Technical field
The utility model is related to construction and installation field, more specifically, it relates to a kind of simple monkey wrench.
Background technology
During the removing and installing of machinery equipment, screw is often dismounted, is pulled in this case it is necessary to use
Hand.Because the diameter of the screw used is different, it is therefore desirable to use the spanner of different bores.For convenience's sake, people are frequent
Using monkey wrench come instead of using a string wrench.
Notification number is that the Chinese utility model patent of CN203141372U discloses a kind of monkey wrench, including handle, is pulled
Hand body, front clamping foot and rear pinch, the front end of wrench body are provided with hole, and front clamping foot is equipped with screw rod on top half top, has and the spiral shell
The nut that bar is used cooperatively, front clamping foot is fixed on the front end of wrench body across Kong Houyong nuts by the screw rod of front clamping foot, in spanner
Adjustment sliding slot is provided on body, rear pinch has the square slider that can be embedded in adjustment sliding slot on top half top and can pass through cunning
Block moves in sliding slot is adjusted, and sliding block top surface is equipped with screw rod, has the nut being used cooperatively with the screw rod, when sliding block is embedded in tune
Nut, which is screwed on screw rod, after whole sliding slot makes rear pinch be fixed on wrench body.
But in technical solution, in the disassembly process to equipment, need through pinch after slip and pass through nut-screw
Tighten after rear pinch is made to be fixed on wrench body, equipment could be dismounted, between adjusting between front clamping foot and rear pinch
Away from not convenient enough.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of simple monkey wrench, tool
Have and facilitate the characteristics of adjusting monkey wrench spacing.
To achieve the above object, the utility model provides following technical solution：

With the top half of the lower pinch, the upper pinch slides with the positioning pin with the lower pinch and connects.
By using above-mentioned technical proposal, positioning pin is connect respectively with upper pinch with lower pinch so that the pinch in adjustment
During lower pinch spacing, the first clamping face and the second clamping face can keep the opposite position along upper screw rod radial direction
It puts, it is no longer necessary to which control of the operating personnel to upper pinch and the relative position of lower pinch simplifies operating procedure.
Further, the top half of the upper pinch offers and matched first limit hole of the positioning pin, institute
The top half corresponding position for stating lower pinch offers and matched second limit hole of the positioning pin, the positioning pin both ends
It is respectively connected with the convex block more than its own diameter.
By using above-mentioned technical proposal, the setting of convex block can prevent positioning pin from the first limit of upper pinch and lower pinch
Position hole in the second limit hole with dropping out.
Further, positioning pin both ends outer wall offers external screw thread, and the convex block corresponding position offers described outer
The internal thread of thread fitting.
By using above-mentioned technical proposal, the threaded connection of convex block and positioning pin facilitates positioning pin and upper pinch and lower folder
The installation of foot is also convenient for the replacement in later stage.
Further, the lower screw is equipped with rubber handle far from described upper screw rod one end end sleeve.
By using above-mentioned technical proposal, operating personnel are by pulling lower screw far from upper one end end to install or remove
Bolt, while being arranged on the grasp for increasing operating personnel to lower screw of rubber handle, can also play protection operating personnel
Effect.
In conclusion the utility model has the advantages that：
1st, it is rotatablely connected by the upper screw rod of setting rotation connection, lower screw and respectively with upper screw rod, lower screw upper
Pinch, lower pinch can play the upper pinch of convenient adjusting and lower pinch spacing, and have the effect of self-locking effect simultaneously；
2nd, by sliding connection positioning pin in the upper end of upper pinch, lower pinch, the upper pinch of holding and lower pinch can be played
Along the effect of upper screw rod radial direction relative position.
