[0021] This embodiment provides a digital multimeter that is convenient for storing wires, such as Figure 1-5 As shown, a digital multimeter for storing wires conveniently comprises: a device body 1 and a test lead body 2 arranged on one side of the device body 1; a storage box 3, wherein the storage box 3 is mounted on the top of the device body 1; a partition 4, wherein the partition 4 is fixedly installed in the storage box 3; a rotating rod 5, wherein the rotating rod 5 is rotatably installed in the storage box 3, and a fixing block 6 is mounted on the rotating rod 5; and a driving mechanism, wherein the driving mechanism is arranged on the storage box 3 and the rotating rod 5 and is used for driving the rotating rod 5 to rotate.

[0022] In this embodiment, when it is necessary to store the test lead body 2 or the wire, first open the box door to connect the wire through the connecting port and the notch on the partition 4, then place one end of it in the bayonet on the fixed block, fix it by the block 11, and then operate the driving mechanism to drive the rotating rod 5 to rotate, so that the rotating rod 5 winds the material to store it. When the material is stored, the material outside the storage box 3 slides into the storage box 3 through the connecting port, so that it is stored, and the storage is relatively quick.

[0023] In this embodiment, a bayonet and a mounting groove 7 are provided on the top of the fixed block 6, a connecting rod 8 is fixedly installed in the mounting groove 7, a return spring 9 and a slider 10 are sleeved on the connecting rod 8, a stopper 11 is fixedly installed on the top of the slider 10, and the stopper 11 is in sliding contact with the bayonet.

[0024] In this embodiment, when fixing the material, first pull the block 11 so that the block 11 drives the slider 10 to slide along the connecting rod 8, so that the slider 10 compresses the return spring 9, and the block 11 slides away from the bayonet. Then, place the material in the bayonet, release the block 11, and limit one end of the material to facilitate subsequent winding and storage.

[0025] In this embodiment, the driving mechanism includes an annular plate 12, a twist rod 13 and a group of bevel gears 14, the annular plate 12 is fixedly mounted on the rotating rod 5, the twist rod 13 is rotatably installed on one side of the storage box 3, one end of the twist rod 13 extends into the storage box 3, a group of bevel gears 14 are fixedly mounted on the twist rod 13 and the rotating rod 5, and a group of bevel gears 14 are meshed with each other.

[0026] In this embodiment, when the material needs to be stored, the screw rod 13 is first rotated so that the screw rod 13 drives the bevel gear 14 to drive the rotating rod 5 to rotate. At the same time, the annular plate 12 blocks the material to ensure that it will not contact the bevel gear 14, thereby ensuring that it will not be damaged.

An L-shaped plate is fixedly installed on the top of the storage box 3, and a screw 22 is threadedly installed on the L-shaped plate, and the screw 22 is adapted to the sealing plate 21.

[0032] In this embodiment, after the material is stored, the sealing plate 21 is first rotated so that the sealing plate 21 covers the connection port, and then the screw 22 is connected to the fixed thread of the sealing plate 21 to fix the sealing plate 21, thereby ensuring that the material will not be discharged through the connection port.

[0033] In this embodiment, a box door is hinged on one side of the storage box 3, and a clamping block is rotatably mounted on one side of the storage box 3, and the clamping block is in rotational contact with the box door.

[0034] In this embodiment, the box door is limited by a block to ensure its stability, which is beneficial to the storage operation of materials.
