The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing.
Shown in Fig. 1,2,3,4,5,6 and 7, the utility model comprises slide block 1 and fuselage four columns 2; Four jiaos arrange gear 3 on described slide block 1, are provided with tooth bar 4 formative gears, the tooth bar lazy-tongs that are complementary with described four gears at described fuselage four columns 2.Described four gears 3 are arranged on two two ends through the locating shaft 5 of slide block inside; And two locating shafts pass fixedly backing plate 6 of the inboard gear that is fixed on the slide block both sides 1; Described inboard gear fixedly is shaped on screwed hole on the backing plate 6; Fixedly also be provided with gear movable pad 7 outside the backing plate 6 in described inboard; Described two locating shafts support by being installed in the square base spherical outside surface bearing 8 of being with of described gear movable pad 7 sides; Have the mounting hole 7a corresponding with screw on the described inboard gear fixed head 6 on the described gear movable pad 7, gear movable pad 7 and inboard gear fixed head 6 are connected by screw.Also be provided with the gear postive stop baffle of fixing with slide block 19 at described gear movable pad 7 rear sides, described gear postive stop baffle 9 has and only draws unthreaded hole 9a and thrust screw 9b; Described gear movable pad 7 is provided with and the screwed hole 7b that only draws unthreaded hole 9a to be complementary; Described only draw correspondingly to be provided with in unthreaded hole 9a and the thrust screw 9b only draw screw rod 10 and thrust screw rod 11.Respectively be welded with fixedly backing plate 12 of tooth bar at fuselage four column medial surfaces, described tooth bar fixedly has along its length direction on the backing plate 12 and has two row screwed hole 12a; Described tooth bar 3 is fastened on the tooth bar movable pad 13 by screw, the left and right sides has and the fixing mounting hole one to one of the screw 12a on the backing plate of described tooth bar on the described tooth bar movable pad 13, and described tooth bar fixedly backing plate 12 is connected by screw with the tooth bar movable pad.Described tooth bar 3 tops and bottom are provided with the tooth bar postive stop baffle 14 and 15 fixing with fuselage four columns, also comprise the stop bit screw 16 and 17 that is complementary with described tooth bar postive stop baffle 14 and 15.
