[0036] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0037] As attached Figure 1 To Attachment Fig.12 As shown, an electric clipper comprises a base 1, a driving motor 3 arranged on the base 1, and a blade 4 fixed to the output shaft of the driving motor 3, the driving motor 3 comprises a housing 31 and a driving mechanism 32, the housing 31 has a driving cavity 311 with an opening facing the blade 4, the driving mechanism 32 is arranged in the driving cavity 311, the housing 31 is also provided with a handle 5, the end of the handle 5 away from the housing 31 is provided with a power transmission line 30 for power supply, and the end of the power transmission line 30 is provided with a quick release connector 6. The design of the quick release connector 6 is convenient for removing the power line, and the power line is connected to the power line 30 in a detachable manner, thereby realizing a split design, facilitating the rapid replacement of the power plug, and at the same time, the power line does not need to be hung or dragged on the electric clipper, and the power line is prevented from being entangled on the blade 4, which is convenient for use, carrying, and transportation. When it is needed, the power line can be quickly connected to supply power, which is convenient to operate and directly connected to an external power source, facilitating long-term use in a fixed place.

[0038] As attached Figure 1 To Attachment Figure 7 As shown, in this embodiment, the quick-release connector 6 is a male connector, and a fixing nut 61 is also sleeved on the quick-release connector 6. The inner surface of the fixing nut 61 is provided with an internal thread 611, and the outer peripheral surface of the female connector matched with the quick-release connector 6 is provided with an external thread matched with the internal thread 611. When the male connector and the female connector are plugged together, the fixing nut 61 is rotated to make the internal thread 611 threadably connected with the external thread, so that the male connector and the female connector are fixedly connected together. By adopting a quick-release connector method of a male connector and a female connector, the transmission line 30 and the power supply line are connected simply and quickly. The cooperation between the internal thread 611 and the external thread and the limiting effect of the limiting convex strip 612 on the fixing nut 61 can well limit the axial movement of the transmission line 30 and the power supply line. The connection is firm. When there is no power, just connect the power supply line to charge. The operation is convenient and the external power supply can be directly connected, which is convenient for long-term use in a fixed place. At the same time, the fixing nut 61 can be disassembled by rotating it. The disassembly is convenient, thereby realizing a split design. The power supply line does not need to be hung or dragged on the electric cutting machine, which prevents the power supply line from being entangled during use and the blade 4 from cutting the power supply line. Accidents such as cutting, etc. are prevented, and it is easy to use, carry and transport.

[0039] As attached Figure 1 To Attachment Fig.11As shown, in this embodiment, the power line 30 is also provided with a spring 7 between the quick release connector 6 and the handle 5, one end of the spring 7 is fixedly connected to the handle 5, and the other end of the spring 7 near the quick release connector 6 is a free end. The spring 7 is provided with a conical notch structure at one end near the handle 5 and fixed to the handle 5. When connected, the two shells of the handle 5 are clamped on the groove of the spring 7, and the spring 7 can well limit the swing of the power line 30, prevent the power line 30 from folding at a large angle, so as to avoid the power line 30 from cracking, breaking, or even short circuit and leakage; the notch structure increases the force of the spring 7, and the other end of the spring 7 near the quick release connector 6 is a free end, which presses the inner wall of the spring 7 when the power line 30 swings. Under the pressure of the power line 30, the notch structure of the spring 7 is easier to expand, and the free end of the spring 7 stretches forward. The movable spring 7 can well protect the power line 30.

[0040] As attached Figure 1 To Attachment Fig.11 As shown, in this embodiment, the housing 31 also has a mounting cavity 312 with an opening facing away from the blade 4, and a circuit board 33 electrically connected to the power transmission line 30 and used to control the drive motor 3 is arranged in the mounting cavity 312. The circuit board 33 is placed in the mounting cavity 312 and isolated from the drive cavity 311, effectively avoiding the influence of the drive mechanism 32 on the circuit board 33.

[0041] As attached Figure 1 To Attachment Fig.12 As shown, in this embodiment, the housing 31 is provided with a heat sink 318 located on a side wall of the installation cavity 312, the housing 31 is provided with a decorative cover 8 covering the installation cavity 312, and the rear end of the housing 31 is also provided with a heat dissipation gap 34 connecting the drive cavity 311 and the installation cavity 312. The decorative cover 8 can cover the installation cavity 312 to make the overall appearance beautiful, the heat sink 318 is set in a wave shape, effectively increasing the heat dissipation area, the heat dissipation gap 34 connects the drive cavity 311 and the installation cavity 312, and can guide the heat generated by the drive mechanism 32 from the drive cavity 311 to the installation cavity 312, and finally dissipate it through the heat sink 318, which is conducive to quickly dissipating the heat of the drive motor 3.

[0042] As attached Figure 1 To Attachment Fig.11As shown, in this embodiment, the handle 5 is provided with a switch 51 electrically connected to the power transmission line 30, and the switch 51 is provided with a deformable anti-mistaken touch cap 52. Furthermore, the anti-mistaken touch cap 52 is made of silicone material and is transparent as a whole. The anti-mistaken touch cap 52 can be deformed under strong pressure, which can increase the difficulty of pressing the switch 51, thereby preventing the electric clipper from being turned on due to a slight collision, and the blade 4 from rotating, scratching the user or damaging other items.

[0043] As attached Figure 1 To Attachment Fig.11 As shown, in this embodiment, the driving motor 3 further includes a frame portion 35, and the frame portion 35 is integrally formed with the housing 31. Compared with the technical solution of the prior art in which the frame and the housing are designed separately, the integrally formed frame portion 35 and the housing 31 can be conveniently manufactured as a whole, and the integrally formed structure can also improve the overall strength of the mechanism, improve the overall performance of the cutting machine and ensure the verticality, reduce the use of assembly parts such as bolts, reduce the manufacture of assembly surfaces and assembly grooves or cavities between the frame and the housing, reduce the requirements for assembly accuracy and installation verticality, and can also reduce the product size.

[0044] As attached Figure 1 To Attachment Fig.11 As shown, in this embodiment, the lower end of the frame portion 35 is bent to form a fixing portion 36 fixedly connected to the base 1. When installed, the fixing portion 36 passes through the base 1 and is fixedly connected to the base 1. The bottom of the base 1 is formed with a receiving space 11, and the base 1 is provided with a base hole 12 for the frame portion 35 to pass through. After the frame portion 35 passes through the base hole 12 from top to bottom, the upper end surface of the fixing portion 36 abuts against the upper wall surface of the receiving space 11 and is fixedly connected to the base 1 in the receiving space 11. The structure is simple and the installation is firm. The fixing portion 36 can not only be used for connection, but also provide a supporting force for the housing 31 in the vertical direction to improve the load level of the housing 31.
