A multi-functional wrench

Abstract

This utility model discloses a multi-functional wrench, including a handle, a sloping end, a threaded seat, a push rod, a threaded post, a locking block, and a combined structure. By pulling the rotating block to the right, the wrench can be moved out, allowing the nut and the opening of the wrench to be aligned. Rotating the handle then drives the wrench to tighten the nut, thus fixing the wrench to the handle in a combined manner. This avoids the inconvenience of frequent tool changes. When disassembling the wrench, the wrench is pulled through the groove, causing the inner side of the wrench's mounting opening to slide out, completing the disassembly. Different sizes of wrenches can then be replaced to accommodate nuts of different sizes. The locking head rotates into the connecting plate and is limited by an elastic locking element, providing better fixation and greater stability during use.

Detailed Implementation

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 and Figure 2This utility model provides a multifunctional wrench, including a handle 1, an integrally formed sloping end 2, an integrally formed threaded seat 3 in the handle 1, a push rod 4 slidably connected in the handle 1, a threaded post 5 rotatably connected to the push rod 4, the threaded post 5 being threadedly connected to the threaded seat 3, a locking block 6 fixed at the end of the push rod 4, and a combination structure 7 provided on the handle 1.

[0021] Specifically, when using it, the saka-guchi 2 is clamped onto the bolt, and then the threaded post 5 is rotated. Since the threaded post 5 is threadedly connected to the threaded seat 3, when the threaded post 5 rotates, it can drive the push rod 4 to slide, and then push the clamping block 6 against the bolt surface. Then, the handle 1 is rotated to tighten the bolt.

[0022] Please see Figure 3 and Figure 4 This utility model provides a multi-functional wrench. The combined structure 7 includes a fixing groove 71. The other end of the handle 1 is provided with a fixing groove 71. A rotating block 701 is assembled in the fixing groove 71. A connecting rod 72 is integrally formed on the surface of the rotating block 701. The connecting rod 72 can be connected to the handle 1. A first magnetic block 73 is provided inside the handle 1. The connecting rod 72 can be magnetically connected to the first magnetic block 73 to fix the rotating block 701 in the fixing groove 71. A Phillips head tube 74 is provided inside the rotating block 701. A connecting rod 75 is integrally formed on the surface of the rotating block 701. A positioning structure 76 is provided on the connecting rod 75. An anti-slip groove 717 is provided on the rotating block 701 to provide an anti-slip effect when moving the rotating block 701.

[0023] Specifically, by pulling the rotating block 701 to the right, the connecting rod 72 is separated from the first magnetic block 73, and the rotating block 701 can be moved out. Then, the plum blossom tube 74 can be connected with the nut. Then, by turning the handle 1, the plum blossom tube 74 can be driven to tighten the nut. The plum blossom tube 74 is fixed on the handle 1 in a combined manner, which avoids the trouble of frequently changing tools.

[0024] Please see Figure 3 The rotating block 701 has an installation port 77, a limit groove 78 is provided in the installation port 77, a limit plate 79 is integrally formed on the surface of the rotating block 701, a second magnetic block 710 is provided in the installation port 77, the plum blossom tube 74 can be magnetically connected with the second magnetic block 710, the plum blossom tube 74 is installed in the installation port 77, and a groove 716 is provided on the plum blossom tube 74 to facilitate the movement of the plum blossom tube 74.

[0025] Specifically, when it is necessary to disassemble the Phillips head 74, the Phillips head 74 is pulled by the groove 716, causing the inner side of the mounting port 77 of the Phillips head 74 to slide out of the mounting port 77, thus completing the disassembly of the Phillips head 74. Then, Phillips head 74 of different sizes can be replaced to allow for replacement with nuts of different sizes, avoiding the need to carry wrenches of different sizes, and making replacement convenient. When the Phillips head 74 is installed into the mounting port 77, the limiting plate 79 will move into the limiting groove 78 to prevent the Phillips head 74 from rotating in the mounting port 77.

[0026] The rotating block 701 has a connecting plate 711 integrally formed on its surface. The handle 1 has a rotating component 712 rotatably connected inside by a torsion spring. The rotating component 712 has a locking head 713 integrally formed on it. The locking head 713 can be locked in the connecting plate 711. The connecting plate 711 is provided with an elastic locking component 714. The handle 1 is provided with a stop block 715, which limits the rotation component 712.

[0027] Specifically, when the rotating block 701 is retracted into the fixed groove 71, the connecting plate 711 is inserted into the handle 1, and then the rotating component 712 is rotated so that the clamping head 713 is rotated into the connecting plate 711, thereby positioning the rotating block 701. This prevents the rotating block 701 from rotating when the wrench is used. After the clamping head 713 is rotated into the connecting plate 711, it is limited by the elastic clamping component 714, which has a better fixing effect.

[0028] Please see Figure 4 The positioning structure 76 includes a sliding frame 761, which is slidably connected to the handle 1. The connecting rod 75 is rotatably connected to the sliding frame 761. An elastic fixing member 762 is provided in the sliding frame 761. A limiting head 763 is provided on the surface of the elastic fixing member 762. A locking tooth 764 is provided on the connecting rod 75. The limiting head 763 is locked in the locking pool 764.

[0029] Specifically, when the rotating block 701 is rotated, the connecting rod 75 will be driven to rotate. Since the locking tooth 764 is fixed on the connecting rod 75, the rotating rod 75 will also drive the locking tooth 764 to rotate. The limiting head 763 is locked on the locking tooth 764 through the elastic fixing member 762. Therefore, positioning can be performed after the rotating block 701 rotates, so as to achieve stepless positioning after the rotating block 701, avoiding the problem that the tube will rotate and become inconvenient to use when using the tube.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
