In some embodiments, as shown in fig. 2, the first end of the first housing 12 is provided with a first blind hole 122, the first socket 121 is disposed at a bottom surface of the first blind hole 122, the third housing 21 includes a first bushing 212, the first plug 211 is disposed in the first bushing 212, and the first bushing 212 is fitted in the first blind hole 122 so that the first plug 211 is fitted with the first socket 121.
The arrangement of the first shaft sleeve 212 and the first blind hole 122 facilitates the alignment of the first plug 211 and the first socket 121, so that the plugging speed of the first plug 211 and the first socket 121 is increased, and convenience and rapidness are achieved.
In addition, the cooperation of the first boss 212 and the first blind hole 122 functions to restrict the radial movement of the first housing 12 and the third housing 21 in the first boss 212/the first blind hole 122, thereby improving the reliability of the connection of the first plug 211 and the first receptacle 121.
Specifically, the first housing 12 has a cylindrical shape, and the first blind hole 122 is coaxial with the first housing 12.
In some embodiments, as shown in fig. 1 and 3, a first annular groove 213 is formed on the peripheral wall of the first sleeve 212, a first through hole 123 communicating the first blind hole 122 with the outside is formed on the peripheral wall of the first housing 12, and the height measuring sensor further includes a first plug pin 4, and the first plug pin 4 is fitted in the first through hole 123 and the first annular groove 213.

Therefore, the first pin 4 has better axial limiting effect on the first shaft sleeve 212.
Specifically, the diameter of the formed annular circumferential surface of the first ring groove 213 is slightly larger than the distance between the two parallel portions of the first pin 4, and thus, when the first pin 4 is fitted in the first ring groove 213, the first pin 4 is elastically deformed outward, and then, an inward elastic force is generated, and thereby, the contact pressure with the annular circumferential surface of the first ring groove 213 is increased, so that the frictional force therebetween is increased, and the fixation of the first pin 4 is achieved.

The second shaft sleeve 132 and the second blind hole are arranged, so that the second plug 131 and the second socket can be aligned conveniently, the plugging speed of the second plug 131 and the second socket is increased, and convenience and rapidness are achieved.
In addition, the cooperation of the second bushing 132 and the second blind hole functions to restrict the radial movement of the second housing 13 and the fourth housing 31 in the second bushing 132/the second blind hole, thereby improving the reliability of the connection of the second plug 131 and the second receptacle.
Specifically, the fourth housing 31 has a cylindrical shape, and the second blind hole is coaxial with the fourth housing 31.
In some embodiments, as shown in fig. 1, the second annular groove 133 is disposed on the peripheral wall of the second shaft sleeve 132, the second through hole 311 is disposed on the peripheral wall of the fourth casing 31 for communicating the second blind hole with the outside, and the height measuring sensor further includes a second plug pin, and the second plug pin is fitted in the second through hole 311 and the second annular groove 133.
Thus, when the second plug 131 and the second socket are mated, the second bushing 132 is fitted in the second blind hole, and at this time, the second plug is fitted in the second annular groove 133 and restricts the second bushing 132 from sliding relative to the second blind hole in the axial direction thereof, thereby further improving the reliability and stability of the connection of the second plug 131 and the second socket.
In some embodiments, as shown in fig. 1, the number of the second through holes 311 is two, two sets of the second through holes 311 are symmetrical about an axis of the second blind hole, each set of the second through holes 311 includes two second through holes 311 symmetrical about a longitudinal section of the second blind hole, and the second latch is a U-shaped pin.
