[0018] The top end inside the first anti-pressure protrusion 3, the second anti-pressure protrusion 4 and the third anti-pressure protrusion 5 and the upper surface of the top cover main body 1 are provided with a supporting assembly, the supporting assembly increases the structural strength of the first anti-pressure protrusion 3, the second anti-pressure protrusion 4 and the third anti-pressure protrusion 5, supports the top surface, makes the first anti-pressure protrusion 3, the second anti-pressure protrusion 4 and the third anti-pressure protrusion 5 not easy to produce deformation and collapse when being pressed, makes the structure more stable under external pressure, and makes the supporting resistance effect of the first anti-pressure protrusion 3, the second anti-pressure protrusion 4 and the third anti-pressure protrusion 5 better.
[0019] The support assembly comprises two reinforcing plates 801 arranged symmetrically inside the first compression-resistant protrusion 3, the second compression-resistant protrusion 4 and the third compression-resistant protrusion 5 in an isosceles trapezoidal structure, and a horizontal connecting plate 802 arranged between the two reinforcing plates 801.
