当调节件420的数量为一个且需要改变上述调节件420与支撑件410的连接位置时，可使调节件420的第一定位孔422与支撑件410上当前位置的第一定位柱411相分离，从而将调节件420从支撑件410上拆离下来，然后将调节件420调节至需要的位置，最后再将调节件420的第一定位孔422与支撑件410上另一位置的第一定位柱411相配合，即可实现调节件420与支撑件410的连接位置沿推杆200的轴向调节并相对支撑件410的安装固定，进而实现第二行程开关600与支撑件410的连接位置沿推杆200的轴向可调并相对支撑件410的安装固定。 When the number of the adjusting member 420 is one and the connecting position of the adjusting member 420 and the supporting member 410 needs to be changed, the first positioning hole 422 of the adjusting member 420 can be separated from the first positioning column 411 of the current position on the supporting member 410 , So that the adjusting member 420 is detached from the supporting member 410, and then the adjusting member 420 is adjusted to a desired position, and finally the first positioning hole 422 of the adjusting member 420 and the first positioning of another position on the supporting member 410 When the post 411 cooperates, the connecting position of the adjusting member 420 and the supporting member 410 can be adjusted along the axial direction of the push rod 200 and fixed relative to the supporting member 410, thereby achieving the connecting position of the second travel switch 600 and the supporting member 410. The axial direction of the push rod 200 is adjustable and fixed relative to the installation of the support 410.
类似地，当调节件420的数量为两个且需要同时改变上述两个调节件420与支撑件410的连接位置时，可使两个调节件420的第一定位孔422分别与支撑件410上当前位置各自对应的第一定位柱411相分离，从而将两个调节件420从支撑件410上拆离下来，然后将两个调节件420分别调节至需要的位置，最后再将两个调节件420的第一定位孔422分别与支撑件410上另一位置各自对应的第一定位柱411相配合，即可实现两个调节件420分别与支撑件410的连接位置沿推杆200的轴向调节并相对支撑件410的安装固定，进而实现第一行程开关500和第二行程开关600与支撑件410的连接位置沿推杆200的轴向可调并相对支撑件410的安装固定。 Similarly, when the number of the adjusting members 420 is two and the connection positions of the two adjusting members 420 and the supporting member 410 need to be changed at the same time, the first positioning holes 422 of the two adjusting members 420 and the supporting member 410 can be respectively made The first positioning posts 411 corresponding to the current position are separated, so that the two adjusting members 420 are detached from the support member 410, and then the two adjusting members 420 are adjusted to the desired positions respectively, and finally the two adjusting members The first positioning holes 422 of 420 cooperate with the corresponding first positioning posts 411 of another position on the support 410, respectively, so that the connection positions of the two adjusting members 420 and the support 410 can be achieved along the axial direction of the push rod 200 It is adjusted and fixed relative to the installation of the support 410, so that the connection positions of the first travel switch 500 and the second travel switch 600 and the support 410 can be adjusted along the axial direction of the push rod 200 and fixed relative to the installation of the support 410.
