[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0025] like Figure 1-11 As shown, a device for dotting a lens of a focimeter includes a first dotting device 1, a second dotting device 2, and a third dotting device 3. The first dotting device 1, the second dotting device 2, and the third dotting device 3 are connected by a connecting plate 4. The first dotting device 1, the second dotting device 2, and the third dotting device 3 each include a sleeve 100, a dotting assembly 200, and a protective assembly 300. The dotting assembly 200 is disposed inside the sleeve 100, and the protective assembly 300 is disposed at one end of the dotting assembly 200 and is connected to the sleeve 100. Sliding connection; the dotting component 200 includes a pen barrel 201, and the pen barrel 201 is provided with a first limiting step 205. The upper side of the first limiting step 205 is connected to one end of the first spring 203, and the other end of the first spring 203 is connected to the sleeve 100. The lower side of the first limiting step 205 is connected to one end of the second spring 204, and the other end of the second spring 204 is connected to the protective component 300. The bottom of the pen barrel 201 is connected to the seal pen head 202. The inside of the pen barrel 201 is hollow, and the hollow part is filled with printing ink.
[0026] The sleeve 100 is connected to the pen holder 201 via a screw 101. The stamp pen head 202 is cylindrical.
[0027] The protection assembly 300 includes a pen tip sheath 301, a groove and a through hole are provided at the bottom of the pen tip sheath 301, a first pin 302 and a second pin 303 are provided inside the pen tip sheath 301, and the first pin 302 and the second pin 303 pass through the through holes of the first magnet 304 and the second magnet 305 respectively and are installed in the groove of the pen tip sheath 301 (as shown in FIG. Figure 10-11 As shown), the stamp pen tip 202 passes through the inside of the pen tip sheath 301, and a second limiting step 306 is provided on the top of the sleeve 100. The second limiting step 306 passes through the groove at the bottom of the sleeve 100 and is slidably connected to the sleeve 100.
[0028] It should be noted that the structure of the present invention completes the dotting by pressing down the sleeve 100 . Continue to press the sleeve 100 down until the pen tip cover 301 contacts the lens. At this time, continue to press the sleeve 100 down so that the first spring 204 inside the structure begins to compress, and at the same time, the pen tip cover 301 moves upward in the sleeve 100. The first magnet and the second magnet 204 installed in the pen tip cover 301 contact the stamp pen tip 202 and are forced to open. Continue to compress the first spring 204 until the internal magnets are completely opened, and the stamp pen tip 202 is exposed to complete the dotting. When dotting on a lens with a large curvature, repeat the above process to complete the printing of the point located in the center of the lens. The points on the left and right sides still need to continue to press down the sleeve 100 for printing. At this time, the structure inside the middle part of the device begins to compress the first spring 203. As the first spring 203 compresses the protection component 300, the pen shaft 201 and the stamp pen tip 202 move upward together, and the structures on the left and right sides of the device move downward together to complete the dotting on the lens. After the dotting is completed, the elastic force generated by the compression of the first spring 203 and the second spring 204 will cause the various components inside the structure to reset themselves, which is simple and convenient to use.
[0029] It should be noted that this structure has three pen devices placed in parallel. When dotting lenses with large curvature, the traditional dotting device has a simple internal structure. The pen is fixed inside the sleeve and cannot move. Therefore, when dotting, it can only print clearly in the center of the lens. The pen tips cannot touch the lens due to insufficient distance on both sides, so the printed dots are not clear. The device of the utility model is equipped with a spring inside to allow the pen to move freely. When dotting lenses with large curvature, continuously pressing down the sleeve can make all three pen tips touch the lens. Therefore, the dots printed on both sides will be clearer than before. Figure 6-7 shown.
[0030] It should be further explained that the sleeve 100 is pressed down to compress the second spring 204, the pen tip cover 301 moves upward, the pen body 201 and the stamp pen tip 202 move downward, and the stamp pen tip 202 pushes down the closed first magnet 304 and second magnet 305 to contact the lens for dotting. After the dotting is completed, the sleeve 100 is released, and the elastic force generated by the compression of the two springs causes the sleeve 100, the pen body 201 and the pen tip cover 301 to reset themselves. Since the first magnet 304 and the second magnet 305 are both strong magnets and the distance between them when opened is very small, the two magnets will close automatically under the action of the magnetic force when the pen body resets itself and moves upward after the dotting is completed. Figure 8-9 shown.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
