Technical Field

[0001] This utility model relates to the technical field, and in particular to an object clamping and pulling device. Background Technology

[0002] Currently, production lines in all industries inevitably become outdated or unsatisfactory as the industry progresses and time goes by. Improving production lines is a necessary condition for increasing production efficiency and meeting production needs. For example, in the tobacco industry, cigarette pack storage and discharging equipment is prone to jamming due to differences in the speed of storing or discharging cigarette packs and the distance between cigarette packs. This requires manual intervention to restore order, which is time-consuming, labor-intensive, and reduces machine efficiency.

[0003] Therefore, research and development is now underway to address the aforementioned issues. Utility Model Content
