Description

Transverse opening-closing nut dismounting sleeve Technical Field The invention relates to the technical field of mechanical assembly, in particular to a transverse split nut dismounting sleeve. Background The socket wrench is a nut dismounting tool commonly used in mechanical assembly, equipment installation and maintenance operation, is mainly used for sleeving the outside of a nut, and is matched with a manual wrench or an electric tool to realize quick screwing and dismounting of the nut, so that the socket wrench is widely applied to scenes such as industrial equipment, vehicle maintenance and pipeline installation. The conventional disassembly and assembly tool mainly comprises a traditional sleeve, an electric sleeve and an open-ended wrench, and has obvious limitation in practical use. Traditional sleeve and electronic sleeve receive barrel degree of depth restriction, when the bolt extension length was longer, can't hold the bolt completely and with the stable interlock of nut, easily appear overlapping and establish the problem such as not in place, atress skidding, be difficult to normal application of force. Meanwhile, the traditional straight barrel type sleeve is long in axial size, cannot extend into and be placed at a working position from the axial direction under the working condition that the space of a bolt in front is narrow and small, such as a wall body, equipment or a pipeline, and the like, and is poor in applicability. Even if a manual ratchet wrench is adopted, the swing angle is very small due to insufficient operation space, repeated disassembly and re-sleeving of the tool are required, and the operation is complex and the efficiency is low. The open spanner can be clamped into the nut from the side surface, is suitable for long bolts and narrow spaces, but cannot be matched with an electric driving tool for use, does not have a continuous rotation function, can only be wrenched in a reciprocating manner at a small angle, and is time-consuming and high in labor intensity. In conclusion, the existing tool is difficult to meet comprehensive requirements of lateral sleeving, long bolt adapting, narrow space adaptation, electric driving and efficient continuous operation, has low disassembly and assembly efficiency and inconvenient operation under complex working conditions, and cannot well meet the use requirements of industrial field maintenance and assembly. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a transverse split nut dismounting sleeve, which solves the problem that the existing sleeve is suitable for a narrow space operation environment. The sleeve is transversely opened and closed through the fixed semi-ring and the movable semi-ring around the hinge, and can be directly clamped into the nut from the side without being limited by a long bolt and the space at the front end. The top of the fixed semi-ring is fixedly connected with a fixed driving half section, the top of the movable semi-ring is fixedly connected with a movable driving half section, and when the fixed semi-ring and the movable semi-ring are closed, the fixed driving half section and the movable driving half section are butted to form a complete driving connection channel, so that the fixed semi-ring can be matched with standard driving tools such as a hollow electric torque wrench, a manual ratchet wrench, an electric wrench, a torque wrench and the like. The opening and closing locking mechanism is arranged at the free ends of the fixed semi-ring and the movable semi-ring and is used for locking and fixing the closed fixed semi-ring and the closed movable semi-ring, so that the sleeve can be prevented from being sprung out when torque is transmitted, and the sleeve can be transversely opened and taken down after unlocking. Preferably, the locking mechanism that opens and shuts is buckle formula locking mechanical system, including buckle mount pad and buckle locking seat, the inner wall sliding connection of buckle mount pad has the card lock key body, the top fixedly connected with spacing pull rod of card lock key body, the inner wall fixedly connected with round pin body reset spring of buckle mount pad, the bottom of round pin body reset spring and the top fixed connection of card lock key body, when closed sleeve, the card lock key body moves down under round pin body reset spring thrust effect, in the anticreep draw-in groove of card lock seat is gone into to the card, realizes automatic locking. Preferably, the outer wall of buckle mount pad and the outer wall fixed connection of fixed semi-ring, the outer wall of buckle locking seat and the outer wall fixed connection of movable semi-ring, the bottom of kayser round pin body is through the top joint of anticreep draw-in groove and buckle locking seat, and the anticreep draw-in groove is seted up in the wall at buckle locking seat top, the lateral wall of spacing pull rod and the inner wall sliding connect
