Abstract

The utility model relates to a spanner, in particular to an insulation adjustable spanner. The problem that a handle of an insulation spanner can not stretch is solved. The insulation adjustable spanner comprises an adjustable spanner, and further comprises a sleeve handle and an insulation sleeve, the sleeve handle is matched with an adjustable spanner handle, the insulation sleeve is matched with the sleeve handle, at least two threaded holes are formed in the adjustable spanner handle, a plurality of round holes are formed in the sleeve handle and are matched with the threaded holes of the adjustable spanner handle, and the hole spacing is equal to the empty spacing. The adjustable spanner handle is fixedly connected with the sleeve handle through countersunk bolts, and the length of the insulation sleeve is the length which is needed when the two threaded holes at the bottom end of the adjustable spanner handle are matched with the two round holes at the top end of the sleeve handle. The length of the insulation is the largest length needed, a complete insulation function is achieved, the handle can be stretched freely and operated conveniently, the countersunk bolts are used for connection, thus torque which can be born by the handle is large, the insulation adjustable spanner is easy to install, and the handle is solid.

Description

The insulation adjustable wrench

Technical field

The utility model relates to a kind of spanner, relates in particular to a kind of insulation adjustable wrench.

Background technology

In present employed Insulation spanner, has plenty of the insulating barrier of setting up, has plenty of insulation sleeve, all played good insulating effect, be " a kind of Insulation spanner " such as denomination of invention, the patent No. is the utility model patent of ZL201020611733.6, and the spanner of a kind of handle with insulation sleeve is provided, employing is socketed insulation sleeve at handle, but handle but can't extend.Because the nut that contacts with electric wire is easy to be bonded together with the bolt oxidation, dismounting needs very large moment, particularly can't change moment when the aerial operation of height, uses inconvenience, and the scope of application is narrower.

Summary of the invention

The purpose of this utility model is: too small for the too short moment that provides of the handle that has overcome original spanner, the insulation adjustable wrench that a kind of handle can free-extension is provided.

The technical solution of the utility model: a kind of Insulation spanner, comprise adjustable wrench, also comprise the sleeve handle that is complementary with the adjustable wrench handle and the insulation sleeve that is complementary with sleeve handle, the adjustable wrench handle has two screwed holes at least, and described sleeve handle has a plurality of circular holes that are complementary with adjustable wrench handle screwed hole.

Sleeve handle two circular hole spacings equate with Insulation spanner handle screwed hole spacing.

The adjustable wrench handle is connected by dormant bolt with sleeve handle.

The length of described insulation sleeve is bottom two screwed holes and sleeve handle required extreme length when topmost two circular holes cooperate of adjustable wrench handle.

The beneficial effects of the utility model: the length of freely regulating insulation adjustable wrench handle by adjustable wrench handle screw thread and the different cooperations of sleeve handle circular hole, use dormant bolt to connect so that handle is firm, the load ratio that can bear is larger, and it is convenient and simple to regulate countersunk bolt by screwdriver, insulation sleeve is installed after adjustable wrench handle and sleeve handle are worked good, and more can effectively play insulating effect; Because insulation sleeve length is the longest, can both play good insulating effect so no matter how to regulate the adjustable wrench handle with cooperating of sleeve handle.
