[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The electric tool base in the utility model includes a connecting seat and a supporting seat fixedly connected by rivets. During the production process, the connecting seat and the supporting seat can be cast separately. The manufacturer can use a casting machine with smaller specifications to produce the electric tool base, which is convenient for the production of the electric tool base and the production and processing of the electric tool base. The structure is conducive to reducing the volume of the mold, thereby reducing the cost of the mold; the L-shaped first positioning surface and the second positioning surface are convenient for the positioning and installation of the connecting seat and the supporting seat, reducing the occurrence of misalignment of the connecting seat and the supporting seat during the production process that affects the assembly of the connecting seat and the supporting seat.

[0019] 2. The setting of the positioning holes and the positioning protrusions in the utility model facilitates the positioning and installation of the connecting seat and the supporting seat, avoids the misalignment of the first mounting hole and the second mounting hole during the riveting process of the connecting seat and the supporting seat, reduces the force on the rivets during use, avoids deformation or damage of the rivets, and is beneficial to extending the service life of the power tool base; the positioning holes with gradually changing diameters and the setting of the guide surfaces facilitate the close connection between the positioning holes and the positioning protrusions, and facilitates the quick connection and cooperation between the positioning holes and the positioning protrusions, which is convenient for the rapid assembly and production of the power tool base.

[0020] 3. The provision of the convex edge and the avoidance portion in the utility model is conducive to increasing the contact area between the positioning hole and the positioning protrusion, avoiding deformation and damage of the positioning hole and the positioning protrusion after long-term use; the provision of the reinforcing ribs is convenient for improving the structural strength of the convex edge and avoiding deformation and damage of the positioning hole.

[0021] 4. The support foot arranged below the positioning groove in the utility model can prevent the relative force between the connection part and the positioning groove from being too large during use, which may cause damage to the connection seat, the support seat and the rivet, and is beneficial to prolonging the service life of the power tool base.

[0022] 5. The setting of the air avoidance groove in the utility model prevents the working head from contacting the supporting surface during the use of the electric tool. The setting of the wear-resistant plate can improve the wear resistance of the support seat. The user can replace the wear-resistant plate after long-term use, which is beneficial to saving maintenance costs; the detachable storage box is convenient for the user to collect and clean the waste generated by the operation of the electric tool; the installation groove and the control groove have a simple structure, which is convenient for the disassembly and installation of the storage box, and is convenient for production and processing, and can reduce the quality and cost of the support seat.
