Among them, the coupling forms a coupling receiving end 22, the output shaft forms an output shaft end 21, the coupling receiving end 22 is provided with a receiving hole, and the output shaft end 21 is provided with external threads. To realize the connection between the connector 2 and the connection housing 1, the connector 2 passes through the opening and is located in the receiving space 13, the output shaft end 21 extends into the receiving hole of the micrometer head receiving end 11, and the output shaft end 21 is rotationally connected with the receiving hole of the micrometer head receiving end 11 through threads, so as to make the central axis of the connector 2 coincide with the central axis of the connection housing 1. As Figure 4 shown, two symmetrically arranged radial grooves 222 are provided at the coupling end. The radial grooves 222 are provided through the side wall of the receiving hole, and corresponding fastening threaded holes 221 are opened on both sides of each radial groove 222. Fasteners 4 are adapted to penetrate into the fastening threaded holes 221, and the fasteners 4 are adapted to the fastening threaded holes 221. Specifically, the fasteners 4 are bolts.

[0052] As Figure 1 、 Figure 2As shown, the T-block 3 is provided with a connecting rod 32. To fix the connecting rod 32, as Figure 1 , Figure 2 shown, the fastener 4 passes through the fastening threaded hole 221, and the width of the radial groove 222 is adjusted by the fastener 4 to lock the T-block 3, locking the T-block 3 within the coupling receiving end 22, and the central axis of the connecting rod 32 of the T-block 3 coincides with the central axis of the connecting member 2.

[0053] A coater includes the above-mentioned integral differential head, and also includes a coating die head, and the coating die head is fixedly connected to the connecting housing 1.

[0054] The integral differential head provided by the present utility model has the following advantages: (1) The output shaft of the differential head and the coupling are integrally processed. Compared with the prior art, the coupling does not need to be installed and connected to the output shaft of the differential head, reducing the loosening probability of the coupling, and at the same time improving the installation coaxiality and assembly accuracy; (2) The T-block 3 is locked by the fastener 4, and the entire installation process is relatively convenient, reducing the installation process and improving the installation efficiency; (3) By integrally processing the output shaft of the differential head and the coupling, the present application only needs to adjust the coaxiality between the T-block 3 and the coupling receiving end 22, reducing the adjustment difficulty of the coaxiality and improving the overall coaxiality.

That is, by controlling the rotation of the fastener 4, the width of the radial groove 222 is changed to lock the connecting rod 32. Specifically, the fastener 4 is a nut. The other structures of this application are the same as those of Embodiment 1.

[0060] As Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the coupling receiving end 22 is provided with a circumferential groove 223 and a radial groove 222. The circumferential groove 223 and the radial groove 222 intersect, and a deformation part is formed between the circumferential groove 223 and the radial groove 222. Fastening threaded holes 221 are respectively opened on the side walls on both sides of the radial groove 222, and the fastening threaded holes 221 are adapted to pass through the fastener 4. Specifically, the fastener 4 is a bolt. Since the coupling receiving end 22 has a movable part that can move, by inserting the fastener 4 into the fastening threaded hole 221, the width of the radial groove 222 can be adjusted to lock and fix the connecting rod 32 of the T-block 3. The other structures of this application are the same as those of Embodiment 1.

[0061] As an alternative implementation, the number of the radial grooves 222 in Embodiment 3 can also be 4, 5 or even more.
