The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0024] 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 accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, 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.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Reference below Figure 1 and Figure 2 , the implementation of the unlocking tool for the springless blade lock proposed in an embodiment of the present invention is described in detail.

[0027] The unlocking tool for a springless blade lock according to an embodiment of the present invention comprises:

[0028] The rod body 10 can be inserted into the springless blade lock cylinder. The rod body 10 is provided with two opposite sliding grooves 101. The side of each sliding groove 101 is provided with a notch 102 communicating with the sliding groove 101, and a slope 103 is provided at the notch 102;

[0029] The slides 20 are slidable within the slots 101 . Each slide 20 has a protrusion 201 at the corresponding notch 102 . The slide 20 can adjust the position of the protrusion 201 at the notch 102 by sliding within the slots 101 , thereby forming different concave-convex combinations to match the different arrangements of the blades in the springless blade lock.

[0030] A fixing member 30 for fixing the slide 20 after the position is adjusted;

[0031] A handle 40 with a vibration member is provided, and the handle 40 is connected to the rod body 10 . The vibration member can vibrate the rod body 10 and the protrusion 201 , and the springless blade lock can be unlocked by cooperating with the twisting of the handle 40 .

[0032] That is to say, the inclined surface 103 at the notch 102 of the rod body 10 is equivalent to the concave part on the key of the springless blade lock, and the protrusion 201 on the slide 20 is equivalent to the protrusion of the key. The sliding setting of the slide 20 can adjust the position of the protrusion 201 at the notch 102, so as to match the various arrangements and combinations of the blades of the lock core. After adjusting the position of the slide 20, the slide 20 is fixed by the fixing member 30. When the vibration part of the handle 40 vibrates, it can drive the vibration of the rod body 10 and the slide 20. Through the torsion and vibration of the handle 40, the notches of the blades in the lock core can be quickly rotated to the same direction. The limit pin on one side of the lock core can enter the notch, and the entire lock core can be rotated relative to the lock body. The rotation of the lock core can make the steel ball move in the radial direction of the lock, thereby disengaging the steel ball from the slot of the lock beam, and then pulling out the lock beam can complete the unlocking. Among them, the sliding position of the slide 20 can be pre-positioned by marking or limiting, and then fixed by the fixing member 30. The fixing member 30 can be pressed against the rod body 10 from both sides by clamping or locking. The two notches 102 are diagonally arranged relative to the cross section of the rod body 10. The two inclined surfaces 103 can be parallel. The protrusion 201 can be formed by the slide 20 being concave at a position adjacent to the protrusion 201, so that the concave part can form an avoidance in the notch 102. The vibration member can be externally connected to the handle 40 or built into the handle 40. The vibration member can adopt an existing structure.

[0033] Thus, through the sliding cooperation between the rod body 10 and the slide 20, the relative position of the protrusion 201 of the slide 20 and the notch 102 of the rod body 10 can be adjusted, thereby forming a change in the tooth pattern to match the rotation of different combinations of blades. Then, through the vibration of the handle 40, the protrusion 201 of the rod body 10 and the slide 20 can be vibrated, so that the notches 102 of the blades at different positions can be quickly rotated to the same direction, thereby rotating the lock core to unlock. The unlocking tool of the springless blade lock has a simple structure, can be adapted to various types of springless blade locks, is easy to operate, and has high unlocking efficiency.

[0034] Optionally, each slide 20 is provided with an adjustment portion 202 extending from the rod body 10 along the side of the sliding direction. The adjustment portion 202 is adapted to adjust the sliding position of the slide 20. It is understood that the provision of the adjustment portion 202 facilitates manual adjustment of the position of the slide 20, thereby adjusting the position of the protrusion 201 to match different blade combinations. The adjustment portion 202 can protrude in the same direction as the protrusion 201 of the corresponding slide 20, so that the slide 20 is L-shaped overall.

[0035] Furthermore, the rod body 10 is provided with a limiting groove 104 capable of limiting each adjustment portion 202. It can be understood that the limiting groove 104 is provided to limit the sliding range of the adjustment portion 202, thereby limiting the sliding position of the slide 20. When both slides 20 are in contact with the rear groove wall of the limiting groove 104, the unlocking tool is adjusted to a 1+1 combination mode, and the 1+1 combination springless blade lock can be opened by vibrating and twisting the handle 40. When both slides 20 are in contact with the front groove wall of the limiting groove 104, the unlocking tool is adjusted to a 3+3 combination mode. When the two slides 20 are located in the middle position between the front groove wall and the rear groove wall, the unlocking tool is adjusted to a 2+2 combination mode.

[0036] Optionally, the fixing member 30 includes a base 301 and a screw 302 provided on the base 301. The base 301 is sleeved on the rod 10. When the screw 302 is tightened, the slide 20 can be pressed against the rod 10 to fix the adjusted slide 20. It can be understood that by sleeved on the top rod, the two slides 20 can be simultaneously restricted in the chute 101, so that the slide 20 can only move along the sliding direction of the chute 101. The slide 20 is then tightened against the rod 10 by the screw 302, thereby fixing the slide 20. The screw 302 can fix the slide 20 from the two width surfaces of the slide 20 or from the thickness surface of the slide 20. The cap of the screw 302 is provided with anti-slip grooves.

[0037] Furthermore, the rod body 10 is provided with an open opening 105 that communicates with the side of each slide groove 101. The open opening 105 can simultaneously expose the thickness surface of each slide 20. The screw 302 can contact the thickness surface of each slide 20 through the open opening 105 to fix each slide 20 after the position is adjusted. It can be understood that by exposing the thickness surface of each slide 20 through the open opening 105, it is convenient to fix and release the two slides 20 with a single screw 302, thereby facilitating the rapid adjustment and locking of the position of the slide 20.

[0038] Furthermore, each slide 20 is provided with a positioning groove 203 on its thickness surface, and the screw 302 can be synchronously abutted against each positioning groove 203 to limit the sliding position of the slide 20. It can be understood that the positioning grooves 203 can quickly fix the two slides 20 in the 2+2 combination position, thereby achieving rapid positioning of the slide 20. Of course, the number of positioning grooves 203 on each slide 20 can also be set to three, with the three positioning grooves 203 corresponding to the combination positions 1, 2, and 3 respectively.

[0039] Optionally, the handle 40 is further connected to an auxiliary rod 401, which is arranged along the radial direction of the handle 40. It can be understood that the provision of the auxiliary rod 401 facilitates the user's hand force, thereby facilitating the twisting of the entire lock picking tool. The auxiliary rod 401 can be connected to the handle 40 via a thread, and there can be two auxiliary rods 401, with the two auxiliary rods 401 and the handle 40 forming a cross-shaped structure.

[0040] Optionally, the handle 40 defines a hollow accommodating cavity, in which the vibrating member is disposed. The free end of the handle 40 is provided with an end cap 402, on which a button 403 for controlling the vibration of the vibrating member is provided. It is understood that the provision of the accommodating cavity facilitates the installation of the vibrating member and the battery, and the provision of the button 403 for controlling the vibration of the vibrating member on the end cap 402 prevents the user from accidentally touching the button 403 when holding the handle 40. The end cap 402 is detachably connected to facilitate the installation of the vibrating member and the replacement of the battery, and the end cap 402 is provided with anti-slip textures.
