Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 8 The utility model provides a technical solution: a line insulation protection sleeve, comprising a fixed chuck body 1, a cover plate 2 hinged on the top of the fixed chuck body 1, and an insulation protection sleeve 3 installed between the fixed chuck body 1 and the cover plate 2. An upper slider 11 is movably installed inside the fixed chuck body 1, and a lower slider 15 is slidably connected inside the upper slider 11. A cylinder 12 is arranged inside the lower slider 15, and a spring 14 is sleeved on the outer side of the cylinder 12. The spring 14 is used to apply a thrust to the lower slider 15 and the upper slider 11. When the key 7 is pulled out, the upper slider 11 and the lower slider 15 are no longer restricted. One end of the spring 14 applies a thrust downward to the lower slider 15, and the other end applies a thrust upward to the upper slider 11. Due to the restriction of the inclined block 19 and the inclined groove 17, the upper slider 11 moves along The inclined groove 17 moves obliquely upward, and the upper slider 11 drives the lower protrusion 10 to move. The lower protrusion 10 cooperates with the upper protrusion 9 to clamp the cable, so that the cover plate 2 and the fixed clamp body 1 are fixed to the outside of the cable by using the spring 14. There is no need to use screws to fix, so as to avoid vibration causing the screws to loosen, making the fixation unstable, and the installation steps are convenient. A key 7 is inserted at the bottom of the cylinder 12, and the key 7 is used to limit the lower slider 15 and the upper slider 11. When the key 7 is inserted into the cylinder 12, the lower slider 15 and the upper slider 11 cannot move. A trapezoidal protrusion 16 is provided on the inner side wall of the fixed clamp body 1, and an inclined groove 17 is provided on the trapezoidal protrusion 16. The outer side of the upper slider 11 is integrally formed with an inclined block 19 slidably connected to the inclined groove 17, and the inclined block 19 cooperates with the inclined groove 17 to guide the movement direction of the upper slider 11.

[0024] A through hole 20 is formed through the bottom of the fixing chuck body 1 , and the through hole 20 facilitates the key 7 to pass through the fixing chuck body 1 and be inserted into the cylinder 12 .

[0025] Among them, a limiting groove 21 is provided on the outer side of the lower slider 15, and a limiting block 13 slidably connected to the limiting groove 21 is provided on the inner wall of the upper slider 11. The limiting block 13 cooperates with the limiting groove 21 to limit the lower slider 15, so that the lower slider 15 is more stable during movement.

[0026] A stopper 18 is disposed on the outer side of the upper slider 11 , and the stopper 18 contacts the top of the trapezoidal protrusion 16 , so that the upper slider 11 is more stable when moving.

[0027] Among them, a lower protrusion 10 is provided on the top of the upper slider 11, and an upper protrusion 9 is provided on the bottom of the cover plate 2. The lower protrusion 10 and the upper protrusion 9 are used to increase the friction with the circuit, so that the fixing clamp body 1 and the cover plate 2 can clamp the circuit more firmly.

[0028] A lock buckle 4 is installed on one side of the cover plate 2 , and a locking block 5 matching with the lock buckle 4 is provided on the outer side of the fixing clamp body 1 . The lock buckle 4 and the locking block 5 cooperate to fix one side of the cover plate 2 on the fixing clamp body 1 .

[0029] Among them, the inner sides of the cover plate 2 and the fixed clamp body 1 are both provided with positioning blocks 6, and the insulating protective sleeve 3 is provided with positioning grooves 8 that cooperate with the positioning blocks 6. The positioning blocks 6 and the positioning grooves 8 cooperate to limit the insulating protective sleeve 3 to prevent the insulating protective sleeve 3 from moving between the fixed clamp body 1 or the cover plate 2.

[0030] Specifically, first install the insulating protective sleeve 3 on the cable, then take the fixed clamp body 1, open the cover 2, align the positioning block 6 with the positioning groove 8, close the cover 2, and lock the cover 2 through the lock buckle 4 and the lock block 5, so that the positioning block 6 is inserted into the positioning groove 8, and the cover 2 and the fixed clamp body 1 are clamped on the outside of the insulating protective sleeve 3, and then pull out the key 7, the upper slider 11 and the lower slider 15 are no longer restricted, one end of the spring 14 applies a thrust downward to the lower slider 15, and the other end applies a thrust upward to the upper slider 11, due to the limiting effect of the inclined block 19 and the inclined groove 17, the upper slider 11 moves obliquely upward along the inclined groove 17, the upper slider 11 drives the lower protrusion 10 to move, and the lower protrusion 10 cooperates with the upper protrusion 9 to clamp the cable.
