DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be further specifically described below with reference to the embodiments and the accompanying drawings.

[0018] Example: A skin muscle tension measuring device of this embodiment is used to quantitatively detect the degree of edema of the skin muscle lymph nodes of the human limbs, such as Figure 1 、 Figure 2 and Figure 3As shown, the measuring device includes a circular cylindrical body 1, a cavity 11 with an opening on the bottom surface of the cylindrical body is designed, a slider 2 is embedded in the cavity that matches the cross-section of the cavity and slides along the cavity, a spring 3 is embedded between the top surface of the slider and the top surface of the cavity, and a measuring disc 4 is designed on the bottom surface of the slider that is rigidly connected to the slider and located outside the cavity opening. The bottom surface of the measuring disc fits the measuring area of the human skin. A transparent display window 12 is provided on the side of the cylindrical body, and a scale line 13 is designed on the display window. The side of the slider corresponding to the display window is designed with a scale line 13. Identification line 21, the above identification line can be seen through the display window; a positioning groove is designed on one side of the cavity, and a positioning strip 22 corresponding to the positioning groove is designed on the side of the slider and embedded in the positioning groove. The slider moves up and down along the cavity through the cooperation of the positioning strip and the positioning groove. The other side surface of the slider corresponding to the positioning strip is provided with a rack 23 distributed up and down, and a groove 14 is provided on the side wall of the cavity corresponding to the above rack. A backstop device 5 is installed in the above groove, and the backstop device includes a backstop shaft 51, a backstop card 52, a backstop spring 53 and a complex The positioning rod 54, the above-mentioned anti-retraction shaft is installed in the groove, the middle part of the anti-retraction card is sleeved on the anti-retraction shaft and rotates with the anti-retraction shaft as the rotating shaft, the upper end of the anti-retraction card is inserted into the tooth groove of the above-mentioned rack and abuts against the tooth groove, the inner side of the lower end of the anti-retraction card is connected with the anti-retraction spring, and the compressed anti-retraction spring pushes the lower end of the anti-retraction card outward, the above-mentioned reset rod passes through the side wall of the columnar body, its outer end is located outside the columnar body, and its inner end abuts against the lower end of the anti-retraction card, and the reset rod can overcome the elastic force of the anti-retraction spring and squeeze the lower end of the anti-retraction card inward; the outer edge of the bottom surface of the columnar body is opposite to the It is said that a supporting foot 6 is installed, and the inner end of the supporting foot is designed with a hinge 7 fixed to the outer edge of the bottom surface of the columnar body and rotates through the hinge point. The hinge is a self-resetting torque hinge. The outer end of the supporting foot rests on the skin surface and supports the columnar body. A positioning rod 8 is designed at the inner end of the supporting foot and is fixed to the supporting foot and along the axis of the supporting foot. The top of the columnar body is designed with a top cap 15 that is an integral structure with the columnar body.

Press the top cap to move the columnar body downward. The supporting feet are forced to rotate along the hinge points at their inner ends and slowly become horizontal. The front ends of the positioning rods on the two supporting feet slowly approach each other. When the front ends of the positioning rods are aligned with each other and form a straight line, it indicates that the supporting feet are horizontal. At this time, the measuring disc, which is subjected to the reaction force of the skin, pushes the slider to move upward along the cavity. When the slider moves upward, the upper end of the retaining clip The end of the slider is pushed down and retracted by the inclined surface of the teeth of the rack, causing the slider to move up tooth by tooth. When the measurement is completed and the slider is separated from the skin, the force on the measuring disc disappears and the slider falls. At this time, the upper end of the anti-retraction clamp is inserted into the tooth groove of the rack under the extrusion of the anti-retraction spring and is stuck in the tooth groove, preventing the slider from falling and completing the fixation of the current position of the slider. At this time, observe and record the position of the marking line on the surface of the slider of the measuring instrument on the scale line on the display window surface, and you can get the measured value of the skin muscle surface tension, which can quantitatively detect the degree of skin muscle hardening caused by lymph node enlargement.
