The first embodiment is as follows: referring to fig. 1 to 7, a cutting tool 100 includes a tool shank 200, a cutting head 300, and a first pivot structure 400 pivotally connecting the tool shank 200 and the cutting head 300. The tool holder 200 is provided with an accommodating cavity 201 for accommodating the tool bit 300, and the accommodating cavity 201 corresponds to the tool bit 300. When the tool 100 is not in use, the tool bit 300 can be rotated along the first pivot structure 400 and then received in the receiving cavity 201.

The tool bit 300 comprises a shell 1, a tool rest 2 contained in the shell 1, a tool storage space 3 arranged on one side of the tool rest 2, a plurality of blades 4 locked and supported on one side surface of the tool rest 2 adjacent to the tool storage space 3, and a tool cover 5 covering the tool storage space 3. The cutter storage space 3 extends outwards to the shell 1 and is parallel to one side surface of the cutter frame 2 to form a cutter storage opening 31 matched with the plane outer contour of the cutter 4, and the cutter cover 5 is arranged on the cutter storage opening 31 in a covering mode. The blades 4 include a first blade 41 and at least a second blade 42 parallel to the first blade 41 and stacked in the blade storage space 3, in this embodiment, five blades 4 can be stored in the blade storage space 3, and each blade 4 is parallel to each other and stacked. The blade 4 is provided at its upper edge with a blade locking portion 43 for locking with the blade holder 2.

One end of the knife cover 5 is pivotally connected to the knife head 300 through a second pivot structure (not shown), and a through hole 51 is formed at one end of the knife cover 5 so that the second pivot structure can pass through. The second pivot structure is disposed at one side edge of the knife cover 5, and the knife cover 5 freely rotates around the second pivot structure to open or close the knife cover 5 relative to the knife storage opening 31. Of course, in other embodiments, the second pivot may be disposed at the middle position or other positions of the knife cover 5, as long as the knife storage edge 31 can be opened after the knife cover 5 is rotated away. It should be noted that, in the present invention, the first pivot structure 400 and the second pivot structure are the same pivot structure 400, and in this embodiment, the first pivot structure 400 is a pivot axis, which means that all embodiments of the present invention take this as an example. The knife cover 5, the first shell 11, the second shell 12 and the knife handle 200 are all sleeved on the first pivot structure 400, and the four are coaxial. When the knife cover 5 is covered on the housing 1, the knife cover 5, the first housing 11 and the second housing 12 are an integral body and can rotate freely along the first pivot structure 400.

The housing 1 includes a first housing 11 and a second housing 12 fastened and fixed to each other, and the first housing 11 and the second housing 12 are both provided with through holes (not labeled) for the first pivot structure 400 to pass through, so as to realize the pivot connection with the tool holder 200. The knife edge 31 is formed on one side of the first housing 11, and the knife cover 5 is disposed on one side of the first housing 11 away from the second housing 12, that is, on the outer side of the first housing 11.

The first housing 11 includes a first wall 111, a second wall 112, a third wall 113, a fourth wall 114 connecting the first wall and the second wall, and a knife storage space 3 and a knife storage edge 31 surrounded by the first wall, the second wall, the third wall, and the fourth wall. The thicknesses of the first and

third walls

111, 113 are greater than the thicknesses of the second and

fourth walls

112, 114, the storage blade 31 extends in the direction of the second and

fourth walls

112, 114 and penetrates the second and

fourth walls

112, 114, and the through hole of the first housing 11 is formed in the fourth wall 114. The knife storage edge 31 is located at one side of the first pivot structure 400, the knife storage edge 31 is communicated with the knife storage space 3, and the knife cover 5 is covered on the knife storage edge 31 in an outer contour manner.
