The scanner 3 is provided with a latch 31, and the latch 31 is engaged with the clip 111.

The working principle is as follows:

when the scanner 3 starts to work, the bottom of the scanner 3 is placed right above the first baffle 21, the scanner 3 with the lens is placed outwards, then the first baffle 21 is pressed downwards forcibly, the supporting spring 24 is compressed, then pressure is applied to the third baffle 23, the third baffle 23 is pressed downwards along with the supporting spring 24 under the action of pressure, after the third baffle 23 is moved downwards, the clamping block 111 originally clamping the third baffle 23 is clamped inwards under the action of the clamping spring 112, at the moment, the scanner 3 is continuously pressed downwards until the clamping block 31 is pressed downwards below the clamping block 111, at the moment, the scanner 3 is released, the clamping block 111 clamps the scanner 3 under the action of the clamping spring 112, and the scanner 3 is fixed on the movable base 1 under the interaction of the clamping block 31 and the clamping block 111; when the scanner 3 is installed, the first baffle plate 21 is pressed downwards to generate pressure on the second baffle plate 22, the second baffle plate 22 is rotatably connected with the first baffle plate 21, the lower end of the second baffle plate 22 is rotatably connected with one end of the extension rod 25, the second baffle plate 22 can rotate outwards when being pressed, the second baffle plate 22 rotates to stretch the extension rod 25, and the extension rod 25 plays a supporting role in supporting the second baffle plate 22; when the scanner 3 is moving and scanning, after colliding with an object, the second baffle 22 will contact with the obstacle at first, so as to prevent the lens of the scanner 3 from being damaged, and because of the existence of the damping spring 13, the vibration of the scanner 3 can be reduced, and the measurement accuracy of the scanner 3 is improved.

After scanner 3 installs, because No. three baffle 23 is pushed down, No. three baffle 23 contacts lug 175, push down lug 175, lug 175 exerts pressure to the one end of connecting plate 172 thereupon, because connecting plate 172 cup joints on axostylus axostyle 171, under the leverage, the other end of connecting plate 172 lifts thereupon to lift the clutch blocks 174 who connects at the other end of connecting plate 172, clutch blocks 174 lifts, does not contact with truckle 18, makes truckle 18 can rotate, thereby makes mobile base 1 can remove. When the scanner 3 works, the motor 14 is started to drive the first gear 152 to rotate, and the belt 151 is connected with the first gear 152 and the second gear 153, so that the first gear 152 drives the second gear 153 to rotate when rotating, and the second gear 153 is connected to the rotating shaft of the fan 16, so that the fan 16 is driven to rotate, and air flow is generated to perform dust cleaning and heat dissipation on the scanner 3.

When the work is accomplished, when dismantling scanner 3, to the back that removes 1 external use hand push scanner 3 of base, release removal base 1 with scanner 3, after scanner 3 is released, No. three baffle 23 rises under damping spring 13's effect, extrude clamp splice 111 toward both sides, because the top loses pressure, the tension spring 26 of connection in extension rod 25 one end begins the shrink, inwards pull extension rod 25, thereby inwards pull the one end of No. two baffles 22, supporting spring 24 promotes No. one baffle 21 rebound under the spring action simultaneously, No. one baffle 21 drives the other end removal of No. two baffles 22, thereby make protection machanism 2 reset to the position when not installing scanner 3. When the third baffle 23 moves upward, the bump 175 and the connecting plate 172 lose pressure, one end of the connecting plate 172 rises under the action of the return spring 173, and the other end of the connecting plate 172 falls along with the action of the lever, so that the friction block 174 falls, and the friction block 174 contacts with the caster 18, so that the caster 18 stops rotating, and the mobile base 1 is in a static state when not in operation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the embodiments and descriptions given above are only illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claims.
