The width of the escape space 200a in the front-rear direction matches the length of the bulk part 300 in the front-rear direction. Thus, when the second mounting fixture 50 gradually approaches the first mounting fixture 30, the positioning block will gradually approach the end face of the receiving end of the main body portion 200; then, when the second mounting fixture 50 is further close to the first mounting fixture 30, the end face of the receiving end of the main body portion 200 will abut against the positioning block and drive the positioning block to retract; at this time, the distance that the two positioning blocks yield is followed by the end face of the accommodating end, although the two positioning blocks gradually release the two ends of the spare part 300, the two ends of the spare part 300 simultaneously enter the avoidance space 200a (as shown in fig. 8), so that the stability of the spare part 300 in the alignment and assembly processes is ensured, the smooth proceeding of the penetrating process of the rotating shaft is facilitated, the assembly convenience and the assembly efficiency of the limiting mechanism inside the headphone are facilitated, and the quality of a finished product is improved.

It should be noted that, for the expansion and contraction of the positioning block, at least the following manner may be implemented: a positioning hole is formed in the positioning plate 51 at a position for mounting the positioning block (a positioning hole is formed in each of two ends of the surface of the substrate 71 facing the first mounting fixture 30 at the positioning groove 50 a), a spring is inserted into the positioning hole, and one end of the spring is fixedly connected to the bottom wall of the positioning hole, and the other end of the spring is fixedly connected to the surface of the positioning block facing away from the first mounting fixture 30. Of course, for the expansion and contraction of the positioning block, those skilled in the art may also adopt other effective and reasonable manners, which are not described in detail herein.

Further, in order to improve the stability of the installation of the spare part 300 in the positioning groove 50a, the following configuration may be further performed for the second installation jig: the alignment plate 51 is further provided therein with a magnetic member, which is located at the rear of the positioning slot 50a and is used for magnetically attracting the component part 300. Thus, when the material capable of generating magnetic attraction with the magnetic member exists in the part 300, the part 300 can be further enhanced in magnetic attraction, so that the stability of the part 300 mounted in the positioning groove 50a is further improved.

As shown in fig. 1 and 2, in an embodiment of the tooling fixture 100 of the present invention, the tooling fixture 100 further includes a translation mechanism 90, and the second mounting fixture 50 is disposed on the translation mechanism 90 so as to be close to or far from the first mounting fixture 30 under the driving of the translation mechanism 90.

Specifically, a support is arranged on the sliding table 91, the support is provided with a bearing surface facing the first installation jig 30, two positioning columns are arranged on the bearing surface along the horizontal direction at intervals and used for being in plug-in fit with the alignment plate 51, and the alignment plate 51 is fixed on the sliding table 91. A connecting block is also convexly arranged above the alignment plate 51 on the bearing surface, and a second precession structure is arranged on the surface of the connecting block, which is opposite to the alignment plate 51; when the second screw-in structure rotates relative to the connecting block, one end of the second screw-in structure facing the alignment plate 51 gradually protrudes out of the surface of the connecting block facing the alignment plate 51, and gradually approaches the alignment plate 51 until abutting against the alignment plate 51. Thus, the alignment plate 51 can be locked by the abutment action of the second screw-in structure. In the opposite process, release of the alignment plate 51 is achieved. Thus, the second mounting fixture 50 can be dismounted on the sliding table 91; thus, when the component part 300 of the headphone inner limit mechanism needs to be mounted to the second mounting position of the second mounting jig 50, the second mounting jig 50 can be detached from the slide table 91 in advance; then, the spare part 300 is mounted to a second mounting position for fixing; finally, the second mounting jig 50 with the component part 300 mounted thereon is then assembled back onto the slide table 91. It can be appreciated that in this process, the installation of the component part 300 is not affected by the position of the console 10, and an operator can select a suitable and convenient installation position and installation scheme according to actual requirements to perform installation work, so that the operation convenience of the tool fixture 100 is further improved. In addition, by utilizing the matching of the sliding table 91 and the track 92, the second installation jig 50 can slide relative to the operation table 10, so that the stability of the second installation jig 50 in the moving process can be improved, and the device is simple in structure, convenient to manufacture and rapid to assemble.
