Further, the first end of the first rocker arm is provided with a U-shaped connecting portion, the connecting portion comprises a first connecting plate, a second connecting plate and a third connecting plate, the second connecting plate and the third connecting plate are located at two ends of the first connecting plate, opposite through holes are formed in the third connecting plate and the second connecting plate, and the pin shaft is arranged in the through holes.
Further, the length of the first connecting plate is the same as the length of the pin sleeve.
Further, the second connecting plate and the third connecting plate are equal in length and larger than the outer caliber of the pin shaft sleeve.
From the above, the linkage control lever provided by the invention has the following advantages compared with the prior art: the pin shaft and the rotating shaft which are perpendicular to each other can enable the operating handle to have four operating directions, namely two operating directions along the pin shaft and two directions along the rotating shaft, so that the operating handle is convenient to operate. Secondly, the U-shaped connecting part can enable the pin shaft to be connected more firmly.

Detailed Description
The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent. Wherein like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The words "inner" and "outer" are used to refer to directions toward or away from, respectively, the geometric center of a particular component.
As shown in fig. 1 and 2, a linkage control rod comprises a connecting rod 1, one end of the connecting rod 1 is provided with a handle 2, the other end of the connecting rod is provided with a pin shaft sleeve 3, a first end of a first rocker arm 401 of a rocker arm body 4 is rotationally connected to the pin shaft sleeve 3 through a pin shaft 5, the rocker arm body 4 further comprises a second rocker arm 402 which is positioned at a second end of the first rocker arm 401 and integrally arranged with the first rocker arm 401, the first rocker arm 401 and the second rocker arm 402 are mutually perpendicular, a rotating shaft 6 is arranged at a second end of the first rocker arm 401, the rocker arm body 4 can rotate around the rotating shaft 6, the rotating shaft 6 is perpendicular to the pin shaft 5, one end of the second rocker arm 402, which is far away from the first rocker arm 401, is hinged with one end of a right-hand pull rod 7, and the other end of the right-hand pull rod 7 is left-hand pull rod 9 through a double-hand nut 8.
The first end of the first rocker arm 401 is provided with a U-shaped connecting portion 10, the connecting portion 10 comprises a first connecting plate 1001, a second connecting plate 1002 and a third connecting plate 1003, the second connecting plate 1002 and the third connecting plate 1003 are positioned at two ends of the first connecting plate 1001, opposite through holes 1004 are formed in the third connecting plate 1003 and the second connecting plate 1002, and the pin shaft 5 is arranged in the through holes 1004.
