Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0025] like Figure 1 and Figure 2 As shown, the universal wrench of this embodiment is used to remove fasteners, and the universal wrench includes: a main frame 10, a push rod 20 and an operating member 30. The main frame 10 has a first accommodating portion 11 for accommodating fasteners. The push rod 20 is reciprocatingly arranged in the main frame 10 along the axis of the push rod 20. The operating member 30 is rotatably arranged on the push rod 20 around the axis of the push rod 20, and when the operating member 30 rotates, it drives the push rod 20 to move in the main frame 10, so that the push rod 20 and the first accommodating portion 11 clamp the fastener at the same time or the push rod 20 is separated from the fastener. Among them, an avoidance groove 12 is provided on the inner side wall of the main frame 10 in the width direction, and the operating member 30 extends into the avoidance groove 12.

[0026] By applying the technical solution of this embodiment, a first accommodating portion 11 is provided on the main frame 10, and the first accommodating portion 11 is used to accommodate the fastener. The push rod 20 is arranged in the main frame 10 so as to be reciprocatingly movable along the axis of the push rod 20. The operating member 30 is rotatably arranged on the push rod 20 around the axis of the push rod 20, and the rotation of the operating member 30 can drive the push rod 20 to move in the main frame 10, so that the push rod 20 and the first accommodating portion 11 clamp the fastener at the same time, or the push rod 20 is separated from the fastener. Among them, an avoidance groove 12 is provided on the inner side wall of the main frame 10 in the width direction, and the operating member 30 extends into the avoidance groove 12. Through the above arrangement, when the operating member 30 rotates, it can drive the push rod 20 to move along the axis of the push rod 20, so that the push rod 20 can move toward the direction close to the first accommodating portion 11, clamping the fastener between the first accommodating portion 11 and the push rod 20, or the push rod 20 moves toward the direction away from the first accommodating portion 11, so that the push rod 20 is separated from the fastener. The operating member 30 extends into the avoidance groove 12, that is, the size of the operating member 30 is larger than the size of the inner side wall of the main frame 10, which makes it easy to rotate the operating member 30, so that it is easier to drive the push rod 20 to move. When the fastener is clamped between the push rod 20 and the first accommodating portion 11, rotating the main frame 10 can drive the fastener to rotate, and then remove the fastener. Therefore, the technical solution of this embodiment effectively solves the problem of inconvenient operation when rotating the driving member in the related art.

[0027] Specifically, the fastener may be a bolt or a nut. A universal wrench may also be used to install the fastener. It should be noted that the operating member 30 is an operating nut, and a plurality of anti-skid patterns are arranged at intervals on the outer surface of the operating nut, and the anti-skid patterns extend along the axial direction of the push rod 20, so as to facilitate the rotation of the operating nut. Of course, in other embodiments, the operating member 30 may also be a cylinder, and the anti-skid patterns are arranged at intervals on the outer surface of the cylinder.

[0028] like Figure 1As shown, in this embodiment, the main frame 10 includes a first frame 13, a second frame 14 and two reinforcements 15, the first accommodating portion 11 is arranged at the first end of the first frame 13, the first ends of the two reinforcements 15 are connected to the second end of the first frame 13, the second ends of the two reinforcements 15 are connected to the first end of the second frame 14, the spacing between the two reinforcements 15 is greater than the hole spacing of the first frame 13 and the hole spacing of the second frame 14, and the inner side walls of the two reinforcements 15 jointly form a avoidance groove 12. The reinforcement 15 not only connects the first frame 13 and the second frame 14, but also makes the connection between the first frame 13 and the second frame 14 more stable, thereby facilitating the operator to disassemble the fastener by rotating the main frame 10. The distance between the two reinforcement members 15 is greater than the hole distance of the first frame 13 and the hole distance of the second frame 14. The inner side walls of the two reinforcement members 15 together form an avoidance groove 12, and the operating member 30 extends into the avoidance groove 12, that is, the size of the operating member 30 is greater than the hole distance of the first frame 13 and the hole distance of the second frame 14. This makes it easy to drive the push rod 20 to move by rotating the operating member 30.

[0029] It should be noted that the provision of the avoidance groove 12 will reduce the strength of the main frame 10, while the provision of the reinforcement member 15 can increase the strength of the main frame 10, so that when the main frame 10 is subjected to a large force, the main frame 10 will not be damaged.

[0030] like Figure 2 As shown, the inner side walls of the first ends of the two reinforcement members 15 are connected to the outer side walls of the second ends of the first frame 13, and the inner side walls of the second ends of the two reinforcement members 15 are connected to the outer side walls of the first end of the second frame 14, and the reinforcement member 15 includes a connecting column 151. Through the above arrangement, the reinforcement member 15 can connect the first frame 13 and the second frame 14. Under the connecting action of the connecting column 151, the connection between the first frame 13 and the second frame 14 is more stable.

[0031] It should be noted that the distance between the two side walls of the avoidance groove 12 in the width direction of the main frame is the same as the distance between the two outer side walls in the width direction of the main frame 10, which facilitates the rotation of the operating member 30 and also allows a larger operating member 30 to be placed in the avoidance groove 12.

[0032] like Figure 1As shown, the universal wrench further includes a first limit plate 40 and a second limit plate 50, the first limit plate 40 is covered on the first frame 13, the second limit plate 50 is covered on the second frame 14, the first limit plate 40 and the second limit plate 50 are respectively located on both sides of the main frame 10, and the push rod 20 is located between the first limit plate 40 and the second limit plate 50. The first limit plate 40 and the second limit plate 50 can limit the push rod 20 to prevent the push rod 20 from separating from the main frame 10. The first limit plate 40 makes the overall structure of the first frame 13 more stable, and the second limit plate 50 makes the overall structure of the second frame 14 more stable, so that the universal wrench can be more stable when in use.

[0033] like Figure 1 and Figure 2 As shown, the universal wrench also includes: a third limit plate 60 and a fourth limit plate 70. The third limit plate 60 is covered on the first frame 13, and the first limit plate 40 and the third limit plate 60 are respectively located on both sides of the first frame 13. The fourth limit plate 70 is covered on the second frame 14, and the second limit plate 50 and the fourth limit plate 70 are respectively located on both sides of the second frame 14. Among them, the operating member 30 extends into the interval between the first limit plate 40 and the fourth limit plate 70 and the interval between the second limit plate 50 and the third limit plate 60. The third limit plate 60 and the fourth limit plate 70 can limit the push rod 20 to prevent the push rod 20 from separating from the main frame 10. The third limit plate 60 makes the first frame 13 more stable, and the fourth limit plate 70 makes the second frame 14 more stable, so that the universal wrench can be more stable when in use. The interval between the first limiting plate 40 and the fourth limiting plate 70 and the interval between the second limiting plate 50 and the third limiting plate 60 can limit the operating member, so that the position of the operating member is more stable during the rotation process, thereby making the movement of the push rod smoother.

[0034] like Figure 1 As shown, the second end of the second frame 14 is provided with a second accommodating portion 141, the aperture of the first accommodating portion 11 is smaller than the aperture of the second accommodating portion 141, and when the operating member 30 rotates, the push rod 20 can extend into the first accommodating portion 11 or the second accommodating portion 141. Both the first accommodating portion 11 and the second accommodating portion 141 can accommodate fasteners, and the aperture of the first accommodating portion 11 is smaller than the aperture of the second accommodating portion 141, so that the first accommodating portion 11 and the second accommodating portion 141 can accommodate fasteners of different sizes, thereby making the universality of the universal wrench better.

[0035] like Figures 1 to 3As shown, a first clamping portion 21 is provided at one end of the push rod 20 away from the second accommodating portion 141, and the first clamping portion 21 includes a first inclined surface 211 and a second inclined surface 212 connected to the first inclined surface 211, and a first preset angle is provided between the first inclined surface 211 and the second inclined surface 212, and the first accommodating portion 11 is a first fixing ring 111, and a first limiting groove 1111 is provided on the first fixing ring 111, and the fastener is clamped between the first clamping portion 21 and the first limiting groove 1111. The end of the push rod 20 away from the second accommodating portion 141 is provided with a second clamping portion 22, the second clamping portion 22 includes a third inclined surface 221 and a fourth inclined surface 222 connected to the third inclined surface 221, and a second preset angle is formed between the third inclined surface 221 and the fourth inclined surface 222. The second accommodating portion 141 is a second fixing ring 1411, and a second limiting groove 14111 is provided on the second fixing ring 1411, and the fastener is clamped between the second clamping portion 22 and the second limiting groove 14111. The first clamping portion 21 and the first limiting groove 1111 can clamp the fastener, and then when the main frame 10 is rotated, the fastener can be driven to rotate, and then the fastener can be disassembled. The second clamping portion 22 and the second limiting groove 14111 can clamp the fastener, and then when the main frame 10 is rotated, the fastener can be disassembled. The first inclined surface 211, the second inclined surface 212, and the first limiting groove 1111 make the clamping of the fastener more stable. The third inclined surface 221, the fourth inclined surface 222, and the second limiting groove 14111 make the clamping of the fastener more stable.

[0036] Preferably, the first preset angle and the second preset angle are in the range of 110° to 140°, specifically, they can be 110°, 120°, 135° or 140°, so that the contact between the first clamping portion 21 and the second clamping portion 22 and the fastener is more stable. The first limiting groove 1111 and the second limiting groove 14111 both include a plurality of grooves arranged in sequence, each of the first limiting groove 1111 and each of the second limiting grooves 14111 includes a first limiting surface and a second limiting surface, and there is a fourth preset angle between the first limiting surface and the second limiting surface, and the fourth preset angle is in the range of 110° to 140°, specifically, it can be 110°, 115°, 120°, 135° or 140°. The partial structure of the fastener is located between the first limiting surface and the second limiting surface.

[0037] It should be noted that the push rod 20 is also provided with a push rod that can be moved along the axis of the push rod 20, and the push rod can be extended into the first accommodating portion 11. The end of the push rod away from the second accommodating portion 141 is provided with a third clamping portion, and the third clamping portion includes a fifth inclined surface and a sixth inclined surface connected to the fifth inclined surface. There is a third preset angle between the fifth inclined surface and the sixth inclined surface, and the third preset angle is greater than the first preset angle, so that the push rod can adapt to more different types of fasteners, making the universal wrench more versatile. The maximum value of the third preset angle is 150°, which can be 125°, 130°, 145° or 150°. A driving gear is provided on the push rod 20, and a driven rack is provided on the push rod. The rotation of the driving gear can drive the driving rack to rotate, and then the push rod can be extended into the first accommodating portion 11 or retracted into the push rod 20.

[0038] like Figure 1 and Figure 2 As shown, the first frame 13 includes a connecting frame 131 and an adjusting frame 132 connected to the connecting frame 131, the connecting frame 131 is connected to the second frame 14 through a reinforcing member 15, the adjusting frame 132 is movably arranged on the connecting frame 131 along the axial direction of the abutting rod 20, and the first receiving portion 11 is arranged at one end of the adjusting frame 132 away from the connecting frame 131. By moving the adjusting frame 132, the distance between the adjusting frame 132 and the second receiving portion 141 can be increased or decreased. When the distance between the adjusting frame 132 and the second receiving portion 141 increases, when the operator provides the same force, the universal wrench can apply a larger torque to the fastener, so as to facilitate the removal of the fastener.

[0039] It should be noted that when the torque required to remove the fastener is large, it can also be achieved by increasing the distance between the adjustment frame 132 and the second accommodating portion 141, thereby increasing the force arm of the force applied when removing the fastener, thereby enabling the operator to remove the fastener more effortlessly. The connecting frame 131 includes a first connecting rod and a second connecting rod, a first avoidance gap is provided on the first fixing ring 111, the first fixing ring 111 is connected between the first connecting rod and the second connecting rod, the first connecting rod is connected to the first end of the first avoidance gap, and the second connecting rod is connected to the second end of the first avoidance gap.

The hole pitch of the first frame 13 refers to the distance between the first connecting rod and the second connecting rod, and the hole pitch of the second frame 14 refers to the distance between the third connecting rod and the fourth connecting rod. The inner side wall of the main frame 10 in its width direction refers to the side wall surrounded by the surface of the first connecting rod facing the second connecting rod, the surface of the second connecting rod facing the first connecting rod, the surface of the third connecting rod facing the fourth connecting rod, and the surface of the fourth connecting rod facing the third connecting rod.

When the adjustment frame 132 is in the extended position, the locking rod 81 is inserted into the first locking hole 82 and a second locking hole 83 aligned with the first locking hole 82. After the adjustment frame 132 is adjusted from the initial position to the extended position, the adjustment frame 132 and the connecting frame 131 can be fixed by the locking rod 81, the first locking hole 82, and the second locking hole 83, so as to facilitate the use of the universal wrench.

[0041] It should be noted that, in this embodiment, when the adjustment frame 132 is in the initial position, the locking rod 81 is inserted into one of the plurality of second locking holes 83 closest to the second receiving portion 141. When the fastener is removed through the second receiving portion 141, the setting of the adjustment frame 132 is convenient for the operator to hold, and then it is convenient for the operator to rotate the main frame body to remove the fastener.

The fifth connecting rod and the sixth connecting rod are both located outside the connection frame 131.

[0043] like Figure 1 As shown, the universal wrench further includes a threaded structure, which is disposed between the operating member 30 and the push rod 20. The threaded structure enables the operating member 30 to more easily drive the push rod 20 to move.

[0044] It should be noted that the push rod includes a first side wall, a second side wall, a third side wall and a fourth side wall which are arranged in sequence, the fourth side wall is connected to the third side wall, the second side wall and the fourth side wall are arc-shaped surfaces, the axes of the second side wall and the fourth side wall coincide, and the radii are equal. The thread structure includes an external thread and an internal thread. The external thread part is arranged on the second side wall, and the other part is arranged on the fourth side wall. The internal thread is arranged in the mounting hole of the operating member 30.

[0045] In this embodiment, when the universal wrench is in use, the operating member 30 is rotated so that the push rod 20 extends into the first accommodating portion 11 or the second accommodating portion 141, and then the fastener is clamped between the first accommodating portion 11 and the push rod 20 or between the second accommodating portion 141 and the push rod 20, and the main frame 10 is rotated to drive the fastener to rotate and remove the fastener.

[0046] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".
