Detailed implementation manners

[0018] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: an adjustable milling cutter handle, including a mounting base 1, a support column 2, a milling cutter handle main body 3, a mounting mechanism 4, a fixed seat 5, a rotating shaft 6, a rotating disk 7 and a fixing bolt 8. A support column 2 is provided on the mounting base 1, and a rotating disk 7 is further assembled at the top of the support column 2. A rotating shaft 6 is installed in the middle of the rotating disk 7. The top of the rotating shaft 6 is connected to the milling cutter handle main body 3. And a mounting mechanism 4 is provided on the milling cutter handle main body 3. The fixed seat 5 is installed on the top of the milling cutter handle main body 3 through the mounting mechanism 4. The mounting mechanism 4 includes a clamping block 401, a fixing rod 402, a bearing seat 403, a bearing 404, a sleeve rod 405, an insertion rod 406, an external box 411, a pull rope 412, a control bolt 413 and a limiting ring 414. The clamping blocks 401 are arranged at the left and right ends of the milling cutter handle main body 3, and a fixing rod 402 is further arranged at the middle position between the clamping blocks 401 at the left and right ends. The bottom of the clamping block 401 is assembled with a bearing 404, and the bearing 404 is arranged on the bearing seat 403. Insertion rods 406 are further added at the bottom positions of the clamping blocks 401 at the left and right ends, and the insertion rods 406 are connected to the sleeve rod 405. The limiting ring 414 is sleeved on the periphery of the clamping block 401, and a plurality of pull ropes 412 are arranged in the limiting ring 414. The pull ropes 412 are connected to the control bolt 413 in the external box 411.

[0020] As the first embodiment of the present utility model: The mounting base 1 is fixedly connected to the milling cutter device by arranging a plurality of fixing bolts 8 on the surface. This design uses the fixing bolts 8 to fix and disassemble the mounting base 1, with a simple structure and convenient replacement. The sleeve rod 405 is installed inside the milling cutter handle main body 3, and the sleeve rod 405 matches the size of the insertion rod 406. This design realizes the telescoping of the insertion rod 406 by setting the sleeve rod 405, which helps the movement of the clamping blocks 401 on both sides. The bottom of the rotating shaft 6 is welded to the rotating disk 7 and the top is also connected to the bottom of the milling cutter handle main body 3. By adding the rotating shaft 6, this design helps to adjust the direction of the milling cutter handle and improve the practical efficiency of the milling cutter during processing. The bearing seat 403 is fixed on the bottom surface of the milling cutter handle main body 3, and the bearing seat 403 and the bearing 404 are connected by a snap connection. Adding the bearing 404 to the clamping blocks 401 at the bottom of the milling cutter handle main body 3 helps to improve the flexibility of the clamping blocks 401 on both sides. The pull ropes 412 on both sides inside the limiting ring 414 are both tied to the control bolt 413, and the control bolt 413 is screwed externally on the outer box 411. Adding the limiting ring 414 provides limiting protection for the clamping blocks 401, which is beneficial to further ensure the safety and firmness of the milling cutter installed on the milling cutter handle.

[0021] As the second embodiment of the present utility model: When the staff replaces the milling cutter in the milling machine equipment, first, the control bolt 413 on the limiting ring 414 is rotated counterclockwise. The counterclockwise rotation of the control bolt 413 will loosen the pull rope 412 inside the limiting ring 414, so that the limiting ring 414 will expand. After removing the limiting ring 414, the staff can expand the clamping blocks 401 on both sides through the bearings 404 arranged at the bottom of the clamping blocks 401. In this way, the insertion rod 406 at the bottom of the clamping blocks 401 will be inserted into the sleeve rod 405 at the bottom of the milling cutter handle main body 3 due to rotation. When the clamping blocks 401 on both sides are expanded, the fixing seat 5 for fixing the milling cutter can be removed from the milling cutter handle main body 3. After replacing the milling cutter, similarly, the fixing seat 5 is put back on the top of the milling cutter handle main body 3. After the clamping blocks 401 on both sides clamp the fixing seat 5 again, the insertion rod 406 at the bottom of the clamping blocks 401 will extend out of the sleeve rod 405. The staff can again sleeved the limiting ring 414 and twist the control bolt 413 clockwise. The pull rope 412 inside the limiting ring 414 will tighten, so that the limiting ring 414 will clamp the clamping blocks 401 on both sides of the milling cutter handle main body 3, playing a role of fixing and limiting.
