Description

Technical Field

[0001] This utility model relates to the field of tool manufacturing technology, and in particular to a ball head caliper. Background Technology

[0002] Trailer towing devices are mainly used for towing RVs, luggage racks, and small trucks, and are an important component for expanding the cargo capacity of a vehicle. Mechanical trailer towing devices are usually detachably installed at the rear of the vehicle. They consist of a set of trailer hooks that are plugged in or bolted together along the X-axis (front-to-back direction) or Z-axis (height direction), and then secured with ball joints. Ball joints are generally available in 2-inch and 2.5 / 16-inch sizes. When in use, the trailer is equipped with a coupler, which is simply slipped onto the ball joint for towing—simple and convenient.

[0003] Because mechanical trailer towing devices are quite heavy, tools are needed to clamp the ball joint during installation, and then adjust the mechanical trailer towing device before mounting it on a pickup truck. Without tools, it is not user-friendly for women, the elderly, and other people with less strength. Therefore, the market needs a tool that can easily clamp the ball joint and move the towing device.
