[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0013] like Figures 1-4 As shown, a multi-functional wrench includes a wrench head 1, which is elliptical cylindrical in shape. A handle 6 is fixedly connected to the top surface of the wrench head 1. A horizontal mounting groove 2 is formed inside the wrench head 1. A mounting groove 3 9 is horizontally connected to one side of the mounting groove 2. The outer end of the mounting groove 3 9 penetrates one side wall of the wrench head 1. The mounting groove 2 and the mounting groove 3 9 together form a horizontal groove. A mounting groove 2 3 is formed at the bottom of the wrench head 1, which is connected to the mounting groove 2. Two sliders 4 are provided in the mounting groove 2. Both sliders 4 are rectangular. The two sliders 4 have three... The sidewalls of both sliders 4 are in contact with the sidewalls of the mounting slot 2. The two sliders 4 are driven by the driving component to move in a relative or opposite direction. The bottom of each slider 4 is fixedly connected with a clamping rod 5. The clamping rod 5 passes through the mounting slot 3 and extends downwards out of the wrench head 1. The clamping rod 5 is a square column. The three sidewalls of the two clamping rods 5 located in the mounting slot 3, except for the opposite sidewalls, are in contact with the sidewalls of the mounting slot 3. The two clamping rods 5 together form a jaw. When the two clamping rods 5 are close to each other, the jaws are in a clamped state. When the two clamping rods 5 are far apart, the jaws are in an open state.

[0014] The driving component includes a screw 7, a rotating rod 10, a first gear 11, and a second gear 12. The screw 7 is rotatably connected in the first mounting groove 2 and threadedly connected to two sliders 4. The second gear 12 is mounted on the screw 7 between the two sliders 4. The rotating rod 10 is rotatably connected in the third mounting groove 9. The central axis of the rotating rod 10 is parallel to that of the screw 7. The central axis of the screw 7 coincides with the major axis of the elliptical cylindrical wrench head 1. The first gear 11, which meshes with the second gear 12, is fixedly connected to the rotating rod 10.

[0015] The threads at both ends of the screw 7 are in opposite directions, and one end of the screw 7 moves through the mounting groove 2 and is connected to a rotating plate 8.

[0016] The two clamping rods 5 have a strip-shaped groove 13 extending from bottom to top along the length direction on their opposite sidewalls, and the lower end of the strip-shaped groove 13 passes through the bottom of the clamping rod 5.

[0017] Multiple strip-shaped grooves 14 are equidistantly provided along the length direction on the opposite sidewalls of the two clamping rods 5.

[0018] The upper end of the grip 6 has a through hole 15, and a round rod 16 is slidably disposed in the through hole 15. A stop block 17 is fixedly connected to any end of the round rod 16.

[0019] The outer diameter of the mounting groove 39 is 2.5-4cm, and the distance between the side of the gear 11 near the outer end of the mounting groove 39 and the outer end of the mounting groove 39 is less than 1cm.

[0020] The horizontal length of mounting groove 2 is at least twice the horizontal length of mounting groove 9. Figure 1 For example, the major axis of the elliptical cylindrical wrench 1 is the distance between its left and right ends, the minor axis of the elliptical cylindrical wrench 1 is the distance between its front and rear ends, and the length of the left and right ends of the mounting groove 1 2 is at least twice the length of the left and right ends of the mounting groove 3 9.

[0021] When clamping is required using this utility model, two driving methods can be used to suit different usage scenarios; simultaneously, two different clamping methods can be selected to suit the disassembly and assembly of different parts. In the first driving method, when using this utility model to disassemble or assemble parts such as nuts, the two clamping rods 5 on the jaws are placed on both sides of the nut. Then, by rotating the rotating plate 8, the rotating plate 8 drives the screw 7 to rotate synchronously, causing the two sliders 4 to move closer together, and the two sliders 4 drive the two clamping rods 5 to move closer together. In the second driving method, a finger can be inserted into the opening of the mounting groove 3 to actuate gear 11. Gear 11 drives gear 2 12 to rotate, causing gear 2 12 to rotate the screw 7, thereby causing the screw 7 to move the two sliders 4 closer together, and the two sliders 4 drive the two clamping rods 5 closer together. Through these two driving methods, the two clamping rods 5 are brought closer together, thus... The jaws are in a clamped state, and during the clamping process, the two clamping rods 5 can contact the two side walls of the nut to clamp it, or the strip grooves 13 on the opposite side walls of the two clamping rods 5 can correspond to the edges on both sides of the nut, thus clamping it when the two clamping rods 5 come close to each other. The above is one clamping method for the outer wall of the nut, nut, bolt and other parts that need to be disassembled. This utility model, through two different driving methods, makes it applicable to the disassembly and assembly of nuts, nuts, bolts and other parts in open environments or in countersunk holes. Since the strip grooves 13 on the opposite side walls of the two clamping rods 5 can achieve a stable and reliable clamping of the edges on both sides of the nut, it effectively prevents slippage during operation. Therefore, using this utility model to disassemble and assemble nuts, nuts, bolts and other parts is convenient, quick and easy to operate.

[0022] When disassembling or assembling components such as sleeves with internal threads that have openings at the top and bottom, the above two driving methods can also be used: rotating the rotating plate 8 in the opposite direction, or turning the gear 11 in the opposite direction to drive the screw 7 to rotate in the opposite direction, so that the two sliders 4 move away from each other, making the jaws open, and the opposite sidewalls of the two sliders 4 are tightly supported on both sides of the internal thread. Under the action of the second groove 14, a stable force point is obtained, thereby pressing the inner wall of the internal thread component. This is the second clamping method of this utility model.

[0023] After completing the two different clamping operations, the operator only needs to hold the handle 6 of the wrench and rotate it to carry out the disassembly and assembly work. The round rod 16 set on the handle 6 can increase the torque when rotating the handle 6 in an open environment.

[0024] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
