One end of bar is fixed with connecting rod 31, and the middle part of connecting rod and supporting rod are connected, and is respectively fixed with clamping plate at the both ends of connecting rod
32, movable half slot 33 is equipped on the acting surface of clamping plate, fixed half slot and movable half slot mating reaction clamp cable.?
One end of clamping plate is equipped with trunnion 36, and the first inclined-plane 34 is equipped on trunnion.It is equipped on articulated shaft between lever and supporting rod
Torsional spring, under the action of torsional spring, clamping plate is contacted with the bottom of bracket.
To realize the locking to supporting rod, as shown in figure 3, locking assembly is equipped in the bottom of bracket, as shown in figure 4, lock
Only assembly includes fixed block 4, sliding block 42, spring 43, pushing block 44 and backing pin 46, and fixed block is hollow square structure and fixed block
It is fixed on the bottom of bracket, sliding block 42 is slidably fitted in the inner cavity of fixed block 41, spring is equipped between sliding block and inner cavity
43, sliding block is contacted with the inner sidewall of inner cavity under the action of the spring.Pushing block sliding slot 45 is equipped on fixed block, it is fixed on sliding block
There is pushing block 44, pushing block is slidably mounted in pushing block sliding slot, and a part of pushing block stretches out fixed block, pushes pushing block compressible spring
So that sliding block slides.Backing pin 46 is fixedly installed on sliding block, when the inner sidewall of sliding block and inner cavity contacts, one end of backing pin is stretched
Fixed block out, and the second inclined-plane 47 is equipped in the backing pin one end for stretching out fixed block.Second inclined-plane and the first inclined-plane mating reaction, such as
Shown in Fig. 7, lever is grasped, then presses supporting rod with finger, may make that clamping plate is gradually mobile to the side far from bracket.
When the distance between bracket and clamping plate are sufficiently large, cable 6 to be cut can be placed in fixed half slot.Then clamping is unclamped
Bar, under the action of torsional spring, clamping plate move closer to bracket until trunnion on the first inclined-plane and backing pin on the second contact of incline plane,
Hereafter with the further release of supporting rod, trunnion presses backing pin to fixed block medial movement, until the first inclined-plane and second is tiltedly
Emaciated face is from rear, and trunnion is in the gap 7 between backing pin bracket, as shown in figure 8, cable 6 is located at movable half slot and fixed half
In the holding chamber that circular groove surrounds, backing pin is ejected to fixed block under the action of the spring, and trunnion is contacted with backing pin, in turn
Realize the locking to supporting rod.
As shown in fig. 6, sawing slot 21 and mounting groove 23 are equipped on bracket, and sawing slot and fixed half slot perforation, sawing
Slot and mounting groove are separated by baffle 22, and motor sliding slot 24 is equipped on baffle, is slidably fitted with first motor in motor sliding slot
51, it is equipped with saw blade 5 in first motor output end, saw blade is placed in sawing slot 21.The second motor 56 is fixed in mounting groove, such as

It is rotatably equipped with worm gear 54, a gear 53 setting coaxial with worm gear is slidably fitted with rack gear 52, one end of rack gear in mounting groove
It is fixed in first motor, rack and pinion engagement cooperation.When second motor works, worm gear, worm screw, gear and rack gear can be passed through
The translation for driving first motor drives the rotation of saw blade by first motor.First, second motor by electric wire in lever with
Button electrical connection on lever, the working condition of the first, second motor is controlled by button.First motor, the second motor, tooth
Item, gear, worm gear and worm screw constitute driving mechanism.
As shown in Figure 12 and Figure 13, to guarantee that good sawing effect, the structure of saw blade 5 have done special designing, saw blade includes
The centrally located saw heart 91 and positioned at outside saw along 92, the saw heart is circular metalwork, and the center for sawing the heart is equipped with and first is electric
The circular hole of machine output shaft fixed connection, the saw heart has certain thickness, and to guarantee enough intensity, the thickness design of the saw heart is 3-
6mm.Saw is sawed and is fixed together on the outside of the inside and the saw heart on edge along being cirque structure, and saws the thickness on edge to the periphery from center
Degree is gradually reduced.Several sawtooth 9 being uniformly arranged in the circumferential direction are fixed on the outer wall on saw edge, sawtooth is quadrilateral structure, saw
Gap 95 is formed between tooth, and small sawtooth can be set on the arris of sawtooth, to enhance sawing effect.As shown in figure 14, exist
It saws and is respectively equipped with several first reinforcing ribs 93 in the both ends of the surface on edge, several first reinforcing ribs on each end face are circumferentially uniformly set
It sets, and the first reinforcing rib is strip structure, the first reinforcing rib is arranged radially along saw edge.Every two first adjacent reinforcing ribs it
Between be equipped with the second arc-shaped reinforcing rib 94.By the setting of the first, second reinforcing rib, guarantee saw along enough structural strengths.
To realize the dimensional measurement to cable core, as shown in figure 11, it is equipped with circular measured hole on lever 1, is surveying
Transparent template 12 is fixed in metering-orifice, template is plastic part, several the first graduation marks 13 being uniformly arranged are equipped on template,
The second graduation mark 14 is equipped between every two first adjacent graduation marks, the second graduation mark is located in two first adjacent graduation marks
Between, the length of the second graduation mark is greater than the length of the first graduation mark, in order to read.The cable cut is put into measured hole,
The core size of cable is read according to the first, second graduation mark.
In use, cable is placed in fixed half slot and movable half slot and is realized by locking assembly to supporting rod
After locking, as shown in Fig. 2, the second motor of starting and first motor, saw blade rotates on one side at this time, on one side to the side where cable
It is close.At this point, saw blade is by cable cutting.Due to the effect of fixed half slot and movable half slot, during cutting cable,
Cable is gripped by circular holding chamber without deforming, and then can guarantee precision when measurement.When cutting small diameter
Cable when, as shown in Figure 10, liner plate 8 can be placed respectively in fixation, movable half slot, liner plate is the metal of semicircular arc
Inserted block 81 is arranged on liner plate outer wall, liner plate is mounted on bracket or clamping plate by the cooperation of inserted block and cone tank for plate.It will cut
Under cable be put into measured hole after, the size of cable core can be measured.
