The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figure 1-Figure 4 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 is a side view of the first embodiment of the utility model, Figure 3 The utility model Figure 2 AA line section view, Figure 4 The utility model Figure 3 Enlarged view of the local structure at point B.

[0022] The utility model provides a single-handed acupuncture needle handle tightness detection device, including a fixed seat 101, a dynamometer 102, a guide assembly 103 and a clamping assembly 104, the guide assembly 103 includes a turntable 105, a mounting plate 106, a threaded rod 107 and a limit ring 108, the fixed seat 101 includes a fixed block 109 and a slide rail 110, the dynamometer 102 includes a mounting frame 111, a force measuring body 112 and a force measuring push rod 113, and the clamping assembly 104 includes a slider 114, a clamping plate 115 and two fastening screws 116.

[0023] According to this specific embodiment, the clamping assembly 104 is slidably connected to the fixed seat 101, the dynamometer 102 is fixedly connected to the fixed seat 101, the limit ring 108 is fixedly connected to the threaded rod 107, the turntable 105 is fixedly connected to the threaded rod 107, the threaded rod 107 is rotatably connected to the mounting plate 106, the mounting plate 106 is fixedly connected to the fixed seat 101, the slide rail 110 is fixedly connected to the fixed block 109, the force measuring push rod 113 is fixedly connected to the force measuring body 112, the force measuring body 112 is detachably connected to the mounting frame 111, and the mounting plate 106 is rotatably connected to the mounting plate 106. The mounting frame 111 is fixedly connected to the fixing block 109, the two fastening screws 116 are rotatably connected to the clamping plate 115, the clamping plate 115 is movably connected to the slider 114, the slider 114 is slidably connected to the slide rail 110, and the threaded rod 107 currently arranged rotates under the setting of the turntable 105, thereby driving the acupuncture needle and the clamping assembly 104 to move, and more accurate data can be obtained in the final test results. The design structure is simple, and solves the problem that it is inconvenient to control the moving distance during the manual pushing of the slider 114, and the final test result has low accuracy and large errors.

[0024] Among them, the clamping assembly 104 is located above the fixing seat 101, the dynamometer 102 is located above the fixing seat 101, the limit ring 108 is located at one end of the threaded rod 107, the turntable 105 is located at the other end of the threaded rod 107, the threaded rod 107 is located on one side of the mounting plate 106, and the mounting plate 106 is located on one side of the fixing seat 101. When the acupuncture needle needs to be tested for tightness, the acupuncture needle is first fixed, and then the turntable 105 is rotated. The rotation of the turntable 105 drives the rotation of the threaded rod 107, thereby driving the slider 114 to move forward or backward. Due to the setting of the limit ring 108, when the threaded rod 107 rotates, the slider 114 will keep synchronization with the movement of the limit ring 108, which facilitates the staff to move the slider 114. Since the distance of each movement is small, the accuracy of the final test result obtained is also more accurate.

[0025] Secondly, the slide rail 110 is located above the fixed block 109, the force measuring push rod 113 is located on one side of the force measuring body 112, the force measuring body 112 is located above the mounting frame 111, and the mounting frame 111 is located above the fixed block 109. The slide rail 110 provides a moving track for the slider 114 to facilitate the movement of the slider 114, driving the acupuncture needle to be tested to move toward the direction of the force measuring push rod 113. The force measuring body 112 can be removed from the mounting frame 111, which is convenient for the staff to observe and record the test data on the force measuring body 112.

[0026] At the same time, the two fastening screws 116 are both located above the clamping plate 115, and the clamping plate 115 is located above the slider 114, and the slider 114 is located above the slide rail 110. First, the needle body is placed above the slider 114, and the needle sleeve is moved away from the slider 114, the position of the slider 114 is adjusted, and the needle sleeve is abutted against the force measuring push rod 113, and then the two fastening screws 116 are rotated to clamp and fix the clamping plate 115 and the slider 114 to ensure that the needle body will not fall off or shake during the test. As the turntable 105 is rotated, the rotation of the turntable 105 drives the slider 114 to move on the slide rail 110, and the needle sleeve and the force measuring push rod 113 continuously apply pressure, and finally break at this moment, and stop the rotation of the turntable 105. At this time, the value displayed on the force measuring body 112 is the tightness value between the needle sleeve and the needle body.

[0027] In this embodiment, the threaded rod 107 is rotated under the setting of the turntable 105, thereby driving the acupuncture needle and the clamping assembly 104 to move, and more accurate data can be obtained in the final test result. The design structure is simple, and solves the problem that it is inconvenient to control the moving distance during the manual pushing of the slider 114, and the final test result has low accuracy and large errors. When the acupuncture needle needs to be tested for tightness, the acupuncture needle is first fixed, and then the turntable 105 is rotated. The rotation of the turntable 105 drives the rotation of the threaded rod 107, thereby driving the slider 114 to move forward or backward. Due to the setting of the limit ring 108, when the threaded rod 107 rotates, the slider 114 will keep synchronization with the movement of the limit ring 108, which facilitates the staff to move the slider 114. Since the distance of each movement is small, the accuracy of the final test result is also more accurate. The slide rail 110 provides movement for the slider 114 The track is convenient for the movement of the slider 114, driving the acupuncture needle to be tested to move toward the direction of the force measuring push rod 113. The force measuring body 112 can be removed from the mounting frame 111, which is convenient for the staff to observe and record the test data on the force measuring body 112. First, the needle body is placed above the slider 114, and the needle sleeve is separated from the slider 114. The position of the slider 114 is adjusted, and the needle sleeve is abutted against the force measuring push rod 113. Then, the two are rotated. The fastening screw 116 clamps and fixes the clamping plate 115 and the slider 114 to ensure that the needle body does not fall off or shake during the test. As the turntable 105 is rotated, the rotation of the turntable 105 drives the slider 114 to move on the slide rail 110, and the needle sleeve and the force measuring push rod 113 continuously apply pressure, and finally break at this moment, stopping the rotation of the turntable 105. At this time, the value displayed on the force measuring body 112 is the tightness value between the needle sleeve and the needle body.
