[0022] The spray head 14 is moved out of the cooling water tank 13, and cooperates with the extrusion of the sealing slide plate 7 to cool the surface of the grinding wheel 2. The telescopic chamber 5 moves outward, so that the telescopic chamber 5 can protect the part where the staff observes the grinding situation and prevent direct viewing of the grinding area. While protecting the eyes, it also prevents some debris from splashing. Cooperating with the extrusion of the coolant, the practicability of the grinder is greatly increased.

[0023] In an optional embodiment: the connection shell 3 and the protection box 4 are magnetically connected, and a strong magnet is provided on a side wall of the protection box 4 close to the connection shell 3.

[0024] It should be noted that the relative position and angle between the connecting shell 3 and the protection box 4 can be adjusted according to actual needs.

[0025] In an optional embodiment: the transmission assembly includes two connecting rods 8 fixedly arranged on the upper wall of the sealing slide plate 7, the upper ends of the two connecting rods 8 are commonly fixedly provided with a moving sheet 9, and the side wall of the moving sheet 9 is also matched with a reciprocating screw rod 12, and the reciprocating screw rod 12 is between the two connecting rods 8. The side wall of the motor 6 is driven by a motor shaft 11, the motor shaft 11 is arranged in the protective box 4, and the motor shaft 11 and the reciprocating screw rod 12 are connected by a gear box 10.

[0026] It should be noted that when the motor 6 is turned on, the motor shaft 11 is driven to rotate, thereby driving the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, it drives the moving plate 9 at its side wall to move in the vertical direction toward the cooling water tank 13, thereby pushing the sealing slide 7 to squeeze the cooling water tank 13 to move.

[0027] In an optional embodiment: a plurality of spray heads 14 are embedded on the side wall of the telescopic cavity 5, and the spray heads 14 are pressure relief spray heads.

[0028] It should be noted that the protruding arrangement of the spray head 14 prevents the spray head 14 from affecting the movement of the telescopic cavity 5 and prevents structural conflicts. At the same time, the cooling water can be sprayed out at high pressure, thereby expanding the cooling area and improving the cooling efficiency.

[0029] In an optional embodiment: a spring 16 is fixedly connected between the clamping plate 15 and the inner wall of the cooling water tank 13 , and a water inlet is opened at the side wall of the cooling water tank 13 .

[0030] It should be noted that the telescopic chamber 5 can be pulled back into the cooling water tank 13 under the action of the spring 16 to facilitate the circulation of the device, and the cooling water in the cooling water tank 13 can be replenished in time through the water inlet.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] When the device is in use, firstly, the relative position and angle between the connecting shell 3 and the protective box 4 are adjusted according to actual needs, and the cooling liquid is injected into the cooling water tank 13 from the water inlet in advance. When the grinding wheel 2 is working, the motor 6 can be turned on to drive the motor shaft 11 to rotate, thereby driving the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, it drives the moving sheet 9 at its side wall to move toward the cooling water tank 13 in the vertical direction, thereby pushing the sealing slide 7 to squeeze the cooling water tank 13 to move. In the process of the sealing slide 7 moving downward, the telescopic cavity 5 is first pushed to move outward, At this time, the spring 16 is stretched, and the spray head 14 is still in the cooling water tank 13. As the telescopic chamber 5 continues to move, until the clamping plate 15 and the inner wall of the opening fit together, the spray head 14 moves out of the cooling water tank 13, and cooperates with the extrusion of the sealing slide plate 7 to cool the surface of the grinding wheel 2. In addition, through the outward movement of the telescopic chamber 5, the telescopic chamber 5 can protect the part where the staff observes the grinding situation to prevent direct viewing of the grinding area. While protecting the eyes, it prevents some debris from splashing, and cooperates with the extrusion of the coolant to greatly increase the practicability of the grinder.
