74 equally stretch out upwards, so that the second auxiliary positioning block 762 be driven to extend upwards and the bottom with the link block 64
Another angle of chamfer in portion abuts.So that the sliding block 32 is closely abutted second positioning component 42, and then makes the panel
Unit 50, which is stablized, to be fixed.The second working position will be known as by the location of described panel unit 50 at this time.
Positioning mechanism 100 provided by the invention shortens the impulse stroke of the panel unit 50, improves the positioning
The positioning accuracy of mechanism 100.Furthermore there are two working positions for the tool of positioning mechanism 100, while providing its stability；And structure
Compact, occupied area is small, and the arrangement density of equipment can be improved in same space.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
It encloses.
