The invention relates to a novel door lock handle. Comprising a handle shell and a clutch core. A clutch mechanism is arranged in the handle shell; a notch is formed in the clutch core; the clutch mechanism comprises a clutch pin and a driving mechanism; the driving mechanism comprises a pushing block, a motor, a driving shaft and a transmission spring; the pushing block is installed in the handle shell in a sliding mode. The clutch pin is fixedly mounted on the pushing block; a containing cavity used for containing the transmission spring is formed in the pushing block, and the transmission spring is installed in the containing cavity. And a radial pin extending into the spiral space of the transmission spring is arranged on the driving shaft. The transmission spring is adopted to convert rotation of the driving shaft into movement of the pushing block and the clutch pin, an existing electromagnetic driving mode is replaced, the safety problem in the prior art can be solved, the compressible and stretchable characteristics of the transmission spring are utilized, the phenomenon that the clutch pin and the pushing block are stuck can be avoided, and the service life of the clutch pin is prolonged. And the phenomenon that the motor is burnt due to overload is also avoided.
本发明涉及一种新型门锁执手。包括执手壳体和离合芯；该执手壳体内设有离合机构；该离合芯上设有凹口；该离合机构包括离合销和驱动机构；该驱动机构包括推动块、电机、驱动轴和传动弹簧；该推动块可滑动地安装于执手壳体内；该离合销固定地安装于推动块上；该推动块内设有用于收容传动弹簧的容腔，该传动弹簧安装于容腔内；该驱动轴上设有伸入传动弹簧的螺旋空间中的径向销。本发明采用传动弹簧实现将驱动轴的转动转换为推动块和离合销的移动，以代替现有的电磁驱动的方式，可解决现有技术中安全性的问题，且利用传动弹簧的可压缩拉伸的特性，可避免出现离合销和推动块出现卡死现象，也避免出现因过载而烧毁电机的现象。
