Description

Spanner

Technical Field

The utility model relates to a hand tool field especially relates to a spanner of twisting the operation soon suitable for car field and daily most of conventional nut, bolt.

Background

The existing spanners are classified finely, such as a dead end spanner, a ring spanner, a ratchet spanner, a socket spanner, a monkey wrench and the like, the functions of the spanners are single, and the spanners cannot be used in a mixed way and are not universal among all kinds of spanners. Various wrenches have various characteristics and obvious defects. For example, a dead end wrench and a box end wrench are convenient and easy to use, but cannot be adjusted, and a set of a plurality of handles needs to be prepared; the ratchet wrench is convenient and labor-saving, but mostly cannot be adjusted, and cannot be used for places with small working surfaces, such as nuts at a deeper position; the socket wrench can work in a complex environment, but is not adjustable like a solid wrench, is mostly in a three-fork or cross shape, has large volume and is not easy to retract; the adjustable wrench is adjustable, but like a ratchet wrench, does not have much use for deep nuts. This often results in confusion when selecting tools, and often the inconvenience of preparing various wrenches for occasional use.

Disclosure of Invention

The utility model aims to overcome all kinds of spanner technical not enough, improve and understand again the structure of spanner, provide a bolt and nut's spanner suitable for different specifications.

In order to achieve the purpose, the wrench provided by the utility model comprises a handle, a working claw, an adjusting piece, a return spring and a sleeve, wherein the handle is provided with a groove, the adjusting piece is axially and limitedly arranged in the groove and can move transversely relative to the handle, and a bulge is arranged on the adjusting piece; the return spring is arranged between the bottom wall of the groove and the adjusting piece; the sleeve is used for sleeving the handle and the adjusting piece in the sleeve and can axially move relative to the handle, and is provided with a chute for placing a protrusion on the adjusting piece, and the chute is inclined in the height direction of the sleeve; wherein, the working claw comprises a fixed claw arranged at the end part of the handle and a movable claw arranged at the end part of the adjusting piece.

The utility model discloses a spanner adjusts the position of movable claw through back-and-forth movement sleeve, has realized the regulation of spanner shifting gate size to adapt to the bolt of different specifications, nut, it is simple convenient, saved the trouble of carrying various spanners, it is all very convenient to carry and use.

Furthermore, the handle is provided with a sleeve hole, the wrench also comprises a grab handle and a connecting rod, the connecting rod is rotatably connected with the handle and the grab handle, and one end of the grab handle can be inserted into the sleeve hole.

The utility model utilizes the folding technology, one end of the grab handle can be inserted into the trepanning under the working state, so as to increase the moment and save the physical strength; also can hold the handle and lean on the handle to place under the state of awaiting the job, save space, portable and deposit.

Drawings

FIG. 1 is a perspective view of a wrench;

FIG. 2 is an exploded view of the wrench;

fig. 3 is a working state diagram of the wrench.

The present invention will be described in detail with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1 and 2, the wrench includes a handle 1, an adjusting member 2, a return spring 3, a socket 4, and a grip 5. Two fixed claws 71 are arranged at one end of the handle 1, a trepan 11 is arranged at the other end, and a groove 14 is further arranged at the position close to the fixed claws 71. The adjusting member 2 is placed in the groove 14 and cannot move in the axial direction relative to the handle 1, but can move up and down in the transverse direction of the handle 1 relative to the handle 1. The adjusting member 2 is provided with a projection 21 and a moving claw 72 at the end. The fixed jaw 71 and the movable jaw 72 form a wrench tap for nesting a bolt or a nut, the size of which can be adjusted by the up-and-down movement of the adjusting member 2. The return spring 3 is arranged between the adjusting member 2 and the bottom wall of the recess 14. The sleeve 4 comprises a mounting 41, the mounting 42 being arranged relatively stationary inside the sleeve 4 and being immovable and rotatable relative to the sleeve. The mounting member 42 is provided with a chute 41 inclined in the height direction of the sleeve 4. The sleeve 4 is used for sleeving the adjusting piece 2 and the handle 1 and can axially move relative to the handle 1. The projection 21 is placed in the chute 41. When the sleeve 4 moves towards the fixed jaw 41, the inclined groove 42 moves along with the sleeve 4, and the adjusting piece 2 is limited in the groove 14 in the axial direction, the projection 21 slides in the inclined groove 41, so that the adjusting piece 2 moves towards the bottom wall of the groove 14, and the wrench gap becomes smaller. When the sleeve 4 moves towards the sleeve hole 11, under the combined action of the protrusion 21, the inclined groove 41 and the return spring 3, the adjusting piece 2 moves towards the direction away from the bottom wall of the groove 14, and the wrench gap becomes larger.

Furthermore, the chute 41 can be arranged directly on the sleeve 4, which makes the mounting 42 unnecessary and makes the construction simpler.

The utility model discloses a spanner still includes grab handle 5 and connecting rod 6, the both ends of connecting rod 6 respectively with handle 1 and grab handle 5 swivelling joint. The grab handle 5 is provided with a groove with the shape matched with the shape of the handle 1, and the shape of one end of the grab handle 5 is matched with the shape of the trepanning 11. Referring to fig. 1, when the multipurpose handle is not used, the groove of the handle is placed against the handle, and the handle is contained in the groove of the handle, so that the structure is more compact, the space is saved, and the multipurpose handle is convenient to carry and store. Referring to fig. 2, in the working state, one end of the grip handle 5 is inserted into the trepan 11 to increase the moment and save the physical strength.

The operation of the wrench of the present invention will be described with reference to the accompanying drawings. When the adjustable jaw type screw driver works, the adjusting sleeve 4 is pushed and pulled firstly to adjust the position of the movable jaw 72, and then the caliber of a movable opening formed by the movable jaw and the fixed jaw 71 is adjusted to adapt to bolts or nuts with different specifications. The handle 5 is pulled apart, one end portion thereof is inserted into the sleeve hole 11 and clamped to form a triangular support, and the handle 5 is rotated to perform screwing operation. After the work is finished, the grip 5 is retracted and placed against the handle 1.
