Wherein the hand control mechanism 12 has a control rod 121 that passes through the side plate 111 transversely, the control rod 121 has a rotary control portion 122 located outside the side plate 111, and a control rod portion 123 extending into the chamber 112, And the hand control mechanism 12 also has a linkage piece 124, an induction piece 125, and two clasps 120 that are sleeved on the lever portion 123 in linkage, wherein the outer ring surface of the linkage piece 124 offers several etc. The interlocking concave portion 126 of the distance. Rotating the lever 121 by hand can drive the interlocking part 124 and the sensing part 125 to rotate together, so that a radially protruding sensing part 127 on the sensing part 125 corresponds to the photoelectric switch 15 or another photoelectric switch 16 .

The electric control mechanism 13 has a motor 131 , a worm wheel 132 installed on the output shaft of the motor 131 , and an engaging gear 133 meshed with the worm wheel 132 . The clutch mechanism 14 has: a positioning seat 141 fixed in the chamber 112, a clutch seat 142 that can rotate around the control rod 121 and meshes with the engaging gear 133, several positioning pins 143, and several positioning pins 143 shafts A spring 144 with elastic force, wherein the positioning seat 141 has an inner ring surface 145 arranged around a central axis, and several positioning recesses 146 arranged on the inner ring surface 145, the positioning tip 143 and the spring 144 are respectively It is installed in the number of mounting grooves 147 provided on the clutch seat 142, and each positioning pin 143 has a circular arc positioning end 148 away from the linkage 124, and a linkage positioning end 149 close to the linkage 124.

In the unlinked state, pushed by each spring 144, the circular arc positioning end 148 of the positioning pin 143 is positioned in each positioning recess 146 of the positioning seat 141, and the linkage pin 143 on the positioning pin 143 is located on the radial inner side.

However, in terms of manufacturing, the aforementioned The patent application has the deficiency that the electric control operation is not smooth. The reason for the aforementioned deficiency is that when the patent application is converted from the unlinked state to the linked state, the positioning pin 143 overcomes the elastic force of the spring 144 and moves radially inwardly relative to the linkage 124 to engage, while the positioning pin 143 moves radially inwardly relative to the linkage 124, mainly through the abutment between the circular arc positioning end 148 and the positioning recess 146 of the positioning seat 141, although this patent application is on each positioning recess 146 All are provided with oblique push surfaces, but because the arc positioning end 148 of the positioning pin 143 is a fixed and non-rotating design, when the power transmission clutch seat 142 of the motor 131 rotates, it is supported by the spring 144, and the circle The arc positioning end 148 and the positioning recess 146 are carried out in a manner of closely abutting against each other. At this time, when the arc of the arc positioning end 148 is more circular, the positioning pin 143 cannot move radially inward smoothly. Assuming the arc positioning When the arc of the end 148 is changed to a relatively straight shape, due to the insufficient engagement depth between the arc positioning end 148 and the positioning recess 146, it is easy to cause unreliable manual operation. This is what needs to be improved in the design of the previous patent. place.
