The utility model relates to a novel gear shaft technical field, concretely relates to a novel gear shaft structure, it includes gear shaft body, one end of gear shaft body is equipped with adjusting assembly, the other end of gear shaft body is equipped with replacement assembly, the one end symmetry of gear shaft body's axle body is provided with moving groove, the inside rotation of the groove body of moving groove that is provided with rotation groove is equipped with screw rod, the inside of moving groove of other side is fixedly connected with limiting shaft, the section outside of gear shaft body is equipped with moving cover, the section outside of moving cover is fixedly connected with gear no.

The utility model discloses a lock shell structure and a handle lock comprising the same. The lock shell structure comprises a shell body and a limiting piece, the shell body is provided with a first side and a second side, the first side is used for arranging a handle head, and a containing cavity is formed in the second side and used for arranging a lock body; wherein the limiting piece is detachably connected to the lock body, a locking hole is formed in the limiting piece, at least part of the locking hole protrudes out of the first side in the direction away from the second side, and the locking hole is used for allowing the counter locking push rod to be inserted so as to limit rotation of the handle head. The locking hole is formed in the detachable limiting piece, and the locking hole in the limiting piece can at least partially protrude out of the first side, so that it can be guaranteed that the back locking push rod and the locking hole have enough contact area, the back locking stability is improved, the difficulty that the locking hole and a boss are integrally formed in the shell body can be avoided, and the service life of the shell body is prolonged. The production difficulty and the production cost of the shell main body are reduced, and the problem that parts in the shell main body are affected due to the fact that the insertion depth of the back locking push rod in the shell main body is increased is also avoided.

The application discloses a micro switch and a car gauge level connector, and belongs to the electrical technical field, wherein the micro switch comprises a fixed seat, a movable seat, a driving part and a normally open contact component; at least two wiring terminals are arranged on the fixed seat; the movable seat is used for abutting against an external part and is movably arranged in the fixed seat through the driving part; and the normally open contact component is moved through the movable seat to complete closure and conduct each wiring terminal. The fixed seat can limit and guide the movable seat, thereby preventing the movable seat from shaking during movement, effectively avoiding deviation and dislocation of the normally open contact component during closure or opening, and enabling each contact to stably abut against each other, so that the reliability and stability of circuit conduction are remarkably improved. The application reduces the number of parts, simplifies the overall structure, is simple to assemble, saves time and labor, improves production efficiency, and is convenient for repair and maintenance.
