[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This is an integrated hydraulic amp wire clamp installation tool. The tool head and the complete set of screw rods can be used to tighten and clamp the external steel core wire with the cooperation of the hydraulic sleeve and the electric cylinder. Traditionally, there are split hydraulic amp wire clamp guns on the market, which are composed of a hydraulic pipe connecting the hydraulic part and the crimping part. The overall use process generally requires two people to cooperate in operation, which is cumbersome and inconvenient to store. When the overall device on the tool head is used to connect the steel core wire, it does not need to be assisted by the traditional ammunition-type drive and grip handle, and can be used alone by hand. In terms of performance, the overall device on the tool head can meet the requirements of installing sealed 1000V distribution lines, thereby achieving an integrated hydraulic drive, which is convenient for one person to operate alone and is simple and convenient to operate, as well as the effect of a subsequent overall storage cabinet.

[0016] (2) An integrated hydraulic AMP wire clamp installation tool, wherein a limiting protective sleeve is installed inside the installation end, and the striker itself is arranged in the limiting protective sleeve and is movably connected with the inside of the limiting protective sleeve. When a traditional striker is squeezed for a long time, the striker itself is prone to deformation and bending, while the limiting protective sleeve inside the installation end can fit together with the outside of the striker. At this time, when the striker is used for normal sliding, the striker itself will not be deformed or bent under the protection of the limiting protective sleeve, thereby achieving the effect that the limiting protective sleeve can provide certain protection to the outside of the striker and extend the service life of the striker itself.

[0017] (3) This is an integrated hydraulic AMP wire clamp installation tool. When the striker itself is replaced after being used for a certain period of time, the striker can be squeezed into the interior of the screw rod until it is movably engaged with the slot in the rebound round part. At the same time, the striker is squeezed and pushed into the interior of the screw rod, so that the limiting slide slides in the limiting slide slot and squeezes the support spring. At this time, when the striker is released, the striker can be quickly ejected from the inside of the installation end under the elasticity of the support spring. The installation end can be removed from the inside of the installation screw slot to make the striker fall out, thereby achieving the effect of quickly disassembling the striker for replacement.

[0018] (4) This is an integrated hydraulic AMP wire clamp installation tool. The hydraulic sleeve itself can be threadedly sealed with the back end of the screw rod through the thread on the installation sealing tube, which can prevent the traditional split hydraulic pipe from being exposed to the outside connection. The internal hydraulic system of the hydraulic sleeve is completely covered inside the hydraulic sleeve itself, thereby achieving the effect of reducing the oil leakage caused by wear of the traditional hydraulic oil pipe.

[0029] In an embodiment of the present invention, a limiting protective sleeve 21 is coaxially fixed to the inner wall of the needle storage cavity at the mounting end. The limiting protective sleeve is a circular hollow sleeve. The outer wall of the firing pin and the inner wall of the limiting protective sleeve are movably engaged and limited. When the firing pin is in normal sliding use, the firing pin itself will not be deformed or bent under the protection of the limiting protective sleeve, thereby achieving the effect of enabling the limiting protective sleeve to provide certain protection to the outside of the firing pin and extending the service life of the firing pin itself.

[0030] In the embodiment of the present invention, a rebound circular piece 22 cooperating with the tail end of the striker is arranged inside the complete set of screw rods, and two groups of mirror-distributed limiting slides 25 are fixedly arranged on the outer wall of the rebound circular piece. Limiting slide grooves 24 are provided at the positions of the inner wall of the inner cavity corresponding to the two groups of limiting slides. The limiting slide grooves are rectangular hollow groove-shaped and extend toward the side away from the striker. The limiting slide is connected to the inside of the limiting slide groove by sliding.

[0031] In an embodiment of the present invention, when the firing pin itself needs to be replaced after being used for a certain period of time, the firing pin can be squeezed into the interior of the complete screw set until it is movably engaged with the slot in the rebound circular piece. At the same time, the firing pin is squeezed and pushed into the interior of the complete screw set, so that the limiting slide slides in the limiting slide slot and squeezes the supporting spring. At this time, when the firing pin is released, the firing pin can be quickly popped out from the inside of the mounting end under the elasticity of the supporting spring, and the mounting end can be removed from the inside of the mounting screw slot to pour out the firing pin, thereby achieving the effect of quickly disassembling the firing pin for replacement and use.

[0032] In the embodiment of the present invention, a slot 23 for limiting the striker is coaxially formed on one side of the rebounding circular member close to the striker, and a tail pin 27 is abutted against the tail end of the striker and penetrates the rebounding circular member through the tail pin to connect with the telescopic push rod.

[0033] In the embodiment of the present invention, a push block 14 is fixedly connected to the end of the telescopic push rod and is coaxially fixedly connected to the end of the tail pin via the push block.

[0035] In the embodiment of the present invention, a wire clamp 19 for inserting the external steel core wire is disposed outside the tool head, and a wedge 20 is disposed inside the wire clamp for clamping and fastening the external steel core wire.

[0036] A working method of an integrated hydraulic AMP wire clamp installation tool is performed in the following steps: when in use, the installation sealing tube on the hydraulic sleeve is initially screwed and fixed with the internal thread on the rear side of the entire screw set, and does not need to be disassembled for subsequent use. When in use, the external steel core wire is inserted into the clamping grooves on both sides of the wire clamp piece, and the wedge block is inserted between the two sets of steel core wires, so that the wire clamp piece is placed in a recessed position inside the tool head, and the installation ribs on the installation end are threadedly assembled with the installation screw groove inside the tool head so that one end of the installation end is fitted and docked with the rear end of the wedge block. After the electric cylinder is started, the expansion and contraction inside the hydraulic sleeve can be controlled by the circuit cooperation between the driving button itself and the electric cylinder. The push rod is hydraulically driven to drive and squeeze the tail end of the striker, and the head end of the striker close to the wedge block will move and contact the wedge block when driven, so that the wedge block moves to a smaller opening inside the wire clamp, thereby increasing the clamping tightness between the two groups of steel core wires inside the wire clamp. In this way, when the overall device on the tool head is used to connect the steel core wire, there is no need for the traditional ammunition-type drive and grip handle to assist in hand-held use, and the performance of the overall device on the tool head can meet the requirements of installing sealed 10kV distribution lines, so that it can be used for integrated hydraulic drive, which is convenient for one person to operate alone, and the operation is simple and convenient, as well as the subsequent overall storage cabinet.
