[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1As shown, the left rear side of the device body 1 is the welding nozzle. At this time, the rear end face of the welding nozzle grinding stone 3 is tangent to the conical surface of the welding nozzle. Note that the left end of the welding nozzle can be clamped by the chuck, thereby realizing the rotation of the welding nozzle, and the flip carrier plate 5 can be installed on the external feed screw through a thread, so that the flip carrier plate 5 can be adjusted by thread engagement to the left and right; when the welding nozzle grinding stone 3 is disassembled, the grinding stone anti-detachment column 4 is rotated by a tool to engage with the grinding stone carrier plate 2 thread, so that the grinding stone anti-detachment column 4 moves forward through the thread engagement, and the rear end of the grinding stone anti-detachment column 4 moves forward and disengages from the blind hole of the welding nozzle grinding stone 3, thereby releasing the grinding stone anti-detachment column 4 from the anti-detachment of the welding nozzle grinding stone 3, and then the welding nozzle is ground. The stone 3 can be pushed left or right out of the dovetail groove of the grinding stone carrying plate 2; when the inclination angle of the welding nozzle grinding stone 3 is adjusted, the tool is rotated forward to rotate the rotary adjusting rod 6 and the adjusting moving block 7 is threadedly engaged, so that the adjusting moving block 7 moves to the left through the threaded engagement, and the right end of the flip connecting rod 8 is driven to move synchronously to the left by the adjusting moving block 7, thereby causing the left end of the flip connecting rod 8 to flip backward, and the grinding stone carrying plate 2 is pushed to flip backward synchronously by the flip connecting rod 8, and the welding nozzle grinding stone 3 is carried by the grinding stone carrying plate 2 and flipped backward synchronously, thereby realizing the adjustment of the inclination angle of the welding nozzle grinding stone 3, and the reverse rotation of the rotary adjusting rod 6 is for the adjustment of the inclination angle of the welding nozzle grinding stone 3.

[0032] Example 2:

[0033] The difference from Example 1 is that the regular hexagonal prism of the grinding stone anti-detachment column 4 can also be set as a regular heptagonal prism, so that the grinding stone anti-detachment column 4 can only be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and disassembling the grinding stone anti-detachment column 4.

[0034] Example 3:

[0035] The difference from Example 1 is that the regular hexagonal groove of the rotation adjustment rod 6 can also be set as a regular heptagonal groove, so that the rotation adjustment rod 6 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and adjusting the rotation adjustment rod 6.
