[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] See also Figures 1 to 6 A chain saw for rock cutting provided by an embodiment of the utility model comprises: a chain saw body 1, one side of the chain saw body 1 is fixedly connected to a handrail 4, one end of the chain saw body 1 is installed with a power device 5, both ends of the chain saw body 1 are provided with adjustment devices 2, and one side of the chain saw body 1 close to the handrail 4 is provided with an auxiliary device 3.

[0035] In the embodiments of the present invention, please refer to Figures 2 to 4The adjusting device 2 includes a plurality of connecting blocks 201, and the plurality of connecting blocks 201 are fixedly connected to the chain saw body 1. An adjusting groove 202 is provided at one end of the connecting block 201 away from the side of the chain saw body 1. The inner wall of the adjusting groove 202 is fixedly connected with a same fixing rod 203 on both sides. The circular arc surface of the fixing rod 203 is rotatably connected with a clamp 204. The inner wall thread of the clamp 204 is penetrated by a screw rod 205. The screw rod 205 is threadedly connected to the inner wall of the connecting block 201. The plurality of clamps 204 are movably connected with a same water pipe 206 on one side close to the chain saw body 1. A plurality of water spray ports 207 are provided at both ends of the circular arc surface of the water pipe 206. The plurality of water spray ports 207 are evenly distributed on the water pipe 206. The chain saw body 1 can be used to cut rocks on the arc surface. However, when cutting rocks, it is found that when the chain saw body 1 cuts rocks for a long time, the surface of the chain saw body 1 will cause heat, which will affect the service life of the chain saw body 1. The dust generated by using the chain saw body 1 to cut rocks will also affect the respiratory tract of workers using the chain saw body 1, causing respiratory diseases in the workers. At this time, the workers can use the adjustment device 2 to cool the contact position between the chain saw body 1 and the rock, and can also remove the dust generated by the chain saw body 1 when cutting rocks. While increasing the service life of the chain saw body 1, it can also improve the protection effect of the respiratory tract of workers when using it.The two ends of the arc surface of the fixing rod 203 are slidably connected with coil springs 208, and the two ends of the coil spring 208 are fixedly connected to the clamp 204 and the connecting block 201 respectively. When the clamp 204 is opened and the water pipe 206 is placed between the clamp 204 and the connecting block 201, the coil spring 208 will drive the clamp 204 to move in the direction of the water pipe 206, so that the speed of fixing the water pipe 206 through the clamp 204 can be increased under the drive of the coil spring 208, and the clamp 204 is close to the water pipe 206. 06, there are a plurality of anti-skid grooves 209, which are evenly distributed on one side of the clamp 204. When the clamp 204 is used to connect with the water pipe 206, the anti-skid grooves 209 on the water pipe 206 can increase the friction between the water pipe 206 and the clamp 204, thereby improving the stability of the clamp 204 and the water pipe 206 when they are in contact. A guide block 210 is fixedly connected to one end of the screw rod 205 close to the chain saw body 1, and the cross section of the guide block 210 is arc-shaped. When the screw rod 205 is connected to the inner wall of the clamp 204, the guide block 210 installed on the screw rod 205 can reduce the angle required for the connection between the screw rod 205 and the clamp 204, thereby increasing the speed of the connection between the inner wall of the clamp 204 and the screw rod 205 by reducing the required connection angle. A connecting ring 211 is fixedly connected to the side of the clamp 204 away from the chain saw body 1. The cross-section of the connecting ring 211 is circular. When the screw rod 205 drives the clamp 204 to connect with the connecting block 201, the connecting ring 211 installed on the clamp 204 can avoid the occurrence of extrusion damage when the screw rod 205 and the clamp 204 come into contact. The connecting ring 211 can protect the connection between the clamp 204 and the connecting block 201. The fixed rod 203 is a titanium alloy rod. The surface of the rod body of the fixed rod 203 made of titanium alloy is relatively hard, which also makes it difficult for the surface of the rod body of the fixed rod 203 made of titanium alloy to deform under long-term use, and has a good service life.

[0036] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary device 3 includes two arc blocks 31, and the two arc blocks 31 are slidably connected to the handrail 4. A contact plate 32 is fixedly connected to the side of the arc block 31 away from the handrail 4. Two connecting blocks 33 are fixedly connected to the sides of the arc block 31 close to the contact plate 32. Every two connecting blocks 33 form a group, and the inner wall thread of each group of connecting blocks 33 is penetrated by the same screw 34. When a worker uses the chain saw body 1 to cut rocks for a long time through the handrail 4, it is found that the worker's hands sweat and cannot hold the handrail 4 tightly, resulting in the chain saw body 1 being loose. The body 1 of the chain saw may slip from the hand, and the slipped chain saw body 1 poses a great safety risk to the worker. The auxiliary device 3 can be used to increase the friction between the hand and the armrest 4 to prevent the hand from sweating and being unable to grip the armrest 4. Both ends of the sides of the two arc blocks 31 close to each other are fixedly connected with connecting pads 35. When the two arc blocks 31 contact each other, the connecting pads 35 installed on the arc blocks 31 can prevent the two arc blocks 31 from being damaged when they contact each other. The connecting pads 35 can effectively prevent the two arc blocks 31 from being damaged by contact.

[0037] The working principle of a rock cutting chain saw provided by the utility model is as follows: when using the chain saw body 1 to cut rocks, fill the water bucket with water, connect the water pipe 206 to the water outlet of the water pump, and then place the water inlet of the water pump in the water bucket, first open the clamp 204, the clamp 204 will rotate on the arc surface of the fixed rod 203, and then place the tube body of the water pipe 206 between the clamp 204 and the connecting block 201, and then press the clamp 204 toward the inner wall of the connecting block 201 to overlap the inner wall of the clamp 204 with the inner wall of the connecting block 201, and then close the inner wall of the clamp 204. The screw rod 205 is rotated between the inner wall of the clamping opening 204 and the inner wall of the connecting block 201, so that the screw rod 205 can rotate between the inner wall of the clamping opening 204 and the connecting block 201, and the water pipe 206 can be fixed between the clamping opening 204 and the connecting block 201. At this time, the water pump is started, and because a water spraying port 207 is opened on the water pipe 206, the water pump will spray the water in the bucket through the water spraying port 207 on the water pipe 206, so that the chain saw body 1 can be cooled when it is working, and the dust generated when the chain saw body 1 is working can also be removed. When the clamping opening 204 is opened and the water pipe 206 is placed between the clamping opening 204 and the connecting block 201, the coil spring 2 08 will drive the clamp 204 to move in the direction of the water pipe 206, so that the speed of fixing the water pipe 206 through the clamp 204 can be increased under the drive of the coil spring 208. When the clamp 204 is connected to the water pipe 206, the anti-slip groove 209 on the water pipe 206 can increase the friction between the water pipe 206 and the clamp 204, so as to improve the stability of the clamp 204 and the water pipe 206 when they are in contact. When the screw rod 205 is connected to the inner wall of the clamp 204, the guide block 210 installed on the screw rod 205 can reduce the angle required for the connection between the screw rod 205 and the clamp 204, thereby The speed of connection between the inner wall of the clamp 204 and the screw rod 205 can be increased by reducing the required connection angle. When the screw rod 205 drives the clamp 204 to connect with the connecting block 201, the connecting ring 211 installed on the clamp 204 can avoid extrusion damage when the screw rod 205 and the clamp 204 come into contact. The connecting ring 211 can protect the connection between the clamp 204 and the connecting block 201. The surface of the fixing rod 203 made of titanium alloy is relatively hard, which also makes it difficult for the surface of the fixing rod 203 made of titanium alloy to deform after long-term use, and has a better service life.

[0038] When the friction between the armrest 4 and the hand needs to be increased, the two arc blocks 31 are placed on the arc surface of the armrest 4, and then the two connecting blocks 33 are connected by a screw 34 through a connecting block 33. After the screw 34 is connected to the connecting block 33, the arc block 31 can be fixed on the armrest 4. The contact plate 32 installed on the arc block 31 can increase the friction between the worker's hand and the armrest 4, and improve the stability of the worker in taking the chain saw body 1 through the armrest 4. When the two arc blocks 31 contact each other, the connecting pad 35 installed on the arc block 31 can prevent the two arc blocks 31 from being damaged when they contact each other. The connecting pad 35 can effectively prevent the two arc blocks 31 from being damaged by contact.
