Description

Technical Field

[0001] The utility model relates to the field of wrenches, and more specifically to a multifunctional socket wrench. Background Art

[0002] Socket wrenches are generally called sockets. They are composed of multiple sockets with hexagonal or twelve-angle holes and are equipped with a variety of accessories such as handles and connecting rods. They are particularly suitable for turning bolts or nuts in very narrow or deep recesses.

[0003] However, in the prior art, since the grip structure of the sleeve handle is relatively simple, when a very tight bolt is to be unscrewed, the torque is short and the user cannot exert force effectively, resulting in great effort in unscrewing the tight bolt, which has limitations in use.

[0004] Therefore, a multifunctional socket wrench is proposed to address the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multifunctional socket wrench to solve the problems raised in the above background technology.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A multifunctional socket wrench comprises a handle, a positioning pin is fixedly connected to the bottom of the handle, the outer wall of the positioning pin is rotatably connected to a No. 1 turning handle and a No. 2 turning handle, the No. 1 turning handle is located inside the No. 2 turning handle, a No. 1 limiting groove is provided on one side of the No. 1 turning handle, a No. 2 spring is fixedly connected to the inside of the top end of the handle, a No. 2 limiting block is fixedly connected to the top end of the No. 2 spring, the diameter of the No. 2 limiting block is smaller than the diameter of the No. 1 limiting groove, and the No. 2 limiting block is clamped inside the No. 1 limiting groove.

[0010] Furthermore, a No. 2 limit groove is opened on one side of the No. 2 turning handle, a No. 1 spring is fixedly connected to the inside of the No. 1 turning handle, one end of the No. 1 spring is fixedly connected to a No. 1 limit block, the diameter of the No. 1 limit block is smaller than the diameter of the No. 2 limit groove, and the No. 1 limit block is clamped in the inside of the No. 2 limit groove.

[0011] Furthermore, a fixing block is fixedly connected to the lower end of the handle, and a sleeve rod is fixedly connected to one end of the fixing block.

[0012] Furthermore, a sleeve is slidably connected inside the sleeve rod.

[0013] Furthermore, a mounting block is fixedly connected to the outer wall of the sleeve, an anti-slip pad is fixedly connected to the inside of the mounting block, and four sleeves of different specifications are slidably connected to the mounting block.

[0014] Furthermore, the exteriors of the four sleeves of different specifications are fitted with the anti-slip pad.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] In this solution, the user turns both the No. 1 and No. 2 handlebars until they are perpendicular to the handlebars, and then holds the No. 1 and No. 2 handlebars at the same time to drive the handlebars to rotate. Through this design, if the bolts need to be tightened very tightly or the tightened bolts need to be unscrewed, the No. 1 and No. 2 handlebars can be turned to increase the torque, thereby saving effort in the process of turning the bolts.

[0027] Example:

[0028] See also Figure 1-4 A multifunctional socket wrench comprises a handle 1, a positioning pin 24 is fixedly connected to the lower part of the handle 1, the outer wall of the positioning pin 24 is rotatably connected to a No. 1 turning handle 16 and a No. 2 turning handle 2, the No. 1 turning handle 16 is located inside the No. 2 turning handle 2, a No. 1 limiting groove 19 is provided on one side of the No. 1 turning handle 16, a No. 2 spring 22 is fixedly connected to the inner part of the top of the handle 1, a No. 2 limiting block 23 is fixedly connected to the top of the No. 2 spring 22, the diameter of the No. 2 limiting block 23 is smaller than the diameter of the No. 1 limiting groove 19, the No. 2 limiting block 23 is clamped in the No. 1 limiting groove 19, in this solution, if the user needs When the bolt to be removed is relatively tight and needs to increase the lever arm, the user can rotate the No. 1 turning handle 16 and rotate the No. 1 turning handle 16 to be perpendicular to the handle 1. During the rotation of the No. 1 turning handle 16, the inner wall of the No. 1 limiting groove 19 will squeeze the No. 2 limiting block 23 above the handle 1. Since the No. 2 limiting block 23 is an arc-shaped structure, the No. 2 limiting block 23 will slide along the inside of the handle 1 after being squeezed. Then, one hand presses the top of the handle 1 and the other hand moves the No. 1 turning handle 16. The lever arm can be increased by rotating the No. 1 turning handle 16 to help the user rotate the relatively tight bolt.

[0029] See also Figure 1-4The first spring 17 is also elastically deformed and contracted, and after the second turning handle 2 is rotated to be perpendicular to the handle 1, the first turning handle 16 is rotated again to rotate the first turning handle 16 to be perpendicular to the handle 1, and then the user can rotate the first turning handle 16 and the second turning handle 2 at the same time to unscrew or tighten the bolt.

[0030] See also Figure 1-4 The lower end of the handle 1 is fixedly connected with a fixing block 11, and one end of the fixing block 11 is fixedly connected with a sleeve rod 12. In this solution, the fixing block 11 plays a connecting role between the handle 1 and the sleeve rod 12.

[0031] See also Figure 1-4 A sleeve 15 is slidably connected inside the sleeve rod 12. In this solution, the sleeve 15 is used to remove or tighten the bolt.

[0032] See also Figure 1-4 The outer wall of the sleeve 15 is fixedly connected to the mounting block 13, and the interior of the mounting block 13 is fixedly connected to the anti-skid pad 14. Four sleeves 15 of different specifications are slidably connected to the mounting block 13. In this solution, the mounting block 13 is used to store sleeves 15 of different specifications. The anti-skid pad 14 protects the sleeves 15 of different specifications and the interior of the mounting block 13, and at the same time, the sleeve 15 is subjected to a certain extrusion pressure when placed inside the mounting block 13, so that the sleeve 15 is placed more firmly in the mounting block 13.

[0033] See also Figure 1-4 The outsides of four sleeves 15 of different specifications are fitted with the anti-skid pad 14 . In this solution, the anti-skid pad 14 can increase the friction between the sleeve 15 and the mounting block 13 .

[0034] Working principle: If the bolt that the user needs to remove is relatively tight and needs to increase the lever arm, the user can rotate the No. 1 turning handle 16 and turn the No. 1 turning handle 16 to be perpendicular to the handle 1. During the rotation of the No. 1 turning handle 16, the inner wall of the No. 1 limiting groove 19 will squeeze the No. 2 limiting block 23 above the handle 1. Because the No. 2 limiting block 23 is an arc structure, when the No. 2 limiting block 23 is squeezed, it will slide along the inside of the handle 1. Then, one hand presses the top of the handle 1 and the other hand turns the No. 1 turning handle 16. The lever arm can be increased by rotating the No. 1 turning handle 16 to help the user turn the handle 1 more tightly. If the user needs to continue to increase the force arm to turn the tightened bolt, the user can first turn the No. 2 turning handle 2. During the rotation of the No. 2 turning handle 2, the inner wall of the No. 2 limit groove 21 will squeeze the No. 1 limit block 18. After being squeezed, the No. 1 limit block 18 will move along the direction inside the No. 1 turning handle 16, and the No. 1 spring 17 will also undergo elastic deformation and contraction. After the No. 2 turning handle 2 is rotated to be perpendicular to the handle 1, the No. 1 turning handle 16 is rotated to be perpendicular to the handle 1. Then the user can simultaneously rotate the No. 1 turning handle 16 and the No. 2 turning handle 2 to unscrew or tighten the bolt.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
