In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 5, an embodiment of the present invention discloses a fast locking mechanism 100, the fast locking mechanism 100 is used for fast assembling a second plate on a first plate, the first plate is used as a main plate 200, and the second plate is an auxiliary plate 300 assembled on the main plate 200.

The quick-locking mechanism 100 includes: a base 10, a rotation member 20, a spring 30 and a screw 40.

The main plate body is provided with a mounting hole in advance, a notch (not shown in the drawing) is formed in one side of the mounting hole, an outer step 13 is formed on the periphery of the seat body 10, the seat body 10 is arranged at the mounting hole, the outer step 13 is limited outside the mounting hole, a convex strip 14 is arranged at the outer step 13, the convex strip 14 penetrates through the notch, and welding can be carried out at the convex strip 14 and the notch to fix the seat body 10 on the main plate body 200.

As shown in fig. 3, the seat body 10 has an inner hole passing through in the axial direction, a main end surface 11 and a stepped surface 12 sinking to a certain height are formed on an end surface of a first end of the seat body 10, and the stepped surface 12 is located at a side where the sub-plate 300 needs to be installed.

The rotation-clamping member 20 includes a rotating shaft 22 and a clamping head 21 formed at a first end of the rotating shaft 22 (the first end of the rotating shaft 22 is located on the same side as the first end of the housing 10); the shaft 22 extends into the inner hole of the housing 10 and can rotate in the inner hole to enable the chuck 21 to rotate relative to the housing 10.

The spring 30 is disposed in the seat 10 and sleeved on the rotating shaft 22, a stopping step 15 facing the second end is formed in the seat 10, a screw 40 is disposed at an end of the rotating shaft 22, the spring 30 is disposed between the stopping step 15 and a nut of the screw 40, and the spring 30 is in a compressed state so that the spring 30 can apply an elastic force to the rotation-locking member 20 facing the second end.

The rotation clamping part 20 is provided with two radial extending parts 211, and an included angle is formed between the two radial extending parts 211, and the included angle satisfies the following conditions: when one of the radial extensions 211 is rotated to a position opposite to the stepped surface 12, the other radial extension 211 abuts against the main end surface 11.

When the sub-plate 300 needs to be installed on the main plate 200, the side of the sub-plate 300 abuts against the stepped surface 12, and then the rotation-locking member 20 is rotated to rotate one of the radial extending portions 211 to a position opposite to the stepped surface 12, so that the radial extending portion 211 and the stepped surface 12 form a clamping space, and the side of the sub-plate 300 is located in the clamping space, and under the elastic force of the spring 30, the radial extending portion 211 clamps the sub-plate 300.
