The present invention relates to the field of optical-electronic modules in the field of optical communications. Disclosed is a module structure comprising a torsion spring (500) fixed on a pull ring (800). The torsion spring (500) comprises a left torsion spring (501) and a right torsion spring (502) symmetrically disposed on the pull ring (800). The left torsion spring (501) comprises a first supporting rod (5011), a first spiral hole (5013), a first connecting rod (5014) and a second spiral hole (5012) sequentially connected to each other. The first supporting rod (5011) is a straight rod. The first connecting rod (5014) is an L-shaped rod. The left torsion spring (501) is arranged such that the second spiral hole (5012) is sleeved outside a third rotation shaft (803) of the pull ring (800), and the L-shaped first connecting rod (5014) extends along the pull ring (800), and the first spiral hole (5013) is sleeved outside a first rotation shaft (801). The first supporting rod (5011) is oriented obliquely upwards to form an included angle of less than 90° with a plane in which the pull ring (800) is located. The present invention is characterized in that the pull ring can automatically reset without being manually moved back to an original position and is convenient to use, that components thereof can be assembled and disassembled quickly and a high reliability is attained, and that the module is seamlessly assembled and thus has a good shielding effect. |
