Detailed Description

As shown in fig. 1 to 7, the staple storage and release assembly provided in this embodiment includes a staple storage sleeve 1, a plurality of position limiting and release members 2, and a sleeve 3. The nail storage sleeve 1 is provided with a nail storage channel 11 which axially penetrates through the nail storage sleeve and a plurality of release mounting holes 12 which are uniformly distributed on the same cross section position of the peripheral wall of the nail storage sleeve, and each release mounting hole 12 is communicated with the nail storage channel 11 along the radial direction. A plurality of spacing clearance parts 2 correspond respectively and set up in a plurality of clearance mounting holes 12, and each spacing clearance part 2 all includes rivet locating part 21 and pressure spring 22, and pressure spring 22 sets up in clearance mounting hole 12, and rivet locating part 21 is connected in the inner of pressure spring 22 and is stretched into and store up in the nail passageway 11, and when the pressure spring extended naturally, the inner of a plurality of rivet locating parts 2 was spacing rivet 10 in storing up nail passageway 11. The sleeve 2 is sleeved outside the nail storage sleeve 1 and covers the plurality of release member mounting holes 11, and the outer end of each pressure spring 22 abuts against the inner wall of the sleeve 2.

In this embodiment, as shown in fig. 3 to 5, three release member mounting holes are uniformly distributed on the circumferential wall of the nail storage sleeve 1, and the three limiting release members 2 are respectively and correspondingly disposed in the three release member mounting holes 12. However, the present invention is not limited thereto. In other embodiments, two or more release member mounting holes can be uniformly distributed on the peripheral wall of the nail storage sleeve; correspondingly, the nail storage release assembly can also comprise two or more than four limiting release pieces.

In the embodiment, the rivet retaining member 21 is a spherical ball, and the spherical surface is more favorable for the rivet 10 to pass through. However, the present invention is not limited thereto. In other embodiments, only the inner end surface of the rivet retaining member may be a circular arc surface or an inclined guide surface.

In the storage nail clearance subassembly that this embodiment provided, the rivet of rivet pay-off output gets into and stores up nail passageway 11, and three storage nail clearance 2 carries on spacingly to rivet 10 to save the rivet in rivet passageway 11, realize storing up the nail. Preferably, the three nail storage release parts 2 are arranged on the lower side wall of the nail storage sleeve 1 and close to the bottom of the nail storage sleeve 1; this arrangement maximizes the length of the rivet channel 11 so that a variety of different length rivets can be accommodated within the rivet storage channel 11. However, the present invention is not limited thereto.

When rivets are needed, an external thimble extends into the rivet storage channel 11 and pushes the rivets 10, and the front ends of the rivets 10 extend into gaps formed by the inner ends of the three rivet limiting pieces 21 and extrude the rivet limiting pieces 21 along the radial direction. Because the rivet limiting piece 21 is connected to the pressure spring 22 and the outer end of the pressure spring 22 abuts against the inner wall of the sleeve 3, the pressure spring 22 is compressed due to the extrusion of the rivet 10, the rivet limiting piece 21 moves backwards along the radial direction along with the pressure spring 22, and the rivet 10 penetrates through the gap formed by the inner ends of the three rivet limiting pieces 21 and is gradually discharged from the rivet channel 11, so that the release of the rivet is realized.

In the present embodiment, when the rivet 10 is discharged, the diameter of the inscribed circle formed by the inner ends of the three rivet stoppers 21 is equal to the diameter of the rivet 10. Therefore, the rivet can be released in a plurality of different lengths and different diameters in the compression range of the pressure spring 22, and the universality is very good. Furthermore, three spacing clearance pieces 2 that evenly distribute along the circumference of storing up nail cover 1 then can adjust rivet 10 exhaust direction, avoid the rivet slope to discharge or the slope card dies in storing up nail passageway 11, have reduced the fault rate when improving riveting quality.

In order to further realize the adjustment of the direction of the rivet 10 in the rivet channel 11 to avoid the rivet from inclining at a large angle, in this embodiment, the rivet releasing assembly further includes two layers of adjusting assemblies disposed above the three releasing position-limiting members 2. Each layer of adjusting component comprises three adjusting pieces 4 which are uniformly distributed along the peripheral wall of the nail storage sleeve 1.

The diameter of an inscribed circle defined by the inner ends of the three adjusting pieces 4 on the same layer is larger than that of the rivet, and the diameter of the inscribed circle of the upper adjusting layer assembly 100 is larger than that of the lower adjusting layer assembly 200. This arrangement allows the upper and lower adjustment layer assemblies 100 and 200 to sequentially adjust the angle of inclination of the rivets after the rivets 10 enter the rivet passages 11, but without obstructing the passage of the rivets 10, so that the rivets 10 can be discharged as far as possible along the center of the rivet passages 11 during discharge. However, the number of layers of the adjusting assembly and the number of adjusting members in each layer of the adjusting assembly are not limited in the present invention. In other embodiments, one or more than three layers of adjusting components can be provided. When the multi-layer adjusting assembly is provided, the diameter of an inscribed circle defined by the inner ends of the adjusting pieces 4 in the upper layer of adjusting assembly is larger than that of an inscribed circle defined by the inner ends of the adjusting pieces 4 in the lower layer of adjusting assembly.

In the present embodiment, as shown in fig. 5 to 7, three releasing stoppers 2, three adjusting members 4 on the lower adjusting layer assembly 200, and three adjusting members 4 on the upper adjusting layer assembly 100 are uniformly and correspondingly disposed. However, the present invention is not limited thereto.

Similar to the structure of the position-limiting releasing element 2, in the present embodiment, each adjusting element 4 includes an adjusting steel ball 41 and an adjusting pressure spring 42, and the sleeve 3 is covered with two layers of adjusting components. The outer end of the adjusting pressure spring 42 abuts against the inner wall of the sleeve 3. The adjustment compression spring 42 provides adjustment space and radial adjustment force for the inclined rivet. However, the present invention is not limited thereto. In other embodiments, other elastic members may be used as the adjusting member, such as elastic silica gel column with good restoring force.

Since the rivet limiting member 21 is a spherical steel ball, in order to prevent the rivet limiting member from shaking during radial movement, in this embodiment, a limiting portion 121 protruding into the release member mounting hole is provided at a position corresponding to the spherical steel ball at the inner end of the release member mounting hole 12, and the spherical steel ball is limited by the limiting portion 121. However, the present invention is not limited thereto.

In this embodiment, the magazine 1 includes an upper housing 101 and a lower housing 102, the wall thickness of the lower housing 102 is larger than that of the upper housing 101, and three release member mounting holes 12 are formed in the lower housing 102. The lower sleeve body 102 with the thicker thickness provides a space for installing the pressure spring 22; the upper sheath body 101 with only the nail storage channel 11 can adopt a thinner wall thickness to reduce the cost and weight of the product. However, the present invention is not limited thereto. In other embodiments, the upper sleeve body and the lower sleeve body can have the same wall thickness.

In this embodiment, as shown in fig. 7, the inlet end of the magazine channel 11 is formed with an inclined flared shape to facilitate the entry of the rivets 10 into the magazine channel 11.
