[0023] As a technical optimization solution of the utility model, by setting the clamping assembly 7, the clamping spring 72 inside the fixed tube 71 can drive the clamping plate 73 to move downward through its own elastic force, so that the clamping plate 73 can drive the positioning rod 5 to move downward after moving downward.

[0024] refer to Figure 3 The extension assembly 8 includes an extension groove 81 , which is opened at the bottom of the splicing frame 3 . An extension block 82 is movably connected inside the extension groove 81 , and two splicing frames 3 can be spliced ​​and used through the extension block 82 .

[0025] As a technical optimization solution of the utility model, by setting an extension component 8, the two splicing frames 3 can be inserted into the extension groove 81 through the extension block 82 at the bottom for splicing, thereby facilitating the user to assemble and use the two splicing frames 3, increasing the convenience of the splicing frames 3 when in use.

[0026] refer to Figure 2 The top of the clamping plate 73 is fixedly connected with a pull rod 9 , and the top of the pull rod 9 passes through the top of the fixed tube 71 and is movably connected with the fixed tube 71 .

[0027] As a technical optimization solution of the utility model, by setting the pull rod 9, the use of the pull rod 9 can facilitate the user to pull the clamping plate 73 upwards, so that the upward moving clamping plate 73 drives the positioning rod 5 to move upward and separate from the positioning hole 6, thereby facilitating the user to disassemble the splicing frame 3 and the circuit board 1.

[0028] refer to Figure 2 A holding limit ball 10 is fixedly connected to the top of the pull rod 9, and the holding limit ball 10 is movably connected to the fixed tube 71.

[0032] The working principle and use process of the utility model are as follows: when it is necessary to splice two circuit boards 1, two splicing frames 3 are prepared, and one corner of the circuit board 1 is inserted into the splicing frame 3 through the splicing groove 2. As the splicing groove 2 on the circuit board 1 is inserted into the splicing frame 3, the positioning rod 5 inside the movable groove 4 will be pushed upward. As the splicing groove 2 and the splicing frame 3 are completely fitted together, the positioning hole 6 on the circuit board 1 will be aligned with the positioning rod 5. At the same time, the clamping spring 72 inside the fixed cylinder 71 will drive the clamping plate 73 to move downward through its own elastic force, so that the clamping plate 73 will push the positioning rod 5 downward after moving downward, so that the positioning rod 5 is inserted into the positioning hole 6, achieving the effect of convenient assembly. At the same time, the two splicing frames 3 can be spliced ​​with the extension groove 81 at the bottom of the same structure in conjunction with the extension fastener, which is convenient for users to splice four circuit boards 1.

[0033] To sum up: this circuit board panelization structure, by setting the positioning rod 5 and the positioning hole 6, allows the circuit board 1 to be inserted into the splicing frame 3 through the splicing groove 2, and the positioning rod 5 will be inserted into the positioning hole 6 under the action of the tightening component 7, which solves the problem of splicing adjacent circuit boards by bolts during use. As the number of circuit boards increases, the number of bolts used will also increase accordingly, resulting in a more cumbersome problem when splicing circuit boards.
