DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As attached Figure 1-4As shown, the utility model provides a connecting rod type hole-making drill rod, including an outer protective rod 1, and a hole-making drill rod protection device 2 is arranged inside the outer protective rod 1; the hole-making drill rod protection device 2 includes: a lifting component 21 and a cleaning component 22, and the cleaning component 22 is arranged at the lower end of the lifting component 21.

[0020] The lifting assembly 21 includes: a built-in groove 211, an assembly spring group 212, a lower mounting ring 213, an upper mounting ring 218, a docking slider 214, a docking slide groove 217, a lifting rod 216 and a pushing connecting rod 215. The built-in groove 211 is opened at the upper and lower ends of the outer protective rod 1, the upper end of the assembly spring group 212 is mounted on the lower end of the upper mounting ring 218, the lower end of the assembly spring group 212 is mounted on the upper end of the lower mounting ring 213, the outer wall of the lower mounting ring 213 is mounted on the inner wall of the lower end of the built-in groove 211, and the upper mounting ring 2 The inner wall 18 is installed on the outer wall of the upper end of the lifting rod 216, the docking slot 217 is opened on the outer wall of the lifting rod 216, the inner wall of the docking slot 217 is docked with the outer wall of the docking slider 214, the outer wall of the docking slider 214 is fixedly installed on the inner wall of the built-in groove 211, the lower end of the pushing connecting rod 215 is placed on the upper end of the lifting rod 216, and the lifting rod 216 is movably installed inside the built-in groove 211, the docking slot 217 and the docking slider 214 are adapted in size, and multiple groups of docking slots 217 and docking sliders 214 are provided.

[0021] The cleaning assembly 22 includes: a drill bit 223, a drilling block 224, a cleaning frame 221 and a scraper cleaning groove 222. The upper end of the drill bit 223 is installed at the lower end of the lifting rod 216. The cleaning frame 221 is opened at the upper and lower ends of the cleaning frame 221. The upper end of the cleaning frame 221 is fixedly installed on the outer wall of the lower end of the outer protective rod 1. The inner side of the drilling block 224 is installed on the side outer wall of the drill bit 223. The size of the drilling block 224 is adapted to the size of the scraper cleaning groove 222.

[0022] The specific implementation method is as follows: when using the utility model, the lifting rod 216 is pushed downward by pushing the connecting rod 215 to move downward. After the lifting rod 216 is moved downward, it drives the drill bit 223 installed at the lower end to move downward to drill holes. While the drill bit 223 is moving downward, the docking groove 217 provided at the upper end moves on the outer wall of the docking slider 214. When the lifting rod 216 moves downward, it drives the upper mounting ring 218 installed on the outer wall of the upper end to move downward. After the upper mounting ring 218 moves downward, it squeezes the assembly spring group 212 downward. After the assembly spring group 212 is squeezed and retracted, it can form a buffer for the up and down movement of the lifting rod 216. The moving effect can avoid the lifting rod 216 from having a violent collision during movement, which may reduce the service life of the lifting rod 216. After the use of the device, the lifting rod 216 moves up and retracts, driving the drill bit 223 to move up and retract. After the drill bit 223 moves up, the drilling block 224 installed on the outer wall can frequently scrape the material through the scraper cleaning groove 222 installed on the upper end, avoiding the problem of more soil and impurities sticking to the outer wall of the drill bit 223 and the drilling block 224, which makes it more difficult to clean the drilling block 224. The device can achieve self-cleaning by moving up and down, which greatly improves the practicality and ease of use of the entire device.

[0023] The working principle of the utility model is as follows: when the utility model is used, the lifting rod 216 is pushed downward by pushing the connecting rod 215 to move downward. After the lifting rod 216 completes the downward movement, it drives the drill bit 223 installed at the lower end to move downward to drill holes. While the drill bit 223 moves downward, the docking groove 217 arranged at the upper end moves on the outer wall of the docking slider 214. When the lifting rod 216 moves downward, it drives the upper mounting ring 218 installed on the upper outer wall to move downward. After the upper mounting ring 218 completes the downward movement, it squeezes the assembly spring group 212 downward. After the assembly spring group 212 is squeezed and retracted, it can form a buffering movement effect for the up and down movement of the lifting rod 216, so as to avoid the lifting rod 216 from violently hitting when moving, resulting in a reduction in the service life of the lifting rod 216. After the device is used, the lifting rod 216 moves upward and retracts, driving the drill bit 223 to move upward and retract. After the drill bit 223 moves upward, the drilling block 224 installed on the outer wall can often scrape the material through the scraper cleaning groove 222 installed at the upper end.
