Embodiment Two

This embodiment is another implementation of the present application. The difference between this implementation and the implementation of Embodiment One is that: the inner surface of the handle housing 2 is also provided with a second slot along its axial direction. The second slot is smaller than the depth of the first slot 9, and the depth of the second slot is smaller than the height of the first protrusion 6, that is, when the first protrusion 6 rotates to the second slot, the handle housing 2 will also lock the handle sleeve rod 3, but the locking force at this time is smaller than the locking force of the first protrusion 6 Clamping the inner wall of the handle housing 2, so that the first protrusion 6 has two locking positions with different locking forces, which can be adjusted according to the actual locking requirements. In addition, the number of second slots is also three, and the three second slots are respectively connected to the three first slots 9, so that the first protrusion 6 can feel the locking force at this time when it rotates from the first slot 9 to the second slot, and then consider whether to rotate the first protrusion 6 to the inner wall of the handle housing 2.

Embodiment Three

This embodiment is another implementation of the present application. The difference between this implementation and the implementation of Embodiment One is that: the handle further includes a handle middle shell, the handle middle shell is a hollow structure, the handle middle shell is located between the handle sleeve rod 3 and the handle outer shell 2, specifically, the handle middle shell is sleeved outside the handle sleeve rod 3, and the handle outer shell 2 is sleeved outside the handle middle shell, and both ends of the handle middle shell are provided with middle shell end covers, which are detachably connected to the handle middle shell by screws or buckles.

The outer surface of the handle middle shell is provided with a second protrusion along its axial direction, and the shape and size of the second protrusion are the same as those of the first slot 9. When the second protrusion is located in the first slot 9, the handle middle shell is connected with the handle outer shell 2 with a clearance fit, and when the second protrusion slides out of the first slot, the handle middle shell is tightly connected with the handle outer shell 2; the inner surface of the handle middle shell is provided with a third slot along its axial direction, and when the first protrusion 6 is located in the third slot, the handle middle shell is connected with the handle sleeve rod 3 with a clearance fit, and when the first protrusion 6 slides out of the third slot, the handle middle shell is tightly connected with the handle sleeve rod 3; the tight fit degree between the handle outer shell 2 and the handle hollow is greater than the tight fit degree between the handle middle shell and the handle sleeve rod 3; The inner walls of the shell and the handle housing 2 are often provided with limit strips. When the handle housing 2 is rotated, the handle middle shell rotates with the handle housing 2, that is, the handle middle shell and the handle housing 2 form a whole and rotate relative to the handle sleeve rod 3. The first protrusion 6 rotates to the third slot, and the handle housing 2 is slid up and down to make the handle middle shell and the handle housing 2 move up and down relative to the handle sleeve rod 3, which plays a role in preliminarily adjusting the handle length. At this time, the handle housing 2 continues to be rotated so that the handle sleeve rod is against the limit strip of the handle middle shell, and the handle middle shell no longer rotates relative to the handle sleeve rod 3. The handle housing 2 is rotated with greater force, and the handle housing 2 rotates relative to the handle middle shell, so that the second protrusion is located in the first slot 9, and the handle housing 2 is slid up and down to make the handle housing 2 move up and down relative to the handle middle shell and the handle sleeve rod 3, which plays a role in further adjusting the handle length.

Embodiment Four

Referring to FIGS. 5 and 6, this embodiment is another implementation of the present application. The difference between this implementation and the implementation of Embodiment One is that: the first protrusion 6 is in the shape of a rectangular protrusion, the first slot 9 is in the shape of a rectangular slot, and a limiting portion 33 is formed between the first slot 9 and the inner wall of the handle housing 2; when the first protrusion 6 is ready to rotate in the first slot 9, the limiting portion 33 will limit the outer wall of the first protrusion 6 to prevent the first protrusion 6 from accidentally sliding out of the first slot 9. Only by manually rotating the handle housing 2 can the first protrusion 6 slide out of the first slot 9.

This embodiment also provides the same second slot 32 as that in the second embodiment, and thus can be adjusted according to actual locking requirements.

The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features applied herein.
