Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 3 The utility model provides the following technical solutions: an adjustable gear shifting seat for a knife sharpener, comprising a driving frame 1, a gear shifting rod body 2, a gear shifting pin 3 fixed to the end of the gear shifting rod body 2 and a mounting assembly 4, the gear shifting rod body 2 is fixed to the driving frame 1 by the mounting assembly 4, and the mounting assembly 4 comprises: a positioning seat 41, a positioning boss 411 and a hand-tightening knob 42.

[0032] Specifically, by Figure 1 and Figure 2 As shown, in this embodiment, the positioning seat 41 is fixed on the driving frame 1, the positioning boss 411 is fixed on the top of the positioning seat 41 and embedded in the gear lever body 2, and the positioning boss 411 has a threaded hole 4111, and a threaded column 421 is fixed on the hand-tightening knob 42 and screwed into the threaded hole 4111 through a threaded screwing method. Therefore, when in use, the positioning seat 41 is first fixed on the driving frame 1, and then the gear lever body 2 is placed on the positioning seat 41, so that the positioning boss 411 is embedded in the gear lever body 2, The gear lever body 2 is positioned and restricted at the same time to prevent the gear lever body 2 from rotating relative to the driving frame 1. Then, the threaded column 421 is screwed into the threaded hole 4111, and the gear lever body 2 is squeezed by the hand-tightening knob 42 and the positioning seat 41, and the positioning and limiting are performed by the positioning boss 411, which can ensure the stability of the installation of the gear lever body 2 and prevent the gear lever body 2 from shaking and rotating during operation. At the same time, the position of the gear lever body 2 can also be adjusted to meet different usage needs.

[0033] It should be noted that, in order to achieve better positioning requirements, the length of the positioning boss 411 is equal to the slot width of the gear lever body 2 , that is, the end surface of the positioning boss 411 abuts against the inner wall of the gear lever body 2 to prevent the gear lever body 2 from rotating relative to the driving frame 1 .

[0034] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, it also includes: a fixing flange 412, the fixing flange 412 is fixed to the bottom end of the positioning seat 41, the positioning seat 41 is fixed to the driving frame 1 by means of the fixing flange 412, and the fixing flange 412 is fixed to the driving frame 1 by bolts, so that the positioning seat 41 can be stably installed.

The two anti-skid rubber pads 43 are respectively mounted on the positioning boss 411 and the threaded column 421. After tightening the hand-tightening knob 42, the two anti-skid rubber pads 43 shrink to increase the friction force, further improving the installation stability of the gear lever body 2. At the same time, the anti-skid rubber pad 43 is also flexible, which prevents the hand-tightening knob 42 and the positioning seat 41 from rigidly squeezing the gear lever body 2 to cause mechanical damage to the gear lever body 2, thereby improving the safety of the gear lever body 2.

[0037] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, both the top and bottom surfaces of the anti-skid rubber pad 43 are provided with anti-skid protrusions 431 , which have a good anti-skid effect, improve the installation stability of the gear shift lever body 2 , and prevent the gear shift lever body 2 from sliding during operation.

[0038] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the circumferential surface of the hand-tightening knob 42 is provided with anti-skid convex patterns 422 to increase the friction between the hand and the hand-tightening knob 42 and improve the stability of rotating the hand-tightening knob 42 .

[0039] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, two shifting pins 3 are spaced apart and detachably mounted on the end of the gear shifting rod body 2 . The double shifting pin 3 design has high structural strength and is safer to use.

[0040] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, it also includes: a limit plate 5 and a locking bolt 6. Two symmetrically distributed internal threaded tubes 51 are fixed on the limit plate 5. The end of the gear lever body 2 is clamped on the inner side of the two shifting pins 3, and a No. 1 positioning hole 21 is opened on the gear lever body 2, and a No. 2 positioning hole 31 is opened on the shifting pin 3. The internal threaded tube 51 passes through the No. 2 positioning hole 31 and the No. 1 positioning hole 21. The locking bolt 6 is screwed into the internal threaded tube 51 by threaded engagement. The two shifting pins 3 are respectively placed on the upper and lower parts of the gear lever body 2, and the No. 2 positioning hole 31 corresponds to the No. 1 positioning hole 21. Then, the internal threaded tube 51 passes through the No. 2 positioning hole 31 and the No. 1 positioning hole 21, and the locking bolt 6 is screwed into the internal threaded tube 51. The stable installation of the two shifting pins 3 can be achieved, and it is also convenient to disassemble and replace the damaged shifting pin 3.
