The utility model discloses simple structure adopts slide switch 120 to replace rotary encoder, can effective reduce cost.

Referring to fig. 1, 4, 6, 8, and 9, for example, the connection part 132 may be configured as a first abutting part 132a and a second abutting part 132b extending in an axial direction from the rotation operation part 131. The first abutting portion 132a and the second abutting portion 132b are arranged at an interval in the circumferential direction of the rotation operation portion 131. An accommodation opening formed between the first abutting portion 132a and the second abutting portion 132b is for accommodating the slide operation portion 122. When the rotation operation portion 131 is turned, the first abutting portion 132a or the second abutting portion 132b may apply an abutting force to the slide operation portion 122, so that the slide operation portion 122 moves in the first direction. The abutting forces applied to the slide operation portion 122 by the first abutting portion 132a and the second abutting portion 132b are opposite.

Referring to fig. 1, 8 and 9, in addition, the handle housing 110 is opened with a mounting hole 111a, and the mounting hole 111a is used for mounting the knob 130. The knob 130 further includes a limit mounting part 133 between the rotation operating part 131 and the connecting part 132. The limit fitting part 133 includes a tubular part 133a and a catching protrusion 133b. The tubular portion 133a is fitted with the mounting hole 111 a. The catching projection 133b is provided to project radially to the outer circumferential surface of the tubular portion 133 a. One end of the catching projection 133b facing away from the rotation operating part 131 has a guide slope 133b1.
