Referring to fig. 2 to 6, an embodiment of the present utility model provides an unlocking tool for an AB band edge lock, which comprises an insertion portion 100 and a rotation portion 200 connected to each other.

Specifically, the insertion portion 100 has a flat plate shape adapted to be inserted into the lock hole. A first slot 110 is formed in the front side of the insertion portion 100, and the first slot 110 is disposed along the longitudinal direction of the insertion portion 100. Specifically, the first slot 110 has a rectangular shape, and a length thereof extends from one end of the insertion portion 100 to the other end along a length direction of the insertion portion 100. And, the bottom surface of the first slot 110 is recessed downward to form a straight slot 120, and the straight slot 120 extends along the length direction of the insertion portion 100. Specifically, one end of the straight groove 120 is located at an end of the first slot 110 away from the rotating portion 200, and the other end extends to a certain length along the length direction of the inserting portion 100. And the depth of the straight groove 120 is gradually increased from both ends to the middle thereof to form a certain arc. The edge of the other side of the front surface of the insertion portion 100 has a first cambered surface 130, and the first cambered surface 130 extends along the length direction of the insertion portion 100 and has an opening facing outwards, so as to avoid the structure in the lock hole.

A second slot 140 is formed on one side of the back surface of the insertion portion 100, the second slot 140 is located in an oblique diagonal direction of the first slot 110, and the second slot 140 is disposed along a length direction of the insertion portion 100. Specifically, the second slot 140 has a rectangular shape, and a length thereof extends from one end of the insertion portion 100 to the other end thereof along the direction of the insertion portion 100. And, the bottom flue gas length direction of the second slot 140 is provided with a parting bead 150, the parting bead 150 is located in the middle of the second slot 140, and the height of the parting bead 150 is equal to the depth of the second slot 140. The other side edge of the back surface of the insertion part 100 has a second arc surface 160, and the second arc surface 160 extends along the direction of the insertion part 100 and is provided with an opening facing outwards.

The rotating portion 200 has a rod shape to facilitate gripping. Therefore, the first slot 110, the straight slot 120, the first cambered surface 130, the second slot 140, the parting bead 150 and the second cambered surface 160 can be matched with the lock hole of the AB belt edge lock so as to facilitate insertion. In the in-service use, when breaking open the AB tape edge lock, can put into the slot with elastic material (e.g. tinfoil, foam sponge etc.), insert portion 100 again in the lockhole of AB tape edge lock, through operating rotation portion 200 for insert portion 100 rotates or rocks, as if the operation is in order to make the pellet shot in the lockhole radial movement to the unblock position in order to realize the unblock, thereby can improve broken open the efficiency of AB tape edge lock, and the noise that produces is less.

In one embodiment of the present utility model, the front surface of the insertion portion 100, which is far away from the rotation portion 200, has a sloped guide surface, which can reduce the thickness of the end of the insertion portion 100, and the smaller thickness can enable the portion inserted into the locking hole to move the pins radially a certain distance during the insertion of the locking hole, so that the subsequent portion can be inserted smoothly.

In one embodiment, the rear surface of the insertion portion 100 is recessed downward from the end of the rotation portion 200 to form a step. So that the thickness of the insertion portion 100 at an end remote from the rotation portion 200 can be further reduced, facilitating insertion of the insertion portion 100 into the locking hole. It should be appreciated that the step is low in height, e.g., less than 1mm, to ensure structural strength of the insert 100.

In an embodiment, the rotating portion 200 includes a first rod portion 210, a second rod portion 220 and a third rod portion 230 sequentially connected, wherein one end of the first rod portion 210 is connected to the insertion portion 100, the other end is connected to the second rod portion 220, and the second rod portion 220 is connected to the third rod portion 230. And, the diameter of the first shaft portion 210 is smaller than the diameter of the second shaft portion 220, and the diameter of the second shaft portion 220 is smaller than the diameter of the third shaft portion 230. Alternatively, the first, second and third stem portions 210, 220, 230 may be integrally formed structures. Thus, by the arrangement of the first, second and third lever portions 210, 220 and 230 and the arrangement of the different diameters, the structural strength of the rotation portion 200 can be ensured while also being easy to hold.

In an embodiment, the unlocking tool further includes a holding rod 300, and a first insertion hole 231 into which the holding rod 300 is inserted is formed in a radial direction of an end of the third rod portion 230, which is far from the second rod portion 220. In actual use, the user can insert the grip lever 300 into the first insertion hole 231 to have a T shape so as to exert a force when breaking the door lock.

Further, the inner wall of the first insertion hole 231 is provided with a protrusion so that when the grip lever 300 is inserted into the first insertion hole 231, the side wall of the grip lever 300 may be abutted to increase friction with the grip lever 300. The grip lever 300 can be prevented from slipping in the first insertion hole 231 or from being separated from the third lever portion 230. In one example, the protrusion may be hemispherical.

In an embodiment, the third rod portion 230 is provided with a second jack 232 along an axial direction thereof, the second jack 232 is identical to the first jack 231, the second jack 232 may be square, and the second jack 232 may be used for inserting and clamping other auxiliary tools to improve an application range of the unlocking tool.
