Description

Technical Field

[0001] This utility model belongs to the technical field of forest fire prevention equipment, specifically, it relates to a portable multi-functional cutting device for quickly opening up forest firebreaks. Background Technology

[0002] In the forest fire prevention system, timely and effective establishment of forest firebreaks is a core measure for building fire prevention lines and curbing the spread of fire.

[0003] Currently, the creation of forest firebreaks mainly relies on manual logging or the use of large machinery. Manual logging primarily involves using cutting tools; however, most existing cutting tools are fixed, making them inconvenient to carry and thus reducing the need for rapid firebreak creation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the current technical problem that forest firebreak creation primarily relies on manual felling or the use of large machinery, and that manual creation mostly involves cutting tools—which are often fixed and inconvenient to carry—thus hindering the need for rapid firebreak creation, the basic concept of this invention is as follows:

[0006] A portable multi-functional cutting device for rapidly opening forest firebreaks includes a battery pack and a shoulder strap connected to the outer wall of the battery pack. The battery pack is equipped with a storage mechanism and a positioning mechanism.

[0007] The storage mechanism includes a storage shaft disposed in the battery pack, a connecting wire wound on the storage shaft, and a telescopic rod connected to the outer wall of the connecting wire. The storage shaft and the telescopic rod are designed to accommodate the length of the device, thereby improving the portability of the device.

[0008] The positioning mechanism includes a threaded sleeve with a force-bearing rod on it. A pressing plate is connected to the bottom end of the force-bearing rod, and the pressing plate is used to press the positioning telescopic rod.

[0009] In a preferred embodiment of this utility model, the storage mechanism includes a storage groove formed on the outer wall of the battery pack, a rotating groove formed on the inner wall of the storage groove, a coil spring connected to the inner wall of the rotating groove, the end of the coil spring away from the inner wall of the rotating groove being connected to the outer wall of one end of the storage shaft, one end of the connecting wire being connected to the battery pack, a cutting blade being connected to the other end of the connecting wire, a sliding sleeve being slidably provided on the outer wall of the telescopic rod, and a switch handle being connected to one side of the outer wall of the sliding sleeve.

[0010] In a preferred embodiment of this utility model, the positioning mechanism includes a threaded collar threaded to the outer wall of the threaded sleeve, the inner wall of the threaded sleeve being connected to the outer wall of the sliding sleeve, a through hole being provided on the outer wall of the threaded sleeve, a fixing ring being connected to the inner wall of the through hole, a spring being connected to the outer wall of one end of the fixing ring, a connecting ring being connected to the end of the spring away from the fixing ring, and the outer wall of the force-bearing rod being connected to the inner wall of the connecting ring.

[0011] In a preferred embodiment of this utility model, the sliding sleeve is movably sleeved on the outer wall of the connecting wire, and the inner wall of the sliding sleeve is fitted and matched with the outer wall of the telescopic rod.

[0012] In a preferred embodiment of this utility model, a handle is provided on the outer wall of the sliding sleeve.

[0013] In a preferred embodiment of this utility model, the end of the force-bearing rod away from the extrusion plate is provided with a force-bearing inclined surface, and the extrusion plate is made of rubber.

[0014] In a preferred embodiment of this utility model, the outer wall of the force-bearing rod is fitted to the inner wall of the fixing ring.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention utilizes a telescopic rod that moves along the inner wall of a sliding sleeve to extend and retract the cutting blade, thereby shortening its extension length for easy storage. Simultaneously, during retraction, a spring-loaded shaft rotates to retract and wind up the connecting wire. This combination of telescopic rod retraction and retraction completes the blade storage operation. Compared to traditional fixed cutting equipment, the ability to retract the blade reduces inconvenience caused by bushes or forest terrain during rapid movement of the carrying device.

[0017] This invention utilizes a rotating threaded collar to move along the threaded sleeve, thereby releasing the force-bearing rod from compression. The spring then rebounds, causing the force-bearing rod to return to its original position. This moves the pressing plate away from the outer wall of the telescopic rod, releasing the rod from its original position. For positioning, the threaded collar can be rotated in the opposite direction, causing it to press against the force-bearing rod. This causes the pressing plate to contact and press against the outer wall of the telescopic rod, completing the positioning process. This ensures the stability of the telescopic rod during use or storage.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, a portable multi-functional cutting device for quickly opening forest firebreaks includes a battery pack 1 and a shoulder strap 2 connected to the outer wall of the battery pack 1. The battery pack 1 is equipped with a storage mechanism 31 and a positioning mechanism 32.

[0028] The storage mechanism 31 includes a storage shaft 313 disposed in the battery pack 1. A connecting wire 314 is wound on the storage shaft 313. A telescopic rod 317 is connected to the outer wall of the connecting wire 314. The storage shaft 313 and the telescopic rod 317 are designed to accommodate the length of the device, thereby improving the portability of the device.

[0029] The positioning mechanism 32 includes a threaded sleeve 321, on which a force-bearing rod 324 is provided. A pressing plate 327 is connected to the bottom end of the force-bearing rod 324. The pressing plate 327 is used to press the positioning telescopic rod 317.

[0030] Furthermore, the storage mechanism 31 includes a storage groove 311 formed on the outer wall of the battery pack 1. A rotating groove is formed on the inner wall of the storage groove 311. A coil spring 312 is connected to the inner wall of the rotating groove. The end of the coil spring 312 away from the inner wall of the rotating groove is connected to the outer wall of one end of the storage shaft 313. One end of the connecting wire 314 is connected to the battery pack 1. A cutting blade 318 is connected to the other end of the connecting wire 314. A sliding sleeve 316 is slidably provided on the outer wall of the telescopic rod 317. A switch handle 315 is connected to one side of the outer wall of the sliding sleeve 316.

[0031] Furthermore, the sliding sleeve 316 is movably fitted onto the outer wall of the connecting wire 314, and the inner wall of the sliding sleeve 316 is properly fitted to the outer wall of the telescopic rod 317.

[0032] Furthermore, a handle 319 is provided on the outer wall of the sliding sleeve 316, which allows the operator to better hold the device for cutting operations.

[0033] The positioning mechanism 32 includes a threaded collar 322 threadedly connected to the outer wall of the threaded sleeve 321. The inner wall of the threaded sleeve 321 is connected to the outer wall of the sliding sleeve 316. A through hole is provided on the outer wall of the threaded sleeve 321. A fixing ring 323 is connected to the inner wall of the through hole. A spring 326 is connected to the outer wall of one end of the fixing ring 323. A connecting ring 325 is connected to the end of the spring 326 away from the fixing ring 323. The outer wall of the force-bearing rod 324 is connected to the inner wall of the connecting ring 325.

[0034] Furthermore, a force-bearing inclined surface is provided at the end of the force-bearing rod 324 away from the extrusion plate 327. The extrusion plate 327 is made of rubber. The force-bearing inclined surface allows the force-bearing rod 324 to be squeezed by the threaded collar 322, thereby completing the positioning operation.

[0035] Furthermore, the outer wall of the force-bearing rod 324 is fitted to the inner wall of the fixing ring 323, thereby improving the stability of the moving support of the force-bearing rod 324 in the fixing ring 323, and thus improving the positioning stability of the telescopic rod 317.

[0036] The implementation principle of a portable multi-functional cutting device for quickly clearing forest firebreaks in this embodiment is as follows: When it is necessary to quickly reach the location of the required firebreak, the battery pack 1 is first carried on the back using the shoulder strap 2. Then, the compression limit of the telescopic rod 317 is released by the positioning mechanism 32, allowing the telescopic rod 317 to move back and forth within the sliding sleeve 316, thereby driving the cutting blade 318 to extend and retract, thus reducing the overall length of the device. During the movement of the cutting blade 318 by the telescopic rod 317, the spring 312 rebounds and rotates, driving the storage shaft 313 to rebound and rotate. As the storage shaft 313 rotates, the connecting wire 314 is wound up and stored. In this way, the cutting blade 318 can be retracted and stored in conjunction with the shortening of the telescopic rod 317. Compared with traditional fixed cutting devices, because the length can be retracted, the inconvenience caused by shrubs or forest terrain is reduced when the carrying device is moved quickly.

[0037] When the unlocking and positioning mechanism 32 is engaged, the threaded collar 322 is first rotated, causing it to move along the outer wall of the threaded sleeve 321 until it disengages from the compression limit of the force rod 324. At this point, the spring 326 loses its compression and rebounds to its original position. The rebound of the spring 326 pushes the fixed ring 323 upward. As the fixed ring 323 moves upward, it drives the force rod 324 upward. This causes the force rod 324 to move the pressing plate 327 away from the outer wall of the telescopic rod 317, thus completing the release. After storage, the threaded collar 322 is rotated in the opposite direction, causing it to press against the force rod 324. This causes the pressing plate 327 to contact and press against the outer wall of the telescopic rod 317 to complete the positioning, thus ensuring the stability of the telescopic rod 317 during use or storage.
