[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] A vernier caliper for easy reading comprises: a main scale 111, a reading structure 2 is arranged above the main scale 111, a mounting structure 3 is arranged at the front end of the main scale 111, the reading structure 2 comprises a fixing plate 211, the fixing plate 211 is fixedly arranged at the front end of the main scale 111, an adjusting plate 212 is slidably connected to the front end of the main scale 111, two groups of scale lines 213 are arranged on the surface of the main scale 111, a mounting rod 215 is installed inside the adjusting plate 212, a first connecting rod 216 is fixedly connected to the rear end of the mounting rod 215, and the first connecting rod 216 is fixedly connected to the rear end of the mounting rod 215. A second connecting rod 217 is fixedly connected to the side wall of the rod 216, and a magnifying glass 218 is connected to the end of the second connecting rod 217 away from the first connecting rod 216. Through this design, when using the vernier caliper, the adjustment plate 212 is slid, and the object to be measured is clamped by the fixed plate 211 and the adjustment plate 212. A mounting rod 215 is installed on the adjustment plate 212. Using the magnifying glass 218 installed on the mounting rod 215, the scale on the scale line 213 can be magnified when read by the human eye to avoid inaccurate reading.

[0023] Furthermore, a ruler 214 is fixedly connected to the upper end of the adjustment plate 212, and the pointer of the ruler 214 is set above the scale line 213. The ruler 214 is below the magnifying glass 218. Through this design, the ruler 214 is fixedly connected to the upper end of the adjustment plate 212, and the position indicated by the ruler 214 is the position of the scale on the scale line 213, making the reading more accurate.

[0024] Furthermore, a rubber pad 219 is provided on the outer wall of the right end of the main scale 111. Through this design, when the vernier caliper is used, the rubber pad 219 is held by the hand to increase friction so that the caliper will not slip during use.

[0025] Furthermore, the mounting structure 3 includes an insertion rod 311, which is inserted into the mounting rod 215 and can slide inside the adjustment plate 212. A pull rod 312 is fixedly connected to the upper end of the insertion rod 311, and the pull rod 312 can slide in a sliding cavity opened inside the adjustment plate 212. The end of the insertion rod 311 away from the mounting rod 215 is inserted into an insertion cavity 313, and the insertion cavity 313 is opened inside the adjustment plate 212. Through this design, when the vernier caliper is used to install the mounting rod 215, the pull rod 312 can be pulled to drive the insertion rod 311 to move in a direction away from the mounting rod 215, and then the mounting rod 215 is inserted into the adjustment plate 212, and then the insertion rod 311 is restored to its original position, and the mounting rod 215 and the magnifying glass 218 installed thereon can be installed.

[0026] Furthermore, one end of the insertion rod 311 away from the mounting rod 215 is fixedly connected to a spring 314, and one end of the spring 314 away from the insertion rod 311 is fixedly connected to the inner wall of the insertion cavity 313. Through this design, when the vernier caliper is used to install the mounting rod 215, the pull rod 312 can be pulled to drive the insertion rod 311 to move in a direction away from the mounting rod 215, and then the mounting rod 215 is inserted into the adjustment plate 212. At this time, the spring 314 is in a compressed and force-accumulating state. By releasing the pull rod 312, the elastic force of the spring 314 can be used to automatically drive the insertion rod 311 into the mounting rod 215, so that the mounting rod 215 and the magnifying glass 218 installed thereon can be installed.

[0027] Furthermore, a slider 315 is fixedly connected to the side wall of the insertion rod 311, and the slider 315 is slidably set inside the slide groove 316. The slide groove 316 is opened inside the adjustment plate 212. Through this design, when the insertion rod 311 moves, the slider 315 moves synchronously inside the slide groove 316, thereby realizing the limiting effect on the insertion rod 311 and making its movement more stable.

[0028] Working principle:

[0029] When using the vernier caliper, slide the adjustment plate 212, and clamp the object to be measured with the fixed plate 211 and the adjustment plate 212. At this time, the scale 214 on the adjustment plate 212 points to a scale on the scale line 213. A mounting rod 215 is installed on the adjustment plate 212. The magnifying glass 218 installed on the mounting rod 215 is used to magnify the point pointed by the scale 214. The scale on the scale line 213 can be magnified when read by the human eye to avoid inaccurate reading.

[0030] When using the vernier caliper to install the mounting rod 215, the pull rod 312 can be pulled to drive the insertion rod 311 to move away from the mounting rod 215, and then the mounting rod 215 can be inserted into the adjustment plate 212. At this time, the spring 314 is in a compressed and force-accumulating state. The pull rod 312 is released, and the elastic force of the spring 314 can be used to automatically drive the insertion rod 311 into the mounting rod 215, so that the mounting rod 215 and the magnifying glass 218 installed thereon can be installed, and the operation is now completed.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
