Description

Wire rod restraint mechanism and charging equipment Technical Field The application relates to the technical field of mobile power supplies, in particular to a wire constraint mechanism and charging equipment. Background With the popularity of portable electronic devices, mobile power supplies have become an indispensable accessory for users to go out. In order to improve the convenience of carrying, various designs for integrating the charging wire with the mobile power supply body appear on the market. The initial integration scheme is to directly fix a short fixed-length charging wire on the mobile power supply shell, the tail end of the charging wire is usually provided with a charging connector, and a section of the charging wire close to the tail end can be matched with a buckle or a groove on the mobile power supply shell to form a stable handle or a handle structure. The user can easily pull and carry the mobile power supply through the handle. As shown in fig. 1, patent publication No. CN210724233U discloses such a structure. However, the charging cord length of such designs is relatively short, and when a user needs to charge the electronic device, the too short cord length results in the device having to be placed in close proximity to the mobile power source, greatly limiting flexibility and comfort in use. In order to solve the above problems, designers have designed mobile power products equipped with longer charging wires that allow users to place the device in a more remote, comfortable position while charging, significantly improving the use experience. However, the improvement introduces new problems that firstly, a longer and unfixed charging wire cannot be used as a handle stably, and secondly, in a non-use state, a long wire cannot be effectively tidied on a mobile power supply body, and the long wire can only be wound or scattered outside at will, so that the wire is messy and easy to wind and tie when being carried. In order to realize the functions of supplying power to a long wire and neatly accommodating the long wire, the improved mobile power supply is internally integrated with a wire winding device, namely a winder or a wire winding device, so that the charging wire can be pulled out for a certain length like a tape measure for use, and automatically retracted into the shell through a reset mechanism such as a spring in the winder after being loosened. Various related winder structures have been disclosed in the prior patent literature, and as shown in fig. 2, chinese patent publication No. CN223487904U discloses such structural designs. By introducing such a winding and accommodating mechanism, the portable power source has both the convenience of charging the long charging wire and the automatic accommodating neatness after use. However, this structural design still has a problem in that the end of the charging wire, i.e., the end of the connecting device, must remain free to move in order to achieve smooth drawing and rewinding, and a firm rigid connection cannot be formed with the mobile power supply housing. When the charging wire is in a storage state, the tail end of the charging wire cannot bear large lifting force, and the charging wire cannot be used as a reliable and durable lifting handle to lift the whole mobile power supply. Disclosure of Invention The application mainly solves the technical problem that the existing charging wire cannot be used as a handle when being stored by adopting a winder. According to a first aspect, an embodiment provides a wire restraint mechanism, the wire for supplying power, including a wire body and a plug connected at one end of the wire body, comprising: The shell is provided with a storage position which is used for storing the plug, and the plug is fixed with the relative position of the shell along the lifting direction when in the storage position; the locking piece can slide relative to the shell and has a locking position and an unlocking position in the sliding process, the locking piece locks the wire body in the locking position, and the locking piece releases the locking of the wire body in the unlocking position; the winding assembly is connected with the other end of the wire body and is used for winding the wire body; The plug is in a storage state and is located in the storage position, the locking piece is driven to move to a locking position to lock the wire body, at least part of the wire body is exposed out of the shell, and the plug is separated from the storage position in the non-storage state, and the locking of the locking piece to the wire body is released. In some embodiments, at least a portion of the locking member is located within the receiving location when the plug is in the non-receiving state. In some embodiments, the housing is provided with a stop structure at the storage position, and the plug is fixed with the housing along the lifting direction by the stop structure. In some embodiments, the st
