[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides one embodiment: a novel vehicle-mounted portable multi-functional manual demolition tool, comprising a housing 1, a hexagonal rod 3 rotatably connected to the left rear end of the housing 1, a gear 4 fixedly connected to the right end of the hexagonal rod 3, the hexagonal rod 3 driving the gear 4 to rotate, a ratchet 5 fixedly connected to the right end of the gear 4, a spring 7 fixedly connected to the right rear end of the inner wall of the housing 1, a ratchet 6 fixedly connected to the left side of the spring 7, the ratchet 6 and ratchet 5 meshing together, the spring 7 pushing the ratchet 6 to mesh and fix with the ratchet 5, and a push rod 8 slidably connected to the middle of the front end of the housing 1, the lower rear end of the push rod 8 meshing with the top of the gear 4. Next, the front end of the push rod 8 is rotatably connected to the left and right sides of the connecting parts 9, and the bottom of the front end of the two connecting parts 9 is rotatably connected to the pliers 10. The push rod 8 drives the pliers 10 to open and close through the connecting parts 9. An adjustable lever mechanism 2 is installed on the outside of the hexagonal rod 3. The adjustable lever mechanism 2 is used to rotate the hexagonal rod 3. The front and rear sides of the outer wall of the outer shell 1 are both equipped with handles 11. The left and right sides of the two handles 11 are threaded with screws 12. Screws 12 are used to install the handles 11. The middle right side of the ratchet 2 6 is fixedly connected to the pull rod 13. The right end of the pull rod 13 is fixedly connected to the limit block 14. The limit block 14 is used to limit the position of the pull rod 13.

[0032] Specifically, the rotation of the hexagonal lever 3 drives the rotation of the gear 4. When the gear 4 rotates, it drives the push rod 8 to move back and forth in a meshing manner, thereby driving the two connecting parts 9 to pull the corresponding pliers 10 to open and close to complete the demolition. When the push rod 8 is pushed forward, the ratchet 2 6 is pushed outward by the ratchet 1 5, and then pushed back by the spring 7 to mesh with the ratchet 1 5 and fix it. The handle 11, which is fixed by the screw 12, facilitates the transport of the new vehicle-mounted portable multi-functional manual demolition tool. The pull rod 13 is used to pull the ratchet 2 6, and the limit block 14 is used to limit the position of the pull rod 13.

[0033] Reference Figure 5The adjustable lever mechanism 2 includes a hexagonal wrench 201. The inner side of the hexagonal wrench 201 is slidably connected to the left side of the outer wall of the hexagonal rod 3. A rotating rod 202 is fixedly connected to the top of the hexagonal wrench 201. The rotating rod 202 rotates the hexagonal rod 3 through the hexagonal wrench 201. A sliding groove 203 is provided on the rear side of the inner wall of the rotating rod 202. Multiple fixing grooves 204 are provided at equal intervals on the right side of the inner wall of the rotating rod 202. An extension rod 205 is slidably connected to the inner side of the rotating rod 202. The extension rod 205 slides inside the rotating rod 202. A fixing buckle 206 is fixedly connected to the bottom of the outer wall of the extension rod 205. The extension rod 205 is fixed in height by the fixing buckle 206 and the fixing groove 204. A rubber sleeve 15 is fixedly connected to the top of the outer wall of the extension rod 205. The outer wall of the rubber sleeve 15 is provided with anti-slip texture 16. The anti-slip texture 16 is used to improve the anti-slip performance of the rubber sleeve 15.

[0034] Specifically, the extension rod 205 fixed inside the rotating rod 202 is rotated so that the fixing buckle 206 fixed under the extension rod 205 slides from the fixing groove 204 into the slide groove 203. Then, the extension rod 205 is pulled upward to a suitable length. Then, the extension rod 205 is reversed so that the fixing buckle 206 fixed under the extension rod 205 slides into the corresponding fixing groove 204 to fix its length. Then, the hexagonal wrench 201 fixed under the rotating rod 202 is put on the hexagonal rod 3 and twisted. The rubber sleeve 15 fixed outside the extension rod 205 improves its grip by the anti-slip texture 16 opened on its outside.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A pull ring 17 is fixedly connected to the right side of the limiting block 14. An anti-slip sleeve 18 is fixedly connected to the outer wall of the pull ring 17. The anti-slip sleeve 18 is used to improve the anti-slip performance of the pull ring 17. A bearing 19 is fixedly connected to the middle of the outer wall of the hexagonal rod 3. A light 20 is fixedly connected to the bottom front side of the outer shell 1. The bearing 19 and the light 20 are used to assist the new vehicle-mounted portable multi-functional manual demolition tool in operation. Screws 21 are threadedly connected to the front and rear ends of the right side of the outer shell 1. Fixing clips 22 are threadedly connected to the outer walls of the two screws 21. Screws 21 are used to install fixing clips 22.

[0036] Specifically, the anti-slip sleeve 18 fixed to the outside of the pull ring 17 can improve its anti-slip properties, the bearing 19 can make the rotation of the hexagonal rod 3 smoother, the lighting lamp 20 can provide lighting when the new vehicle-mounted portable multi-functional manual demolition tool is working, and the fixing clip 22 installed by screw 21 can fix the adjustable lever mechanism 2 when not in use.

[0037] Working principle: When using the new type of vehicle-mounted portable multi-functional manual demolition tool for demolition work, firstly rotate the hexagonal rod 3. The rotation of the hexagonal rod 3 drives the rotation of the gear 4. When the gear 4 rotates, it will drive the push rod 8 to move back and forth in a meshing manner. This will drive the two connecting parts 9 to pull the corresponding pliers 10 to open and close to complete the demolition. When the push rod 8 is pushed forward, the ratchet 2 6 will be pushed outward by the ratchet 1 5. Then it will be pushed back by the spring 7 and mesh with the ratchet 1 5 to fix it. This achieves the effect of preventing rotation during demolition.

[0038] When encountering obstacles with significant resistance during demolition using the new vehicle-mounted portable multi-functional manual demolition tool, first rotate the extension rod 205 fixed inside the rotating rod 202, causing the fixing buckle 206 fixed under the extension rod 205 to slide from the fixing groove 204 into the slide groove 203. Then, pull the extension rod 205 upwards to a suitable length, and then reverse the extension rod 205 to allow the fixing buckle 206 fixed under the extension rod 205 to slide into the corresponding fixing groove 204 to fix its length. Then, put the hexagonal wrench 201 fixed under the rotating rod 202 onto the hexagonal rod 3 and twist it, thereby achieving the effect of extending the adjustable lever mechanism 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
