Description

Technical Field

[0001] The present application relates to the technical field of calipers, and in particular to a caliper fixture with angled opening and closing limit. Background Art

[0002] At present, when the retaining spring is assembled on the shaft, it is generally achieved by a caliper. Generally, retaining holes are respectively opened on both sides of the open end of the retaining spring, so that after the plug of the caliper is inserted into the retaining hole, the retaining spring is opened by a handle for installation.

[0003] However, the distance between the two holes on the retaining springs of different specifications is also different, which means that every time the operator installs the retaining spring, he needs to apply force to the handle in advance to make the distance between the two pins on the caliper adapt to the distance between the two holes so that the pins can be smoothly inserted into the holes, which reduces the installation efficiency of the retaining spring and therefore needs further improvement. Utility Model Content
