, making the connection more stable, not easy to shake, and having high safety and reliability.

[0021] like Figure 1 and Figure 2 The clamping mechanism includes two groups of clamping plates 5 and a moving mechanism. The two groups of clamping plates 5 are installed on the fixed block 3 through the moving mechanism. The moving mechanism is used to move the two groups of clamping plates 5. When clamping and fixing the steel pipe, the steel pipe is placed on the fixed block 3, and then the two groups of clamping plates 5 are moved close to each other through the moving mechanism until the two groups of clamping plates 5 clamp and fix the steel pipe. This facilitates the clamping and fixing of the steel pipe.

[0022] like Figure 2 The moving mechanism includes a driving mechanism, a vertical plate 6 and a slide rail 7. The vertical plate 6 is fixedly installed on the fixed block 3, and the slide rail 7 is fixedly installed on the vertical plate 6. The two sets of clamps 5 are slidably installed on the slide rail 7 forward and backward. The driving mechanism is used to drive the two sets of clamps 5 to move; when the steel pipe is clamped and fixed by the two sets of clamps 5, when the support column 4 is inserted into the steel pipe, the two sets of clamps 5 are driven by the driving mechanism to approach each other until the two sets of clamps 5 clamp and fix the steel pipe.

[0023] like Figure 1 The driving mechanism includes a fixed plate 8 and a screw 9. The fixed plate 8 is fixedly mounted on the fixed block 3, and the screw 9 is rotatably mounted on the fixed plate 8. The front and rear parts of the screw 9 are respectively provided with external threads with opposite rotation directions. The two groups of clamping plates 5 are respectively screwed with the front and rear parts of the screw 9. When clamping the steel pipe, first place the steel pipe between the two groups of clamping plates 5, and then rotate the screw 9. The rotating screw 9 drives the two groups of clamping plates 5 to approach each other until the two groups of clamping plates 5 clamp and fix the steel pipe, which facilitates the fixation of the steel pipe.

[0024] like Figure 2 A mounting plate 11 is provided at the lower end of the support column 4, and the mounting plate 11 is mounted on the fixing block 3 by bolts; through the above arrangement, the disassembly and replacement of the support column 4 on the fixing block 3 is facilitated, thereby improving convenience.
