[0015] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0016] In the description of the present invention, it should be understood that the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of such features.

[0017] Furthermore, in this utility model, unless otherwise expressly specified or limited, terms such as "mounted" and "connected" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] In the present invention, up, down, left and right are descriptions of specific directions in actual use according to the drawings in the specification.

[0019] like Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment proposes an automatically unlockable marking tool, which mainly includes: a marking tool body, an unlocking key 6, a gear cover outer ring 4, a gear 5, a gear cover 2, a rivet 3 and a crank 1; the front end of the gear cover outer ring 4 of this embodiment is provided with a first hollow area for placing the unlocking key 6, and the first hollow area allows the unlocking key 6 to move back and forth, and a second hollow area for placing the gear cover 2 is provided on the gear cover outer ring 4, the lower end of the gear cover outer ring 4 is connected to the upper end of the marking tool body, and there is a space between the two for accommodating the gear 5 and the lower end of the gear cover 2. The outer periphery of the lower end of the gear cover 2 of this embodiment has a tooth-like structure, as shown in FIG. Figure 5 As shown, the tooth structure is composed of a long side and a short side. In order to cooperate with the tooth structure on the gear cover 2, a protrusion structure is provided at the rear end of the unlocking key 6, and the protrusion structure is adapted to the tooth structure on the gear cover 2.

[0020] like Figure 6 As shown, under the action of external force, the unlocking key 6 moves backward, causing its rear end to be stuck in the gear cover 2, thereby locking the gear cover 2. The gear cover 2 of this embodiment is fixedly connected to the gear 5. When the gear cover 2 is locked, the gear 5 is locked. Under the action of external force, the unlocking key 6 moves forward, causing its rear end to leave the gear cover 2, thereby unlocking the gear cover 2, i.e., unlocking the gear 5, and marking is performed at this moment. The crank 1 is movably connected to one side of the upper end of the gear cover 2 by the rivet 3. When it needs to be used, the crank 1 is opened, the gear cover 2 is unlocked, and the crank 1 is turned, and the scriber body comes out to perform marking. As shown Figure 6 As shown, the present invention realizes that the unlocking key can automatically detach from the gear cover when the gear cover is rotated to reel in the line through the angle design of the unlocking key and the gear cover, thereby effectively protecting the unlocking mechanism and ensuring the reliability of the locking mechanism.

[0021] like Figure 3As shown, the main body of the scriber includes: an upper cover 7, a wire reel 8, a lower cover 10 and a powder adding cover 9. The upper cover 7 and the lower cover 10 are connected to form a chamber for placing the wire reel 8, and the powder adding cover 9 is located at the front end of the chamber; the wire reel 8 is located in the main body of the scriber, and the wire reel 8 is connected to the gear 5 and is controlled by the gear 5; the wire on the wire reel 8 extends out of the powder adding cover 9 and is connected to the hook. When in use, the hook is pulled to pull the wire covered with powder out from the inside of the main body of the scriber to complete the marking.
