Embodiment 1

[0018] figure 1 The described adjustable wrench This adjustable wrench has a handle 8, a wrench body 7, a fixed open tongue 3, a movable open tongue 1, a turbine knob 10 and a fixed pin 12, the handle 8 is integrated with the wrench body 7 and the fixed open tongue 3, and the movable open tongue 1. The moving tooth bar 13 is fixed, and the moving tooth bar 13 is installed in the tooth bar hole 14 of the wrench body 7. The movable opening tongue 1 is opposite to the fixed opening tongue 3 and installed on the wrench body 7 through the moving tooth bar 13. The turbine knob 10 is fixed by The pin 12 is installed in the knob groove 16 of the wrench body 7, and the helical tooth 11 of the worm gear knob 10 meshes with the tooth 15 of the moving rack 13. The hammer 4 with 3 tongues is integrated, and a notch 6 is arranged at the joint between the root of the hammer 4 and the moving tooth bar 13, so as to ensure that when the moving opening tongue 1 and the fixed opening tongue 3 are...

Embodiment 2

[0021] The difference between this embodiment and embodiment one is that the screwdriver at the lower end of the handle 8 is a cross-shaped screwdriver 17, see image 3 . Other structures of this embodiment are the same as those of Embodiment 1.

Abstract

This invention relates to an adjustable spanner, which comprises a handle, a spanner body, a fixed opening tongue, a mobile opening tongue, a turbine knob and a fixing pin. The handle, the fixed opening tongue and the spanner body are integrated; the mobile opening tongue is fixed with a mobile gear rod; the mobile gear rod is arranged in a worm hole of the spanner body; the mobile opening tongue and the fixed opening tongue are arranged on the spanner body by the mobile gear rod; the turbine knob is arranged in a knob groove of the spanner body through the fixing pin; and the helical teeth of the turbine knob are meshed with the teeth of the mobile gear rod. The adjustable spanner is characterized in that: a hammer integrated with the fixing opening tongue is arranged on the outer part of the fixing opening tongue of the spanner body; and a groove is reserved at a joint between the root part of the hammer and the mobile gear rod. A straight or crossed groove screwdriver can be arranged at the tail end of the handle. The spanner can replace the hammer for beating and can replace the screwdriver for screwing.

Description

technical field [0001] The invention relates to an adjustable wrench. Background technique [0002] In the working process of using the adjustable wrench, it is sometimes necessary to knock. Generally, people habitually use the wrench instead of the hammer to knock, causing the movable worm hole of the wrench head to be deformed due to impact and cannot be used normally, shortening the service life of the wrench. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing adjustable wrench, the present invention provides an adjustable wrench that can replace the hammer. [0004] The adjustable wrench includes a handle, a wrench body, a fixed tongue, a movable tongue, a turbine knob and a fixed pin. The handle is integrated with the wrench body and the fixed tongue. In the worm hole of the worm, the movable opening tongue and the fixed opening tongue are installed on the wrench body through the moving gear rod, and the turbine k...
