[0022] According to this specific embodiment, the drill bit 102 drills into the specified position, and then the staff pushes the connecting rod 104 to make the ring 105 squeeze the multiple beveled surfaces 114, thereby pushing the multiple extension blocks 107 to move, so that the multiple extension blocks 107 are respectively moved to the outside of the housing 103, thereby expanding the diameter of the end of the drill bit 102, thereby fixing it in the position after drilling, and then pouring cement concrete into the anchor rod 101 to seal and reinforce it. Therefore, the fixing method of the device is simple and fast, and the fixing work can be completed by pushing the connecting rod 104, which saves the working time of the staff and improves the working efficiency. After the ring 105 pushes out the multiple extension blocks 107, concrete is poured into the anchor rod 101, and then the mounting plate 109 is fixed by the multiple bolts 110. On the fixing ring 108, the right end of the anchor rod 101 is sealed. Through the setting of the thread 116, the drill bit 102 can drill into the designated position more easily and conveniently. Through the setting of the handle 111, it is more convenient for the staff to install the mounting plate 109, and it is convenient for the staff to take and use it. After the mounting plate 109 is fixed, the staff can pour concrete into the annular groove 112 to make the concrete seal and fix the multiple bolts 110 to prevent the multiple bolts 110 from loosening later. When the drill bit enters the designated position, the multiple extension blocks are prestressed with the cooperation of the anchor rod. After the tension is locked, grouting is used to fix it. The left end of the anchor rod is ductile, and its left side is a free end that can be slightly stretched. When the extension block is subjected to force, the free end extends and moves slightly.

[0023] Among them, each of the extension blocks 107 has a groove 113 at one end located in the shell 103, and each of the extension blocks 107 has a chamfered surface 114 at the right end. The shell 103 has multiple openings 115. The shell 103 is fixedly connected to the drill bit 102 and is located at the right end of the drill bit 102. The anchor rod 101 is connected to the shell 103 and is located at the right end of the shell 103. Multiple sliders 106 are respectively slidably adapted to the left inner wall of the shell 103. Multiple extension blocks 107 respectively pass through the corresponding openings 115 and are fixedly connected to the corresponding sliders 106. The connecting rod 104 is located inside the anchor rod 101, and the ring 105 is fixedly sleeved on the outside of the connecting rod 104, and the ring 105 is adapted to multiple chamfered surfaces 114. The drill bit 102 drills into the specified position, and then the staff pushes the connecting rod 104 to make the ring 105 squeeze the multiple beveled surfaces 114, thereby pushing the multiple extension blocks 107 to move, so that the multiple extension blocks 107 are respectively moved to the outside of the shell 103, thereby expanding the diameter of the end of the drill bit 102, and then the ring 105 is adapted to the multiple grooves 113 to limit and fix the multiple extension blocks 107, so that the drill bit 102 is partially fixed in the position after drilling, and then cement concrete is poured into the anchor rod 101 to seal and reinforce it. Therefore, the fixing method of the device is simple and quick, and the fixing work can be completed by only pushing the connecting rod 104, saving the working time of the staff and improving work efficiency.

[0024] Secondly, the fixing ring 108 is fixedly sleeved on the outside of the anchor rod 101, the mounting plate 109 is arranged at the right end of the anchor rod 101, and the plurality of bolts 110 respectively penetrate the fixing ring 108 and are respectively located in the mounting plate 109. After the circular ring 105 pushes out the plurality of extension blocks 107, concrete is poured into the anchor rod 101, and then the mounting plate 109 is fixed to the fixing ring 108 by the plurality of bolts 110, so as to seal the right end of the anchor rod 101.

[0025] Meanwhile, the drill bit 102 has a thread 116. The thread 116 enables the drill bit 102 to drill into a designated position more easily and conveniently.

[0026] In addition, the handle 111 is fixedly connected to the mounting plate 109 and is located at the right end of the mounting plate 109, and the annular groove 112 is fixedly connected to the left end of the fixing ring 108. The setting of the handle 111 makes it more convenient for the staff to install the mounting plate 109 and is convenient for the staff to take and use. After the mounting plate 109 is fixed, the staff can pour concrete into the annular groove 112 so that the concrete seals and fixes the multiple bolts 110 to prevent the multiple bolts 110 from loosening later.

[0027] When using the prestressed anchor rod 101 which is easy to fix for slope management of the utility model, the drill bit 102 is used to drill into the specified position, and then the staff pushes the connecting rod 104 to make the ring 105 squeeze the multiple beveled surfaces 114, and then push the multiple extension blocks 107 to move, so that the multiple extension blocks 107 are moved to the outside of the shell 103 respectively, thereby expanding the diameter of the end of the drill bit 102, so as to fix it in the position after drilling, and then pour cement concrete into the anchor rod 101 to seal and reinforce it. Therefore, the fixing method of the device is simple and fast, and the fixing work can be completed by only pushing the connecting rod 104, which saves the working time of the staff and improves the working efficiency. After the circular ring 105 pushes out the multiple extension blocks 107, concrete is poured into the anchor rod 101, and then the mounting plate 109 is fixed to the fixing ring 108 by the multiple bolts 110, so as to seal the right end of the anchor rod 101. Through the setting of the thread 116, the drill bit 102 can drill into the designated position more easily and conveniently. Through the setting of the handle 111, it is more convenient for the staff to install the mounting plate 109 and it is convenient for the staff to take and use it. After the mounting plate 109 is fixed, the staff can pour concrete into the annular groove 112 to make the concrete seal and fix the multiple bolts 110 to prevent the multiple bolts 110 from loosening later.
