The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 2-5, an unlocking tool for an AB reverse slot lock according to an embodiment of the present utility model includes a key 1 and a tinfoil 2. When the foam is specifically used, the foam may be tin paper or foam sponge, and the tin paper is taken as an example for description.

Specifically, the key 1 has a key handle 12 and a key lever 11, the key lever 11 is connected with the key handle 12, the key lever 11 has a plate body 111 suitable for being inserted into a lock hole of a lock cylinder, a first straight groove 112 and a second straight groove 113 are arranged on the upper surface of the plate body 111 along the length direction of the plate body, the first straight groove 112 and the second straight groove 113 are arranged at intervals along the width direction of the plate body 111, the first straight groove 112 and the second straight groove 113 are suitable for being in one-to-one guide fit with two second ribs 32 in the lock hole, a third straight groove 114 is arranged on the lower surface of the plate body 111 along the length direction of the plate body, a groove 115 is formed by downwards concave bottom surface of the third straight groove 114, two guide grooves 116 are arranged between the third straight groove 114 and the insertion end of the plate body 111, and the two guide grooves 116 are suitable for being in one-to-one guide fit with the two first ribs 31 in the lock hole. It will be appreciated that the two guide grooves 116 are spaced apart such that there are ribs between the two guide grooves 116 that curve with the uneven drop of the third straight groove 114. The tinfoil 2 is adapted to fit into the recess 115 such that when the plate 111 is inserted into the lock hole and the key handle 12 is shaken, the recess 115 forces the tinfoil 2 to push the pins of the bottom surface of the lock cylinder to the unlocked position. It can be understood that the tinfoil 2 has elasticity, when the key rod 11 is inserted into the lock hole, the tinfoil 2 is positioned between the key rod 11 and the marble, and the material of the tinfoil can be utilized to copy the tooth patterns of the marble at different positions by elasticity when shaking, and the tooth patterns are forcefully opened after being copied to a certain degree, so that the lock cylinder is unlocked. Wherein the tinfoil 2 can be trimmed to match the shape of the recess 115.

Therefore, according to the unlocking tool of the AB anti-slot lock, when the AB anti-slot lock on the door is broken and disassembled, the high-arch tinfoil strips 2 are placed into the grooves 115, wherein the tinfoil strips 2 can be stuck in the grooves 115 by matched glue, then the tin strips are inserted into the lock holes of the lock cylinder, the key handle 12 is operated to enable the key rod 11 to shake left and right for several times, and then single-row marble in the lock holes can be jacked to the unlocking position, so that the lock cylinder is unlocked, the speed of breaking and disassembling the lock is improved, the time is shortened, and the generated noise is small. In addition, the first straight groove 112 and the second straight groove 113 are in guiding fit with the two second ribs 32 in the lock hole, so that the key can be inserted into the lock hole to be positioned accurately, and the two guiding grooves 116 and the two first ribs 31 are in guiding fit, so that the tinfoil 2 in the groove 115 can act on the marble to be positioned accurately.

For the plate body 111, the center line of the plate body 111 along the length direction thereof may be divided into a first region in which the first straight groove 112 and the second straight groove 113 are located and a second region in which the third straight groove 114 is located. It will be appreciated that the straight groove on the upper surface of the plate 111 occupies the left half and the straight groove on the lower surface of the plate 111 occupies the right half, so that the straight groove or groove is used to correspond to the rib and pin design in the lock hole.

For the lower surface of the plate 111, two guiding grooves 116 are arranged between the third straight groove 114 and the insertion end of the plate 111, and the two guiding grooves 116 are suitable for guiding and matching with the two first ribs 33 in the lock hole in a one-to-one correspondence manner. It can be understood that the first ribs 31 are provided on two sides of the marble, so that the tin foil 2 in the groove 115 can be located right above the marble 31, and the first ribs 31 on two sides of the marble can be inserted into the two guide grooves 116 by the arrangement of the two guide grooves 116, so that the two first ribs 31 are guided into the third straight groove 114, and the marble 31 can be corresponding to the tin foil corresponding to the groove 115.

More specifically, the two guide grooves 116 are arranged at intervals and are located at two sides of the groove 115 in a one-to-one correspondence, a protrusion 117 is formed between the two guide grooves 116, the protrusion 117 is engaged with the groove 115, and when the plate body 111 is inserted into the lock hole by the protrusion 117, the plate body 111 can press down the marble, so that the tinfoil 2 in the groove 115 can be smoothly located below the marble.

The insertion end of the plate 111 has an inclined surface 118, and the inclined surface 118 is inclined inward from the upper surface to the lower surface of the plate 111. Thus, the plate 111 is easily inserted into the lock hole by providing the inclined surface 118.

For the spoon handle 12, the spoon handle 12 is provided with a first handle body 121, a second handle body 122 and a third handle body 123, one end of the first handle body 121 is connected with the spoon rod 11, the other end is connected with the second handle body 122, the second handle body 122 is connected with the third handle body 123, the first handle body 121, the second handle body 122 and the third handle body 123 are all cylinders, and the diameter of the first handle body 121 is smaller than that of the second handle body 122 and smaller than that of the third handle body 123. Thus, by using the tapered handle body as the spoon handle 12, the weight of the spoon handle 12 can be reduced, and the spoon handle 12 has enough supporting force.

Further, the second handle 122 and the third handle 123 are engaged by the vertebral body 124. Thus, by the connection of the vertebral bodies 124, sufficient support is provided between adjacent handle bodies.

Specifically, the key lever 11 is welded to the first handle body 121, and the first handle body 121, the second handle body 122, the cone 124, and the third handle body 123 are integrally formed.

In addition, the third handle 123 is provided with a through channel 1231, and the channel 1231 is adapted to be inserted into the operating rod 13 for holding. When the operating rod 13 is inserted into the third handle body 123, the handle 12 can be held and rotated, so as to rotate the key rod 11. When the operating rod 13 is inserted into the third handle 123, the operating rod 13 and the spoon handle 12 form a T-shaped structure.

When the portable lock is required to be carried, the operating rod 13 is separated from the key handle 12, so that the lock unlocking tool is convenient to be put into a bag or a box for carrying. When the lock is to be broken, the operation lever 13 is inserted into the passage 1231.

Wherein, the channel 1231 is provided with a protrusion 1232 adapted to abut against the lever 13, and the protrusion 1232 has a certain friction force on the lever 13, so that the lever 13 will not slip in the channel 1231 or separate from the spoon handle 12.
