WIPO Patent Application WO/2023/241112

A1

A combined force supply mechanism, comprising a cylinder body (11), a rod seat (12), a nail shooting rod (13), and a spring unit, wherein the spring unit is provided with: at least two layers of layered spring portions (14) arranged in a moving direction of the rod seat (12); and a linkage sheet (15) arranged between two adjacent layers of layered spring portions (14) and configured to link the two layers of layered spring portions (14), wherein each layer of layered spring portion (14) comprises at least one force supply spring (141), all of the force supply springs (141) in each layer of layered spring portion (14) are of the same type, and the force supply springs (141) in the two adjacent layers of layered spring portions (14) are of different types. After a plurality of layers of layered spring portions (14) are combined with each other, a larger comprehensive elastic coefficient can be formed in a unit space to supplement a larger nail shooting power and meet the use of a high-power nail gun. The present invention further relates to a driving device having the combined force supply mechanism, and a nail gun having the driving device.
