The description of the related directions in the utility model can be referred to.

[0054] The handle body 1 comprises a first shell 11 and a second shell 12 connected with each other, so that the driving part 3 is installed therein, and the first shell 11 is arranged at the upper end of the second shell 12. Specifically, in combination with Figure 2 , Figure 3 and Figure 8As shown, the driving component 3 comprises a driving gear 31 and a driven gear 32 which are engaged with each other, and a driving hand wheel 33, the driving gear 31 and the driven gear 32 are both rotatably arranged in the handle main body 1; one end of the driving hand wheel 33 is connected with the driving gear 31, and the other end is located outside the handle main body 1, and an operator can drive the driving gear 31 to rotate by rotating the driving hand wheel 33, and then drive the driven gear 32 to rotate. The locking structure 4 is arranged on one side of the driving gear 31 and / or the driven gear 32, and when in the locked state, the locking portion 42 can abut against the driving gear 31 and / or the driven gear 32, and the rotation of the driving gear 31 and / or the driven gear 32 is limited by the locking portion 42, so as to limit the position of the front end portion 2, so that the locking is more reliable.

[0055] In an embodiment, the front end portion 2 is connected with the driven gear 32, and the angle of the front end portion 2 is adjusted by the rotation of the driven gear 32. Preferably, when in the locked state, the locking portion 42 is pressed on the driven gear 32 to limit the rotation of the driven gear 32, so as to better limit the movement of the front end portion 2 to lock the front end portion 2.

[0056] It can be understood that there are many ways to limit the rotation of the driven gear 32. For example, the locking portion 42 can be clamped in the gear teeth of the driven gear 32 to limit the rotation of the driven gear 32; or the rotation of the driven gear 32 is limited by limiting the rotation of the rotation shaft of the driven gear 32.

[0057] Preferably, in combination with Figure 6 and Figure 7 As shown, when in the locked state, the locking portion 42 is pressed on one end of the driven gear 32 in the axial direction, and the other end of the driven gear 32 is pressed against the inner side wall of the handle main body 1, and the driven gear 32 is clamped and fixed by the locking portion 42 and the handle main body 1 which are pressed on both ends of the driven gear 32 in the axial direction, so that the locking effect is better, and the gear end surface of the driven gear 32 is contacted, without damaging the gear teeth and the rotation shaft of the driven gear 32, so as to better protect the driven gear 32.

[0058] In combination with Figure 3 , Figure 5 and Figure 10 As shown, the locking portion 42 comprises a locking column 421 which is rotatably arranged on the handle main body 1, and a locking protrusion 422 which is protrudingly arranged on one side of the locking column 421, and the adjusting portion 41 is arranged at one end of the locking column 421 and located outside the handle main body 1; when the adjusting portion 41 is rotated under the action of an external force to switch from the unlocked state to the locked state, the locking protrusion 422 can be pressed on the driving gear 31. Further, in combination with Figures 4 to 7As shown, the operator drives the locking column 421 to rotate by manually rotating the adjusting part 41, and drives the locking convex part 422 to rotate along the circumference of the locking column 421. The axial direction of the locking column 421 is parallel to the end face of the driven gear 32 and is spaced apart from the driven gear 32. The locking convex part 422 is protruded on one side of the locking column 421. When the locking convex part 422 rotates to the space between the locking column 421 and the driven gear 32, the locking convex part 422 is in contact with the driven gear 32 and abuts against the driven gear 32, which drives the other end of the driven gear 32 to directly or indirectly press on the handle body 1, thereby limiting the rotation of the driven gear 32 to lock the position of the front end part 2.

[0059] Further, the locking column 421 is substantially cylindrical, and the length of the locking convex part 422 in the axial direction of the locking column 421 is greater than or equal to the diameter of the driven gear 32, so that the pressing force of the locking convex part 422 on the driven gear 32 is more balanced, and the locking effect is better.

The rotating direction of the adjusting knob 411 is not specifically limited, and can be specifically set according to the habit of using hands, so that the locking convex part 422 is parallel to the end surface of the driven gear 32 when in the unlocked state, and the locking convex part 422 is pressed on the end surface of the driven gear 32 when in the locked state.

[0062] In an embodiment, the locking convex part 422 can be provided with two, and the two locking convex parts 422 are symmetrically arranged on the two sides of the radial direction of the locking post 421. So that the user can lock no matter whether the adjusting knob 411 is rotated forward or backward, and can better adapt to the operation habits of different operators.

[0063] Further preferably, the outer circumferential side of the adjusting knob 411 is arc-shaped, which is more smooth when contacted by the hands of an operator, and the bending direction of the adjusting knob 411 can follow the rotating direction, so that the ergonomic setting mode when adjusting the adjusting knob 411 is more in line with the human body, so that the hand feeling is better and the adjustment is more labor-saving.

[0064] Preferably, the adjusting knob 411 and the driving hand wheel 33 are respectively located on the adjacent two sides of the handle main body 1, and the rotating shaft of the adjusting knob 411 is perpendicular to the rotating shaft of the driving hand wheel 33.
