The driving connecting rod 30 is arranged in the cap 10 in a penetrating way and can move relative to the cap 10; the embedded connecting rod 40 is arranged in the locking cap 20 in a penetrating way and can move relative to the locking cap 20.
The embedded connecting rod 40 is used for being inserted into the cable joint, at least one screw 50 is arranged on one end face of the embedded connecting rod facing the cable joint, and the screw 50 is embedded into a lead sealing gasket in the cable joint through rotation to connect the embedded connecting rod 40 with the lead sealing gasket. The embedded connecting rod 40 is connected with the driving connecting rod 30, moves along with the driving connecting rod 30 and enters and exits the cable joint, and the lead sealing gasket in the cable joint is taken out.
The cap 10 and the locking cap 20 may be an integral structure or may be connected together by a fixing screw 60 or the like to form a support body of the entire device. The cap 10 and the locking cap 20 are connected by the fixing screw 60, so that the cap and the locking cap can be detached, and the maintenance, the part replacement and the like of the whole device are facilitated. The outer circumference of the cap 10 may be circular or polygonal, the outer circumference of the locking cap 20 may be corresponding to the cap 10, and the outer circumferences of the two may be flush.
The cap 10 is provided with a central through hole 100 penetrating through opposite sides thereof for driving the connecting rod 30 to movably penetrate therethrough. The central bore 100 may further include a first bore section 101 and a second bore section 102 that are axially connected, the bore diameter of the first bore section 101 is larger than that of the second bore section 102, and a transition surface 103 between the first bore section 101 and the second bore section 102 may be a slope or a plane perpendicular to the axial direction of the cap 10. The first hole section 101 is located in one end of the cap 10 close to the locking cap 20, and the second hole section 102 is located in the other end of the cap 10 facing away from the locking cap 20.
The locking cap 20 is provided with a cap hole 200 for inserting the connecting rod 40 to movably penetrate therethrough. The cap hole 200 is in opposite communication with the central through hole 100 of the cap 10; specifically, the central through-hole 100 communicates with the cap hole 200 via its first hole section 101.
The locking cap 20 may further include a cover plate 21, and a cylinder 22 vertically coupled to one surface of the cover plate 21. The locking cap 20 is connected with the cap 10 through a cover plate 21 and is matched with the periphery of the cable connector through a cylinder 22; the cap hole 200 is provided on the cover plate 21 and communicates with the inside of the cylinder 22.

In order to prevent the driving connecting rod 30 from moving too much in the axial direction to be separated from the first hole section 101 and enter the second hole section 102, a first limiting step 31 protruding in the radial direction is arranged on the periphery of the first end of the driving connecting rod 30, and the outer diameter of the first limiting step 31 is larger than the inner diameter of the second hole section 102 and smaller than the inner diameter of the first hole section 101. During the axial displacement of the drive rod 30, the first limit step 31 can come into detachable abutment against the transition surface 103 between the first bore section 101 and the second bore section 102. When the first limit step 31 abuts against the transition surface 103, the drive link 30 is restricted from further moving toward the second hole section 102.
In order to facilitate the operation of the driving connecting rod 30 to rotate in the forward direction or the reverse direction, the lead sealing gasket screwing and taking device of the invention further comprises a driving cap 70.

In order to prevent the embedded connecting rod 40 from moving too much to be separated from the first hole section 101, the periphery of the second end of the embedded connecting rod 40 is provided with a second limiting step 41 protruding in the radial direction, and the outer diameter of the second limiting step 41 is larger than the inner diameter of the cap hole 200 and smaller than the inner diameter of the first hole section 101. During the axial movement of the tie-in rod 40, the second limit step 41 can come into detachable abutment against the surface of the locking cap 20 facing the over-cap 10. When the second limit step 41 abuts on the surface of the locking cap 20 facing the cap 10, the embedded link 40 is restricted from moving further toward the cylinder 22.
The screw 50 is disposed on the end face of the first end of the embedded connecting rod 40, and when the embedded connecting rod 30 rotates and moves into the cable connector, the screw 50 can rotate with the embedded connecting rod 40 and screw into the lead sealing gasket to connect the lead sealing gasket with the embedded connecting rod 40.
For a ring-shaped lead sealing gasket, the outer diameter of the screw 50 should be smaller than the ring width of the lead sealing gasket. Preferably, two or more screws 50 are provided to stably connect the lead seal gasket to the insertion link 40 after the lead seal gasket is inserted, thereby preventing the lead seal gasket from being inclined or falling off during the insertion.
According to the setting requirement, the embedded connecting rod 40 and the driving connecting rod 30 can be fixedly connected into a whole or detachably connected through welding and other modes. Preferably, the embedded link 40 is detachably connected to the driving link 30, so that one of the embedded link and the driving link can be replaced conveniently.
In the embodiment shown in fig. 3, the first end of the drive link 30 is provided with a protruding connecting rod 32, and the connecting rod 32 is axially connected to the first end of the drive link 30.
