[0043] A frame according to an embodiment of the present invention comprises the above-mentioned locking device c and a separable upper frame a and lower frame b. When it is necessary to lock the upper frame a and the lower frame b, the lower frame b is first controlled to rise, so that the lock head 6 on the rotating pin 5 on the lower frame b passes through the locking hole 2 on the upper frame a, and at this time, the top pin 8 is pressed down by the upper frame a, and the limit block 9 is pressed down synchronously, thereby releasing the lock of the rotating handle 7 on the lower frame b.

The first part is connected to the second cover plate 3 through a first gap between the lock head 6 and the lock seat 15, and the second part is connected to the partition plate 4 through a second gap between the bearing platform 16 and the turn handle 7. At the same time, the spherical match between the lock seat 15 and the bearing platform 16, that is, the spherical match between the first part and the second part, can make the first part float relative to the second part to adapt to the impact when the upper frame and the lower frame are locked, which has good practicality.

[0047] In the embodiment of the present invention, the bottom of the lock seat 15 adopts a spherical concave surface, and the top of the bearing platform 16 adopts a spherical convex surface. Of course, the two can also be arranged oppositely, and the embodiment of the present invention does not limit this.
