Abstract
The invention discloses a torque reaction force device of a hexagonal bolt wrench, which comprises a first reaction force block and a second reaction force block, wherein the upper end of the first reaction force block is provided with a hexagonal through hole which corresponds to a wrench tip; the section of the lower end of the first reaction force block is positive hexagonal; and the upper end of the second reaction force block is provided with a cinquefoil hole which corresponds to the positive hexagonal shape of the section of the lower end of the first reaction force block. According to the invention, the torque reaction force device solves the problems of great action force, time and labor waste and low efficiency due to insufficient torque in the prior art. By forming two angles of 90 DEG from two reaction force blocks with the wrench, the torque is extended; greater torque can be generated by applying the same action force; and a required bolt can be tightened relatively easily.
Description
Technical field
The present invention relates to a kind of torsion counter-force device of hex bolts spanner, belonged 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.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 invention has the beneficial effects as follows: 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. 2 is the side view of the first reaction force piece of hex bolts spanner of the present invention;
Fig. 3 is the sectional view of Fig. 1 dotted portion;
Fig. 4 is the vertical view of the second reaction force piece of hex bolts spanner of the present invention.
The specific embodiment
To combine Figure of description below, the present invention 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 of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
