Description

a wrench

technical field

The invention relates to a wrench which can be used with different types of nuts or bolts and is easy to operate and portable.

Background technique

Screws can be seen everywhere in life and industry, and the scope of use is also very wide. We use screws in every aspect of our life. When disassembling these bolts or nuts, we must use a wrench to complete the purpose of disassembly. The position of the wrench is different, and the model of the nut or bolt is also very different. At present, the design of some wrenches is still limited by the model, and cannot match a variety of models. Too many tools are not easy to use and carry, so there are always some wrenches that cannot be found. When matching wrenches, for the convenience of use, it can match different types of nuts or bolts wrenches, whether in industrial production or in life, it is more convenient for everyone to use.

Contents of the invention

The object of the present invention is to provide a wrench that can be used for internal and external hexagonal screws, is easy to operate, and is portable in order to overcome the deficiencies of the prior art.

In order to achieve the above object, the technical solution adopted by the present invention is: a wrench, including a working grip, a tapered rod and a torsion rod; six slide grooves are evenly distributed on the tapered surface of the tapered rod; The other end is connected with the torsion bar; there are six working grippers; the working gripper is set in the chute; the working gripper set in the chute has threads; It is a fastening head; the outer sleeve of the working gripper is provided with a rotary nut; the rotary nut is composed of two semicircles and connected by screws.

Preferably, the inner surface of the fastening head is a concave angle of 120°.

Preferably, a swivel groove is arranged on the chute.

Preferably, the torsion bar is connected to the tapered rod through a rotating shaft, and the torsion bar rotates around the rotating shaft.

Preferably, the torsion bar is provided with a groove whose shape matches the tapered bar.

Preferably, a rotary plate is also provided on the rotary nut.

Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

A wrench according to the present invention can adjust the size of the working grip by adjusting the rotary nut, so that the fastening head can fasten different types of nuts or bolts to complete the disassembly and assembly action, and the angle of the torsion rod and the tapered rod can be changed, which is more convenient. It is easy to operate, and can also be folded, easy to carry, suitable for various models and occasions, and has strong practicability.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Accompanying drawing 1-3 is a kind of wrench described in the present invention, comprises working gripper 1, conical bar 2 and torsion bar 3; According to equilateral triangle stability is the best, here conical bar 2 taper design is 60 degrees, The conical surface of the tapered rod 2 is evenly distributed with six chutes 4; the chute 4 is provided with a revolving groove 8, and the revolving groove 8 crosses with the chute 4; the other end of the tapered rod 2 is connected to the torque The rod 3 is connected; the torsion rod 3 is connected with the tapered rod 2 through the rotating shaft 9, and the torsion rod 3 rotates around the rotating shaft 9; the torsion rod 3 is provided with a groove whose shape matches the tapered rod 2; the working There are six grippers 1; the working gripper 1 is arranged in the chute 4; the working gripper 1 arranged in the chute 4 has threads 5; Fixing head 6, the inner surface of the fastening head 6 is a concave angle of 120°; the outer side of the working grip 1 is provided with a rotary nut 7; the rotary nut 7 is composed of two semicircles, and is connected by screws; A protruding rotary plate 10 is also provided on the rotary nut 7 .

The working gripper 1 can slide in the chute 4 to adjust the length of the working gripper 1, hold the rotary plate 10 on the rotary nut 7, and the rotary nut 7 can move on the thread 5 of the working gripper 1, thereby adjusting The size of the fastening head 6, the rotary nut 7 moves within the limit of the rotary groove 8, according to different types of nuts or bolts, turn the rotary nut 7 to adjust the fastening head 6 to a suitable size, the inner surface of the fastening head 6 is 120° concave angle and tighten it, then rotate the torsion bar 3 around the rotating shaft 9 to a suitable angle, and turn the torsion bar 3 hard to drive the working handle 1 to turn the nut or bolt to realize the installation and disassembly action, when the use is completed Finally, turn the torsion bar 3 so that the groove on it overlaps with the tapered bar 2 to make it foldable and easy to carry. The working grip 1 can be matched with various types of nuts or bolts, and the number of tools used is less, which is convenient and practical .

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention. Substantial equivalent changes or modifications shall fall within the protection scope of the present invention.
