Further, as shown in fig. 4 to 6, a first protrusion 411 and a second protrusion 412 may be provided on an outer circumferential surface of the knob 4. According to an embodiment, and with reference to fig. 5, the first through hole 33 is provided with a driving surface 32. In the illustrated case, when the knob 4 is rotated clockwise, the first protrusion 411 is rotated to the driving surface 32, and the knob 4 is further rotated, and the first protrusion 411 drives the slider 3 to slide to the right side in the direction of the figure to be separated from the hook 21; when the knob 4 is rotated counterclockwise, the second protrusion 412 is rotated to the driving surface 32, and the second protrusion 412 drives the slider 3 to slide to the right side in the direction of the figure to be separated from the hook 21 by continuing to rotate the knob 4. In the above structure, the slider 3 slides in one direction (right side in the drawing) regardless of whether the knob 4 is rotated clockwise or counterclockwise, that is, in a direction in which the hook 21 is disengaged from the catch 31. In this case, the driving member further includes a part capable of driving the slider 3 to slide toward the direction in which the hook 21 engages with the catch 31, which will be exemplarily explained below and will not be described herein too much. According to another embodiment, with reference to fig. 6, the first through hole 33 is provided with two driving surfaces 32, namely a first driving surface 321 and a second driving surface 322. In the illustrated case, when the knob 4 is rotated clockwise, the first protrusion 411 contacts the first driving surface 321, and the knob 4 is further rotated, and the first protrusion 411 drives the slider 3 to slide to the right side in the direction of the figure to be separated from the hook 21; when the knob 4 is rotated counterclockwise, the second projection 412 contacts the second driving surface 321, the knob 4 is further rotated, and the second projection 412 drives the slider 3 to slide to the left side in the drawing direction, thereby engaging with the hook 21. In the above structure, the hook 21 and the engaging groove 31 can be disengaged and engaged with each other by clockwise or counterclockwise rotation of the knob 4. It should be understood that the knob 4 of the present disclosure may be provided with only one protrusion 41, and the hook 21 and the slot 31 may be disengaged and engaged with the clockwise or counterclockwise rotation of the knob 4.

According to another embodiment of the present disclosure, the driving member may also include a pick slidably disposed inside the handle cover 2, and the sliding member 3 is provided with a stopper cooperating with the pick. The shifting piece is pushed to abut against the blocking piece on the sliding part 3, and the shifting piece is continuously pushed to drive the sliding part 3 to slide, so that the clamping hook 21 and the clamping groove 31 are separated.

In an embodiment of the present disclosure, as shown in fig. 3, the handle body 1 may be provided with a second through hole 34 corresponding to the first through hole 33, so that the knob 4 can extend into the inside of the handle body 1 through the second through hole 34, so as to drive the knob 4 from the inside of the handle. In this way, the knob 4 is hidden inside the handle body 1, and the door handle can be conveniently operated by a user, so that the appearance surface of the door handle is smooth.

Further, as shown in fig. 4, the end surface of the knob 4 may be formed with a bar-shaped groove 42 to facilitate rotation of the knob 4, for example, a coin, a key, or other bar-shaped objects readily available in life may be used to drive the knob 4.

In one embodiment of the present disclosure, as shown in fig. 3, the knob 4 is used for driving the locking slot 31 to be separated from the hook 21, the driving member further includes a first elastic member 6 disposed between the sliding member 3 and the handle body 1, and the first elastic member 6 has an elastic force for clamping the hook 21 in the locking slot 31. For example, when the first through hole 33 adopts the structure shown in fig. 5 in which the knob 4 is engaged with the driving surface 32, the slider 3 is pushed to move in the direction of disengaging the hook 21 and the slot 31 regardless of whether the knob 4 is rotated clockwise or counterclockwise, and the slider 3 cannot be restored to the position where the hook 21 and the slot 31 are re-engaged by rotating the knob 4. In the present disclosure, the first elastic member 6 is provided between the slider 3 and the handle body 1, thereby providing the slider 3 with an elastic force moving toward the direction in which the hook 21 and the catching groove 31 are engaged. Of course, when a structure is adopted in which the hook 21 and the hook 31 can be disengaged or engaged with each other with the clockwise or counterclockwise rotation of the knob 4 as shown in fig. 6, for example, the first elastic member 6 may be provided between the slider 3 and the handle body 1. In addition, the elastic force provided by the elastic element 6 to make the hook 21 engaged with the slot 31 can always maintain the hook 21 and the slot 31 in the engaged state, thereby ensuring that the handle cover 2 is not separated from the handle body 1 in a natural state.

Further, in one embodiment of the present disclosure, as shown in fig. 2, a mounting post 23 is rotatably connected to an inner side of the handle cover 3, and the knob 4 is fixed to the mounting post 23; the mounting column 23 is sleeved with a torsion spring 5, one end of the torsion spring 5 is fixed on the handle cover 2, and the other end of the torsion spring is fixed on the mounting column 23 or the knob 4. The torsion spring 5 has an elastic force to drive the knob 4 to return. When the knob 4 is rotated, the elasticity of the torsion spring 5 is overcome, so that the torsion spring 5 is compressed, after the knob 4 is released, the knob 4 rotates reversely under the action of the elastic restoring force of the torsion spring 5, and finally the knob 4 restores to the original position. At this time, the protrusion 41 of the knob 4 no longer abuts against the driving surface 32 of the slider 3, and the slider 3 moves in the direction of engaging the hook 21 with the engaging groove 31 by the elastic restoring force of the first elastic member 6.
