When the first gear 403 is driven to rotate, the first gear 403 extrudes the inclined surface of the triangular block 408, so that the first spring 411 is stretched, so that the triangular block 408 is away from one side of the first gear 403, so that the triangular block 408 can avoid affecting the rotation of the first gear 403. When the connecting device 5 is used, the blade 502 is manually slid into the fixed groove 501, the sliding block 508 is manually controlled to slide towards the connecting block 3, and then the sliding block 508 is arranged on the inner wall of the sliding groove 507 close to one side of the connecting block 3. The fourth spring 511 pulls the clamping strip 512 towards the inside of the groove 509, so that the clamping strip 512 is arranged in the groove 509. The clamping strip 512 is slid to the bottom of the inner wall of the groove 509, and then the clamping strip 512 is limited in the groove 509 by the rubber block 513, and then the end of the clamping strip 512 away from the groove 509 is arranged on one side of the inner wall of the sliding groove 507 away from the connecting block 3. In this way, the fixed rod 503 can be inserted into the connecting block 3, and then the fixed rod 503 is inserted through one side of the connecting block 3 and then through the blade 502. The third spring 506 pulls the connecting frame 504 towards the connecting block 3, so that the fixed rod 503 can be well limited in the blade 502. Reverse operation can replace the blade 502, so that the blade 502 can be replaced when it is damaged.
[0031] It should be noted that all the damping rods in the case are telescopic dampers, which can absorb energy during telescoping.
