Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As it is shown in figure 1, this utility model includes support 19, worm gear 6, worm screw 7, urceolus 3, interior bar 2, spanner pawl 1, gear 13 and tooth bar 15.
Described support 19 is provided with through hole, the described through hole on urceolus 3 traverse support 19 and support 19 are for being rotatably connected, described urceolus 3 is provided with hexagon through hole, described interior bar 2 is in hexagon and the hexagon through hole being embedded in urceolus 3, one end of described interior bar 2 is connected with spanner pawl 1, the other end is connected with one end of connecting rod 8, and one end of the other end of connecting rod 8 and connecting plate 9 is for being rotatably connected.
Described support 19 is connected with one end of threaded rod 10, the other end of described connecting plate 9 is provided with a through hole, the other end of described threaded rod 10 is threadeded through the through hole on connecting plate 9 with the screwed hole of spacing ring 11, is provided with the first compression spring 12 between described connecting plate 9 and support 19.When rotary spacing ring 11, spacing ring 11 can drive connecting plate 9 threadingly bar 10 to move, so that connecting plate 9 drives interior bar 2 to move along the hexagon through hole of urceolus 3 by connecting rod 8.
Described urceolus 3 is connected with the centre bore of worm gear 6, described support 19 is provided with otic placode, described otic placode is provided with through hole, the two ends of described worm screw 7 are connected through the through hole on otic placode with the centre bore of driven sprocket 5, described worm gear 6 is meshed with worm screw 7, described support 19 and rotates the two ends of axle for being rotatably connected, the described two ends rotating axle are connected through the through hole of support 19 upper ear plate with the centre bore of drive sprocket 14, the gear hole of described gear 13 is connected by unilateral bearing with rotating axle, described drive sprocket 14 is connected by chain 4 with driven sprocket 5.The both sides of described support 19 are provided with guide plate, described guide plate is provided with pilot hole, one end of guide post 16 is connected through the pilot hole of guide plate with one end of tooth bar 15, the other end is connected with pedal 18, described pedal 18 is connected with two guide posts 16, described guide post 16 is provided with the shaft shoulder, is connected by the second compression spring 17 between the shaft shoulder and the guide plate of described guide post 16, and described tooth bar 15 is meshed with gear 13.
