[0025] like Figures 1 to 4 As shown, this embodiment provides a double end cover, including an upper cover 1 and two end cover bodies 2. The two end cover bodies 2 are integrally connected by a series connection portion 3. The series connection portion 3 is provided with two upper connecting grooves 4. The upper connecting grooves 6 are connected at both ends with vertical holes 5. The vertical holes 5 extend downward and penetrate the end cover bodies 2.

[0026] The bottom end surface of the upper cover 1 is provided with two lower communicating grooves 6, and the upper communicating groove 4 and the lower communicating groove 6 are aligned with each other;

[0027] The upper cover 1 and the series connection part 3 are bonded together. The upper connecting groove 4 and the lower connecting groove 6 are aligned vertically to form a connecting pipe to connect the two end cover bodies. The end surface formed by the series connection part 3 and the end cover body 2 is bonded together with the bottom of the upper cover.
