One end is fixedly connected with a spring 802, and the other end of the spring 802 is fixedly connected to the inner wall of the slide groove 801; then the secondary keel 6 is aligned with the installation groove 5 and moved upward. Since the end of the clamping block 803 is a sloped structure, it has a guiding effect on the secondary keel 6. When the secondary keel 6 moves upward, the secondary keel 6 resists the clamping block 803 and slides in the direction away from the installation groove 5. The clamping block 803 drives the spring 802 to contract. When the limiting groove 7 on the secondary keel 6 is aligned with the clamping block 803, the spring 802 is reset, driving the clamping block 803 to slide and engage in the limiting groove 7, so that the secondary keel 6 is fixed.

Since the end of the clamping block 803 is in an inclined structure, it has a guiding effect on the secondary keel 6. When the secondary keel 6 moves upward, the secondary keel 6 resists the clamping block 803 and slides in a direction away from the installation slot 5. The clamping block 803 drives the spring 802 to contract. When the limiting groove 7 on the secondary keel 6 is aligned with the clamping block 803, the spring 802 is reset, driving the clamping block 803 slides and engages in the limiting groove 7, so that the secondary keel 6 is fixed. The operation is simple and flexible, and the installation efficiency of the secondary keel 6 is improved. When the secondary keel 6 needs to be removed, the screwdriver is inserted into the first groove 804 after passing through the second groove 805, and then the screwdriver is moved away from the limiting groove 7. The screwdriver drives the block 803 to slide until the block 803 is no longer engaged with the limiting groove 7, thereby releasing the fixation of the secondary keel 6, facilitating the quick removal of the secondary keel 6, and improving work efficiency.
