The protective cover 4 is slidably connected to the fixing sleeve 5 through the movable block 7. A rubber pad is installed on the top of the protective cover 4 so that when the protective cover 4 moves downward, the movable block 7 can be driven to slide inside the fixing sleeve 5, and the movable block 7 can squeeze the reset spring 6 when it moves.

[0039] Embodiment 2:

[0040] On the basis of the above-mentioned first embodiment, when the protective cover 4 is received in the fixing sleeve 5, it is necessary to limit the protective cover 4 to prevent the protective cover 4 from moving out of the fixing sleeve 5 and affecting the use of the shaving head 3, so the following structure is provided.

[0041] See also Figure 1-Figure 5 Two grooves 10 are also provided on the upper part of the interior of the fixed sleeve 5, and a spring 13 is installed inside the groove 10. One end of the spring 13 is connected to a card block 11, and the card block 11 is adapted to the card slot 14. When the card block 11 moves toward the direction of the protective cover 4, it will stretch the spring 13, which is convenient for the subsequent driving of the card block 11 to reset and move. A movable rod 12 that penetrates the outside of the fixed sleeve 5 is installed on one side of the card block 11. Card slots 14 are provided on the upper part of both sides of the protective cover 4. When the movable rod 12 moves, it will drive the card block 11 to move, so that the card block 11 is stuck into the inside of the card slot 14, so as to limit the protective cover 4.

[0042] Embodiment three:

[0043] On the basis of the above-mentioned second embodiment, it is necessary to limit the movable rod 12 to prevent the movable rod 12 from arbitrarily driving the block 11 to move. Therefore, the following structure is provided to achieve the purpose of limiting the movable rod 12.

[0044] See also Figure 1-Figure 4 The outer wall of the fixed sleeve 5 is sleeved with a rotating sleeve 8, and a limiting ring 9 is installed on the rotating sleeve 8. When the rotating sleeve 8 rotates, it will drive the limiting ring 9 to move. When the limiting ring 9 contacts the movable rod 12, the limiting ring 9 can limit the movable rod 12. Threads are provided on the upper part of the outer wall of the fixed sleeve 5 and the inner wall of the rotating sleeve 8. The rotating sleeve 8 is threadedly connected to the fixed sleeve 5. The setting of the thread facilitates the rotation of the rotating sleeve 8, and then the position of the rotating sleeve 8 can be conveniently adjusted.

[0045] The working principle of the utility model is as follows: first, when the hair clipper is used, the limiting plate 18 can be rotated upwards so that the limiting plate is no longer in contact with the shaving head end 3, and then the protective cover 4 is pressed downwards so that the protective cover 4 is moved into the fixing sleeve 5, and at the same time, the limiting plate 18 is stored in the storage slot 15, and when the clamping block 11 is aligned with the clamping slot 14, the movable rod 12 is pressed so that the movable rod 12 drives the clamping block 11 to move into the clamping slot 14, so as to limit the protective cover 4, and at the same time, the rotating sleeve 8 is rotated so that the limiting ring 9 moves, and the limiting ring 9 contacts the movable rod 12, so as to achieve the purpose of limiting the movable rod 12, so that the shaving head end 3 is no longer blocked by the protective cover 4, and the user can use it;

[0046] When it is necessary to protect the shaving head end 3, the rotating sleeve 8 can be reversed to reset the rotating sleeve and drive the limiting ring 9 to reset, and the limiting ring 9 is no longer in contact with the movable rod 12. At this time, the spring 13 is stretched and drives the block 11 to move, so that the block 11 is moved out of the slot 14. At this time, the block 11 no longer limits the protective cover 4. Then the protective cover 4 moves up and resets to block the shaving head end 3, thereby achieving the purpose of shielding and protecting the shaving head end 3. At the same time, the limiting plate 18 is no longer squeezed, the torsion spring 17 recovers and drives the movable shaft 16 to reset and rotate, and then drives the limiting plate 18 to reset and rotate, so that the limiting plate 18 is in contact with the shaving head end 3. When the hair clippers accidentally fall to the ground , since the setting of the protective cover 4 can achieve the purpose of protecting the shaving head end 3, at the same time, if the protective cover 4 falls downward to the ground, the protective cover 4 first contacts the ground, and then moves and squeezes the reset spring 6, so that the reset spring 6 is compressed, so as to buffer the impact force generated by the impact of the protective cover 4, so as to protect the shaving head end 3, and when the protective cover 4 moves downward, the limiting plate 18 contacts the shaving head end 3, so that the limiting plate 18 rotates, and the torsion spring 17 can make the limiting plate 18 tightly contact with the shaving head end 3, avoiding the separation of the limiting plate 18 and the shaving head end 3, and the setting of the limiting plate 18 can avoid the direct contact between the shaving head end 3 and the ground.
