Abstract

The utility model relates to a universal wrench for tightening and pulling open the grinding disc of an angle grinder. The universal wrench is made up of a handle, a fixed wrench head and a movable wrench head; the fixed wrench head is connected into a whole with the handle directly, and the rear end of the movable wrench head is pivotally connected with a pin shaft hole of the fixed wrench head through a hinge pin, thereby forming a structure that a distance between a wrenching piece at the front end of the movable wrench head and a wrenching piece at the front end of the fixed wrench head is adjustable. The utility model has the advantage of adjustable wrenching distance of the wrench, and therefore is adapted to various grinding discs with different wrenching holes spaces.

Description

A kind ofly be used for the general utility wrench that angle grinding machine mill is tightened, pulled open

Technical field

The utility model relates to a kind of manual apparatus, specifically, is a kind of general utility wrench that angle grinding machine mill is tightened, pulled open that is used for.

Background technology

Two stubborn holes of pulling are arranged above the grinding machine mill of angle, and the angle grinding machine need be tightened in mill on the grinding machine of angle by being exclusively used in the spanner of tightening mill before using, after using a period of time, because the wearing and tearing of mill, mill needs to change, at this moment, must mill be pulled open from the angle grinding machine by this spanner again.

At present, it is known that to be used for the general utility wrench that angle grinding machine mill tightens, pulls open be the fixing fixedly spanners of two spacings, but, the used mill of different angle grinding machines can be different because of different two the stubborn spacing of pulling the hole of size specification, simultaneously, even use the angle grinding machine of onesize specification mill, also may be because of the mill that adopts different manufacturers to produce, can be different and make two of mill twist the spacings of pulling the hole.

Like this, the user of angle grinding machine just has to be equipped with the mill spanner of multiple spacing, uses extremely trouble.

Summary of the invention

The purpose of this utility model is at the problems referred to above, thus provide a kind of regulate to twist pull spacing and adapt to the various general utility wrenches that angle grinding machine mill is tightened, pulled open that are used for that the mills of pulling pitch of holes use of twisting.

The purpose of this utility model is achieved in that by handle, fixedly spanner and movable jaw are formed; Fixedly spanner and handle directly fuse, the rear end of movable jaw by bearing pin and fixedly the pin shaft hole of spanner articulate, and constitute the stubborn pull piece of movable jaw front end and fixing stubborn pull piece stubborn the pulling between the two of spanner front end apart from the structure that can regulate.

The utility model, bearing pin are connected with the set screw that is used to compress movable jaw.

The utility model, handle are provided with injection moulding assurance portion.

The utility model, injection moulding assurance portion is provided with and holds recess, is convenient to hold.

The utility model, thus the stubborn various advantages of pulling the different mill of pitch of holes of twisting of pulling spacing adaptation angle grinding machine of adjustable spanner had.

Following embodiment accompanying drawings is further described the utility model.

The specific embodiment

With reference to Fig. 1, knownly be used for the spanner that angle grinding machine mill is tightened, pulled open, the stubborn spacing of pulling of its spanner is a fixed range and unadjustable, a spanner can only be used for a kind of twisting and pull the identical mill of spacing.

With reference to Fig. 2 to Fig. 3, present embodiment is a kind of general utility wrench that angle grinding machine mill is tightened, pulled open that is used for, by the handle 1 that is provided with injection moulding assurance portion 6, fixedly spanner 2 and movable jaw 3 are formed; Fixedly spanner and handle directly fuse, this injection moulding assurance portion 6 is provided with and holds recess 7, the rear end 31 of movable jaw is by bearing pin 4 and fixedly pin shaft hole 21 pivot joints of spanner, bearing pin 4 is connected with the set screw 5 that is used to compress movable jaw, after unclamping set screw, can regulate easily to twist and pull distance A.

With reference to Fig. 4, the stubborn pull piece of movable jaw front end 32 can be regulated with the fixing stubborn pull piece 22 stubborn distance A of pulling between the two of spanner front end.

Assembling of the present utility model:, the rear end 31 of movable jaw by bearing pin 4 and fixedly pin shaft hole 21 installings of spanner, articulates both and gets final product with reference to Fig. 3.
