[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] See Figures 1 to 9 One embodiment of this application provides a cutting tool system, which may include a main body 1 and scissor heads 2 and cutting heads 3 that can be respectively connected to the main body 1.

[0032] The main body 1 may include a main body 11 and a handle 12 connected to the main body 11. The main body 1 is generally tubular, and a drive component is fixed inside to provide driving force to the overall system. In this embodiment, the drive component is a motor. The upper surface of the main body 1 has a main power switch for power switch control. The handle 12 has a receiving space for housing a battery to power the motor. The receiving space also houses a control circuit board and a switch connected to the control circuit board. The handle 12 also has a trigger disposed opposite to the switch. The trigger, switch, and control circuit board can control the operation of the motor, further realizing the control of the shearing tool system. In other embodiments, the control circuit board may also be housed in the main body 11. In this embodiment, the main body 11 and the handle 12 can be rotatably connected. The main body 11 and / or the handle 12 may have an annular first recess, and the handle 12 and / or the main body 11 may have an annular first protrusion opposite to the aforementioned first recess. The first recess engages with the first protrusion, allowing relative rotation between the handle portion 12 and the main body portion 11. The main body 1 also includes a limiting mechanism comprising a button, a stop block, and a spring. The button is connected to the stop block and is pushed by the spring. The first protrusion has a limiting groove. The stop block, pushed by the spring, is engaged in the limiting groove, thus limiting the relative position of the handle portion 12 and the main body portion 11. When it is necessary to adjust the relative position of the handle portion 12 and the main body portion 11, pressing the button disengages the stop block from the limiting groove, allowing for rotational adjustment.

[0033] See details Figures 8 to 9The main body 11 also has a tool head mating part, which includes a mating bracket 113, a locking member 114 mounted on the mating bracket 113, and an elastic member (such as a spring) that elastically supports the locking member 114. The mating bracket 113 includes a base 1131, a limiting part 1132 extending from the outer periphery of the base 1131, and a positioning space 1133 protruding axially from the base 1131. The base 1131 is provided with a mounting hole 11330 for mounting the main body 11 onto the drive component housing by screws. The limiting part 1132 can initially limit the movement range of the locking member 114 (the locking member 114 has a corresponding fit) to prevent functional failure. The positioning space 1133 is used to accommodate one end of the elastic member to achieve elastic support for the locking member 114. The limiting part 1132 and the positioning space 1133 are paired and there are two pairs, and the two pairs of limiting parts 1132 and positioning spaces 1133 are centrally symmetrically arranged. The base 1131 also includes a central clearance hole for the output shaft of the drive component to pass through and output power outward. The locking member 114 has a pressing part 1141, guide parts 1142 disposed on both sides of the pressing part 1141, and a barb part 1143 disposed at the free end of the pressing part 1141. The main body 11 also has a guide groove for cooperating with the guide part 1142 to guide the locking member 114 and prevent functional failure. The barb part 1143 can engage with the scissor head 2 or the cutting head 3 to achieve a stable engagement between the main body 1 and the scissor head 2 or the cutting head 3. The outer side of the barb part 1143 has a smooth transition shape to achieve smooth engagement with the scissor head 2 or the cutting head 3. The tool head engagement part also has a first positioning part 115.

[0034] The scissor head 2 has a scissor housing 21, an eccentric mechanism disposed within the scissor housing 21, a movable blade connected to the eccentric mechanism, and a fixed blade fixed within the scissor housing 21. The scissor housing 21 also has a first mating protrusion 211, which can be stably secured by a barb portion 1143, achieving a stable fit between the scissor head 2 and the main body 1. The scissor housing 21 is provided with a second positioning portion 212. The second positioning portion 212 cooperates with the first positioning portion 115 to achieve circumferential positioning.

[0035] The cutting head 3 includes a cutting housing 31, a planetary gear set and a steering gear mechanism disposed within the cutting housing 31, and a cutting blade. The cutting housing 31 also has a second mating protrusion 311, which can be stably secured by a barb portion 1143, achieving a stable fit between the cutting head 3 and the main body 1. The cutting housing 31 is provided with a third positioning portion 312. The third positioning portion 312 cooperates with the first positioning portion 115 to achieve circumferential positioning.

[0036] When it is necessary to mate the scissor head 2 or the cutting head 3 with the main body 1, the scissor head 2 or the cutting head 3 is aligned with the tool head mating part of the main body 11 and pushed. The first mating protrusion 211 or the second mating protrusion 311 pushes against the barb part 1143, causing the locking member 114 to resist the elastic force of the elastic member. The barb part 1143 gives way to the first mating protrusion 211 or the second mating protrusion 311. When the first mating protrusion 211 or the second mating protrusion 311 passes over the barb part 1143, the elastic force of the elastic member pushes against the locking member 114, causing the barb part 1143 to lock the first mating protrusion 211 or the second mating protrusion 311, thereby achieving a stable fit between the main body 1 and the scissor head 2 or the cutting head 3.

[0037] When it is necessary to disassemble the scissor head 2 or the cutting head 3 from the main body 1, press the pressing part 1141 of the locking member 114, causing the locking member 114 to resist the elastic force of the elastic member, and the barb part 1143 to give way to the first mating protrusion 211 or the second mating protrusion 311, and pull out the scissor head 2 or the cutting head 3.

[0038] For further details, please refer to [link / reference]. Figure 5 The main body 1 has an output shaft 13 and an external hexagonal prism 14 that is interference-fitted to the output shaft 13. The scissor head 2 and the cutting head 3 both have a drive shaft 4 and a bearing 5 that supports the drive shaft 4. The drive shaft 4 has an internal hexagonal prism 41. The external hexagonal prism 14 of the main body 1 cooperates with the internal hexagonal prism 41 to realize the transmission of power.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
