[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1, reference Figure 1 - Figure 2 , which is the first embodiment of the present invention, provides a tool for fixing a bypass cable access conductor, including an installation unit 100, including a main pole 101 and an extension pole 102, and a telescopic component 103 arranged between the main pole 101 and the extension pole 102; a lifting unit 200, including a hook 201 and a supporting hook 202, a connecting component 204 arranged on the end of the extension pole 102 and connected to the hook 201, and an adjusting component 205 arranged on the outside of the extension pole 102 and connected to the supporting hook 202.

[0029] Furthermore, it is proposed to use a 4M long main rod 101 as the main body of the device, with a pressure resistance level of 10Kv and made of epoxy resin, and design an extension rod 102, and realize the operation of the tool by telescoping or rotating the extension rod 102. Through the telescopic component 103, it can adapt to different heights and distances.

[0030] The connecting sleeve 103a is fixedly sleeved on the outer wall of the extension rod 102 near the lower end by bolts, and the telescopic rod 103b is fixedly sleeved on the outer wall of the main rod 101 near the upper end by bolts. This fixing method ensures the connection strength and stability between the telescopic assembly 103 and the main rod 101 and the extension rod 102, and can improve the flexibility of the device when used. The extension rods 102 of different lengths can be quickly replaced to lift cables of different heights. The telescopic rod 103b is connected to the inner side of one end of the connecting sleeve 103a by threads. The threaded connection allows the telescopic rod 103b to be telescoped inside the connecting sleeve 103a.

[0031] Example 2, reference Figure 3 - Figure 4, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: further, the threaded rod 201a is connected to the lower end of the hook 201 by threading, and the threaded connection allows the threaded rod 201a to move up and down inside the hook 201 to adapt to different clamping requirements, the clamping block 201b is located above the threaded rod 201a, and is used to clamp objects, the special-shaped block 201c presents a "T"-shaped cylindrical structure, and is arranged at the end of the threaded rod 201a, and the bottom of the clamping block 201b is threadedly connected with two groups of limit plates 201d, and the two groups of limit plates 201d are used to limit the position of the special-shaped block 201c, and the rotation groove 201e is a circular hole-shaped groove arranged at the bottom of the clamping block 201b, and is located between the two groups of limit plates 201d. The rotation groove 201e is used to accommodate the special-shaped block 201c and allow it to rotate in the groove;

[0032] After the upper end of the special-shaped block 201c is limited in the rotation groove 201e, the two groups of limiting plates 201d are threadedly connected to the bottom of the clamping block 201b by bolts. The distance between the two groups of limiting plates 201d is smaller than the diameter of the circular hole of the rotation groove 201e, which makes the diameter of the upper end of the special-shaped block 201c larger than the diameter between the two groups of limiting plates 201d. This makes the position of the special-shaped block 201c limited by the two groups of limiting plates 201d at this time, allowing the special-shaped block 201c to rotate freely in the groove, but at the same time it is limited in the rotation groove 201e by the two groups of limiting plates 201d, and the position of the special-shaped block 201c is fixed, thereby achieving the effect of rotatably connecting the threaded rod 201a and the clamping block 201b together. This connection method allows the threaded rod 201a to rotate in the clamping block 201b while maintaining the stability of its position.

[0033] Among them, the upper part of the clamping block 201b is designed to be a downwardly concave arc surface, which can increase the contact area with the cable and provide a more uniform clamping force. The upper inner wall of the hook 201 is also designed to be an arc surface, corresponding to the arc surface of the clamping block 201b. When the upper arc surface of the clamping block 201b is opposite to the upper inner wall of the hook 201, they together form a variable elliptical structure. This structure can make the hook 201 adapt to cables of different diameters. The relative position between the clamping block 201b and the hook 201 can be adjusted by rotating the threaded rod 201a, and the size of the elliptical structure can be changed to adapt to cables of different diameters. The arc surface design helps to distribute the clamping force more evenly during the clamping process, reduce the local pressure on the cable, and avoid damaging the cable. The variable elliptical structure provides good adaptability, so that the same hook 201 can be used for cables of multiple different diameters, increasing the versatility and practicality of the tool. The user can easily adjust the position of the clamping block 201b according to the diameter of the cable to be clamped, so as to achieve rapid clamping.

[0034] Furthermore, the fixing sleeve 204a is used to be sleeved on the outside of the connecting block 204b to fix and protect the connecting block 204b. The connecting block 204b is arranged at the other end of the threaded rod 201a. The connecting block 204b cooperates with the fixing sleeve 204a to jointly realize the connection with the extension rod 102. One end of the extension rod 102 is designed to be hollow so that the fixing sleeve 204a can be plugged and connected inside one end of the extension rod 102. Several groups of connecting holes 204c are opened on the outside of the extension rod 102. These holes are used to align with the through holes 204d on the fixing sleeve 204a and the connecting block 204b so as to realize fixed connection by bolts. A through hole 204d is provided on the central axis of the fixing sleeve 204a and the connecting block 204b. This hole is used to align with the connecting hole 204c on the extension rod 102 so as to realize fixed connection by bolts. The fixing sleeve 204a and the connecting block 204b are connected to the through holes 204d and the connecting holes 204c in sequence by bolts to realize fixed connection with the extension rod 102.

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 3, reference Figure 5 - Figure 6 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

[0037] One end of the second threaded rod 202a is threadedly connected to the upper end of the hook 201, and the other end of the second threaded rod 202a is provided with a connecting piece 202d. A cylindrical hole 202c is provided on the upper surface of the fixed block 202b, and the connecting piece 202d is inserted into the cylindrical hole 202c of the fixed block 202b to realize the connection between the second threaded rod 202a and the fixed block 202b.

[0038] Furthermore, the limiting holes 203a are arranged on the front side of the fixing block 202b, and the limiting holes 203a are arranged in two groups, which are mirrored on both sides of the cylindrical hole 202c with the central axis of the fixing block 202b. The two groups of limiting holes 203a are threadedly connected with fixing pins 203b, and the two groups of limiting holes 203a are connected to the cylindrical hole 202c. The connecting piece 202d is cylindrical, and its two sides are curved, forming a complete circular hole with the limiting hole 203a, and the fixing pin 203b is connected together, so that when the connecting piece 202d is inserted into the inner hole of the cylindrical hole 202c, The fixing pin 203b is threadedly connected in the limiting hole 203a to limit the position of the connecting piece 202d at this time, so as to achieve the effect of fixing the threaded rod 202a and the fixing block 202b together, and an anti-loosening washer 203c is provided on the outer cover of the connecting piece 202d. The use of the anti-loosening washer 203c effectively prevents the problem of thread loosening caused by long-term use. The silicone anti-slip sleeve 202e is sleeved on the other end of the threaded rod 1 201a to increase the anti-slip performance when holding. The silicone anti-slip sleeve 202e increases the safety during operation and prevents accidents caused by slipping.

[0039] Among them, the lower part of the fixed block 202b is designed to be a downwardly concave arc surface, which can increase the contact area with the cable and provide a more uniform clamping force. The upper inner wall of the hook 202 is also designed to be an arc surface, corresponding to the arc surface of the fixed block 202b. When the lower arc surface of the fixed block 202b is opposite to the lower inner wall of the hook 202, they together form a variable elliptical structure. This structure allows the support hook 202 to adapt to cables of different diameters. The relative position between the fixed block 202b and the support hook 202 can be adjusted by rotating the threaded rod 202a, and the size of the elliptical structure can be changed to adapt to cables of different diameters. The arc surface design helps to distribute the clamping force more evenly during the clamping process, reduce local pressure on the cable, and avoid damaging the cable. The variable elliptical structure provides good adaptability, so that the same support hook 202 can be used for cables of various diameters, increasing the versatility and practicality of the tool. The user can easily adjust the position of the fixed block 202b according to the diameter of the cable to be clamped, thereby achieving quick clamping. The lower arc surface of the fixed block 202b and the lower inner wall of the support hook 202 are both serrated, which can improve stability during clamping.

[0040] Furthermore, the fixing member 205a is arranged outside the hook 202, presenting a hollow structure, so that the fixing member 205a is sleeved on the outside of the extension rod 102. The hollow structure design of the fixing member 205a enables it to adapt to extension rods 102 of different sizes, increasing the versatility and adaptability of the adjustment component 205. The outer wall of the fixing member 205a is provided with fixing holes 205b, which are used for bolts to pass through, so as to achieve a fixed connection between the fixing member 205a and the extension rod 102. The fixing member 205a is fixedly connected to the extension rod 102 by passing the bolts through the fixing holes 205b, the connecting holes 204c and the extension rod 102. This connection method is simple and effective, and can provide a stable connection. The design of the fixing member 205a being sleeved on the outside of the extension rod 102 allows the user to adjust the position of the hook 202 as needed, providing flexibility and adjustability.

[0041] The remaining structure is the same as that of Example 2.
