Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1, as shown in Figure 1-4:

A shock absorbing structure suitable for branch cutting machinery, comprising shock absorbing rods and sleeves 6, lock sections 1 are provided at the upper and lower ends of the shock absorbing rod, and the shock absorbing rod is composed of three parts, which are an upper rod body 2, The damping spring 9 and the lower rod body 8, the upper rod body 2 is inserted into the top end of the sleeve 6, the lower rod body 8 is inserted into the bottom end of the sleeve 6, the damping spring 9 is located inside the sleeve 6, and is respectively connected with the upper rod body 2 and the lower rod body 8. Fixed connection, the upper rod body 2 and the lower rod body 8 are respectively provided with connecting raised pipes 3 on both sides, and a detachable connecting rod 7 is arranged between the upper and lower corresponding two connecting raised pipes 3, and the connecting rod 7 passes through the threaded rod 4 Connected with the connecting protruding pipe 3 , a moving block 5 is arranged on the inner side of the connecting rod 7 , and the moving block 5 is vertically slidably connected with the outer wall of the sleeve 6 . In order to facilitate shock absorption and protect the shock absorbing spring 9, the sleeve 6 is provided with an insertion slot 601, the shock absorbing spring 9 is located inside the insertion slot 601, the upper rod body 2 and the lower rod body 8 are respectively inserted into the insertion slot 601, and the lower The top end of the rod body 8 is provided with an extended thin rod, and the bottom end of the insertion slot 601 is provided with a through port 602 corresponding to the extended thin rod. In order to facilitate sliding, reduce the use of lubricating oil and save resources, one side of the moving block 5 is provided with an I-shaped slider 501, and the sleeve 6 is provided with a chute 603 for use with the I-shaped slider 501, and there is a gap between the two.
