[0044] Embodiment 2

[0045] The working method of the nail feeding and riveting device in the upper mold for small spaces is as follows:

[0046] The vibrating tray 1 first transports the screws along the nail outlet channel 1.1 to the first nail outlet hole (not shown in the figure) of the nail receiving plate 2.1 of the nail misalignment unit 2. Then, under the drive of the lateral movement mechanism 2.2, the nail receiving plate 2.1 switches from the nail receiving position to the nail pushing position. Then, the pushing cylinder 3.3 of the nail pushing unit 3 drives the push rod 3.2 to push the screw in the first nail outlet hole (not shown in the figure) out of the first nail outlet hole (not shown in the figure). The screw passes through the second nail outlet hole 14.1 of the baffle 14 until it falls into the positioning stepped hole 6.2 of the screw positioning side block 6. The upper mold part moves downward, and the pressing plate 12 presses the floating plate 5 downward. At the same time, under the action of the inclined wedge 10, the screw positioning side block 6 expands outward, so that the positioning stepped hole 6.2 expands, and the bottom end of the screw enters the riveting hole of the strip 13. The upper mold part continues to move downward. Under the action of the inclined wedge 10, the screw positioning side block 6 continues to expand outward until the screw completely enters the riveting hole of the strip 13. Then, the upper mold part continues to move downward until the punch 11 touches the top end of the screw and rivets the screw into the strip 13. Then, the upper mold part moves upward, the floating plate 5 resets upward to the initial state, and the screw positioning side block 6 resets to the initial state. Then, the riveting operation of the next screw is carried out.

[0047] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both the upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0048] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0049] The above is an exemplary description of the present utility model. It should be noted that without departing from the core of the present utility model, any simple deformation, modification, or equivalent replacement that can be made by those skilled in the art without creative labor falls within the protection scope of the present utility model.
