In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiment 1

[0026] Reference Figure 1 and Figure 2 The first embodiment of the present application provides a fixing mechanism which can achieve the effect of fixing and replacing insulators, which comprises a fixing piece 100, a limiting piece 200 and a connecting piece 300.

[0028] Further, the limiting piece 200 comprises a wedge block 201 and a threaded rod 202, one end of the threaded rod 202 is rotationally matched with the wedge block 201. The inner wall of the first clamp 101 and the second clamp 102 is provided with at least one groove 103, the wedge block 201 is matched with the groove 103 and one-to-one correspondence. The threaded rod 202 is respectively matched with the first clamp 101 and the second clamp 102 in screw thread. The inner wall of the first clamp 101 and the second clamp 102 is uniformly provided with four grooves 103, the wedge block 201 and the threaded rod 202 are provided with four, when the object in the containing space M can be subjected to uniform pressure from four different directions so that the fixing is more stable. The first clamp 101 and the second clamp 102 are provided with four through holes, the through holes are matched with the threaded rod 202 in screw thread. When the threaded rod 202 is screwed on the outside, it will move up and down along the direction of the threaded rod 202 and then press the object to different degrees, and when different sizes of insulators are encountered, it can be used flexibly.

[0029] Wherein, the two end faces of the wedge block 201 are respectively parallel to the two end faces of the first clamp 101 and the second clamp 102. The wedge block 201 is provided with a placing hole 201a, and the threaded rod 202 is rotationally matched with the placing hole 201a. The threaded rod 202 is rotationally matched with the wedge block 201 through the through hole of the first clamp 101 and the second clamp 102.

[0030] Wherein, the first clamp 101 and the second clamp 102 are respectively hinged with the connecting piece 300. The connecting piece 300 connects the two independent fixing pieces 100 so that the fixing piece 100 will move when the connecting rod is subjected to force.

[0031] In use, the hinged part of the first clamp 101 and the second clamp 102 of the two fixing pieces 100 is opened, placed outside the insulator, and then the first clamp 101 and the second clamp 102 are closed, the four threaded rods 202 are screwed into the through holes, and the four wedge blocks 201 are pressed on the insulator under the pushing of the threaded rods 202, and then the insulator is disassembled after being fixed.

[0032] Embodiment 2

[0033] Reference Figure 1 For the second embodiment of the utility model, different from the previous embodiment, the embodiment provides a fixing mechanism, solves the problem that the staff cannot judge the pressing force of the clamp and easily causes damage to the insulator, which comprises a fixing piece 100, a limiting piece 200 and a connecting piece 300.

[0034] Specifically, the connecting piece 300 comprises a screw rod 301 and a rocker 302, the rocker 302 is provided with two and is sleeved on the two screw rods 301 respectively. The extension direction of the rocker 302 is perpendicular to the screw rod 301 and is sleeved on the middle position of the screw rod 301, the two ends of the screw rod 301 are provided with opposite threads, when the rocker 302 shakes up and down (the connection position of the rocker 302 and the screw rod 301 can adopt the structure of a ratchet wrench, that is, one-way force), the screw rod 301 will be driven to rotate, since the screw rod 301 is provided with opposite threads, the fixed piece 100 fixedly connected with the two ends of the screw rod 301 will move in the opposite direction.

[0035] The rest of the structure is the same as that of example 1.

[0036] In use, when the screw rod 301 is tightened, the fixed pieces 100 at both ends will move inward at the same time, so that the insulator string is relaxed, the insulator to be replaced is disassembled, the new insulator is replaced, the screw rod 301 is loosened, the fixed pieces 100 will move outward at the same time, the insulator string is tensioned, so that the insulator string returns to the previous state, the hinged part of the first clamp 101 and the second clamp 102 is opened, the clamp is taken away, and the whole replacement process is completed.

[0037] Example 3

[0038] Reference Figure 3 The third embodiment of the utility model, different from the previous embodiment, provides an intelligent self-adaptive closed clamp, solves the problem that intelligentization cannot be realized, and comprises a control module 400, a signal sending unit 500, a display screen 600 and a force sensor 700.

[0039] Specifically, the control module 400 is arranged in the rocker 302, the signal sending unit 500 is fixedly arranged at one end of the screw rod 301, the display screen 600 is fixedly arranged at the other end of the screw rod 301, and the force sensor 700 is fixedly arranged at the end of the screw rod 301; the control module 400 is electrically connected with the signal sending unit 500, the display screen 600 and the force sensor 700 respectively.

[0040] The force sensor 700 detects the tension force borne by the fixture and converts the force into an electrical signal, and the control module 400 converts the electrical signal into a digital signal and transmits the digital signal to the display screen 600, so that the tension force value is displayed on the display screen 600, facilitating observation by the worker. According to the formula P = P1 x 0.25 + 5 (unit: KN), P1 is the weight of the insulator, and the working load required by the insulator can be calculated according to the formula. When the value exceeds this value, the fixture will cause damage to the insulator, so the worker can observe the value on the display screen 600 when up and down the rocker 302 to avoid exceeding or not reaching the force required to replace the insulator. The signal sending unit 500 transmits the digital signal to the app through wireless transmission, so that the worker can remotely understand the working state of the worker.

[0041] The force sensor 700, the display screen 600, the control module 400, and the signal sending unit 500 described above can be purchased from the market according to actual conditions.
