Description of reference numerals: 1-movable clamp, 2-fixed clamp, 3-clamping area, 4-first side, 5-second side, 6-first working surface, 7-second working surface, 8-main body, 9-adjusting worm wheel, 11-first clamping groove and 21-second clamping groove.

Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1, the square force-bearing adjustable wrench of the present embodiment includes a movable clamp 1 and a fixed clamp 2, and a clamping area 3 is formed between the movable clamp 1 and the fixed clamp 2. The movable clamp 1 is provided with a first clamping groove 11, the fixed clamp 2 is provided with a second clamping groove 21, the first clamping groove 11 and the second clamping groove 21 are oppositely arranged, the first clamping groove 11 and the second clamping groove 21 are both 120 degrees, and a clamping area is arranged between the first clamping groove 11 and the second clamping groove 21. Among the above-mentioned technical scheme, through setting up first double-layered groove 11 and second double-layered groove 21, can press from both sides the groove with the nut and press from both sides tightly in the centre gripping region through two to avoid the nut to skid between activity clamp and fixed clamp when twisting, avoid nut or spanner impaired. In addition, through all setting first double-layered groove and second to 120, can most hexagonal nuts on the adaptation market for there is not the clearance between double-layered groove and the nut, realize nut four directions atress, the atress face is many, and difficult slipping.

In this embodiment, the first clamping groove 11 and the second clamping groove 21 are symmetrically arranged, and the first clamping groove 11 and the second clamping groove 12 are clamping grooves with the same shape, so that the clamping grooves can clamp a hexagonal nut.

In this embodiment, the clamping groove includes a first side surface 4 and a second side surface 5, and an included angle a between the first side surface 4 and the second side surface 5 is 120 °, so that when the nut is clamped, the first side surface 4 and the second side surface 5 can be tightly attached to the nut, and thereby the four-direction stress is realized.

In this embodiment, the movable clamp 1 has a first working surface 6, the fixed clamp 2 has a second working surface 7, the first clamping groove 11 is provided on the first working surface 6, and the second clamping groove 21 is provided on the second working surface 7, so that the nut is clamped between the first working surface 6 and the second working surface 7.

In this embodiment, the square force-bearing adjustable wrench comprises a main body 8 and an adjusting worm wheel 9, wherein the adjusting worm wheel 9 is arranged on the main body 8, and the movable clamp 1 and the fixed clamp 2 are connected with the main body 8. Among the above-mentioned technical scheme, the user can drive activity clamp 1 and be close to or keep away from fixed clamp 2 through rotating adjustment worm wheel 9 to realize the clamp of nut or release. In this embodiment, the square force-bearing adjustable wrench is 8 inches, and can be applied to nuts in the range of M4-M12.

The four-side stress adjustable wrench has the advantages that when the nut is clamped, four sides are stressed, the stress surfaces are many, and the nut is not easy to slip; in addition, the clamping groove has an included angle of 120 degrees, so that a gap between the hexagonal nut and the clamping groove can be eliminated, the nut is clamped, and the nut or the wrench is further prevented from being damaged due to slipping.

It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby.
