Example 1:

as shown in fig. 1-5, an excavator control box comprises an upper shell 1, a lower shell 3, a rotating frame 6, a fixed frame 12, a cam mechanism 13 and a handle 4, the upper shell 1 is connected with the lower shell 3 and then installed on the rotating frame 6, the lower side of the fixed frame 12 is connected with the rotating frame 6 through a shaft I15, the shaft I15 is fixed with the rotating frame 6 through a shaft sleeve and a bolt 7, the shaft I15 serves as the rotating center of the rotating frame 6, the cam mechanism 13 is connected with the rotating frame 6 through a shaft II 16, the shaft II 16 is fixedly connected with the handle 4, when the handle 4 is pressed, the cam mechanism 13 rotates along with the shaft, and the handle 4 is installed above the rotating frame 6. The shaft II 16 is connected with the cam mechanism 13 in a welding mode, the shaft II 16 penetrates through a control box framework of the rotating frame 6 to be sleeved on a shaft sleeve of the handle 4, and finally the shaft II is connected with the shaft sleeve through the expansion pin 5.

Example 2:

a sleeve 14 is arranged on a fixed frame 12, a track groove 18 is further formed in a cam mechanism 13, and the sleeve 14 is installed in the track groove 18. Namely, the entrance of the track groove 18 is tangent to the sleeve 14, the pin 19 is installed on the fixed frame 12, the sleeve 14 is installed on the pin 19, the handle 4 is pressed down to drive the cam mechanism 13 to move, so that the sleeve 14 moves along the track groove 18 of the cam mechanism 13, the running track of the cam mechanism 13 is limited by the sleeve 14, and the sleeve 14 has the following functions: the sliding between the cam mechanism 13 and the fixed frame 12 is changed into rolling, the service life is prolonged, and the track groove 18 on the cam mechanism 13 is prevented from being deformed or abraded due to long-term sliding.
