DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
In a preferred embodiment of the present invention, fastened clamping box 1, removable box cover 2, fixed clamp plate 3 and floating clamp plate 4 are all made of metallic materials.
Fastened clamping box 1 is shaped to be concave, and on both edges of fastened clamping box 1, ledges 9 are made to hold removable box cover 2 in fastened clamping box 1. Securing bolt 5 is used to further secure the connection between fastened clamping box 1 and removable box cover 2.
Fixed clamp plate 3 and floating clamp plate 4, each with peg teeth 8 on a portion of the clamping surface, are positioned in fastened clamping box I where fixed clamp plate 3 is fastened by coupling bolt 6. Locking bolt 7 is mounted on removable box cover 2 to fix and lock floating clamp plate 4. The presence of ledges 9 and securing bolt 5 ensure that removable box cover 2, upon which locking bolt 7 is mounted, is securely in place to fix and lock floating clamp plate 4.
When the preferred embodiment of the present invention is being operated, locking bolt 7 is loosened and connected belt 10 is placed into the space between fixed clamp plate 3 and floating clamp plate 4. Locking bolt 7 is then tightened, thereby fixing and locking floating clamp plate 4.
By adopting the above preferred embodiment, there is no need to pierce the belt in clamping the connected belt to create a connection with the present invention, and the strength of the belt will not be affected thereby. Moreover, compared with the prior art, the preferred embodiment has the advantages of a reliable, working connection, convenient operation. The preferred embodiment will save time and labor, and can be used repeatedly.
From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the various embodiments of the invention. Further, while various advantages associated with certain embodiments of the invention have been described above in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the invention.
Accordingly, the invention is not limited, except as by the appended claims.
