Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

A manual cable stripper capable of being accurately adjusted is shown in figure 1 and comprises an annular part 1, blades 2 and a screw rod 3, wherein the annular part 1 is open, connecting pieces are respectively arranged at two ends of the annular part, through holes are formed in the connecting pieces, the screw rod penetrates through the through holes, and the screw rod is used for adjusting the inner diameter of the annular part; specifically, one end of the screw rod 3 is provided with a first blocking portion 4, the other end of the screw rod is provided with a second blocking portion 6, the first blocking portion 4 is in threaded connection with the screw rod 3, the second blocking portion 6 is sleeved on the screw rod 3, and the first blocking portion 4 and the second blocking portion 6 are used for limiting the position of the ring-shaped member 1 on the screw rod 3. The position of the connecting piece on the ring-shaped piece 3 can be limited by arranging the first blocking part 4 and the second blocking part 6, and the ring-shaped piece 1 and the screw rod 3 can not be separated when the screw rod 3 is rotated again. Wherein the first blocking part 4 is also movable relative to the screw 3.

Further, as shown in fig. 2, a connecting member on the ring member 1 near the first blocking portion 4 is a first connecting member 7, a connecting member near the second blocking portion 6 is a second connecting member 8, a first through hole is formed in the first connecting member 4, a second through hole 12 is formed in the second connecting member 8, and the first through hole and the second through hole 12 are rotatably connected with the screw 3 respectively. Wherein, annular member 1 is the elastic component, through locating first connecting portion 7 and 8 covers of second connecting piece on the screw rod, encloses into closed annular with it, and when second stopper 6 was motionless, the accessible was rotatory first stopper 4 and is realized drawing close first connecting piece 7 and second connecting piece 8 and the restriction of position.

Further, as shown in fig. 1 to 3, a clamping member 9 is disposed on the first blocking portion 4, and the first connecting member 7 and the clamping member 9 are fixed by screws. By further fixing the first blocking part 4 and the first connecting piece 7, the positions of the first connecting piece 7 and the first blocking part 4 can be restricted from being relatively fixed, and by rotating the screw 3, the distance between the second connecting piece 8 and the first connecting piece 7 is changed.

Specifically, be equipped with scale 10 on the screw rod 3, the scale with screw rod 3 parallel arrangement, scale 10 with first barrier portion 4 fixed connection.

The manual cable stripper further comprises a crank 11, and the crank 11 is perpendicular to the axis of the second blocking portion 6. Because the screw rod 3 is thin, the staff can be more strenuous by manual rotatory screw rod 3 in the use, so utilize lever principle through set up crank 11 can increase moment on second stop part 6, make the regulation annular member 1 internal diameter process more laborsaving, convenient.

The working principle is as follows:

the cable that will treat the cutting penetrates in the loop forming element, rotate the second stop part, make the screw rod remove to first stop part direction, at the in-process of screw rod rotation translation, the second connecting portion remove to first connecting portion, the distance of screw rod translation is confirmed to the cable core number reference value that treats the cutting on the scale all the way, core number reference value on the scale increases from first connecting portion to second connecting portion in proper order, when rotatory to appropriate core number position, it is fixed to keep the cable, the whole barker device of horizontal rotation, can cut the cable oversheath, and can not damage the cable inner core.

The blade 2 is arranged inside the annular member 1, and the blade 2 can be arranged by various methods:

as shown in fig. 4, in this embodiment, the ring members include a first ring member 111 and a second ring member 112, the blades 2 are disposed in a sandwich layer between the first ring member 111 and the second ring member 112, and the first ring member 111 and the second ring member 112 are fixed by bolts 15. When the blade 2 is damaged or needs to be replaced after a certain period of time, the detachable bolt 15 is released to take out the blade 2 and replace it with a new blade 2.

Brief description of the principle of blade replacement: when the blade needs to be replaced, the bolt is loosened, the old blade is taken out, then the old blade is replaced by a new blade, and then the bolt is screwed.

Example 2

Preferably, on the basis of embodiment 1, as shown in fig. 5, the arrangement of the blades may be replaced by: the blades 2 are designed integrally with the ring 1.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
