[0037] Furthermore, the edges a of the first rack 21 and the second rack 26 near the gear assembly are arc-shaped, so that the sliding paths of the first unit 1 and the second unit 2 are arc-shaped. The first rack 21 is located between the first portion 101 and the third portion 201, and the second rack 26 is located between the second portion 102 and the fourth portion 202, to prevent pinching of fingers when the gears and racks engage. In some embodiments, the first rack 21 is fixed to the third portion 201, and the second rack 26 can be fixed to the fourth portion 202.

[0038] In addition, in other preferred embodiments of the present invention, the curvature adjustment mechanism further includes a locking mechanism capable of locking the first unit 1 and the second unit 2. Specifically, the locking mechanism includes a fixing rod 28, a locking block 29, a cam handle 30, and a spring 31. One end of the fixing rod 28 is fixedly connected to the third portion 201.

The locking block 29 and the spring 31 are sleeved on the fixing rod 28. The spring 31 is disposed between the locking block 29 and the third portion 201. When the cam handle 30 is rotated, it pushes the locking block 29 into contact with the first portion 101. Due to the friction between the locking block 29 and the first portion 101, the first unit 1 and the second unit 2 are locked. To unlock, the cam handle 30 is rotated, and the locking block 29 is pushed away from the first portion 101 by the spring 31, thereby unlocking the first unit 1 and the second unit 2. In some embodiments, the locking mechanism further includes a locking bar 32, which is fixed to the first portion 101 and corresponds to the locking block 29. The surface of the locking bar 32 opposite the locking block 29 is provided with a first serration 3201; the surface of the locking block 29 opposite the locking bar 32 is provided with a second serration (not shown). When the first unit 1 and the second unit 2 are locked, the first serration 3201 cooperates with the second serration to better lock the first unit 1 and the second unit 2.

[0039] Furthermore, the elastic resisting assembly 50 includes a resisting ball 51 and a first elastic member 52. The first elastic member 52 drives the resisting ball 51 to resist the poking groove 2202. The end of the first elastic member 52 away from the resisting ball 51 can resist the handle 210. Specifically, the handle 210 can be provided with a receiving groove for accommodating the resisting ball 51 and the first elastic member 52. To facilitate installation and maintenance, in this embodiment, the elastic resisting assembly 5 also includes a supporting stud 53. The handle 210 is provided with a mounting hole (located at the bottom of the handle 210, not shown in the figure). The resisting ball 51, the first elastic member 52 and the supporting stud 53 are respectively arranged in the mounting hole. The two ends of the first elastic member 52 respectively resist the resisting ball 51 and the supporting stud 53. The first elastic member 52 can be optionally a spring or the like.
