Further, in order to facilitate the fingerprint connection line 4 to penetrate out of the handle body 1, one side of the connecting groove 6 is provided with an avoiding groove 5, the avoiding groove 5 penetrates through the front end of the handle body 1, the fingerprint connection line 4 is led out from the avoiding groove 5 and penetrates out of the handle body 1. Preferably, the avoiding groove 5 is integrated with the connecting groove 6, and when the rotating shaft 9 is tightly installed in the connecting groove 6, the rotating shaft 9 cannot contact the fingerprint connection line 4, so as to ensure that the fingerprint connection line 4 will not occur the problem of wire bending or scratching. Further, in order to guide the installation of the fingerprint connection line 4, the upper side of the avoiding groove 5 is provided with a guide groove 7, the guide groove 7 is opened at the upper end of the avoiding groove 5, when the fingerprint connection line 4 penetrates through the handle body 1, the guide groove 7 guides the fingerprint connection line 4 to penetrate out of the handle body 1 from the side of the avoiding groove 5 and is located outside the rotating shaft 9, so that the fingerprint connection line 4 bypasses the connecting groove 6 and the rotating shaft 9, preventing the rotating shaft 9 from bending when the handle body 1 rotates.

Further, the front end of the handle body 1 is provided with a step seat 14, and the handle cover 11 is sleeved on the step seat 14. The handle cover 11 is fastened and connected to the middle frame 2 by screws, and the middle frame 2 is usually stably mounted on the door plate, so that the handle body 1 can rotate relative to the handle cover 11, and the unlocking function of the handle body 1 is realized. In particular, in the present embodiment, the handle cover 11 is sleeved on the rotating shaft 9, the guide groove 7 is located at the inner side of the handle cover 11, the handle rotating assembly 8 is mounted in the middle frame 2, and a sufficient accommodation cavity 43 is reserved between the handle rotating assembly 8 and the handle cover 11 to accommodate the fingerprint connection line 4. That is, the fingerprint connection line 4 is located between the inner bottom of the handle cover 11 and the bottom of the handle rotating assembly 8, and the accommodation cavity 43 simultaneously serves as the activity space of the fingerprint connection line 4. When the handle body 1 is rotated, the fingerprint connection line 4 can move in the accommodation cavity 43 and will not contact the rotating shaft 9, so as to have good anti-hinge line effect. Further, in order to connect one end of the fingerprint connection line 4 accommodated in the accommodation cavity 43 to the controller of the intelligent door lock, an opening groove 12 is formed on one side of the handle cover 11. The fingerprint connection line 4 can pass out of the handle cover 11 through the opening groove 12 and is finally connected to the controller. After the controller receives the fingerprint information of the fingerprint module 3 and compares, it is confirmed whether the unlocking can be performed.

[0052] Further, as shown in Figure 3 , 10As shown in Figure 12, in this embodiment, a reinforcing pad 32 is provided at the front end of the handle body 1. The reinforcing pad 32 is fitted onto the rotating shaft 9 and abuts against the rear end of the base 15.

[0056] Further, the embodiment of the present application also provides a smart door lock applying the handle assembly. The handle assembly can be installed on the front panel of the smart door lock. The controller is located on the front panel or the rear panel. The fingerprint connection line 4 is connected to the controller. The handle assembly of the smart door lock can avoid the problems of kinking, scratching and breaking of the fingerprint connection line 4 by arranging the fingerprint connection line 4 between the inner bottom of the handle face cover 11 and the bottom of the handle rotating assembly 8. When the handle body 1 is rotated, the fingerprint connection line 4 only moves at the bottom of the handle rotating assembly 8. The problems of kinking, scratching and breaking of the fingerprint connection line 4 can be avoided. The smart door lock cannot be opened due to the failure of the fingerprint module 3. The structure of the door lock is more compact, and the service life is longer.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
