At the present stage, the wire clamp is mostly fixed by adopting a fixing device, and then the wire clamp is cut by moving back and forth along the direction of the wire by using an electric saw. The Chinese patent with the application number of 201620581324.3 discloses an electric forcible entry tool for a crimping type wire clamp, which comprises a base, a clamping mechanism arranged on one side of the base, a lifting mechanism arranged on the other side of the base and a cutting mechanism connected above the lifting mechanism; the base comprises a bottom plate, a clamping mounting plate, a lifting mounting plate and a bevel gear mounting plate; the clamping mechanism comprises a sliding rod, a fixed clamping block, a sliding clamping block, a screw rod and a clamping hand wheel, wherein one end of the screw rod is connected with the clamping hand wheel, and the other end of the screw rod is in threaded connection with the sliding clamping block and is used for driving the sliding clamping block to move horizontally; the lifting mechanism comprises a driving bevel gear, a driven bevel gear, a lifting platform and a lifting hand wheel; the cutting mechanism comprises a cutting disc, a motor and a front-back moving platform. The bottom of the front-back moving slide block is provided with a roller which is pressed on the bottom wall of the horizontal sliding chute. By adopting the structure, the cutting mechanism can swing left and right in actual operation to ensure that the cutting disc can not cut the wire clamp along a straight line, the cutting mechanism can be lifted upwards and can not be attached to the lifting platform, so that the cutting depth is insufficient and the wire clamp can not be completely cut, the screw rod of the clamping mechanism can only drive one clamping block to be close to the other clamping block, the central line position of the wire clamp can also be changed as long as the diameter of the wire clamp is changed, and the cutting disc can not cut the central line of the wire clamp along the line.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that improve prior art, design one kind with the fixed back of fastener of different diameters, the broken dismouting of fastener that can both the stable cutting of clamp central line along the line is put.

In order to solve the problem, the utility model adopts the following technical scheme:

the wire clamp breaking and dismounting device comprises a base plate, a wire clamp clamping mechanism fixed on the base plate, and a lifting platform arranged above the side of the wire clamp clamping mechanism, wherein a sliding groove is formed in the lifting platform. Two inside walls of spout are provided with the guide rail along the groove to, accompany the several between the guide rail and follow the rolling pulley of guide rail, are provided with the slide on the spout, and the lower extreme of slide is fixed with the pulley post downwards, and open at the pulley center has the through-hole, and the rotatable wearing of pulley is on the pulley post.

As a further improvement of the above technical solution:

the cross section of the guide rail is in a semicircular shape protruding out of the side wall of the sliding groove, and the pulley is provided with an annular groove for matching and embedding the guide rail. With the structure, the sliding plate can move along the cutting direction of the wire clamp more stably.

The sliding plate is provided with a fixing hole. The electric saw can be fixed on the sliding plate by screws, so that the electric saw can move linearly along the guide rail direction.

The wire clamp clamping mechanism comprises a pair of clamping blocks, a guide rod and a driving rod, wherein screw holes penetrating through the driving rod are formed in the clamping blocks, the driving rod is respectively in positive thread connection and negative thread connection with the screw holes of the two clamping blocks, a driving knob is arranged at one end of the driving rod, and a V-shaped groove with opposite openings is formed in the clamping blocks. Therefore, the two clamping blocks can be simultaneously close to the middle, so that the wire clamp is clamped.

A bearing is arranged between the pulley post and the pulley, the inner ring of the bearing is fixed on the pulley post, and the outer ring of the bearing is fixed on the through hole of the pulley. So that the slide can only move in the direction of the guide rail.

The utility model has the advantages that:

the structure that the pulley moves along the guide rail is adopted, and the electric saw for cutting the wire clamp can stably cut the wire clamp along a straight line. After the driving rod and the two clamping blocks are respectively connected by positive threads and negative threads, the central line of the wire clamp is always positioned under the saw blade after the wire clamps with different diameters are clamped, and the cutting position is ensured to be the central line of the wire clamp. Be provided with the bearing between pulley post and the pulley, make the electric saw slide more easily on the one hand, on the other hand makes the electric saw can not upwards mention, has guaranteed that the fastener depth of cut is unanimous.
