Meanwhile, the driving mode is simple in structure and convenient to realize. Specifically, the driving mechanism 40 in this embodiment is a stepping motor, and the movement of the inner diameter line 12 in each joint module 10 is controlled by the stepping motor. When the stepping motor rotates forward, the inner diameter line 12 on each joint module 10 is drawn close to bend the joint. When the stepping motor is reversely rotated, the inner diameter line 12 of each joint module 10 is released, so that each joint module 10 is straightened under the tensile force of the elastic member 20.

A USB interface can be arranged on the control piece and can be powered by the charger baby. The lasso in this embodiment also includes a smart chip module with interfaces (USB interface and IO interface), which also carries a communication module Wifi.

In this embodiment, the lasso further comprises X-wheels, which are arranged on the joint modules 10 and which are located outside the joint modules 10, in a well or in a cave, which may run in a rugged environment, by means of which a plurality of joint modules 10 may be brought to a destination.

In this embodiment, the lasso and the viewing environment may be controlled by the mobile phone software APP. Specifically, the network is rapidly configured through the lasso, so that pictures shot by the camera can be transmitted to the mobile phone in real time, and ground personnel can conveniently check the pictures. Through controlling the LED lamp, the external condition can be clearly seen in the dark underground. The lasso in this embodiment can be fixed in the one end of rope or rod or other rectangular object (can select according to actual conditions), stretch into the well or cave with the rope or rod, through cell-phone search control bottom plate AP, connect this AP, open the picture that the software looked over the camera transmission on the lasso in real time to according to actual picture control lasso. When the telescopic rope is close to a target person or object, the sucker or the X-shaped wheel is opened or not according to needs to be used for fixing the tail end of the telescopic rope, so that the phenomenon that the target person or object cannot be correctly sleeved due to gravity center change after the telescopic rope is bent is avoided. By controlling the stepping motor, the stepping motor pulls the inner diameter line 12 in the joint module 10 through rotation, so that each joint module 10 is bent at the same angle, and when the overall lengths of the plurality of joint modules 10 are different, the bending angles are different. When the plurality of joint modules 10 are bent end to end, the plurality of joint modules 10 form a circle, and at this time, the electromagnetic frame of the joint module 10 at one end can be opened and sleeved on the joint module 10 at the other end, and then rescue can be performed.

In this embodiment, the lasso may control the movement of the inner diameter line 12 through the control of the smart chip, the camera, the LED lamp and the stepping motor to make the plurality of joint modules 10 form an annular structure (which may be circular), and finally lock the target person or object.
