Specific implementation mode
The utility model embodiment is described further below in conjunction with the accompanying drawings：
In the utility model embodiment, a kind of range limiter, including shell 1, support plate 2, potentiometer 4, first gear
8, connector 5, transmission mechanism, the support plate 2 is fixed in shell 1, equipped with placement potentiometer 4 above the support plate 2
Pedestal 13, the first gear 8 and the transmission mechanism are set to the lower section of the support plate 2.
The transmission mechanism includes worm screw 6, and worm screw 6 coordinates with the transmission of worm gear 7, and worm gear 7 passes through the 4th gear 11 and shaft
12 transmission cooperations, shaft 12 are coordinated by third gear 10 and the transmission of second gear 9, and second gear 9 engages biography with first gear 8
Dynamic, drive mechanism is rationally, efficiently.
5 upper end of the connector is directly connected to the potentiometer 4, and there are hexagonal indentations at 8 center of the first gear, institute
It states 5 lower end of connector and matches that composition is circumferential to be connected with the groove, pass through connection between potentiometer 4 and first gear 8
Device 5 is connected, simple in structure, and transmission effect is good.
2 lower section of support plate is set there are one holder 3, and for placing first gear 8,15 shape of chassis of the holder 3 is C words
Type annulus, the side that opening direction is engaged with the transmission mechanism, the chassis 15 and three connecting pins 16 of the support plate 2
Connection, the chassis 15 are adapted to the support plate 2 at a distance from the thickness of the first gear 8, set on chassis 15 there are three
Protruding part 14, raised 14 bottom are elliptical cylinder-shape, and top section is round rectangle, and surface is round and smooth, the first gear 8
There is one of circumferential groove, when gear rotates, stable gear position is played the role of in the groove and raised 14 cooperation,
And it is described raised 14 small with the contact area of the first gear 8, raised 14 surface is mellow and full, smooth, during the work time,
The transmission effect of gear will not be impacted.
Every technical staff's notice：Although the utility model is described according to above-mentioned specific implementation mode, this
The invention thought of utility model is not limited to that utility model, any repacking with inventive concept will all be included in this specially
In sharp scope of patent protection.
