[0019] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] like Figures 1-5 As shown, a multi-functional hammer for interior decoration includes a hammer head 1 and a cutting mechanism disposed inside the hammer head 1. The cutting mechanism inside the hammer head 1 can cut cables after insertion. Combining the cutting mechanism with the hammer head 1 facilitates handling different usage needs. The cutting mechanism includes a cutting blade 16, a lower pressure chamber 14 slidably disposed on the lower half of the cutting blade 16, and a return spring 15 for the lower pressure chamber 14 to return to its original position. A cutting groove 2 is formed in the middle of the hammer head 1. The upper half of the cutting blade 16 is located inside the cutting groove 2. The middle part of the cutting blade 16 is rotatably connected to the inner wall of the hammer head 1. An extension rod 3 is fixedly disposed at the lower end of the hammer head 1. The lower pressure chamber 14 is slidably disposed inside the extension rod 3. When the operator pulls the lower pressure chamber 14, the lower pressure chamber 14 slides towards the lower half of the cutting scissors 16, thereby allowing the upper half of the cutting scissors 16 to move in opposite directions, so that the cutting scissors 16 can cut the wire harness. At the same time, the reset spring 15 allows the lower pressure chamber 14 to rebound and reset without the action of external force, thereby allowing the upper half of the cutting scissors 16 to move in opposite directions, so as to facilitate the next cutting work. Meanwhile, the rotating part in the middle of the cutting scissors 16 is rotatably connected to the inner wall of the hammer head 1. This not only restricts the position of the cutting scissors 16, but also does not affect the normal use of the cutting scissors 16.

[0021] The lifting mechanism includes two ejector springs 9 for pushing the extension rod 3, several anti-slip blocks 10 fixedly disposed on one side of the extension rod 3, and a pull plate 5 for limiting the lifting of the extension rod 3. One side of the pull plate 5 is slidably connected to the anti-slip blocks 10 via several anti-slip grooves 501. A base rod 4 is fixedly connected to one side of the pull plate 5 via four elastic telescopic rods 7. The extension rod 3 is slidably disposed inside the base rod 4. Both ends of the ejector springs 9 are fixedly connected to the base rod 4 and the extension rod 3, respectively. The extension rod 3 and the base rod 4 are connected by the ejector springs 9, thereby allowing the extension rod 3 to be pushed outwards from the base rod 4 by the upward movement of the ejector springs 9. This allows the extension rod 3 to be raised in height. At the same time, the stop block 10 fixed on one side of the extension rod 3 can be limited by the pull plate 5. Thus, when the pull plate 5 moves outward, the extension rod 3 moves upward under the action of the push-out spring 9. Conversely, when the pull plate 5 returns to its original position, it can slide and connect with the stop block 10 through the anti-slip groove 501, thereby limiting and fixing the extension rod 3. This limits the extension height of the extension rod 3. At the same time, the pull plate 5 can be fixedly connected to the bottom rod 4 through the elastic telescopic rod 7, so that the pull plate 5 can rebound and return to its original position through the spring inside the elastic telescopic rod 7. The elastic telescopic rod 7 also serves as a guide for the extension and contraction of the spring.

[0022] Furthermore, such as Figure 2As shown, a slide rail groove 8 is provided on one side of the base rod 4, and a pull plate 5 is located on one side of the slide rail groove 8. A finger ring 6 is fixedly provided on both the pull plate 5 and one side of the base rod 4. The slide rail groove 8 can prevent the movement of the stop block 10 from being affected, so that it can be raised and lowered inside the base rod 4. The finger ring 6 allows the user's fingers to be inserted, which not only increases the connection between the hand and the base rod 4, but also allows the extension rod 3 to be raised and lowered simply by opening and closing the palm.

[0023] Furthermore, such as Figure 4 and Figure 5 As shown, lower stop blocks 18 are fixedly installed on both sides of the lower pressure chamber 14. The lower stop blocks 18 are fixedly connected to the upper stop blocks 17 through the return spring 15. The upper stop blocks 17 are fixedly connected to the inner wall of the extension rod 3. The position of the return spring 15 can be fixed by the upper stop blocks 17 and the lower stop blocks 18. The return spring 15 is slidably provided with a telescopic guide rod 19. Both ends of the telescopic guide rod 19 are fixedly connected to the upper stop blocks 17 and the lower stop blocks 18 respectively. The telescopic guide rod 19 is used to guide the return spring 15. The setting of the telescopic guide rod 19 can guide the trajectory of the return spring 15's extension and rebound, thereby preventing the lower pressure chamber 14 from tilting when moving.

[0024] Furthermore, such as Figures 2-5 As shown, a pull rod 13 is fixedly installed on one side of the pressure chamber 14. The end of the pull rod 13 away from the pressure chamber 14 extends to the outside and is rotatably connected to a pull ring. The user can pull the pull ring to make the pull rod 13 pull the pressure chamber 14, thereby allowing the pressure chamber 14 to descend. A slide groove 11 is opened on one side of the extension rod 3. The slide groove 11 is used to guide the sliding of the pull rod 13. A dustproof pad 12 is fixedly installed inside the slide groove 11. By opening the slide groove 11 on one side of the extension rod 3, the extension rod 3 can slide in a predetermined track. At the same time, the dustproof pad 12 is made of soft material to prevent dust from entering the interior of the extension rod 3 through the slide groove 11. The middle of the dustproof pad 12 has a joint for the movement of the pull rod 13.

[0025] Furthermore, such as Figure 1 As shown, caps 201 are respectively attached to both sides of the cutting groove 2. Each cap 201 has a cap groove of different diameter. The opening of the cutting groove 2 can be closed by the caps 201 through the snap-fit ​​connection. At the same time, the cap groove on one side of the cap 201 can be used to tighten the same nut.

[0026] In this embodiment, as Figures 1-5 As shown in this embodiment, the principle of a multi-functional hammer for interior decoration is as follows: When the lower pressure chamber 14 is pulled, it slides towards the lower half of the cutting blade 16, allowing the upper half of the cutting blade 16 to move in opposite directions. This enables the cutting blade 16 to cut the wire harness. Simultaneously, the return spring 15 allows the lower pressure chamber 14 to spring back and return to its original position without external force, causing the upper half of the cutting blade 16 to move in opposite directions for the next cutting operation. Furthermore, the rotating part in the middle of the cutting blade 16 is rotatably connected to the inner wall of the hammer head 1. This not only restricts the position of the cutting blade 16 but also does not affect its normal use.
