Summary of the invention

Technical problem solved by the invention provides and a kind ofly can change handle and the fixing spanner of angle between the spanner.

In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of spanner, mainly comprise: spanner and the handle that is arranged on the spanner lower end, be flexible connection between above-mentioned spanner and the handle, upper end at handle is provided with mounting groove, the lower end of spanner is arranged in the mounting groove by bearing pin, be provided with some teeth in the lower end of spanner, handle in the mounting groove bottom is provided with sliding pin, upper end and the tooth of sliding pin cooperatively interact, sliding pin is slidingly arranged in the cavity, on handle, also be provided with the installing hole that communicates with cavity, be provided with button in the installing hole, be provided with spring between the bottom surface of button and installing hole, the lower end of spring is arranged on the bottom surface of installing hole, and the upper end of spring is arranged in the installing hole of button lower end, be provided with opening at the button near sliding pin one side, the other end of opening and sliding pin cooperatively interacts.

In order to solve better the problem of above-mentioned technology, the further technical scheme of the present invention is: described spanner is comprised of fixing spanner and the movable jaw that matches with it, be provided with adjusting nut at fixing spanner, be provided with the adjusting screw(rod) that matches with adjusting nut in the lower end of movable jaw.

Advantage of the present invention is: the spanner of this structure can by rotating the fixedly spanner of spanner, be realized the job requirement of special occasions.

Description of drawings:

The main TV structure schematic diagram of a kind of spanner spanner of Fig. 1 the present invention open configuration.

Fig. 2 Fig. 1 left side view

Among the figure: 1, spanner, 2, handle, 3, mounting groove, 4, bearing pin, 5, tooth, 6, sliding pin, 7, cavity, 8, installing hole, 9, button, 10, spring, 11, installing hole, 12, opening, 13, fixing wrench, 14, movable jaw, 15, adjusting nut, 16, adjusting screw(rod).

The specific embodiment:

As shown in the figure, a kind of spanner, mainly comprise: spanner 1 and the handle 2 that is arranged on spanner 1 lower end, spanner 1 is by fixedly being provided with adjusting nut 15 on the spanner 13, be provided with the adjusting screw(rod) 16 that matches with adjusting nut 15 in the lower end of movable jaw 14, be flexible connection between spanner 1 and the handle 2, be provided with mounting groove 3 in the upper end of handle 2, the lower end of spanner 1 is arranged in the mounting groove 3 by bearing pin 4, be provided with some teeth 5 in the lower end of spanner 1, handle 2 in mounting groove 3 bottoms is provided with sliding pin 6, the upper end of sliding pin 6 and tooth 5 cooperatively interact, sliding pin 6 is slidingly arranged in the cavity 7, on handle 2, also be provided with the installing hole 8 that communicates with cavity 7, be provided with button 9 in the installing hole 8, between the bottom surface of button 9 and installing hole 8, be provided with spring 10, the lower end of spring 10 is arranged on the bottom surface of installing hole 8, the upper end of spring 10 is arranged in the installing hole 11 of button 9 lower ends, be provided with opening 12 at the button 9 near sliding pin 6 one sides, opening 12 cooperatively interacts with the opposite side of sliding pin 7.

The spanner of said structure, cooperatively interact to realize the folding of spanner by adjusting nut 15 and the adjusting screw(rod) 16 that is arranged on movable jaw 14 lower ends, when button 9 is not pressed, one end of sliding pin 6 stretches out cavity 7 and cooperatively interacts with the fixing tooth 5 of spanner 13 lower ends, the other end of sliding pin 6 offsets with the lower end that is arranged on the opening 12 on the button 9, makes fixedly fastened to each other between the spanner 13 and handle 2.When needs change between handle 2 and the spanner angle, only need to button 9 be pressed with hand, the other end of sliding pin 6 and the lower end of opening 12 are thrown off mutually, just arbitrarily rotary handle 2 or fixedly spanner 13, thereby change handle 2 and the fixing angle between the spanner 13, at rotary handle 2 or fixedly spanner 13 is simultaneously, an end that is arranged on the sliding pin 6 that the tooth 5 of fixing spanner 13 lower ends can will cooperatively interact with it pushes in the cavity 7, is worked in coordination in the other end of sliding pin 6 and the upper end of opening 12.Treat handle 2 and fixedly the angle adjustment between the spanner 13 well after, as long as hand is unclamped, the spring 10 that is arranged on installing hole 11 bottom surfaces can be with button 9 jack-up, thereby driving opening 12 moves up, the other end of sliding pin 7 and the lower end of opening 12 are offseted, sliding pin 6 is released cavitys 7, an end of sliding pin 6 and tooth 5 is cooperatively interacted, with handle 2 and fixedly spanner 13 be fixed together.

The spanner of said structure can be by rotating the fixedly spanner of spanner 13, so that the spanner opening is edge of a knife shape, to adapt to more job requirement.
