Description

The control cable crust divests safe cutter

Technical field

The utility model relates to a kind of cable sheath and divests instrument, and particularly a kind of control cable crust divests safe cutter.

Background technology

Needs along with the development of the fast and stable of electric power system in recent years; In the newly-increased or transformation process of secondaries such as transforming plant protecting; The control cable quantity that needs is increasing, and the workload of before the electric power secondary installing personnel secondary connection secondary control cable head that lays being made also strengthens thereupon.But the traditional cable manufacture craft especially divesting technology of cable sheath does not have big improvement very for many years; The instruments such as paper knife, electrician's knife that adopt more, the speed that divests of crust is slow, and is high to operator's technological requirement; Because the control to dynamics is not easy to grasp; The bad control of the depth degree of peeling often causes cutter to fracture or deviates from, and can accidentally injure the staff in the time of serious.

The utility model content

The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of safe in utilization, and convenient and simple, the control cable crust that efficient is high divests safe cutter.

A kind of control cable crust divests safe cutter; Include handle of a knife and cutter head, its structural feature is: described cutter head is the cutter head of inner edge formula, and the bottom near cable on the cutter head is an arc; On handle of a knife, also be provided with a stopping means; It comprises the threaded connector of an arcuate member and setting and arcuate member one end, and described arcuate member cover is through on the handle of a knife, and locks on the handle of a knife through threaded connector.

Cutter head is the cutter head of inner edge formula; The camber design is adopted in the bottom of cutter head; Its piercing portion promptly broke away from control cable mail or shielding copper mesh surface after assurance cutter head part oblique cutting was gone into the control cable crust; Can not accidentally injure the mail or the shielding copper mesh of control cable, can be owing to cutter head and control cable mail too much contact the wearing and tearing that cause the cutter head part yet.Stopping means is made up of a camber spare and the threaded connector of a spacing usefulness; Its effect is after cutter head part oblique cutting is gone into the control cable crust, through screwing up threaded connector arcuate member and handle of a knife to be clamped control cable; Make cutter in the cable sheath strip all the time along same orbiting motion; Can be owing to the inequality of exerting oneself causes fractureing of cutter or deviates from the accidental injury staff.

Described threaded connector is a screw rod.

Described arcuate member or be metalwork, or be working of plastics.

The thickness of knife edge of described inner edge formula cutter head is suitable with the control cable skin thickness.

Described inner edge formula cutter head is for colluding the shape cutter head, and the blade that colludes the shape cutter head is arranged on the inner edge that colludes the shape cutter head.

In sum, the utility model is compared the following advantage of prior art:

The control cable crust of the utility model divests safe cutter and has that practicality is good, efficient is high, safe, and input cost is low, very easily promotes, and application prospect is advantage widely.

Embodiment

Below in conjunction with embodiment the utility model is described in more detail.

Embodiment 1

A kind of control cable crust shown in Fig. 1-3 divests safe cutter; Include handle of a knife 4 and cutter head 1, described cutter head is the cutter head of inner edge formula, and the bottom near cable on the cutter head is an arc; On handle of a knife, also be provided with a stopping means; It comprises the threaded connector 2 of an arcuate member 3 and setting and arcuate member one end, and described arcuate member cover is through on the handle of a knife, and locks on the handle of a knife through threaded connector.Described threaded connector is a screw rod.Described arcuate member or be metalwork.The thickness of knife edge of described inner edge formula cutter head is suitable with control cable 5 skin thickness.

Operating personnel's left hand is held the upper end of cable, and the right hand is gone into the control cable crust with tool insert part oblique cutting, with stopping means control cable is clamped then, and tensioning threaded rods cuts to desired location with right hand pulling handle until edge of a knife operation again and gets final product.The edge of a knife streaks the position, and cable skin promptly comes off out.　

It is identical with prior art that present embodiment is not stated part.
