Description

Extended wrench

The invention relates to a wrench, in particular to an extended type of adjustable wrench.

The existing adjustable wrench is used to cooperate with rotating bolts or nuts of different sizes. The existing adjustable wrench has a head at one end and a handle for the user to hold at the other end, wherein one side of the head is respectively provided with one a fixed type of fixed jaw, an movable jaw slidably adjustable toward the fixed jaw, and a worm rotatably disposed in the fixed jaw and engaged with the movable jaw, the fixed jaw is provided with a worm on the side The opening allows the user to rotate the worm through the opening, thereby adjusting the distance between the fixed jaw and the movable jaw, so that the existing adjustable wrench has the effect of being applicable to bolts or nuts of different sizes.

Although the existing adjustable wrench can be applied to bolts or nuts of different sizes, when the existing movable wrench is to be rotated for a bolt or a nut located in a narrow space, the handle of the existing adjustable wrench is a fixed length structural state. Therefore, it is impossible to extend the head of the existing monkey wrench in the narrow space, thereby locking or loosening the bolt or the nut, and further, when the user wants a bolt or nut for the firm screw. When loosening, the length of the existing movable wrench handle is fixed, and the torque required for the user to rotate can not be provided. Therefore, the user often needs to spend extra force to rotate, which is relatively laborious and inconvenient, and the existing adjustable wrench After the worm is processed, the two ends of the spiral teeth surrounding the worm have a tip shape, which is easy for the user to contact with the tip when turning the worm. In the case of an injured person, there are improvements.

In view of the deficiencies and shortcomings in the structure and use of the existing adjustable wrenches, the present invention has finally developed a new type that can improve the existing defects through continuous experimentation and research.

The main purpose of the present invention is to provide a movable wrench that can provide a longer length of the handle for the user to use conveniently and labor-savingly, and to design the screw of the worm into a safely usable structure. To provide a convenient, labor-saving and safe use of the wrench.

In order to achieve the above object, the present invention mainly provides a movable wrench, which comprises a handle and an operating head, wherein: the handle is provided with a body, an extension portion and a hanging hole, and the system is provided with at least one slot. The extension is formed on the body and adjacent to the at least one through hole, the hanging hole is through one end of the body; and the operating head is formed on the end of the handle different from the hanging hole and is fixed a movable cymbal and a worm, the fixed cymbal protrudingly forming the handle is different from one end of the hanging hole, the movable raft is slidably coupled with the fixed cymbal, and the worm is rotatably disposed on the shank The upper jaw is fixed and engaged with the engaging rod of the movable jaw.

Further, the length of the extension is divided by the total length of the entire spanner wrench minus the length of the extension, and the value ranges from 0.09 to 0.4173.

Further, the outer surface of the worm is formed with a spiral tooth of a circumferential shape, and the end faces of the two free ends of the spiral tooth are provided with a circular arc-shaped lead angle.

Preferably, the fixed cymbal is formed to protrude from one end of the hanging hole and is provided with a sliding slot and an opening, the sliding slot extends longitudinally through the fixing cymbal, and the opening is a through-fixing 颚a square hole on the side and communicating with the chute, the activity 颚 a slidably coupled to the fixed cymbal and having a snap-in rod extending into the sliding slot, the worm being rotatably disposed in the opening of the fixed cymbal and engaging the engaging rod of the movable cymbal .

Preferably, the system is provided with two through slots at intervals, and the extension is disposed between the two slots of the body.

Preferably, the extension portion is recessed on the outer surface with a receiving groove.

According to the above technical means, the handle of the movable monkey wrench increases the total length of the overall adjustable wrench by adding the extension to the body, which not only facilitates the user to let the activity be increased by the handle. The actuator head of the wrench can be extended in a narrow space for locking or loosening of the bolt or bolt, and at the same time, the length of the extension can be increased to increase the torque required for rotation, so that the user can save the effort in a relatively labor-saving manner. The bolts or bolts that are firmly locked are loosened. Further, the arc-shaped guide angles are respectively arranged at the two free ends of the screw teeth of the worm, so that the user can not cut the worm when the worm is rotated. In order to provide an extended type of adjustable wrench that is convenient, labor-saving and safe to use.

In order to understand the technical features and practical functions of the present invention in detail, and in accordance with the contents of the specification, the following further describes the preferred embodiment as shown in the following figure: The present invention mainly provides a movable wrench. Please refer to FIG. 1 to FIG. 3, which can be seen in the figure. The movable wrench of the present invention mainly comprises a handle 10 and an operating head 20, wherein the handle 10 is provided with a handle. The body 11 , an extension portion 12 and a hanging hole 13 , the body 11 is a handle body in a straight line shape, and the body 11 is provided with at least one through slot 14 to reduce the weight of the entire handle 10 , and further, the body The extending portion 12 is formed on the body 11 and adjacent to the at least one through slot 14 . Preferably, the extending portion 12 is disposed between the two through slots 14 . Further, the extending portion 12 is recessed on the outer surface with an elongated groove 121 extending through one end of the body 11; and the operating head 20 is formed on the handle 10 different from the hanging hole One end of the 13 is provided with a fixed cymbal 21, a movable cymbal 22 and a worm 23, wherein the fixed cymbal 21 is formed to protrude from the end of the hanging hole 13 and is provided with a sliding slot 211 and an opening 212. The sliding slot 211 extends longitudinally through the fixing jaw 21, and the opening 212 is a through hole a square hole that is disposed on both sides of the 21 and communicates with the sliding slot 211. The movable jaw 22 is slidably coupled with the fixing jaw 21 and is provided with a locking rod 221 extending into the sliding slot 211, and the worm is provided The turret 23 is rotatably disposed in the opening 212 of the fixed cymbal 21 and engages with the engaging rod 221 of the movable cymbal 22, wherein the outer surface of the worm 23 is formed with a helical tooth 24 of a surrounding shape, the helical tooth 24 The end faces of the two free ends are provided with a circular arc-shaped guide angle 241. Further, assuming that the total length of the movable monkey is L, and the length of the extension 12 is A, the length (A) of the extension 12 is divided by the activity. The value of the total length of the wrench minus the length of the extension 12 (ie, LA) (ie, A/LA) ranges from 0.09 to 0.4173.

With the above technical means, the handle 10 of the movable monkey wrench increases the total length of the overall adjustable wrench by adding the extension 12 to the body 11. Not only can the user conveniently allow the user to extend the operating head 20 of the adjustable wrench in a narrow space as shown in FIG. 4 to lock or loosen the bolt or bolt, and simultaneously Through the length of the extension portion 12, the torque required for rotation can be increased, so that the user can loosen the screw or bolt that is firmly locked in a labor-saving manner, and the screw teeth 24 of the worm 23 respectively. The two free ends are provided with arc-shaped guide angles 241, so that the user can cut the worms 23 without cutting, thereby providing a long, adjustable wrench that can be conveniently, labor-savingly and safely used.
