[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] The lock of this embodiment, such as Figures 1 to 5 As shown, the lock comprises a lock housing 1, a locking mechanism 5, and a transmission member 2. The locking mechanism 5 is mounted on the lock housing 1. The transmission member 2 is slidably mounted on the lock housing 1 and is constrained by the locking mechanism 5. The transmission member 2 can only be operated to move after the locking mechanism 5 inputs the correct command. The locking mechanism 5 can adopt the existing technology of the combination wheel mechanism, key lock cylinder mechanism, etc., and will not be elaborated here. The main improvements are:

[0034] The top of the lock case 1 is also provided with two outwardly open lock holes 01. A retaining seat 3 is mounted within the lock case 1. The retaining seat 3 is provided with two retaining grooves 31 aligned one-to-one with the lock holes 01. Each retaining groove 31 has two integrally formed elastic arms 32 on the opposite side walls. The inner side of the elastic arms 32 is provided with retaining protrusions 33 extending toward the retaining grooves 31, which are used to secure an object inserted through the lock hole 01. The elastic arms 32 are forced to swing away from the retaining grooves 31 to release the object. Extending grooves 02 are provided on the sides of the lock hole 01, extending through the side of the lock case 1, to facilitate the insertion of the locked object.

[0035] A stop seat 4 is also provided at the clamping seat 3. In the locked state, the stop seat 4 presses against the outer side of the elastic arm 32 to limit its swing; in the unlocked state, the transmission member 2 drives the stop seat 4 to move to release the restriction on the elastic arm 32.

[0036] In this embodiment, the stop seat 4 is movably mounted at the bottom of the retaining seat 3. In the locked state, the transmission member 2 abuts the stop seat 4 in the upper position; in the unlocked state, the transmission member 2 drives the stop seat 4 to the lower position. The transmission member 2 and the stop seat 4 are perpendicular to each other in their directions of movement. A limiting protrusion 21 is provided on the top of the transmission member 2, and a clearance groove 41 is provided at the bottom of the stop seat 4. In the unlocked state, the transmission member 2 moves, causing the limiting protrusion 21 to sink into the clearance groove 41, thereby lowering the stop seat 4. A spring is installed within the lock housing 1 to apply force to the stop seat 4. One end of the spring abuts the retaining seat 3, while the other end abuts the stop seat 4, thereby maintaining the downward unlocking tendency of the stop seat 4, and automatically descending after unlocking. Along the sliding direction of the transmission member 2, a matching inclined surface 22 is provided between the wall of the clearance groove 41 and the limiting protrusion 21. This surface can actually be replaced with a matching curved surface to facilitate perpendicular movement from the unlocked position to the locked position.

[0037] In this embodiment, the stop base 4 comprises an integrated stop base 42 and a stop stand 43. The retaining base 3 is provided with a clearance hole 34 adjacent to the elastic arm 32, and the stop stand 43 is inserted into the clearance hole 34. Two retaining slots 31 are arranged side by side, with the elastic arm 32 positioned on opposite sides of each retaining slot 31. There are three stop stands 43, with the center stop stand 43 simultaneously restraining one of the elastic arms 32 in both retaining slots 31. Both the clearance hole 34 and the stop stand 43 are arc-shaped.

[0038] During use, the transmission member 2 moves to the unlocked position, the limiting protrusion 21 sinks into the clearance groove 41, the stop seat 4 is in a low position, and the stopper 43 does not contact the opposite side of the retaining protrusion 33 of the elastic arm 32. This allows the retaining protrusion 33 to deform outward, allowing an external object to be inserted through the lock hole 01 until it is securely engaged by the retaining protrusion 33. At this point, because the elastic arm 32 is not completely blocked by the stopping protrusion 43, the retaining protrusion 33 is squeezed and deformed. Therefore, external forces can still overcome the force of the retaining protrusion 33 and remove the locked object. To lock, the transmission member 2 moves to the locked position, the limiting protrusion 21 is offset from the clearance groove 41, the stop seat 4 is in a high position, and the stopping protrusion 43 contacts the elastic arm 32. This prevents the elastic arm 32 from deforming outward, and the retaining protrusion 33 faces inward to secure the locked object.
