Title:
FEEDING MECHANISM AND RIVET GUN HEAD
Document Type and Number:
WIPO Patent Application WO/2021/109142
Kind Code:
A1
Abstract:
A feeding mechanism and a rivet gun head provided with the feeding mechanism. The feeding mechanism comprises: a push component (2), an elastic rotating component (3), and a ratchet (4). The push component (2) switches between an initial position and a pushing position, and the elastic rotating component (3) abuts against the push component (2); the elastic rotating component (3) rotates from a first position to a second position when the push component (2) switches from the initial position to the pushing position; when the push component (2) switches from the pushing position to the initial position, the elastic rotating component (3) rebounds from the second position to the first position. The ratchet (4) meshes with a material belt (5), the ratchet (4) has a first direction and a second direction opposite to the first direction along the circumferential direction, multiple clamping positions are arranged on the ratchet (4) in the circumferential direction, and the elastic rotating component (3) is clamped at one clamping position of the ratchet (4). When the elastic rotating component (3) rotates from the first position to the second position, the elastic rotating component (3) moves in the second direction and switches to be clamped at the next clamping position. When the elastic rotating component (3) rebounds from the second position to the first position, the elastic rotating component (3) drives the ratchet (4) to rotate in the first direction so that the ratchet (4) transmits the material belt.
