[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This utility model discloses a safety protection device for engineering electrical debugging, such as Figure 1-8 As shown, the device includes a wearing box 1, a holding box 3, and a test pen 302 for engineering electrical use located inside the holding box 3. The probe of the test pen 302 contacts a live body, and the current forms a circuit through the probe, the neon tube, the human body, and the ground. The neon tube lights up when the starting voltage is reached. If the neon tube lights up, it indicates that there is electricity. If the neon tube does not light up, it indicates that there is no electricity.

[0026] The device is tested using a voltage tester 302 to determine whether it is energized, thus preventing staff from getting too close when they are unsure whether there is a leakage and thus protecting their safety.

[0027] By placing the test pen 302 inside the holding box 3, the holding box 3 can prevent the test pen 302 from being damaged by collision with external objects during the construction personnel's carrying process.

[0028] The grip box 3 can be easily disassembled by wearing the box 1, so that when the grip box 3 is damaged, it is easy to replace it with a new grip box 3.

[0029] An elastic wristband 2 is fixedly installed on the bottom surface of the wearing box 1. The elastic wristband 2 is made of nylon and spandex. The construction personnel can carry the wearing box 1 with them by wearing the elastic wristband 2 on their arm.

[0030] The wearing case 1 has two racks 1021 inside, and two slide bars 101 that pass through the racks 1021 are provided on the racks 1021. The two slide bars 101 are fixedly installed inside the wearing case 1, and the two racks 1021 can move along the slide bars 101.

[0031] The inside of the wearing box 1 is rotatably connected to a gear 1022, which is located between two racks 1021. The gear 1022 meshes with the two racks 1021. When one of the racks 1021 moves, it will drive the gear 1022 to rotate. The rotating gear 1022 will then push the other rack 1021 to move in the opposite direction.

[0032] A connecting plate 102 is fixedly installed on one side of each of the two racks 1021. When the two racks 1021 move, they will drive the two connecting plates 102 to move as well. A clamping plate 106 is fixedly installed on one side of each connecting plate 102 extending to the outside of the wearing case 1. The holding case 3 is located between the two clamping plates 106. When the two clamping plates 106 come close to each other, the holding case 3 can be clamped and fixed, which facilitates the quick disassembly of the holding case 3 and the replacement of the damaged holding case 3.

[0033] The inner walls of the wearing box 1 are fixedly installed with two first springs 103, and the two first springs 103 are fixedly connected to the two connecting plates 102 respectively. When the two connecting plates 102 move away from each other, they will compress the two first springs 103.

[0034] A connecting rod 104 is fixedly installed on one side of the two connecting plates 102. Part of the connecting rod 104 is located inside the wearing case 1, and the other part is located outside the wearing case 1. A pull ring 105 is fixedly installed on the end of the connecting rod 104 located outside the wearing case 1.

[0035] Pulling the pull ring 105 causes the connecting rod 104 to move one of the connecting plates 102 toward the corresponding first spring 103, which in turn moves one of the racks 1021. In conjunction with the rotation of the gear 1022, the other rack 1021 moves the other connecting plate 102 in the opposite direction, causing the two clamping plates 106 to move away from each other and not clamp the gripping box 3, thus allowing the gripping box 3 to be removed.

[0036] A second spring 303 is fixedly installed on one side of the inside of the grip box 3, and a movable block 301 is fixedly installed on one end of the second spring 303 at the opening of the grip box 3. The test pen 302 contacts the side of the movable block 301 away from the second spring 303. When the movable block 301 moves toward the side of the second spring 303, it will squeeze the second spring 303.

[0037] A movable hole 3021 is provided in the middle of the outer top surface of the grip box 3. A hook 3022 is fixedly installed on the top surface of the movable block 301, and the hook 3022 passes through the movable hole 3021 and extends to the outside of the grip box 3. A rope ring 3023 is fixedly installed on one side of the outer top surface of the grip box 3. The rope ring 3023 is woven from existing silk threads.

[0038] Pull the hook 3022, causing the hook 3022 to move the movable block 301 toward the side of the second spring 303, thereby squeezing the second spring 303. Then, put the rope loop 3023 on the hook 3022 to prevent the squeezed second spring 303 from pushing the movable block 301 to reset. Then, place the test pen 302 in the holding box 3. When the test pen 302 needs to be used, remove the rope loop 3023 from the hook 3022. The squeezed second spring 303 will then push the movable block 301 to reset, thereby pushing the test pen 302 toward the opening of the holding box 3, so as to push the test pen 302 to the outside of the holding box 3.

[0039] A rubber plug 3032 is fixedly installed on one side of the opening of the grip box 3. The rubber plug 3032 is made of rubber and has a certain deformation capability. A fixing plate 3031 is fixedly installed on one side of the rubber plug 3032. By inserting the rubber plug 3032 into the opening of the grip box 3, the opening of the grip box 3 can be sealed to prevent the test pen 302 from falling out when carried by the person.

[0040] The working principle of this utility model is as follows: the construction worker pulls the hook 3022, causing the hook 3022 to move the movable block 301 towards one side of the second spring 303, so as to squeeze the second spring 303. Then, the rope loop 3023 is put on the hook 3022, which can prevent the squeezed second spring 303 from pushing the movable block 301 to reset. Then, the test pen 302 is placed in the holding box 3, and the rubber plug 3032 is inserted into the opening of the holding box 3 to seal the opening of the holding box 3.

[0041] The construction worker pulls the pull ring 105, causing the connecting rod 104 to move one of the connecting plates 102 towards the corresponding first spring 103. This moves one of the racks 1021, and in conjunction with the rotation of the gear 1022, causes the other rack 1021 to move the other connecting plate 102 in the opposite direction, thus moving the two clamping plates 106 away from each other. Then, the holding box 3 is placed between the two clamping plates 106, and the pull ring 105 is released. The two compressed first springs 103 then push the two connecting plates... The connecting plates 102 are brought close together, so that the two clamping plates 106 clamp and fix the holding box 3. The construction personnel can carry the wearing box 1 with them by wearing the elastic wristband 2 on their arm. When the electrical debugging of the project is carried out, the construction personnel pull out the rubber plug 3032 and remove the rope loop 3023 from the hook 3022. The squeezed second spring 303 will push the movable block 301 to reset, and then push the test pen 302 towards the opening of the holding box 3 to push the test pen 302 to the outside of the holding box 3 so as to take out the test pen 302.
