It is now widely used in highway toll stations and parking lot systems to manage vehicle access and to manage the entry and exit of vehicles. The reduction box is an important part of the barrier gate. Generally, during the production process, the bearing position of the reduction box cover needs to be pressed to facilitate the subsequent bearing installation to meet production needs.

[0003] In order to avoid deviation during the hole pressing process of the box cover, technicians in this field have conducted research and improvements, such as a hole pressing tool for the bearing position of the gate reducer cover with application number CN202020005561.1.
