Example (b):

referring to fig. 1-7, the utility model discloses a but vice knife rest of many sizes cutter arbor of adaptation, including vice knife rest body 1, wear to be equipped with reducing sleeve 2 through clamp bolt is fixed in the vice knife rest body 1, and reducing sleeve 2 comprises solid fixed cylinder 3 and solid fixed cylinder 3 opening part bearing rotation carousel 4 that sets up.

The reducing sleeve 2 is internally provided with a fastening component 5. The fastening component 5 comprises a thread cylinder 51 and four limiting rods 54, the thread cylinder 51 is arranged in the reducing sleeve 2 in a penetrating mode, the thread cylinder 51 is connected with the fixed cylinder 3 in a rotating mode, the thread cylinder 51 is fixedly connected with the rotary disc 4, and four pressing blocks 52 are connected with the thread cylinder 51 in an internal thread mode. The threaded cylinder 51 is positioned in the fixed cylinder 3 and is in a circular truncated cone shape, and the pressing block 52 is attached to the inner wall of the threaded cylinder 51. The inner wall of the threaded cylinder 51 is attached to the pressing block 52, so that the threaded cylinder 51 always has pushing force on the pressing block 52.

One side of the pressing block 52 far away from the threaded cylinder 51 is provided with an arc surface, a soft pad 55 is fixedly connected to the arc surface of the pressing block 52, a plurality of conical blocks 56 are arranged in the soft pad 55 in a sliding and penetrating manner, and one end of each conical block 56, which is positioned outside the corresponding soft pad 55, is fixedly connected with the corresponding pressing block 52. The friction force between the pressing block 52 and the tool shank is increased through the mutual matching of the soft cushion 55 and the conical block 56.

Four sliding grooves 53 are formed in the positions, corresponding to the four pressing blocks 52, of the inner wall of the threaded cylinder 51, one ends of the four limiting rods 54 are fixedly connected with the four pressing blocks 52 respectively, and the other end of each limiting rod 54 is inserted into the corresponding sliding groove 53. Along with the sliding of the limiting rod 54 in the sliding groove 53, the pressing block 52 is always attached to the threaded cylinder 51, the rotating disc 4 is rotated when the tool shank is fixed, so that the threaded cylinder 51 is driven to rotate, the four pressing blocks 52 are pushed to move, and meanwhile, the tool shank is extruded inwards to be fixed, and the device is simple in operation.

A positioning component 6 is arranged between the peripheral wall of the fixed cylinder 3 and the top end of the rotary disc 4. Locating component 6 includes fixed block 62, and a plurality of draw-in grooves 61 have been seted up on the top of carousel 4, and fixed block 62 is fixed to be located on the periphery wall of solid fixed cylinder 3, and spacing groove 63 has been seted up to the position department that corresponds draw-in groove 61 in the fixed block 62, and slides in the spacing groove 63 and wears to be equipped with locating lever 64, and the bottom of locating lever 64 is the hemisphere setting. The locating plate 66 that relative fixedly connected with shape was the setting of semicircle in the spacing groove 63, clearance fit between two locating plates 66 and the locating lever 64, two sliders 67 of relative fixedly connected with on the periphery wall of locating lever 64, and two sliders 67 all are located the spacing groove 63. The positioning rod 64 can be fixed in the fixed position by the mutual engagement between the positioning plate 66 and the slider 67, so that the positioning rod 64 is not inserted into the slot 61.

A spring 65 is arranged between the positioning rod 64 and the fixing block 62, and two ends of the spring 65 are fixedly connected with the fixing block 62 and the positioning rod 64 respectively. After the tool holder is fixed, the spring 65 pushes the positioning rod 64 to be inserted into the corresponding clamping groove 61, so that the fixing cylinder 3 and the rotating disc 4 are limited to prevent the rotating disc 4 from rotating, and the pressing block 52 cannot loosen the extrusion of the tool holder.

Insert the cutter arbor in reducing sleeve 2 when the installation cutter arbor, then rotate carousel 4 and control fastening components 5 and fix the cutter arbor at reducing sleeve 2, position between fixed carousel 4 of locating component 6 and the solid fixed cylinder 3 at last, make unable rotation between solid fixed cylinder 3 and the carousel 4, thereby make the stable fixing of handle of a knife on the knife rest body, it is fixed through fastening components 5 between handle of a knife and the reducing sleeve 2, fastening components 5 can carry out the adjustment that corresponds according to the diameter of handle of a knife, make reducing sleeve 2 can fix the handle of a knife of diameter in the certain limit, thereby still change the diameter scope of the fixed handle of a knife of fastening components 5 through compression bolt 2.

The implementation principle of the above embodiment is as follows: when the device is used, a proper reducing sleeve 2 is selected to be inserted into the mounting hole of the auxiliary tool rest body 1 and fixed through a pressing bolt, then the tool shank is inserted into the reducing sleeve 2, the rotary disc 4 is rotated to drive the threaded barrel 51 to rotate, the limiting rod 54 and the sliding groove 53 are matched to limit and push the pressing block 52 to move along the inner wall of the threaded barrel 51, and the four pressing blocks 52 are extruded towards the tool shank together, after the soft pad 55 is contacted with the tool shank, the soft pad 55 is pierced out of the soft pad 55 along with the deformed conical block 56 of the soft pad 55 and is extruded with the tool shank mutually, the tool shank is fixed in the border sleeve, the tool shank is fixed on the auxiliary tool rest body 1, after the tool shank is fixed, the rotary positioning rod 64 pushes the positioning rod 67 to penetrate between the two positioning plates 66 along with the rotary spring 65 of the positioning rod 64, and is inserted into the clamping groove 61 along with the positioning rod 64, and the fixed barrel 3 and the rotary disc 4 are limited, so that the rotary disc 4 is prevented from continuing to rotate.

When the tool holder is detached, the positioning rod 64 is pulled and rotated, the sliding block 67 penetrates through a gap between the two positioning plates 66, the positioning rod 64 continues to rotate for a certain angle, the sliding block 67 and the positioning plates 66 are clamped with each other, the positioning rod 64 is fixed in the fixing block 62, the limiting state between the rotary disc 4 and the fixing barrel 3 is relieved, the rotary disc 4 is rotated reversely, the fiber state of the tool holder is relieved from the pressing block 52, and the tool holder is directly pulled out from the reducing sleeve 2 to be replaced.

The embodiment of this embodiment is the preferred embodiment of the present invention, not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
