Document Type and Number:
WIPO Patent Application WO/2014/019377
Kind Code:
A1
Abstract:
A torsion spring resetting apparatus comprising: a handle module (1), a lock face (2), a resetting module (3), and a clutch (4). The resetting module (3) consists of an upper resetting block (31), a lower resetting block (32), and a resetting torsion spring (33), where the three are assembled concentrically. The upper resetting block (31) is fixed onto the lock face (2) and kept permanently still relative to the lock face (2); the lower resetting block (32) is sleeved onto a positioning rod (21); the resetting torsion spring (33) is sleeved onto the lower resetting block (32), where both are allowed to rotate around the positioning rod (21). Compared with an existing resetting transmission structure, the torsion spring resetting apparatus streamlines parts, conserves costs, reduces size, is convenient to assemble, and has reduced manufacturing costs.
