One end of the handle is connected with a connecting pipe; the front end part of the connecting pipe is provided with a screw thread section; the side face is provided with a longitudinal groove; the upper end part of the wire pressing head is provided with a column and the middle part of the wire pressing head is provided with a rectangular plate; the bottom part of the wire pressing head is provided with an inverse T-shaped platform; the upper end part of the wire pressing head is positioned in the connecting pipe along the longitudinal groove; the wire pressing head is connected with the connecting pipe for fixation by a locking screw. In the utility model, the wire pressing head is connected in a detachable and installing way; when broken, the utility model can be replaced; the utility model has the advantages of reasonable integrated design, material saving for manufacture in set, low cost, a handle for use by matching and portability.

Description

Combined wire pressing board

The utility model belongs to a kind of manual line ball instrument that is used for electric machine winding, is a kind of composite type tension disc specifically.

Present widely used tension disc majority is to make of stainless steel or brass, and it is made up of line ball head and handle two parts, and line ball head and handle are an overall structure, the tension disc of different size is made into cover uses.In the use, handle portion generally can not damage, and the line ball head part then causes wearing and tearing because of frequent line ball, in case after the wearing and tearing of line ball head, whole tension disc has just been scrapped, and has caused the unnecessary waste of handle.For complete tension disc, line ball head and handle are inseparable on each tension disc, therefore the line ball head on the handle can not be changed, each line ball head all has a handle, this has not only increased the raw material that produce the cover tension disc, improved manufacturing cost, but also increased the weight of every cover tension disc, the dress box carries inconvenience.

The purpose of this utility model provide a kind of on handle the composite type tension disc of the removable easy accessibility of line ball head.

The utility model is achieved in that a kind of composite type tension disc, it comprises handle and line ball head, wherein an end of said handle is connected with a tube connector, the leading section section of being threaded of tube connector, the side has cannelure, and said line ball head upper end is a cylinder, the middle part is a rectangular slab, the bottom is the platform of inverted T-shaped, and line ball head upper end places in the tube connector along the cannelure of tube connector, and by a holding screw line ball head and tube connector is connected and fixed.

In the utility model, line ball head and handle are discrete parts, according to using needs can adopt different material.The line ball head is connected with handle by tube connector, and the line ball head on tube connector for being removably connected, in case in the use after the wearing and tearing of line ball head, only need back out holding screw, change the line ball head again and can continue to use, and needn't scrap handle and tube connector.Every cover tension disc only need be established the handle of a band tube connector and holding screw, and the line ball head that is equipped with different size again gets final product, and is made into cover line ball panel material like this and economizes, and cost is low, and the suit number of packages is few, and use is carried in light weight.

Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:

Fig. 1 is a composite type tension disc structural representation;

Fig. 2 is that the A-A of Fig. 1 is to view;

Fig. 3 is the structural representation of tube connector;

Fig. 4 is that the B of Fig. 3 is to view.

As shown in Figure 1, a kind of composite type tension disc is made up of handle 1, tube connector 2, line ball head 3 and holding screw 4.Handle 1 is made by hardwood or engineering plastics.Tube connector 2 is a metal tube, and its leading section has been attacked thread segment 5, and the side has a cannelure 5(and sees Fig. 3 and Fig. 4), be furnished with corresponding holding screw 4 on the thread segment 5.Handle 1 adopts pipe injection moulding or pivot pin to be connected with 2 of tube connectors.The upper end of line ball head 3 is a cylinder, as cylinder, positive gengon or gengon, the middle part is a rectangular slab, and the bottom is the inverted T-shaped platform, and promptly the cross section upper end of line ball head 3 is round or polygonal, it in the present embodiment octagon, the middle part is rectangular, and the bottom is the (see figure 2) of inverted T-shaped, pushes the size of the end of a thread 3 bottom widths, can make 2～14mm plurality of specifications respectively, form a cover.The upper end size of line ball head 3 is complementary with the internal diameter of tube connector 2, and the middle part rectangular slab thickness of line ball head 3 and cannelure 6 width of tube connector 2 adapt.Packing in the tube connector 2 in the upper end of line ball head 3 longitudinally groove 6, and with holding screw 4 it is fixed on the tube connector 2.Finish using, unclamp holding screw 4, take out line ball head 3, the keeping of dress box.

The utility model is reasonable in design, and is simple in structure, and manufacturing materials is economized, and cost is low, carries in light weightly, uses easy accessibility.
