[0033] Optionally, in some embodiments of this utility model, the waterproof pad 14 is interference-fitted into the bottom of the annular groove 12. This can be understood as the waterproof pad 14 utilizing its deformable properties to allow its two sides to abut against the two sides of the annular groove 12, thus securing the waterproof pad 14 firmly within the annular groove 12. The waterproof pad 14 can be a rubber pad.

[0034] Optionally, in some embodiments of this utility model, the waterproof pad 14 is recessed at the location of the drainage gap 13 to form a water leakage gap. That is, in these embodiments, by forming a water leakage gap at the location of the waterproof pad 14 corresponding to the drainage gap 13, water in the annular groove 12 can be discharged from the annular groove 12 along the water leakage gap and the drainage gap 13, preventing water accumulation in the annular groove 12.

[0035] Optionally, in some embodiments of this utility model, an elastic pressure plate 30 is further included.
