Abstract
The utility model discloses a torsion reacting force device of a hexagon bolt spanner. The torsion reacting force device comprises a first reacting force block and a second reacting force block, wherein the upper end of the first reacting force block is provided with a hexagonal through hole corresponding to a head of the spanner; the section of the lower end of the first reacting force block is irregularly hexagonal; and the upper end of the second reacting force block is provided with a cinquefoil hole corresponding to the size of the regular hexagon of the section at the lower end of the first reacting force block. According to the torsion reacting force device, the problems of insufficient torsion, need of great acting force during screwing of a bolt, waste time and labor and low efficiency in the prior art are solved; two angles of 90 degrees are formed by the two reacting force blocks and the spanner; the moment is prolonged; higher torsion can be produced by applying the same acting force; and the required bolt can be screwed up relatively easily.
Description
Technical field
The utility model has related to a kind of torsion counter-force device of hex bolts spanner, belongs to the spanner technical field.
Background technology
As everyone knows, each parts majority of heavy mechanical equipment links together through bolt and nut, and especially hex bolts is the most commonly used.So no matter be the assembling or the dismounting maintenance of equipment; Existing spanner is normally realized the reaction force that provides to spanner through a reaction force piece; Thereby tight a bolt; When but the resistance when tighting a bolt is quite big, only be difficult to realize tightening fully to bolt with a reaction force piece.
The utility model content
The utility model technical problem to be solved provides a kind of torsion counter-force device of hex bolts spanner; Form two an angle of 90 degrees through two reaction force pieces and spanner; Be equivalent to prolong moment; Apply identical power and can produce bigger torsion, can tighten the bolt that needs relatively easily.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of torsion counter-force device of hex bolts spanner; Comprise the first reaction force piece; The upper end of said reaction force piece is provided with and the corresponding hexagon through hole of spanner rifle head; Also comprise the second reaction force piece, the following end section of the said first reaction force piece is a regular hexagon, the upper end of the said second reaction force piece be provided with one with the said first reaction force piece under the corresponding plum blossom hole of regular hexagon size of end section.
The torsion counter-force device of aforesaid hex bolts spanner is characterized in that: the lower end of the said first reaction force piece is provided with groove, and the said second reaction force piece is provided with said groove size is corresponding and is used to install the screwed hole that only attaches screw.
The beneficial effect of the utility model is: form two an angle of 90 degrees through two reaction force pieces and spanner; Prolong moment, applied identical power and can produce bigger torsion, can tighten the bolt that needs relatively easily; Through being installed in only attaching in the groove that screw is connected to the first reaction force piece on the second reaction force piece; Realization interfixes, make two reaction force pieces when tighting a bolt with a mass motion, can not break away from.

Fig. 1 is the vertical view of the first reaction force piece of the utility model hex bolts spanner;
Fig. 2 is the side view of the first reaction force piece of the utility model hex bolts spanner;
Fig. 3 is the sectional view of Fig. 1 dotted portion;
Fig. 4 is the vertical view of the second reaction force piece of the utility model hex bolts spanner.
The specific embodiment
To combine Figure of description below, the utility model will be further described.
Like Fig. 1-shown in Figure 4; A kind of torsion counter-force device of hex bolts spanner; Comprise the first reaction force piece 1, the upper end of said reaction force piece 1 is provided with and the corresponding hexagon through hole 2 of spanner rifle head, also comprises the second reaction force piece 4; The following end section of the said first reaction force piece 1 is a regular hexagon; The upper end of the said second reaction force piece 4 is provided with a corresponding plum blossom hole 5 of regular hexagon size with 1 time end section of the said first reaction force piece, and the lower end of the said first reaction force piece 1 is provided with groove 3, and the said second reaction force piece 4 is provided with said groove 3 sizes are corresponding and is used to install the screwed hole 6 that only attaches screw.
In use, the hexagon through hole 2 of the upper end of the first reaction force piece 1 is installed on the spanner rifle head, the plum blossom hole 5 of the upper end of the second reaction force piece 2 is installed in the lower end of the first reaction force piece 1; And install in the screwed hole 6 on the second reaction force piece 4 and only attach screw; And will only attach in the groove that bolt inserts the first reaction force piece 1, realize interfixing of two reaction force pieces, because the following end section of the first reaction force piece 1 is and the corresponding regular hexagon of plum blossom hole 5 sizes; When rotating the second reaction force piece 2; Plum blossom hole 5 can drive the first reaction force piece 1, thus rotating spanner, and then tight a bolt.
A second reaction force piece 2 rectangular with it is installed on the first reaction force piece 1 again, has been prolonged moment, thereby apply identical active force and can produce bigger torsion, can tighten the bolt that needs relatively easily.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain by appending claims and equivalent circle thereof.
