In this embodiment, the rotation relationship between the control plate 2 and the housing 1 is configured as hole axis fit, and the specific structure is: the control board 2 is fixedly provided with a first rotating shaft A, the shell 1 is provided with a shaft hole for accommodating the first rotating shaft A, and the control board 2 is rotatably arranged on the shell 1 through the matching of the first rotating shaft A and the shaft hole. Based on this rotational fit relationship, it should be understood that the hole-shaft fit may also be interchanged, such as providing a shaft hole in the handle plate 2 and providing the first rotation axis a in the housing 1.
In this embodiment, the housing 1 has a slot to accommodate the follower groove 21 of the control plate 2, where the slot satisfies the sliding stroke of the follower groove 21 and provides a limit for the follower groove, the follower groove 21 includes a first clamping arm 21a and a second clamping arm 21b with the same structure, vertically opposite each other and parallel axes, and a slot for penetrating the connecting rod 4 is reserved between the two clamping arms, and in this embodiment, the cross sections of the first clamping arm 21a and the second clamping arm 21b are all triangular to adapt to the structure and the movement track of the connecting rod 4.
The indicator 3 is slidably mounted in the chute 11 of the housing 1, the upper end is an indication end, the lower end is provided with a protruding portion 32, the end portion of the protruding portion 32 is provided with a long groove 31, and the long groove 31 is used for penetrating and connecting one end of the connecting rod 4. The outer part Zhou Yongyi of the projection 32 is sleeved with an indicator spring 5.
