Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a measuring tool used for measuring the switch stroke of a door handle. Background Art

[0002] The door handles of cars have switch stroke requirements, because the switch stroke is related to whether the door panel lock can be opened normally, so the door handle stroke requirements are very strict, requiring the door handle stroke tolerance range of only 1.0 mm. Whether the manufactured products meet the stroke requirements needs to be measured using measuring instruments. However, currently, pure manual measurement using measuring instruments is prone to large measurement errors. Therefore, it is necessary to design a measuring tool specifically for measuring the switch stroke of door handles to accurately measure whether the switch stroke of the door handles meets the requirements.
