[0008] As a preferred solution of the utility model, the installation groove is located on one side of the lock core fixing plate, and the single movable iron sheet is located in the inner cavity of the handle plate.

[0009] As a preferred solution of the utility model, the limiting rod is located on one side of the mounting hole.

[0010] As a preferred solution of the utility model, the lock core fixing plate is located on one side of the fixing hole, and the inner safety knob is located on one side of the lock core fixing plate.

[0011] As a preferred solution of the utility model, the fixed slot is located in the inner cavity of the handle plate, and a limiting hole is provided on the outer wall of the paddle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, through the fixing slot in the anti-theft door handle knob and the fixing slot on the outer wall of the inner safety knob, when the paddle is inserted into the inner wall of the fixing slot for fixing, the paddle is completely fixed on the inner wall of the fixing slot, and then the installation of the paddle is relatively stable and will not shake. When installing, the paddle can be better aligned with the hole position, making the installation of the safety knob in the anti-theft door simpler and more portable. This product can fix the paddle well, one is convenient when assembling the handle, and the other is fixed, so that the hole position can be well aligned when the door and the handle are installed, and there will be no shaking or movement, which can save time and effort during installation, thereby helping to solve the problem that the existing anti-theft door handle knob is connected by a steel wire passing through a hole, cannot be fixed when plugging and unplugging, and will shake, and when installing, the paddle cannot be well aligned with the hole position due to the shaking of the paddle, the installation is relatively time-consuming and labor-intensive, and the practicability is poor.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0020] A anti-theft door handle knob comprises a handle plate 1, a mounting groove 2 is provided on the outer wall of the handle plate 1, a door handle 3 is rotatably connected to the inner wall of the mounting groove 2, one end of the door handle 3 passes through the mounting groove 2 and extends to one side of the mounting groove 2 where a single movable iron sheet 4 is installed, a limiting rod 5 is installed on the inner wall of the handle plate 1, a lock core fixing plate 6 is embedded in the inner wall of the handle plate 1, a fixing hole 7 is provided on the inner wall of the handle plate 1, an inner safety knob 8 is installed on the inner wall of the fixing hole 7, a fixing slot 9 is provided on the outer wall of the inner safety knob 8, and a paddle 10 is pluggably connected to the inner wall of the fixing slot 9.

[0021] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 A mounting hole 11 is provided on the outer wall of the handle plate 1, and two groups of mounting holes 11 are respectively located on the outer wall of the handle plate 1, the mounting groove 2 is located on one side of the lock core fixing plate 6, the single movable iron sheet 4 is located in the inner cavity of the handle plate 1, the limiting rod 5 is located on one side of the mounting hole 11, the lock core fixing plate 6 is located on one side of the fixing hole 7, the inner safety knob 8 is located on one side of the lock core fixing plate 6, the fixing slot 9 is located in the inner cavity of the handle plate 1, and a limiting hole 12 is provided on the outer wall of the paddle 10.

[0022] The working process of the utility model is as follows: when the anti-theft door handle knob designed by the present invention is used, a fixing hole 7 is opened on the inner wall of the handle plate 1, an inner safety knob 8 is installed on the inner wall of the fixing hole 7, a fixing slot 9 is opened on the outer wall of the inner safety knob 8, and a paddle 10 is plugged and unplugged on the inner wall of the fixing slot 9. Compared with the existing steel wire through-hole connection, the paddle 10 cannot be fixed when plugged and unplugged, and will shake. It is only necessary to open a fixing slot 9 on the outer wall of the inner safety knob 8, insert the paddle 10 into the inner wall of the fixing slot 9, and then When fixing, the paddle 10 is completely fixed on the inner wall of the fixing slot 9, and then the installation of the paddle 10 is relatively stable and will not shake. When installing, the paddle 10 can be better aligned with the hole, making the installation of the safety knob 8 in the anti-theft door simpler and more portable, and more practical. This is beneficial to solving the problem that the existing anti-theft door handle knob is connected by a steel wire passing through a hole, cannot be fixed when plugged in and out, and will shake. During installation, the shaking of the paddle causes it to be unable to align well with the hole, and the installation is time-consuming and labor-intensive, and has poor practicality.
