AI Technical Summary
In existing electric wire trimmers, the connection between the cutter head and the dust collection duct is prone to loosening, resulting in poor stability.
The design employs a combination of front sleeve, middle sleeve, and rear sleeve, and achieves a stable connection through limiting protrusions, limiting grooves, and button structures, ensuring stable docking and separation of the cutter head device and the dust collection duct.
Without applying external force to press the button, a stable connection between the cutter head and the dust collection duct is ensured, preventing loosening and improving the stability of the connection.

Abstract
Claims
1. An electric hair trimming device, characterized in that: The device includes a main body and an air pipe connector. The air pipe connector includes a front sleeve, a middle sleeve, and a rear sleeve. The front sleeve is fixed to the main body. The middle sleeve and the rear sleeve are combined together. The inner wall of the front sleeve has a front inner groove. The middle sleeve has a button. The surface of the button has a pressing part and a button front limit block. The button front limit block is movably embedded in the front inner groove.
2. The electric hair cutting and trimming device according to claim 1, characterized in that: The front end of the front sleeve has an outer tube, and the side of the outer tube has a front conductive terminal. The front conductive terminal is arranged along the axial direction of the front sleeve. The front end of the front conductive terminal is located outside the front sleeve and is electrically connected to the circuit board inside the main body, while the rear end is located inside the front sleeve.
3. The electric hair cutting and trimming device according to claim 2, characterized in that: The outer wall of the outer tube is formed with an outer protrusion, and the inner wall of the rear end of the main body has a main body positioning groove, with the outer protrusion embedded in the main body positioning groove.
4. The electric hair cutting and trimming device according to claim 2 or 3, characterized in that: The inner tube has an inner tube at the front end, which is fitted inside the outer tube. The outer side of the inner tube has a limiting protrusion, and the limiting protrusion has a button groove. The button is set in the button groove. The front side of the button has a pivot and is pivotally connected to the button groove. A spring is sandwiched between the bottom surface of the middle part of the button and the button groove. The surface of the button has a pressing part and a button front limiting block.
5. The electric hair cutting and trimming device according to claim 1, characterized in that: The front sleeve has a front limiting hole at its rear end, and a front inner groove is located at the front end of the front limiting hole. A blocking part is formed between the front inner groove and the front limiting hole.
6. The electric hair cutting and trimming device according to claim 4, characterized in that: The inner wall of the front sleeve is formed with a side limiting groove, which is opened along the axial direction of the front sleeve, and the rear end of the front conductive terminal is located in the side limiting groove.
7. The electric hair-trimming device according to claim 6, characterized in that The inner tube has a fixing seat on its outer side. The fixing seat is inserted into the side limiting groove. The fixing seat is located on the side of the limiting protrusion. The fixing seat is fixed with a middle conductive terminal. The middle conductive terminal is arranged along the axial direction of the middle sleeve. The front end of the middle conductive terminal is connected to the front conductive terminal of the front sleeve for conduction.
8. The electric hair-trimming device according to claim 1, characterized in that: The outer wall of the middle sleeve has a rear sleeve positioning groove, and the inner wall of the rear sleeve has an inner protrusion that engages with the rear sleeve positioning groove of the middle sleeve.
9. The electric hair-trimming device according to claim 1, characterized in that: The rear end of the sleeve has a rear convex ring with a positioning notch.
