[0033] At the same time, the second spring 107 in the stop assembly 10 drives the connecting rod 102 to move on the guide block 101 through the push cap 103, the connecting rod 102 drives the limiting block 9 to rotate through the linkage rod 105 and the sleeving column 106, so that the limiting block 9 maintains the limiting angle of the hand wheel 2, and the rotation of the hand wheel 2 is limited, which greatly reduces the probability of rotation caused by accidental contact of the hand with the hand wheel 2 when the operator is busy, eliminates the hidden danger of changing the running state of the device in the stationary state due to misoperation, and ensures the stable operation of the device.
[0034] When the hand wheel 2 needs to be adjusted, since the guide rod 61 is fixed between the frames 4, the operator pushes the limiting plate 5 away from the hand wheel 2, at this time, the sleeving block 62 slides on the guide rod 61, and the first spring 63 is compressed. With the movement of the limiting plate 5, the entire stop assembly 10 and the limiting block 9 connected therewith are driven away from the hand wheel 2, which avoids blocking the hand wheel 2 during adjustment of the hand wheel 2, provides space for adjustment of the hand wheel 2, and thus improves the efficiency of adjusting the hand wheel 2, and the operator can freely rotate the hand wheel 2 to the required position to make corresponding adjustment operation on the device.
[0035] The above specific embodiments are only optional embodiments of the present application, and based on the technical scheme of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
