The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

As shown in fig. 1-4, the present utility model provides a lock knob, comprising a knob key 23, a knob shaft 22, and a connecting piece 21; the connecting piece penetrates through one side of the knob key 23 and is detachably connected with the knob key 23; the knob shaft 22 is provided with a through hole 225 penetrating along the radial direction of the knob shaft 22, and the knob shaft 22 penetrates through the knob key 23; the connector is detachably connected to either end of the through hole 225, and is mounted on the knob shaft 22 in such a manner that the knob key 23 can be exchanged in both forward and reverse directions.

The connecting member 21 is preferably a machine screw, which penetrates one side of the knob key 23 and is detachably connected with the knob key 23.

The machine rice screw is respectively in threaded connection with the knob key 23 and the through hole 225 in a detachable mode, so that the nut end of the screw is prevented from being exposed on the outer surface of the knob key 23, the cutting of hands is prevented, and the ornamental value is improved.

The connection member 21 may be replaced by a connection pin, a buckle, or the like, which is not limited in this embodiment.

In practical application, the knob shaft 22 is inserted on the rotary shaft 14 of the lock body 1.

Further improved, the device also comprises a spring 24 sleeved on the knob shaft 22; the knob shaft 22 is provided with a first boss 221 which is arranged in a surrounding manner, one end of the spring 24 is propped against the knob key 23, and the other end is propped against the first boss 221.

The spring 24 has two specific arrangements, the first is that a boss is positioned between the bottom of the knob key 23 and the lock body 1, when the knob key 23 is disconnected from the knob shaft 22 in the axial direction, the spring 24 ejects the knob key 23, and when the knob key 23 is connected with the knob shaft 22, the spring 24 fills the gap between the knob key 23 and the knob shaft, so that shaking and slipping of the knob key 23 are avoided.

The second type is that the knob key 23 is located between the boss and the lock body 1, as shown in fig. 2, the knob key 23 is located between the boss and the lock body 1, and a cavity 231 is formed on the knob key 23, the first boss 221 is located in the cavity 231, and the spring 24 abuts against the bottoms of the first boss 221 and the cavity 231 respectively.
