[0027] like Figures 1-5 As shown, a child lock handle includes a handle 1, a base 2, a cover 3, a connecting shaft 4, and a pressing and rotating mechanism 5. The pressing and rotating mechanism 5 includes a shaped component 6, a reset assembly 7, a rotating seat 8, and a rotating cover 9. The base 2 has a shaped groove 10 that mates with the shaped component 6. The shaped component 6 is installed in the shaped groove 10. One end of the connecting shaft 4 passes through the base 2 and is rotatably connected to the handle 1. The shaped component 6 is fixedly sleeved on the connecting shaft 4. The rotating seat 8 is installed in the base 2, and one end of the rotating seat 8 is connected to the shaped component 6. The rotating cover 9 is fastened onto the rotating seat 8, and the reset component 7 is installed between the rotating seat 8 and the rotating cover 9. The cover 3 is fastened onto the base 2. In use, the connecting shaft 4 is pushed forward 3-5mm by the handle 1, and the connecting shaft 4 pushes the irregular part 6 out of the irregular groove 10. Then the handle 1 can be rotated. During the rotation of the handle 1, the reset component 7 is deformed. Subsequently, under the action of the reset component 7, the handle 1 can be reset. If a child does not press it during use, the handle 1 cannot be rotated. This invention can prevent the risk of children accidentally opening doors and windows.

[0028] like Figure 1 As shown, in this embodiment, a first blocking block 11 is provided at the upper end of the base 2, and a first blocking groove 12 is provided on the first blocking block 11. A second blocking block 13 is provided at the lower end of the base 2, and a second blocking groove 14 is provided on the second blocking block 13. An elastic strip 15 is provided between the first blocking groove 12 and the second blocking groove 14. The elastic strip 15 is provided on the outside of the irregular part 6. The elastic part of this utility model can prevent the irregular part 6 from rotating excessively. When the irregular part 6 comes into contact with the elastic strip 15, it cannot continue to rotate.

[0029] like Figure 1 , 3As shown, in this embodiment, the reset assembly 7 includes at least two sets of reset members 16. The reset member 16 is a spring, and a steel ball is provided between the reset member 16 and the rotating seat 8. When the connecting shaft 4 rotates, the spring can deform. Later, when the connecting shaft 4 rotates to a certain extent, the deformation of the spring is the largest. Then, under the action of the spring and the rotating seat 8, the connecting shaft 4 can be reset. After the connecting shaft 4 is reset, the irregular part 6 can be re-entered into the irregular groove 10.

[0030] like Figure 1 , 2 As shown in this embodiment, the cover 3 is provided with positioning posts 17, and there are at least two positioning posts 17. The positioning posts 17 are cylindrical. The positioning posts 17 of this utility model are convenient for installation and connection with other parts of the lock.

[0031] like Figure 5 As shown in this embodiment, the outer end of the irregular part 6 is symmetrically provided with a plurality of protrusions 18. The protrusions 18 of this utility model can prevent the irregular part 6 from rotating in the irregular groove 10.

[0032] In this embodiment, in order to extend the service life of the present invention, the handle 1, the base 2, the cover 3, and the connecting shaft 4 are all made of metal.

[0033] like Figure 1 As shown, in this embodiment, the cover 3 is provided with a positioning groove 19, and the inner wall of the base 2 is provided with a positioning block 20. The positioning block 20 and the positioning groove 19 are used in conjunction. The cover 3 of this utility model is installed on the base 2 through the positioning block 20 and the positioning groove 19. The installation method is stable and easy to assemble.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
