[0034] This embodiment provides a snap-fit ​​assembly pen, including a pen barrel 1, a pen holder 2, a pen tip 3, a pressure rod 4, and a driving component, used to assemble the internal structure of a small product, that is, to install the component to be assembled inside the small product. The following will describe this in conjunction with... Figures 1 to 3 Describe in detail the specific structure, connection relationships, and working principles of these mechanisms.

[0035] In this embodiment, the pen holder 2 includes a cavity 22 extending through it along its axial direction. A pen barrel 1 and a pen tip 3 are respectively connected to one end of the pen holder 2. The pen barrel 1 extends the overall length of the snap-fit ​​assembly pen for easier gripping. A pressure rod 4 is located within the cavity 22 of the pen holder 2 and extends beyond one end of the pen holder 2. The pressure rod 4 can move along the extension direction of the cavity 22. The end extending from the pen holder 2 cooperates with the pen tip 3 to clamp and fix the part to be assembled. A driving component is located on the pen holder 2, and its driving end is connected to the pressure rod 4. The driving component can drive the pressure rod 4 to move along the extension direction of the cavity. In this embodiment, the part to be processed can be an antenna snap-fit. Small products have a circuit board structure. The purpose of the snap-fit ​​assembly pen is to clamp the antenna snap-fit ​​and assemble it to the connection end of the circuit board structure.

[0036] See Figure 2 As shown, in this embodiment, the pen tip 3 may include a body part 31, a portion of which extends into the cavity 22 of the pen holder 2 and is fixed together by bolts. The body part 31 has a groove extending through it along its axial direction, which makes the body part 31 present a U-shaped structure. The pen tip 3 also includes an extension part 32, which has two sets, respectively located at one end of the body part 31, specifically at the ends of two opposite side walls of the groove. The extension part 32 is an L-shaped plate. For ease of description, the section connected to the body part 31 is called the vertical section, and the part connected to the vertical section is called the horizontal section. The horizontal section extends toward the opening of the groove.

[0037] Preferably, each horizontal segment is provided with a slot, which is set along the opening direction of the groove. The lower sidewall of the slot forms a horizontal support part. The two support parts together can support the cover plate of the buckle. The opening directions of the two slots are set opposite to each other. The slot makes one end of the pen tip 3 form a holding space, and the cover plate of the buckle can be located in the holding space.

[0038] Furthermore, a notch is provided on the side of the support part away from the vertical section, and the corners of the notch on the support part are rounded. The notch makes the opposite sides of the support part have funnel-shaped guide openings, which facilitates the buckle to be inserted into the holding space.

[0039] In the embodiments, see Figure 2-3 As shown, the pressure rod 4 may include a rod body 41 and a pressure head 42. The pressure head 42 is an L-shaped plate with an anti-slip layer at its pressing end. The outer wall of the pressure head 42 protrudes relative to the rod body 41. A portion of the rod body 4 can extend into the groove of the main body 31 and move within the groove. Two limiting pins 33 are provided in the groove, and the rod body 41 is provided with a limiting elongated hole 43. All the limiting pins 33 pass through the limiting elongated hole 43. The distance between the upper and lower side walls of the elongated hole 43 and the nearest limiting pin 33 is the maximum stroke of the pressure rod 4 along the two extending counterclockwise movements of the cavity 22.

[0040] When the cover plate of the buckle has been inserted into the holding space, the driving component can drive the pressure rod 4 to move in the direction of the horizontal section, until the pressure head 42 of the pressure rod 4 abuts against the cover plate, and cooperates with the support end to clamp and fix the buckle, and then assemble the connection end of the buckle relative to the circuit board structure.

[0041] Preferably, the driving component includes a pressure plate 51, a holding member, and a connecting pin 53. The pressure plate 51 is used to assist in the installation of the holding member. The pen holder 2 is provided with an installation groove 21. The pressure plate 51 is installed in the installation groove 21 and the two are fixed together by bolts. The pressure plate 51 is provided with a strip groove through which the pressure plate 51 passes. The side of the pressure plate 51 near the pen holder 2 is provided with a limiting groove, which is larger than the strip groove. When the pressure plate 51 is installed in the installation groove 21, an installation cavity is formed between the limiting groove and the side wall of the pen holder 2. The base plate 522 of the holding member is located in the installation cavity.

[0042] Specifically, the holding component includes a handle 521, a base plate 522, and a connecting end 523. The handle 521, base plate 522, and connecting end 523 are connected sequentially. The mounting groove is provided with a movable elongated hole that penetrates one side wall of the pen holder 2. The length of the movable elongated hole along the extension direction of the cavity 22 is less than the length of the base plate 522 along the extension direction of the cavity 22 to ensure that the base plate 522 will not extend into the cavity 22, and is greater than the length of the connecting end 523 along the extension direction of the cavity 22 to ensure that the connecting end 523 can extend into the cavity 22 and move freely. The base plate 522 is locked in the mounting cavity. The connecting pin 53 connects the connecting end 523 and the rod 41 of the pressure rod 4. Pressing down the handle 521 can drive the pressure rod 4 to press down.

[0043] Preferably, the snap-fit ​​pen assembly further includes a reset component, which is disposed inside the cavity 22 of the pen holder 2. After the pressure rod 4 is pressed down, it is used to reset the pressure rod 4. The reset component includes a reset spring 6. The diameters of the cavities 22 are not uniform. Due to the non-uniformity of the diameters of the cavities 22, the diameter difference can form a blocking part on the inner wall of the cavity 22. The reset spring 6 is sleeved on the pressure rod 4, with one end abutting against the blocking part and the other end blocked by the connecting pin 53. The reset spring 6 is always in a compressed state.

[0044] Preferably, the snap-fit ​​assembly pen further includes an adjustment mechanism. The adjustment mechanism is used to adjust the extension and retraction of the pressure rod 4. The adjustment mechanism includes a set screw 71 and a fastening bolt 72. The set screw 71 is located inside the cavity 22. The fastening bolt 72 is used to fix the set screw 71 to a position in the cavity 22. The pressure rod 4 can abut against the set screw 71 under the elastic force of the return spring 6. The position of the set screw 71 in the cavity 22 is adjustable. When the snap-fit ​​assembly pen is placed vertically, the fastening bolt 72 is loosened, and the set screw 71 can fall down and abut against the pressure rod 4. The position of the set screw 71 can be positioned by adjusting the position of the pressure rod 4. After the position is determined, the fastening bolt 72 is tightened. During the process, the cavity 22 can guide and limit the set screw 71 to prevent it from tipping over.

[0045] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
