In another embodiment of the present application, one of the mounting seat 10 and the sliding block 41 is provided with a groove, and the other of the mounting seat 10 and the sliding block 41 is provided with a protrusion 17, and when the sliding block 41 slides to a preset position, the protrusion 17 abuts into the groove.

In the present embodiment, illustratively, as shown in fig. 3 and 4, the slider 41 is provided with a groove (not shown), and the mount 10 is provided with the projection 17, and when the slider 41 slides to the preset position, the projection 17 abuts into the groove. Specifically, the preset position may be a position of the slider 41 in the sliding groove 16 when the signal input end 42 on the slider 41 contacts with a signal transmission contact of the earphone to be tested of the profiling cavity 30, and when the slider 41 is at the preset position, the protrusion 17 abuts against the groove, and plays a certain limiting role for the slider 41, so that the slider 41 can be prevented from sliding freely in the sliding groove 16, thereby ensuring stable signal transmission between the signal input end 42 and the signal transmission contact of the earphone to be tested, and being beneficial to improving the accuracy of the pressure test result. In addition, the bulge 17 is abutted to the groove to play a role in reminding, so that a tester can be reminded that the sliding block 41 reaches a preset position, and the sliding block 41 is prevented from excessively sliding to damage the signal input end 42 and a signal transmission contact of the earphone to be tested.

When the slider 41 is separated from the slide groove 16, the spring 60 is in a non-compressed state, and the protrusion 17 protrudes from the surface of the slide groove 16. When the slider 41 is placed in the sliding groove 16 and the accommodating groove 18 and the recess are staggered in position, the spring 60 is compressed under the action of the gravity of the slider 41, and the protrusion 17 is accommodated in the accommodating groove 18 without being exposed. When the sliding block 41 slides to the preset position, the groove is just opposite to and communicated with the accommodating groove 18, at this time, the protrusion 17 automatically protrudes out of the surface of the sliding groove 16 under the elastic force of the spring 60 and is abutted into the groove, so that the protrusion 17 is automatically abutted into the groove through the matching between the sliding block 41 and the sliding groove 16.

Further, the protrusion 17 can be in a hemispherical shape, and the groove is in a hemispherical shape, so that the protrusion 17 can be abutted into the groove and separated from the groove more easily, and the normal sliding of the sliding block 41 in the sliding groove 16 is ensured.

Furthermore, a stop block 19 is arranged at the end part of the sliding groove 16 close to the connecting hole 15, and the stop block 19 has a limiting effect on the sliding block 41. When the sliding block 41 slides in the sliding groove 16 to the preset position, the sliding block 41 just abuts against the blocking block 19, so that the sliding block 41 can be prevented from excessively sliding to damage the signal input end 42 and a signal transmission contact of the earphone to be tested.

Further, the mounting seat 10 includes a bottom plate 101 and two side plates 102 connected to two opposite sides of the bottom plate 101, the bottom plate 101 and the two side plates 102 jointly enclose the sliding slot 16, and ends of the two side plates 102 away from the bottom plate 101 are bent toward each other to form a flange portion 1021. The slider 41 includes a connecting portion 411 and a sliding portion 412, the signal input end 42 and the signal output end 43 are both disposed on the connecting portion 411, one side of the sliding portion 412 is connected to the connecting portion 411, the other side of the sliding portion 412 is slidably connected to the sliding slot 16, a groove is disposed on a side portion of the sliding portion 412 slidably connected to the sliding slot 16, and opposite ends of the sliding portion 412 are respectively abutted to the lower portions of the two flange portions 1021. Thus, when the protrusion 17 abuts against the inside of the groove or is separated from the groove, the sliding part 412 does not bounce up and down under the blocking of the flange part 1021, i.e. the sliding block 41 can be ensured to slide smoothly along a straight line, thereby ensuring the accurate butt joint of the signal input end 42 and the signal transmission contact of the earphone to be tested.

As shown in fig. 5, when the rotating member 52 is rotated clockwise, the first hinge point moves backward and upward, and the pushing member 51 cannot move along the radial direction of the through hole 551 due to the limiting effect of the pushing member 51 on the through hole 551, so that the second hinge point can only move backward, and at this time, the linkage members 53 both rotate relative to the rotating member 52 and the pushing member 51, the rotating direction is counterclockwise, and the pushing member 51 is driven to move backward; when the rotating member 52 is rotated counterclockwise, the first hinge point moves forward and downward, the second hinge point moves forward, and at this time, the linkage members 53 rotate relative to the rotating member 52 and the pushing member 51, and the rotating direction is clockwise, and the pushing member 51 is driven to move forward.

In another embodiment of the present application, as shown in fig. 2, 5 and 6, the pushing member 51 includes a pushing rod 511, a first abutting block 512 and a second abutting block 513, the pushing rod 511 penetrates through the signal transmission assembly 40, and both the first abutting block 512 and the second abutting block 513 are fixedly sleeved on the pushing rod 511 and abut against two opposite side portions of the signal transmission assembly 40, respectively.

In the embodiment of the present application, the first abutting block 512 and the second abutting block 513 are both fixedly sleeved on the push rod 511, the first abutting block 512 abuts against the side of the signal transmission device 40 close to the contour groove, and the second abutting block 513 abuts against the side of the signal transmission device 40 far from the contour groove, so that the fixed connection between the push rod 511 and the signal transmission device 40 is realized. The first abutting block 512 is used for pulling the signal transmission assembly 40 to move in a direction away from the contour groove, and the second abutting block 513 is used for pushing the signal transmission assembly 40 to move in a direction away from the limiting groove.

Further, the push rod 511 includes a fixing bolt 5111 and a connecting shaft 5112, the fixing bolt 5111 is screwed into the connecting shaft 5112, the end portion of the connecting shaft 5112 far from the fixing bolt 5111 is connected with the linkage piece 53, the first abutting block 512 is a head portion of the fixing bolt 5111, the second abutting block 513 is a nut, and the second abutting block 513 is screwed onto the fixing bolt 5111 and is located between the first abutting block 512 and the connecting sleeve. During installation, the fixing bolt 5111 is inserted into the signal transmission assembly 40, the head of the fixing bolt 5111 abuts against the side portion of the signal transmission assembly 40 close to the contour groove, then the nut is screwed on the fixing bolt 5111 and abuts against the side portion of the signal transmission assembly 40 far away from the contour groove, and then the connecting shaft 5112 is screwed on the fixing bolt 5111, so that the assembly of the push rod 511 and the signal transmission assembly 40 is realized, and the operation is simple and quick.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
