This utility model relates to a ratchet wrench, belonging to the field of tool technology. The wrench includes a handle-shaped housing, with a locking component and a wrench head mounted on the front end of the housing via fasteners. The locking component has a locking position and an unlocking position that can be moved along the length of the housing. The wrench head has a positioning state corresponding to the locking position and a rotational state around the central axis of the housing's length corresponding to the unlocking position. A push button, forming a sliding pair, is installed near the front end of the housing. The push button has a natural position and a pushed position that respectively place the locking component in the locking and unlocking positions. This utility model improves the structural design by using a push button, thus making the rotational adjustment of the wrench head more convenient.

The present application belongs to the field of flexible strain sensing, and particularly relates to a deformation couple for a flexible strain sensor, a manufacturing method thereof and an application thereof. The deformation couple for the flexible strain sensor comprises two polymer films adhered to each other face to face. Both of the polymer films have good ductility and flexibility. The two polymer films have different adsorption capacities for electrons during deformation. The manufacturing method of the deformation couple comprises preparing two polymer films, applying a liquid form of one of the polymer films on one of the films to adhere the two films. The application of the deformation couple for the flexible strain sensor comprises sensing the movement of a joint or a muscle, or sensing the writing of a finger or a pen point thereon. The present application has excellent flexibility and stretchability, can adapt to various complex movements and deformations, and meanwhile maintains stable performance. The present application has a self-power supply characteristic, and does not need an external power supply.
