[0023] The two rotating shafts 21 can be driven to rotate by the manual operating member 26, which makes the two winding wheels 22 rotate synchronously and can reel in or release the wire 23, thus avoiding the problem of the wire 23 being too long and getting tangled and dirty when idle; at the same time, the wire pressing member 27 can press the wire 23 and the winding wheel 22 tightly, thus avoiding the problem of the wire 23 being entangled due to lateral translation on the winding wheel 22.

[0024] Reference Figure 3The manual operating member 26 includes two worm gears 261, which are respectively fixedly connected to one end of the two rotating shafts 21. The bottom of the multimeter body 1 is rotatably connected to a worm 262 that penetrates the bottom wall of the multimeter body 1. Both worm gears 261 are meshed with the worm 262, and a rotating cap 263 is fixedly connected to the bottom end of the worm gear 261.

The spring 2714 can apply elastic force to the slider 2713, which makes the sleeve rod 2712 subject to an outward thrust, and also makes the sleeve rod 2712 apply thrust to the mounting seat 272, which makes the wire pressing wheel 273 apply pressure to the wire 23, and also makes the wire 23 be pressed to prevent the wire 23 from lateral translation.
