Description

[Detailed description of the invention] Anti-stick pliers Technical field The present invention is designed to be used for fixing reinforcing bars or reinforcing bar mats in construction work. This relates to locking pliers. This fixation is done with a relatively thin wire.

The wire is wrapped around the rebar, twisted and then cut with pliers. like this When using pliers, everything in a space that is structurally made of reinforcing steel. It must be possible to reach the location. Therefore, construction work called reinforcing bar work The construction worker must be able to insert the pliers into the rebar body. this has enough free air to insert cinch pliers between each outer reinforcing bar. The condition is that there must be a gap. In addition, the << anti-stick pliers are Also. It fits comfortably in your hand so that you can operate it without tiring your hand. It has to be something special.

Conventional technology As is well known, the generally known pliers-like claw consists of two bar-shaped parts. Locking pliers are used. The two rod-shaped parts are connected to each other by a joint.

In this case, on one side of the coupling both free ends of the pliers are formed as jaws and The two opposite free ends of the lyre are configured as grips. both grills The cups move away from each other in a V-shape towards their free ends. This tie-stop In the case of pliers, when opening the pliers to pinch the stopper wire, the grip Since the pliers are open to each other in a V-shape, the pliers are compatible with the inside of the cage-shaped reinforcing bar assembly. Requires a large amount of free space, so it cannot be used in narrow squirrel cage or similar reinforcement In some cases, operation can be extremely difficult. However, this free space is not always available structurally, so in such cases, The pliers can be turned around its longitudinal axis between said or said reinforcing bars. In this way, the reinforcing bars must be pushed apart from each other. moreover, In the open position, the grips of these detent pliers spread very widely apart from each other. Therefore, in this open state, the pliers cannot be gripped with only one hand.

Description of the invention Starting from this prior art, the present invention does not have the disadvantages mentioned in the above prior art. Therefore, in general, for the fixation of all reinforcing bars in a reinforcing structure, especially on the lower or rear side. tying pliers of the type mentioned at the beginning, which are ideal for fixing reinforcing bars in The invention has the features of claim 1. Therefore, it is also known from the prior art This clipping pliers should be used when the jaws of the clipping pliers are closed. when both grips abut each other in a V-shape at the joint point and intersect there. The intersection of the grips exists only at a certain distance from the joint, without It is superior in that both grip portions adjacent to the fitting are shaped to ing. Therefore, the grip adjacent to the fitting with respect to the centerline passing through the fitting Each jaw part that is connected to each part is attached to a stopper like this. located on the same side in plan view, i.e. on the right or left side of the .

When the declutching pliers are opened, the grips held by a person's hands may touch each other. When opened, the grip part connected to the fitting will therefore have a projection line that includes the jaws. It does not swing out of the way. Therefore, such (de-clamping pliers) It can be inserted into the reinforcing steel whenever its closed jaws can pass through the existing gap. Become. Therefore, the tying pliers according to the present invention can achieve extremely high productivity. It is extremely advantageous from an economic point of view. Rationalization measures and In construction sites where measures to improve productivity are extremely desirable, the present invention is suitable ( Significant benefits can be obtained with locking pliers.

Further advantages and features of the locking pliers are disclosed in the dependent claims and It will become clear from the explanation below.

Brief description of the drawing The invention will be explained in more detail below by means of illustrated embodiments. Figure 1 is now open. FIG. 2 is a plan view of the clipping pliers of the invention in the closed state FIG. 1 is a plan view of the clipping pliers shown in FIG.

Examples of the invention The clipping pliers 10 are configured symmetrically with respect to the center line 12 in plan view. There is. The left jaw portion 14 and the right jaw portion 16 are on the centerline 12 and, for example, They are swingably connected to each other within a joint 18 formed by bolts etc. Ru. The front ends 20 of both jaws 14.16 are clamped by these jaws. The detent wire is shaped like a blade so that it can be cut as lightly as possible. .

In the plan view, the left grip portion 22 is fixed to the left jaw portion 14 on the lower side of the joint 18. ing. This grip portion 22 is integrally connected to the left jaw portion 14. Correspondingly The right grip portion 24 is similarly fixed to the right jaw portion 16 (X). The expressions "and right" are used here and below as The component may exist on the left (L) or right (R) of the center line 12 in the plan view. means.

Both grip portions 22 and 24 are substantially straight in their intermediate region. and open slightly towards each other towards the lower ends of the pliers. ((the law of nature When the stop pliers 10 are in the closed position (FIG. 2), the grip portions 22.24 The maximum mutual distance is - in this example the corresponding maximum of the left and right jaws 14.16. It is about the same size as the great mutual distance. This mutual distance ↓11. X-shifted case also has a value of d. Therefore, - as shown in FIG. (The fixing pliers 10 can be inserted securely into the reinforcing bar assembly, and Whenever the jaws 14 and 16 of the chiseling pliers can fit into the existing reinforcing bar gap, It is possible to insert the rosette securely.

In the lower area of the left and right grip parts 22.24 they are closer to each other. 9 and intersect in the area of position 26. in this position 26) The grip portions 22, 24 on the other hand overlap each other. Place @26) and left A right grip 28 is attached to the grip portion 22, and a left grip 30 is attached to the right grip portion 24. force (connected. Grip 28 and grip 30 are (forms the region of the clipping pliers 10).

In this example both grips 28.30 have a width greater than d (, x maximum mutual A distance 11D is shown. The lower areas of both grips 28.30 are parallel to each other ↓ ).

The cross sections of the right grip 28 and the left grip 30 have a substantially circular shape.

Therefore, in this clipping pliers, the left jaw portion 14. left grip part 22 and right grip 28 are integrally coupled. Correspondingly, the right jaw area 16. The right grip portion 24 and the left grip 30 are also joined together. crossing At position 26 of the area 1 both grip parts 22.24 to right grip 28 and left grip 30 intersect in the area of center line 12.

As already mentioned, both jaws 14.16 passed through the gaps in the existing reinforcing bars. At any time, it can be inserted into at least the area of position 26 into cage-shaped reinforcing bars etc. It is. When opening this pliers 10, the grips 28 and 30 are on the outside. the jaws 14.16 also open outwards. In this case left and right grip The portions 22 , 24 approach each other, ie in the direction of the center line 12 . therefore, The mutual distance of the two gripping parts 22,24 is reduced (FIG. 1). therefore, This part of the declutching pliers 10 is formed by the left and right grip portions 22,24. area is not obstructed within the area of the squirrel cage reinforcement. -as above- As long as the pliers 10 can be inserted into the cage-shaped reinforcing bar set, the pliers 10 can always be opened in its inserted state.

When the pliers are closed, the right and left grips 28.30 are approximately flat with each other. Because the grips are arranged in a straight line, both grips do not spread out that much. Therefore, the locking pliers 10 pose a problem even when they are in the open position (they cannot be grasped with one hand). is possible.

In the above, we have described the tying pliers, but this tying pliers All kinds of pliers that require enlarged free space when opening it It should be understood that this applies to
