The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1-13, present embodiment mainly is made up of fixture 1, universal adjustment assembly 2, drag hook adjusting part 3 and anchor clamps adjusting part 4, wherein universal adjustment assembly 2 is connected by fixture 1 with drag hook adjusting part 3, and anchor clamps adjusting part 4 is fixed on the universal adjustment assembly 2; Described universal adjustment assembly 2 comprises mobile jib 5, sliding ball 6, sliding ball seat 7, fixing head 8 and Fixing clamp-seat 9, wherein has mobile jib groove 10 on the mobile jib 5, and mobile jib 5 and sliding ball 6 are fixing; Sliding ball 6 is inserted in sliding ball seat 7 and can rolls, and both match each other; Fixing head 8 is fixed on the sliding ball seat 7 by screw 11, and fixing head 8 will be slided ball 6 just and be stuck in the sliding ball seat 7, can not drop; Fixing clamp-seat 9 is screwed into sliding ball seat 7, and is connected with sliding ball 6; Described drag hook adjusting part 3 comprises adjustable plate 12, drag hook 13 and syringe pipe 14, and wherein drag hook 13 and syringe pipe 14 are fixed on the two ends of adjustable plate 12, and drag hook 13 and adjustable plate 12 are one, have regulating tank 15 on the adjustable plate 12; Described anchor clamps adjusting part 4 comprises anchor clamps 16, stationary pipes 17, swivel nut 18, expansion link 19, nut 20 and adapter sleeve 21, and wherein anchor clamps 16 have 22, two nuts 20 of two screws and are screwed into screw 22 and are connected with anchor clamps 16; Adapter sleeve 21 penetrates anchor clamps 16 and welding is fixing; One end of stationary pipes 17 and adapter sleeve 21 welding are fixing, and the other end has draw-in groove 23; Swivel nut 18 is enclosed within an end that has draw-in groove 23 on the stationary pipes 17; One end of expansion link 19 is inserted in stationary pipes 17 inside, and the other end is fixed with sliding ball seat 7.
In the present embodiment, fixture 1 comprises holder 24, double-screw bolt 25 and handle nut 26, and an end of double-screw bolt 25 and holder 24 welding are fixing, and the other end is screwed into handle nut 26; Mobile jib 5 and anchor clamps 16 are inserted in holder 24 just, and mobile jib groove 10 and regulating tank 15 are in correspondence with each other; Double-screw bolt 25 passes mobile jib groove 10 and regulating tank 15; Tighten handle nut 26, with universal adjustment assembly 2 and drag hook adjusting part 3 on holder 24.Release handle nut 26, double-screw bolt 25 can be in mobile jib groove 10 and regulating tank 15 activities, and mobile jib 5 and adjustable plate 12 can relatively move, and regulate the position of drag hook 13.
In the present embodiment, have through hole 27 on the sliding ball seat 7, be provided with female thread in the through hole 27; Fixing clamp-seat 9 is provided with external screw thread, and and the female thread of through hole 27 be complementary; Fixing clamp-seat 9 is screwed into the through hole 27 on the sliding ball seat 7, and is connected with sliding ball seat 7 interior sliding balls 6; When Fixing clamp-seat 9 was tightened, sliding ball 6 was at sliding ball seat 7 internal fixation; When Fixing clamp-seat 9 unclamped, sliding ball 6 can move thereby drive mobile jib 5 in sliding ball seat 7 interior 360 ° of rollings; Because mobile jib 5 and adjustable plate 12 are fixed together, adjustable plate 12 also moves together along with mobile jib 5, and adjustable plate 12 drives drag hook 13 and syringe pipe 14, and drag hook 13 and syringe pipe 14 can multi-angle be rotated, and regulates during convenient the operation.
