[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 The extended folding computer desk shown is characterized by comprising: a base plate 1; a lower platform shell 2 fixed above the front side of the base plate 1; an upper platform shell 3 movably mounted on the lower platform shell 2; handrails 31 fixed on the left and right sides above the upper platform shell 3; a tabletop 9 fixed above the upper platform shell 3; a connector 4 provided on the lower platform shell 2 and the upper platform shell 3; locking parts 5 provided on the left and right sides of the upper platform shell 3 to lock the upper platform shell 3 onto the lower platform shell 2; a driving part 6 provided above the upper platform shell 3 to drive the locking parts 5; a microphone part 7 that can be placed at multiple angles on the front side of the tabletop 9; and a placement part 8 provided on the tabletop 9.

[0020] In the above-described extendable folding computer desk, when in use, the user pulls the drive unit 6, causing the drive unit 6 to unlock the locking unit 5. At this time, the lower shell 2 and the upper shell 3 separate from each other. The user pulls the upper shell 3 upward to a suitable height. When in use, the user can place the laptop on the placement unit 8. The placement unit 8 can adjust the display angle of the computer. At the same time, the user can speak through the microphone unit 7. Compared with the prior art, the computer desk can be adjusted according to the user's actual usage height.

[0021] like Figure 4 As shown, in some embodiments of this utility model, the insertion part 4 includes guide rails 41 symmetrically arranged on the front side of the inner wall of the lower platform shell 2, and guide grooves 42 symmetrically arranged on the front side of the upper platform shell 3. Each guide groove 42 is movably inserted into the adjacent guide rail 41. When the upper platform shell 3 moves, the upper platform shell 3 moves upward along the guide rail 41 through the guide grooves 42, so that the upper platform shell 3 moves the platform 9 to a suitable height.

[0022] like Figures 2 to 4As shown, in some embodiments of this utility model, the locking part 5 includes plug-in rods 51 symmetrically fixed to the inner wall of the upper platform shell 3. A movable plate 52 is provided on one side of each plug-in rod 51, and a plug-in groove 53 is provided on each movable plate 52. Each plug-in groove 53 is movably inserted into an adjacent plug-in rod 51. Push blocks 54 are symmetrically fixed below each plug-in rod 51. Through holes 55 are symmetrically fixed on both the left and right sides of the inner wall of the upper platform shell 3. A rail 56 is fixed above each through hole 55, and a locking slider 57 is movably inserted into each rail 56. A locking slider 57 is provided below each locking slider 57. The inclined block 58 has multiple slots 59 spaced apart on the left and right sides of the inner wall of the lower platform shell 2. The driving part 6 drives the moving plate 52 to move upward, so that the moving plate 52 moves along the insertion rod 51 through the insertion slot 53. When the moving plate 52 moves, it contacts the inclined block 58 through the inclined surface on the push block 54, so that the inclined block 58 moves the locking slider 57 along the insertion rail 56, so that the locking slider 57 moves in the through hole 55 and separates from the slot 59. At this time, the user moves the upper platform shell 3 to a suitable height, and then the driving part 6 resets the moving plate 52 and the locking slider 57, so that the locking slider 57 is inserted into the slot 59.

[0023] like Figures 2 to 4 As shown, in some embodiments of this utility model, the driving unit 6 includes handles 61 fixed above each of the movable plates 52, through slots 62 are provided above the lower housing 2 and the upper housing 3, and each handle 61 is disposed in an adjacent through slot 62. Multiple first tension springs 63 are fixedly connected between the lower part of each movable plate 52 and the lower part of the upper housing 3. An extension plate 64 is fixed to one side of each snap-fit ​​slider 57. Guide posts 65 are symmetrically fixed to the inner wall below the upper housing 3, and each extension plate 64 is movably sleeved on an adjacent guide post 65. A second tension spring 66 is wound around each of the guide posts 65. When the user pulls the handle 61, the handle 61 moves upward along the through groove 62, causing the handle 61 to move the moving plate 52. After the upper housing 3 is adjusted to a suitable position, the user releases the handle 61. At this time, the first tension spring 63 drives the moving plate 52 to reset. At the same time, the second tension spring 66 applies a pushing force to the locking slider 57. At this time, the locking slider 57 moves along the insertion rail 56. Simultaneously, the locking slider 57 moves along the guide post 65 through the extension plate 64, so that the locking slider 57 is inserted into the locking groove 59.

[0024] like Figure 2 and 3As shown, in some embodiments of this utility model, the microphone part 7 includes hinge ears 71 symmetrically fixed on the tabletop 9, and a microphone 72 is movably hinged between each of the hinge ears 71. Multiple snap-fit ​​protrusions 73 are fixed at the hinge ends of the microphone 72, and an arc-shaped snap-fit ​​groove 74 is provided on one of the hinge ears 71. When the user operates the microphone 72, the microphone 72 can be swung to a suitable position. At this time, the multiple snap-fit ​​protrusions 73 fixed at the hinge ends of the microphone 72 can be locked in the arc-shaped snap-fit ​​groove 74, thereby locking the swing angle of the microphone 72.

[0025] like Figure 2 and 3 As shown, in some embodiments of this utility model, the placement part 8 includes a placement groove 81 provided on the tabletop 9, a placement plate 82 is movably hinged in the placement groove 81, clearance positions 83 are provided on the left and right sides of the placement plate 82, a connecting rod 84 is movably hinged to the rear side of each clearance position 83, and a pressing block 85 is movably hinged to the end of each connecting rod 84. Multiple top grooves 86 are provided at intervals on the tabletop 9 on the left and right sides of the placement groove 81. When the user places a laptop on the placement plate 82, the protrusion on the placement plate 82 blocks the laptop. At this time, the user can flip the placement plate 82 backward to a suitable angle, and the connecting rod 84 swings accordingly. The pressing block 85 at the end of the connecting rod 84 presses against the adjacent top groove 86, thereby changing the angle of the placement plate 82.

[0026] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
