[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , a kind of auxiliary device for facilitating the screwing in of self-tapping screws in this embodiment, including a fixed frame 1. Two clamping plates 2 are slidably connected inside the fixed frame 1. Both of the two clamping plates 2 are L-shaped. Two contact plates 3 are slidably connected inside the fixed frame 1. The right side surfaces of the two contact plates 3 are fixedly connected with first springs 4. The side surfaces of the two clamping plates 2 close to each other are both ramp-shaped. A top wall panel 5 is slidably connected between the two clamping plates 2. The right side surface of the top wall panel 5 is chamfered. The right side surface of the top wall panel 5 is fixedly connected with a second spring 6. The other end of the second spring 6 is fixedly connected with the inner wall of the fixed frame 1. By installing the clamping plates 2, the screws can be clamped, the screws can be prevented from swinging during the tapping process, and at the same time, the screws can be kept in a straight state, improving the stability during tapping. And through the cooperation of the top wall panel 5, the limit on the screws can be actively released when the tapping is about to be completed, thereby completing the installation work of the screws and improving the installation efficiency.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3, inside the fixed frame 1, there are two clamping plates 7. On the side surfaces of the two clamping plates 7 facing away from each other, two third springs 8 are fixedly connected. The other ends of the multiple third springs 8 are fixedly connected to the inner wall of the fixed frame 1. Installing the clamping plates 7 can clamp the clamping plate 2, and transfer the clamping force of the clamping plate 2 to the screw through the restoring force of the third springs 8, so as to clamp the screw body 12. Both of the two clamping plates 7 are slidably connected to the clamping plate 2 close to them. The slidable connection between the clamping plate 7 and the clamping plate 2 can limit the clamping plate 2, so that the clamping plate 2 can stably slide in the fixed frame 1. On the side surfaces of the two clamping plates 7 facing away from each other, limit rods 9 are fixedly connected. The multiple limit rods 9 are slidably inserted into the inner wall of the fixed frame 1. Installing the limit rods 9 can limit the clamping plates 7, so that the clamping plates 7 can stably slide horizontally.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 , on the outer surface of the fixed frame 1, two limit grooves 10 are opened. On the side surfaces of the two clamping plates 2 facing away from each other, sliding keys 11 are fixedly connected. The two sliding keys 11 are both slidably connected to the limit groove 10 close to them. The cooperation of opening the limit groove 10 and the sliding key 11 can limit the clamping plate 2, so that the clamping plate 2 can be kept stable and avoid swinging. There is a screw body 12 between the two clamping plates 2. On the side surfaces of the two clamping plates 2 close to the screw body 12, the material is set as ceramic. Setting one end of the clamping plate 2 as ceramic material can improve its wear resistance, thereby increasing the service life of the clamping plate 2. On the front surface of the fixed frame 1, a clamping frame 13 is fixedly connected. On the upper surface of the fixed frame 1, a hoop 14 is fixedly connected. The hoop 14 is clamped with the clamping frame 13. Installing the cooperation of the clamping frame 13 and the hoop 14 is convenient for installing the fixed frame 1, and at the same time is convenient for installing it on equipment of different models. On the right side of the fixed frame 1, there is an equipment body 15. The equipment body 15 is in contact with the screw body 12, and the hoop 14 is in contact with the equipment body 15. By installing the hoop 14, the friction with the equipment body 15 can be increased, and the fixed frame 1 can be stably installed on the equipment body 15 through the binding force of the hoop 14.

[0033] An auxiliary device for facilitating the screwing in of self-tapping screws in this embodiment can clamp the screw by installing the clamping plate 2, prevent the screw from swinging during the tapping process, keep the screw in a straight state at the same time, improve the stability during tapping, and actively release the limit on the screw when the tapping is about to be completed through the cooperation of the top wall plate 5, so as to complete the installation work of the screw and improve the installation efficiency.

[0034] The working principle of the above embodiments is as follows: First, place the screw body 12 between the two clamping plates 2. When using the device body 15 to install the screw body 12, the device body 15 drives the screw body 12 to rotate and pushes the device body 15. At this time, the two clamping plates 2 can clamp the screw body 12 to prevent the screw from swinging, and at the same time can keep the screw in a straight state, improving the stability during tapping. When the screw body 12 continuously enters the wall, the top wall plate 5 can contact the wall and push the two clamping plates 2 away from each other, so that the two clamping plates 2 can actively release the limit on the screw, thus completing the installation work of the screw and improving the installation efficiency. When the installation of the screw body 12 is completed, the second spring 6 can push the top wall plate 5 to reset, and then the two clamping plates 2 will be pushed to reset by the second spring 6 and the third spring 8, facilitating the next installation. The upper ends of the two clamping plates 2 are made of ceramic material, which can improve the wear resistance of the clamping plates 2, thereby extending the service life of the clamping plates 2. When installing the fixing frame 1, wind the hoop 14 around the device body 15, and then insert the hoop 14 into the card frame 13, so that the card frame 13 limits the hoop 14, thereby enabling the fixing frame 1 to be stably connected to the device body 15. The side surface of the hoop 14 close to the device body 15 is set as a rough surface, which can increase the resistance to the device body 15, thereby enabling the fixing frame 1 to be installed more stably.
