Abstract

The utility model discloses a multifunction combined pincers which has a compact structure. The engagement transmission mechanism of the gear wheel and the engagement transmission mechanism of the gear wheel and the rack bar are used in the utility model. A main rod (4) drives a back lower lip (3) to rotate and drives a front lower lip (11) to move, so the pliers jaw of the pliers and the clamp mouth of a spanner can be formed, and the utility model can be used as both a pair of pliers and a spanner. In addition, the utility model can also be used as a wire stripper, an adjustable screwdriver, a pair of plastic pipe pliers, a hacksaw support frame, etc., having the advantage of multifunction.

Description

Multifunction combined pincers

The utility model relates to a kind of hand tools, especially has the combination plier of functions such as hand vice, spanner.

Existing hand tools, of a great variety, as the hand vice of gripping objects, vice, the spanner of turn nut can be peelled off the wire stripper of electric wire plastic cement crust, the movable screw of screwdriver etc. is installed is criticized, and the hacksaw support can cut off cutting pliers of wire rod such as steel wire or the like.Because above-mentioned various tool function singleness, in actual use, often to assort multiple instrument after, just can reach user's purpose, this not only spends height, and storage, use very inconvenient.

The purpose of this utility model provides a kind of multi-functional combination plier, and it can not only realize the function of common hand vice, and can also realize the function of other hand tools such as spanner.

The purpose of this utility model is achieved in that in the caliper upper end and is provided with preceding upper lip, back upper lip, has groove in the caliper.Mobile jib, prelabium, back lower lip are housed on the caliper.One end of mobile jib and back lower lip is respectively equipped with gear, and mobile jib and back lower lip are hinged by the core wheel and the caliper of two gears respectively, and above-mentioned two gears are meshing with each other.Prelabium embeds in the groove by its root, can move relative to caliper, and the prelabium root is provided with tooth bar, and this tooth bar is meshed with one of above-mentioned two gears.

Preceding upper lip and prelabium, back upper lip form the folder mouth of spanner and the jaw of pliers respectively with the back lower lip.Mobile jib rotates relative to caliper, and plier jaws and key grip are opened and closed, and clamps or unclamps object.

In the caliper lower end secondary bar is housed.

The Active Interface of flat blade screwdriver or crosspoint tip screwdriver is housed at secondary bar afterbody.Secondary bar edge is provided with profile of tooth notch and the clamping bar that is used for wire stripping, and clamping bar and secondary bar are hinged.Be provided with insert groove above the prelabium, can be used for cutting plastic tube.Mobile jib is made the shape of saw bow, and its afterbody has flanged garden post, can insert the Active Interface of secondary bar afterbody.

The utility model so can be used as pliers, can be used as spanner owing to the engagement transmission mechanism that has adopted gear and gear, wheel and rack again, and structure is compact especially.In addition, some annexes are installed on pliers, can be used as that wire stripper, movable screw are criticized, plastic pipe clamps, steelframe support etc., realization one clamps many usefulness, not only economy but also easy to use.

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

Fig. 1 is the schematic diagram according to the multi-functional combination plier that the utility model proposes; Fig. 2 is the front view of multi-functional combination plier caliper shown in Figure 1; Fig. 3 is the left view of caliper shown in Figure 2; Fig. 4 is the front view of multi-functional combination plier mobile jib shown in Figure 1; Fig. 5 is the right view of mobile jib shown in Figure 4; Fig. 6 is the front view of lower lip behind the multi-functional combination plier shown in Figure 1; Fig. 7 is the right view of back shown in Figure 6 lower lip; Fig. 8 is the front view of multi-functional combination plier prelabium shown in Figure 1; Fig. 9 is the vertical view of prelabium shown in Figure 8.

Shown in Fig. 1-9, the caliper of this multi-functional combination plier upper end is provided with preceding upper lip (9), back upper lip (2), has groove (1) in the caliper, and mobile jib (4), prelabium (11), back lower lip (3) are housed on the caliper.Back upper lip and back lower lip form the jaw of pliers, and preceding upper lip and prelabium form the folder mouth of spanner.

One end of mobile jib and back lower lip respectively is processed into the gear (23,24) of a segmental arc.Prelabium root (26) is embedded in the groove (1) of caliper, can move relative to caliper, and the root of prelabium is processed into tooth bar shape (25).Bolt or latch pass the core wheel of two gears (23,24), and mobile jib and back lower lip (3) are installed on the boss (22) on caliper groove both sides, and mobile jib can rotate relative to caliper with the back lower lip.In groove (1), gear (23) is meshed with gear (24), tooth bar respectively.When mobile jib rotated relative to caliper, gear (23) driven gear (24) rotated and tooth bar moves, and the jaw that the moving up and down of the rotation of back lower lip, prelabium makes pliers and the folder mouth switching of spanner clamp or unclamp object.

With the secondary bar (13) of mode sockets such as rivet, screw attachment (12) or welding, the caliper lower end is prolonged in the caliper lower end, increase clamping torque.

In addition, secondary bar edge has teeth groove (6), is equipped with on the secondary bar and the corresponding clamping bar of teeth groove (7), and clamping bar can rotate relative to secondary bar, after electric wire is put into teeth groove and clamped with clamping bar, can peel off the plastic cement crust of electric wire.Secondary bar afterbody is equipped with Active Interface (15), and its adjusting nut (19) lower end has 1-shaped open or cross mouth, is used to install flat blade screwdriver or crosspoint tip screwdriver.When mounting spring (14) in secondary bar, when packing ring (20) is installed in adjusting nut, Active Interface can be installed automatic swing arm (16).

On prelabium (11), have insert groove (10), behind the installation blade, can make key grip be used to cut objects such as plastic tube.

At the mobile jib neck active blade (17) is housed, is equipped with on caliper and the corresponding fixed blade of active blade (18), this can be used for cutting rigid line materials such as steel wire to cutting edge.

Mobile jib is made the shape of saw bow, its afterbody is processed into the garden post (5) that has flange, after the mobile jib afterbody inserts Active Interface (15), can between mobile jib gear end and prelabium, set up hacksaw blade, hacksaw blade is fixed by the core wheel of gear (23) and the hole (27) in the insert groove.
