Description

Combined adjustable portable disassembling and assembling device

The utility model relates to a kind of instrument of auto trade, refers to a kind of portable replacer that is used for the porthole place under repair especially.

The most difficult problem that often runs in the vehicle maintenance and repair process at present is exactly the dismounting of porthole, because modern automobile is brought in constant renewal in and is improved, especially at exhaust emissions, parts configuration aspects lubricated and combustion chamber is improved, so the automobile cylinder cap of a lot of countries changes the matrix formula into by plane formula, like this to having played very good effect the service life of the lubricated of valve mechanism and prolongation parts, but because the improvement of cylinder cap, the spring of porthole is all below porthole chamber cap plane, adding the structure compression volume and dwindle, is again tilting porthole, has just brought very big difficulty to porthole dismounting in the present motor repair trade, particularly be in repair procedures, if operation or instrument are improper, careless slightly, Valve stem will be damaged, also have the phenomenon of hurting sb.'s feelings when mounted, also can cause the waste on unnecessary loss and the material.

Goal of the invention of the present utility model is the problem at above-mentioned existence, and it is not only convenient but also reliable, time saving and energy saving to disclose a kind of use, the combination adjustable and portable formula porthole replacer that can greatly increase work efficiency.

Provide concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

See also accompanying drawing, technical solution of the present utility model is: the end at hollow cylinder 1 slidably is provided with nut discount 2, the other end of cylinder 1 is provided with the adjusting device that makes nut discount 2 elastic, be fixed with a fixed arm 3 on cylinder 1 outside wall surface, be movably equipped with the adjusting lever 4 of a hollow on the fixed arm 3, one end of the top arm 5 of inverted L shape is connected with adjusting lever 4, is nested with the top 6 of a removable position on the other end of top arm 5.

Above-mentioned adjusting device is air inlet pipe 7, and air inlet pipe 7 one ends are connected with hollow cylinder 1, and the other end is provided with air inlet 8 and switch handle 9. Gases at high pressure enter cylinder 1 through air inlet pipe 7, push away before forcing nut discount mouth, then removable cylinder valve etc.

Above-mentioned control apparatus is for to be provided with a leading screw in cylinder 1, an end of leading screw withstands on an end of nut discount 2, and the other end of leading screw stretches out cylinder 1, establishes a crank on it, shakes crank, then can make nut discount 2 flexible.

Have a groove on the above-mentioned fixed arm 3, then adjusting lever 4 can move on fixed arm 3, the distance between adjustment and the cylinder 1.

Above-mentioned adjusting lever 4 is a hollow, and an end of top arm 5 can stretch in adjusting lever 4, adjusts the distance between top 6 and the nut discount 2, upper and lower displacement can be done in top 6 on top arm, do the small distance adjustment to coming directly towards 6 with the center of nut discount, cooperate, then be easy to use with adjusting lever 4.

When the utility model uses, withstand an end of split inloading part, make the nut head flexible by setting device, then can dismantle easily, because adjusting lever 4, top arm 5 and top 6 all can be in the enterprising row distance adjustment of direction separately, so be fit to multiple situation, be very easy to use, simultaneously all dismounting at any time of each parts, so be easy to carry, and it is simultaneously time saving and energy saving that work efficiency is greatly improved.
