Description

It is a kind of to adapt to strong Chain wrench
Technical field
The utility model relates to a kind of Chain wrenches, in particular to a kind of to adapt to strong Chain wrench.
Background technique
Spanner is common hardware tool, is generally used for tightening non-circular workpiece, such as nut, nut, has behaviour Facilitate, it is time saving and energy saving the advantages that.
Currently, common spanner is there is also some disadvantages, and first, current spanner can typically be only used to tighten with angle The workpiece of (or screw thread), incapability is if not having angular workpiece (such as round steel pipe, round nut etc.) for some circles, arcwall face etc. Power;Second, current adjustable wrench needs to adjust the jaw size of spanner by worm screw, inconvenient in operation, in addition, pulling sometimes The pushing time is not used, and worm screw may be difficult to rotate because getting rusty;Third, current spanner, which is not only typically only capable to be directed to, angle The workpiece of (or screw thread), durable general adaptation range is lesser, and big workpiece needs big spanner that could operate, to give user Carrying, using bringing inconvenience.
It is accordingly required in particular to a kind of adapt to strong Chain wrench, it is above-mentioned existing to solve the problems, such as.
Utility model content
Strong Chain wrench is adapted to the purpose of this utility model is to provide a kind of, in view of the deficiencies of the prior art, can be fitted Answer the workpiece of various specifications and shape, simple structure and reasonable design, using more convenient.
The technical issues of the utility model is solved can be realized using following technical scheme:
It is a kind of to adapt to strong Chain wrench, which is characterized in that it includes extension bar, locking chain, jam plate and locking chain Fixed mechanism, the jam plate is fixed on the extension bar and the front end of the extension bar is stretched out in the front end of the jam plate, described One end of locking chain is fixed on the jam plate, the other end of the locking chain around the jam plate front end and around to institute It states on extension bar, the locking chain is fixed on the extension bar by the locking chain fixed mechanism, the jam plate Front end and the locking chain between formed to the accommodating space of workpiece.
In one embodiment of the utility model, the jam plate is welded on the front end of the extension bar, in the jam plate Side be provided with a lock ear stretched out outwardly, one end of the locking chain, which is fixed on formation in lock ear by a lock pin, to be turned Dynamic structure.
In one embodiment of the utility model, the locking chain fixed mechanism includes a lock tube and jackscrew, institute The side that lock tube is welded on the extension bar is stated, the jackscrew is threaded on the lock tube, and the locking chain is along the side of extension bar Face passes through lock tube, and will lock chain by tightening jackscrew is locked with extension bar, so that jam plate be cooperated to bind workpiece.
In one embodiment of the utility model, the front end face of the jam plate is equipped with anti-skid teeth, and workpiece withstands on described anti- It is locked in sliding teeth by the locking chain, prevents workpiece from skidding, make to bundle stronger.
The strong Chain wrench of the adaptation of the utility model passes through locking chain and jam plate phase interworking compared with prior art After conjunction bundlees workpiece, then chain will be locked with jackscrew and will be lockked, can turn workpiece by the way that extension bar is positive and negative, reach elastic mesh , it may be not only suitable for the workpiece of numerous different sizes and shapes, such as round tube, nut, the tools such as alternative spanner, pipe wrench, It is easy to carry, and operation is simpler, improves work efficiency, and realizes the purpose of this utility model.
The characteristics of the utility model, sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clear Ground understands.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the strong Chain wrench of the adaptation of the utility model.
In figure: 1- lock ear, 2- lock pin, 3- locking chain, 4- workpiece, 5- anti-skid teeth, 6- jam plate, 7- extension bar, 8- lock tube, 9- jackscrew.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.
Embodiment
As shown in Figure 1, the Chain wrench that the adaptation of the utility model is strong, it includes extension bar 7, locking chain 3, jam plate 6 With locking chain fixed mechanism, jam plate 6 is fixed on the front end that extension bar 7 is stretched out on the extension bar 7 and front end of jam plate 6, locking chain One end of item 3 is fixed on jam plate 6, the other end of locking chain 3 around jam plate 6 front end and around on extension bar 7, locking chain Item 3 is fixed on extension bar 7 by the locking chain fixed mechanism, formation pair between the front end and locking chain 3 of jam plate 6 The accommodating space of workpiece 4.
The strong Chain wrench of the adaptation of the utility model, handle main body of the extension bar 7 as spanner.
In the present embodiment, jam plate 6 is welded on the front end of extension bar 7, and the side of jam plate 6 is provided with one and stretches out outwardly Lock ear 1, one end of locking chain 3 is fixed in lock ear 1 by a lock pin 2 forms turntable;It can be increased by lock ear 1 Workpiece 4 so as to adapt to bigger workpiece, and can be locked tighter, while also make to operate more convenient by torque.
