[0002] A multimeter, also known as a multimeter, multimeter, or multimeter, is a multi-purpose electronic measuring instrument. It is divided into two types: pointer multimeter and digital multimeter. A multimeter consists of a magnetoelectric current, a measuring circuit, and a selection switch. Its principle is to measure a variety of electrical parameters by changing the selection switch. The basis of its circuit calculation is Ohm's law of a closed circuit. A multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio level, etc. It is mainly used in the measurement fields of physics, electricity, and electronics.

[0003] However, most of the existing multimeters do not have a structure for storing the test leads after use. Most of them are directly folded and placed together with the multimeter. In this way, the multimeter is separated from the test leads, which may easily cause the test leads to be lost, affecting the normal use of the multimeter. In addition, the folded wires are prone to entanglement with each other. The entangled wires are not only inconvenient to use, but also excessive insertion may cause damage to the wires, reducing the applicability of the multimeter when used. At the same time, the existing multimeters also lack a structure to protect the test leads. The test leads and wires are exposed to the outside and are easily damaged, affecting the normal use of the multimeter. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6As shown, a multimeter includes a multimeter body 1, which can detect voltage in electrical engineering. Both sides of the surface of the multimeter body 1 are fixedly connected with a connection shell 2, one side of the connection shell 2 is provided with a storage groove 3, and the storage groove 3 is designed as an S-shaped structure. One side of the connection shell 2 is provided with a protection hole 4, and the inner cavity of the protection hole 4 is slidably connected with a connector 6. When the connector 6 is not in use, it can be inserted into the inside of the protection hole 4 to protect the connector 6 and avoid the connector 6 being directly exposed to the air and damaged. One end of the connector 6 is electrically connected to a wire 7, and the wire 7 The surface of is slidably connected to the inner wall of the storage groove 3, under which the storage groove 3 can store the wire 7 so that it will not be tangled together, which not only improves the service life of the wire 7 but also is more convenient to use. The other end of the wire 7 is electrically connected to a test lead 8, and the surface of the test lead 8 is slidably connected to the inner wall of the storage groove 3. Under the action of the storage groove 3, the test lead 8 can also be protected. A flexible sleeve 5 is fixedly connected to one side of the inner cavity of the storage groove 3, and the flexible sleeve 5 is designed as a sponge. The flexible sleeve 5 is used in conjunction with the test lead 8. Under this action, one metal end of the test lead 8 can directly contact the flexible sleeve 5, so as to protect the test lead 8. The pen 8 is protected to prevent the pen 8 from being easily bent and broken. A positioning plate 9 is fixedly connected to the surface of the pen 8, and a clamping mechanism 10 is provided at the bottom of the connecting shell 2. The clamping mechanism 10 is used in conjunction with the positioning plate 9 to conveniently limit the pen 8 so that it will not be separated from the inner cavity of the storage slot 3 when not in use, effectively improving the protection effect of the pen 8. A connecting plate 11 is fixedly connected to the inner cavity of the storage slot 3. The number of connecting plates 11 is several and they are symmetrically distributed in groups of two. The connecting plate 11 is designed as an inclined structure and is made of plastic material. After the lower connecting plate 11 is tilted, it can return to its original position due to the effect of its own material. A positioning block 12 is fixedly connected to the surface of the connecting plate 11. The positioning block 12 is wedge-shaped, and the surface of the positioning block 12 is chamfered. Under this effect, when limiting the position of the wire 7, the wire 7 can be directly pressed into the storage groove 3. Under the effect of the shape of the positioning block 12 and the material of the connecting plate 11, the positioning block 12 can be deformed to allow the wire 7 to enter the storage groove 3. After the wire 7 enters, the positioning block 12 can return to its original position to block the wire 7, which effectively improves the storage effect of the multimeter for the wire 7.

[0024] The locking mechanism 10 includes a mounting shell 101, the surface of the mounting shell 101 is fixedly connected to the surface of the connecting shell 2, the inner cavity of the mounting shell 101 is fixedly connected to a compression spring 102, the other end of the compression spring 102 is fixedly connected to a moving block 103, the surface of the moving block 103 is slidably connected to the inner wall of the mounting shell 101, under this action, after the moving block 103 is moved, the compression spring 102 can push it back to its original position, the top of the moving block 103 is fixedly connected to a limiting frame 104, the surface of the limiting frame 104 is movably connected to the positioning plate 9, under this action, when the test lead 8 is stored, the limiting frame 104 can move the positioning plate 9 under the action of the compression spring 102 The guide rod 13 is fixedly connected to the inner cavity of the mounting shell 101, and the other end of the guide rod 13 penetrates to the other end of the moving block 103 and is slidably connected to the inner wall of the penetration point. The guide rod 13 is located inside the compression spring 102. Under this action, the guide rod 13 can limit the moving block 103, so that it can be more stable when moving, and can also guide the compression spring 102, so that it can be more stable during compression or rebound, to avoid the compression spring 102 being unstable and affecting the moving effect of the moving block 103.

[0025] It is worth noting that the technical features such as the multimeter body 1, connector 6, wire 7 and test lead 8 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0026] Working principle: First, when not in use, insert the connector 6 into the protection hole 4 to protect the connector 6, then press the wire 7 into the storage slot 3 according to the shape of the storage slot 3, and with the cooperation of the connecting plate 11 and the positioning block 12, the wire 7 can be limited so that it will not be easily moved out from the storage slot 3, then pull the limit frame 104 to enable it to move, then insert the test lead 8 into the flexible sleeve 5 to protect the test lead 8, and then release the limit frame 104. Under the action of the compression spring 102, the limit frame 104 will be driven by the moving block 103 to squeeze and limit the positioning plate 9, so that it will not move easily, thereby limiting the test lead 8 so that it will not easily detach from the inside of the storage slot 3. When the connector 6, wire 7 and test lead 8 need to be used, they can be directly taken out.
