In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1, reference Figures 1 to 7, which is the first embodiment of the present invention, provides a wall bushing live insulation wrapping device, including a hand-held mechanism 100, including an operating rod 101 and a first connecting component 102, the first connecting component 102 divides the operating rod 101 into an upper rod 101a and a lower rod 101b, the outer wall of the lower rod 101b is sleeved with a handle 101c, and the handle 101c is made of insulating material; an opening and closing mechanism 200, which is arranged at the end of the upper rod 101a of the operating rod 101, and includes a thermal The heat shrink sleeve 201, the second connecting component 202, the clamping component 203 and the locking component 204, the clamping component 203 and the locking component 204 cooperate to wrap the heat shrink sleeve 201 on the outer wall of the wall-penetrating pipe; the fixing mechanism 300, the fixing mechanism 300 is used to heat the heat shrink sleeve 201 so that the heat shrink sleeve 201 is wrapped on the outer wall of the wall-penetrating pipe, the fixing mechanism 300 includes a hand-held rod 301 and a hot air gun 302, and the hot air gun 302 is arranged at the end of the hand-held rod 301.

[0038] Specifically, the first connecting component 102 includes a connecting shell 102a, a first fixing pin 102b, a first connecting block 102c and a toggle block 102d. The connecting shell 102a is used to connect the upper rod 101a and the lower rod 101b of the operating rod 101. The first fixing pin 102b passes through the first connecting block 102c and the toggle block 102d at the same time and fixes the first connecting block 102c and the toggle block 102d on the connecting shell 102a.

[0039] Furthermore, the second connecting component 202 includes an inner rod 202a, a second fixing pin 202b and a guide rod 202c, the inner rod 202a is arranged on the inner wall of the upper rod 101a of the operating rod 101, one end of the inner rod 202a is fixedly connected to the end of the first connecting block 102c, the other end of the inner rod 202a is fixedly connected to the end of the guide rod 202c, and the second fixing pin 202b passes through the guide rod 202c.

[0040] It should be noted that the operating rod 101 is made of insulating material, and is divided into two separate parts, which are connected together under the action of the connecting shell 102a. The upper rod 101a of the operating rod 101 is sleeved on the outside of the inner rod 202a. When the operator presses the toggle block 102d, the inner rod 202a will move accordingly but the operating rod 101 will not, thereby ensuring the stability of the device. The lower end of the lower rod 101b of the operating rod 101 is sleeved on the handle 101c, which is convenient for the operator to hold and operate and improves safety. The upper end of the lower rod 101b is sleeved on the connecting shell 102a of the first connecting component 102, and the position design of the claw clamping the end of the second connecting component 202 is ergonomic, which is convenient for the operator to press the control block. The lower end of the upper rod 101a of the operating rod 101 is sleeved with the connecting shell 102a, and the upper end is sleeved with the guide rod 202c. By moving the toggle block 102d upward or downward, the inner rod 202a and the guide rod 202c are driven to move up and down, thereby controlling the tightness of the claw clamp, making it easier to put the heat shrink sleeve 201 on the wall pipe.

[0041] Example 2, reference Figures 3 to 7 This embodiment is different from the first embodiment in that: the clamping component 203 includes a clamping frame 203a and a clamping claw 203b, the clamping frame 203a is fixedly connected to the end of the upper rod 101a of the operating rod 101, both ends of the second fixed pin 202b are movably connected to the inner wall of the clamping frame 203a, a return spring is fixedly connected to the inner wall of the guide rod 202c, and the other end of the return spring is fixedly connected to the inner wall of the clamping frame 203a, and the clamping claw 203b is provided with two groups symmetrically on the left and right, and the clamping claw 203b is connected to both sides of the clamping frame 203a by bolts.

[0042] Specifically, the locking component 204 includes a connecting piece 204a, a limiting piece 204b and a plug-in piece 204c. The connecting piece 204a is used to connect the limiting piece 204b and the plug-in piece 204c with the clamping jaw 203b, and the plug-in piece 204c is used to connect the clamping jaws 203b on both sides together.

[0043] The connecting member 204a includes a slide rail 204a-1 and a connector 204a-2. The connector 204a-2 is connected to the end of the slide rail 204a-1, and the connector 204a-2 is arranged at the end of the clamping claw 203b.

[0044] Furthermore, a circular hole is provided on the side wall of the connector 204a-2, and an insulating rope passes through the circular hole. One end of the insulating rope away from the circular hole naturally hangs down to the handle 101c due to gravity.

[0045] It should be noted that the lower end of the connecting shell 102a is sleeved on the lower part of the operating rod 101, and the upper end is sleeved on the upper part of the operating rod 101, so that the two parts of the operating rod 101 are connected. Under the action of the first fixed pin 102b, the toggle block 102d and the first connecting block 102c are vertically assembled together. When the operator toggles the toggle block 102d, the first connecting block 102c can move up and down. When the operator toggles the control block upward, the first connecting block 102c will move downward, thereby driving the inner rod 202a to move downward. The upper end of the inner rod 202a is fixedly connected to the lower end of the guide rod 202c. When the inner rod 202a moves downward, it will drive the guide rod 202c to move accordingly. The upper end of the guide rod 202c is connected to the claw clamp frame through the second fixed pin 202b. When the guide rod 202c moves downward, it drives the second fixed pin 202b to move downward together, thereby clamping the claw 203b of the claw clamp to reduce the grasping range.

[0046] The rest of the structure is the same as that of Example 1.

The outer diameter of the fixed pin 204c-4 is slightly smaller than the inner diameter of the epoxy tube clamp 204c-3. The epoxy tube clamp 204c-3 can move along the fixed pin 204c-4.

[0049] It should be noted that the outer diameter of the slide rail 204a-1 matches the inner diameter of the guide rail fixing, and is sleeved in the guide rail fixing seat 204b-2. The main part of the connector 204a-2 is designed as a hollow cylinder, which is sleeved on the slide rail 204a-1. The connecting part of the connector 204a-2 and the pipe buckle 204c-2 are connected together by a snap block under the action of screws. A round hole is set at the end of the connector 204a-2 close to the guide rail fixing, and the round hole is used to bolt an insulating rope, such as Figure 6 As shown, one end of the insulating rope is bolted to the round hole of the connector 204a-2, and the other end passes through the round ring fixed on the guide rail and then naturally hangs down along the claw clamp and the claw clamp frame. The operator can control the sliding of the connector 204a-2, the pipe clamp, the epoxy pipe clamp 204c-3, and the pin by pulling the insulating rope on the ground;

[0050] The slide rail 204a-1 is a cylindrical structure with a groove. The width of the groove matches the diameter of the fixed pin 204c-4. A fixed block 204b-1 is installed on the end that is not fixed to the guide rail. The fixed block 204b-1 and the guide rail are fixed to prevent falling off during sliding. The tube clamp is designed in a semicircular shape, and the inner diameter of the arc is slightly larger than the outer diameter of the epoxy tube clamp 204c-3. The tube buckle 204c-2 is sleeved on the epoxy tube clamp 204c-3, and the tube clamp and the epoxy tube clamp 204c-3 are fixed together by the movement of the fixing pin 204c-4. The length of the pin is the distance from the bottom of the groove of the slide rail 204a-1 to the inner diameter of the tube clamp, and a spring is installed inside it. The claw clamp is connected to the claw clamp frame through the second fixing pin 202b. The two clamping claws 203b of the claw clamp are equipped with clamping blocks 204c-1, which are used to fix the heat shrink sleeve 201 on the claw clamp and prevent damage to the heat shrink sleeve 201.

[0051] The rest of the structure is the same as that of Example 2.

[0052] Example 4, reference Figures 10 to 13 This embodiment is different from the above embodiments in that a switch 302a for controlling the start and stop state of the hot air gun 302 is provided on the handheld rod 301, and a signal transmitter 302b and a signal receiver 302c are provided between the switch 302a and the hot air gun 302.
