Problems solved by technology

The existing vehicle-mounted equipment positioning and locking device adopts a straight tube structure. After pulling the handle, it rotates 90° to achieve locking or unlocking. The disadvantage of this device is that it is inconvenient to operate, and the user is required to have a certain amount of arm strength to pull the handle horizontally to the device. To lock or unlock, you need to adjust the angle of the handle to make the device firmly locked, which is time-consuming and laborious to use
