DETAILED DESCRIPTION
[0022] The present invention will be described in further detail below with reference to the accompanying drawings.
[0023] Example:
[0024] Reference Figure 1-2The utility model discloses a measuring tool capable of quickly detecting product dimensions, comprising a fixed plate 1, wherein two storage slots 2 are provided in the fixed plate 1 relative to each other, a ruler 3 is slidably inserted into the storage slot 2, and a positioning assembly 4 is provided at the lower end of the fixed plate 1 and the lower end of the ruler 3. The positioning assembly 4 comprises two limiting plates 41, which are respectively mounted on the lower end of the fixed plate 1 and the lower end of the ruler 3. A placement slot 42 is provided in the fixed plate 1, and two through holes 43 are provided on the inner wall of the placement slot 42 relative to each other, and the interiors of the two through holes 43 are communicated with the interiors of the corresponding placement slots 42. A push rod 44 is slidably inserted into the through hole 43, and the outer peripheral wall of the push rod 44 is interference fit with the inner wall of the corresponding through hole 43. An elastic unit 45 is provided on the outer peripheral side of the push rod 44, and the elastic unit 45 is located outside the limiting plate 41. The elastic unit 45 is composed of three parts: a spring 451, a first push plate 452, and a second push plate 453. The first push plate 452 and the second push plate 453 are sleeved on the outer peripheral side of the corresponding push rod 44, and the spring 451 is provided between the corresponding first push plate 452 and the corresponding second push plate 453. The first push plate 452 is slidingly connected to the corresponding push rod 44, and the second push plate 453 is threadedly connected to the corresponding push rod 44. The first push plate 452 and the fixed plate 1 are fixedly connected by bolts. The two ends of the spring 451 are respectively rotatably connected to the corresponding first push plate 452 and the corresponding second push plate 453. A soft block 46 is fixedly installed at one end of the push rod 44 located in the placement groove 42, and the soft block 46 is arc-shaped on the side away from the corresponding push rod 44. The push rod 44 is isolated from the shaft parts by the soft block 46, and the friction between the soft block 46 and the shaft parts is enhanced by the arc surface of the soft block 46. The push rod 44 adjusts the distance between the first push plate 452 and the second push plate 453, thereby adjusting the tension of the spring 451, and then the push rod 44 is pushed to move toward the middle of the fixed plate 1 through the elastic member, thereby enhancing the squeezing force of the soft block 46 on the shaft parts.
[0025] A measuring assembly 5 is installed within the fixed plate 1. The measuring assembly 5 comprises several support rods 51, which are slidably disposed in the middle of the fixed plate 1 and are evenly distributed within the fixed plate 1. The diameter of the support rods 51 is set at 1 mm, and the spacing between the support rods 51 is set at 1 mm. Graduations are provided on the outer circumference of the support rods 51, and the support rods 51 are interference-fitted with the fixed plate 1. A soft rod 52 is fixed to the bottom end of the support rod 51. The soft rod 52 isolates the support rods 51 from the shaft components, preventing the corners of the support rods 51 from contacting the surface of the shaft components.
[0026] When the device is in use, the shaft part is fixed at a suitable position on the lower side of the fixing plate 1 by the positioning component 4, and the length and diameter of the shaft part are measured by the measuring component 5 and the ruler 3.
[0027] The working principle of the above embodiment is as follows: when using the device, the second push plate 453 is rotated to adjust the distance between the first push plate 452 and the second push plate 453, and then the blade 3 is pulled out from the storage tank 2, and then the shaft part is placed between the two fixed plates 1, and the distance between the two fixed plates 1 is adjusted so that the two ends of the shaft part are respectively inserted between the two soft blocks 46. At this time, the length of the shaft part can be obtained based on the blade 3, and the elastic unit 45 drives the push rod 44 to move to the middle position of the fixed plate 1, thereby driving the soft block 46. The arc surface fits with the outer peripheral wall of the shaft part, and then the device is placed on the operating table. The position of the push rod 44 in the through hole 43 is adjusted so that the bottom end of the shaft part and the bottom end of the fixed plate 1 are in contact with the table top of the operating table. Finally, the support rod 51 is pressed to make part of the soft rod 52 in contact with the outer peripheral wall of the shaft part, and the other part of the soft rod 52 in contact with the table top of the operating table. The diameter data between the various parts of the shaft part are obtained by comparing the scale on the support rod 51 and the spacing between the raised support rods 51.
[0028] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
