Abstract
The utility model discloses a transmission mechanism of a hedge trimmer, which belongs to an importation power component of the hedge trimmer in garden greening tools. The transmission mechanism of the hedge trimmer is composed of the following components: a gear case, an eccentric gear, a connecting rod, a thrust plate, etc. The thrust plate and the gear case in the transmission mechanism are mainly designed to a fixed connection structure, such as screw connector or other connection. When the eccentric gear operates a driving blade set for performing trimming, vibration and displacement of the improved thrust plate because of being driven are prevented, thereby reducing the abrasion of a connecting pin by a circular hole on the thrust plate, and greatly improving service life of the transmission mechanism. Simultaneously the gear box, the thrust plate and the connecting rod are respectively provided with an oil injection opening for injecting butter for the eccentric gear in the gear case. Therefore the lubrication can be performed without opening the gear case thereby obtaining simple operation and high convenience in lubrication.

Fig. 2 is connected structural representation on the casing for thrust plate.
Fig. 3 is connected structural representation on the bottom for thrust plate.
Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 3,1. gear-box, 11. casings, 12. bottoms, 2 little bearings, 3. thrust plate, 31. circular holes, 4. connecting rod, 41. connecting holes, 5. needle bearing, 6. eccentric gear, 61. eccentric blocks, 62. connecting pins, 7. screw, 8. set of blades, 9. oil filler point.
The GREEB HEDGE MACHINE transmission mechanism is to be used to drive the power part that set of blades is pruned in electric hedgerow machine or the pneumatic GREEB HEDGE MACHINE, and this transmission mechanism is by gear-box 1 and be installed in eccentric gear 6 in the gear-box, connecting rod 4, thrust plate 3 etc. and constitute.With shown in Figure 1, Fig. 1 left side is that front portion, Fig. 1 right side of this transmission mechanism is the rear portion of this transmission mechanism.
Described gear-box 1 is that the bottom 12 by the casing 11 on top and bottom is fastened and connected mutually with screw and forms, and is equipped with oblong oil filler point on casing 11 and bottom 12, also is embedded with little bearing 2 in casing and the bottom respectively.
Described eccentric gear 6 is the power input part of gear-box 1, is respectively equipped with two circular eccentric blocks 61 on the end face of eccentric gear both sides, and these two circular eccentric blocks are that the center is symmetrical distribution with eccentric gear 6 centers of circle.Simultaneously, the circle centre position of this eccentric gear also is provided with connecting pin 62, outer respectively eccentric gear 6 both sides that are exposed at, the two ends of connecting pin.
