The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Fig. 1 and Figure 3 shows that chain saw of the present invention, comprise chain 1, guide plate 2, sprocket wheel 3, casing 4 and outer cover plate 5, also comprise tension knob 7, worm screw 71, worm gear 8, regulate pin 81, as shown in Figure 4, described tension knob 7 is fixed in the end of described worm screw 71, described worm screw 71 and described worm gear 8 engagements, be fixed with cover plate 6 between described casing 4 and the outer cover plate 5, described worm gear 8 is hinged on described cover plate 6 by its polished rod part, make that worm gear 8 can only be that rotate at the center with the axis of worm gear 8 on cover plate 6, as shown in Figure 2, described worm gear 8 is axially arranged with thread spindle 82, and an end of described adjusting pin 81 is provided with screwed hole, and described adjusting pin 81 is realized being threaded with described thread spindle 82 by this screwed hole, as shown in Figure 5, the other end of described adjusting pin 81 is passed by described cover plate 6 and is connected with described guide plate 2.
The outside of described guide plate 2 is provided with clamping device.As shown in Figure 4, described clamping device comprises interconnective clamping knob 9 and nut 91, described casing 4 is provided with screw rod 41, described screw rod 41 pass by described guide plate 2 and with described nut 91 by being threaded, the end face of described nut 91 can contact with the lateral surface of described guide plate 2.As shown in Figure 7, the center of described worm screw 71 is provided with through hole 75, and described nut 91 is arranged in the described through hole 75.The effect of clamping device is a resting guide, and guide plate is not become flexible because of the vibration in the course of work.
Described tension knob 7 inboards are provided with anti-self-rotating mechanism.As shown in Figure 6, described anti-self-rotating mechanism comprises at least one group of spring 72 and steel ball 73, as shown in Figure 7, some hemispherical groove 74 have been periphery on described tension knob 7 medial surfaces, described spring 72 is located in the described outer cover plate 5, and described spring 72 can be pressed into described steel ball 73 in the described hemispherical groove 74.Anti-self-rotating mechanism can guarantee that this tensioning governor motion can not become flexible because of operational vibration.
During use, the turn tension knob, the worm screw that is fixed together with tension knob drives the worm gear rotation, makes the screw thread drive adjusting pin on the worm gear thread spindle carry out lengthwise movement, realizes that the advance and retreat of guide plate are moved, thereby plays the effect of adjusting chain degree of tightness.Behind chain tension, the turn clamping knob since the nut that is fixed together with clamping knob be fixed in casing on screw rod by being threaded, the precession nut can be realized the clamping to guide plate.
