[0002] An electric drill is a drilling tool that uses electricity as power. It is a common product among power tools and is also the most in-demand power tool product. The working principle of an electric drill is that the rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and power operation, and drives the operating device through the transmission mechanism, driving the gear to increase the power of the drill bit, so that the drill bit can scrape the surface of the object and better penetrate the object.
[0003] When installing a drill bit in a traditional electric drill, most of the drills directly screw the threaded sleeve on the outside of the electric drill to clamp the drill bit inside the electric drill through a knob. When working, the rotation direction of the electric drill is the same as the tightening direction of the threaded sleeve. Therefore, the drill bit will become tighter and tighter during use. Therefore, it is difficult to unscrew the drill bit when replacing the drill bit after using the electric drill. Therefore, it is necessary to design and modify the installation structure of the high-strength drilling drill bit to effectively prevent the inconvenience of disassembly and assembly.

When working, the rotation direction of the electric drill is the same as the tightening direction of the threaded sleeve, so the drill bit will be tightened during use. Therefore, it is difficult to unscrew the drill bit when replacing the drill bit after using the electric drill.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The utility model adopts the method that the operator inserts the mounting block into the groove, and then the operator rotates the locking ring, thereby driving the locking ring to move downward.

[0021] refer to Figure 1 and Figure 2 The surface of the locking ring 9 is fixedly connected with anti-slip teeth 10, the anti-slip teeth 10 are semi-cylindrical, the number of anti-slip teeth 10 is several, the anti-slip teeth 10 are evenly distributed on the surface of the locking ring 9, the anti-slip teeth 10 are welded to the locking ring 9, and the anti-slip teeth 10 are made of stainless steel.
[0022] As a technical optimization solution of the utility model, by setting the anti-slip teeth 10, the friction between the operator's hand and the locking ring 9 can be increased, thereby facilitating the operator to rotate the locking ring 9. At the same time, the anti-slip teeth 10 are semi-cylindrical, and the surface of the anti-slip teeth 10 is arc-shaped, thereby preventing damage to the operator's hand.
[0023] refer to Figure 1 and Figure 2 Support columns 11 are fixedly connected to both sides of the top of the driving rod 1. The internal threads of the support columns 11 are connected to bolts 12. The bolts 12 are movably connected to the locking ring 9. The diameter of the bolts 12 is slightly smaller than the distance between each anti-slip tooth 10.
[0024] As a technical optimization solution of the utility model, through the setting of the support column 11 and the bolt 12, the operator can rotate the bolt 12 so that the bolt 12 is movably connected with the locking ring 9, so that the bolt 12 squeezes the locking ring 9, thereby preventing the locking ring 9 from rotating. At this time, the bolt 12 is located between the two anti-slip teeth 10, and under the action of the anti-slip teeth 10, the locking ring 9 is prevented from rotating.
[0025] refer to Figure 1 , Figure 2 and Figure 4 The top of the locking ring 9 is fixedly connected with a disc 13, the top of the disc 13 is provided with a through opening 14, the interior of the through opening 14 is fixedly connected with a sealing ring 15, the sealing ring 15 is movably connected with the mounting block 2, and the sealing ring 15 is made of silicone material.
[0026] As a technical optimization solution of the utility model, the arrangement of the disc 13, the through hole 14 and the sealing ring 15 can prevent the debris generated during the punching from falling into the interior of the locking ring 9 and thus affecting the normal operation of the device.

[0031] The working principle and use process of the utility model are as follows: when in use, the operator inserts the mounting block 2 into the groove, and then the operator rotates the locking ring 9, thereby driving the locking ring 9 to move downward. When the locking ring 9 moves downward, the inner wall of the locking ring 9 applies a force toward the mounting block 2 to the arc block 7, thereby pushing the arc block 7 and the movable frame 6 to move toward the side close to the mounting block 2 until the movable frame 6 is movably connected with the slot, thereby locking the mounting block 2. Then the operator tightens the bolt 12 so that the bolt 12 is tightly attached to the locking ring 9. At the same time, under the limiting action of the anti-slip teeth 10, the locking ring 9 is prevented from rotating, thereby indirectly preventing the movable frame 6 from moving, thereby improving the stability of the device fixing the drill body 3.
