[0005] The above technical solution can improve the vertical machining effect of electric drills on the screw bottom holes and screw threads on the side wall of castings. It is simple and convenient to operate, improves machining efficiency, and has high practicality. At the same time, it can position the lever, reduce the burden on the operator who has been holding it all the time, prevent the lever from sliding down naturally, and ensure high safety.

[0006] The present invention is further configured such that the side of the fixed bracket is attached to the casting at a 90-degree angle.

[0007] The present invention is further configured such that the fixed bracket, the fixed seat and the lever are all made of stainless steel.

[0008] The above-mentioned technical solution features a fixed bracket, a fixed base, and a lever with high strength, low density, and excellent corrosion resistance.

[0009] The present invention is further configured such that the front end of the lever is cylindrical.

[0010] The above technical solution makes it easy for people to hold and push it inward.

[0011] The present invention is further configured such that a fixing rod is installed on the other side of the positioning tooth plate, and the other end of the fixing rod extends through to the outside of the fixing bracket and is fitted with a pull plate.

[0012] The above technical solution allows personnel to easily pull the positioning toothed plate outward by setting up a fixing rod and a pull plate.

[0013] The present invention is further configured such that the limiting spring is made of carbon spring steel.

[0014] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. Fix the mounting bracket to the front of the casting with screws. After the mounting bracket is fixed, install the electric drill on the mounting base. After installation, hold the lever and press forward and inward. When the lever is pressed, the bottom end will push the electric drill inward to process. This can improve the vertical processing effect of the electric drill on the screw hole and thread of the side wall of the casting. It is simple and convenient to operate, improves processing efficiency, and has high practicality.

[0017] 2. When moving the lever, first grasp the pull plate and pull it outward. When the pull plate is pulled outward, the positioning tooth plate will move outward due to the fixing rod. When the positioning tooth plate moves outward, it will separate from the tooth groove on the lever. When the pull plate is pulled out to the end, you can use your other hand to continue to screw, push, and pull the lever in and out. This can position the lever, reduce the burden of holding it all the time, and prevent the lever from sliding down naturally, thus ensuring high safety. Attached Figure Description
