[0028] A storage battery may be provided in the slotting machine 1, or an external wire may be used to energize the slotting machine 1, so that the slotting machine 1 can operate and be suitable for different use environments.

[0029] A plurality of water inlets 2051 are formed at the upper rear portion of the baffle 205 , and a plurality of water outlets 2052 are formed at the lower rear portion of the baffle 205 for passing water to facilitate water flow to the water absorbing sheet 207 .

[0030] The plurality of water outlets 2052 gradually decrease in size from top to bottom, so as to reduce the speed of the water flow and thus prolong the wetting time of the water absorbent sheet 207 .

[0031] The absorbent sheet 207 also includes fixing holes 2071 . Two fixing holes 2071 are opened on the absorbent sheet 207 . The fixing holes 2071 are used to fix the absorbent sheet 207 or to bond the absorbent sheet 207 to the rear side of the baffle 205 .

[0032] It also includes a bottom plate 202, a collecting groove 203, a base 301, an elastic member 302, a fixing frame 303, a fixing plate 304 and a handle 305; the bottom portion of the slotting machine 1 is provided with a bottom plate 202, and a rectangular groove is provided on the bottom plate 202 for the slotting saw blade 3 to move; the collecting groove 203 is fixedly connected to the upper surface of the bottom plate 202, and the collecting groove 203 is located at the upper outer side of the rectangular groove provided on the bottom plate 202; the base 301 is fixedly connected to the right part of the upper surface of the bottom plate 202; the elastic member 302 is rotatably connected to the base 301, and the other end of the elastic member 302 is fixedly connected to the right part of the outer side of the cover shell 201; the fixing frame 303 is fixedly connected to the left part of the upper surface of the bottom plate 202; the fixing plate 304 is slidably connected to the fixing frame 303 by bolts; the handle 305 is fixedly connected to the upper part of the fixing plate 304, and the lower end of the handle 305 is provided with a thread.

[0033] The housing of the slotting machine 1 is provided with a threaded hole 11 for connecting with the handle 305 .

[0034] When cutting grooves: connect the charging interface 2 to the external wire, or power it through the battery in the groove cutting machine 1, then install the required groove cutting saw blade 3 on the groove cutting machine 1, then manually hold the groove cutting machine 1 and control the operation of the groove cutting machine 1 to cut grooves, such as Figure 7 As shown, during the grooving process, the grooving machine 1 shields the debris generated during grooving through the cover 201, thereby preventing the debris from splashing around, thereby improving the safety of the grooving operation, and the number of grooving saw blades 3 can be increased or reduced according to the required grooving width and depth to meet the use requirements;

[0035] When the slotting machine 1 is used in firefighting, firefighters often need to use the slotting device to cut and slot buildings or objects that restrict the removal of trapped people or animals when rescuing trapped people or animals. However, the existing slotting devices are large and heavy, which is not convenient for firefighters to use. The slotting machine 1, the slotting saw blade 3 and the cover 201 can be combined into a relatively simple slotting device, and the cover 201 can be used to shield the debris generated during the slotting.

[0036] In addition, the existing grooving device generates a lot of dust during the grooving process, which is very likely to cause hidden dangers to the physical condition of the trapped persons and firefighters. In order to solve the above problems, the arc plate 204 is loaded on the front part of the cover 201 by bolts, so that the baffle 205, the pull rod 206, the water absorbent sheet 207 and the conduit 208 are all installed. Then, water or coolant is manually added to the chute inside the arc plate 204 through the conduit 208. At this time, the water will pass through the multiple water inlets 204. 051 flows to the absorbent sheet 207 and is absorbed by the absorbent sheet 207 until the entire absorbent sheet 207 is moistened, and the excess water flows out through the multiple water outlets 2052, so that the absorbent sheet 207 remains moistened. Then, the pull rod 206 is manually moved, and the movement of the pull rod 206 drives the baffle 205 to move, and the movement of the baffle 205 drives the absorbent sheet 207 to move, so that the arc plate 204 and the baffle 205 are combined with the cover shell 201 to form a semi-open protective cover, such as Figure 1 As shown, the debris generated during grooving is further shielded, thereby improving the safety protection effect for personnel;

[0037] The water-absorbing sheet 207 is located at the side of the grooving saw blade 3. When the grooving machine 1 is cutting, the grooving saw blade 3 cuts the rigid component, which is very likely to generate sparks. As the grooving saw blade 3 rotates, the sparks will fly around. At this time, the water-absorbing sheet 207 can block the flying sparks, and the water on the water-absorbing sheet 207 can quickly extinguish the sparks generated during cutting. In addition, a large amount of dust will be generated during the grooving process. The water-absorbing sheet 207 can block the dust while blocking the sparks, thereby reducing the dust from floating around.

[0038] When the slotting machine 1 has finished slotting, the pull rod 206 is manually moved, thereby causing the baffle 205 and the water-absorbing sheet 207 to move and reset;

[0039] And in the process of firefighting, when the requirement for grooving accuracy is high, the grooving machine 1 vibrates greatly during the grooving process, which makes it difficult for firefighters to hold the grooving machine 1, which easily causes the grooving machine 1 to deviate during grooving, thereby threatening the safety of trapped persons or animals. To solve the above problem, a bottom plate 202 is added to the lower part of the grooving machine 1, so that the elastic member 302 is connected to the cover 201, and the handle 305 is connected to the threaded hole 11, so that the grooving machine 1 is fixed, and then the bottom plate 202 is moved to the position where grooving is required. Then, the firefighter holds the grooving machine 1 with one hand and the handle 305 with the other hand, and moves the bottom plate 202 against the surface of the grooving position, so that the grooving machine 1 is more stable during grooving, and the grooving accuracy of the grooving machine 1 is improved.

[0040] When it is necessary to adjust the cutting angle and cutting depth of the slotting machine 1, it is only necessary to twist the bolts between the fixing frame 303 and the fixing plate 304 to adjust the position between the fixing frame 303 and the fixing plate 304, and press the handle 305 to compress the elastic member 302, so that the cutting angle and cutting depth of the slotting machine 1 can be adjusted, thereby improving the applicability of the slotting machine 1;

[0041] It should be noted that, according to the above working principle, the form of the slotting machine 1 can be switched according to the actual usage, that is, switched to Figure 1 or Figure 7 The state shown further improves the applicability of the slotting machine 1, and at the same time can collect impurities in the semi-open protective cover formed by the arc plate 204 and the baffle 205 combined with the cover shell 201 through the collecting groove 203, thereby further avoiding the problem of impurity splashing.

[0042] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
