[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] refer to Figure 1-6 As shown, the plum blossom lock unlocking tool proposed in this embodiment of the utility model includes an unlocking body, a pin, a fastener, and a reset structure.

[0026] The unlocking body 1 has a hollow column 11 at one end, and multiple sliding grooves 12 on the outer wall of the column 11. The other end of the unlocking body 1 has an internal thread 13. Multiple pins 2 are slidably arranged in the corresponding sliding grooves 12. Fasteners 3 are arranged between the unlocking body 1 and the column 11, and the fasteners 3 are sleeved on the column 11. The reset structure 4 has a boss 41, and the boss 41 has an external thread 42. The external thread 42 passes through the internal thread 13 so that the reset structure 4 can be movably arranged on the unlocking body 1, and the boss 41 resets the pins 2.

[0027] In other words, the length of the ejector pin 2 is the same as the length of the column 11, and the number of the slide grooves 12 is the same as the number of ejector pins 2, so that the ejector pins 2 are set one-to-one in the slide grooves 12. The reset structure 4 is detachably installed on the unlocking body 1 by means of a threaded connection. When the external thread 42 passes through the internal thread 13, the reset structure 4 is limited by the thread, so that it can be movably installed on the unlocking body 1. By pressing the reset structure 4, the reset structure 4 pushes the protruding ejector pin back into the slide groove 12 through the boss 41 to perform the reset.

[0028] As an example, the reset structure 4 is also provided with an annular groove 43.

[0029] As an example, the plum blossom lock picking tool also includes an elastic element 5, which is sleeved on the boss 41 and disposed in the annular groove 43.

[0030] It should be noted that when the user presses the reset structure 4, the state of the reset structure 4 is as follows: Figure 2As shown, the ejector pin 2 is in a reset state at this time, and the elastic element 5 provided in the annular groove 43 of the reset structure 4 has a buffering effect, which can absorb impact and vibration, thereby reducing damage to the equipment and structure. At the same time, it can provide a restoring force, so that the reset structure 4 can automatically return to its original position after being displaced; wherein, the elastic element 5 can be a spring.

[0031] As an example, fastener 3 is a rubber sleeve to ensure that the ejector pin will not fall off during sliding.

[0032] In other words, the rubber sleeve can fix or protect the ejector pin, ensuring that it will not fall off during use.

[0033] As an example, a first auxiliary arm 14 is provided on one side of the unlocking body 1, and a second auxiliary arm 15 is provided on the other side. The first auxiliary arm 14 and the second auxiliary arm 15 are detachably mounted on the unlocking body 1.

[0034] It should be noted that the first auxiliary arm 14 and the second auxiliary arm 15 are both perpendicular to the unlocking body 1; when using the plum blossom lock unlocking tool to rotate and unlock, the first auxiliary arm 14 and the second auxiliary arm 15 can be rotated to achieve easy rotation by using rotational force.

[0035] In addition, such as Figure 3 As shown, this application has seven pins. When the lock-picking tool is inserted into the plum blossom lock, because the upper pins inside the plum blossom lock are of varying lengths while the lower pins are of the same length, after the pin 2 is inserted into the lock body, the lower spring force is uniform. Since the depth of the lowest pin groove is limited, when the pin 2 of the lock-picking tool is greater than the spring force of the lock cylinder springs, when the lock-picking tool pushes the lock cylinder all the way down, the longer upper pins in the lock cylinder will push back the corresponding pin 1 of the lock-picking tool, while the shorter upper pins will not push back the corresponding pin 2. Therefore, multiple pins 2 may be pushed back by different lengths, such as... Figure 6 As shown, this causes multiple pins 2 to be pushed back to a state equivalent to the key of the plum blossom lock, at which point the plum blossom lock can be easily opened.

[0036] In addition, the method of unlocking a plum blossom lock using a tool includes: first, pressing the reset structure to reset multiple pins to align with the column body via the boss; next, aligning the reset column body with the plum blossom lock to be unlocked and inserting it into the keyhole; then, rotating the unlocking body to move the column body within the keyhole, causing multiple pins on the column body to be pushed back by the springs inside the plum blossom lock, forming multiple grooves that fit the plum blossom lock; finally, through the fitting column body, all the lower pins inside the plum blossom lock are pushed back into the lower cylinder, while the upper pins remain in the upper cylinder, thus completing the unlocking action.

[0037] In summary, in the embodiments of this utility model, the plum blossom lock unlocking tool includes an unlocking body, a pin, a fastener, and a reset structure. One end of the unlocking body has a hollow column with multiple grooves on its outer wall, and the other end has an internal thread. Multiple pins are slidably disposed within the grooves. Fasteners are disposed between the unlocking body and the column, and are sleeved on the column. The reset structure has a boss with an external thread, which passes through the internal thread to allow the reset structure to be movably disposed on the unlocking body, and the boss resets the pins. Thus, by slidably disposing each pin on a groove on the outer wall of the column, and by resetting the pins through the boss on the reset structure, all plum blossom locks to be unlocked can be quickly unlocked, improving the user experience.
