[0002] In traditional connection methods, the connection of these materials to steel and to each other mostly uses a sheet metal assembly process mainly based on welding. Welding not only pollutes the environment but also damages the paint patterns of the sheet metal. With the continuous development of technology, currently, the connection between lightweight materials and steel can be carried out by riveting. At present, the riveting machine is mostly used. A riveting machine is a mechanical device used to fix rivets on metal plates or other materials. It forms a permanent connection between two or more materials by applying force to expand the tail (tail handle) of the rivet at one end.

Alternatively, the pulling end of the blind rivet can be inserted into the slot. By operating the air pump and controlling the intake of air, high-pressure gas enters the air chamber through the air inlet pipe, causing the deformable thin wall to indent. The indentation of the deformable thin wall limits the blind rivet, thus completing the fixation of the blind rivet. During the riveting of the blind rivet, the telescopic rod can complete the riveting of the blind rivet through its expansion and contraction. It can rivet self-piercing rivets and blind rivets, has strong adaptability, a wide riveting range, is convenient for riveting operations, and is easy to use;

[0019] 2. The driving motor is controlled to operate through the trigger controller, and the solenoid valve and air pump are controlled to operate through the button controller. When inserting the battery pack into the battery compartment, the semi-circular clamping ball is squeezed and moves. The movement of the semi-circular clamping ball compresses the return spring, causing the return spring to be in a compressed state. When the battery pack is completely immersed in the battery compartment, the arc groove fits with the semi-circular clamping ball, and the return spring loses pressure and returns to its initial state. One end of the return spring moves to drive the semi-circular clamping ball to move, and the semi-circular clamping ball moves into the arc groove, thus completing the connection between the battery pack and the battery compartment. It can quickly install and disassemble the battery pack, and the operation is simple and convenient. Description of the Drawings
