[0047] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0048] like Figure 1-4 As shown, the portable multifunctional laser cleaning pen includes a laser cleaning pen body 1; a translucent pen head 101 is provided at the top end of the laser cleaning pen body 1, and a mounting chamber 102 is provided at the bottom end of the laser cleaning pen body 1; it also includes: a cover 3, which is provided on the translucent pen head 101, and the cover 3 is connected to a flip and clamping mechanism 2 installed on the laser cleaning pen body 1, and the cover 3 is covered or leaves the top surface of the translucent pen head 101 through the flip and clamping mechanism 2; a laser head 9, which is detachably installed in the interior of the mounting chamber 102, and an elastic pressure piece is provided in the interior of the mounting chamber 102, and the elastic pressure piece presses the laser head 9.

[0049] like Figure 1-2As shown, as a specific technical solution, the flipping and clamping mechanism 2 includes a fixed ring 201, an elastic telescopic rod and a hinge shaft 206; the fixed ring 201 is fixedly sleeved on the outer wall of the laser cleaning pen body 1, the number of the elastic telescopic rods is two, and one end of the two elastic telescopic rods is provided with a hinge shaft 206, the bottom end of the elastic telescopic rod is rotatably connected to the fixed ring 201 through the hinge shaft 206, and the top end of the elastic telescopic rod is connected to the cover 3. The elastic telescopic rod includes an articulated arm 202, a fixed guide rod 203, a movable sleeve 204, and a first spring 205. The articulated arm 202 is connected to the hinge shaft 206, and the end of the articulated arm 202 away from the hinge shaft 206 is fixedly connected to one end of the fixed guide rod 203. The inner wall of the movable sleeve 204 is matingly connected to the wall of the fixed guide rod 203. The first spring 205 is disposed within the movable sleeve 204. The fixed guide rod 203 and the movable sleeve 204 are elastically connected via the first spring 205. The top end of the movable sleeve 204 is fixedly connected to the cover 3. One end of the first spring 205 is fixedly connected to the inner wall of the movable sleeve 204, and the other end of the first spring 205 is fixedly connected to one end of the fixed guide rod 203. A magnetic rubber pad 301 is fixedly laid on the bottom surface of the cover 3, and a grip block 4 is fixedly connected to the top surface of the cover 3. An iron block 6 is fixedly mounted on the outer wall of the laser cleaning pen body 1.

[0050] like Figure 1 As shown, the cover 3 covers the translucent pen tip 101 for protection. At this time, the first spring 205 is in a stretched state, but not fully stretched, providing elastic force for the cover 3, so that the cover 3 and the magnetic rubber pad 301 press the translucent pen tip 101, providing protection and shielding, and improving the sealing of the protection.

[0051] In the process of removing the shield, the cover 3 is moved upward by pulling the grip 4, and the movable sleeve 204 moves with the cover 3, while stretching the first spring 205 to increase the stretching amount of the first spring 205; then the grip 4 is pulled to rotate the flip pressing mechanism 2 through the hinge shaft 206, so that the cover 3 leaves the light-transmitting pen head 101, and the cover 3 is aligned with the iron block 6, and then the grip 4 is released, and the first spring 205 contracts and resets until it is as shown in FIG. Figure 2 As shown, the magnetic rubber pad 301 contacts the iron stopper 6, and the two are magnetically attracted to provide a limit. At the same time, the first spring 205 still has a tensile elastic force, but the tensile elastic force is less than Figure 1 In this state, the elastic force of the first spring 205 causes the magnetic rubber pad 301 to press the iron stopper 6, providing a friction limiting force, thereby further improving the limiting effect.

[0052] When protecting the translucent pen tip 101 again, the elastic telescopic rod is extended by loosening the grip block 4, and the flipping and pressing mechanism 2 is flipped through the hinge shaft 206, and the cover 3 is moved to the top of the translucent pen tip 101. The grip block 4 is released, and the magnetic rubber pad 301 is pressed and covered on the translucent pen tip 101.

[0053] like Figure 1 、 Figure 3 as well as Figure 4 As shown, the bottom end of the installation chamber 102 is open, and a positioning groove 5 is provided on the wall of the installation chamber 102. The laser head 9 is connected to the installation chamber 102 in a coordinated manner. A fixed shaft 7 is fixed to the shell wall of the laser head 9, and the fixed shaft 7 is placed in the positioning groove 5. The positioning groove 5 is composed of a vertical groove 501 and an arcuate groove 502. The bottom end of the vertical groove 501 is open, and the top end of the vertical groove 501 is connected to one end of the arcuate groove 502; the width of the vertical groove 501 is greater than the width of the arcuate groove 502. An end block 8 is fixedly installed in the end of the arcuate groove 502 away from the vertical groove 501. The end block 8 has a slot. The fixed shaft 7 is fixed to an arcuate iron seat 13. The arcuate iron seat 13 is inserted into the slot, and the arcuate iron seat 13 is magnetically connected to the permanent magnet 14 fixedly installed in the slot. The elastic pressure member includes a fixed inner seat 10, a second spring 11, and a pressure ring 12. The fixed inner seat 10 is fixedly installed in the installation chamber 102. The fixed inner seat 10 is elastically connected to the pressure ring 12 via the second spring 11, and the pressure ring 12 is pressed tightly against the laser head 9. There are multiple second springs 11, and the multiple second springs 11 are arranged in an annular array and attached to the pressure ring 12. One end of the second spring 11 is fixedly connected to the fixed inner seat 10, and the other end of the second spring 11 is fixedly connected to the pressure ring 12.

[0054] like Figure 1 and Figure 3 As shown, at this time, the laser head 9 is in the installed state. When disassembling, the fixed shaft 7 is pushed to make the fixed shaft 7 slide in the arc groove 502, and the arc iron seat 13 is pulled out from the end block 8. The arc iron seat 13 is separated from the permanent magnet 14 until the fixed shaft 7 moves to the junction of the vertical groove 501 and the arc groove 502. Then, the compression elastic force of the second spring 11 is used to push the laser head 9 through the pressure ring 12, so that the laser head 9 is pushed out from the bottom opening of the installation chamber 102, and the fixed shaft 7 leaves the bottom of the vertical groove 501, completing the disassembly.

[0055] When installing the laser head 9, align the laser head 9 with the bottom opening of the installation chamber 102, align the fixed shaft 7 with the bottom end of the vertical groove 501, move the fixed shaft 7, and move the fixed shaft 7 to the intersection of the vertical groove 501 and the arc groove 502. Move the laser head 9 into the installation chamber 102, and at the same time push the pressure ring 12 to compress the second spring 11, and then push the fixed shaft 7 to move the fixed shaft 7 toward the end of the arc groove 502 away from the vertical groove 501 until the arc iron seat 13 is inserted into the slot of the end block 8. The arc iron seat 13 and the permanent magnet 14 are magnetically attracted to complete the limit after installation.

[0056] The present invention is not limited to the above-described embodiments. Any changes in shape or structure fall within the scope of protection of the present invention. The scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications shall fall within the scope of protection of the present invention.
