The bottom of support is fixed on, sliding block 42 is slidably fitted with the inner chamber 41 of fixed block, spring is provided between sliding block and inner chamber
43, under the action of the spring sliding block contacted with the madial wall of inner chamber.Pushing block chute 45 is provided with fixed block, it is fixed on sliding block
There is pushing block 44, pushing block is slidably mounted in pushing block chute, and a part for pushing block stretches out fixed block, promotes pushing block compressible spring
So that sliding block slides.Backing pin 46 is installed with sliding block, when sliding block contacts with the madial wall of inner chamber, one end of backing pin is stretched
Go out fixed block, and the second inclined-plane 47 is provided with 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 be such that clamping plate gradually moves to the side away from support.
When the distance between support and clamping plate are sufficiently large, cable 6 to be cut can be placed in fixed half slot.Then clamping is unclamped
Bar, in the presence of torsion spring, clamping plate moves closer to support until the second contact of incline plane on the first inclined-plane and backing pin on journal stirrup,
Hereafter with the further release of supporting rod, journal stirrup presses backing pin to fixed block medial movement, until the first inclined-plane and second oblique
Emaciated face is from rear, in gap 7 of the journal stirrup between backing pin support, 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 journal stirrup contacts with backing pin, and then
Realize the locking to supporting rod.
As shown in fig. 6, being provided with sawing groove 21 and mounting groove 23 on support, sawing groove penetrates with fixed half slot, sawing
Groove and mounting groove are separated by baffle plate 22, and motor chute 24 is provided with baffle plate, the first motor is slidably fitted with motor chute
