[0025] The embodiments of the present utility model are described in detail below. In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0026] Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The terminology used herein is intended to explain the embodiments and is not intended to limit and / or restrict the present invention.

[0028] Example 1

[0029] like Figures 1-6 As shown, the extension mounting structure of the power tool in this embodiment is used to install it onto the tool body 10. The tool body 10 is a conventional hand scissor main unit structure in the field, consisting of a housing, a blade box, and a blade body. One side of the housing has a power terminal 11, which is a plug-in structure for inserting a battery pack for power supply. At the same time, a boss 12 structure is formed on the other side of the housing near the upper end. The boss 12 structure extends outward and forms an angle with the housing.

[0030] Specifically, the extended installation structure includes an installation module 20 that is detachably connected to the tool body 10, a spring-loaded module 30 disposed within the installation module 20, a fixing module 40 connected to the spring-loaded module 30, and a pressing module 50 disposed on the installation module 20. Through the cooperation of the spring-loaded module 30 and the fixing module 40, the installation module 20 can be stably connected to the tool body 10.

[0031] The installation module 20 is the main body of the extended installation structure and can be a shell-shaped structure. A plug-in end 21 is provided on one side of the installation module 20. The plug-in end 21 is plugged into the power connection end 11. A battery pack can also be inserted outside the plug-in end 21 for use. Thus, the installation module 20 can be adapted to different models and formats of power supplies. A second connection unit 22 is provided inside the installation module 20. A second support unit 23 is provided on one side of the second connection unit 22. An opening 24 is provided at the upper end of the installation module 20. Guide plates 25 extending inward are provided on both sides of the opening 24. During installation, the plug-in end 21 is connected to the power connection end 11 to achieve connection with the tool body 10. The installation module 20 is generally semi-open, surrounding the left or right side, top, and rear side of the tool body 10.

[0032] The spring-loaded module 30 provides elastic force and includes an elastic body 31. One end of the elastic body 31 has a limiting member 32 extending from it, and the other end has a connecting member 33 extending from it. The spring-loaded module 30 can adopt a conventional torsion spring structure. The limiting member 32 and the connecting member 33 are extended protrusions at both ends of the torsion spring. A groove is provided in the second support unit 23 for the limiting member 32 to be inserted, allowing the limiting member 32 to abut against the second support unit 23.

[0033] Additionally, the fixing module 40 abuts against the boss 12 under the action of the springback module 30. The fixing module 40 includes a first connecting unit 41. A first force-bearing unit 42 and a first support unit 43 are respectively provided on both sides of the first connecting unit 41. The first support unit 43 is movably abutted against the boss 12. The first connecting unit 41 is a shaft-shaped structure, the first force-bearing unit 42 is a straight plate-shaped structure, and the first support unit 43 is a folded plate-shaped structure. Its end is folded upward and abuts against the angle formed by the boss 12 and the tool body 10. The first connecting unit 41 and the second connecting unit 22 are inserted and matched, that is, the second connecting unit 22 is a matching tubular structure.

[0034] Furthermore, the elastic body 31 is sleeved on the first connecting unit 41, and the adapter 33 is connected to the fixing module 40. Specifically, a hole can be opened on the first support unit 43 for the adapter 33 to pass through and be fixed.

[0035] Furthermore, under the action of external force, the pressing module 50 can drive the fixing module 40 to detach from the boss 12 and drive the pushing tool body 10 away from the installation module 20. The pressing module 50 includes a pressing base 51, and contact body 1 52 and contact body 2 53 are respectively extended on both sides of the pressing base 51. The position of contact body 1 52 corresponds to the position of the first force-bearing unit 42, and the position of contact body 2 53 corresponds to the position of the boss 12. Here, the first support unit 43 is located on one side of the boss 12, and contact body 2 53 is located on the other side of the boss 12.

[0036] The pressing base 51 is generally U-shaped, the first contact body 52 is a folded plate structure, extending obliquely downward to the outside of one end of the pressing base 51, and can abut against the upper end of the first force-bearing unit 42. The second contact body 53 extends directly along the other end of the pressing base 51 and can abut against the upper end of the boss 12.

[0037] The pressing module 50 is inserted into the opening and partially protrudes to the outside of the mounting module 20. The guide plate 25 contacts and cooperates with the outer side of the pressing base 51 to guide the movement direction of the pressing module 50.

[0038] When disassembling this utility model, a downward force is applied to the pressing module 50, and the first contact body 52 abuts against the first force-bearing unit 42, causing it to rotate counterclockwise against the elastic force until the first support unit 43 in the fixed module 40 is pushed open and disengaged from the boss 12. The pressing module 50 is then pressed, and the second contact body 53 abuts against the boss 12, causing the tool body 10 to detach from the installation module 20, thus achieving unlocking and disassembly.

[0039] The examples, embodiments, and special forms of this utility model have been shown and described in detail in the accompanying drawings and foregoing description, and should also be considered illustrative rather than restrictive. The description of a particular feature in one embodiment does not imply that those particular features must be limited to that one embodiment. Features of one embodiment can be used in combination with features of other embodiments, as will be understood by those skilled in the art, whether explicitly stated or not. Exemplary embodiments have been shown and described, and all variations and modifications fall within the spirit of this utility model and are intended to be protected.
