A connecting hole 303 is penetrated between the retention grooves 301, and a plurality of drainage holes 302 are penetrated on the side of the retention groove 301 close to the No. 2 support block 4. A connecting block 305 is installed on the upper end of the front surface of the shell 1, and a connecting pipe 304 is installed inside the connecting block 305. The connecting pipe 304 is connected to the connecting hole 303, and a delivery pipe 306 is installed at the front end of the connecting pipe 304. The delivery pipe 306 is connected to the external water tank. The upper and lower ends of the connecting block 305 are respectively movably installed with a No. 1 support block 310, and one end of the No. 1 support block 310 close to the delivery pipe 306 is respectively fixedly installed with a positioning rod 314, and the positioning rod 314 is respectively installed inside the delivery pipe 306. A handle 2 is installed on the outside of the shell 1.

[0024] like Figure 4 and Figure 6As shown, in another embodiment of the present invention, both ends of the drainage hole 302 are set to be trumpet-shaped, a sealing block 307 is fixedly installed at one end of the delivery pipe 306 close to the connecting pipe 304, and the sealing block 307 is snap-fitted and installed inside the connecting pipe 304. The upper and lower ends of the connecting block 305 are respectively provided with grooves 308, and the first support block 310 is movably installed inside the groove 308. The inside of the groove 308 is respectively fixedly installed with a fixing rod 309, and the rod body of the fixing rod 309 is movably installed inside the first support block 310.

The positioning rods 314 are respectively snap-fitted and installed inside the positioning holes 313. The outer side of the support block 310 is set to be arc-shaped, and the surface of the support block 310 and the connecting block 305 overlap with each other. A positioning circular sleeve 312 is sleeved and installed between the support block 310 and the connecting block 305, and a limiting plate 311 is respectively installed on the end of the support block 310 away from the connecting block 305, and the limiting plate 311 and the positioning circular sleeve 312 are in fit.

[0025] The user inserts the delivery tube 306 into the outside of the connecting tube 304, and allows the connecting block 305 to drive the sealing block 307 to connect with the connecting block 305, so as to achieve the sealing work between the delivery tube 306 and the connecting tube 304. Then the user pulls the positioning sleeve 312 forward, and allows the positioning sleeve 312 to push the No. 1 support block 310 to rotate around the fixed rod 309 as the axis, so that the No. 1 support block 310 drives the positioning rod 314 to insert into the interior of the positioning hole 313, so as to achieve the positioning work of the delivery tube 306 and the connecting tube 304. At the same time, the No. 1 support block 310 will cooperate with the fixing rod 309 to twist the torsion spring, and then the limit plate 311 is used to position the positioning sleeve 312 to prevent the positioning sleeve 312 from falling off. Then, when the saw chain 5 is working, the liquid enters the interior of the connecting pipe 304 through the delivery pipe 306, and then the liquid entering the interior of the connecting pipe 304 enters the interior of the retention groove 301 through the connecting hole 303, and then the liquid entering the interior of the retention groove 301 can be sprayed on the surface of the saw chain 5 through the drainage hole 302 to cool down the saw chain 5;

[0026] When it is necessary to remove the delivery tube 306, the user only needs to push the positioning sleeve 312 backward to separate the positioning sleeve 312 and the No. 1 support block 310, and then the torsion spring will push the No. 1 support block 310 to reverse with the fixed rod 309 as the axis, so that the No. 1 support block 310 can be reset. At the same time, the No. 1 support block 310 will also drive the positioning rod 314 to disengage from the inside of the positioning hole 313, and then the user can take out the delivery tube 306, which is more convenient.

[0027] The working principle of a water-cooled electric saw:

[0028] When in use, the user first inserts the delivery tube 306 into the outside of the connecting tube 304, and allows the connecting block 305 to drive the sealing block 307 to connect with the connecting block 305, so as to achieve the sealing work between the delivery tube 306 and the connecting tube 304. Then the user pulls the positioning sleeve 312 forward, and allows the positioning sleeve 312 to push the No. 1 support block 310 to rotate around the fixed rod 309 as the axis, so that the No. 1 support block 310 drives the positioning rod 314 to insert into the interior of the positioning hole 313, so as to achieve the positioning of the delivery tube 306 and the connecting tube 304. The saw chain 5 works in the same position, and the No. 1 support block 310 cooperates with the fixing rod 309 to twist the torsion spring, and then the limit plate 311 is used to position the positioning sleeve 312 to prevent the positioning sleeve 312 from falling off. Then, when the saw chain 5 is working, the liquid enters the interior of the connecting pipe 304 through the delivery pipe 306, and then the liquid entering the connecting pipe 304 enters the interior of the retention groove 301 through the connecting hole 303, and then the liquid entering the interior of the retention groove 301 can be sprayed on the surface of the saw chain 5 through the drainage hole 302 to cool it down.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
