The other end of the rotating member 120 is screwed to the driven member 130. The frame 52 has an opening 52a to expose the non-circular hole 120b. The user can insert a tool 60 (such as a hexagonal wrench) into the non-circular hole 120b as shown in FIG. 11 and rotate the tool 60 over 360 degrees to drive the rotating member 120 to rotate, so as to drive the lock tongue 140 to move from the unlocked position to the locked position . The hexagonal wrench is a tool that many users carry when riding a bicycle to adjust or repair the bicycle body. The bicycle lock 100 of this embodiment can be locked and unlocked by using this existing tool.

Fig. 12 is a perspective view of partial components of the bicycle lock of Fig. 3. Please refer to FIG. 12, the bicycle lock 100 of this embodiment includes at least one first elastic member 150 (two are shown). The first elastic member 150 is, for example, a compression spring and is connected between the base 110 and the bolt 140. When the user wants to unlock, the rotating member 120 can be rotated to drive the follower 130 to move from the position shown in FIGS. 7 and 8 in the reverse direction of the first direction D1 to the position shown in FIGS. 4 and 5. At this time, the lock tongue 140 is released by the follower 130 and is reset from the locked position shown in FIGS. 7 and 9 to the unlocked position shown in FIGS. 4 and 6 by the elastic force of the first elastic member 150 in the reverse direction of the second direction D2 position.

In this embodiment, the tongue 140 includes an extension portion 146 connected to the body portion 142, and two ends of the extension portion 146 protrude relative to the body portion 142. The two first elastic members 150 are respectively connected to two ends of the extension portion 146. In other embodiments, the lock tongue 140 may have other suitable shapes to be suitable for connecting the first elastic member 150, and the present invention is not limited thereto.

The bicycle lock 100 of this embodiment further includes a second elastic member 160 as shown in FIG. 5. The second elastic member 160 is, for example, a compression spring and is sleeved on the rotating member 120 and connected between the base 110 and the driven member 130. The follower 130 is adapted to be positioned on the base 110 by the elastic force of the second elastic element 160. When the rotating element 120 rotates, it needs to resist the elastic force of the second elastic element 160 to drive the follower 130 to move. With the configuration of the second elastic member 160, the follower 130 can be prevented from loosening due to insufficient engagement between the outer thread 120a of the rotating member 120 and the corresponding inner thread of the follower 130.

Fig. 13 is a cross-sectional view of part of the components of the bicycle lock of Fig. 3. In this embodiment, as shown in FIG. 13, the rotating member 120 includes a first shaft portion 122 and a second shaft portion 124 that are coaxial. The first shaft portion 122 is connected to the base 110 and the driven member 130, and the second shaft The portion 124 is rotatably connected to the first shaft portion 122 with a predetermined torque value. The second shaft portion 124 is adapted to receive an external force smaller than a predetermined torque value to drive the first shaft portion 124 to rotate. Thereby, when the rotating member 120 rotates to drive the driven member 130 to move to the limit position shown in FIG. 3 or FIG. 8, if the user continues to rotate the rotating member 120 and the torque is greater than the predetermined torque value, the second shaft portion 124 It will start to rotate relative to the first shaft portion 124 to avoid damage to the rotating member 120 and the driven member 130 due to excessive torque.

In summary, the bicycle lock of the present invention drives the bolt to lock by the rotation of the rotating member. The user only needs to turn the rotating member with a tool (such as a hexagonal wrench) to unlock or lock the bicycle lock. The lock does not need to carry the corresponding key, so as to improve the convenience of using the bicycle lock. In addition, since the rotating member is locked in a stepless manner, instead of being locked in a two-step manner like a general key, the user can rotate the rotating member to make the lock tongue firmly pressed against The functional components are locked to avoid excessive shaking of the functional components during riding.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
