The side of the first blade portion 1111 opposite to the second blade portion 1121 has a notch shape with a thickness. The side of the second blade portion 1121 relative to the first blade portion 1111 has a tapered convex shape. When the first blade part 1111 and the second blade part 1121 are used for cutting, the first blade part 1111 can be used to stabilize the object to be cut, and the second blade part 1121 can be used to cut the object to be sheared.

Furthermore, the driving assembly 12 includes a driving bracket 121, a gear member 122, a second pivot shaft 123, a pushing member 124 and a first elastic member 125.

The second gear The rotation grooves 1222 of the portion 1221 mesh with the first gear portion 1112 . The pushing member 124 is pivoted on one side of the driving bracket 121 . The pushing member 124 has an arc relative to the inner side of the second gear part 1221 of the gear member 122 , so that the inner side of the pushing member 124 can move against the second gear part 1221 . The first elastic member 125 is disposed on the pushing member 124 . One end of the first elastic member 125 elastically fixes one end of the pushing member 124 to abut against the second gear part 1221 . The second gear part 1221 also has a plurality of pushing grooves 1223, and one end of the pushing member 124 is used to fit into one of the pushing grooves 1223.

Both sides of the combined structure of the bracket 121 simultaneously strengthen the combination of the second cutter body 112, the gear member 122 and the driving bracket 121. The second pivot shaft 123 passes through the two pivot parts 1412 of the limiter 141, the second cutter body 112, the gear member 122 and the drive bracket 121. In this way, the two pivot parts 1412 of the limiter 141 are respectively located on the second pivot axis. Both ends of the rotating shaft 123.

One end of the pushing member 124 is also away from the second gear portion 1221 of the gear member 122 .

At the same time, the push plate 134 is pushed by the other end of the push member 124, and the push plate 134 drives the linking member 131 to pivot downward about the third pivot axis 132 as its axis. The linking member 131 links the fixed column 133 to disengage from the second gear portion 1221 of the gear member 122 , so that the rotation of the gear member 122 is no longer restricted by the fixed column 133 . In addition, the driving bracket 121 has a linkage portion 1211 so that the limiting member 141 will move away from the first gear portion 1112 and the second gear portion 1221 due to the rotation of the driving bracket 121 .

Please refer to FIGS. 9 and 10 together. FIG. 9 is an action diagram 2 of the shearing structure of the present application and a partially enlarged schematic diagram 2 of FIG. 10 .

As shown in the figure, in this embodiment, the driving bracket 121 is pressed inward clockwise, and the first cutter body 111 is pressed inward counterclockwise. The second blade portion 1121 of the second blade body 112 and the first blade portion 1111 of the first blade body 111 are close to each other and shear the object 2 to be cut. The driving bracket 121 drives the pushing member 124 to move, and the other end of the pushing member 124 is separated from the hook member 113 . One end of the pushing member 124 is again elastically fixed by the first elastic member 125 and moves toward the second gear part 1221 of the gear member 122 , so that one end of the pushing member 124 fits into one of the pushing grooves 1223 of the second gear part 1221 One (namely, the first pushing groove 1223A), and one end of the pushing member 124 pushes the gear member 122 to rotate clockwise. The second gear portion 1221 of the gear member 122 rotates counterclockwise in conjunction with the first gear portion 1112 of the first cutter body 111 . In other words, the first cutter portion 1111 of the first cutter body 111 moves toward the second cutter portion of the second cutter body 112 1121 are close to each other and exert force on the object 2 to be sheared.

At the same time, the pushing member 124 pushes the limiting member 141 through the other end of the first elastic member 125, so that the end of the limiting member 141 with the limiting column 142 moves toward the direction between the first gear part 1112 and the second gear part 1221. When the pushing member 124 links the limiting column 142 of the limiting member 141 to be fixed between the first gear part 1112 and the second gear part 1221, the clockwise inward pressing action of the driving bracket 121 is stopped, and the shearing of the first section is completed. cut action.

Based on the above, when the other end of the pushing member 124 is separated from the hook member 113, the other end of the pushing member 124 no longer exerts force on the push plate 134, and the linking member 131 is elastically fixed by the second elastic member 135 again, so that The linking member 131 pivots upward with the third pivot axis 132 as the axis, and the linking member 131 moves toward the gear member 122 . The linking member 131 drives the fixed column 133 and the push plate 134 to move together. The fixed column 133 moves to the rotation path of the second gear part 1221 of the gear member 122, so that the fixed column 133 is locked in the restriction grooves of the second gear part 1221. 1224 (ie, the first limiting groove 1224A) to limit the counterclockwise rotation direction of the gear member 122 .

Please refer to FIG. 13 and FIG. 14 together. FIG. 13 is a partially enlarged schematic diagram 4 of the operation diagram 4 of the shearing structure of the present application and FIG. 14 . As shown in the figure, in this embodiment, the aforementioned steps of opening the shearing structure 1 and then pressing the shearing structure 1 again are repeated. First, open the driving bracket 121 outward again counterclockwise. The driving bracket 121 drives the pushing member 124 to move, and after one end of the pushing member 124 is separated from the first pushing groove 1223A of the second gear part 1221, one end of the pushing member 124 moves downward. The pushing groove 1223 (ie, the second pushing groove 1223B) moves in the direction. The first elastic member 125 further restricts one end of the pushing member 124 from moving against the pushing grooves 1223 of the second gear part 1221, so that one end of the pushing member 124 is fitted into the second pushing grooves 1223B of the pushing grooves 1223. . In addition, the linking portion 1211 of the driving bracket 121 again pushes the end of the restricting member 141 with the restricting post 142 away from the space between the first gear portion 1112 and the second gear portion 1221 .

Furthermore, the driving bracket 121 is pressed clockwise inwards, and one end of the pushing member 124 pushes the second pushing groove 1223B of the gear member 122 to perform a second shearing of the object 2 to be sheared, that is, the second segment of shearing is completed. action. At the same time, the other end of the first elastic member 125 once again drives the end of the limiting member 141 with the limiting column 142 to move and be fixed between the first gear part 1112 and the second gear part 1221 . In other words, the relationship between the first gear part 1112 of the first cutter body 111 and the second gear part 1221 of the gear member 122 is again restricted. In addition, when the gear member 122 is pushed by the pushing member 124 to rotate, the fixing column 133 will Disengaged from the first restricting groove 1224A of the second gear part 1221, the fixing post 133 of the linking member 131 is elastically fixed to the second gear part 1221 of the gear member 122 by the second elastic member 135, thereby causing the fixing post 133 to abut against the second gear part 1221. The gear portion 1221 moves to the next restriction groove 1224 (ie, the second restriction groove 1224B).

Please refer to Figure 15 and Figure 16 together. Figure 15 is a partially enlarged schematic diagram of Figure 5 and Figure 16 of the action of the shearing structure of the present application. As shown in the figure, in this embodiment, the aforementioned steps of opening the shear structure 1 are repeated. Open the driving bracket 121 counterclockwise outward again. The driving bracket 121 drives the pushing member 124 to move. After one end of the pushing member 124 is separated from the second pushing groove 1223B of the second gear part 1221, one end of the pushing member 124 moves to the next pushing groove. 1223 (that is, the third pushing groove 1223C) moves in the direction. The first elastic member 125 further restricts one end of the pushing member 124 from moving against the second gear part 1221, so that one end of the pushing member 124 is fitted into the third pushing groove 1223C of the second gear part 1221. In addition, the linking portion 1211 of the driving bracket 121 again pushes the end of the restricting member 141 with the restricting post 142 away from the space between the first gear portion 1112 and the second gear portion 1221 .

Please refer to Figure 17, which is an action diagram of the shearing structure of this application. Also refer to Figure 6. As shown in the figure, in this embodiment, the driving bracket 121 is used to drive one end of the pushing member 124 to fit into the third pushing groove 1223C of the second gear part 1221 to push the third pushing groove 1223C of the gear member 122 to rotate clockwise. . At the same time, the pushing member 124 pushes the end of the limiting member 141 with the limiting column 142 through the other end of the first elastic member 125 to move toward the direction between the first gear part 1112 and the second gear part 1221 again until the limiting column 142 is clamped again. Between the first gear part 1112 and the second gear part 1221, the clockwise inward pressing action of the driving bracket 121 is stopped in this way to complete the complete shearing of the object 2 to be sheared, that is, to complete the third stage of shearing action. . At the same time, when the gear member 122 is pushed by the pushing member 124 to rotate, the fixed column 133 will break away from the second restricting groove 1224B of the second gear part 1221, and the fixed column 133 of the linking member 131 is elastically fixed by the second elastic member 135. The second gear part 1221 of the gear member 122 moves the fixing post 133 against the second gear part 1221 to the next limiting groove 1224 (ie, the third limiting groove 1224C), and the fixing post 133 is secured in the second limiting groove 1224C. The third restriction groove 1224C of the gear portion 1221.

The shearing structure 1 of this embodiment can apply force by maintaining the optimal opening angle through repeated shearing, so that branches can be easily pruned with less effort. The shearing structure of this embodiment does not limit the number of shearing segments, and the rotation angle of the gear and the shearing structure 1 can be adjusted according to the user's needs.

Please refer to Figure 18, which is a schematic diagram of the shear moment of the shear structure of the present application. As shown in the figure, in this embodiment, the first blade portion 1111 of the first blade body 111 and the second blade portion 1121 of the second blade body 112 are driven to overlap each other for shearing by applying force to the driving bracket 121. The reason why it is more labor-saving than the existing shearing structure is that the shearing structure 1 of this embodiment can provide the user with an optimal opening angle for applying force. Specifically, the external force vertically exerting force on the driving bracket 121 is the force A. The distance from the force application point of force A to the second pivot axis 123 is force application arm a. The distance from the second pivot axis 123 to the gear meshing point of the first gear part 1112 and the second gear part 1221 is the resistance arm b. The distance from the second pivot axis 123 to the first pivot axis 114 is the force applying arm c. The external force exerted vertically on the object 2 by the second blade portion 1121 of the second blade body 112 is the force B. The distance between the first pivot axis 114 and the force application point of force B is the resistance arm d. Based on the above conclusion, the force formula of this embodiment is:

Through the above formula, the force exerting effect of the shearing structure 1 through the compound lever arm force can be calculated, which is beneficial to the user in adjusting the shearing structure 1. The labor-saving factor of the multi-section shearing structure 1 of this embodiment can reach a range of 3 to 3.5 times that of traditional scissors. In addition, if the force-applying arm a and the force-applying arm c are larger than the resisting force arm b and the resisting force arm d, the magnification can be increased.

Please refer to Figures 19 and 20. Figure 19 is a schematic diagram of the adjustment component of the shearing structure of the present application, and Figure 20 is an enlarged view of area A of Figure 19. As shown in the figure, in this embodiment, the shearing structure 1 further includes an adjustment component 17. The adjustment component 17 is located on one side of the restriction component 14. The adjustment component 17 includes a rotating member 171 and a blocking member 172. One side of the rotating member 171 It has a rotating shaft 1711, and the housing 15 has a pivot hole 150. One end of the rotating shaft 1711 is passed through the pivot hole 150 and the blocking member 172, and one end of the rotating shaft 1711 is fixed to the second cutter body 112, wherein the second cutter body 112 Having a through hole 1123, the adjustment component 17 further includes a fixed shaft 175. The fixed shaft 175 is fixed in the through hole 1123, and one end of the rotating shaft 1711 is pivoted on the fixed shaft 175. One end of the rotating member 171 rotates in conjunction with the blocking member 172. One end of the rotating shaft 1711 has a non-circular connecting block 1714. The blocking member 172 has a connecting hole 1720. The connecting block 1714 of the rotating shaft 1711 is fixed to the connecting hole 1720. The blocking member 172 has a first side wall 1721 and a second side wall 1722. The distance from the first side wall 1721 to the position of the rotation axis 1711 is greater than the distance from the second side wall 1722 to the position of the rotation axis 1711. When the first side wall 1721 is against the limiting column, 142. The first side wall 1721 blocks the restriction column 142 from moving between the first gear part 1112 and the second gear part 1221. When the force is exerted on the driving bracket 121 to drive the first blade part 1111 of the first blade body 111 and the second blade part 1121 of the second blade body 112 to overlap for shearing, the first blade body 111 and the second blade body 112 are not in contact with each other.
