DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] like Figure 1 As shown, a safe small transformer includes a transformer body 1, a knob 2 is installed on the transformer body 1, and output end wires 3 and input end wires 4 are respectively arranged at both ends of the transformer body 1. When using the small transformer at home, it is necessary to insert the input end wire 4 into the power socket, connect the output end wire 3 to the equipment to be powered, and then rotate the knob 2 to adjust the output voltage. An auxiliary mechanism 5 is arranged on the output end wire 3, and the auxiliary mechanism 5 can cause the output end wire 3 to be connected with other wires. When using this product, when it is necessary to connect the transformer body 1 with other electrical appliances, first insert the input end wire 4 of the transformer body 1 into the socket, and then connect the power line of the other electrical appliances with the output end wire 3 of the transformer body 1. During the wiring process, the auxiliary mechanism 5 is used to electrically connect the power line of the other electrical appliances with the output end wire 3 of the transformer body 1, thereby avoiding direct contact of the operator's hand with the output end wire 3 that may be energized, thereby improving the safety of the wiring process.
[0024] like Figure 2 , Figure 3As shown, the auxiliary mechanism 5 includes a frame 6 and a clamping assembly. The frame 6 is fixedly connected to the output end wire 3. The frame 6 can be made of insulating materials such as plastic. The clamping assembly is movably arranged in the frame 6 and can cause other wires to be close to the output end wire 3. During the wiring process, when the output end wire 3 needs to be fiddled with, the insulating frame 6 can be held by hand, and then the wires of other electrical appliances are inserted into the frame 6, and then the clamping assembly on the frame 6 is used to make the two wires close to each other to generate a wire connection. The clamping assembly includes a clamping block 7 slidably arranged in the frame 6 and a push rod 8 threadedly connected to the frame 6. The push rod 8 is threadedly connected to the frame 6. The rod 8 can push the clamping block 7 to move toward the direction close to the output end wire 3. During the clamping process, the operator rotates the push rod 8 threadedly connected to the frame 6. At this time, the push rod 8 begins to push the clamping block 7 to move toward the direction close to the output end wire 3, and the wires of other electrical appliances inserted between the output end wire 3 and the clamping block 7 will also be pushed. When pushed to a certain distance, the wires of other electrical appliances begin to contact the output end wire 3 of the transformer body 1. At this time, the push rod 8 continues to be rotated to push the clamping block 7, and the clamping block 7 continues to push the wire to make it close to the output end wire 3, thereby ensuring stable contact.
[0025] For example Figure 3 , Figure 4 As shown, a track 9 is provided on the frame 6, and protrusions 10 are fixedly provided at both ends of the clamping block 7. The protrusions 10 can extend into the track 9 and slide along the track 9. By providing the track 9 and providing the protrusions 10 that can extend into the track 9, a certain limiting effect is exerted on the clamping block 7, so that its movement direction always remains on the track 9.
[0026] Refer to Figure 2 As shown, a rotating member 11 is provided at one end of the push rod 8, and the rotating member 11 is composed of a disk 12 and a plurality of long rods 13 arranged in an array. The disk 12 is fixedly connected to the push rod 8, and the plurality of long rods 13 are fixedly connected to the disk 12. By providing the long rods 13, it is convenient for the operator to apply better force when rotating the push rod 8, and to twist the push rod 8 threadedly connected to the frame 6 more smoothly.
[0027] like Figure 1 As shown, the wire on the input end wire 4 is connected to a plug 14, and the plug 14 is wrapped with an insulating shell. When the input end wire 4 is inserted into the socket, the plug 14 can be directly used, making the insertion process more convenient. In addition, the insulating shell is provided on the plug 14, which also avoids the risk of electric shock when inserting the input end wire 4.
[0028] Finally, if Figure 5As shown, the output end wire 3 is wrapped with an insulating layer, and the insulating layer separates the output end wire 3 into a conductive portion 15 and an insulating portion 16. The conductive portion 15 is fixedly connected to the frame 6 and will never extend outside the frame 6. This design can ensure that when the frame 6 is held by hand, the hand will not touch the conductive portion 15 on the output end wire 3. Only the wires of other electrical appliances inserted into the frame 6 will contact the conductive portion 15 of the output end wire 3 under the action of the clamping assembly and generate an electrical connection, which further improves safety.
