Title:
ELECTRIC STAPLER, STAPLER DRIVING DEVICE, AND STAPLER POWER SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/045959
Kind Code:
A1
Abstract:
An electric stapler, comprising an overload protection structure of the electric stapler. The overload protection structure of the electric stapler comprises: a driving rack (1), a driving gear (2), and an overload switching device; the overload switching device comprises a transition gear (3), a deflection housing (4), a deflection shaft (5), and a biasing assembly (6); the transition gear (3) is engaged with both the driving rack (1) and the driving gear (2); the deflection housing (4) is rotatably connected to the deflection shaft (5); and when the thrust between the driving rack (1) and the transition gear (3) is greater than a preset value, the transition gear (3) provides a disengagement thrust against a biasing force to the deflection housing (4), so that the deflection housing (4) rotates relative to the deflection shaft (5), and the transition gear (3) is disengaged from the driving rack (1).
