Example (b):

basically as shown in figure 1 and figure 2, an electric hair clipper with side blade adjustment comprises a shell composed of an upper shell 4 and a lower shell 42, an upper shell decoration ring 41 is arranged between the upper shell 4 and the lower shell 42, the upper shell decoration ring 41 is fixedly connected with the lower shell 42 through a bolt, a plurality of buckles 47 are integrally formed on the upper shell decoration ring 41, a plurality of clamping grooves are formed in the upper shell 4, and the upper shell 4 is detachably connected with the upper shell decoration ring 41 through the clamping grooves and the buckles 47. The storage battery is fixed on the lower shell 42 through screws, the storage battery is electrically connected with the motor 5 fixed on the lower shell 42 through screws, a motor pressing plate 51 is arranged on the motor 5, and the motor pressing plate 51 is fixedly connected with the lower shell 42 through screws.

Referring to fig. 3 and 4, a limiting groove 44 with a circular longitudinal section is formed in one side of the upper shell decorative ring 41, a through hole 46 is formed in the limiting groove 44, four limiting points 45 with a circular longitudinal section are formed in the limiting groove 44 along the periphery of the through hole 46, a push button 3 is rotatably connected in the limiting groove 44, and a main gear 31 located in the lower shell 42 is fixed on the push button 3 through a screw.

Push away to turn round 3 and go up horizontal sliding connection and have festival degree piece 37, the cover is equipped with festival degree spring in the festival degree piece 37 outside, and the one end of festival degree spring is fixed and is being pushed away to turn round 3, and the other end of festival degree spring is fixed on festival degree piece 37 (not shown in the figure), festival degree piece 37 and spacing position 45 sliding fit. When pushing away and turning round 3 and rotating, push away to turn round 3 and can take pitch piece 37 to rotate, pitch piece 37 stretches into in spacing position 45 under the effect of pitch spring, so to push away to turn round 3 and carry out spacingly. The push button 3 is positioned on one side of the shell, so that an operator can rotate the push button 3 conveniently.

A head big body 43 is fixed on the lower shell 42 through screws, a fixed cutter 1 is fixed on the head big body 43 through screws, a cutter pad 21 is connected on the head big body 43 in a sliding manner, a movable cutter 2 is fixed on the cutter pad 21 through screws, the movable cutter 2 is made of ceramic materials, a spring seat 35 positioned below the movable cutter 2 is connected on the head big body 43 in a sliding manner, a movable cutter spring 36 is fixedly connected on the spring seat 35, the movable cutter spring 36 is fixedly connected with the cutter pad 21, a rotating shaft 34 is connected on the lower shell 42 in a rotating manner, a gear push rod 32 with a convex-shaped longitudinal section is fixedly bonded on the rotating shaft 34, the protruding part of the gear push rod 32 is abutted against the spring seat 35, and a slave gear 33 meshed with the master gear 31 is fixedly bonded on the gear push rod. The gear ratio of the master gear 31 to the slave gear 33 is 8: 13.

An eccentric shaft 53 is clamped on the knife pad 21, an eccentric wheel 52 is coaxially welded on an output shaft of the motor 5, a sliding groove is formed in the position, deviating from the center of the circle, of the eccentric wheel 52, a convex block is integrally formed on the eccentric shaft 53, the eccentric shaft 53 extends into the sliding groove, and the convex block is in sliding connection with the sliding groove. When the eccentric wheel 52 rotates, the eccentric wheel 52 can drive the eccentric shaft 53 to rotate through the matching of the sliding groove and the lug, and the eccentric shaft 53 can also slide on the eccentric wheel 52.

The specific implementation process is as follows:

the battery supplies power to motor 5, and motor 5 drives eccentric wheel 52 and rotates, and eccentric wheel 52 drives eccentric shaft 53 and shim 21 horizontal hunting, and then shim 21 drives move sword 2 horizontal hunting, so move sword 2 and stationary knife 1 cooperation, can cut the hair, and this is no longer repeated for prior art.

When the relative position of the movable knife 2 and the fixed knife 1 needs to be adjusted, an operator rotates the push button 3, the push button 3 drives the main gear 31 and the pitch block 37 to rotate, the pitch block 37 slides into the limit point 45, due to the effect of the pitch spring, when the pitch block 37 does not slide into the limit point 45, the upper shell decoration ring 41 extrudes the pitch block 37 and the pitch spring, so that the pitch spring contracts, the pitch block 37 can not be obstructed and smoothly extends into the limit point 45, when the pitch block 37 extends into the limit point 45, the pitch spring extrudes the pitch block 37, the pitch block 37 is tightly supported in the limit point 45, and the limit point 45 is matched with the pitch block 37 to limit the push button 3. As shown in fig. 3, when the push button 3 is rotated again, the rotation of the rotation block 37 enters the second limit point 45, and the rotation block 37 repeats the above operations.

The main gear 31 rotates to drive the driven gear 33 to rotate, the driven gear 33 drives the gear push rod 32 to rotate, the gear push rod 32 pushes the spring seat 35 and the movable blade spring 36, the movable blade spring 36 extrudes the knife pad 21, the knife pad 21 drives the movable blade 2 to move for a certain distance, the relative position of the movable blade 2 and the fixed blade 1 is adjusted, and therefore the purpose of adjusting the movable blade 2 is achieved.

Because four limit points 45 are arranged in this embodiment, when the circumference of the rotation distance of the push knob 3 is larger, the circumference of the rotation of the pitch block 37 is larger, as shown in fig. 3, when the push knob 3 rotates for the maximum circumference, the pitch block 37 is matched with the last limit point 45. Since the push knob 3 rotates for the maximum circumference, the push knob 3 drives the main gear 31 to rotate for the maximum circumference, and further drives the gear push rod 32 to rotate for the maximum distance from the gear 33, so that the maximum distance of the movable blade 2 can be adjusted.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The technology, shape and construction parts which are not described in the present invention are all known technology.
