The fixing set 121 has a plurality of fixing parts 1211 and a ring part 1212. The plurality of fixing parts 1211 are arranged at intervals under the ring part 1212. The ring part 1212 and a plurality of fixing members 1211 form a perforation 1210. The inner diameter width W of the perforation 1210 gradually shrinks from the ring member 1212 to the plurality of fixing members 1211 (that is, the inner diameter width gradually decreases from large to small). One end of the debugging rod 122 comes from the ring member. 1212 is inserted into the through hole 1210, and the peripheral side of the debugging rod 122 is tightly fixed by a plurality of fixing members 1211.

Furthermore, the fixing part 111 further includes a second fixing groove 1112, and the first fixing groove 1111 is located at the bottom of the second fixing groove 1112, so that the first fixing groove 1111 and the second fixing groove 1112 form a stepped groove, that is, the first fixing groove 1111 is located at the bottom of the second fixing groove 1112. The groove bottoms of the two fixing grooves 1112 have an opening of the first fixing groove 1111 in the middle. In other words, the groove bottom of the second fixing groove 1112 is a plane on the peripheral side of the opening of the first fixing groove 1111 .

When the fixing set 121 is assembled in the first fixing groove 1111 and the second fixing groove 1112 of the fixing part 111, the outer side of the ring 1212 of the fixing set 121 is received and fixed in the second fixing groove 1112, and the plurality of fixing parts of the fixing set 121 are fixed in the second fixing groove 1112.

The ring member 1212 of the fixing set 121 has a ring opening 12120, and a plurality of fixing members 1211 are arranged at intervals along the edge of the ring opening 12120, so that the plurality of fixing members 1211 of the fixing set 121 are bendable relative to the ring member 1212. Among them, the number of fixing parts 1211 of the fixing set 121 in this embodiment is four (please refer to FIG. 5 ). The fixing kit 121 of this embodiment does not limit the number of fixing parts 1211. It is enough to have at least two fixing parts 1211, so that the fixing set 121 can closely fix the debugging head 1221 of the debugging rod 122 through the plurality of fixing parts 1211.

In addition, the diameter of the ring opening 12120 of the ring member 1212 is the same as or larger than the outer diameter D of the debugging head of the debugging rod 122 . The ring member 1212 further includes a guide edge 12121, and the guide edge 12121 is located around the ring opening 12120. The guide edge 12121 is a hypotenuse corresponding to the ring opening 12120, and the guide edge 12121 helps guide the debugging rod portion 1222 of the debugging rod 122 to be inserted toward the ring opening 12120 of the ring member 1212. The outer diameter of the debugging head 1221 of the debugging rod 122 is larger than the outer diameter of the debugging rod portion 1222 of the debugging rod 122 . The debugging rod portion 1222 of the debugging rod 122 first passes through the through hole 1210 of the fixing set 121 . The first inner diameter width corresponding to the through holes 1210 within the ring member 1212 is W1 and the second inner diameter width corresponding to the through holes 1210 within the plurality of fixing members 1211 is W2.

In this embodiment, the debugging rod portion 1222 of the debugging rod 122 is not limited by the inner diameter of the through hole 1210 of the fixing set 121 and can directly pass through. The debugging head 1221 of the debugging rod 122 can just pass through the hole 1210 corresponding to the range of the ring 1212. When the debugging head 1221 of the debugging rod 122 passes through the plurality of fixing members 1211, the debugging head 1221 is affected by the plurality of fixing members 1211. The inner abutment limit, that is, because the outer diameter D of the debugging head 1221 of the debugging rod 122 is greater than or equal to the second inner diameter width W2 corresponding to the through holes 1210 within the range of a plurality of fixing parts 1211, the debugging head 1221 of the debugging rod 122 The plurality of fixing members 1211 need to be stretched outward and deformed. At the same time, the debugging head 1221 of the debugging rod 122 will also be retracted and pressed inward by the reaction force of the plurality of fixing members 1211. While maintaining the retracted position of the plurality of fixing parts 1211 and pressingly fixing the debugging head 1221 of the debugging rod 122, the debugging rod part 1222 of the debugging rod 122 is inserted into the fixing hole 1110 of the first fixing groove 1111, so that the plurality of fixing parts 1211 The height position of the debugging head 1221 of the debugging rod 122 can be maintained by friction. In other words, the debugging head 1221 of the debugging rod 122 will not be affected by the weight or structural problems of the debugging rod 122 when it is not affected by external forces. Cause loosening and displacement. When the user needs to adjust the height position of the debugging rod 122 relative to the cover 11 , the user can directly adjust the debugging rod 122 in the fixing set 121 as long as the force exerted by the user is greater than the static friction force of the plurality of fixing members 1211 on the debugging rod 122 Move up and down.

In addition, please refer to Figure 2 again. When the debugging rod 122 is adjusted to the position of the fixing kit 121, since the fixing kit 121 and the debugging rod 122 are tightly fixed through the contact surface, the up and down movement of the debugging rod 122 will cause the fixing kit 121 and the debugging rod 122 to move up and down. The fixed contact surfaces between the debugging rods 122 generate friction, thereby generating friction debris or metal wires. The above debris or metal wires will fall into the first fixing groove 1111 located below the fixing set 121, and the first fixing groove 1111 The fixing hole 1110 is just blocked by the debugging rod portion 1222 of the debugging rod 122 . This can avoid the problem of friction debris or metal wires falling into the inside of the cover plate 11 due to adjusting the height of the debugging rod 122 .

Please refer to FIG. 6 , which is a cross-sectional view of the debugging structure of the second embodiment of the present application.

In some embodiments, the second thread 1223 has the same diameter in the axial direction of the debugging rod 122; or, the second thread 1223 has no taper in the axial direction of the debugging rod 122, and the fixing set 121 coincides with the axis of the debugging rod 122. . As the second thread 1223 screws into the first thread 1213, the plurality of fixing members 1211 are gradually stretched to produce elastic deformation. The elastic restoring force of the plurality of fixing members 1211 is exerted on the debugging head 1221 to cause the debugging rod 122 to Fixed by urgency. The fixing kit 121 of this embodiment is tightly fixed with a plurality of fixing parts 1211 through a threaded structure, which can better adjust and fix the height position of the debugging rod 122 relative to the cover plate 11 . In addition, the threaded structure between the debugging rod 122 and the fixing set 121 in this embodiment will more easily generate debris or wires due to friction. This embodiment can further utilize the groove bottom of the first fixing groove 1111 in the aforementioned embodiment. Friction debris or wire is beneficial to the use of debugging structure 1.
