The rear end of the front fixing column 218 is installed at the front end of the telescopic rod body 217, the rear end of the telescopic rod body 217 is installed at the front end of the rear fixing column 216, a limit protection block 215 is installed at the rear end of the rear fixing column 216, one end of the upper side support frame 213 is installed on the outer wall of the side of the front fixing column 218, one end of the lower side support frame 2102 is installed on the other outer wall of the front fixing column 218, a second assembly spring long rod 2104 is installed at the lower end of the second sliding block 2103, the front end of the front fixing column 218 is installed at one end of the shaft rod body 219, the second sliding block 2103 and the first sliding block 214 are movably installed in the moving groove 211, the other ends of the assembly spring rod 212 and the second assembly spring long rod 2104 are respectively fixedly installed at both ends of the upper end of the moving groove 211, the other end of the lower side support frame 2102 is rotatably installed with the second sliding block 2103, the other end of the upper side support frame 213 is installed with the first sliding block 214, and the assembly spring rod 212 is installed at the upper end of the first sliding block 214.

[0020] The terminal shock absorption protection assembly 22 includes: a shock absorption spring sleeve 221, a pressing rod 222, a transverse frame plate 224, a moving hole 223, and a diversion groove 225. The moving hole 223 is opened at the upper and lower ends of the transverse frame plate 224. The lower end of the pressing rod 222 penetrates through the upper and lower ends of the moving hole 223. The lower end of the shock absorption spring sleeve 221 is installed at the upper end of the moving hole 223. The upper end of the shock absorption spring sleeve 221 is installed at the lower end of the shaft rod body 219. Two groups are provided for the shock absorption spring sleeve 221, the pressing rod 222, the moving hole 223, and the diversion groove 225. The two ends of the transverse frame plate 224 are installed on the inner sides of the two side support rods 1.

The upper ends of the two shock absorption spring sleeves 221 are installed at the lower ends of the two shaft rod bodies 219.

[0021] The specific implementation method is as follows: When the upper and lower ends of the shaft rod body 219 are impacted during the use of the present utility model, the lower end of the shaft rod body 219 can perform telescopic extrusion through the installed shock absorption spring sleeve 221 for shock absorption work. When the shock absorption spring sleeve 221 expands and contracts, the lower end of the pressing rod 222 installed at the lower end penetrates through the moving hole 223 and moves downward inside the moving hole 223. After the impact ends, it can rebound to its original position and wait for the next shock absorption protection work. When the two ends of the shaft rod body 219 are impacted, the two side shock absorption assemblies 21 can be used for protection work. When the side shock absorption assemblies 21 are in use, they can perform telescopic shock absorption work through the two first damping spring sleeves 210. When the first damping spring sleeves 210 perform shock absorption work, the two lower side support frames 2102 and the upper side support frame 213 installed on the side move outward to shorten the distance between the two side shock absorption assemblies 21 for shock absorption protection work. The two ends of the transverse frame plate 224 can be movably installed on the inner sides of the two side support rods 1. After the distance between the two side shock absorption assemblies 21 is reduced, the transverse frame plate 224 can penetrate through the front and rear sides of the side support rods 1 to assist the two side shock absorption assemblies 21 in performing shock absorption work. By adopting side shock absorption and lower-end shock absorption work, the device avoids the problem of breakage and damage of the shaft rod body 219 caused by collision and impact during the use of the shaft rod body 219. The shaft rod body 219 is protected synchronously by the two side shock absorption assemblies 21 and the terminal shock absorption protection assembly 22, further enhancing its service life and use stability.

[0022] Working principle of the utility model: When the upper and lower ends of the shaft rod body 219 are impacted during the use of the utility model, the lower end of the shaft rod body 219 can perform shock absorption work through the telescopic extrusion of the installed shock absorption spring sleeve 221. When the shock absorption spring sleeve 221 expands and contracts, the lower end of the extrusion rod 222 installed at the lower end penetrates through the moving hole 223 and moves downward inside the moving hole 223. After the impact ends, it can rebound to its original position and wait for the next shock absorption protection work. When the two ends of the shaft rod body 219 are impacted, the two sets of side shock absorption components 21 can be used for protection work. When the side shock absorption components 21 are in use, they can perform telescopic shock absorption work through the two sets of first damping spring sleeves 210. When the first damping spring sleeves 210 perform shock absorption work, the two sets of lower side support frames 2102 and upper side support frames 213 installed on the sides move outward to shorten the distance between the two sets of side shock absorption components 21 for shock absorption protection work. Both ends of the cross frame plate 224 can be movably installed inside the two sets of side support rods 1. After the distance between the two sets of side shock absorption components 21 is reduced, the cross frame plate 224 can penetrate through the front and rear sides of the side support rods 1 to assist the two sets of side shock absorption components 21 in performing shock absorption work. The device adopts side shock absorption and lower end shock absorption work.
