[detailed description of the invention]
For making the object, technical solutions and advantages of the present invention of greater clarity, below by accompanying drawing and real
Execute example, the present invention is further elaborated.It is embodied as however, it should be understood that described herein
Example only in order to explain the present invention, is not limited to the scope of the present invention.Additionally, in the following description,
Eliminate the description to known features and technology, to avoid unnecessarily obscuring idea of the invention.
Refering to Fig. 1, Fig. 2 and Fig. 3, the embodiment of the present invention provides a kind of dress of the forklift position limitation protection containing armlet
Putting, including fender bracket 1, shield arm fixed mount 2 and forklift door frame 9, described fender bracket 1 is by connecting rod 11
Forming with the shield arm 12 being fixedly mounted on connecting rod 11 two ends, described connecting rod 11 may be rotatably mounted at protection
On arm fixed mount 2, also include first proximity switch the 3, second proximity switch 4, sensor block 5, controller 6,
