The two supporting blocks 46 are located at two sides below the mounting seat 43, the two supporting blocks 46 are arranged oppositely, the two supporting blocks 46 are trapezoidal, a linear guide rail 461 is fixed on the inclined plane 462 at the outer side of the supporting block 46, the extending direction of the linear guide rail 461 is consistent with the extending direction of the inclined plane 462 at the outer side of the trapezoidal shape of the supporting block 46, that is, the linear guide rail 461 gradually inclines towards the outer side from top to bottom, a sliding block 451 is respectively fixed on the two movable seats 45, the two sliding blocks 451 are respectively and slidably mounted on the two linear guide rails 461, that is, the movable seats 45 have the freedom degree of movement relative to the supporting block 46 along the linear guide rail 461, and the two pressing blocks 47 are respectively mounted on the two movable seats 45; in addition, a fixed rod 44 is fixed on each of the two movable seats 45, the fixed rods on the two movable seats 45 extend upwards to the side of the mounting seat 43, two guide grooves 431 are arranged on the mounting seat 43, the two guide grooves 431 are symmetrically arranged, the guide grooves 431 incline towards the middle of the mounting seat 43 from top to bottom, the top ends of the two fixed rods 44 are respectively penetrated in the two guide grooves 431, and the top ends of the fixed rods 44 have the freedom degree of moving along the extending direction of the guide grooves 431; a gap is formed between the two supporting blocks 46, an adjusting mechanism is arranged between the two supporting blocks 46 for adjusting the width of the gap to change the distance between the two supporting blocks 46, specifically, the adjusting mechanism comprises a fixing block 49, the fixing block 49 is positioned at one side of the two supporting blocks 46, a long groove 463 extending transversely is arranged on the supporting block 46, a fastening bolt (not shown) is connected in the long groove 463 in a penetrating manner, the fastening bolt penetrates through the long groove and then penetrates the fixing block 49 to lock the supporting block 46 on the fixing block 49, when the distance between the two supporting blocks 46 needs to be adjusted, the fastening bolt is loosened, the position of the fastening bolt in the long groove 463 is adjusted, and the distance between the two supporting blocks 46 can be changed.

Referring to fig. 3, during pressing, the mobile phone housing 90 is placed in the positioning slot of the positioning fixture 30, the two pressing blocks 47 located below the two sides of the pressing component 40 are pressed down simultaneously, and simultaneously the antennas at the two ends of the mobile phone housing 90 are pressed, so that the two antennas are respectively attached and fixed at the two ends of the mobile phone housing 90, because the top end of the fixing rod 44 is pressed by the upper side wall of the guiding slot 431, the fixing rod 44 does not generate relative displacement with the mounting seat 43 during pressing, so as to ensure that the pressing operation can be performed normally, meanwhile, when the mobile phone housings 90 with different sizes are pressed, the distance between the two pressing blocks 47 is changed by adjusting the distance between the two supporting blocks 46, so as to adapt to the size of the housing 90, specifically, when the housing 90 with smaller size is pressed, the supporting blocks 46 are moved toward the middle portion, and the movable seat 45 and the pressing blocks 47 are, meanwhile, the top end of the fixed rod 44 is pressed by the guide groove 431, so that the top end of the fixed rod 44 moves downwards along the guide groove 431, and the movable seat 45 drives the press block 47 to move along with the fixed rod 44 while the fixed rod 44 moves downwards along the linear guide rail 461, so that the displacement of the support block 46 moving towards the middle horizontally can be converted into the displacement of the press block 47 moving downwards and towards the middle simultaneously, namely the press block moves downwards for a certain distance while moving towards the middle; similarly, when the housing having a relatively large size is pressed, the supporting block 46 is moved outward, and the pressing block 47 is moved outward and upward at the same time by a predetermined distance. Therefore, the pressing block can adapt to the arc-shaped chamfer shapes of the edges of the shells with different sizes, so that the antenna pressing device not only can simultaneously press the antennas at two ends of the shell to improve the pressing efficiency, but also can better adapt to the shapes of the edges of the shells to improve the pressing quality of the antennas.

In order to facilitate the smooth sliding of the top end of the fixing rod 44 in the guide groove 431, the present invention has a roller 441 pivotally connected to the top end of the fixing rod 44, the roller 441 is embedded in the guide groove 431, and the edge of the roller 441 contacts and rolls with the side wall of the guide groove 431.

In the present invention, the linear guide 461 is used as a guiding component for guiding the movement of the pressing block 47 when adjusting the position of the pressing block 47, and other configurations are also possible, for example, a guiding hole extending from the top end surface to the bottom end surface of the supporting block 46 is provided, a guiding column slidably penetrating the guiding hole is fixed on the movable seat 45, or the fixing rod 44 slidably penetrates the guiding hole. Of course, the guide groove 431 may be a guide portion for guiding the sliding of the distal end portion of the fixed lever 44, and may have another configuration, for example, a guide rail provided to be inclined on the mounting base 43, and the distal end portion of the fixed lever 44 may be attached to the guide rail via a slider.

In a preferred embodiment, the connecting rod 471 is movably inserted into the movable seat 45, the bottom of the connecting rod 471 penetrates through the bottom of the movable seat 45, the top end portion of the pressing block 47 is fixedly connected to the bottom of the connecting rod 471, that is, the pressing block 47 and the movable seat 45 have a relative movement freedom, in addition, a spring 48 is further disposed between the pressing block 47 and the movable seat 45, the spring 48 is sleeved outside the connecting rod 471, two ends of the spring 48 respectively abut against the movable seat 45 and the pressing block 47, therefore, the elastic stress provided by the spring 48 always pushes the pressing block 47 downwards, so that the pressing block 47 always tends to move away from the movable seat 45, and thus, in the pressing process, after the pressing block 47 contacts the housing 90, the spring 48 is compressed, and the spring 48 plays a role of buffering, so as to prevent the pressing block 47 from rigidly impacting the housing 90. The spring 48 may be replaced by another elastic member, such as a rubber block having elasticity.
