Correspondingly, inner wedge surfaces 16 are correspondingly arranged on two sides of the upper chuck 13, the control cylinder 12 controls the upper chuck 13 to move, and the loosening and clamping states of the upper chuck 13 are switched under the contact extrusion action of the outer wedge surfaces 15 and the inner wedge surfaces 16.

The outer side wall of the clamping block 133 is shaped as an inner wedge surface 16, cooperating with an outer wedge surface 15. Therefore, when the control cylinder 12 drives the upper chuck 13 to move upward, the inner wedge surface 16 of the clamping block 133 will move upward along the outer wedge surface 15, and since the outer wedge surface 15 is fixed, the two outer wedge surfaces 15 have a form of being narrow at the top and wide at the bottom, so that the outer wedge surface 15 will press the inner wedge surface 16 inward when the clamping block 133 moves upward, so that the two clamping blocks 133 get close to each other, and the clamping on the wavelength division assembly 01 is formed. And the control cylinder 12 drives the upper clamping head 13 to move downwards, so that the upper clamping head 13 is loosened.

The floating platform 22 is provided with a first through hole 221, when the laser assembly 02 is clamped by the clamping assembly 25, the lead plate of the laser assembly 02 passes through the first through hole 221 and extends out of the lower surface of the floating platform 22, and the lead plate 021 of the laser assembly 02 is electrified by the electrifying assembly 24, so that the laser assembly 02 emits laser.

Further, the gap between the movable block 253 and the fixed block 252 forms an angle with the width direction of the laser assembly 02, that is, the gap forms an angle with the extending direction of the first through hole 221 and the opening. Correspondingly, the side walls of the movable block 253 and the fixed block 252 for clamping the laser assembly 02 are respectively provided with a clamping groove 256 and a lead plate passing groove 257, wherein the included angle of the clamping groove 256 is 90 degrees and is consistent with the outer angle of the box-type laser assembly 02, when the movable block 253 and the fixed block 252 are clamped and folded, two opposite corners of the laser assembly 02 are respectively positioned in the two clamping grooves 256, so that the laser assembly 02 can be completely limited on the plane (horizontal plane) where the backing plate 251 is positioned through the limiting effect of the clamping grooves 256, and meanwhile, the vertical displacement is limited through the static friction force generated by clamping, and finally, the position of the laser assembly 02 relative to the lower clamp 2 is limited and confirmed.

In addition, after the clamping and positioning, the two lead plates pass through the slots 257 and are opposite to the two ends of the first through hole 221, so that a channel through which the lead plate 021 passes is made, and therefore when the laser assembly 02 needs to be taken out, the adjusting bolt 255 only needs to be slightly loosened to pull out the laser assembly 02, and the operation can be simplified.

When the lead plate 021 is in place, the power-on structure is displaced, and the power-on lead 243 is contacted with the pin, so that the power-on operation of the laser component 02 can be completed.

The power-on structure comprises a top block 244 and a bottom plate 245 which are integrally connected, the top block 244 is slidably arranged in a sliding groove 246 formed in the middle of the power-on platform 241, and two sides of the bottom plate 245 are respectively movably sleeved on guide columns 247 on two sides of the power-on platform 241.

The top block 244 is fixedly connected with a hand-held pull rod 248, and when the power is on, only the pull rod 248 is pushed, so that the top block 244 and the bottom plate 245 can be pushed to slide upwards inside the level platform 241, and the power-on lead 243 is contacted with the pin. When the laser assembly 02 needs to be removed, the pull rod 248 is pulled outward to break the contact of the upper electrical lead 243.
