When in use, pulling the support plate 8 to move it upward can make the bottoms of the first push rod 5 and the second push rod 6 approach each other, thereby driving the push rod to slide along the slide plate 18. At this time, the distance between the top plate 4 and the right side wall inside the box body 1 increases, and then the laser measuring device 3 is placed inside the box body 1, and then the support plate 8 is pressed to move it in the direction of the bottom surface of the inner wall of the box body 1. At this time, the pressure of the support plate 8 can drive the bottoms of the first push rod 5 and the second push rod 6 to move away from each other. At this time, the top plate 4 can be pushed out to make it close to the right side wall inside the box body 1. At this time, the laser measuring device 3 can be clamped, and then the position of the support plate 8 can be fixed by using the clamping assembly. When the laser measuring device 3 needs to be taken out, by loosening the clamping assembly, the elastic force of the tension spring 7 will drive the first push rod 5 and the second push rod 6 to approach each other, thereby driving the top plate 4 away from the laser measuring device 3, and then it can be taken out from the inside of the box body 1, thereby making the loading and unloading of the laser measuring device 3 convenient.

[0033] Reference Figure 2 A through hole 10 is provided in the middle of the right side of the outer wall of the box body 1. The through hole 10 can avoid obstruction to the laser measuring device 3.

[0034] Reference Figure 1 A groove 12 is provided in the middle of the top surface of the box cover 2, and a handle 11 is rotatably connected inside the groove 12. The box body 1 can be conveniently carried by the handle 11, and the handle 11 can be stored by the groove 12.

By respectively arranging the first rubber sheet 13 and the second rubber sheet 14 on both sides of the outer wall of the laser measuring device 3, it is possible to avoid damage to the laser measuring device 3 caused by excessive squeezing force of the top plate 4.

[0036] Reference Figure 4-5The bottom of the other side of the inner wall of the box body 1 is fixedly connected with a first connection seat 15, the bottom of one side of the support plate 8 is fixedly connected with a second connection seat 16, and both sides of the bottom surface of the support plate 8 are fixedly connected with third connection seats 17. The bottom of the first push rod 5 is rotatably connected to the inside of the first connection seat 15, the bottom of the second push rod 6 is rotatably connected to the inside of the second connection seat 16, and the tops of the first push rod 5 and the second push rod 6 are rotatably connected to the inside of the third connection seats 17 on both sides. The first push rod 5 and the second push rod 6 can be rotated by the cooperation between the first connection seat 15, the second connection seat 16 and the third connection seat 17 to realize the rotation between the first push rod 5 and the second push rod 6.

[0037] Reference Figure 6 The clamping assembly includes a slide bar 20 and a spring 21. The outer wall of the slide bar 20 is slidably connected to the inside of the plug plate 9. The spring 21 is located on the outer side of the slide bar 20 and between the support plate 8 and the plug plate 9. The slide bar 20 is fixedly connected to the inside of the support plate 8. A mounting groove 23 is provided inside the support plate 8, and the plug plate 9, the slide bar 20 and the spring 21 are all located inside the mounting groove 23. The front and rear sides of the left side of the inner wall of the box body 1 are both provided with a clamping groove 22, and the far sides of the plug plates 9 on both sides are respectively located inside the clamping grooves 22 on both sides, and the length of the clamping groove 22 is greater than the length of the plug plate 9. The plug plate 9 can be pushed out by the spring 21 to enter the clamping groove 22 on the inner wall of the box body 1. At this time, the height of the support plate 8 can be locked to prevent the elastic force of the tension spring 7 from driving the support plate 8 to move upward and causing the laser measuring device 3 to loosen.

[0038] Reference Figure 4-5 The bottom surface of the inner wall of the box body 1 is fixedly connected with a slide plate 18, and a slide groove 19 is provided at the bottom of the top plate 4.

Through the cooperation between the slide plate 18 and the slide groove 19, the movement direction of the top plate 4 can be guided.

[0039] Working principle: When in use, the two plug plates 9 are pulled to slide inside the support plate 8, and the two plug plates 9 are brought close to each other. At this time, the two plug plates 9 can be moved out from the inside of the card slot 22, and the support plate 8 is pulled to move it upward. At this time, the bottoms of the first push rod 5 and the second push rod 6 can be brought close to each other, thereby driving the push rod to slide along the slide plate 18, and making the top plate 4 close to the first connecting seat 15. At this time, the distance from the top plate 4 to the right side wall inside the box body 1 increases, and then the laser measuring device 3 can be placed between the two slide plates 18, and then the support plate 8 is pressed to move it in the direction of the bottom surface of the inner wall of the box body 1. At this time, the pressure of the support plate 8 can drive the bottoms of the first push rod 5 and the second push rod 6 to move away from each other, and the top plate 4 can be pushed out to make it close to the right side wall inside the box body 1. At this time, the laser measuring device 3 can be clamped, and then the plug plates 9 are released. , since the two plug plates 9 will compress the spring 21 when they are close to each other, after the two plug plates 9 are loosened, the top plate 4 can be pushed out by the elastic force of the spring 21. At this time, the plug plate 9 can be pushed into the inside of the slot 22, and then the height of the support plate 8 can be locked, thereby improving the stability of the laser measuring device 3 inside the box body 1, and when the laser measuring device 3 needs to be taken out, the two plug rings are pulled close to each other to make it move out from the inside of the slot 22, and when the bottoms of the first push rod 5 and the second push rod 6 are away from each other, the tension spring 7 will be stretched, and at this time, after the plug ring is moved out of the inside of the slot 22, the elastic force of the tension spring 7 will drive the first push rod 5 and the second push rod 6 to move close to each other, thereby driving the top plate 4 away from the laser measuring device 3, and then it can be taken out from the inside of the box body 1, thereby making the loading and unloading of the laser measuring device 3 convenient, and improving the practicality of the device.
