With this structure, the flip cover can be stably placed on the cutter opening, preventing the flip cover from being accidentally rotated open.

[0009] Preferably, both the top and bottom ends of the snap-fit ​​connector are provided with clearance surfaces, which are inclined or curved surfaces. These clearance surfaces are used to avoid obstructing the inner wall of the lever opening located above the snap-fit ​​interface. With this structure, when the snap-fit ​​connector is snapped into the corresponding snap-fit ​​interface, simply press the flip cover lightly, and the bottom of the snap-fit ​​connector will slide downwards to allow the snap-fit ​​connector to smoothly enter the snap-fit ​​interface; to open the flip cover, simply pull the flip cover lightly, and the top of the snap-fit ​​connector will slide upwards to allow the snap-fit ​​connector to smoothly exit the snap-fit ​​interface, making the operation simple and convenient.

[0010] Preferably, the top of the inner sidewall of the lever opening is provided with a first opening groove, which is opposite to the sidewall located at the front or side of the flip cover. With this structure, it is convenient to insert a finger into the first opening groove and make contact with the sidewall of the flip cover, and then smoothly open the flip cover under the action of friction.

[0011] Preferably, the side wall of the flip cover is provided with a second opening groove opposite to the first opening groove. With this structure, it is convenient to insert a finger into the first opening groove and hook it into the second opening groove of the flip cover, and then gently pull the flip cover to open it smoothly.

[0012] Preferably, the flip cover mounting section further includes a stepped surface on the inner wall of the lever opening, the stepped surface supporting the front end and / or the two sides of the flip cover. This structure allows the flip cover within the mounting section to be held at the height of the stepped surface, facilitating easy finger access to the side wall of the flip cover for smooth opening, and preventing the flip cover from becoming difficult to open when rotated to the bottom of the mounting section.
