DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1-2 As shown, an endoscopic ruler according to an embodiment of the present invention includes an operating part 10, a connecting tube 20 and a measuring tube 30, wherein a connecting tube 20 is arranged between the operating part 10 and the measuring tube 30, the measuring tube 30 is a retractable measuring tube 30, and scale lines are evenly arranged on the outer surface of the measuring tube 30, a rotating sleeve 40 is arranged on the outer side of one end of the connecting tube 20 close to the measuring tube 30, and a transition plate 50 for adjusting the inclination angle of the measuring tube 30 is arranged on one side of the rotating sleeve 40.

[0018] With the aid of the above technical solution, the operating part 10 can be used for handheld operation. A handle and a number of control buttons are fixed on the outside of the operating part 10, so that contactless operation can be realized. The retractable measuring tube 30 is driven to extend by a built-in power supply, so that measurement can be conveniently performed. The scale lines on the surface of the measuring tube 30 can help people to observe clearly, and thus timely understand the spacing of the objects to be measured. At the same time, the rotating sleeve 40 can be easily rotated, thereby driving the rotation of the measuring tube 30. At the same time, the transition plate 50 with adjustable inclination angle of the measuring tube 30 can adjust the inclination angle of the measuring tube 30, so as to drive the measuring tube 30 to rotate inside the joint to ensure that the measuring end can fit to the measured tissue. Direct measurement reduces the measurement links, thereby reducing the measurement error, and the fit is reliable, thereby improving the measurement accuracy and efficiency.

[0019] like Figure 2 As shown, a gear 1 41 is fixed to one side of the outer side of the rotating sleeve 40, and the gear 1 41 is connected to the output shaft of the motor 2. The motor 2 is fixed to the outer side of the rotating sleeve 40. An arc gear 2 42 matched with the gear 1 41 is provided on one side of the gear 1 41, and the arc gear 2 42 is slidably connected to the outer side of the rotating sleeve 40. One end of the arc gear 2 42 is movably connected to one side of the transition plate 50, and the middle part of the transition plate 50 is movably connected to the rotating sleeve 40 through a connecting rod 43; the rotation of the motor 2 is controlled by an external control button, so that the rotation of the motor 2 drives the rotation of the gear 1 41, and the rotation of the gear 1 41 drives the rotation of the arc gear 2 42, and then the rotation of the arc gear 2 42 drives the rotation of the transition plate 50, so that the angle of the transition plate 50 can be adjusted, and then the inclination angle of the measuring cylinder can be adjusted, which is more convenient for measurement.

[0020] like Figure 2 As shown, an arc-shaped hollow groove 44 is provided on the surface of the arc-shaped gear 2 42, and a limiting column 45 adapted to the hollow groove 44 is fixed to the outer side of the rotating sleeve 40; the limiting column 45 allows the arc-shaped gear 2 42 to slide only along the direction of the arc-shaped groove, thereby driving the inclination of the transition plate 50, and further driving the inclination of the measuring tube 30.

[0021] like Figure 2 As shown, the other side of the transition plate 50 is fixed to the side of the rotating sleeve 40 via a spring 46 ; the spring 46 can support and connect the transition plate 50 , thereby increasing the stability of the transition plate 50 .

[0022] like Figure 1As shown, a motor 11 is fixed to one side of the interior of the operating portion 10, and the output shaft of the motor 11 is connected to a bevel gear 12, and a bevel gear 2 13 matched with the bevel gear 12 is provided on one side of the bevel gear 12, and a rotating shaft 14 is fixed to one side of the bevel gear 2 13, and one end of the rotating shaft 14 passes through the connecting tube 20 and extends to the interior of the rotating sleeve 40 and is fixed to the rotating sleeve 40; the operation of the motor 11 can be controlled by an external control button, and the operation of the motor 11 drives the rotation of the bevel gear 12, and the rotation of the bevel gear 12 drives the rotation of the bevel gear 2 13, and then the rotation of the rotating shaft 14 is driven by the rotation of the bevel gear 2 13, and the rotating shaft 14 is fixed to the interior of the rotating sleeve 40, and then the rotation of the rotating shaft 14 drives the rotation of the rotating sleeve 40.

[0023] like Figure 1 As shown, the outer side of the rotating shaft 14 located inside the connecting tube 20 is provided with a ferrule 141 which is adapted to the rotating shaft 14, and both ends of the ferrule 141 are fixed to the inner wall of the connecting tube 20 by support columns 142, and the ferrule 141 is connected to the rotating shaft 14 by a bearing; the rotating shaft 14 can be fixed more stably inside the connecting tube 20 by the ferrule 141 and the support column 142, and the ferrule 141 is connected to the rotating shaft 14 by a bearing, which can facilitate the rotation of the rotating shaft 14, so that the fixation of the ferrule 141 will not be affected when the rotating shaft 14 rotates.

[0024] like Figure 1 As shown, the rotating sleeve 40 is connected to the outer side of the connecting pipe 20 via a bearing. The bearing connection prevents the connecting pipe 20 from rotating when the rotating sleeve 40 rotates, making the rotation of the rotating sleeve 40 more convenient.

[0025] In summary, with the aid of the above technical solution of the present invention, by inserting the measuring tube 30 into the part to be measured, the measuring tube 30 can be extended by the telescopic measuring tube 30, so that the measurement is more convenient. At the same time, the operation of the motor 11 and the motor 2 can be conveniently controlled by the external control button during measurement; the rotation of the motor 2 drives the rotation of the gear 1 41, and the rotation of the gear 1 41 drives the rotation of the arc gear 2 42, and then the rotation of the arc gear 2 42 drives the rotation of the transition plate 50, and the angle of the transition plate 50 can be adjusted, and then the transition plate 50 is driven to adjust the inclination angle of the measuring tube, which can improve the measurement accuracy; at the same time, the operation of the motor 11 drives the rotation of the bevel gear 1 12, and the rotation of the bevel gear 12 drives the rotation of the bevel gear 2 13, and then the rotation of the bevel gear 2 13 drives the rotation of the rotating shaft 14, the rotating shaft 14 is fixed to the inside of the rotating sleeve 40, and then the rotation of the rotating sleeve 40 is driven by the rotation of the rotating shaft 14, thereby driving the rotation of the measuring tube 30, and then the measurement accuracy is improved by the rotation of the measuring tube 30 and the adjustment of the inclination angle.
