[0027] The effect achieved by the entire Embodiment 1 is that by pressing the two first limit blocks 11, the two first limit blocks 11 drive the two sliders 9 to contract into the two placement grooves 8 respectively. At the same time, the first return spring 10 starts to contract under the extrusion of the two sliders 9. Subsequently, the mounting post 4 is inserted into the fixed seat 3 and moved downward. When the positions of the two first limit blocks 11 and the two limit grooves 7 correspond, under the elastic force of the first return spring 10, the two first limit blocks 11 are driven to pop out from the two limit grooves 7 respectively, thereby limiting and fixing the mounting post 4, making it convenient to install the reamer head 5. At the same time, it is also convenient to disassemble and replace different types of reamer heads 5 for processing and use.

[0028] Embodiment 2: As Figure 1 - Figure 5 shown, the shock absorption mechanism 2 includes a damper 201. The damper 201 is installed in the mounting seat 1. The top of the damper 201 is fixedly connected to a support plate 202. The top of the support plate 202 is fixedly connected to the fixed seat 3. A rectangular groove 203 is opened in the mounting seat 1. A fixed rod 204 is fixedly connected in the rectangular groove 203. A moving plate 205 is sleeved on the outer surface of the fixed rod 204. One side of the moving plate 205 and the bottom of the support plate 202 are both fixedly connected with U-shaped blocks 206. A connecting rod 207 is rotatably connected inside the U-shaped blocks 206. A second return spring 208 is fixedly connected to the inner side of the mounting seat 1. The limiting mechanism 6 includes a fixing plate 601. The fixing plate 601 is fixedly connected to the outer top of the fixed seat 3. The top of the fixing plate 601 is fixedly connected to a fixed shell 602. A screw rod 603 is rotatably connected inside the fixed shell 602. A rotary cap 604 is installed at one end of the screw rod 603. The other end of the screw rod 603 is movably connected to a movable sleeve 605. A second limit block 606 is arranged at one end of the movable sleeve 605. A positioning block 12 is fixedly connected to the inner surface of the fixed seat 3. A positioning groove 13 is opened on the outer surface of the mounting post 4. The outer bottom of the mounting seat 1 is fixedly connected to a mounting disc 14. Mounting holes 15 are opened on the surface of the mounting disc 14.

[0029] The effect achieved by the entire Embodiment 2 is that through the provided shock absorption mechanism 2, when the reamer head 5 is in the machining process, the machine will generate a certain vibration. When the support plate 202 is subjected to the vibration, it will squeeze the damper 201. At the same time, under the action of the U-shaped block 206 and the connecting rod 207, the moving plate 205 is driven to move, and the second return spring 208 starts to contract due to the movement of the moving plate 205. Under the elastic force of the second return spring 208 and the damping effect of the damper 201, it plays a role in buffering and shock absorption, enabling the reamer head 5 to maintain a certain stability and improving the machining quality. Then, through the provided limiting mechanism 6, by rotating the two rotating caps 604, the two screw rods 603 respectively drive the two second limiting blocks 606 to move relatively through the two movable sleeves 605, so that the two second limiting blocks 606 move to the upper end of the mounting column 4, and the upper end of the mounting column 4 is limited by the two second limiting blocks 606, preventing the mounting column 4 from detaching from the fixed seat 3 during the rotational machining of the reamer head 5, and further improving the stability of the installation connection. When the mounting column 4 is inserted into the fixed seat 3, at the same time, the corresponding positioning blocks 12 are inserted into the positioning grooves 13, which is convenient for positioning the position of the mounting column 4 and facilitating the fixing of the mounting column 4. Through the provided mounting holes 15, it is convenient to install the whole.

[0030] Working principle: During use, by pressing the two first limiting blocks 11, the two first limiting blocks 11 drive the two sliders 9 to contract into the two placement grooves 8 respectively. At the same time, the first return spring 10 starts to contract due to the extrusion of the two sliders 9. Subsequently, the mounting column 4 is inserted into the fixed seat 3, and at the same time, the corresponding positioning blocks 12 are inserted into the positioning grooves 13, and the mounting column 4 is moved downward. When the positions of the two first limiting blocks 11 and the two limiting grooves 7 correspond, under the elastic force of the first return spring 10, the two first limiting blocks 11 are driven to pop out from the two limiting grooves 7 respectively, thereby limiting and fixing the mounting column 4, making it convenient to install the reamer head 5. Then, by rotating the two rotating caps 604, the two screw rods 603 respectively drive the two second limiting blocks 606 to move relatively through the two movable sleeves 605, so that the two second limiting blocks 606 move to the upper end of the mounting column 4, and the upper end of the mounting column 4 is limited by the two second limiting blocks 606, preventing the mounting column 4 from detaching from the fixed seat 3 during the rotational machining of the reamer head 5, and further improving the stability of the installation connection. At the same time, through the provided shock absorption mechanism 2, when the reamer head 5 is in the machining process, the machine will generate a certain vibration. When the support plate 202 is subjected to the vibration, it will squeeze the damper 201. At the same time, under the action of the U-shaped block 206 and the connecting rod 207, the moving plate 205 is driven to move, and the second return spring 208 starts to contract due to the movement of the moving plate 205. Under the elastic force of the second return spring 208 and the damping effect of the damper 201, it plays a role in buffering and shock absorption, enabling the reamer head 5 to maintain a certain stability and improving the machining quality.

[0031] As described above, it is only the preferred embodiment of the present utility model, and does not impose other forms of limitations on the present utility model. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
