Description

Technical Field

[0001] The utility model relates to the field of hand tools, and more specifically, to a novel plum wrench. Background Art

[0002] At present, when people tighten or remove screws and nuts on workpieces, they often need to use a plum wrench. When in use, the plum wrench is set on the screw or nut and twisted to tighten or remove the screw or nut. It is simple and convenient. Therefore, the plum wrench has been widely used at present.

[0003] However, during use, people find that when screws and nuts need to be tightened or removed, if the length of the spanner is short, it is often difficult to tighten or remove the screws and nuts. Therefore, an extended handle is generally added to the back of the spanner. However, the spanner and the extended handle are fixedly connected to each other in the current market, so the spanner is relatively long as a whole, which is inconvenient to carry. At the same time, a spanner of one specification can only correspond to an extended handle of one length, so maintenance personnel need to carry a plurality of spanners of different specifications when going out.

[0004] Therefore, it is necessary to propose a novel box spanner that solves the above problems. Utility Model Content

[0005] The utility model provides a novel plum wrench to overcome at least one defect (deficiency) of the prior art.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows: a new type of plum wrench, including an extended handle and a plum wrench body for tightening screws or nuts;

[0007] The plum wrench body is provided with a quick-release head, and the end of the extended handle is provided with a clamping limit block matched with the quick-release head;

[0008] The box spanner body is detachably arranged on the clamping limit block of the extended handle through the quick-release head. Through the arrangement of the quick-release head and the clamping limit block, the box spanner body and the extended handle can be quickly connected, so that it has a force-adding effect when tightening or removing screws and nuts, which is convenient for removing or tightening screws and nuts. Since the extended handle and the box spanner body are detachable, box spanner bodies of different sizes and extended handles of different lengths can be matched and used according to needs during use, which is also convenient to carry and saves the space required for carrying.

[0009] Furthermore, the quick-release head includes a quick-release mounting seat, a limiting top block, a spring and a limiting top screw;

[0010] The quick-release mounting seat is arranged on the plum wrench body, and a connecting hole is arranged on the quick-release mounting seat;

[0011] A limit stopper is provided on the top of the communicating hole;

[0012] The limit top screw is arranged at the bottom of the communicating hole with adjustable height, and the limit top block and the spring are sequentially sleeved in the communicating hole from top to bottom;

[0013] The limit top block is provided with a limit protrusion matching the limit stop block, one end of the spring is connected to the limit top screw, and the other end is connected to the limit top block. Under the elastic force of the spring, the end of the limit top block extends out of the connecting hole and is connected to the card-set limit block. The spring can be limited by the limit top screw provided at the bottom of the connecting hole. Under the action of the spring, the limit top block extends out of the connecting hole and is connected to the card-set limit block, thereby realizing rapid clamping between the quick-release head and the card-set limit block.

[0014] Furthermore, an internal thread is provided at the bottom of the connecting hole, and an external thread is provided on the outer side of the limiting top screw. The limiting top screw can be tightened in the internal thread of the connecting hole through the external thread.

[0017] The clamping mounting seat is connected to the end of the extended handle, and the inner concave position is arranged on the clamping mounting seat;

[0018] The locking limit hole is arranged at the center position of the inner concave position. When the extended handle and the plum blossom wrench body are locked with each other, the end of the limiting top block extends out of the connecting hole under the action of the spring and is locked on the locking limit hole. By setting the inner concave position on the locking mounting seat and arranging the locking limit hole on the inner concave position, when the quick-release head and the locking limit block are locked with each other, the end of the limiting top block extends out of the connecting hole under the action of the spring and is locked on the locking limit hole, thereby realizing a quick connection between the locking limit block and the quick-release head.

[0019] Furthermore, the end of the extended handle is arranged on the clamping mounting seat below the inner recess. When the extended handle and the plum blossom wrench body are clamped with each other, the extended handle and the plum blossom wrench body abut against each other. Since the end of the extended handle is arranged on the clamping mounting seat below the inner recess, the insertion and installation of the plum blossom wrench body can be limited, which facilitates the connection and installation between the extended handle and the plum blossom wrench body.

[0020] Furthermore, the plum blossom spanner body comprises a plum blossom spanner connecting portion, a plum blossom spanner reinforcing sleeve block and a plum blossom spanner head for tightening screws or nuts;

[0021] The plum blossom spanner head is connected to the plum blossom spanner connecting part, and the plum blossom spanner reinforcing sleeve block is sleeved at the intersection between the plum blossom spanner head and the plum blossom spanner connecting part. The plum blossom spanner head can be used to tighten or remove screws and nuts, and the plum blossom spanner connecting part can be connected to the extended handle, and the plum blossom spanner reinforcing sleeve block can strengthen the connection strength between the plum blossom spanner connecting part and the plum blossom spanner head.

[0022] Furthermore, the plum blossom wrench head, the plum blossom wrench reinforcement sleeve and the plum blossom wrench connecting part are an integrated structure, and the integrated structure of the plum blossom wrench head, the plum blossom wrench reinforcement sleeve and the plum blossom wrench connecting part can effectively simplify the structure of the plum blossom wrench body.

[0023] Furthermore, the connecting part and the extended handle of the plum blossom wrench are both hollow structures. Under the condition of equal weight, the outer diameters of the connecting part and the extended handle of the plum blossom wrench can be increased to enhance the bending moment resistance of the connecting part and the extended handle of the plum blossom wrench.

[0024] Furthermore, the extended handle is provided with anti-slip patterns, and the provision of the anti-slip patterns can enhance the friction between the maintenance personnel's hand and the extended handle when twisting the extended handle, thereby avoiding slipping when twisting.

[0025] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0026] The new type of spanner disclosed by the utility model can realize quick connection between the spanner body and the extended handle through the arrangement of the quick-disassembly head and the clamping limit block, so that the spanner body can have a force-adding effect when tightening or removing screws and nuts, and it is convenient to remove or tighten the screws and nuts. Since the extended handle and the spanner body are detachable, the spanner bodies of different sizes and the extended handles of different lengths can be matched and used according to needs during use, and it is also convenient to carry and saves the space required for carrying.
