[0006] As a preferred technical solution of the utility model, the inner side of the handle front cover is threadedly connected to an internal threaded tube, the outer wall of the handle rear cover is penetrated by a semi-countersunk machine screw, and the bottom end of the semi-countersunk machine screw is threadedly connected to the inner side of the internal threaded tube.
[0007] As a preferred technical solution of the utility model, the outer wall of the front handle of the one-way lock is slidably connected to the first handle, and the outer wall of the rear handle of the one-way lock is slidably connected to the second handle.
[0008] As a preferred technical solution of the utility model, the top end of the unlocking rod is fixedly connected with an unlocking core, the top end of the unlocking core is provided with a magnet, and the unlocking core and the magnet are located on the inner side of the rear handle of the straight lock.
[0009] As a preferred technical solution of the utility model, the outer wall of the rear handle of the straight lock is provided with a reverse locking tongue, and the outer wall of the reverse locking tongue is threadedly connected with a reverse locking lever.
[0010] As a preferred technical solution of the present utility model, a through hole is formed on the outer wall of the second handle, and the top end of the anti-locking lever passes through the through hole.
[0011] As a preferred technical solution of the utility model, the outer walls of the first handle and the second handle are threaded with fixing bolts, and the bottom ends of the two fixing bolts are respectively connected to the outer walls of the front handle of the flat lock and the rear handle of the flat lock.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model can drive the lock core assembly to rotate through the unlocking rod and the hollow square tube by rotating the front handle of the straight lock and the rear handle of the straight lock, so that the straight lock can be used normally. By pulling the reverse locking dial, the reverse locking dial drives the reverse locking tongue to move, so that the reverse locking tongue can limit the rear handle of the straight lock, so that the rear handle of the straight lock cannot be pressed, so that the straight lock can be reversely locked.
