[0023] A second pipe 6 is fixedly mounted on the inner wall of the second protective sleeve 2. An annular sealing block 11 is provided at one end of the second pipe 6, and the annular sealing block 11 is clamped in the annular sealing groove 12. It should be noted that the annular sealing block 11 is clamped with the annular sealing groove 12 to ensure the connection and sealing between the first pipe 5 and the second pipe 6.

[0024] A limiting groove is provided in the slider 8, in which a spring 14 is fixedly connected, one end of the spring 14 is connected to a top block 15, and the top block 15 is slidably clamped in the limiting groove, and the top block 15 contacts the bottom wall of the fixed groove 9, and the end face of the top block 15 is inclined. It should be noted that the inclined end face of the top block 15 allows the top block 15 to be displaced backward when it contacts the edge of the fixed groove 9 through the contact of the inclined surface with the edge of the fixed groove 9.

[0025] A first fixing plate 3 is provided on the outer wall of the first protective cover 1, and a second fixing plate 4 is provided on the outer wall of the second protective cover 2.
