A buckle block 221 matching the first locking groove 31 is fixed on a side of the knob 22 close to the face shell 20, that is, the buckle block 221 can be buckled into the first locking groove 31.

[0024] The bottom of the face shell 20 is fixedly connected to the bottom plate 40 by screws and other structures, and a push block 41 that can slide in translation and a button 42 that can be raised and lowered are provided between the face shell 20 and the bottom plate 40. The top of the push block 41 is provided with a first inclined surface 411 facing the face shell 20 and the button 42, and the side of the push block 41 is provided with a second inclined surface 412 facing away from the knob 22. A locking groove 413 is provided on the side of the push block close to the knob 22, and a third inclined surface 421 that is in close contact with the first inclined surface 411 is provided at the bottom of the button 42. The third inclined surface 421 faces the push block 41 and is parallel to the first inclined surface 411. A lock hook 43 matching the second locking groove 32 is provided on the push block 41, that is, the lock buckle can be buckled into the second locking groove 32. The bottom of the lock hook 43 close to one end of the knob 22 is an inclined guide surface structure, which can facilitate locking and buckling. A first spring perpendicular to the push block 41 is connected between the lock hook 43 and the face shell 20 44, a fourth inclined surface 431 is provided at the bottom of the lock hook 43, which is in close contact with the second inclined surface 412. The fourth inclined surface 431 is opposite to the second locking groove 32 and is parallel to the second inclined surface 412. A clutch block 45 is also provided on the push block 41, which is located on one side of the buckle seat 30. The clutch block 45 is located on one side of the lock hook 43. A second spring 46 perpendicular to the push block 41 is connected between the clutch block 45 and the face shell 20, that is, the lock hook 43 and the clutch block 45 can both translate perpendicular to the push block 41. A locking groove 451 is provided at the bottom of the clutch block 45, and a locking block 47 matching the locking groove 413 is slidably connected in the locking groove 451. The bottom of the locking block 47 protrudes from the bottom of the locking groove 451 to ensure that the locking block 47 can be inserted into the locking groove 413. A third spring 48 parallel to the second spring 46 is connected between the locking block 47 and the end wall of the locking groove 451.

[0025] The surface shell 20 is provided with a structure for installing a push block 41 , a button 42 , a lock hook 43 and a clutch block 45 , and the surface shell 20 is also provided with a press-release hole for making way for the button 42 .

[0026] When locking, the buckle block 221 is buckled in the first locking groove 31, and under the action of the first spring 44, the lock hook 43 is buckled in the second locking groove 32, the clutch block 45 is against one side of the buckle seat 30, the positioning block 47 is against one side of the push block 41, and the second spring 46 and the third spring 48 are both in a compressed state; when unlocking is required, the button 42 is pressed, and under the action of the third inclined surface 421 and the first inclined surface 411, the push block 41 moves away from the button 42 and retreats. In the process of the push block 41 retreating, the second inclined surface 412 and the first inclined surface 411 are pressed against the push block 41, and the second inclined surface 412 and the first inclined surface 411 are pressed against the push block 41. Under the action of the fourth inclined surface 431, the lock hook 43 is pushed away from the second locking groove 32 and the first spring 44 is compressed. When the push block 41 retreats to the position where the locking groove 413 faces the locking block 47, the locking block 47 is inserted into the locking groove 413 under the action of the third spring 48. At this time, the push block 41 stops moving due to being limited, and the lock hook 43 is always outside the second locking groove 32. The unlocking can be achieved by turning the knob 22 to make the buckle block 221 disengage from the first locking groove 31. After the buckle seat 30 is separated from the face shell 20, it is also separated from the cover 20. The clutch block 45 that loses its limit moves away from the push block 41 under the action of the second spring 46. Since the top of the locking block 47 is slidably connected to the locking slot 451, after the clutch block 45 translates a certain distance, one end of the locking block 47 away from the third spring 48 contacts the end wall of the locking slot 451. In the process of the clutch block 45 continuing to move away from the push block 41, the locking block 47 is driven to disengage from the locking groove 413, thereby releasing the limit on the push block 41. Under the action of the first spring 44, the lock The hook 43 is reset away from the push block 41, and the push block 41 moves towards the button 42 under the action of the second inclined surface 412 and the fourth inclined surface 431, and the button 42 rises and resets under the action of the first inclined surface 411 and the third inclined surface 421; when fastening again, the buckle seat 30 reaches one side of the knob 22, the buckling block 221 is inserted into the first locking groove 31, the first spring 44 is compressed and then restored, and the locking hook 43 is inserted into the second locking groove 32 to achieve locking. The buckling and locking action does not require the coordination of other actions to achieve, and the operation is simple and convenient.

[0027] In this embodiment, the cross-section of the snap block 221 is triangular, that is, the outer shape of the snap block 221 is a sideways V-shaped structure, which can ensure that the snap block 221 has sufficient avoidance space, and it is convenient for the snap block 221 to disengage from the first locking groove 31 when the knob 22 is swung.

[0028] In this embodiment, a first limiting plate 432 is fixed to the bottom of the locking hook 43. The first limiting plate 432 is located on the side of the push block 41 away from the knob 22. The first limiting plate 432 can effectively limit the position of the locking hook 43 to prevent the locking hook 43 from detaching from the face shell 20.

[0029] In this embodiment, a second limit plate 452 is fixed to the bottom of the clutch block 45. The second limit plate 452 is located on the side of the push block 41 away from the knob 22. The second limit plate 452 can effectively limit the position of the clutch block 45 to prevent the clutch block 45 from separating from the face shell 20.

[0030] In this embodiment, a fifth inclined surface 453 is provided at the bottom of the clutch block 45 near the knob 22, and the fifth inclined surface 453 faces away from the opposite shell 20 and the push block 41. Through the guiding effect of the fifth inclined surface 453, the smoothness of the action when buckling and locking can be effectively improved.
