[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model through specific embodiments with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0019] Figure 1Schematic structural diagram of a device for disassembling a drill chuck sleeve. The device for disassembling a drill chuck sleeve includes: a main body lever 1, a safety pin 2, a connecting plate 3, and a clamping member 4. One end of the main body lever 1 is connected to the connecting plate 3 through the safety pin 2, and the other end is an operating part for operation by a staff member. The main body lever 1 can rotate around the safety pin 2. The connecting plate 3 is fixedly connected to the clamping member 4. In one embodiment, the connecting plate 3 and the clamping member 4 can be connected by welding. In one embodiment, the connecting plate 3 and the clamping member 4 can be fixedly connected by riveting, screws, snap fasteners, etc. In one embodiment, the connecting plate 3 and the clamping member 4 can be integrally formed. In one embodiment, the connecting plate 3 includes a first connecting plate and a second connecting plate located on both sides of the main body lever 1. The safety pin 2 penetrates through the first connecting plate, the main body lever 1, and the second connecting plate.
[0020] The main body lever 1 of the device for disassembling a drill chuck sleeve is made of a high-strength material, such as made of steel, to ensure the durability and stability of the device. One end of the main body lever 1 connected to the safety pin 2 adopts an arc design, and the arc surface on the side close to the clamping member 4 is serrated to ensure that the friction force of the tool meets the use requirements. When the main body lever 1 is rotated around the safety pin 2 through the operating part of the main body lever 1, the serrated arc surface can press against the clamping member 4.
[0021] Figure 2 Side view of a device for disassembling a drill chuck sleeve according to an embodiment. The clamping member 4 of the device for disassembling a drill chuck sleeve is used to clamp the drill chuck sleeve. In one embodiment, the inner wall of the clamping member 4 adopts a conical design to adapt to different specifications of the chuck sleeves. When disassembling the drill chuck sleeve, the clamping member 4 of the device is sleeved on the drill chuck sleeve to be disassembled. Because the inner wall of the clamping member 4 is conical, after applying force to the drill chuck sleeve during disassembly, the drill chuck sleeve will be tightly locked. Then, force is applied in the disassembly direction through the main body lever 1, and the serrated arc surface of the main body lever 1 will catch the clamping member 4, and then drive the drill chuck sleeve to rotate, achieving the purpose of quickly disassembling the chuck sleeve. Thus, through the restraining effect of the main body lever 1 and the clamping member 4 on the drill chuck sleeve, the effect of easily and quickly disassembling the drill chuck sleeve is achieved.
[0022] In one embodiment, in order to further improve the disassembly efficiency and safety, anti-slip patterns and / or elastic pads can be provided on the inner wall of the clamping member 4 to increase the clamping force and protect the drill chuck sleeve from damage.
[0023] In one embodiment, in order to further improve the disassembly efficiency and safety, anti-slip patterns and / or elastic pads can be provided on the outer wall of the clamping member 4 to enhance the friction force between the serrated arc surface of the main body lever 1.
