606 that is equipped with of pull frame 605, can fix a position the sliding position of fixed cover 601, then the operator need rotate the third screw rod 602 of fixing base 501 downside and drive pull frame 605, pull frame 605 can be with fixed cover 601 to the downside, make fixed cover 601 closely contradict with the pipeline 1 outside through the first friction pad 603 of downside, realize fixing base 501 and pipeline 1 between the fixed, at this moment the user can be through the connection between connecting piece 201 and the pipeline 1 of second screw rod 502, when carrying out the connection between second screw rod 502 and the first bevel gear 504, the side that is located fixing base 501 is equipped with the pulling plate 701, the corresponding end that will pass the second screw rod 502 of connecting lug 401 continues to pass pulling plate 701, the pulling plate inside is equipped with tooth piece 703, the sliding plate 701 side, the tooth piece 703 is equipped with tooth piece, the tooth piece 703 is directly pushed down at the side of sliding plate 502 with the second screw rod 502, can be directly connected with the second bevel gear 502 at the position of the corresponding end of the screw rod 502, the realization of the convenient side of the spiral bevel gear 502, the realization is realized with the second screw rod 502, the proper sliding plate 502 is realized in the direction of the sliding plate 502, the sliding step of the sliding plate 502 can be down the screw plate 502, the end of the tooth piece is realized.
