Abstract

The utility model relates to a shuttle forming integral hand tool. A slot part is arranged on a female handle joint. A shaft centre hole is arranged on the slot part, and an impact conical member is penetrated into the slot part and is pressed to expand the slot part, which causes the slot part to become an expansion slot part. A shaft center is arranged in the position of a male handle, and the position of the male handle is relative to the shaft centre hole of the slot part of the female handle. The male handle is penetrated from the expansion slot part of the female handle, and the shaft centre of the male handle is aligned to the shaft centre hole. Two flat iron sheets are tightly pressed on the expansion slot part of the female handle, so that the shaft centre hole of the female handle is sheathed into the shaft center to form a hand tool for integral form of the male handle and the female handle. The tool has the advantages of steady structure, difficult looseness, high accuracy and good practicability.

Description

Shaping integrated hand tools can shuttle back and forth

The utility model relates to hand tools, relates in particular to a kind of shaping integrated hand tools that shuttles back and forth.

Consult Fig. 1, Fig. 2, shown in Figure 3, commonly use hand tools, be that axle center hole 12 and screw part 13 cooperations that utilize male and female lever 10,11 to be oppositely arranged screw togather element 14 lockings, this structure except that the steadiness that causes hand tools inadequately, also can reduce its precision, therefore be not suitable for the industry of precise operation, practicality is relatively poor, its shortcoming: 1, robustness is not high.Because the hand tools of commonly using is to utilize the screw locking mode to reach the structure of locking, this structure coping screw causes tolerance when locking easily, or driving fit locking fully in twos, so its steadiness is quite low, causes also lower service life thereupon; 2, precision is low.Commonly use hand tools often along with the increase of frequency of utilization; regular meeting's generation screw gradually gets loose and is difficult for the situation of interlock; or cause the gap; inhomogeneous or the gapped structure of this interlock is easy to cause the clamping position 101,111 of male and female lever 10,11 not tight, quite is not suitable for the very tight medical hand tools of some precision.

Consult Fig. 4, shown in Figure 5, in order to design a kind of one-body molded and hand tools structure that steadiness is higher, someone utilizes the portion that covers 102 of cutting female lever 30, and after treating public lever 20 closings, give bonding its of high pressure again and cover portion 102, but such structure can be destroyed original framework equally, though it is difficult for finding out the abutment from the teeth outwards, uses long afterwards and still can chap at the abutment.Therefore, can no matter be that high pressure is bonding, still utilize the structure of carbon dioxide electric welding welding completely, all not have steadiness equally to learn.

In view of this, this creator is according to being engaged in the experience of making this product for many years, and actively researchs and develops, and designs the utility model finally.

Main purpose of the present utility model is, a kind of shaping integrated hand tools that shuttles back and forth is provided, and makes its manufacture process easy.

Another purpose of the present utility model is, a kind of shaping integrated hand tools that shuttles back and forth is provided, and its robustness is improved, and need not do the covering action, destroys overall structure.

Another purpose of the present utility model is, a kind of shaping integrated hand tools that shuttles back and forth is provided, and its precision is improved, and the structure that is formed in one, and the interlock degree of pivot is quite high, the unlikely generation situation that gets loose.

The purpose of this utility model is realized by following technical scheme.

The utility model shaping integrated hand tools that can shuttle back and forth, it mainly comprises a male and female lever, its improvements are, this mother's lever joint is provided with a slot part, this slot part is provided with an axle center hole, and utilizes one to collide the awl part and penetrate in the slot part, and the application of force struts and makes its slot part be one to expand slot part; This public affairs lever is provided with an axle center with respect to the slot part axle center hole place of female lever, and public lever penetrates from the expansion slot part of female lever, and make its axle center alignment axle center hole, the iron plate on two planes closely presses the expansion slot part of female lever, its axle center hole is inserted in the axle center, becomes the shaping integrated hand tools of male and female lever.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Consult Fig. 6 to shown in Figure 10, the utility model shaping integrated hand tools that can shuttle back and forth, it mainly comprises a male and

female lever

20,30, the joint of this mother's lever 30 is provided with a slot part 31, this slot part 31 is provided with an axle center hole 32, and utilize one to collide awl part 33 and penetrate in the slot part 31, and the application of force strut and makes its slot part 31 be one to expand slot part 311 (shown in Figure 7); This public affairs lever 20 is provided with an axle center 21 with respect to slot part 31 axle center holes 32 places of female lever 30, and the expansion slot part 311 of public lever 20 from female lever 30 penetrated, and make its axle center 21 alignment axle center holes 32 (shown in Figure 8), utilize the iron plate 40 on two planes closely to press the expansion slot part 311 (shown in Figure 9) of female lever 30, its axle center hole 32 is inserted in the axle center 21, become male and

female lever

20,30 shaping integrated hand tools (shown in Figure 10), it has higher industrial utilization.

From the above, the utility model shaping integrated hand tools that can shuttle back and forth, it is using The time do not commonly use the shortcoming that hand tools exists fully, and can make hand tools more firm And have multiple variation, so that its scope of application is extensive, and have better industrial utilization. For making the auditor can be well understood to the effect that the utility model can reach, hereby that its advantage is total Tie as follows: 1, manufacturing processing is easy. It is utilize cylinder with female lever front end in conjunction with perforate The place struts, so that male lever front end bearing can penetrate female lever front end in conjunction with tapping, and makes The in addition interlock of the junction of male and female lever front end need not to destroy original structure, so its It is very easy to make processing. 2, robustness height. It need not destroy body construction, becomes one Therefore the structure of moulding does not have the problem that gets loose. 3, precision height. It utilizes processing machine Closely die casting even overexertion still can be carried out the accurate thing of getting and move, does not have fully The offset issue of angle.

In sum, the utility model shaping integrated hand tools that can shuttle back and forth, it is by an iron prop Body struts action and has novelty with the design that reaches firm effect; It adopts and does not destroy the worker Tool is the method for structure originally, reaches the high purpose of precision, and reduces manufacturing cost, uses effect Fruit is desirable, makes it have practicality; This project organization does not see any publication, and on the market also Have no any class time product, therefore had novelty, met the application important document of utility model.
