1 is a perspective view of a fastening device for a carrier press fastener according to an embodiment of the present invention.

Fig. 2 is a perspective view of the fastening device shown in Fig. 1.

3 is a perspective view of the internal structure of the fastening device shown in FIG. 2, wherein the fastening device is in a first use state.

4 is a perspective view of the internal structure of the fastening device shown in FIG. 2, wherein the fastening device is in a second use state.

Referring to FIG. 1 , a fastening device 100 is provided for automatically fastening a plurality of crimping pins 12 on a carrier 200 .

Referring to FIG. 2 , the fastening device 100 includes a base 20 , a cylinder 30 fixed to the base 20 , a push block 40 fixed to the cylinder 30 , and a relative fixed to the base 20 and disposed on the cylinder 30 . A pair of support blocks 50 on both sides. The push block 40 includes a pair of figure-shaped wedge faces 401 formed on opposite sides of the push block, and each support block has a pair of inverted figure-shaped guide grooves 501 at an upper end thereof.

The fastening device 100 further includes a pair of sliders 60 respectively disposed on opposite sides of the push block 40 and abutting against the wedge surface 401 of the push block 40. The opposite ends of each of the sliders 60 are respectively engaged in the guiding chutes 501 of the pair of supporting blocks 50, and each of the sliders 60 can slide in the corresponding guiding chutes 501.

Referring to FIG. 3 , each press button 12 includes a fixing portion 121 fixed to a surface of the carrier 200 and a rotating portion 122 rotatably coupled to the fixing portion 121 . The rotating portion 122 and the fixing portion 121 are located on the same surface of the carrier 200 without external force.

In the present embodiment, each of the sliders 60 is away from a rotating end 122 of the press button 12 away from a free end of the push block 40. Referring to FIG. 4, when the cylinder 30 is lifted up to the push block 40, the wedge surface 401 is pressed outwardly to press the slider 60, so that the slider 60 approaches the corresponding guide slot 501. The buckle 12 slides in the direction of the buckle 12, and the free end of the slider 60 abuts against the rotating portion 122 of the buckle 12, so that the rotating portion 122 of the buckle 12 rotates and passes through the carrier 200 corresponding to the buckle 12 holes 201 (shown in FIG. 1) is fastened to the other surface of the carrier 200 so that the article (not shown) placed on the other surface of the carrier 200 can be buckled.
