[0028] As Figure 1 、 4As shown in Figure -5, a first reinforcing protective plate 2 is installed on the side of the anti-pry handle lock body 1 away from the inner cover plate 12; a threaded hole 21 is opened on the outer side of the first reinforcing protective plate 2; a threaded hole 21 is opened on the outer side of the inner cover plate 12; a screw rod 22 is installed inside the threaded hole 21; a special-shaped nut 23 is threadedly connected to the outer side of the screw rod 22; during operation, after the inner cover plate 12 is installed, the screw rod 22 is passed through the anti-pry handle lock body 1 to the first reinforcing protective plate 2 and the inner cover plate 12, and then a flathead screwdriver is used to... One end of the screw rod 22 is fixed, and the special-shaped nut 23 is rotated using a special wrench to install the first reinforced protective plate 2 on the outside of the anti-pry handle lock body 1, thus protecting the anti-pry handle lock body 1. During the use of the anti-pry handle lock body 1, if it is subjected to violent demolition, the first reinforced protective plate 2 cooperates with the inner cover plate 12, which greatly increases the strength of the anti-pry handle lock body 1. At the same time, because the screw rod 22 needs to be limited at both ends before it can be removed, the safety of the anti-pry handle lock body 1 is greatly enhanced.

[0029] like Figure 4 As shown, the anti-pry handle lock body 1 has a feed inlet 3 on the side near the first reinforcing protective plate 2; the feed inlet 3 is internally threaded with a sealing screw 31; during operation, when the internal mechanical device of the anti-pry handle lock body 1 experiences a high coefficient of friction due to long-term use, the sealing screw 31 is rotated to inject grease into the anti-pry handle lock body 1 through the feed inlet 3, and then the sealing screw 31 is used to seal the feed inlet 3. Under long-term use of the lock, the coefficient of friction is prone to increase, resulting in severe wear inside the anti-pry handle lock body 1. Therefore, injecting grease into the anti-pry handle lock body 1 through the feed inlet 3 reduces the coefficient of friction and increases the service life of the anti-pry handle lock body 1.

[0030] like Figure 1 As shown, a fixing screw 4 is installed on the outer side of the inner cover plate 12; the fixing screw 4 is located on one side of the anti-pry handle lock body 1; when working, the connection between the inner cover plate 12 and the anti-pry handle lock body 1 is more firm and stable through the fixing screw 4, which further enhances the overall strength and stability of the device.

[0031] like Figures 1-2 As shown in Figure 4, the anti-pry handle lock body 1 is equipped with limit hooks 5 at both ends; during operation, after the anti-pry handle lock body 1 is installed, the limit hooks 5, due to their shape, will hook into the inside of the door, which has the function of enhancing the stability and impact resistance of the anti-pry handle lock body 1.

[0032] like Figures 1-4As shown, the anti-prying handle lock body 1 is externally installed with a second reinforcing protective plate 6; during operation, the second reinforcing protective plate 6 is installed on one side of the anti-prying handle lock body 1, cooperates with the inner side cover plate 12 and the first reinforcing protective plate 2, and further improves the impact resistance and strength of the anti-prying handle lock body 1 as a whole.

[0033] As shown in Figures 1-4 , 7, the anti-prying handle lock body 1 is composed of titanium alloy material; the titanium alloy material has the characteristics of high strength and corrosion resistance, so that the anti-prying handle lock body 1 has a longer service life while having high strength.

[0034] The working principle is that the anti-picking handle lock body 1, the rotating handle body 11 and the inner cover plate 12 are installed on the house door, and attention is paid to the fact that the inner cover plate 12 faces the inner side of the house door. When the inner cover plate 12 is installed on the outer side of the anti-picking handle lock body 1, the gear 13 is sunk into the inside of the tooth groove 14 and is engaged with the sliding rack 17. When normally used, the rotating handle body 11 can be rotated to open the house door, and at the same time, the gear 13 outside the rotating handle body 11 drives the sliding rack 17 to slide outside the sliding column 15. When the house door is opened and the hand is released, the reset spring 16 rebounds to reset the sliding rack 17 to the gear 13. When the resident needs to lock the door, the remote control micro servo motor 18 is driven to rotate the sliding column 15 inside the sliding rack 17, the limiting teeth 101 enter the limiting groove 100 inside the sliding groove 19, the sliding rack 17 is limited, the gear 13 is stuck at this time, and then the rotating handle body 11 cannot be rotated to open the door. When the fixed handle of the handle lock outside the house door is used, when the resident temporarily goes out, if the wind blows and causes the house door to suddenly close, the resident cannot enter the house, which affects the use experience of the resident. Therefore, whether the sliding rack 17 limits the gear 13 reduces the situation that the resident temporarily goes out and accidentally causes the house door to close and cannot enter. At the same time, the limiting of the sliding rack 17 to the gear 13 and the rotating handle body 11 further increases the safety. At the same time, the inner cover plate 12 is installed on the inner side of the house door, which reduces the influence of violent breaking outside the door. After the installation of the inner cover plate 12 is completed, the screw rod 22 is inserted through the anti-picking handle lock body 1, the first reinforcing protection plate 2 and the inner cover plate 12, and then one-end of the screw rod 22 is fixed by using a screwdriver. The special wrench is used to rotate the special-shaped nut 23 to realize the installation of the first reinforcing protection plate 2 outside the anti-picking handle lock body 1 to protect the anti-picking handle lock body 1. In the process of using the anti-picking handle lock body 1, if violent breaking occurs, the first reinforcing protection plate 2 cooperates with the inner cover plate 12 to greatly increase the strength of the anti-picking handle lock body 1. At the same time, because the screw rod 22 needs to be limited at both ends, the anti-picking handle lock body 1 can be removed, which greatly enhances the safety of the anti-picking handle lock body 1. When the anti-picking handle lock body 1 causes the internal mechanical device to have a large friction coefficient due to long-term use, the sealed screw 31 is rotated, the lubricating grease is injected into the anti-picking handle lock body 1 through the feeding port 3, and then the feeding port 3 is sealed by using the sealed screw 31. In the case of long-term use of the lock, the friction coefficient is likely to increase, which causes the anti-picking handle lock body 1 to be seriously worn. Therefore, the lubricating grease is injected into the anti-picking handle lock body 1 through the feeding port 3 to reduce the friction coefficient and increase the service life of the anti-picking handle lock body 1. The direct connection between the inner cover plate 12 and the anti-picking handle lock body 1 is more firm and stable by fixing the screw rod 4, which further enhances the overall strength and stability of the device. After the installation of the anti-picking handle lock body 1 is completed, the limiting hook 5 is hooked to the inside of the house door due to the shape.The second reinforcing protection plate 6 is installed on one side of the pick-resistant handle lock body 1, cooperates with the inner side cover plate 12 and the first reinforcing protection plate 2, and further improves the impact resistance and strength of the pick-resistant handle lock body 1 as a whole.

[0035] The basic principle, main features and advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
