The left side of the stabilizing block 902 is fixedly connected with a spring 903, and the left side of the spring 903 is fixedly connected to the inner cavity of the limiting shell 901.
[0024] With the above solution, by providing the limiting device 9 , when the rotating plate 4 is rotated to a suitable angle, the limiting device 9 has a limiting effect on the position of the rotating plate 4 .
[0025] refer to Figure 3 The top of the limiting shell 901 is fixedly connected to an extrusion block 10, and the side of the extension plate 3 close to the limiting shell 901 is movably connected to an extrusion rotating shell 11 used in conjunction with the extrusion block 10 through a rotating shaft, and the inner cavity of the extrusion rotating shell 11 contacts the surface of the extrusion block 10.
[0026] The above solution is adopted: by providing the extrusion block 10 and the extrusion rotating shell 11, when the extrusion rotating shell 11 rotates, an extrusion force can be generated on the extrusion block 10, and the extrusion block 10 subjected to the extrusion force can drive the limiting shell 901 to move.
[0027] refer to Figure 2 The inner cavity of the extrusion rotating shell 11 is movably connected to an extrusion rod 12 , and opposite sides of the two extrusion rods 12 are fixedly connected to the surface of the control frame 8 .
[0028] The above solution is adopted: by setting the extrusion rod 12, when the control frame 8 moves, the extrusion rod 12 can be driven to move along the extrusion rotating shell 11, and the extrusion force generated by the extrusion rod 12 on the extrusion rotating shell 11 can drive the extrusion rotating shell 11 to move along the surface of the extrusion block 10.
[0029] refer to Figure 3 Two blocks 13 are fixedly connected to the surface of the extrusion rod 12 , and opposite sides of the two blocks 13 are in contact with the surface of the extrusion rotating shell 11 .
[0030] By adopting the above solution, by setting the block 13 , when the extrusion rod 12 moves, the two blocks 13 can be driven to move simultaneously along the surface of the extrusion rotating shell 11 . The setting of the block 13 has a limiting effect on the moving position of the extrusion rod 12 .

[0034] The above solution is adopted: by setting the slider 16 and the slide groove 17, when the extension plate 3 moves, the slider 16 can be driven to move along the inner cavity of the slide groove 17. The cooperation of the slider 16 and the slide groove 17 has a limiting effect on the moving position of the extension plate 3.
[0035] The working principle of this utility model:
[0036] During use, when it is necessary to expand the use area of the workbench 1 for power amplifier design, first pull the extension plate 3 backward to drive the extension plate 3 to move backward along the inner cavity of the extension slot 2. When the extension plate 3 moves, it will drive the slider 16 to move along the inner cavity of the slide slot 17. When the extension plate 3 moves, it will drive the rotating plate 4 to move backward. When the rotating plate 4 completely moves out of the inner cavity of the extension slot 2, pull the control frame 8 to the opposite side of the two control frames 8. When the control frame 8 moves, it will drive the extrusion rod 12 to move along the inner cavity of the extrusion rotating shell 11, and at the same time drive the two card blocks 13 to move along the surface of the extrusion rotating shell 11. The extrusion rotating shell 11 subjected to the extrusion force will rotate along the surface of the extrusion block 10 through the rotating shaft. When the extrusion block 10 is subjected to the extrusion force of the extrusion rotating shell 11 When the limit shell 901 moves, it will drive the limit shell 901 to move along the surface of the stabilizing block 902. The force generated when the limit shell 901 moves causes the spring 903 to undergo elastic deformation. When the limit shell 901 is out of contact with the inner cavity of the first limit groove 14, the rotating shell 6 can be rotated. The rotation of the rotating shell 6 drives the rotating plate 4 to rotate. When the rotating plate 4 rotates to ninety degrees, the control frame 8 is released. The restoring force generated by the spring 903 restoring its shape will drive the limit shell 901 to be stuck into the inner cavity of the second limit groove 15. The coordinated use of the second limit groove 15 and the limit shell 901 has a limiting effect on the position of the rotating plate 4. The extension plate 3 increases the use area of the workbench 1, and the rotating plate 4 has the function of posting design drawings for easy observation and reference. At this time, the use area of the workbench 1 for power amplifier design is expanded.
[0037] To sum up: the power amplifier design workbench, by setting the limit device 9, the limit shell 901, the stabilizing block 902, the spring 903 and the extrusion block 10 for coordinated use, solves the problem that the existing power amplifier design workbench is an auxiliary table used for the needs of power amplifier design work. When in use, designers can place design materials, drawings, models, etc. on the workbench to facilitate the design work. The existing workbench surface is a fixed area that cannot be adjusted, but the design materials are relatively complicated, and the workbench is prone to insufficient use area. In addition, drawings need to be posted for observation or reference during design, but the use area of the existing power amplifier design workbench has no components for expanding the problem.
