Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical maintenance tools, and in particular relates to an extended force rod for a wrench. Background Art

[0002] A wrench is a commonly used mechanical maintenance tool, usually used for tightening and removing bolts. However, for extremely strong bolts, or when the bolts need to be tightened very firmly, it is difficult to rely on a wrench. Therefore, a wrench extension rod is needed to save effort when tightening and removing the bolts.

[0003] In the Chinese patent with publication number CN203495843U, a force rod for an open-end wrench is mentioned, including a force rod body, a notch is set at the front end of the force rod, a fulcrum groove is set under the bottom surface of the end of the force rod in front of the notch, and a step is provided on the force rod behind the notch to form a force groove, the working surface of the open-end wrench contacts the top surface of the force groove, the open-end wrench is located in the notch, and the handle of the open-end wrench is stuck in the fulcrum groove. The structure of the utility model is adopted to extend the torque of the open-end wrench, and the screw can be easily removed by grasping the handle at the end of the force rod.

[0004] However, the above device relies on the force groove to fix the wrench, and the fixed wrench is still easy to loosen, resulting in the wrench easily falling off from one side of the force rod during subsequent tightening and removal of the bolts.

[0005] Therefore, those skilled in the art have proposed a wrench extension force rod to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a wrench extension force rod to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Wrench extension rod, including:

[0009] Grip mechanism;

[0010] A connecting and fixing mechanism, one end of which is fixedly mounted on one end of the holding mechanism;

[0011] The wrench, the connecting and fixing mechanism comprises a U-shaped hook 1 and a U-shaped hook 2, and the connecting and fixing mechanism clamps and fixes the wrench through the U-shaped hook 1 and the U-shaped hook 2.

[0012] Preferably, the holding mechanism comprises an arc-shaped handle, and a circular hole is formed on a surface of one end of the arc-shaped handle away from the connecting and fixing mechanism.

[0013] Preferably, the connecting and fixing mechanism also includes a connecting handle, one end of the connecting handle is fixedly installed on one end of the arc-shaped gripping handle, the other end of the connecting handle is fixedly installed with a bending handle, one end of the bending handle is fixedly installed with a fixing handle, the fixing handle and the connecting handle are parallel to each other, the U-shaped hook 1 is fixedly installed on one end of the fixing handle, and the U-shaped hook 2 is fixedly installed on the outer side of the outer wall of one side of the bending handle close to the outer side of the U-shaped hook 1.

[0014] Preferably, a threaded hole is formed on an outer wall of one side of the U-shaped hook 2, a stainless steel screw is screwed inside the threaded hole, and one end of the stainless steel screw is against an outer wall of one side of the wrench.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The utility model is provided with a connecting and fixing mechanism, which clamps and fixes the end of the wrench at two positions by U-shaped hook 1 and U-shaped hook 2, and then presses one end of the wrench by a stainless steel screw to fix the wrench. The wrench is lengthened by the connecting handle and the arc-shaped grip handle, so that it is convenient to apply force to the wrench at the first time of tightening and disassembly, thereby making the bolt fixation more secure, or loosening a secure bolt. Conventional bolt tightening and disassembly can be performed by an ordinary wrench. At the last time of tightening and the first time of disassembly, force can be applied by the device, and the wrench handle is clamped in the form of double hooks, so that the wrench is not easy to loosen.

[0017] (2) The utility model is provided with an arc-shaped handle and a connecting and fixing mechanism, which is suitable for auxiliary force application of a three-way spanner, an adjustable spanner, a ratchet spanner, etc., to help tighten and loosen bolts, and to perform operations in spaces that are out of reach of manual labor and inconvenient to apply force. The connecting handle, the curved handle and the fixed handle are quenched and have good fatigue resistance and toughness. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 As shown, the wrench extension rod includes:

[0027] Holding mechanism 1;

[0028] A connecting and fixing mechanism 2, one end of which is fixedly mounted on one end of the holding mechanism 1;

[0029] The wrench 3, the connecting and fixing mechanism 2 includes a U-shaped hook 1 204 and a U-shaped hook 206, and the connecting and fixing mechanism 2 clamps and fixes the wrench 3 through the U-shaped hook 1 204 and the U-shaped hook 206.

[0030] As can be seen from the above, when in use, the user holds the device through the gripping mechanism 1, aligns one end of the wrench 3 with the bolt, and can use the device to tighten or remove the bolt. When the wrench 3 needs to be removed, the wrench 3 can be removed from the U-shaped hook 1 204 and the U-shaped hook 2 206.

[0031] Specifically, the holding mechanism 1 includes an arc-shaped handle 101 , and a circular hole 102 is formed on a surface of one end of the arc-shaped handle 101 away from the connecting and fixing mechanism 2 .

[0032] As can be seen from the above, the arc-shaped handle 101 is provided to facilitate the user to hold the device, and the circular hole 102 is used to conveniently hang and store the device.

[0033] Specifically, the connecting and fixing mechanism 2 also includes a connecting handle 201, one end of the connecting handle 201 is fixedly installed on one end of the arc-shaped handle 101, the other end of the connecting handle 201 is fixedly installed with a bending handle 202, one end of the bending handle 202 is fixedly installed with a fixing handle 203, the fixing handle 203 and the connecting handle 201 are parallel to each other, a U-shaped hook 1 204 is fixedly installed on one end of the fixing handle 203, and a U-shaped hook 206 is fixedly installed on the outer wall of one side of the bending handle 202 close to the outer side of the U-shaped hook 1 204.

[0034] As can be seen from the above, a bent handle 202 is set between the connecting handle 201 and the fixed handle 203, and a gap is left between the bent handle 202 and the tail end of the wrench 3, which is convenient for avoiding the wrench 3. The end of the wrench 3 is fixed by U-shaped hook 1 204 and U-shaped hook 2 206, so as to facilitate the use of the device to tighten or remove the bolts.

[0035] Specifically, a threaded hole is formed on an outer wall of one side of the U-shaped hook 206 , a stainless steel screw 205 is screwed into the inner part of the threaded hole, and one end of the stainless steel screw 205 is against an outer wall of one side of the wrench 3 .

[0036] As can be seen from the above, the stainless steel screw 205 is used to hold one end of the wrench 3, thereby preventing the wrench 3 from loosening during operation.

[0037] Working principle: When in use, the user holds the arc-shaped handle 101 of the device and aligns one end of the wrench 3 with the bolt, and then uses the device to tighten or remove the bolt. During the last tightening and the first removal, the device can be used to apply force, and the remaining operations can be performed by the wrench 3 itself. When the wrench 3 needs to be removed, the stainless steel screw 205 is turned out to loosen the restraint on the wrench 3, and the wrench 3 can be removed from the U-shaped hook 1 204 and the U-shaped hook 2 206.
