[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1.

[0022] 3. When the swing plate swings to the right, the multiple double-sided cams rotate at an angle of 90 degrees to slide against the connecting plate, and the connecting plate pushes the slide plate to slide in a sealed manner inside the corresponding box body to squeeze the buffer into the multiple strip-shaped air bags, so that the strip-shaped air bags are filled with the buffer and are in a filled state.

The spur gear will drive the magnetic ring to move to the right synchronously to disengage from the attracted state. The ejection spring will push the protective cover and the magnetic plate outward so that the protective cover rotates to a certain angle and contacts the side wall of the emission box. Then, the protective cover no longer covers and seals the through hole, which facilitates the operation of the X-ray fluorescence spectrometer.

[0024] 5. When the swing plate rotates from right to left, the vertical axis will rotate 90 degrees in the opposite direction, and the double-sided cam will push the rubber block to slide outward for a certain distance, so as to provide friction between the hands of subsequent users and the handle, thereby preventing the rubber block from slipping and falling off. During the sliding process, the rubber block will slide against the sweat-absorbing bristles provided on the inclined portion of the cleaning block to clean the sweat stains on the rubber block, thereby preventing the sweat stains from adhering to the rubber block and affecting the anti-slip function of the rubber block.

[0041] The interior of the arc box 18 is filled with mineral oil, and each double-sided cam 33 slides against two opposite rubber blocks 24 .

[0042] The protection mechanism includes a plurality of strip-shaped air bags 39 symmetrically embedded and fixed on the side wall of the body 1; the inner wall of the handle 3 is symmetrically fixedly connected to the box body 34; each box body 34 is sealed and slidably connected to a slide plate 36; the side wall of the slide plate 36 is fixedly connected to a return spring 35; the other end of the return spring 35 is fixedly connected to the inner wall of the box body 34; the side wall of the slide plate 36 is fixedly connected to a connecting plate 37.

[0043] A connecting tube 38 is fixedly connected to the inner wall of the box body 34, and the ends of the two connecting tubes 38 away from the box body 34 penetrate the handle 3 and the inner wall of the body 1 and are fixedly connected to a strip air bag 39. The box body 34 is filled with a buffer solution, and the double-sided cam 33 and the connecting plate 37 slide against each other.

[0044] A protective cover 48 is rotatably connected to the side wall of the launch box 2, a magnetic plate 49 is fixed to the side wall at one end of the protective cover 48, a closing groove 46 is opened on the side wall of the launch box 2, a push-out spring 47 is installed on the inner wall of the closing groove 46, a spur rack 44 is slidably connected through the inner wall of the closing groove 46, a magnetic ring 491 is fixedly connected to one end of the spur rack 44, a tension spring 45 is sleeved and fixed on the side wall of the spur rack 44, the other end of the tension spring 45 is fixedly connected to the inner wall of the launch box 2, a transmission gear 43 is rotatably connected to the inner wall of the launch box 2, and a toothed belt 41 is fixedly connected to the side wall of the connecting plate 42.

[0045] The spur rack 44 is meshed with the transmission gear 43, the toothed belt 41 is meshed with the transmission gear 43, the inner wall of the launch box 2 is rotatably connected with a conveying roller component 50, the conveying belt part of the conveying roller component 50 is bonded and installed with cleaning fluff 51, the side wall of the rotating shaft 6 is connected with the roller shaft part of the conveying roller component 50 through the transmission belt component 52, and a through hole 40 is opened on the side wall of the launch box 2.

[0046] The conveying roller component 50 includes two rollers rotatably connected to the inner wall of the launch box 2 through a roller shaft, a conveyor belt is connected between the two rollers, and the transmission belt component 52 includes a driving wheel fixedly connected to the side wall of the rotating shaft 6, and the roller shaft portion of the conveying roller component 50 is fixedly connected to a driven wheel, and the driving wheel and the driven wheel are connected by a transmission belt.

[0047] In the present invention, when the handheld X-ray fluorescence spectrometer is not in use, the protective cover 48 is first pushed to rotate, so that the protective cover 48 drives the magnetic plate 49 fixedly connected to its side wall to enter the closed groove 46. Since the magnetic plate 49 and the magnetic ring 491 have opposite polarities and magnetic attraction to each other, the magnetic plate 49 will be attracted to the magnetic ring 491, and the protective cover 48 seals and covers the through hole 40 to prevent foreign matter such as water from entering the interior of the launch box 2 to play a protective role. Then the micro motor 5 is turned on, and the output end of the micro motor 5 drives the rotating shaft 6 to rotate. On the one hand, the rotating shaft 6 will drive the conveying roller component 50 to rotate through the transmission belt component 52, so that the clean fluff 51 adhered and fixed on the conveying roller component 50 moves. On the other hand, the rotating shaft 6 will also drive the cross bar 7 fixedly connected to its side wall to rotate, so the cross bar 7 drives the connecting rod 8 connected to it to move, so that the connecting rod 8 drives the swing plate 9 connected to it to swing back and forth. Figure 5 As shown, at this time, the swing plate 9 is in a state of swinging to the left and about to reach the end of its stroke, and the end of its rightward swing is at an obliquely downward position.

[0048] like Figure 3 and Figure 5 As shown, when the swing plate 9 swings to the right, the swing plate 9 will drive the main shaft 12 and the long plate 14 to move through the rectangular block 13. Since the long plate 14 is slidably connected to the inside of the rectangular frame 15, when the swing plate 9 rotates to the lower right, the end of the long plate 14 away from the main shaft 12 will drive the inside of the rectangular frame 15 to slide to the upper right and drive the rectangular frame 15 and the first rod 16 to rotate. Under the synchronous action of the main shaft 12 moving to the lower right, when the swing plate 9 moves to the lower right to the end of the stroke, the main shaft 1 2 will drive the connecting plate 42 and the fluorescent emitter 4 to the downward position, then the fluorescent emitter 4 will be in contact with the cleaning fluff 51 adhered to the conveying roller component 50. Since the cleaning fluff 51 moves synchronously with the conveying roller component 50, the cleaning fluff 51 will wipe the lens part of the fluorescent emitter 4. Then the micro motor 5 is powered off, and the fluorescent emitter 4 will be converted from the working state located in the through hole 40 to the non-working state inserted in the cleaning fluff 51, which protects the fluorescent emitter 4.

[0049] In the process of the swing plate 9 swinging to the right, the swing plate 9 will also drive the arc rod 20 to move synchronously, so that the arc rod 20 drives the sliding plug 19 fixedly connected thereto to slide in a sealed manner inside the arc box 18, then the sliding plug 19 will draw the mineral oil inside the sliding groove 29 into the arc box 18 through the connecting pipe 21, then the driving rack 30 will slide in a sealed manner to the left inside the sliding groove 29 for a distance, then the driving rack 30 will drive the driving gear 32 meshing with it to rotate ninety degrees, then the driving gear 32 will drive multiple double-sided cams 33 to rotate ninety degrees through the vertical shaft 31, then the two protrusions of each double-sided cam 33 will rotate ninety degrees, then the two protrusions of each double-sided cam 33 will rotate with the vertical shaft 31. The rubber block 24 is disengaged, and under the action of the third spring 28, the rubber block 24 enters the cross hole 23 and contacts with the sweat-absorbing bristles 27 arranged on the inclined surfaces of the two cleaning blocks 26. The double-sided cam 33 slides against the connecting plate 37 during the rotation of ninety degrees, and pushes the slide plate 36 to slide sealedly for a distance inside the corresponding box body 34 through the connecting plate 37. Then, the slide plate 36 will squeeze the buffer solution filled inside the box body 34 into the multiple strip air bags 39, so that the strip air bags 39 are in a filled state after being filled with the buffer solution. Then, when the body 1 falls from a height, the multiple strip air bags 39 filled with the buffer solution can play a role in buffering and shock absorption.

[0050] When the handheld X-ray fluorescence spectrometer needs to be used, the micro motor 5 is turned on. The micro motor 5 drives the cross bar 7 to move through the rotating shaft 6, and the cross bar 7 drives the swing plate 9 to rotate from right to left through the connecting rod 8. Then the swing plate 9 will drive the main shaft 12 to move synchronously through the rectangular hole 11 and the rectangular block 13, and the main shaft 12 will drive the long strip plate 14 to move synchronously, and the long strip plate 14 will slide to the left inside the rectangular frame 15 until the long strip plate 14 and the limit rod 17 are in contact. At this time, the long strip plate 14, the connecting plate 42 and the fluorescent emitter 4 are all in a horizontal state. Then, when the swing plate 9 continues to rotate to the right, the rectangular block 13 will slide inside the rectangular hole 11, and the rectangular block 13 will drive the fluorescent emitter 4 to move horizontally to the left for a distance through the main shaft 12 and the connecting plate 42, so that the fluorescent emitter 4 is inserted into the through hole 40 for convenient analysis and detection operations.

[0051] When the connecting plate 42 drives the fluorescent emitter 4 to move to the left, the toothed belt 41 fixedly connected to the top wall of the connecting plate 42 will drive the transmission gear 43 meshing with it to rotate, and the transmission gear 43 will drive the spur rack 44 meshing with it to move a certain distance to the right. Then, the spur rack 44 will drive the magnetic ring 491 to move to the right synchronously, so that the magnetic ring 491 and the magnetic plate 49 are out of the attracted state. Then, under the action of the ejection spring 47, the ejection spring 47 will push the protective cover 48 and the magnetic plate 49 outward, so that the protective cover 48 rotates a certain angle and contacts the side wall of the emission box 2, and then the protective cover 48 no longer covers and seals the through hole 40, so as to facilitate the operation of the X-ray fluorescence spectrometer.

[0052] When the swing plate 9 rotates from right to left, the swing plate 9 will drive the sliding plug 19 to slide in a sealed manner inside the arc box 18 through the arc rod 20, and then squeeze the mineral oil inside the arc box 18 into the sliding groove 29, so that the driving rack 30 slides in the reverse sealing manner for a distance. Then, under the action of the driving gear 32, the vertical shaft 31 will rotate ninety degrees in the opposite direction, so that the double-sided cam 33 slides against the rubber block 24 again, and then the double-sided cam 33 will push the rubber block 24 to slide outward for a distance, which will provide friction between the subsequent user's hand and the handle 3 to prevent slipping and falling off the hand. Moreover, one end of the rubber block 24 is arranged in an arc surface, so the rubber block 24 will push the two cleaning blocks 26 to slide in the cross hole 23 for a distance, and the rubber block 24 will slide against the sweat-absorbing bristles 27 arranged on the inclined surface of the cleaning block 26, brush the sweat stains on the rubber block 24, and prevent the sweat stains from adhering to the rubber block 24 and affecting the anti-skid function of the rubber block 24.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
