After the press fitting is finished, a worker rotates the rotating block 46, so that the extending block 414 is shifted upwards, the spring pushing block 48 is lifted upwards under the influence of the extending block 414, the rotating block 46 is connected with the extending block 414, the rotating block 46 rotates upwards from bottom to top, and the sliding plate 454 is connected below the spring pushing block 48, so that the sliding plate 454 is driven to move upwards when the spring pushing block 48 is lifted upwards, the extending block 414 in the cushion block 41 shifts the elastic sheet 481, the elastic sheet 481 is connected with the pushing frame 45, when friction is generated between the elastic sheet 481 and the rotating block 413, the attaching position between the attaching groove 433 and the sliding shaft 67 is changed, the attaching groove 433 is far away from the surface of the sliding shaft 67, and the push rod 44 withdraws pushing the arc pressing plate 63, so that the arc pressing plate 63 is reset.
When the rotating block 46 rotates to drive the pushing frame 45 to slightly lift, the clamping plate 43 is connected to the surface of the pushing frame 45, and then the clamping plate 43 moves upwards, the attaching groove 433 slides on the surface of the sliding shaft 67, the sliding shaft 67 rotates between the connecting shafts 66, the attaching relation between the attaching groove 433 and the sliding shaft 67 is changed, and the pushing force of the ejector rod 44 on the arc pressing plate 63 is changed, so that the arc pressing plate 63 is reset in a rebound manner.
The cover piece 485 cover is established on bull stick 415 surface, when extension piece 414 stir bending piece 482, bending piece 482 receives the extrusion and produces deformation to drive shell fragment 481 upwards to lift, and drive arc piece 484 and joint board 483 upwards move, because arc piece 484 is the elastic material, push away extrusion frame 45 and drop down arc piece 484 when upwards moving, thereby make push extrusion frame 45 produce slightly to lift up, make laminating groove 433 and the laminating point change between the slide shaft 67, be convenient for stabilize subassembly 4 and reset, relax the centre gripping to the axis after the pressure equipment is accomplished, make things convenient for the axis to take out.
It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art and which are included in the embodiments of the present invention without the inventive step, are intended to be within the scope of the present invention. Structures, devices and methods of operation not specifically described and illustrated herein, unless otherwise indicated and limited, are implemented according to conventional means in the art.
