Preferably, the upper wire clamp and the limiting block are of an integral structure, the limiting block is arranged in the upper clamping plate, a groove is formed in the upper end of the limiting block corresponding to the fixing hole, and the limiting block is used for stretching the upper wire clamp.

Preferably, the screw rod of bolt only has and is equipped with the screw thread more than the middle part, when the stopper is flexible from top to bottom according to different specification cables, the recess on the stopper will be withstood to the shank of bolt portion of different length, and the screw thread on the bolt middle part will agree with through the fixed orifices and fix in the punch holder, because the ascending power of stopper has the thread tightening down, and then stablizes the centre gripping cable.

Preferably, go up the fastener and be the camber with lower fastener, and go up the fastener and be equipped with 5 mm's rib with lower fastener's camber surface, it is greater than lower fastener to go up the fastener size.

Preferably, the slotted hole corresponds to the two ends of the arc surface of the lower wire clamp, and the two ends of the lower wire clamp can penetrate through the slotted hole, so that the upper wire clamp and the lower wire clamp are overlapped, the diameter between the upper wire clamp and the lower wire clamp is reduced, and the cable clamp is suitable for cables with different sizes.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses go up the fastener and go down the mutual centre gripping of fastener and then improve the stability of cable installation, go up the fastener simultaneously and can stretch out and draw back according to different cable specifications between the fastener, and then improve the installation effectiveness.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the cable clamp comprises an upper clamp plate 1, a lower clamp plate 2, an upper cable clamp 5 and a lower cable clamp 8, wherein the upper clamp plate 1 is connected with the lower clamp plate 2 through a connecting block 3, four corners at the top end of the upper clamp plate 1 are provided with fixing holes 4, bolts 41 are arranged in the fixing holes 4, four upper cable clamps 5 are arranged at the lower end of the upper clamp plate 1 corresponding to the fixing holes 4, the top end of each upper cable clamp 5 is connected with a limiting block 6, the two ends of the cambered surface of each upper cable clamp 5 are provided with slotted holes 7, the upper end of the lower clamp plate 2 is provided with four lower cable clamps 8 corresponding to the upper cable clamps 5, the upper cable clamps 5 and the limiting blocks 6 are of an integral structure, the limiting blocks 6 are arranged in the upper clamp plate 1, the top ends of the limiting blocks 6 are provided with grooves corresponding to the fixing holes 4, the limiting blocks 6 are, the recess on the stopper 6 will be withstood to the 41 pole portions of bolt of different length, and the screw thread on the middle part of bolt 41 will agree with through fixed orifices 4 and fix in punch holder 1, because there is ascending power of stopper 6 down, go up the power that has the thread tightening, and then stabilize the centre gripping cable, it is the arc profile to go up fastener 5 and lower fastener 8, and the arc profile surface of going up fastener 5 and lower fastener 8 is equipped with 5 mm's rib, it is greater than lower fastener 8 to go up fastener 5 size, the rib on the arc profile surface of going up fastener 5 and lower fastener 8 is used for the increase friction, improves the stability of cable centre gripping, slotted hole 7 corresponds each other with 8 cambered surface both ends of lower fastener, 8 both ends of lower fastener can pass slotted hole 7, make and go up fastener 5 and lower fastener 8 coincidence, reduce the diameter between fastener 5 and the lower fastener 8, adapt to the cable of equidimension not.
