The rotating shaft 44 passes through and is fixedly connected to the front surface of the connecting rod 42. When the rotating shaft 44 rotates, the connecting rod 42 will swing.

[0034] Reference Figure 1 , Figure 4 , Figure 5 The slide groove 401 is opened in a circular ring shape, the slider 41 is slidably connected to the inner wall of the slide groove 401, and the protrusion at the top of the slider 41 is slidably connected in the slide groove 401. When the outer tube 1 is hit, the outer tube 1 can rotate to disperse the impact force. The connecting block 46 penetrates and is slidably connected to the lower surface of the slider 41, sliding longitudinally. One end of the connecting spring 45 is fixedly connected to the upper surface of the connecting block 46, and the other end of the connecting spring 45 is fixedly connected to the inner wall at the top of the slider 41. When the outer tube 1 is hit, the slider 41 will approach the inner wall at the top of the connecting block 46, and will squeeze the connecting spring 45 to generate a reaction force. The reaction force of the connecting spring 45 can play a buffering role.

[0035] Reference Figure 1 , Figure 4 , Figure 5 One end of the torsion spring 43 is fixedly connected to the inner wall on the right side of the slider 41, and the other end of the torsion spring 43 is fixedly connected to the upper surface of the rotating shaft 44. When the rotating shaft 44 rotates, it will squeeze the torsion spring 43 to generate a reaction force. The rotating shaft 44 is rotatably connected to the inner wall on the front side of the slider 41.

[0036] Reference Figure 1 , Figure 4 , Figure 5There are multiple groups of sliders 41, connecting rods 42, torsion springs 43, rotating shafts 44, connecting springs 45, and connecting blocks 46. The multiple groups of sliders 41, connecting rods 42, torsion springs 43, rotating shafts 44, connecting springs 45, and connecting blocks 46 are arranged in a circular array with the center of the inner tube 3 as the origin. The sliders 41 and connecting rods 42 are connected in pairs to form a ring. When impacted, they will deform to disperse the impact force and play a buffering role.

[0037] Reference Figure 1-Figure 3 The right surface of the convex flange 21 is fixedly connected to the left surface of the outer tube 1, the convex flange 21 is rotatably connected to the left end of the outer wall of the inner tube 3, the concave flange 22 is rotatably connected to the right end of the outer wall of the inner tube 3, the convex flange 21 and the concave flange 22 can rotate, the clamping block 23 is inserted into the inner wall of the clamping groove 201, the positioning block 25 is inserted into the inner wall of the positioning groove 202, and the clamping block 23 and the clamping groove 201 are provided in two groups, which are distributed left and right with the center line of the inner tube 3.

[0038] Reference Figure 1-Figure 3 The positioning block 25 is slidably connected to the inner wall of the convex flange 21 and slides longitudinally. One end of the compression spring 24 is fixedly connected to the upper surface of the positioning block 25, and the other end of the compression spring 24 is fixedly connected to the inner wall at the top of the convex flange 21. When the positioning block 25 moves upward, it will squeeze the compression spring 24 to generate a reaction force. The lower surface of the positioning block 25 is opened in an arc shape. When the arc on the lower surface of the positioning block 25 is squeezed, the positioning block 25 will move upward.

[0039] Working principle: when multiple outer tubes 1 need to be installed together, insert the convex flange 21 into the concave flange 22, and insert the clamping block 23 into the clamping slot 201. At this time, the arc surface of the positioning block 25 will be squeezed by the clamping block 23, and the positioning block 25 will move upward to squeeze the compression spring 24 to generate a reaction force. When the clamping block 23 and the clamping slot 201 are plugged in, the reaction force of the compression spring 24 will push the positioning block 25 to move down and plug into the positioning slot 202, and the convex flange 21 and the concave flange 22 will be initially fixed. At this time, the threaded holes on the concave flange 22 and the convex flange 21 will be aligned, and the bolts are tightened to complete the fixation.

[0040] When the outer tube 1 is subjected to external impact, the outer tube 1 will rotate to disperse the impact force, and the slider 41 will slide along the slide groove 401. When the outer tube 1 is impacted, it will drive multiple connecting rods 42 to swing and drive the rotating shaft 44 to rotate. The swinging connecting rod 42 will disperse the force and play a role of force distribution. The rotating rotating shaft 44 will squeeze the torsion spring 43 to generate a reaction force, and the connecting block 46 will retract into the slider 41 to squeeze the connecting spring 45 to generate a reaction force. Under the action of the force distribution and the reaction force of the torsion spring 43 and the connecting spring 45, most of the impact force can be buffered, greatly reducing the impact force transmitted to the inner tube 3, and effectively protecting the inner tube 3. After the impact force is released, the reaction force of the torsion spring 43 and the connecting spring 45 will drive the device to reset.
