[0025] See also Figure 1-5 The utility model provides a technical solution: a protective device for a clamping laser head, comprising: a fixing plate 1, a knob 2 is arranged above the fixing plate 1, a plurality of sliding holes 3 are opened on the outer surface of the fixing plate 1, a plurality of sliding grooves 4 are opened on the outer surface of the knob 2, a plurality of sliding holes 3 and a plurality of sliding grooves 4 are movably embedded with sliding rods 5 on the inner surfaces, a plurality of sliding rods 5 are fixedly connected with clamping blocks 6 at the bottom, a plurality of clamping blocks 6 are arranged with lasers 7 on the outer surfaces, a sliding hole three 8 is opened on the outer surface of the fixing plate 1, a sliding block 9 is movably embedded in the inner surface of the sliding hole three 8, a positioning rod 11 is fixedly connected to the top of the sliding block 9, a spring 10 is fixedly connected to the outer surface of the sliding block 9, which avoids the removal of too many bolts, improves the production efficiency, reduces the labor intensity of the staff, and shortens the production cycle.

[0026] like Figure 1-5 As shown, a plurality of baffles 12 are fixedly connected to the outer surface of the fixed plate 1, a working block 13 is movably embedded in the outer surfaces of the plurality of baffles 12, and a gasket 14 is movably embedded in the inner surfaces of the plurality of working blocks 13, thereby preventing the laser 7 from colliding with nearby equipment and causing damage to the laser 7, thereby increasing the service life of the laser 7.

[0027] like Figure 1-5 As shown, the spring 10 is fixedly connected to the inner wall of the sliding hole 3 8. The spring 10 can provide power for the slider 9 to move in the reverse direction when the positioning rod 11 is not pulled, so that the slider 9 moves in the reverse direction.

[0028] like Figure 1-5 As shown, the outer surfaces of the opposite sides of multiple gaskets 14 and baffles 12 are fixedly connected with fixed blocks 15, and the multiple fixed blocks 15 are provided with connecting plates 16 through positioning pins. The fixed blocks 15 can position the movement trajectory of the connecting plates 16 to provide a good working environment for the connecting plates 16.

[0029] like Figure 1-5 As shown, the plurality of connecting plates 16 are evenly divided into four groups, and connecting rods 17 are movably embedded in the inner surfaces of the four groups of connecting plates 16. The connecting plates 16 can push the connecting rods 17 to move when the fixing block 15 is displaced.

[0030] like Figure 1-5 As shown, the plurality of connecting rods 17 are evenly divided into two groups, and the outer surfaces of opposite sides of the two groups of connecting rods 17 are fixedly connected to the limiting blocks 18 . The connecting rods 17 can move the limiting blocks 18 under the drive of the connecting plate 16 .

[0031] like Figure 1-5 As shown, a limiting groove 20 is provided on one side of the working block 13 close to the two limiting blocks 18, and the two limiting blocks 18 are movably embedded in the inner surfaces of the two limiting grooves 20.

The springs 19 can provide power for the reverse movement of the limit blocks 18 when the torque of the movement of the laser 7 is reduced, so that the limit blocks 18 move in the reverse direction.

[0033] Working principle: This device is a protective device for a clip-on laser head. When the laser 7 needs to be replaced, the positioning rod 11 is manually pulled to make the positioning rod 11 leave the groove of the knob 2. When the positioning rod 11 moves, it will drive the slider 9 to move on the inner surface of the sliding hole 3 8 on the fixed plate 1, and at the same time squeeze the spring 10 so that the spring 10 obtains elastic potential energy. Then the knob 2 is manually rotated to make the knob 2 drive the multiple sliding rods 5 to move on the inner surface of the multiple sliding holes 3 through the multiple sliding grooves 4, so that the multiple sliding rods 5 drive the multiple clamping blocks 6 to approach the outer surface of the laser 7 and clamp it. When the multiple clamping blocks 6 clamp the laser 7, the positioning rod 11 is released, and the spring 10 releases the elastic potential energy, so that the slider 9 drives the positioning rod 11 to move in the opposite direction, so that the positioning rod 11 is re-stuck in the tooth protrusion of the knob 2, thereby realizing self-locking and avoiding the removal of too many screws. The bolt improves production efficiency, reduces the labor intensity of staff, and shortens the production cycle. When the laser 7 is about to hit the nearby equipment during movement, the gasket 14 hits the nearby equipment first and stops moving, while the baffle 12 will continue to move with the movement of the laser 7, so that the connecting plate 16 on the fixed block 15 drives the connecting rod 17 to move, and the connecting rod 17 drives the limit block 18 to move on the inner surface of the limit groove 20 on the working block 13, and squeezes the spring 2 19, so that the spring 2 19 obtains elastic potential energy. When the force of the laser 7 movement is reduced, the spring 2 19 will release the elastic potential energy, so that the limit block 18 moves to the initial position, and then the baffle 12 drives the laser 7 to move to the initial position, thereby achieving buffering, avoiding the laser 7 from hitting the nearby equipment and damaging the laser 7, and improving the service life of the laser 7.
