The probe adjustment component comprises a movable terminal 31, and the movable terminal 31 is arranged on the right side of the bottom end of the fixed terminal 3, and a movable block 32 is fixedly connected to the top end of the movable terminal 31, and the movable terminal 31 is electrically connected to the movable block 32, and the movable block 32 is threadedly connected to the outside of the screw 33, and the screw 33 rotates The movable chamber 34 is connected to the inside of the movable chamber 34, and the movable chamber 34 is opened on the fixed terminal 3. The top of the movable block 32 is fitted with the conductive plate 35, and the movable block 32 is electrically connected to the conductive plate 35. The conductive plate 35 is electrically connected to the detection terminal 2 through a wire. A transmission assembly is arranged on the left side of the screw rod 33. The top of the detection terminal 2 is fixedly connected with an extension block 61, and the extension block 61 is inserted into the inside of the bottom of the device body 1. The extension block 61 is electrically connected to the device body 1 through a wire. The transmission assembly includes a first pulley 36, the first pulley 36 is fixedly connected to the left side of the screw rod 33, and the outer side of the first pulley 36 is sleeved with a transmission belt 37, and the other end of the transmission belt 37 is sleeved on the outer side of the second pulley 38. The second pulley 38 is fixedly connected to the outer side of the transmission shaft 39, and the transmission shaft 39 is rotatably connected to the inner wall of the transmission chamber 50. The transmission chamber 50 is opened inside the device body 1, and the transmission belt 37 is transmission-connected with the second pulley 38 and the first pulley 36. During operation, when the spacing between the fixed terminal 3 and the movable terminal 31 is to be adjusted, it is only necessary to rotate the knob 48 to drive the fixedly connected active shaft 47 to rotate synchronously, so that the active shaft 47 drives the connecting shaft 44 to rotate synchronously through the moving block 46 and the moving groove 45, and the connecting shaft 44 rotates to drive the fixedly connected sleeve shaft 40 to rotate synchronously. When the sleeve shaft 40 rotates, the cooperation of the first slide groove 42 and the first spring 43 drives the transmission shaft 39 to rotate synchronously. The rotation of the transmission shaft 39 drives the second pulley 38 fixedly connected to its outer side to rotate synchronously. The second pulley 38 drives the first pulley 36 to rotate synchronously through the transmission belt 37. The rotation of the first pulley 36 drives the screw rod 33 to rotate synchronously, so that the movable block 32 threadedly connected to the screw rod 33 moves inside the movable cavity 34, and drives the fixedly connected movable terminal 31 to move synchronously, so as to adjust the spacing between the fixed terminal 3 and the movable terminal 31, so that it can be adapted to insulators of different specifications.

[0022] Furthermore, the length adjustment component includes a sleeve shaft 40, which is inserted into the interior of the transmission shaft 39, and the upper and lower ends of the inner wall of the transmission shaft 39 are fixedly connected with a first slider 41, and the first slider 41 is slidably connected to the interior of the first slide groove 42. The first slide groove 42 is opened on the upper and lower ends of the sleeve shaft 40, and a first spring 43 is also provided inside the transmission shaft 39. The sleeve shaft 40 is fixedly connected to the connecting shaft 44, and a moving groove 45 is opened on the outer side of the connecting shaft 44, and the connecting shaft 44 is inserted into the interior of the driving shaft 47. The interior of the moving groove 45 is slidably connected with a moving block 46, and the moving block 46 is fixedly connected to the inner wall of the driving shaft 47. The outer side of the driving shaft 47 is fixedly connected with a first gear 49, and the first gear 49 is meshed with the second gear 51. The second gear 51 is rotatably connected to the inner wall of the transmission cavity 50, and the second gear 51 is meshed with the transmission cavity A torsion spring 52 is arranged between the inner walls of 50, a rotation limiting assembly is arranged at the bottom end of the second gear 51, the second gear 51 is also meshed with a rack 53, the rack 53 is slidably connected to the inside of the transmission chamber 50, and the top of the rack 53 is fixedly connected to the bottom end of the device body 1, the end of the first spring 43 close to the sleeve shaft 40 is fixedly connected to the sleeve shaft 40, and the end of the first spring 43 away from the sleeve shaft 40 is fixedly connected to the inside of the transmission shaft 39, the side of the torsion spring 52 close to the second gear 51 is fixedly connected to the second gear 51, and the side of the torsion spring 52 away from the second gear 51 is fixedly connected to the inner wall of the transmission chamber 50, the end of the driving shaft 47 away from the connecting shaft 44 passes through the device body 1 and extends to the outside of the device body 1, and the end of the driving shaft 47 away from the connecting shaft 44 is fixedly connected with a knob 48, and the outer side of the knob 48 is provided with anti-slip grooves.

[0023] When the length of the device as a whole is to be adjusted, the knob 48 is first pulled in the direction away from the detection end 2. Under the action of the pulling force, the knob 48 drives the moving block 46 to slide synchronously inside the moving groove 45 through the active shaft 47, so that the moving block 46 enters the annular groove on the right side of the moving groove 45. As the active shaft 47 moves, the first gear 49 fixedly connected to the outside of the active shaft 47 also moves synchronously to a position meshing with the second gear 51. At this time, the knob 48 is turned to drive the first gear 49 to rotate through the active shaft 47. Because the moving block 46 falls in the annular groove inside the moving groove 45, the moving block 46 will not drive the connecting shaft 44 to rotate synchronously when it rotates. The first gear 49 rotates step by step, and the meshing second gear 51 rotates synchronously. The rotation direction of the second gear 51 is limited by the rotation limiting component, so that the second gear 51 can only drive the rack 53 to move upward. When the second gear 51 rotates, it drives the meshing rack 53 to move upward, and the jacking device body 1 also moves synchronously, so that the extension block 61 also moves synchronously inside the device body 1. The extension block 61 plays the effect of maintaining the data transmission and circuit connection between the device body 1 and the detection terminal 2. When the second gear 51 rotates, it drives the fixedly connected torsion spring 52 to twist synchronously, so that the torsion spring 52 produces elastic deformation.

[0024] Further, the rotation limiting assembly includes a card block 54, a second slider 55 is fixedly connected to the right side of the card block 54, the second slider 55 is slidably connected to the inside of the second slide groove 56, the second slide groove 56 is opened on the left side of the telescopic block 58, and a second spring 57 is also provided inside the second slide groove 56, the right side of the telescopic block 58 is inserted into the inside of the telescopic seat 60, the telescopic seat 60 is fixedly connected to the inner wall of the transmission chamber 50, and a third spring 59 is also provided inside the telescopic seat 60, the top end of the second spring 57 is fixedly connected to the second slider 55, and the bottom end of the second spring 57 is fixedly connected to the inner wall of the second slide groove 56, the side of the third spring 59 close to the telescopic block 58 is fixedly connected to the telescopic block 58, and the side of the third spring 59 away from the telescopic block 58 is fixedly connected to the inner wall of the telescopic seat 60; During operation, when the second gear 51 rotates forward, the second gear 51 squeezes one side of the arc surface of the block 54, so that the block 54 moves downward under the action of the squeezing force and the arc surface opened thereon, and drives the fixedly connected second slider 55 to slide synchronously inside the second slide groove 56, and squeezes the second spring 57, so that the second spring 57 produces elastic deformation. After the second gear 51 stops rotating, the squeezing force of the second gear 51 on the block 54 disappears. At this time, the second slider 55 pushes the block 54 to return to the original position under the action of the restoring force of the second spring 57. The second gear 51 is engaged with the original position. When the second gear 51 is to rotate in the opposite direction, the front side of the block 54 is engaged with the second gear 51 so that the second gear 51 cannot rotate smoothly, thereby limiting the rotation direction of the second gear 51 and fixing the overall length of the device. When the device is to restore its initial length, it is only necessary to continue to pull the knob 48 in the direction away from the detection end 2. At this time, the knob 48 pulls the connecting shaft 44 to move synchronously through the active shaft 47 and the moving block 46. The connecting shaft 44 pulls the sleeve shaft 40 to move synchronously, causing the sleeve shaft 40 to move. The first spring 43 is pulled to produce elastic deformation. In this process, the first gear 49 gradually abuts against the block 54 as the driving shaft 47 continuously moves to the right, and squeezes the block 54, so that the block 54 drives the telescopic block 58 to move toward the inside of the telescopic seat 60, and the restriction on the rotation direction of the second gear 51 is released. At this time, the second gear 51 automatically reverses under the action of the restoring force of the torsion spring 52, and the reverse rotation of the second gear 51 drives the first gear 49 to reverse synchronously. The rotation of the first gear 49 drives the driving shaft 47 and the knob 48 to rotate synchronously. By controlling the knob 48 The shortened length of the device as a whole can be controlled. When the specified length is adjusted, the knob 48 is released. At this time, the sleeve shaft 40 is restored to its original position under the restoring force of the first spring 43 and reinserted into the interior of the transmission shaft 39. The first gear 49 is also driven to move slightly to the left through the connecting shaft 44, the moving groove 45, the moving block 46 and the active shaft 47, so that the first gear 49 releases the squeezing of the block 54. At this time, the block 54 and the telescopic block 58 are also restored to their original positions under the restoring force of the third spring 59, and continue to limit the rotation direction of the second gear 51.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
