Abstract

The utility model discloses a pipe cutting tong. The pipe cutting tong comprises a tong frame, wherein two tong heads are in pin joint with the tong frame, and a tong arm is arranged on the rear portion of each tong head. Each tong head is of an arc shape, and each tong head is in pin joint with at least two round cutting blades. After being optimized, each tong arm comprises an additional handle. Or a connecting rod is connected with the rear end of each tong arm in a hinged mode, and the other end of each connecting rod is connected with a tensioning frame in a hinged mode. The tensioning frame is connected with a retracted threaded rod in a threaded mode, and the retracted threaded rod is connected with the tong frame. Simultaneously, the retracted threaded rod is connected with a motive power device. The pipe cutting tong has the advantage of being labor-saving when in use.

Description

The pipe cutting pincers

Technical field

The present invention relates to the cutting tool technical field, especially relate to a kind of pipe cutting pincers.

Background technology

Usually, be used for assisting the cutting clamp that cuts the tubing such as plastic tube to comprise tong holder, the tong holder left and right sides is articulated with binding clip, and binding clip is provided with cutting blade, and simultaneously, the rear portion of binding clip is provided with clamp handle.Like this, the cutting blade that tubing is positioned over binding clip is inboard, inwardly tightens up clamp handle.At this moment, binding clip inwardly shrinks, thus cutting blade chucking tubing.Then, the circumgyration incision pincers make cutting blade form annular groove in tube surfaces.Afterwards, break the broken pipe material off with the fingers and thumb or tubing separates voluntarily along annular groove.Although such cutting clamp is easy to use, during the circumgyration incision pincers, the frictional force between binding clip and the tubing is larger, comparatively effort.Therefore be necessary to be improved.

Summary of the invention

For the deficiency that above-mentioned prior art exists, the purpose of this invention is to provide a kind of pipe cutting pincers, it has when use labour-saving characteristics comparatively.

To achieve these goals, the technical solution adopted in the present invention is: the pipe cutting pincers, comprise tong holder, and be articulated with 2 binding clips on the tong holder, the binding clip rear portion is provided with clamp handle, and described binding clip is curved, and all is articulated with at least 2 circular cutting blades on each binding clip.

Cutting blade on described each binding clip is 2.

Cutting blade on described each binding clip is 3.

Cutting blade on described each binding clip is 4.

The described in twos symmetry of 2 cutting blades on the binding clip that lays respectively at.

Described clamp handle includes auxiliary handle.

Described clamp handle rear end is hinged with connecting rod, and the other end of connecting rod is hinged on the tension frame, be bolted with expansion screw on this tension frame, and expansion screw is connected with tong holder, and simultaneously, expansion screw is connected with power set.

Described power set are that the expansion screw rear end is fixed with swing handle.

Described power set are that the expansion screw rear end is connected with electric device.

After adopting said structure, the present invention is compared with existing technology the advantage that has and is: comparatively laborsaving during use.The binding clip part of cutting clamp of the present invention is inwardly curved, thus the preferably combination of binding clip and tubing.Cutting blade is circular, and is a plurality of, thereby cutting blade is rotation status tubing is cut, and has reduced the frictional force between cutting blade and the tubing.The power set that the clamp handle rear portion is provided with auxiliary handle or connects by connecting rod realize that binding clip is to the compression of tubing.Above measure has all reduced dynamics required when this cutting clamp operates, and makes operation comparatively laborsaving.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 is the front view (broken section) of embodiments of the invention 1;

Fig. 2 is the front view (broken section) of embodiments of the invention 2;

Fig. 3 is the front view (broken section) of embodiments of the invention 3.

The specific embodiment

The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.

Embodiment 1, as shown in Figure 1: the pipe cutting pincers, comprise tong holder 12, be articulated with 2 binding clips 11 on the tong holder 12, binding clip 11 rear portions are provided with clamp handle 13.Like this, clamp handle 13 and binding clip 11 forms levers, and fulcrum is on tong holder 12, thereby clamp handle 13 compresses, and can realize the compression of binding clip 11.Wherein, binding clip 11 is curved, and all is articulated with at least 2 circular cutting blades 111 on each binding clip 11.In the present embodiment, the cutting blade 111 on each binding clip 11 is 2, and lays respectively in twos symmetry of 2 cutting blades 111 on the binding clip 11.Certainly, symmetry axis is the vertical center line of tong holder 12.Like this, binding clip 11 can be held the tubing of required cutting tightly, and cutting blade 111 is peripheral around tubing comparatively uniformly, and then after binding clip 11 compressions and the rotation, cutting blade 111 is rotation status tubing is cut, and is comparatively laborsaving.

Optimize, clamp handle 13 includes auxiliary handle 131.Like this, be equivalent to prolong the length of clamp handle 13, and then more the compression of binding clip 11 is realized in the labour-saving.

Embodiment 2, as shown in Figure 2: be with the difference of embodiment 1:

1), the cutting blade 111 on each binding clip 11 is 3.Certainly, laying respectively at 2 cutting blades 111 on the binding clip 11 also can be symmetrical in twos.

2), clamp handle 13 rear ends no longer arrange auxiliary handle 131.Substitute, clamp handle 13 rear ends are hinged with connecting rod 22, and certainly, the rear end of 2 clamp handles 13 all is hinged with 1 connecting rod 22.The other end of these 2 connecting rods 22 is hinged at respectively on the tension frame 21.Simultaneously, be bolted with expansion screw 23 on this tension frame 21, and expansion screw 23 is connected connection with tong holder.Obviously, expansion screw 23 is connected with tong holder for expansion screw 23 rotatable connections.Such as, the rear end that the front end of expansion screw 23 is connected with tong holder connects by the dovetail structure.At this moment, expansion screw 23 is connected with power set.Like this, under the effect of power set, expansion screw 23 rotations, the variable in distance between tension frame 21 and the tong holder 12, connecting rod 22 pulls back or promotes forward the rear end of clamp handle 13, thus binding clip 11 inwardly compresses or outwards opens.The mode that above realization binding clip 11 compresses or opens, owing to adopting screw drive, then the use of this cutting clamp is more laborsaving.

Optimize, power set are that expansion screw 23 rear ends are fixed with swing handle 30.That is, artificial turn swing handle 30 can drive the rotation of expansion screw 23.

Embodiment 3, as shown in Figure 3: be with the difference of embodiment 2:

1), the cutting blade 111 on each binding clip 11 is 4.Certainly, laying respectively at 2 cutting blades 111 on the binding clip 11 also can be symmetrical in twos.

2), power set are that expansion screw 23 rear ends are connected with electric device 40.Like this, more automation of the operation of turn expansion screw 23, the operator is more laborsaving.
