[0027] By adopting the above scheme, when in use, the socket 25 of the required extended function component is inserted into the slot 2 on the main unit 1, so that the transmission block 28 is inserted into the transmission groove on the transmission seat 3, and the locking parts 18 of the two locking members are snapped into the corresponding slots 27 under the action of the spring 15, so that the extended function component can be stably connected with the main unit 1, and then the motor 4 is started to drive the transmission seat 3 to rotate, and the cooperation between the transmission seat 3 and the transmission block 28 can be used to drive the tool of the extended function component to rotate, so that the user can trim the hair conveniently, and the operation is simple and convenient.

[0028] Specific combination Figure 5 and Figure 7 In one embodiment of the utility model, two slide grooves 13 are symmetrically arranged on both sides of the slot 2 in the host 1, and the locking member includes a slide seat 14 located in the slide groove 13, and a positioning hole 21 is opened on the outer wall of the slide seat 14 away from the slot 2, one end of the spring 15 abuts against the inner wall of the slide groove 13, and the other end of the spring 15 is located in the positioning hole 21, and the locking portion 18 is arranged on the outer wall of the slide seat 14 facing the slot 2.

[0029] The slide groove 13 can guide the slide seat 14 , and the positioning hole 21 can position the spring 15 on the slide seat 14 to ensure the stability of the connection between the two.

[0030] Specifically, referring to the figure, the top surface of the locking portion 18 is provided with an upward slope surface 19 , and the bottom surface of the locking portion 18 is provided with a downward slope surface 20 , and the slope of the upward slope surface 19 is greater than the slope of the downward slope surface 20 .

[0031] By setting the upward slope 19, when the socket 25 is inserted downward into the slot 2, the bottom end of the socket 25 will contact the upward slope 19, so that the locking member is pushed to move by the upward slope 19, so that the socket 25 can be smoothly inserted into the slot 2. When the socket 25 is inserted into place, the locking portion 18 will be aligned with the card slot 27. At this time, the locking member will be reset under the action of the spring 15 to lock the locking portion 18 into the card slot 27.

[0032] Through the setting of the downward slope surface 20, when the socket 25 is pulled upward out of the slot 2, the downward slope surface 20 will contact the inner wall of the opening of the card slot 27, thereby pushing the locking piece to move through the downward slope surface to smoothly pull the socket 25 out of the slot 2, and the operation is simple and convenient.

[0033] Since the slope of the upward slope 19 is larger, the locking piece can be pushed to move more easily when the socket 25 is inserted into the slot 2, while the slope of the downward slope 20 is smaller, so more force is required to pull the socket 25 out of the slot 2, so as to ensure the stability of the socket 25 and the slot 2 and prevent the expansion function component from falling off the host 1 without human operation.

[0034] Specific combination Figure 5 In one embodiment of the utility model, two guide grooves 16 are symmetrically arranged in the slide groove 13, and the two guide grooves 16 are distributed on both sides of the spring 15. Two guide blocks 17 are fixedly provided on the outer wall of the slide seat 14, and the guide blocks 17 are located in the corresponding guide grooves 16.

[0035] The cooperation between the guide groove 16 and the guide block 17 can guide the slide seat 14 in the slide groove 13 , thereby further improving the stability of the slide seat 14 moving in the slide groove 13 .

[0036] Specific combination Figure 6 and Fig.10 In one embodiment of the utility model, a main circuit board 8 is fixedly installed in the host 1, and the motor 4, the battery 5, the charging interface 6 and the switch 7 are all electrically connected to the main circuit board 8. A second circuit board 10 is fixedly installed in the host 1, and the second circuit board 10 is fixedly connected to the main circuit board 8 through a plurality of conductive rods 9. A plurality of conductive seats 11 are fixedly installed on the second circuit board 10, and the top ends of the conductive seats 11 are all inserted into the slots 2. A third circuit board 29 is fixedly installed in the socket 25, and a plurality of conductive pins 30 are electrically connected to the third circuit board 29, and the conductive pins 30 correspond to the conductive seats 11 one by one. A controller and a resistance detection circuit are installed on the main circuit board 8, and a resistor is installed on the third circuit board 29.

[0037] Through the setting of the resistance detection circuit, when the socket 25 of the expansion function component is inserted into the slot 2 and the conductive needle 30 is in contact with the conductive seat 11, the resistance value of the resistor of the expansion function component can be detected. Therefore, it is only necessary to install resistors of different resistance values ​​on different expansion function components. After the expansion function component is installed on the host 1, the resistance detection circuit can be used to identify the type of the current expansion function component. Thereafter, the controller can control the output power of the motor 4 so that the speed of the motor can adapt to the current use requirements of the expansion function component. Of course, the resistance detection circuit and the resistor can be replaced by a capacitance detection circuit and a capacitor, or by other detection forms.

[0038] Specific combination Figure 4 and Fig.10 On the basis of the previous embodiment, further, a positioning groove 12 is opened in the slot 2, and a positioning strip 26 adapted to the positioning groove 12 is fixedly provided on the outer wall of the socket 25.

[0039] The cooperation between the positioning groove 12 and the positioning strip 26 can prevent the user from inserting the socket 25 into the slot 2 at a wrong angle, thereby ensuring that the conductive pin 30 is in correct contact with the conductive seat 11.

[0040] Specific combination Figure 4 and Figure 5 In one embodiment of the utility model, the front end of the second circuit board 10 is also provided with three expansion power supply contacts 31 for supplying power to other expansion functional components that require additional power supply. Three conductive columns 32 are fixedly penetrated at the front end of the top surface of the main body 1, and the conductive columns 32 are electrically connected to the corresponding expansion power supply contacts 31, so as to facilitate the supply of power to the expansion functional components that require additional power supply.

[0041] In some preferred embodiments, two magnets 33 are fixedly installed on both sides of the three extended power supply contacts 31 inside the host 1, so as to facilitate the magnetic positioning connection of some extended functional components and improve the stability of the connection between the electrical interface of the extended functional components and the three conductive pillars 32.
