For example, the cover stopper 48 is provided at a side of the storage cover 4 opposite to the locking hole 41. After the locking protrusion 521 described later is pulled out of the locking hole 41, the end of the storage lid 4 where the locking hole 41 is located can rotate outward approximately around the lid stopper 48 as the rotation axis (the edge of the cross section of the end of the storage lid 4 where the locking hole 41 is located can be an arc with the lid stopper 48 as the rotation axis as the center of circle to ensure that the storage lid 4 can be smoothly rotated and opened, or the storage lid 4 can be slightly elastically opened by the storage lid 4, and then the storage lid 4 can be removed from the trimming body 1 by moving the storage lid 4 so that the lid stopper 48 does not abut against the inner wall of the trimming body 1, thereby facilitating the rotational opening of the storage lid 4 and the removal of the storage lid 4 and facilitating the cleaning of the storage cavity 13.

The hair clipping device of the embodiment of the present invention further includes a cover operating assembly 5, the cover operating assembly 5 including an operating member 51, a transmission member 53, and a locking member 52 provided with a locking projection 521; the operating member 51 and the lock member 52 are linearly slidably connected to the trimmer body 1, respectively. In one embodiment, the operating member 51 and the locking member 52 are slidably coupled in a straight line by engaging with a sidewall of a cavity (not shown) of the trimming body 1.

The transmission member 53 has a first transmission surface 531 and a second transmission surface 532, and an included angle is formed between the first transmission surface 531 and the second transmission surface 532.

One of the operating member 51 and the locking member 52 abuts against the first transmission surface 531, and the other abuts against the second transmission surface 532.

The locking protrusion 521 is inserted into the locking hole 41 through the manicuring body 1.

In the operation principle, when the storage cover 4 needs to be opened to clean the cut hairs in the storage cavity 13, the linear sliding operation member 51 (the operation member 51 is moved by hand through a portion exposed from the trimming body 1, which will be described later, or linearly moved by a power device such as a linear motor) is used, the operation member 51 abuts against the first transmission surface 531/the second transmission surface 532 to move the transmission member 53 substantially downward, the second transmission surface 532/the first transmission surface 531 abuts against the locking member 52 to linearly slide the locking member 52 until the locking protrusion 521 is moved out of the locking hole 41, and the storage cover 4 can be opened to clean the cut hairs in the storage cavity 13. Conversely, the storage cover 4 can be mounted on the trimming body 1 to close the storage cover 4. That is, the storage lid 4 can be opened and closed easily.

Meanwhile, the storage cover 4 does not need to be provided with an elastic arm with a U-shaped section, so that no protrusion or groove is formed on the outer wall of the storage cover 4, and the storage cover 4 has better hand feeling when being held.

The outer wall of the storage cover 4 substantially coincides with the outer wall of the trimming body 1. The storage cap 4 has a better feel when held.

The operating member 51 is exposed from the trimmer body 1. The manual operation operating piece 51 is easily slid straight.

One end of the operating member 51 is exposed from one end (i.e., the end cap 199) of the trimming body 1. The outer wall of the storage cover 4 has no protrusion or groove, so that the storage cover 4 has better hand feeling when being held.

The transmission member 53 is provided with a push-lid projection 533, and there is a portion where the push-lid projection 533 overlaps with the storage lid 4 as viewed in a direction in which the linear slide operation member 51 moves the transmission member 53 substantially downward. In the process that the linear sliding operation member 51 moves the transmission member 53 substantially downward, the second transmission surface 532/the first transmission surface 531 abuts against the locking member 52, so that the locking member 52 slides linearly until the locking protrusion 521 moves out of the locking hole 41, and the storage cover 4 can be opened, and at the same time, the cover pushing protrusion 533 moves substantially downward along with the transmission member 53 and abuts against the storage cover 4, so that the storage cover 4 protrudes from the trimming body 1, and the storage cover 4 can be opened and removed continuously.

When the storage lid 4 is closed (i.e. when the locking protrusion 521 is inserted into the locking hole 41 and attached to the top wall of the locking hole 41), a buffer gap 534 is formed between the cover pushing protrusion 533 and the storage lid 4. Compared with the technical scheme that the cover pushing projection 533 is attached to the storage cover 4, and a gap is formed between the locking projection 521 and the top wall of the locking hole 41, so that when the storage cover 4 is abutted by the cover pushing projection 533, the locking projection 521 is drawn out of the locking hole 41, and the storage cover 4 can smoothly protrude from the trimming body 1; among the above-mentioned technical scheme, locking protrusion 521 inserts locking hole 41 and laminates with the roof of locking hole 41, can ensure that storage lid 4 does not rock, can ensure simultaneously that storage lid 4 can be smoothly from pruning main part 1 protrusion.

The cover operating unit 5 further includes a return elastic member 54, and both ends of the return elastic member 54 are connected to the trimming body 1 and the operating member 51, respectively, and/or both ends of the return elastic member 54 are connected to the trimming body 1 and the locking member 52, respectively. The operating member 51 and/or the lock member 52 can be reset without manually resetting the operating member 51 and/or the lock member 52, facilitating the closing of the storage cover 4.
