[0023] Example

[0024] See also Figure 1-Figure 4 The utility model provides a drill bit that is easy to disassemble, including a connecting seat 100 and a disassembly assembly 200.

[0025] Among them, the disassembly component 200 is installed in the mounting seat 110 on the connecting seat 100. Through the disassembly component 200, the connecting column 130 on the drill body 140 can be removed from the mounting seat 110, reducing the possibility of inconvenience in disassembling and replacing the cutter head when the cutter head is damaged.

[0026] See also Figure 1-Figure 3 The upper surface of the connecting seat 100 is connected to the mounting seat 110, and a mounting hole 120 is opened on the top of the mounting seat 110. A connecting column 130 is inserted into the mounting hole 120, and a drill body 140 is connected to the top of the connecting column 130. In the specific implementation, the connecting column 130 at the lower end of the drill body 140 is inserted into the mounting hole 120 of the mounting seat 110, which is conducive to installing the drill body 140 on the mounting seat 110 of the connecting seat 100.

[0027] In this embodiment, a shielding sleeve 160 is threadedly sleeved on the surface of the connecting seat 100, and the shielding sleeve 160 is sleeved on the surface of the mounting seat 110. In a specific implementation, the shielding sleeve 160 is rotated to move upward, and the shielding sleeve 160 will shield the pulling member 220, which is beneficial to improve the stability of the pulling member 220 in the notch 170; an elastic ring 161 is connected to the inside of the shielding sleeve 160, and the elastic ring 161 fits with the surface of the mounting seat 110. In a specific implementation, the elastic ring 161 is provided in the shielding sleeve 160 to make the elastic ring 161 fit with the surface of the mounting seat 110, thereby reducing the contact between the shielding sleeve 160 and the mounting seat 110, and the possibility of wear. It should be noted that the elastic ring 161 can be made of rubber or silicone.

[0028] A protective ring 121 is connected to the mounting hole 120, and the protective ring 121 is sleeved on the surface of the connecting column 130. In a specific implementation, a protective ring 121 is provided in the mounting hole 120, and the connecting column 130 at the lower end of the drill body 140 is inserted into the mounting hole 120 so that the connecting column 130 fits with the inner wall of the protective ring 121, which can reduce the gap between the connecting column 130 and the mounting hole 120, and is conducive to improving the stability of the connecting column 130 in the mounting hole 120. It should be noted that the protective ring 121 can be made of rubber or silicone.

[0029] See also Figure 1-Figure 4 Two disassembly assemblies 200 are arranged in the connection seat 100, and the disassembly assembly 200 includes a sliding member 210 and a pulling member 220. The sliding member 210 and the pulling member 220 are both slidably arranged in the connection seat 100, and the sliding member 210 is fixedly connected to the pulling member 220. One end of the pulling member 220 is connected to a plug rod 230. The surface of the connecting column 130 is provided with a plug hole 150 corresponding to the plug rod 230. The mounting seat 110 is connected with a spring 240, and the spring 240 is sleeved on the surface of the sliding member 210. In the specific implementation, by pulling the pulling member 220, the sliding member 210 can be driven to move. The connecting column 130 is no longer restricted, and the staff can take the connecting column 130 out of the mounting hole 120, which is convenient for removing the drill body 140 from the mounting seat 110, thereby reducing the possibility of inconvenience in removing the cutter head for replacement when the cutter head of the drill body 140 is damaged. The sliding member 210 can be reset by the elastic force of the spring 240, so that the insert rod 230 is inserted into the socket 150 of the connecting column 130, which can restrict the connecting column 130 and facilitate the stability of the connecting column 130 in the mounting seat 110.

[0030] In this embodiment, the sliding member 210 includes a sliding rod 211 and a limit block 212. The sliding rod 211 is slidably arranged in the mounting seat 110, and the sliding rod 211 is fixedly connected to the limit block 212 and the pulling member 220 respectively. The spring 240 is sleeved on the surface of the sliding rod 211, and one end of the spring 240 is connected to the limit block 212; a placement cavity 111 is opened in the mounting seat 110, and the other end of the spring 240 is connected to the inner wall of the placement cavity 111, and the limit block 212 is in contact with the inner wall of the placement cavity 111. In the specific implementation, the spring 240 is placed in the placement cavity 111, which is beneficial to protecting the spring 240. When the staff drives the pulling member 220 to move, the limit block 212 can move along the inner wall of the placement cavity 111, reducing the possibility that the sliding rod 211 and the limit block 212 will fall off from the placement cavity 111

[0031] A notch 170 is provided on the surface of the connecting seat 100, and the pulling member 220 is in contact with the inner wall of the notch 170. In a specific implementation, the pulling member 220 is arranged in the notch 170 on the surface of the connecting seat 100, which is conducive to the compactness of the components of the device; the pulling member 220 includes a connecting block 221 and a pulling block 222, and the connecting block 221 is fixedly connected to the sliding rod 211 and the pulling block 222 respectively, and the connecting block 221 and the pulling block 222 are in contact with the inner wall of the notch 170, and a groove is provided on the upper surface of the pulling block 222.

[0032] Specifically, the working principle of the drill bit that is easy to disassemble is as follows: when in use, by rotating the shielding sleeve 160 on the connecting seat 100, the shielding sleeve 160 can be moved downward, and the connecting block 221 is no longer restricted. By pulling the pull block 222, the connecting block 221 and the sliding rod 211 can be driven to move, so that the limit block 212 moves along the inner wall of the placement cavity 111, which is beneficial to the stability of the limit block 212 during the movement process, and the limit block 212 will drive the insertion rod 230 to move, and the insertion rod 230 will move from the surface of the connecting column 130. The rod 230 is pulled out from the socket 150 on the surface, so that the rod 230 no longer restricts the connecting column 130, which makes it convenient for the staff to remove the drill body 140 from the mounting seat 110, and reduces the possibility of inconvenience in removing the cutter head for replacement when the cutter head of the drill body 140 is damaged. The connecting column 130 is inserted into the mounting hole 120, and the elastic force of the spring 240 resets the limit block 212, and the rod 230 is inserted into the socket 150 of the connecting column 130, which is beneficial to the stability of the connecting column 130 in the mounting hole 120.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
