As shown in fig. 1 to 4, an unlocking tool for a linear 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 rod 11, the key rod 11 is connected with the key handle 12, the key rod 11 is provided with a plate body 111 which is suitable for being inserted into a lock hole of a lock cylinder, the upper surface of the plate body 111 is concave to form a first straight groove 112, the first straight groove 112 extends along the length direction of the plate body 111, the bottom surface of the first straight groove 112 is provided with a protrusion 113 and a groove 114, the protrusion 113 and the groove 114 are positioned on the center line of the bottom surface of the first straight groove 112, the protrusion 113 is provided with a first inclined surface 1131 and a second inclined surface 1132 which are connected, the first inclined surface 1131 is connected with the insertion end of the plate body 111, the second inclined surface 1132 is connected with one end of the groove 114, the lower surface of the plate body 111 is concave to form a second straight groove 115, and the second straight groove 115 is suitable for being in guiding fit with ribs in the lock hole. The protrusion 113 is located at the insertion end of the first straight groove 112, and when the protrusion 113 is inserted into the lock hole, it will act corresponding to the innermost steel ball of the lock hole, and the protrusion 113 has a first inclined surface 1131 and a second inclined surface 1132, so that the first inclined surface 1131 engages with the insertion end of the plate 111, and the second inclined surface 1132 engages with one end of the groove 114, so that the protrusion 113 can be quickly brushed to pull the marble during insertion into the lock hole, and the marble is dislocated. The location of the recess 114 then corresponds to the action of the pin.

The tinfoil 2 is suitable for being embedded into the first 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 tinfoil 2 to push the through steel ball in the lock cylinder to the unlocking position, and the groove 114 drives the tinfoil 2 to push the marble in the lock cylinder to the unlocking position.

Therefore, according to the unlocking tool for the linear lock, when the linear lock on the door or window is broken and disassembled, the thick tinfoil strip is placed into the first 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 subjected to left and right swinging, repeated operation is performed, and the through steel ball and the marble in the lock cylinder are propped against the unlocking position by utilizing the soft and hard matching of the groove 114 and the protrusion 113 and the tinfoil 2, so that the lock of 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 second straight groove 115 and the ribs in the lock hole are in guiding fit to rapidly position the key in the lock hole, so that the tinfoil 2 is precisely positioned below the marble.

For the protrusion 113, the protrusion 113 is located at the center line of the first straight groove 112, the first inclined surface 1131 of the protrusion 113 is inclined upwards from the insertion end of the plate 111 into the first straight groove 112, and the second inclined surface 1132 is inclined downwards towards the first straight groove 112, so that the protrusion 113 is triangular, and the protrusion 113 is convenient to pull and misplacement of the marble brush in the lock hole. The first inclined surface 1131 and the second inclined surface 1132 may be connected by a facet.

For the groove 114, the groove 114 has a first arc-shaped groove 1141, a second arc-shaped groove 1142 and a flat groove 1143, wherein one end of the first arc-shaped groove 1141 is engaged with the first inclined surface 1131, the other end is engaged with the flat groove 1143, and one end of the second arc-shaped groove 1142 is engaged with the flat groove 1143.
