Specific embodiment
The present invention as shown in Figure 1-3, include fixed cylinder 11, sealing plate 12, driving wheel 13, central axis 21, cylindrical central sleeve 22, around
Spool 23, conducting wire, coupling unit, reset assembly and changeover module offer rope hole on the outer wall of the fixed cylinder 11, described
Sealing plate 12 is fixedly connected on the side of fixed cylinder 11, and the driving wheel 13 is hinged on the other side of fixed cylinder 11, the fixed cylinder
Several brackets 111 obliquely are also fixedly connected on 11 outer wall, the bottom end of the bracket 111 is hinged with guide wheel 112, owns
The root edge of the guide wheel 112 is in same level with the root edge of driving wheel 13；
The central axis 21 is in ladder shaft-like and is divided into big axis and small axis, the big axis wear the driving wheel 13 and with driving
Wheel is hinged, and the cylindrical central sleeve 22 is set on the small axis and wears the sealing plate 12, the end face of the small axis far from big axis
On be fixedly connected with fixed plate 211 so that the cylindrical central sleeve 22 it is rotatable be set between big axis and fixed plate 211, it is described
Fixed plate 211 is fixedly linked with sealing plate 12, and the reel 23 is slideably socketed on the cylindrical central sleeve 22 and and center
22 synchronous rotary of sleeve；In this way, i.e. so that fixed cylinder, fixed plate, central axis three are fixedly linked, and cylindrical central sleeve, driving wheel
It can then make rotating motion relative to central axis, wherein reel keeps synchronous rotary with the cylindrical central sleeve moment again；
One end of the conducting wire is fixedly connected on rope drum 23, and several circles are arranged on rope drum 23, the conducting wire
The other end is extend out to except fixed cylinder 11 from rope hole；
The reset assembly includes plane scroll spring 41, and the plane scroll spring 41 is located at reel 23 far from driving wheel 13
Side and be set in outside cylindrical central sleeve 22, one end of the plane scroll spring 41 is fixedly connected on the inner wall of fixed cylinder 11
The upper and other end is fixedly connected on cylindrical central sleeve 22；
The coupling unit includes drag ring 31 and pressure spring 32, and the drag ring 31 is fixedly connected on reel 23 towards driving wheel
On 13 end face, the pressure spring 32 is against between driving wheel 13 and reel 23；
The changeover module includes that hinged seat 51, screw rod 52, nut 53, connecting rod 54 and switching ring 55, the hinged seat 51 are fixed
It is connected to the top of the outer wall of fixed cylinder 11, the screw rod 52 is hinged in hinged seat 51, and the nut 53 is socketed in screw rod 52
Above and with screw rod 52 it is threadedly coupled；Cylindrical central sleeve 22 described in 55 empty set of switching ring and reel 23 is against backwards to driving wheel
On 13 end face；The strip switching hole for being parallel to screw rod setting is also provided in the fixed cylinder 11, the connecting rod 54 is worn
The switching hole and be fixedly connected on nut 53 and switching ring 55 between.In this way, rotation screw rod may make nut and switching
Ring translation, so that reel is pushed, so that drag ring is close to or far from driving wheel.
Specifically, first, operator pushes directly on fixation when drag ring is close and is finally bonded on the drive wheel
Cylinder may make driving wheel to rotate under the friction effects on ground, and drive rope drum, cylindrical central sleeve rotation, thus in movement
During gradually release conducting wire；In the process, it due to driving wheel, rope drum, cylindrical central sleeve three's synchronous rotary, puts down
Restoring force effect that face scroll spring generates on the drive wheel, rather than on conducting wire, thus effective protection conducting wire, avoid its because
Excessively tense and caused by damage.
Second, the restoring force of plane scroll spring will be straight when drag ring is separate and is finally kept completely separate with driving wheel
It connects and acts on rope drum, can gradually pack up conducting wire after measurement.
In conclusion being switched fast between take-state, unwrapping wire state can be realized by turn screw rod in this case, put
When line, operator pushes fixed cylinder, and when take-up is then packed up by plane scroll spring automatically, to efficiently solve existing
Because the bring working efficiency of artificial retractable line is low, easily causes the problems such as conducting wire tangled up and knotted in technology, there is knot on the whole
Structure is exquisite, easy to operate, stability is good, work efficiency is high and good integrity, the advantages that being easy to carry about with one or storing, can after use
Working efficiency when being obviously improved retractable line, to substantially shorten the time of measuring of ground resistance.
