[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0014] Specific implementation method: Combination Figure 1-2As shown, a parallel groove wire clamp comprises a lower clamp seat 1 and an upper clamp seat 2, both of which are provided with at least one through hole, preferably three through holes, and a fastening bolt 3 passes through the through holes on the lower clamp seat 1 and the upper clamp seat 2 in sequence and is connected with a nut, and the two sides of the top surface of the lower clamp seat 1 are respectively provided with a first lower clamp groove 11 and a second lower clamp groove 12, and the two sides of the bottom surface of the upper clamp seat 2 are respectively provided with a first upper clamp groove 21 and a slide groove 22, and the bottom surface of the slide groove 22 is parallel to the bottom surface and the top surface of the upper clamp seat 2, and the inner surface of the slide groove 22 is parallel to the bottom surface and the top surface of the upper clamp seat 2. The sliding connection is provided with a slider 23, the length of which is less than the length of the slide slot 22, a baffle 221 is provided at one end of the slide slot 22, a threaded hole is provided on the baffle 221, a pushing bolt 222 that can push the slider 23 is connected to the threaded hole, and a second upper clamping groove 231 that runs through both ends of the slider 23 is provided on the bottom surface, the depth of the second lower clamping groove 12 decreases as the distance from the baffle 221 increases, and the depth of the second upper clamping groove 231 increases as the distance from the baffle 221 increases. Figure 2 As shown, moving the slider 23 to the left can increase the distance between the bottoms of the second upper clamping groove 231 and the second lower clamping groove 12, and moving the slider 23 to the right can reduce the distance between the bottoms of the second upper clamping groove 231 and the second lower clamping groove 12.
