After adopting said structure of the present utility model; because the upper and lower end of revolution bow connects described trimmer seat by steel ball structure respectively; the rotational fuel tank body of angling cylinder connects the upper end of described revolution bow by drive link; namely the rotational fuel tank body by angling cylinder drives the rotation of revolution bow; because steel ball structure can guarantee to turn round the upper and lower end of bow in rotation process concentric, and then guaranteed the rotating accuracy of trimmer.
Description of drawings
Fig. 1 is front view structural representation of the present utility model;
Fig. 2 is the syndeton signal left view of top of the present utility model drive link, bottom drive link.
The specific embodiment
See Fig. 1, Fig. 2, it comprises revolution bow 1, trimmer 2, trimmer seat 3, trimmer 2 is loaded on the center of revolution bow 1, turn round the upper of bow 1, the lower end is respectively arranged with episphere connected in star 4, lower semisphere connected in star 5, upper steel ball 6, lower steel ball 7 is flush-mounted in respectively corresponding episphere connected in star 4, in the lower semisphere connected in star 5, upper female cone piece 8 is fitted and is set in the upper part of the upper steel ball 6 that exposes, upper female cone piece 8 is fastenedly connected the upper surface of revolution bow 1, upper steel ball 6 exposes to female cone piece 8, the flange face of upper outside conical blocks 9 is fastenedly connected the upper end installation portion of trimmer seat 3, the mounting-positioning holes 10 of the upper end installation portion of trimmer seat 3 is run through in the bottom of upper outside conical blocks 9, the bottom ball recess 11 of upper outside conical blocks 9 is fitted and is mounted cover the part that exposes to upper female cone piece 8 in upper steel ball 6, the fastening angling cylinder 12 that is equipped with in the top of upper outside conical blocks 9, the rotational fuel tank body 13 of angling cylinder 12 connects the upper end of revolution bow 1 by drive link, lower female cone piece 14 is fitted and is set in the end portion of the lower steel ball 7 that exposes, lower steel ball 7 exposes to lower female cone piece 14, lower female cone piece 14 is fastenedly connected the lower surface of revolution bow 1, the top ball recess 16 of lower outside conical blocks 15 is fitted and is mounted cover the part that exposes to lower female cone piece 14 in lower steel ball 7, lower outside conical blocks 15 bottoms are fastenedly connected with rest pad 17, and the sidepiece of rest pad 17 is fastenedly connected trimmer seat 3;
Be provided with between the upper end installation portion of the flange face of upper outside conical blocks 9 and trimmer seat 3 and adjust pad 18; Can adjust pretightning force to upper steel ball 6, lower steel ball 7 by adjusting pad 18.
