Further, because two adjacent sliding assemblies 130 are close to each other, when one sliding assembly 130 slides, it may drive the other sliding assembly 130 to move along with the sliding assembly, resulting in misoperation; therefore, to prevent erroneous operation due to the following of the glide assembly 130, the shift operating device 100 is further provided with an interlocking snap 150.
The housing 110 is provided therein with an interlock passage extending in a direction perpendicular to the slide passage 1124 and communicating with the slide passages 1124 at both ends. The clamping piece is slidably arranged in the interlocking channel. A clamping groove 1322 is formed in the side surface of the sliding plate 132; when the sliding assemblies 130 are located at the middle position, two ends of the interlocking clamping piece 150 respectively correspond to the clamping grooves 1322 of the two adjacent sliding plates 132, and when one of the two adjacent sliding plates 132 deviates from the middle position, the sliding plate 132 deviating from the middle position can push the interlocking clamping piece 150 into the clamping groove 1322 of the other sliding plate 132, so that the other sliding plate 132 is locked.
Specifically, the interlocking clip 150 is spherical, and the clip groove 1322 is a spherical groove; and the depth of the catching groove 1322 is smaller than the radius of the interlocking catching piece 150, so that when the sliding plate 132 slides by being pulled by the operating handle 120, the sliding plate 132 can push the interlocking catching piece 150 embedded in the catching groove 1322 into the interlocking passage. The interlocking channel is a cylindrical channel, and three interlocking clamping pieces 150 can be arranged in the interlocking channel; the sum of the gaps between the three interlocking snap members 150 is greater than 1 depth to less than 2 depths of the snap recesses 1322.
For example, if the radius of the three interlocking clips 150 is r, the depth of the clip recess 1322 is less than r; when the interlocking clips 150 at the two ends are respectively embedded into the corresponding clipping grooves 1322 and the middle interlocking clip 150 abuts against the interlocking clip 150 at the right end, then the gap between the interlocking clip 150 at the left end and the interlocking clip in the middle is smaller than r which is larger than r and smaller than 2 times. At this time, one of the interlocking snaps 150 at the left or right end can be pushed into the interlocking channel.
