When the extension length of the auxiliary keel 222 is adjusted, the triangular spring leaf 230 is continuously inserted into the blocking groove 228 and separated from the blocking groove 228 in the moving process of the auxiliary keel 222, so that the triangular spring leaf 230 is continuously deformed and vibrated, and a worker has certain operation hand feeling.

When the limiting plate 214 is inserted into the auxiliary keel 222, the limiting plate 214 firstly extrudes the arc-shaped surface of the arc-shaped clamping block 218, so that the arc-shaped clamping block 218 converts the direction of the force and presses down the clamping spring 217, the clamping spring 217 deforms, then the third clamping groove 220 and the second clamping groove 219 are aligned, the limiting plate 214 no longer blocks the limiting plate 214, and the clamping spring 217 releases elastic potential energy to extrude the arc-shaped clamping block 218 into the second clamping groove 219 and the third clamping groove 220.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
