For example, the first adjustment mechanism 201 and the second adjustment mechanism 202 may have substantially the same mechanism. The first adjustment mechanism 201 will be described as an example.
For example, in some examples of the present disclosure, as shown in fig. 2-3, the first adjustment mechanism 201 includes an adjustment base 2011 and an adjustment portion 2012, e.g., the adjustment base 2011 may be disposed on the first stationary base 203; the adjusting part 2012 may be disposed on a side of the adjusting base 2011 away from the first fixed seat 203, and configured to fix the first connection end 102.
For example, in some examples of the present disclosure, as shown in fig. 3-4, the adjustment portion 2012 includes an adjustment knob 2013 configured to allow the tensioning portion 101, e.g., a tensioning cord, to be wound around the adjustment knob 2013 to adjust the degree of tension of the tensioning portion 101. For example, the adjustment knob 2013 may be rotated relative to the adjustment base 2011 such that the tension cord is wrapped around the adjustment knob 2013.
For example, in some examples of the present disclosure, as shown in fig. 3-4, the adjusting knob 2013 of the first adjusting mechanism 201 includes a protruding shaft 2021, for example, the first connecting end 102 of the tensioning portion 101 may be formed in a ring shape, so as to be sleeved on the protruding shaft 2021 of the first adjusting mechanism 201 and tightly wound and fixed on the adjusting knob 2013 by the rotation of the adjusting knob 2013; similarly, the adjusting knob of the second adjusting mechanism 202 may also include a protruding shaft 2021, and the second connecting end 103 of the tensioning portion 101 may be formed into a ring shape, so as to be sleeved on the protruding shaft 2021 of the second adjusting mechanism 202 and tightly wound and fixed on the adjusting knob 2013 by the rotation of the adjusting knob 2013. The tensioning part 101 is locked by at least one of the first adjusting mechanism 201 and the second adjusting mechanism 202, so that the electrode needle a fixed on the tensioning part can be pressed tightly.
For example, in some examples of the present disclosure, the connection manner of the adjusting part 2012 and the tensioning part 101 may also be adjusted as appropriate according to the actual situation, for example, the structure of the adjusting knob 2013 may be changed to a through hole type, and at this time, the tensioning part may be fixed in a through hole type; embodiments of the present disclosure are not limited in this regard.
For example, in some examples of the present disclosure, as shown in fig. 3, the adjusting part 2012 may further include a gear 2014 and a reset switch 2015, the gear 2014 is disposed on an adjusting base 2011, and the adjusting knob 2013 is connected, e.g., fixedly connected, to the gear 2014 and may drive the gear 2014 to rotate; reset switch 2015 is configured to interfere with or release gear 2014 to limit or reset gear 2014.
For example, in some examples of the present disclosure, as shown in fig. 3, the adjuster 2012 further includes a reset switch fixing block 2016, an elastic connector 2017, and a fixing shaft 2018. The reset switch fixing block 2016 is fixedly connected to the adjusting base 2011, and may be fixed by bolts, for example; the middle part of reset switch 2015 is connected with reset switch fixed block 2016 through fixed axle 2018 to reset switch 2015 can use fixed axle 2018 to rotate as the axle, and first end 20161 of reset switch 2015 is connected with reset switch fixed block 2016 through flexible connector 2017, and first end 20161 is configured to contradict or loosen gear 2014. For example, the resilient connectors 2017 may be springs or the like.
For example, in some examples of the present disclosure, as shown in fig. 3 and 5, the reset switch 2015 may be rotated around the fixing shaft 2018, when the gear 2014 is rotated in the clockwise direction, a process of locking the tensioning portion 101 by the adjusting knob 2013 by the tensioning portion 101 is shown, at this time, each tooth of the gear 2014 may be interfered by the first end 20161 after passing through the first end 20161 of the reset switch 2015 to limit the reverse rotation of the gear 2014, so that the tensioning state of the tensioning portion 101 may be maintained; after the operation requirement is met, for example, after the tensioning part 101 is adjusted to the required tensioning state, the reset switch 2015 is rotated around the fixing shaft 2018 in the counterclockwise direction, so that the elastic connecting piece 2017, for example, a spring, is pressed by the reset switch 2015, a space for the gear 2014 to rotate in the counterclockwise direction is reserved, and therefore, one-key reset is realized, and the tensioning part 101 is changed from the locking state to the loosening state.
For example, in some examples of the present disclosure, as shown in fig. 3, an adjusting cover 2019 may be further disposed on the adjusting base 2011, and the adjusting cover 2019 shields and covers components of the adjusting portion 2012 except for the adjusting knob 2013, so as to achieve a beautifying effect; meanwhile, a plurality of operating components are not directly exposed outside, and the maintenance of the components and the damage prevention are facilitated.
For example, in some examples of the present disclosure, as shown in fig. 3, an operation rod 2020 may be further disposed on the reset switch 2015, and the gear 2014 may be reset directly by shifting the operation rod 2020, so as to improve convenience of operation.
For example, in some examples of the present disclosure, when the adjustment cover 2019 is provided, since the reset switch 2015 is covered, an opening structure may be added to the adjustment cover 2019 to extend the operating rod 2020 on the reset switch 2015 out of the adjustment cover 2019; for example, the trend of the opening structure can be designed according to the rotation direction of the reset switch 2015, so that a movement space is provided for the operating rod 2020.
For example, in some examples of the present disclosure, for example, the second adjustment mechanism 202 is substantially identical in structure to the first adjustment mechanism 201, and for example, the first fixing base 203 is also substantially identical in structure to the second fixing base 204. By designing the same structure, the operation can be simplified and the development cost of the adjustment structure can be reduced.

Through the chute 2031 and the first adjusting mechanism 201, the operation position of the electrode needle can be moved as required during operation, thereby enhancing the convenience of operation.
For example, in some examples of the present disclosure, as shown in fig. 6, the number of the adjustment parts 2012 placed in the chute 2031 may be plural, 2 being shown as an example in the figure; for example, when more or fewer operation electrode needles are required, the number of the adjustment parts 2012 can be adjusted according to the requirement, which is not limited by the present disclosure.
For example, in some examples of the present disclosure, as shown in fig. 7, the chute 2031 may include a plurality of sinking holes 2032, for example, the plurality of sinking holes 2032 are disposed on a bottom surface of the chute 2031 and are arranged at intervals along an extending direction of the chute 2031. The adjustment base 2011 further includes a sliding portion 2033, the sliding portion 2033 protrudes from a side of the adjustment base 2011 away from the adjustment portion 2012, i.e., a lower side in the drawing, for example, the sliding portion 2033 may be disposed in the adjustment base 2011 and protrudes from a bottom surface. The sliding portion 2033 is configured to be recessed into the depressed hole 2032 during the sliding of the adjustment base 2011 in the chute 2031, and to be removed from the depressed hole 2032 when an external force is applied. Therefore, in the process of operating a plurality of electrode needles simultaneously, the position of the adjusting base 2011 on the sliding groove 2031 can be changed according to the distance requirement between the electrode needles, and the sliding portion 2033 is fixed by the lower counterbore 2032.
For example, in some examples of the present disclosure, as shown in fig. 8, the adjusting base 2011 may further include a plunger 2036 and a plunger spring 2035, for example, the plunger spring 2035 is disposed in the hollow cavity of the plunger 2036, and one end of the plunger spring 2035 is connected to the sliding portion 2033 and is configured to be pushed against the sliding portion 2033 in a direction away from the adjusting portion 2012, so that the sliding portion 2033 protrudes out of a side of the adjusting base 2011 away from the adjusting portion 2012. For example, the sliding portion 2033 may be designed to be spherical, so that when the adjustment portion 2012 moves, the sliding portion 2033 may roll along with the elastic force of the plunger spring 2035; for example, the opening diameter of the plug 2036 is smaller than the diameter of the sliding portion 2033, thereby ensuring that the sliding portion 2033 does not become disengaged from the plug 2036.
It should be noted that the spacing between the lower counterbores 2032 can be designed according to the density of the desired fixing positions of the electrode needles, which is not limited by the present disclosure.
