[0010] In some embodiments, the other end of the locking housing has two symmetrically distributed limiting portions, and the two limiting portions respectively abut against the ends of the first pressing block and the second pressing block far from the locking bolt.
[0011] In some embodiments, a receiving space is formed between the supporting portion and the two limiting portions, and the wire clamp body is placed in the receiving space.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0025] As Figure 1 、 2 shown, an adjustable C-type wire clamp includes a locking housing 1 and a wire clamp body 2 disposed in the locking housing 1. First pressing blocks 3 and second pressing blocks 4 are respectively disposed in the C-shaped groove 21 of the wire clamp body 2. Two wire clamping holes 200 for clamping a wire are formed between the first pressing blocks 3, the second pressing blocks 4 and the wire clamp body 2. A wedge block 5 is slidably disposed in the C-shaped groove 21 corresponding to between the first pressing block 3 and the second pressing block 4. A locking bolt 6 for driving the wedge block 5 to move along the axial direction of the C-shaped groove 21 is disposed on the locking housing 1. The wedge block 5 moves with the locking bolt 6 and drives the first pressing block 3 and the second pressing block 4 to move along the radial direction of the C-shaped groove 21. By adding a wedge block between the first pressing block and the second pressing block, by rotating the locking bolt, the locking bolt drives the first pressing block and the second pressing block to move radially in the C-shaped groove through the wedge block, so as to realize the adjustment of the size of the wire clamping hole of the wire clamp, achieve the purpose of using across wire diameters, and have a wider range of use. And by driving the wedge block with the locking bolt to press the wire tightly with the first pressing block and the second pressing block, it is more convenient to use, and the holding reliability of the wire clamp for the wire can be ensured, the connection between the wire and the wire clamp can be ensured to be more reliable, and it is beneficial to enhance the electrical conductivity. When adjusting the size of the wire clamping hole, rotate the locking bolt, the locking bolt drives the wedge block to slide axially along the C-shaped groove, and the wedge block pushes the first pressing block and the second pressing block to slide radially in the C-shaped groove, so as to realize the adjustment of the size of the wire clamping hole of the wire diameter.
[0026] As Figure 3 and4 As shown in the figure, two driving inclined surfaces 51 that cooperate with the first pressing block 3 and the second pressing block 4 are provided on both sides of the wedge block 5, and bearing inclined surfaces 201 that abut against the driving inclined surfaces 51 are respectively provided on the first pressing block 3 and the second pressing block 4. The wedge block drives the first pressing block and the second pressing block to slide through the driving inclined surfaces, thereby realizing stepless adjustment of the wire clamping holes, ensuring that the first pressing block and the second pressing block can reliably clamp the wire, and the connection reliability is higher. The width of the wedge block 5 gradually becomes narrower from the locking bolt 6 towards the first pressing block 3 and the second pressing block 4. The width of the first pressing block 3 is greater than the width of the second pressing block 3. The widths of the first pressing block and the second pressing block are designed to be different, so that the sizes of the two wire clamping holes are different, and thus the two wire clamping holes can clamp wires with different diameters.

One end of the locking bolt 6 passes through the threaded hole 111 and abuts against one end of the wedge block 5. The locking housing is connected to the locking bolt through the support portion, facilitating the assembly of the locking bolt and the locking housing, and the assembly is more convenient. The other end of the locking housing 1 has two symmetrically distributed limiting portions 12, and the two limiting portions 12 respectively abut against the ends of the first pressing block 3 and the second pressing block 4 away from the locking bolt 6. The two limiting portions of the locking housing play a limiting role on the first pressing block and the second pressing block, preventing the first pressing block and the second pressing block from sliding out of the wire clamp body. A receiving space 100 is formed between the support portion 11 and the two limiting portions 12, and the wire clamp body 2 is placed in the receiving space 100. The wire clamp body is placed between the support portion and the limiting portion, facilitating the assembly of the wire clamp body and the locking housing, and the assembly is more convenient.
[0028] As Figure 2 and 3 As shown in FIGS., arc-shaped pressing grooves 202 that cooperate with the wire clamp body 2 are respectively provided on the first pressing block 3 and the second pressing block 4, and the wire clamping holes 200 are formed between the arc-shaped pressing grooves 202 and the wire clamp body 2. The first pressing block and the second pressing block press the wire through the arc-shaped pressing grooves, ensuring the holding force of the wire clamp on the wire, and the connection reliability is higher. A plurality of anti-slip grooves 203 are provided in the arc-shaped pressing grooves 202. The anti-slip grooves play an anti-slip role on the wire, ensuring a more secure connection between the wire clamp and the wire. Guide inclined surfaces 204 that cooperate with the wire clamp body 2 are respectively provided on both sides of the arc-shaped pressing grooves 202 of the first pressing block 3 and the second pressing block 4. The guide inclined surfaces can play a guiding role, ensuring that the first pressing block and the second pressing block can move reliably in the C-shaped groove of the wire clamp body, facilitating the adjustment of the size of the wire clamping hole for the wire diameter.
