Further, in the present embodiment, as shown in fig. 2 to 4, a matching comb 1 is further included, and the matching comb 1 is detachably mounted on the sliding connection assembly.

Optionally, the matching comb 1 is detachably mounted on a sliding rail 4 of the sliding connection assembly, wherein a buckle 11 is arranged on the matching comb 1, a hook 42 is arranged on the sliding rail 4, and the matching comb 1 is detachably mounted on the sliding rail 4 through the matching of the buckle 11 and the hook 42. That is, during a specific working process, the matching comb 1 can move together with the slide rail 4.

Still be provided with the gear scale on the casing 5, the person of being convenient for can clearly know and join in marriage how much length that comb 1 has been adjusted by flexible, and is more directly perceived convenient.

Further, as shown in fig. 1 to 6, the slide connection assembly includes: a first rack 51, a second rack 41, a sliding rail 4 and a gear set 3, wherein the first rack 51 is fixedly installed inside the housing 5, the sliding rail 4 is slidably connected with a sliding seat (not shown) arranged inside the housing 5, the second rack 41 is arranged on the sliding rail 4, a first side of the gear set 3 is meshed with the first rack 51, and a second side of the gear set 3 is meshed with the second rack 41; the central position of the gear set 3 is also movably connected with the push button 2.

The push button 2 includes: the promotion portion and with pivot 21 that the promotion portion is connected, pivot 21 with the central point of gear train 3 puts the rotation and is connected, the promotion portion with sliding part sliding connection.

In the present embodiment, the push button 2 can be flexibly pushed, and the gear set 3 is disposed inside the push button 2 through the rotating shaft 21 and can freely rotate around the rotating shaft 21, that is, the first gear 3b (larger gear) and the second gear 3a (smaller gear) rotate at the same angular velocity at any time. When the push button 2 is pushed, the gear set 3 moves along with the push button. Meanwhile, according to the principle of relative movement, the first fixed rack 51 arranged on the inner side of the housing 5 is engaged with the first gear 3b (larger gear) in the gear set 3 to push the first gear 3b to rotate, and meanwhile, the second gear 3a (smaller gear) in the gear set 3 is engaged with the second rack 41 on the sliding rail 4 to push the sliding rail 4 and the push knob 2 to move in the same direction. That is, the sliding rail 4 and the below-described comb 1 are indirectly pushed to reach the desired extension length by the arrangement of the gear set 3, the first rack 51 and the second rack 41 and the movement conversion among each other.

Preferably, to ensure the isotropy of the movement, in the present embodiment, the first rack 51 and the second rack 41 are disposed in parallel with each other. That is, it is necessary to ensure that the push button 2 pushes in any direction, the slide rail 4 and the matching comb 1 also slide in the same direction, that is, the moving directions of the slide rail 4, the matching comb 1 and the push button 2 are always the same.

Further, the gear set 3 includes: the first gear 3b and the second gear 3a are coaxially arranged, the first gear 3b is meshed with the first rack 51, the second gear 3a is meshed with the second rack 41, and the first gear 3b and the second gear 3a are both rotationally connected with the push knob 2.

The radius of the first gear 3b is larger than the radius of the second gear 3 a. Wherein, the profile of tooth (being the modulus) of first gear 3b and second gear 3a is the same, the number of teeth is inequality, is greater than second gear 3a number of teeth (reference circle radius) through setting up first gear 3b number of teeth (reference circle radius), according to the gear drive principle, pushes away the stroke of turning round 2 promotion and can be greater than slide rail 4 and join in marriage the motion stroke of comb 1 to push away the stroke of turning round 2 and enlarge, promptly, join in marriage under the unchangeable condition of comb 1 stroke, it increases the processing to push away the stroke of turning round 2, for example, make original stroke 10mm increase to 20mm, make originally should be for every 0.5mm 2 strokes of turning round 2 grow to 1mm one grade, thereby can improve the promotion that pushes away and turns round 2 and feel.

With the above arrangement, because the number of teeth of the big gear and the small gear of the gear set 3 is different, and the radius of the gear is different, when the gear set 3 rotates at any angle, the arc lengths rotated by any two mass points respectively located on the reference circles of the first gear 3b and the second gear 3a are also different. The push button 2 pushes a sliding stroke S1, and the sliding stroke S2 is generated when the push button is conducted by the sliding connection component to reach the sliding rail 4 (the matching comb 1 described below is installed on the sliding rail 4). The motion effect is known from the foregoing principle as S1> S2.

Of course, in specific implementation, the radii of the two gears can be modified by adjusting the gear ratio of the double-layer gear set 3, so that the sliding rail 4 and the matching comb 1 can move telescopically by different distances under the condition that the push knob 2 pushes a certain stroke.

Due to the existence of the transmission ratio of the gear set 3, a small operation force is applied to the push button 2, and the amplification effect of the force of the gear set 3 can be converted into a relatively large operation force to push the slide rail 4 to do linear motion, so that the characteristic of labor saving is achieved.

In this embodiment, the gear set 3 may be made of various materials, such as POM, brass, etc., preferably plastic parts made of POM (polyoxymethylene resin), and one large gear, one small gear, and two coaxial gears (i.e. the first gear 3b and the second gear 3a) are stacked and tightly combined together without mutual deflection, and at any moment, the angular velocities of the gears are the same, and the tooth shapes of the gears are the same, i.e. the module m, wherein the number of teeth of the second gear 3a is Z2, and the number of teeth of the first gear 3b is Z1.

The material of the slide rail 4 is also preferably plastic made of POM material.

The working principle of the embodiment is as follows:

referring to fig. 5 and 6, when the user pushes the push button 2, the first gear 3b of the gear set 3 moving along with the push button rotates around the rotating shaft 21 under the meshing action of the first rack 51 inside the housing 5, that is, after the push button 2 pushes, the first gear 3b translates along with the push button 2 and moves around the central rotating shaft 21 in a self-transmission manner. Synchronously, the second gear 3a is engaged with the second rack 41 of the slide rail 4, and drives the slide rail 4 to move forward. The final effect is: the push button 2 is pushed to indirectly push the slide rail 4 and the matching comb 1, and the movement stroke S2 of the push button 2 is larger than the movement stroke S1 of the slide rail 4 (namely the matching comb 1).

Under the condition of product shape determination, the module tooth number of the gear set 3 and the tooth number of the first rack 51 and the second rack 41 can be freely defined, so that the stroke sizes of the slide rail 4 and the matching comb 1 can be freely adjusted under the condition that the push button 2 pushes a determined stroke, and the adjustment method is to modify the module and the tooth number of the first gear 3b and the second gear 3a of the gear set 3, namely to modify the sizes of the gear reference circle radius R1 and the radius R2.

According to the simple knowledge of gear and rack transmission, the corresponding relationship between the pushing stroke S1 of the pushing button 2 and the sliding stroke S2 of the sliding rail 4 (i.e. the matching comb 1) in the present embodiment is described as follows:

S2＝S1*Z2/Z1

it can be seen that the push stroke S2 is proportional to the number of teeth Z2 of the second gear 3a and inversely proportional to the number of teeth Z1 of the first gear 3 b. When Z1 is Z2, S1 is S2.

Preferably, in this embodiment, the number of teeth Z2 of the second gear 3a is smaller than the number of teeth Z1 of the first gear 3b, so S2< S1 exists, that is, the push button 2 can generate a standard stroke for the comb 1 (driven by the slide rail 4) to slide 10mm even when pushed by a large stroke of 10-20 mm (or more), the stroke of the push button 2 is enlarged, the finger sliding amplitude of the user pushing the push button 2 to move a basic gear is increased, the pushing hand feeling is improved, the situation is not so tight, and the experience degree is better.

The application also provides a hair clipper, which comprises the telescopic pushing device of the matching comb 1. The specific technical features of the telescopic pushing device of the matching comb 1 are described above, and are not described herein again.

According to the sliding connection assembly and the push button, on the premise that the push button is pushed, the push button and the sliding connection assembly can be relatively displaced relative to the shell, so that the purpose of telescopic pushing adjustment is achieved, the requirement of a user is met, the adjustment range is large, and the user experience is good; in this application, push away to turn round can promote in a flexible way, the gear train is pushing away through the pivot setting and is turning round the inboard and can wind the pivot free rotation. When the push button is pushed, the gear set moves along with the push button. Meanwhile, according to the principle of relative movement, a fixed first rack arranged on the inner side of the shell is meshed with a first gear in the gear set to push the first gear to rotate, and meanwhile, a second gear in the gear set is meshed with a second rack on the sliding rail to push the sliding rail to move in the same direction as the push button. The sliding rail and the matching comb are indirectly pushed to achieve the required telescopic length through the arrangement of the gear set, the first rack and the second rack and the motion conversion among the gear set, the first rack and the second rack; under the condition of pushing and twisting the comb greatly, the comb can be converted into sliding of the matching comb in a small range, and the comb has the characteristics of simple structure and good operation hand feeling.
