Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An auxiliary protective device for electric drills includes a transparent protective shell 1, a connecting mechanism 2 fixedly connected to the rear side of the transparent protective shell 1, and a dust collection mechanism 3 fixedly connected to the inner wall of the transparent protective shell 1.

[0027] The connecting mechanism 2 includes a connecting tube 21, a connecting ring 22, several sliding holes 23, a push rod 24, and an adsorption magnet plate 25. The connecting tube 21 is fixedly connected to the rear side of the transparent protective shell 1. The connecting ring 22 is welded to the surface of the rear side of the connecting tube 21. The sliding holes 23 are respectively opened on the inner side of the connecting tube 21 and the inner side of the connecting ring 22. The push rod 24 is slidably connected to the inner side of the sliding holes 23. The adsorption magnet plate 25 is welded to the bottom of the push rod 24.

[0028] In this embodiment: by setting the transparent protective shell 1 to be made of transparent material, it can effectively block the flying debris generated during drilling, protect the safety of the operator, and facilitate real-time observation of the work area to ensure drilling accuracy. The connecting pipe 21 can initially connect the transparent protective shell 1 to the electric drill. The connecting ring 22 can support and limit the sliding hole 23 and the push rod 24. The sliding hole 23 supports and limits the push rod 24 and restricts the sliding direction of the push rod 24. The push rod 24 can support and limit the adsorption magnet plate 25 and can drive the adsorption magnet plate 25 to move. After the electric drill and the connecting pipe 21 are initially connected, the adsorption magnet plate 25 can be magnetically attracted to the surface of the electric drill by the movement of the push rod 24, further fixing the electric drill.

[0029] Specifically, such as Figure 4 As shown, the dust collection mechanism 3 includes several baffles 31, three guide holes 32, a guide pipe 33, a dust discharge pipe 34, and a dust collection tank 35. The baffles 31 are fixedly connected to the inner wall of the transparent protective shell 1.

[0030] Specifically, such as Figure 4 As shown, the guide hole 32 is opened at the bottom of the inner wall of the transparent protective shell 1, and the guide tube 33 is fixedly connected to the bottom of the guide hole 32.

[0031] Specifically, such as Figure 4As shown, the dust discharge pipe 34 is fixedly connected to the bottom of the guide pipe 33, and the dust collection tank 35 is threadedly connected to the bottom of the dust discharge pipe 34.

[0032] In this embodiment: by setting baffle 31, dust can be blocked when the electric drill is drilling, and debris and dust can be guided to gather at the bottom of the transparent protective shell 1. Guide hole 32 can guide dust and debris. Guide pipe 33 and dust discharge pipe 34 can provide a path for dust and debris to be discharged smoothly into dust collection tank 35. Dust collection tank 35 can collect dust and debris, making it convenient for users to clean up the collected dust later.

[0033] Specifically, such as Figure 5 As shown, a limit ring 4 is welded to the top of the push rod 24, and the top of the limit ring 4 is engraved with anti-slip texture.

[0034] Specifically, such as Figure 5 As shown, an elastic anti-slip ring 5 is provided on the inner wall of the connecting pipe 21. The elastic anti-slip ring 5 is made of nitrile rubber.

[0035] In this embodiment: by setting a limiting ring 4, the sliding range of the push rod 24 is limited to prevent it from coming out of the sliding hole 23. By setting anti-slip texture, the friction of the hand is increased, making it easier to manually adjust the position of the adsorption magnet plate 25. By setting an elastic anti-slip ring 5, the vibration during electric drill operation can be absorbed, reducing the impact on the protective device and extending its service life. By setting the elastic anti-slip ring 5 to be made of nitrile rubber, the high coefficient of friction and elasticity of nitrile rubber tightly fits the electric drill shell, preventing the protective device from sliding or rotating and improving the safety of operation.

[0036] Specifically, such as Figure 3 As shown, a buffer pad 6 is fitted on the bottom adsorption surface of the adsorption magnet plate 25. The buffer pad 6 is made of silicone material.

[0037] Specifically, such as Figure 3 As shown, the magnetic adsorption plate 25 is made of neodymium iron boron strong magnetic material, and the adsorption surface of the magnetic adsorption plate 25 is set as arc.

[0038] In this embodiment: By setting a buffer pad 6, the elastic deformation capability of the buffer pad 6 allows the adsorption surface to better fit the electric drill shell, increasing the contact area and improving the adsorption effect. By setting a silicone material, the soft and wear-resistant silicone material prevents the adsorption magnet plate 25 from directly contacting the electric drill shell, preventing scratches or magnetization of the metal surface. By setting the adsorption magnet plate 25 to be made of neodymium iron boron strong magnetic material, neodymium iron boron strong magnetic material provides a long-lasting and stable adsorption force. By setting the adsorption surface of the adsorption magnet plate 25 to be arc-shaped, it adapts to the cylindrical shell of the electric drill, so that the magnetic force is evenly distributed, avoiding uneven local force that may cause it to fall off.

[0039] Working principle: First, when installing the protective device, the operator puts the connecting pipe 21 on the electric drill to complete the initial connection. Then, the operator pushes the push rod 24 to move the magnetic adsorption plate 25 along the sliding hole 23, so that the magnetic adsorption plate 25 is in contact with the surface of the electric drill. The magnetic force of the magnetic adsorption plate 25 is used to further fix the protective device. The elastic anti-slip ring 5, with the high friction and elasticity of nitrile rubber, fits tightly against the outer shell of the electric drill to prevent the device from sliding or rotating and absorbs the vibration of the operation. Then, when the electric drill starts drilling, the transparent protective shell 1 blocks the flying debris, protecting the operator and making it easier to observe the work area. At this time, the baffle 31 blocks the generated dust and guides it to the bottom of the transparent protective shell 1. Then, the dust and debris enter the guide pipe 33 through the guide hole 32 and are discharged into the dust collection tank 35 through the dust discharge pipe 34 for collection. Finally, when the drilling operation is completed, the user removes the dust collection tank 35 and cleans it.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
