The protrusion 113 is located at the insertion end of the straight groove 112, and when inserted into the lock hole, it will act corresponding to the innermost through bead of the lock hole, the position of the groove 114 will act corresponding to the marble with the true and false groove, and the position of the convex strip 115 will act corresponding to the outer column. The lower surface of the plate 111 is an arc surface, so that the plate 111 can be matched with a crescent-shaped lock hole.

The elastic tinfoil 2 is suitable for being embedded into the straight groove 112, so that when the plate body 111 is inserted into the lock hole and the key handle is shaken, the protrusion 113 drives the elastic tinfoil 2 to push the through beads in the lock cylinder to the unlocking position, the groove 114 drives the elastic tinfoil 2 to push the marbles with true and false grooves in the lock cylinder to the unlocking position, and the convex strip 115 drives the elastic tinfoil 2 to push the outer columns in the lock cylinder to the unlocking position.

Therefore, according to the unlocking tool for the crescent lock, when the crescent lock on a door or a window is broken and disassembled, the elastic tin paper with high arching property is put into the straight groove 112, then the lock hole of the lock cylinder is inserted, the key handle 12 is operated to enable the key rod 11 to swing up and down, then the key rod is swung left and right, repeated operation is carried out, and through the soft and hard matching of the convex strips 115, the grooves 114 and the protrusions 113 and the elastic tin paper 2, the through beads, the true and false groove beads and the outer columns in the lock cylinder are propped against the unlocking position, so that the lock of the lock cylinder is released, the speed of breaking and disassembling the lock is improved, the time is shortened, and the generated noise is small.

For the protrusion 113, the protrusion 113 is located at the center line of the straight groove 112, and the guide groove 116 is defined between the protrusion 113 and the inner wall of the straight groove 112. It will be appreciated that the protrusion 113 is located at the insertion end of the straight slot 112, and when it is inserted into the lock hole, it will act corresponding to the innermost through bead of the lock hole, and during the process of inserting the lock hole, the two guide slots 116 cooperate with the two teeth on the lock hole, so as to act as guides for the process of inserting the plate 111 into the lock hole, facilitating the rapid insertion of the key 1, and enabling the elastic tinfoil 2 of the straight slot 112 to be precisely aligned with the beads in the lock hole.

As for the grooves 114, the grooves 114 are arc-shaped along the length direction of the plate body 111. It will be appreciated that the grooves 114 are arcuate grooves that allow the grooves 114 to act on the marbles of the true and false grooves in different positions. Wherein, the position of the engagement of the groove 114 and the convex strip 115 is not more than half of the position of the straight groove 112.

For the ridge 115, the heights of the ridge 115 and the protrusion 113 are both lower than the depth of the straight groove 112. The top surface of the ridge 115 may be an inclined surface.

In addition, the insertion end of the plate body 111 has an inclined surface 117, and the inclined surface 117 is provided obliquely inward from the lower surface to the upper surface of the plate body 111. Thus, the plate 111 is easily inserted into the lock hole by providing the inclined surface 117.

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. Therefore, through the connection of the vertebral bodies, enough supporting force is provided between the 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.
