[0014] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] like Figures 1-3 As shown, this utility model provides an overload protection and long-term use structure for the locking key of an electric clipper, characterized in that the overload protection and long-term use structure for the locking key of the electric clipper includes: The machine body 10, and the cutter head 20 movably disposed at one end of the machine body; The body 10 is provided with a push rod 11, the upper end of the push rod 11 is provided with a push rod key 12, the front end of the push rod key 12 is provided with a locking key 120, the lower end of the locking key 120 is provided with a limiting member 121, and the end face of the limiting member 121 is provided with an overload protection mechanism 122.

[0016] Specifically, the machine body 10 is equipped with a push rod 11, and the upper end of the push rod 11 is equipped with a push rod key 12. When the push rod key 12 is pushed, the push rod is equipped with push shafts 111 on both sides of the top of the push rod. The front end of the push shafts 111 abuts against the cutter head 20. At this time, the cutter head 20 is equipped with a fixed cutter holder 21. The front end of the fixed cutter holder 21 is connected to the movable upper cutter 22, and the tail end of the fixed cutter holder 21 is connected to the cutter head spring 23. The tail end of the cutter head spring 23 is rotatably connected to the cutter head connecting rod 24. The cutter head connecting rod 24 abuts against the push rod 11, that is, the front end of the push shaft 111 is connected to the cutter head connecting rod 24, thereby driving the adjustment of the cutter head tooth pitch. The push rod key 12 has a locking key 120 at its front end. If the push rod key 12 is pushed violently without being unlocked, the locking key 120 has a limiting member 121 at its lower end, and the end face of the limiting member 121 has an overload protection mechanism 122. At this time, the overload protection mechanism 122 completely abuts against the bottom end face of the limiting member, accepts all the force, withstands abnormal force, protects the locking key 120, thereby protecting the electric clipper and extending its service life.

[0017] In some embodiments, the push rod 11 has a limiting groove 110 at its middle end for accommodating a limiting member 121, and a limiting spring 123 is provided in the limiting groove 110.

[0018] Specifically, when the push rod key 12 at the upper end of the push rod 11 is pushed by an external force, the push rod 11 moves and drives the cutter head 20 to move, thereby adjusting the tooth pitch. When it stops, due to the elastic restoring force of the limit spring 123 in the limit groove 110, the limit member 121 moves upward. At this time, because the lower end of the locking key 120 abuts against the top end of the limit member 121, the locking key 120 is reset and the push rod key 12 is locked to prevent it from moving.

[0019] In some embodiments, push shafts 111 are provided on both sides of the top end of the push rod 11, and the push shafts 111 are connected to the cutter head 20.

[0020] In some embodiments, the cutter head 20 is provided with a fixed cutter holder 21, the front end of the fixed cutter holder 21 is connected to a movable upper cutter 22, the rear end of the fixed cutter holder 21 is connected to a cutter head spring 23, the rear end of the cutter head spring 23 is rotatably connected to a cutter head connecting rod 24, and the cutter head connecting rod 24 abuts against a push rod 11.

[0021] Specifically, the cutter head 20 is equipped with a fixed cutter holder 21. The front end of the fixed cutter holder 21 is connected to a movable upper cutter 22, and the rear end of the fixed cutter holder 21 is connected to a cutter head spring 23. The rear end of the cutter head spring 23 is rotatably connected to a cutter head connecting rod 24, which abuts against a push rod 11. Push shafts 111 are provided on both sides of the top end of the push rod 11. The push shafts 111 are connected to the cutter head 20, that is, the front end of the push shaft 111 is connected to the cutter head connecting rod 24. When the push rod key provided on the push rod 11 is pushed by an external force, the push rod 11 is moved, thereby driving the movement of the cutter head tooth pitch.

[0022] In summary, the overload protection and long-term use structure for electric clipper lock keys of this utility model includes: The machine body 10 includes a cutter head 20 movably mounted at one end of the machine body. Inside the machine body 10 is a push rod 11, with a push rod key 12 at its upper end. A locking key 120 is located at the front end of the push rod key 12, and a limiting member 121 is located at the lower end of the locking key 120. The limiting member 121 has an overload protection mechanism 122. With this design, when the push rod key is subjected to abnormal external force, the lower end of the locking key completely abuts against the overload protection mechanism on the limiting member, preventing damage to the locking key. Its simple structure and reasonable design extend its service life and meet user requirements.

[0023] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
