Preferably, the bolt passes two the bar hole, and install the nut, the one end of bolt keeps off with the port department in bar hole and connects, and the nut keeps off with the port department in another bar hole and connects.

Compared with the prior art, the invention has the following beneficial effects: install two in the inner wall of two semicircle boards, fixed shelves strip keeps off the side of pressing from both sides tight arc piece, avoids dropping, then breaks two semicircle boards off with the fingers and thumb, will twine the cable of preformed armor rod and arrange two tight arc pieces of clamp in between, then closes two semicircle boards, and the bolt passes the bar hole to install the nut on the bar hole, tighten the nut, make the inseparable centre gripping cable of tight arc piece of clamp, this preformed suspension clamp centre gripping is effectual.

Drawings

The invention is described in further detail below with reference to the following figures and detailed description:

FIG. 1 is a schematic overall structure of the present invention;

fig. 2 is a schematic structural view of part a of the present invention.

In the figure: the device comprises 1-H-shaped connecting blocks, 2-E-shaped connecting blocks, 3-semicircular plates, 4-fixed stop bars, 5-clamping arc-shaped blocks, 6-fixed blocks, 7-strip-shaped holes and 8-bolts.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1-2. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The invention provides a technical scheme that: the utility model provides a preformed helical suspension clamp, includes H type connecting block 1, H type connecting block 1 is close to the lateral wall of bottom and has two chevron type connecting blocks 2 that the symmetry set up, two through round pin axle swivelling joint two semicircle boards 3 of the bottom fixedly connected with of chevron type connecting block 2, two fixed shelves strips 4 of the inner wall fixedly connected with of semicircle board 3 to and the inner wall activity is provided with and presss from both sides tight arc piece 5, two fixed blocks 6 of the bottom fixedly connected with of semicircle board 3, two bar holes 7, two have been seted up to the lateral wall of fixed block 6 install bolt 8 in the bar hole 7.
