[0030] The outer wall of the handle 1 is provided with a handle sleeve 15, and the handle sleeve 15 is arranged in multiple groups.

[0031] The bottom surface of the installation plate 2 is provided with a protective plate 16, the protective plate 16 is arranged below the handle 1, and the arrangement of the protective plate 16 effectively prevents debris from splashing during use.

[0032] Compression springs 17 are arranged between the multiple groups of pressing plates 8 and the outer wall of the installation sleeve 4, the compression springs 17 are arranged in multiple groups, and the multiple groups of compression springs 17 are used to establish an elastic connection mechanism between the pressing plates 8 and the installation sleeve 4.

[0033] A positioning groove 18 is formed at the top end of the insertion rod 9, a positioning block 19 is installed on the inner top surface of the installation sleeve 4, and the positioning groove 18 and the positioning block 19 are both polygonal.

[0034] Limit rods 20 are arranged on the installation sleeve 4 and are slidingly connected with the sliding sleeve 12, and the sliding cooperation between the multiple groups of limit rods 20 and the sliding sleeve 12 establishes a guide limiting structure.

[0035] In this embodiment, when the cutter body 3 needs to be installed, the cutter body 3 is attached to the inner side of the mounting plate 2, and then the insertion rod 9 is inserted through the cutter body 3 and the mounting plate 2 and inserted into the mounting sleeve 4. The insertion rod 9 is positioned and inserted through the positioning groove 18 and the positioning block 19. After complete insertion, the multiple compression plates 8 are pressed to push the fixing blocks 6 to slide along the sliding groove 5 through the sliding rod 7 and extrude the multiple compression springs 17. The multiple fixing blocks 6 are clamped in the fixing groove 10 arranged on the outer wall of the insertion rod 9. Then the sliding sleeve 12 is pushed to slide along the multiple limiting rods 20 and extrude the push spring 25, and at the same time, the lock sleeve 13 is moved to push the multiple lock rods 14 to be inserted into the lock hole 11 arranged on the bottom surface of the multiple fixing blocks 6, so that the multiple fixing blocks 6 are locked.

[0037] The push spring 25 is connected between the sliding sleeve 12 and the mounting sleeve 4. The push spring 25 is arranged between the sliding sleeve 12 and the mounting sleeve 4. The arrangement of the push spring 25 enables the sliding sleeve 12 to have an automatic rebound function, forming an automatic reset mechanism.

[0038] More specifically, after the locking mechanism completes the locking of the multiple fixing blocks 6, the control sleeve is rotated to drive the multiple support columns 23 to rotate and move, so that the top end of the multiple support columns 23 abuts against the bottom surface of the limiting sleeve 21, so that the sliding sleeve 12 is supported and fixed. At this moment, the sliding position of the sliding sleeve 12 is limited. Conversely, when the rotating sleeve 22 drives the multiple support columns 23 to move to the position of the multiple give-way grooves 24, the top surface of the multiple support columns 23 is separated from the abutment against the bottom surface of the limiting sleeve 21, and the sliding sleeve 12 is pushed by the push spring 25 to release the support of the support column 23 to the limiting sleeve 21, and the unlocking is completed.

[0039] In summary, when the overall device is in use or operation: when the cutter body 3 needs to be installed, the cutter body 3 is attached to the inner side of the mounting plate 2 on one side, and then the insertion rod 9 is inserted through the cutter body 3 and the mounting plate 2 and inserted into the mounting sleeve 4, and is positioned and inserted through the positioning groove 18 and the positioning block 19, after complete insertion, the multiple compression plates 8 are pressed to push the fixing blocks 6 to slide along the sliding groove 5 through the sliding rod 7 and extrude the multiple compression springs 17, so that the multiple fixing blocks 6 are clamped in the fixing groove 10 provided on the outer wall of the insertion rod 9, then the sliding sleeve 12 is pushed to slide along the multiple limiting rods 20 and extrude the push spring 25, at the same time, the lock sleeve 13 is driven to move and push the multiple lock rods 14 to be inserted into the lock hole 11 provided on the bottom surface of the multiple fixing blocks 6, so that the multiple fixing blocks 6 are locked, finally, the sliding sleeve 12 is limited through the limiting mechanism, so that the cutter body 3 can be quickly installed, when different models of cutter bodies 3 need to be replaced, after the limiting mechanism releases the limitation of the sliding sleeve 12, the sliding sleeve 12 is pushed to slide downward through the elastic return of the push spring 25, at the same time, the lock sleeve 13 pulls the multiple lock rods 14 to slide out of the lock hole 11, so that the multiple fixing blocks 6 are unlocked, then the multiple compression plates 8 are pushed to move outward through the elastic return of the multiple compression springs 17, at the same time, the fixing blocks 6 are pulled away from the fixing groove 10 through the sliding rod 7, so that the clamping of the insertion rod 9 is released, then the insertion rod 9 is pulled out of the mounting sleeve 4, so that the cutter body 3 can be disassembled.

[0040] After the locking mechanism completes the locking of the multiple fixing blocks 6, the control sleeve is rotated to drive the multiple support columns 23 to rotate and move, so that the top end of the multiple support columns 23 abuts against the bottom surface of the limiting sleeve 21, so that the sliding sleeve 12 is supported and fixed, at this moment, the sliding position of the sliding sleeve 12 is limited, conversely, when the rotating sleeve 22 drives the multiple support columns 23 to move to the position of the multiple accommodating grooves 24, the top surface of the multiple support columns 23 is separated from the abutment against the bottom surface of the limiting sleeve 21, so that the sliding sleeve 12 is pushed to release the support of the support column 23 to the limiting sleeve 21 through the push spring 25, and then the unlocking is completed.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection mode, which will not be described one by one, in the above, whenever there is a fixed connection, welding is preferred, although the embodiments of the utility model have been shown and described, those skilled in the art can understand that the embodiments can be variously changed, modified, replaced and modified without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
