[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Depend on Figures 1-6 As shown, this utility model includes an installation sleeve 1, a connecting seat 11 fixedly connected to the upper surface of the installation sleeve 1, a reamer body 2 movably installed on the upper end of the connecting seat 11, a rotating ring 3 rotatably sleeved on the outer wall of the connecting seat 11, a fixing component for fixing the reamer body 2 is provided inside the rotating ring 3, and a positioning component for positioning the fixing component is also provided inside the rotating ring 3.

[0016] The top of the connecting seat 11 is provided with a sliding groove 12, and two sets of slots 13 are symmetrically provided at the bottom of the inner wall of the sliding groove 12. The two sets of blocks 23 are slidably connected to the inner wall of the slots 13. The slots 13 and the blocks 23 cooperate to position the reamer body 2.

[0017] A first spring 14 is fixedly connected to the bottom of the inner wall of the slide 12, a connecting block 15 is fixedly connected to the top of the first spring 14, a positioning rod 16 is fixedly connected to the upper surface of the connecting block 15, and a positioning groove 22 matching the positioning rod 16 is opened at the bottom of the reamer body 2.

[0018] A limiting plate 21 is fixedly sleeved on the outer wall of the reamer body 2, which contacts the top of the connecting seat 11.

[0019] When it is necessary to install the reamer body 2, the bottom end of the reamer body 2 is inserted into the inner wall of the slide groove 12, and the positioning rod 16 is inserted into the inner wall of the positioning groove 22 to position the reamer body 2. Then, downward pressure is applied to the reamer body 2. At this time, the connecting block 15 squeezes the first spring 14. The force of the first spring 14 can limit the reamer body 2 and prevent the reamer body 2 from moving. When the limiting plate 21 is tightly attached to the connecting seat 11, the reamer body 2 is rotated to engage the locking block 23 into the inner wall of the locking groove 13, thereby facilitating the installation of the reamer body 2.

[0020] The fixing assembly includes a first magnetic block 31 symmetrically fixedly installed on the inner wall of the rotating ring 3. A fixing rod 34 for fixing the reamer body 2 is slidably connected to the inner wall of the rotating ring 3. A second magnetic block 32 located inside the rotating ring 3 is fixedly installed at one end of the fixing rod 34. A second spring 35 is sleeved on the outer wall of the fixing rod 34 and fixedly connected to the second magnetic block 32 and the outer wall of the connecting seat 11. (Both the first magnetic block 31 and the second magnetic block 32 are positive magnetic blocks. According to the principle of "like poles repel" and "opposite poles attract" between magnets, the first magnetic block 31 and the second magnetic block 32 will generate a repulsive force.) Two sets of fixing blocks 4 are symmetrically fixedly connected to the outer wall of the connecting seat 11 inside the rotating ring 3. The fixing blocks 4 are staggered with the first magnetic block 31. Two sets of mounting blocks 42 are fixedly connected to the inner wall of the rotating ring 3, which are also staggered with the first magnetic block 31. Spring retaining beads 43 are fixedly connected to one side surface of the two sets of mounting blocks 42. Two sets of fixing grooves 41 that match the spring retaining beads 43 are opened on the surface of the fixing blocks 4. (In normal state, the spring retaining beads 43 are engaged with one set of fixing grooves 41. When the first magnetic block 31 and the second magnetic block 32 are aligned, the spring retaining beads 43 just fit into the inner wall of the other set of fixing grooves 41.) Two sets of locking blocks 23 are symmetrically fixed to the outer wall of the bottom end of the reamer body 2. The surface of the locking blocks 23 is provided with slots 24 that match the fixing rod 34.

[0021] After the reamer body 2 is positioned, the rotating ring 3 is rotated, which drives the first magnetic block 31 to rotate. When the spring retainer 43 moves from one set of fixing slots 41 to the inner wall of another set of fixing slots 41, the snapping sensation during engagement will alert the operator. At this time, the first magnetic block 31 is aligned with the second magnetic block 32. Simultaneously, the fixing rod 34 moves to the inner wall of the slot 24 on the retainer block 23 with the cooperation of the first magnetic block 31 and the second magnetic block 32, thus fixing and installing the reamer body 2.

[0022] Two sets of limiting rods 36 are symmetrically fixedly connected to the outer wall of the connecting seat 11 inside the rotating ring 3. Connecting rods 33 are fixedly connected to both sides of the two sets of second magnetic blocks 32. A dovetail block 331 is fixedly connected to one side surface of the connecting rod 33. A dovetail groove 361 matching the dovetail block 331 is opened on one side surface of the two sets of limiting rods 36. Through the mutual cooperation of the dovetail block 331 and the dovetail groove 361, the fixing rod 34 can move in parallel and just insert into the inner wall of the slot 24.

[0023] Working principle: When the reamer body 2 needs to be installed, the bottom end of the reamer body 2 is inserted into the inner wall of the slide groove 12. The reamer body 2 is positioned by the positioning rod 16 in conjunction with the positioning groove 22. A downward pressure is applied to the reamer body 2, and the connecting block 15 squeezes the first spring 14. When the limiting plate 21 contacts the top of the connecting seat 11, the reamer body 2 is rotated clockwise. The reamer body 2 is positioned by the slot 13. Then, the rotating ring 3 is rotated. The rotating ring 3 drives the spring retaining ball 43 to rotate through the mounting block 42. When the spring retaining ball 43 moves from the inner wall of one set of fixing grooves 41 to the inner wall of another set of fixing grooves 41, the first magnetic block 31 is just aligned with the second When the magnetic blocks 32 are aligned, the fixing rod 34, under the mutual repulsion of the first magnetic block 31 and the second magnetic block 32, inserts into the inner wall of the slot 24 on the card block 23 to fix the reamer body 2. Then, it is installed on the lathe through the mounting sleeve 1, and the reamer body 2 can be used. When it is necessary to disassemble the reamer body 2, simply rotate the rotating ring 3 in the opposite direction to separate the first magnetic block 31 from the second magnetic block 32. The fixing rod 34 can then be reset under the force of the second spring 35 and separated from the slot 24. Then, rotate the reamer body 2 counterclockwise to separate the reamer body 2 from the connecting seat 11 for disassembly. The operation is simple and convenient.
