The second locking member 21 includes a support seat 22, and a socket 23 matching the plug 12 is arranged in the support seat 22. A clamping groove 24 matching the clamping protrusion 13 is arranged on one side of the support seat 22. The plug 12 is inserted into the socket 23, and the clamping protrusion 13 is clamped with the clamping groove 24, so that the push piece 10 and the slide lock 20 are connected.

[0029] Optionally, in this embodiment, the push piece 10 is made of engineering plastic, which will not be magnetized by the electromagnetic coil during the use of the electronic differential, eliminating the danger of residual magnetism, avoiding the adsorption of metal impurities that may cause wear on the surface of the mechanism and the consequences of movement jamming, and avoiding the generation of metal impurities due to friction; further, a plurality of first locking members 11 are evenly spaced on the side of the push piece 10 opposite to the slide lock 20, and a second locking member 21 is evenly spaced on the side of the slide lock 20 opposite to the push piece 10.

It can be understood that since the push piece 10 is made of engineering plastic as a whole and has a certain elasticity, the snap-fitting of the snap-fitting protrusion 13 and the snap-fitting groove 24 can be achieved after the plug 12 is inserted into the socket 23.

[0030] Optionally, in this embodiment, five first locking members 11 are provided at equal intervals on the push piece 10, and five second locking members 21 are provided at equal intervals on the slide lock 20.
