More specifically, the driving hole 312 is a polygonal hole, and one end 322 of the second driving member 320 is a polygonal cylinder with an outer contour matching it. Therefore, when one end 322 of the second driving member 320 is inserted into the driving hole 312, it is in the XZ plane. An engaging effect will be produced, so that the second driving member 320 and the first driving member 310 can rotate in conjunction, but there is no engaging effect in the Y-axis direction, and they can move relatively.

Furthermore, as shown in the embodiment shown in FIGS. 4A to 4C, the housing 100 has a housing space 140 extending along the Y axis, and a side wall thread 144 is provided on the side wall of the housing space 140. The second driving member 320 is disposed in the accommodating space 140, and the second driving member 320 is a cylinder with a driving member thread 324 matching the side wall thread 144 on the side surface. By the abutment action between the side wall thread 144 and the driving member thread 324, when the first driving member 310 rotates, the second driving member 320 rotates in unison, so that the second driving member 320 faces the rear end 220 and one end 321 is along the Y axis Move in the direction to extend between different depths to the rear end 220. Wherein, the second driving member 320 has an inclined surface toward one end 321 of the rear end 220, which helps the end 321 move along the Y-axis direction to extend to different depths between the rear end 220 and expand the rear end 220. The lock 800 further includes an elastic member 500 such as a rubber ring for providing elastic force to make the rear end portions 220 approach each other.

As shown in the embodiment shown in FIG. 5A, the user can first rotate the force receiving portion 331 in one direction (please refer to FIG. 2A), so that the second driving member 320 moves in the Y-axis direction toward one end 321 of the rear end portion 220 to exit. Between the ends 220. At this time, due to the elastic force of the elastic member 500, the rear end portions 220 can be close to each other, so that the opening width of the front end portion 210 is reduced so as to be inserted into the lock hole 720. As shown in the embodiment shown in FIG. 5B, after the front end 210 is inserted into the lock hole 720, the user can rotate the force receiving portion 331 in the opposite direction, so that the second driving member 320 moves in the Y-axis direction toward one end 321 of the rear end 220. Part of it extends between the rear end 220. Thereby, the rear end portions 220 can be separated from each other, so that the opening width of the front end portion 210 is increased so as to be engaged with the lock hole 720. At this time, the user can further operate to lock the lock body 400 (see FIG. 2A) to fix the front end 210, so as to achieve the locking effect. As shown in another embodiment of FIG. 5C, after the front end 210 is inserted into the lock hole 710, the user can rotate the force receiving portion 331 in the opposite direction, so that the second driving member 320 faces the rear end 220 and one end 321 is along the Y axis direction. Move to extend between the rear end portions 220 to a greater extent. At this time, the rear end portions 220 can be farther away from each other, so that the opening width of the front end portion 210 is further increased so as to be engaged with the larger lock hole 710. Then, the user can further manipulate the lock body 400 to achieve the locking effect.

Viewed from different angles, the lock 800 of the present invention utilizes the rotating drive device 300 to achieve the purpose of adjusting the opening width of the rotating hook 200. Among them, since the force applying member 330, the first driving member 310, and the second driving member 320 of the driving device 300 are matched and engaged with each other using structures such as gears and threads, the opening of the rotary hook 200 can be controlled according to the degree of rotation. The opening width, and the rotation is essentially a continuous and non-segmented operation, so the opening width of the continuous and non-segmented control rotating hook 200 can also be achieved. It can be used for different sizes of lock holes and has better Ease of use.
