The two resilient members 62 are mounted around two ends of the inner tube 331 and contact the two ends of the outer tube 332, respectively. When the second positioning assembly 60 is at a fastened status, the handle 61 is rotated to be fastened, such that the handle 61 pushes against the second support rack 30, and the second support rack 30 presses the first support rack 20, while the resilient member 62 is pressed by the outer tube 332 at the location of the pivotal combination between the second support rack 30 and the first support rack 20. Therefore, the angle of the second support rack 30 swaying against the first support rack 20 is fixed. When the second positioning assembly 60 is at a loosened status, the handle 61 is rotated to be loosened, such that the second support rack 30 laterally moves against the first support rack 20 due to the resilient force of the resilient member 62. Therefore, the angle of the second support rack 30 swaying against the first support rack 20 is able to be adjusted.

In addition, the second positioning assembly 60 comprises a second pillar 63 and a plurality of second grooves 64. The second pillar 63 is disposed on the second support rack 30. The second grooves 64 are disposed on the first support rack 20 in an equiangular arrangement, such that the second support rack 30 and the first support rack 20 are allowed to be engaged. When the second positioning assembly 60 is at the loosened status, the second support rack 30 is allowed to sway to a targeted angle against the first support rack 20, while the second pillar 63 is in alignment with one of the second grooves 64. Subsequently, the handle 61 is rotated to be fastened again, such that the handle 61 pushes against the second support rack 30, and the second support rack 30 presses against the first support rack 20. Therefore, the second pillar 63 is engaged in the second groove 64 for adjusting and fixing the angle included by the second support rack 30 and the first support rack 20.

Referring to FIG. 3 and FIG. 8, based on different user demands, when the user needs to adjust the inclination angle of the table board 40, the handle 61 is rotated to be loosened. Subsequently, if the inclination angle of the table board 40 is to be increased, and the second support rack 30 sways away from the first support rack 20; if the inclination angle of the table board 40 is to be decreased, the second support rack 30 sways toward the first support rack 20. Upon the angle between the second support rack 30 and the first support rack 20 reaching a targeted degree, the handle 61 is rotated to be fastened again. Therefore, the inclination angle of the table board 40 is adjusted and fixed.

Referring to FIG. 3 and FIG. 9, when the user needs to adjust the height of the table board 40 against the ground, the handle 51 is rotated to be loosened. When the height of the table board 40 is to be increased, the first support rack 20 sways away from the foot 10; when the height of the table board 40 is to be decreased, the first support rack 20 sways toward the foot 10. Upon the angle between the first support rack 20 and the foot 10 reaching a targeted degree, the handle 51 is rotated to be fastened again. Therefore, the height of the table board 40 against the ground is adjusted and fixed.
