It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0045] Embodiment 1:

[0046] like Figure 1-Figure 6 As shown, the utility model discloses a packaging box for conveniently replacing tool heads, comprising:

[0047] The box body 1 is square in shape as a whole, and a box cavity 11 with an open upper end is provided in the box body 1, and an assembly opening 111 is provided at the front side of the box cavity 11. In addition, an assembly position 2 is provided in the box cavity 11;

[0048] A box cover 3, which is disposed on the box body 1 to open or close the box cavity 11;

[0049] Among them, the tool head 5 (pliers head) to be packaged is placed in the assembly position 2 for packaging, and the assembly end of the tool head 5 placed in the assembly position 2 faces the assembly opening 111, and the handle 6 extends from the assembly opening 111 into the box cavity 11 so that the assembly end of the handle 6 and the assembly end of the tool head 5 placed in the assembly position 2 match.

[0050] When the tool head 5 needs to be assembled on the handle 6, the box cover 3 is first operated to open the box cavity 11 so that the assembly opening 111 is in an open state, and then the handle 6 is inserted into the box cavity 11 through the assembly opening 111. The assembly end at the rear end of the handle 6 and the assembly end at the front end of the tool head 5 are assembled with each other through alignment. Finally, the tool head 5 is removed from the assembly position 2 by operating the handle 6 to obtain an assembled tool. The assembly can be completed with only one hand, making the operation more convenient. In addition, there is no need to touch the tool head 5 during the assembly process to prevent the structure of the tip on the tool head 5 and the tool head 5 with a spring from automatically opening and causing scratches and other dangerous situations. 2. When the tool head 5 needs to be disassembled, the tool head 5 is first placed in the assembly position 2, and at this time the handle 6 is inserted into the assembly opening 111. Then, the handle 6 is pulled forward to separate the handle 6 and the tool head 5, making disassembly convenient and operation safe.

[0051] The assembly position 2 in this embodiment is provided with a disassembly opening 21 at one end thereof facing the assembly opening 111 , and the disassembly opening 21 is used for the tool head 5 to be inserted into or removed from the assembly position 2 .

[0052] Therefore, the assembly position 2 limits the up and down, left and right, and rear sides of the tool head 5, so that during the mating connection process of the handle 6 and the tool head 5, the handle 6 exerts a force from front to back on the tool head 5, and this force is effectively limited by the assembly position 2 to prevent the tool head 5 from popping out of the assembly position 2 during the mating force process and causing danger.

[0053] Preferably, the upper end of the assembly position 2 in this embodiment is open, so that the tool head 5 in the assembly position 2 can be easily observed through the opening, which is convenient for confirming and selecting the tool head 5. In addition, a limiting portion 22 is integrally formed at the upper end of the assembly position 2, so that the limiting portion 22 limits the tool head 5 at the upper end of the tool head 5 to prevent the tool head 5 from escaping upward from the assembly position 2.

[0054] In addition, an anti-slip component 23 is provided on the assembly position 2 in the present embodiment, and the anti-slip component 23 is arched from both sides to the middle; so that the tool head 5 is guided into the assembly position 2 through the outer peripheral surface of the anti-slip component 23 during the process of being inserted into the assembly position 2 under force, and the tool head 5 is guided out of the assembly position 2 through the outer peripheral surface of the anti-slip component 23 during the process of being forced out of the assembly position 2. In addition, in a non-stressed state, the tool head 5 located in the assembly position 2 is restricted by the anti-slip component 23 and cannot be out of the assembly position 2, thereby ensuring the built-in stability of the tool head 5.

[0055] The outer peripheral surface of the anti-slip member 23 may be an inclined surface or an arc surface to ensure the guiding effect.

[0056] Preferably, the shape of the assembly position 2 in this embodiment is adapted to the shape of the tool head 5 adapted to the assembly position 2 in the closed state.

[0057] Therefore, the tool head 5 can only be placed in the assembly position 2 in the closed state. 1. Foreign objects, fingers, etc. cannot be inserted into the tool head 5 to ensure the safety of the packaging. 2. The tool head 5 equipped with a spring can be stretched outward and more stably pressed against the surrounding wall of the assembly position 2 through the restoring force of the spring. 3. The space occupied by the tool head 5 in the closed state is minimized, so the overall volume of the packaging box is smaller.

[0058] In other embodiments, the shape of the assembly position 2 is adapted to the shape of the tool head 5 adapted to the assembly position 2 in a fully or partially opened state.

[0059] It should be noted that in the closed state, the two clamping parts at the front end of the tool head 5 are close to each other, while in contrast, the tool head 5 has an open state, and the two clamping parts at the front end of the tool head 5 are far away from each other.

[0060] Among them, the box cavity 11 in this embodiment includes a head area 112 and a handle area 113, the assembly opening 111 is arranged on the front side of the head area 112, and the handle area 113 is arranged on the rear side of the head area 112; wherein, the assembly position 2 is arranged in the head area 112, the number of the assembly positions 2 is multiple, and each assembly position 2 is arranged in the left-right direction; wherein, the length direction of the handle area 113 is arranged in the left-right direction, and the handle area 113 is for the handle 6 to be placed.

[0061] Therefore, 1. the packaging box can be used to package the handle 6 and multiple tool heads 5, and when the handle 6 and a specific tool head 5 need to be assembled, the handle 6 is first taken out from the handle area 113, and then inserted into the box cavity 11 from the front side of the box body 1 through the assembly opening 111, so that it can be assembled in alignment with the tool head 5 on the specific assembly position 2; 2. the head area 112 formed by the assembly positions 2 arranged on the left and right and the handle area 113 extending on the left and right are adapted in shape to make the overall structure more compact and the overall volume of the packaging box smaller.

[0062] The tool heads 5 packaged between different assembly positions 2 may be of the same model or different models, and the specific packaging combination is set according to actual conditions.

[0063] Specifically, there are 5 assembly positions 2 in this embodiment, which are, from left to right, assembly position 2 for adapting to conventional scissor heads, assembly position 2 for adapting to fruit branch shear heads, assembly position 2 for adapting to crimping chucks, assembly position 2 for adapting to wire stripping heads, and assembly position 2 for adapting to diagonal pliers heads.

[0068] Among them, in this embodiment, a detachable mounting part 4 is provided in the box body 1, and the assembly position 2 is set on the mounting part 4, so that when the box body 1 is not replaced, different packaging boxes can be formed by replacing the mounting part 4 with assembly positions 2 of different numbers, layouts and shapes, so that there are more types of packaging boxes.

[0069] Among them, the box body 1 in this embodiment is provided with four upwardly extending cylinders in the box cavity 11, and a cylindrical connecting hole 12 is formed in each cylinder. Correspondingly, four downwardly extending connecting posts 41 are provided on the mounting member 4, so that the connecting posts 41 and the connecting holes 12 are plugged into and matched with each other, so that the mounting member 4 is installed on the box body 1.

[0070] Specifically, each connecting pin 41 includes four spacers 411 arranged at intervals along the circumferential direction and a deformation cavity 412 located between the spacers 411; in addition, a limiting convex ring 13 is provided on the inner peripheral wall of the upper end of each connecting socket 12, and the outer peripheral surface of the convex ring is arc-shaped. Correspondingly, a limiting convex portion 42 is provided on the outer side of each spacer 411, and each limiting convex portion 42 is combined to form a ring interrupted by the deformation cavity 412 in the middle. Therefore, in the process of inserting the spacer 411 into the connecting socket 12, the limiting convex portion 42 is deformed as the spacer 411 under the action of the deformation cavity 412 and passes over the limiting convex ring 13 more smoothly to realize the connection of the connecting pin 41 to the connecting socket 12, and the limiting convex portion 42 and the limiting convex ring 13 are restrained from each other up and down to limit the connection pin 41 from slipping out of the connecting socket 12, thereby ensuring the stability of the installation of the mounting member 4 and the box body 1.

[0071] In addition, the box cover 3 in this embodiment includes an upper cover portion 31 and a side cover portion 32; the upper cover portion 31 is used to cover the box body 1 to seal the box cavity 11; the side cover portion 32 is used to cover the horizontal side of the box body 1 to seal the assembly opening 111.

[0072] Specifically, a first hinge portion 311 is provided on the rear side of the upper cover portion 31, and a second hinge portion 14 is provided on the rear side of the box body 1. The first hinge portion 311 and the second hinge portion 14 cooperate to enable the box cover 3 to be flipped and set on the box body 1; and a mounting hook 321 is provided at the lower end of the side cover portion 32, and a matching portion 15 is provided on the box body 1. In the process of the box cover 3 flipping forward to close the box cavity 11, the mounting hook 321 passes over the matching portion 15 and is hooked with the matching portion 15 to limit the flipping of the box cover 3 relative to the box body 1, thereby ensuring the stability of the closing of the box cavity 11.

[0073] In other embodiments, the box cover 3 and the box body 1 are connected at the left and right sides by means of buckles, so that the box cover 3 and the box body 1 can be disassembled when the buckle connection is released.
