[0026] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] A rotary drilling tooth head quick-release tool, as shown in Figure 1 And Figure 2 As shown, it comprises an operating rod 1, a clamping mechanism arranged at one end of the operating rod 1, and a driving mechanism arranged at the other end of the operating rod 1, the clamping mechanism comprises a connecting frame 2 and a clamping piece 4 arranged on the connecting frame 2, the clamping piece 4 is provided with a clamping groove 5 capable of cooperating with the rotary drilling tooth head, the driving mechanism comprises a positioning block 8 and a sliding block 9, the positioning block 8 is arranged on the operating rod 1, the sliding block 9 is arranged between the connecting frame 2 and the positioning block 8, the sliding block 9 is slidingly installed on the operating rod 1, and the sliding direction of the sliding block 9 is the same as the length direction of the operating rod 1.

[0028] The positioning block 8 is an annular structure, and is fixed on the operating rod 1. The sliding block 9 is provided with an assembly hole matched with the operating rod 1. In actual use, the operator can use the clamping groove 5 on the clamping piece 4 to match with the rotary drilling tooth head, realize the clamping connection between the clamping piece 4 and the rotary drilling tooth head, and then repeatedly slide the sliding block 9 along the operating rod 1, use the impact force of the sliding block 9 and the positioning block 8 to loosen the rotary drilling tooth head, and then realize the convenient disassembly of the rotary drilling tooth head, which is beneficial to reduce the disassembly and assembly difficulty of the rotary drilling tooth head and improve the construction efficiency.

[0029] Preferably, the connecting frame 2 is uniformly provided with at least three connecting rods 3. Each connecting rod 3 is connected to one end of the connecting frame 2 and the other end of the clamping piece 4. The clamping piece 4 is a U-shaped structure, and three connecting rods 3 are arranged at the middle and both ends of the clamping piece 4. One end of each connecting rod 3 is fixed on the connecting frame 2, and the other end is fixed on the clamping piece 4. By using the U-shaped clamping piece 4 and arranging three connecting rods 3 to connect different positions of the clamping piece 4, the structural strength of the clamping piece 4 itself and the connecting position of the clamping piece 4 and the connecting frame 2 can be improved, and the reliability of the tool in use is improved. At the same time, by using the above structure, the weight of the tool can be reduced under the premise of ensuring the overall structural strength of the tool, and the operator can use the tool conveniently.

[0030] In addition, the skilled person in the art can also select other structures of the clamping piece 4 according to actual needs, and arrange multiple connecting rods 3 according to actual needs to realize the stable connection between the clamping piece 4 and the connecting frame 2.

[0031] Preferably, the connecting frame 2 and the operating rod 1 are detachably connected. The operating rod 1 is provided with a plug-in part 11, the connecting frame 2 is provided with a plug-in groove 12 matched with the plug-in part 11, the connecting frame 2 is provided with a detachable positioning pin 10 at a position corresponding to the plug-in groove 12, and the plug-in part 11 is provided with a pin hole matched with the positioning pin 10. The connecting frame 2 is provided with an assembly hole for mounting the positioning pin 10, and the assembly hole is communicated with the plug-in groove 12.

[0032] In actual application, the positioning pin 10 is arranged at least two intervals. The positioning pin 10 can be arranged at two intervals along the length direction of the operating rod 1, which is beneficial to improve the stability of the connection between the operating rod 1 and the connecting frame 2. By using the detachable mode, the installation of the sliding block 9 is facilitated, and the use and maintenance difficulty of the tool is reduced. Moreover, it is convenient for the operator to replace the connecting piece with a suitable clamping piece 4 according to actual needs, which is beneficial to improve the convenience of using the tool.

[0033] Preferably, the operating lever 1 is provided with a threaded sleeve 6, and both the operating lever 1 and the connecting frame 2 are provided with external threads that mate with the threaded sleeve 6. The threaded sleeve 6 can further strengthen the connection between the operating lever 1 and the connecting frame 2, improving the stability of their connection. At the same time, the threaded sleeve 6 can also provide a good limiting effect on the positioning pin 10, preventing the positioning pin 10 from falling out.

[0034] In practical applications, the connecting frame 2 is equipped with a limiting ring 7 that mates with the threaded sleeve 6. For example, the limiting ring 7 is fixed to the connecting frame 2. The limiting ring 7 not only effectively limits the movement of the threaded sleeve 6, preventing excessive movement and ensuring a stable connection between the connecting frame 2 and the operating rod 1 after the threaded sleeve 6 is screwed into place, but also protects the positioning pin 10, preventing it from dislodging. Furthermore, the limiting ring 7 can also mate with the threaded sleeve 6, distributing the force on the threaded sleeve 6 by pressing against its top surface, thus preventing deformation and damage.

[0035] Preferably, both the slider 9 and the threaded sleeve 6 have anti-slip textures on their outer sides. These anti-slip textures facilitate the operator's sliding of the slider 9 and tightening of the threaded sleeve 6.

[0036] Specifically, when using this quick-release tool, the locking groove 5 on the clamping fastener 4 can be used to engage with the rotary drilling tooth, allowing the clamping fastener 4 to be inserted into the mounting groove of the rotary drilling tooth. Then, the operator can slide the slider 9 downwards. The force of the collision between the slider 9 and the positioning block 8 applies a downward pulling force to the rotary drilling tooth to be removed. By repeatedly moving the slider 9, the rotary drilling tooth can be loosened and finally removed.

[0037] The rotary drilling tooth quick-release tool described in this utility model has the advantages of simple structure, low cost, convenient use and maintenance, and easy operation. It can be used to disassemble rotary drilling teeth, and the disassembly process is simple and easy to operate, which can save the operator's labor time, reduce their labor intensity, reduce manual input, and improve construction efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
