The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1 to 4, the embodiment of the present invention discloses a star wrench convenient to use, including a wrench body 100, wherein the wrench body 100 is L-shaped, and includes a first driver section 110 and a second driver section 120, the length of the first driver section 110 is greater than that of the second driver section 120, a first driver head 111 is disposed at an end of the first driver section 110, a second driver head 121 is disposed at an end of the second driver section 120, and a spherical driver head 130 is disposed at an end of the first driver head 111, so that the wrench body 100 can be inserted into a screw hole of a screw in an inclined manner.
The wrench body 100 of the wrench is provided with the first screwdriver head 111 and the second screwdriver head 121, different screwdriver heads can be selected according to use environments, different from the prior art, the end part of the first screwdriver head 111 of the wrench is provided with the spherical screwdriver head 130, the spherical screwdriver head 130 can incline relative to a screw after being inserted into the screw hole of the screw due to the shape of the spherical screwdriver head 130, therefore, when the screw needing to be screwed or unscrewed is positioned below an obstacle and the screwdriver head is difficult to insert into the screw hole, the wrench can be obliquely inserted (refer to fig. 2) aiming at the screw hole, the use is convenient, and the problem that the screw at a special position is difficult to operate is solved.
Specifically, the spherical screwdriver head 130 includes a sphere 131 and a screwdriver stripe 132 disposed outside the sphere 131, the screwdriver stripe 132 extends from the end of the sphere 131 to the first screwdriver head 111, the spherical screwdriver head 130 is similar to a common screwdriver head, the outer surface is provided with screwdriver stripes matched with the screw hole, the screwdriver stripe 132 on the spherical screwdriver head 130 is arc-shaped, when the axial direction of the spherical screwdriver head 130 changes the angle, so that when the spherical screwdriver head 130 is in the screw hole, adjusting the angle of the wrench body 100 will not cause the spherical screwdriver head 130 to disengage from the screw.
Referring to fig. 3, when screwing or unscrewing the screw without being blocked by an obstacle, the spherical driver head 130 may be directly inserted into the screw hole, and if the screw hole is deep, the first driver head 111 may be inserted into the screw hole together with the spherical driver head 130, so that the diameter of the spherical driver head 130 is the same as that of the first driver head 111, and if the diameter of the spherical driver head 130 is smaller than that of the first driver head 111, the inserted spherical driver head 130 may not play a role in rotating the screw.
After the spanner is obliquely inserted into the screw hole, the inclination angle of the spanner needs to be adjusted, so that the spherical screwdriver head 130 can be better matched with the screw hole, in the process, if the first screwdriver head 111 is abutted against the screw, the adjustment of the spherical screwdriver head 130 can be affected, in order to reduce the influence of the first screwdriver head 111 on the spherical screwdriver head 130, the spherical screwdriver head 130 is connected with the first screwdriver head 111 through the connecting section 140, the diameter of the connecting section 140 is smaller than the diameters of the spherical screwdriver head 130 and the first screwdriver head 111, so that the connecting section 140 can be used for connecting the spherical screwdriver head 130 and the first screwdriver head 111, and meanwhile, the influence of the abutment of the first screwdriver head 111 and the screw on the angle adjustment when the angle of the spanner body 100 is adjusted after the spherical screwdriver head 130 is inserted into the screw hole can be avoided, so as to facilitate the use of a user.
After the relative position between the spherical screwdriver head 130 and the screw hole is adjusted, the wrench body 100 needs to be rotated to drive the spherical screwdriver head 130 to rotate the screw, in this process, the wrench body 100 is kept in an inclined state, so that the wrench body 100 is not fixed in position, and is easily shifted in rotation, and is inconvenient to use, and in general, a star wrench is convenient to rotate, and the first driver segment 110 and the second driver segment 120 of the wrench body 100 are mostly cylinders with polygonal cross sections, in the present invention, the first driver segment 110 is a cylinder, so that the wrench body 100 can support the wrench body 100 by leaning on or padding an object on the obstacle, so as to keep the stability of the wrench body 100 in the rotation process, and not easy to deviate, and the friction between the cylindrical first driver segment 110 and the object to be depended on is small, thereby facilitating the use of the user.
Referring to fig. 5 to 7, different from the above embodiments, in another embodiment of the present invention, the spherical screwdriver head 130 is oblate, and the radius of the oblate pole axis direction is smaller than that of the equatorial direction, so that when facing screw holes with different specifications, the included angle between the equatorial direction of the spherical screwdriver head 130 and the axial direction of the screw hole can be adjusted by adjusting the included angle between the wrench body 100 and the screw, so that the spherical screwdriver head 130 can be matched with the screw hole. In fig. 6 and 7, both are schematic diagrams of the fitting between the oblate spherical screwdriver head 130 and the screw, the inner diameter of the screw hole in fig. 6 is smaller than that in fig. 7, the spherical screwdriver heads 130 with two different inner diameters can be fitted with the screw hole only by adjusting the angle, and the application range is wider.
While the utility model has been described with reference to specific embodiments thereof, it will be understood by those skilled in the art that the utility model is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the utility model as set forth in the following claims. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
