[0002] A tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. A machining tool generally includes a tool holder and a machining head. The machining head is locked to the tool holder by a locking piece for easy replacement. According to the patent document entitled "A machining tool with a protective structure" with the authorization announcement number CN204148595U, the tool holder is locked in the assembly groove of the tool holder by two locking pieces. In this way, the tool holder extends out of the tool holder, and the machining edge of the tool holder is at the front end to process the workpiece. When the machining is completed and the tool holder is no longer needed, one of the locking pieces is removed and the other locking piece is loosened. In this way, the tool holder can be rotated around the loosened locking piece and rotated into the assembly groove in the middle of the tool holder. In this way, the tool holder is locked in the assembly groove in the middle of the tool holder by inserting the locking piece for storage, thereby protecting the machining edge on the tool holder. This solves the problem of damage to the machining edge caused by shaking of the tool holder in the tool box in the prior art, thereby extending the service life of the tool. However, the following defects still exist:

[0003] The cutting head is rotated into the assembly slot in the middle of the handle for storage by operating the locking member, and the locking member adopts a locking screw or bolt, so a special tool is needed, which is inconvenient to use. Utility Model Content

[0026] Specifically, by Figure 4-6The adjustment mechanism 2 includes two L-shaped round rods 201 symmetrically fixed in the knife cylinder 1, and the outer sides of the two L-shaped round rods 201 are movably connected with the same slide plate 203. The mounting frame 3 is fixed to the outer side of the slide plate 203. The bottom of the mounting frame 3 is fixedly connected with a tooth plate 2010. The inner plate 204 is fixedly installed inside the knife cylinder 1. The outer side of the inner plate 204 is rotatably connected to a drive shaft 206 located below the tooth plate 2010. The drive shaft 206 extends away from one end of the inner plate 204. The outer side of the knife cylinder 1 is fixedly connected to the hand wheel 207, the outer side of the drive shaft 206 is fixedly installed with a gear 205, the gear 205 is meshed with the tooth plate 2010, the outer sides of the two L-shaped round rods 201 are fixedly sleeved with the limit ring 1 202, the side of the slide 203 away from the mounting frame 3 is in contact with the two limit rings 1 202, the outer sides of the two L-shaped round rods 201 are fixedly sleeved with the limit ring 2011, and the two limit rings 2011 are both located near the mounting plate 203. On one side of the frame 3, the outer side of the inner plate 204 is fixedly connected with a U-shaped round rod 2012, and the outer side of the U-shaped round rod 2012 is movably connected with a movable plate 2015. Two springs 2014 are symmetrically fixedly connected between the movable plate 2015 and the inner plate 204. Both springs 2014 are sleeved on the outer side of the U-shaped round rod 2012. The top of the movable plate 2015 is fixedly connected with a positioning column 2013. The outer side of the mounting frame 3 is provided with a positioning hole 1 2016 and a positioning hole 2 2017. The inner diameter of the first positioning hole 2016 and the second positioning hole 2017 is the same, the positioning post 2013 is inserted into the second positioning hole 2017, the bottom of the movable plate 2015 is fixedly connected to the connecting post 209, and the end of the connecting post 209 away from the movable plate 2015 is fixedly connected to the pressing plate 208. A circular hole 9 is provided on the outer side of the knife cylinder 1, and the pressing plate 208 is located in the circular hole 9. The circular hole 9 is provided to accommodate and protect the pressing plate 208 to prevent the pressing plate 208 from moving due to collision;

[0027] When in use, first press the pressing plate 208, and drive the movable plate 2015 to slide along the U-shaped rod 2012 through the connecting column 209. At this time, the two springs 2014 are compressed, and drive the positioning column 2013 to move until it moves out of the positioning hole 2017. Then rotate the hand wheel 207 counterclockwise to drive the drive shaft 206 to rotate, and drive the gear 205 to rotate. Since the gear 205 is meshed with the tooth plate 2010, it drives the mounting frame 3 and the cutter head 4 to move. At the same time, the slide plate 203 slides along the two L-shaped rods 201. When the slide plate 203 abuts against the two limit rings 2011, the cutter head 4 moves to the outside of the knife cylinder 1, and then releases the pressing plate 208. At this time, the movable plate 2015 slides along the U-shaped round rod 2012 under the action of the elastic force of the two springs 2014, and drives the positioning column 2013 to move until it is inserted into the positioning hole 1 2016, and the position of the cutter head 4 is fixed, and the workpiece can be processed. When the hand wheel 207 is rotated clockwise, the mounting frame 3 and the cutter head 4 are driven to move into the interior of the knife cylinder 1 until the slide plate 203 abuts against the two limit rings 1 202, and then the positioning column 2013 is inserted into the positioning hole 2 2017, and finally the cutter head 4 is fixed inside the knife cylinder 1 for storage and protection.

[0028] Specifically, by Figure 2-3 It is given that the inner wall of the knife cylinder 1 is provided with an internal thread 6, and the interior of the knife cylinder 1 is provided with a threaded column 7. The external thread on the threaded column 7 is adapted to the internal thread 6, and the threaded column 7 is threadedly connected to the knife cylinder 1 through the internal thread 6. The interior of the knife cylinder 1 is fixedly connected with an abutment ring 10, and the threaded column 7 abuts against the abutment ring 10. The side of the threaded column 7 away from the abutment ring 10 is fixedly connected with an auxiliary block 5. By setting the auxiliary block 5, it is convenient to drive the threaded column 7 to rotate. The side of the threaded column 7 away from the auxiliary block 5 is fixedly connected with a protective tube 11, and the protective tube 11 is sleeved on the outside of the cutter head 4.

[0029] When the cutter head 4 is housed inside the cutter barrel 1, the threaded column 7 is first placed inside the cutter barrel 1, and then the threaded column 7 is rotated clockwise through the auxiliary block 5. Since the threaded column 7 is threadedly connected to the cutter barrel 1 through the internal thread 6, the threaded column 7 moves while rotating until the threaded column 7 abuts against the abutment ring 10, and the protective tube 11 is put on the outside of the cutter head 4, and finally the cutter head 4 is further protected.
