Then manipulator drive centre gripping subassembly 92 moves forward gradually, send into the material loading hole of terminal machine 93 with the tip of wire 3, until line cardboard 921 is close to the material loading hole, wire 3 is difficult to continue to insert the material loading hole, and ninth driving piece 924 lifts up line cardboard 921 this moment, and tenth driving piece 925 retracts line cardboard 921 backward, only by clamping jaw 923 clip sleeve pipe 2 can. After the terminals are punched, the sensors are removed from the terminal block 93.

In order to prevent the sensor body 1 from dropping, a set of inclined clamping jaws may be installed behind the clamping jaws to clamp the sensor body.

The other structure of this embodiment is the same as embodiment 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
