[0024] See also Figure 1 、 2 A pair of scissors with a locking mechanism includes a first scissor blade 12, a second scissor blade 16, a locking mechanism, a rotating connecting block 5, a buckle 6 and a pivot shaft 11. The first scissor blade 12 and the second scissor blade 16 are rotatably connected together by the pivot shaft 11. The first scissor blade 12 and the second scissor blade 16 are respectively provided with a first handle 17 and a second handle 13. The rotating connecting block 5 is arranged on the first handle 17, and the buckle 6 is arranged on the second handle 13. The locking mechanism is rotatably installed on the rotating connecting block 5, and the buckle 6 can be snapped into the locking mechanism.

[0025] The locking mechanism includes a locking upper cover 2, a locking lower cover 7, a spring wave ball 4, a female nail 3 and a sub-nail 8. The locking upper cover 2 and the locking lower cover 7 are provided with two through holes 15, and the rotating connecting block 5 is provided with a rotating shaft hole 14. The locking upper cover 2 is located above the rotating connecting block 5, and the locking lower cover 7 is located below the rotating connecting block 5. The locking upper cover 2 and the locking lower cover 7 are connected together by the female nail 3 and the sub-nail 8 passing through the through hole 15. The through hole 15 and the rotating shaft hole 14 of the locking upper cover 2 and the locking lower cover 7 close to the rotating connecting block 5 are on the same axial line; the female nail 3 close to the side of the rotating connecting block 5 passes through the through hole 15 and the rotating shaft hole 14 and is connected to the sub-nail 8 together; the female nail 3 close to the side of the rotating connecting block 5 locks the rotating axis of the locking mechanism, so that the locking mechanism can rotate.

[0026] In this embodiment, the female nail 3 and the male nail 8 are connected together by threaded connection.

[0027] The lock lower cover 7 is provided with a snap-fit ​​groove 9 and a ball groove 10. The spring ball 4 is arranged in the ball groove 10. The snap-fit ​​groove 9 can be inserted into the snap-fit ​​groove 9. The ball groove 10 is located on one side of the snap-fit ​​groove 9. The side wall of the snap-fit ​​groove 9 is provided with a circular hole connected to the ball groove 10, so that the ball of the spring ball 4 can extend into the snap-fit ​​groove 9; when the snap-fit ​​groove 9 is in the snap-fit ​​groove 9, the spring ball 4 can press against the snap-fit ​​groove 6, so that the snap-fit ​​6 is in a locked state.

[0028] The lock upper cover 2 and the lock lower cover 7 are both provided with a decorative cover 1, which is embedded in the lock upper cover 2 and the lock lower cover 7 by snapping; the decorative cover 1 can cover the mother nail 3 and the child nail 8.

[0029] In this embodiment, in order to further improve the locking force of the buckle 6, a spherical groove is provided on the side of the buckle 6 close to the spring ball 4. The spring ball 4 can be used in conjunction with the spherical groove, so that the buckle 6 can be locked more tightly.

[0030] like Figure 2 As shown, in order to further improve the fit between the locking mechanism and the buckle 6, a limit block 18 is provided on the first handle 17 and the second handle 13. When the two limit blocks 18 are in contact, the first scissor blade 12 and the second scissor blade 16 of the entire scissors are in a closed state, and the buckle 6 can be just snapped into the snap groove 9.

[0031] In order to improve the comfort of use, in this embodiment, the first handle 17 and the second handle 13 are both made of rubber or plastic material.

[0032] In order to further improve the use effect, the buckle 6 and the rotating connecting block 5 are made of the same material as the first scissor blade 12, and are welded to the second scissor blade 16 and the first scissor blade 12 respectively; the buckle 6 and the rotating connecting block 5 can pass through the first handle 17 and the second handle 13.

[0033] During use, when the scissors need to be locked, just close the scissors first, and then rotate the locking mechanism so that the buckle 6 can be inserted into the locking groove 9 in the locking mechanism. At this time, the spring ball 4 can press the buckle 6 tightly so that the buckle 6 will not fall out of the locking groove 9; conversely, just rotate the locking mechanism in the opposite direction so that the buckle 6 can fall out of the locking groove 9, thereby achieving unlocking.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
