[0016] The technical solution of the present utility model will be clearly and completely described below through specific embodiments.

[0017] As Figure 1-2 shown, an integrated horse head for a wire fishing unit includes a horse head main body 1, a fishing head 1-1, a clamping surface 1-2, a pin hole 1-3, a pressing mechanism 2, a hexagonal clamping block 2-1, a glue injection hole 2-1, a sealing end cover 3, a gland head 4, a first pressing block 5, a second pressing block 6, and an adjusting gasket 7.

[0018] The upper end of the horse head main body 1 is designed as the structure of the fishing head 1-1, which is convenient for quickly fishing after the working barrel falls into the well; a clamping surface 1-2 is formed on the outer wall of the upper part of the horse head main body 1, which is convenient for on-site rapid assembly construction operations; a circle of pin holes 1-3 is arranged at the lower part of the horse head main body 1.

[0019] The upper part of the pressing mechanism 2 is embedded in the horse head main body 1, and the pressing mechanism 2 is matched with the horse head main body 1 through threads. An anti-backlash groove is provided at the position corresponding to the pin hole 1-3 of the horse head main body on the outer wall of the pressing mechanism 2, and the installation of a pin prevents the equipment from backlashing. The pressing mechanism 2 is also provided with a hexagonal clamping block 2-1, and the hexagonal clamping block 2-1 is located outside the horse head main body 1. The setting of the hexagonal clamping block 2-1 is convenient for on-site rapid assembly construction operations.

[0020] An adjusting gasket 7, a first pressing block 5, and a second pressing block 6 are arranged inside the cavity formed by the pressing mechanism 2 and the horse head main body 1. Both the first pressing block 5 and the second pressing block 6 are conical, and the second pressing block 6 is embedded in the first pressing block 5. By passing the cable core through the middle hole of the equipment and peeling the outer steel wire and placing it between the first pressing block 5 and the second pressing block 6, the cable pulling function of the horse head is completed.

[0021] A glue injection hole 2-1 and an observation hole are formed on the lower side wall of the pressing mechanism 2. After the assembly is completed, glue is injected into the glue injection hole 2-1 to complete the glue sealing protection of the cable core.
