Abstract

A novel electric hammer comprises a machine body (23). A drive motor, a gear transmission mechanism, a rotary sleeve (39), and an impact mechanism (42) are mounted in the machine body. The drive motor is connected to an input end of the gear transmission mechanism. An output end of the gear transmission mechanism is connected to the rotary sleeve (39). The electric tool further comprises a drill chuck (22). The drill chuck (22) is hollow. The drill chuck (22) is mounted on the rotary sleeve (39) through a fixing connecting device. The drill chuck (22) is provided with a through hole that an electric hammer bit runs through. The electric hammer bit is mounted in the rotary sleeve (39). The impact mechanism (42) is located behind the electric hammer bit. An outer wall of the drill chuck is provided with a holding member for holding the electric hammer bit. The novel electric hammer makes operation convenient and comfortable, makes hole-boring precise high, and is a novel electric hammer with high processing efficiency.

Description

technical field [0001] The invention relates to the technical field of electric hammer drills, in particular to a drill bit fixture and an electric hammer drill using the same. Background technique [0002] Now commonly used electric hammer drill, refer to figure 1 , Figure 1A and Figure 1B , clamp the drill bit 21 with the electric hammer function on the electric hammer drill to realize the concrete drilling operation; if you need to perform the electric drill function to drill steel or wood, refer to figure 2 , Figure 2A and Figure 2B , it is necessary to connect the drill chuck 101 with the connecting rod 102 and then assemble it on the electric hammer drill, and then clamp the twist drill bit 100 or other drill bits on the drill chuck 101 to realize the drilling operation. When the user replaces the electric hammer function and the electric drill function, the drill chuck 101 needs to be assembled and disassembled. In actual use, the drill chuck 101 will be fre...
