[0028] The embodiments of the present utility model will be further described below with reference to the accompanying drawings:

[0029] As shown in the figure, a pressing mechanism of a wire clamp includes a pressing block 1 and a screw 2. A passing groove 3 is provided on the lower surface of the pressing block 1. A convex platform 4 that is slidably matched with the passing groove 3 is provided at the upper end of the screw 2. A positioning structure that confines the screw 2 to only rotate and not move horizontally is provided between the upper surface of the convex platform 4 and the pressing block 1 at the middle position of the passing groove 3. In this technical solution, the screw is slidably installed along the passing groove at the middle position of the pressing block, and then the accurate positioning of the screw and the pressing block is ensured by setting the positioning structure and the through hole. After installation, the screw and the pressing block can complete relative rotation but will not move laterally, which has the advantages of simple structure and good practicability.

[0030] There are multiple embodiments of the positioning structure and the through hole in this technical solution, which are specifically as follows;

[0031] Embodiment 1, as Figure 2 shown, the passing groove 3 is adapted to the convex platform 4 and the cross-sections of both are T-shaped; the passing groove 3 is arranged along the length direction of the pressing block 1; the positioning structure adopts a rivet 6 and a first positioning hole 7. The pressing block 1 is provided with a mounting hole 5 for the rivet 6 to penetrate and be tightly fitted at the middle position. The first positioning hole 7 is located at the center of the upper surface of the convex platform 4 and is rotatably matched with the bottom end of the rivet 6. Move the screw to the middle position of the passing groove. The T-shaped passing groove can limit the convex platform up and down to prevent the screw from separating from the pressing block. Then align the rivet with the mounting hole 5 and the first positioning hole 7, and use a punching machine to drive the rivet in. The rivet is fixed in the mounting hole 5, and the bottom end of the rivet is rotatably matched with the first positioning hole; there is also a structure that the rivet is riveted to the first positioning hole and the rivet is rotatably matched with the mounting hole. The structural principle of this structure is the same as that of Embodiment 1.

[0032] Embodiment 2, as Figure 3 shown, the passing groove 3 is adapted to the convex platform 4 and the cross-sections of both are T-shaped; the passing groove 3 is arranged along the width direction of the pressing block 1; the positioning structure adopts a rivet 6 and a first positioning hole 7. The pressing block 1 is provided with a mounting hole 5 for the rivet 6 to penetrate and be tightly fitted at the middle position. The first positioning hole 7 is located at the center of the upper surface of the convex platform 4 and is rotatably matched with the bottom end of the rivet 6. This embodiment is the same as Embodiment 1, and the difference lies in that the setting direction of the passing groove is different from that of Embodiment 1.

When the boss slides in the passing groove, due to the existence of the bump, the boss and the passing groove are tightly fitted. The operator needs to push the screw rod forcefully until it moves to the second positioning hole at the middle position of the passing groove, and the bump is adapted to the second positioning hole and plays a positioning role.

[0034] Embodiment 4, as Figure 5 As shown, the passing groove 3 is adapted to the boss 4 and the cross-sections of both are T-shaped; the passing groove 3 is arranged along the width direction of the pressing block 1; the positioning structure adopts the bump 8 and the second positioning hole 11, the bump 8 is arranged at the center of the upper surface of the boss 4, and the second positioning hole 11 is arranged at the middle position of the pressing block 1 and corresponds to the bump 8; this embodiment is the same as Embodiment 3, and the difference lies in that the arrangement direction of the passing groove is different from that of Embodiment 3.

When the screw rod is moved to the middle position of the passing groove 3, the first bolt is inserted into the counterbore 12 and is in threaded cooperation with the boss. The first bolt can rotate freely in the counterbore. The contact and cooperation between the first bolt and the counterbore can limit the downward movement of the screw rod, and the contact and cooperation between the upper surface of the boss and the upper bottom surface of the passing groove can limit the upward movement of the screw rod.

[0036] Embodiment 6, as Figure 7 As shown, the passing groove 3 is arranged along the width direction of the pressing block 1; the positioning structure adopts the first bolt 9 that is in threaded cooperation with the boss 4, and the pressing block 1 is provided with a counterbore 12 that is rotatably fitted with the first bolt 9 at the middle position of the passing groove 3. This embodiment is the same as Embodiment 5, and the difference lies in that the arrangement direction of the passing groove is different from that of Embodiment 5.

[0037] Embodiment 7, as Figure 8As shown, the passing groove 3 is adapted to the convex platform 4 and the cross-sections of both are T-shaped; the passing groove 3 is arranged along the length direction of the pressing block 1; the positioning structure adopts a second bolt 10 that is in threaded cooperation with the convex platform 4, and the pressing block 1 is provided with a through hole 13 that is rotationally matched with the second bolt 10 at the middle position of the passing groove 3; when the screw rod is moved to the middle position of the passing groove, the T-shaped passing groove can limit the convex platform up and down to prevent the screw rod from separating from the pressing block, and the second bolt passes through the through hole and is connected to the convex platform as a whole, and the through hole plays a lateral limiting role for the second bolt but does not prevent the free rotation of the second bolt.
