[0022] See also Figures 1 to 9 An embodiment of the present application provides a shearing tool system, which may include a main body 1 and a scissor head 2 and a cutting head 3 that can be respectively matched with the main body 1.

[0023] 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 tubular in shape, and a driving component is fixed inside the main body 1 to provide driving force for the overall system. In this embodiment, the driving component is a motor. The upper surface of the main body 1 has a main power switch to realize power switch control. The handle 12 has a receiving space for accommodating batteries to power the motor. The receiving space also accommodates a control circuit board and a switch connected to the control circuit board. The handle 12 also has a trigger arranged opposite to the switch. The trigger, switch and control circuit board can realize the control of the motor operation and further realize the control of the shearing tool system. In other embodiments, the control circuit board can also be placed 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 can be provided with a first annular recessed portion, and the handle 12 and / or the main body 11 can be provided with a first annular protruding portion relative to the aforementioned first recessed portion. The first recessed portion is engaged with the first raised portion to realize relative rotation of the handle portion 12 and the main body 11. The main body 1 also includes a limiting mechanism, which includes a button, a stopper and a spring. The button is connected to the stopper and is pushed by the spring. The first raised portion is provided with a limiting groove. The stopper is stopped in the limiting groove under the push of the spring to realize relative limitation of the handle portion 12 and the main body 11. When the relative position of the handle portion 12 and the main body 11 needs to be adjusted, the button is pressed to disengage the stopper from the limiting groove, and the rotation adjustment position can be realized.

[0024] For details, please refer to Figures 8 to 9The main body 11 also has a tool head matching part, which includes a matching bracket 113, a locking piece 114 mounted on the matching bracket 113, and an elastic piece (such as a spring) that elastically supports the locking piece 114. The matching 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 from the base 1131 in the axial direction. The base 1131 is provided with a mounting hole 11330, which is used to mount the main body 11 on the driving component housing by screws. The limiting part 1132 can preliminarily limit the range of motion of the locking piece 114 (the locking piece 114 has a corresponding fit) to avoid functional failure. The positioning space 1133 is used to accommodate one end of the elastic piece to achieve elastic support for the locking piece 114. The limiting part 1132 and the positioning space 1133 are arranged in pairs, and there are two pairs, and the two pairs of limiting parts 1132 and positioning spaces 1133 are arranged in a central symmetric manner. The base 1131 also includes a centrally located clearance hole for the output shaft of the driving component to pass through so as to output power outward. The locking member 114 includes a pressing portion 1141, a guide portion 1142 disposed on both sides of the pressing portion 1141, and a barb portion 1143 disposed at the free end of the pressing portion 1141. The main body 11 also includes a guide groove for cooperating with the guide portion 1142 to guide the locking member 114 and avoid functional failure. The barb portion 1143 can be snap-fitted with the scissors head 2 or the cutting head 3 to achieve stable cooperation between the main body 1 and the scissors head 2 or the cutting head 3. The outer side of the barb portion 1143 is in a smooth transition shape to achieve smooth coupling with the scissors head 2 or the cutting head 3. The tool head coupling portion also includes a first positioning portion 115.

[0025] The scissor head 2 comprises a scissor housing 21, an eccentric mechanism disposed in the scissor housing 21, a movable blade connected to the eccentric mechanism, and a fixed blade fixed in the scissor housing 21. The scissor housing 21 also comprises a first mating protrusion 211, which can be stably fixed by the barb 1143 to achieve stable mating 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.

[0026] The cutting head 3 has a cutting housing 31, a planetary gear set and a steering gear mechanism and a cutting blade arranged in the cutting housing 31. The cutting housing 31 also has a second mating protrusion 311, and the second mating protrusion 311 can be stably fixed by the barb 1143 to achieve stable matching 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.

[0027] When the scissors head 2 or the cutting head 3 needs to be matched with the main body 1, the scissors head 2 or the cutting head 3 is aligned with the tool head matching portion of the main body 11 and pushed. The first matching protrusion 211 or the second matching protrusion 311 pushes the barb portion 1143, causing the locking member 114 to resist the elastic force of the elastic member, and the barb portion 1143 gives way to the first matching protrusion 211 or the second matching protrusion 311. When the first matching protrusion 211 or the second matching protrusion 311 passes over the barb portion 1143, the elastic force of the elastic member pushes the locking member 114, causing the barb portion 1143 to snap onto the first matching protrusion 211 or the second matching protrusion 311, thereby achieving stable matching between the main body 1 and the scissors head 2 or the cutting head 3.

[0028] When the scissor head 2 or cutting head 3 needs to be disassembled from the main body 1, the pressing portion 1141 of the locking member 114 is pressed, so that the locking member 114 resists the elastic force of the elastic member, and the barb portion 1143 gives way to the first mating protrusion 211 or the second mating protrusion 311, and the scissor head 2 or cutting head 3 is pulled out.

[0029] For further details, see Figure 5 The main body 1 has an output shaft 13 and an outer hexagonal column 14 that is interference-fitted with the output shaft 13. The scissor head 2 and the cutting head 3 both have a transmission shaft 4 and a bearing 5 that supports the transmission shaft 4. The transmission shaft 4 has an inner hexagonal column 41. The outer hexagonal column 14 of the main body 1 cooperates with the inner hexagonal column 41 to achieve power transmission.

To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
