[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0032] Embodiment 1:
[0033] Refer to Figures 1 - 3 , a multifunctional type III elastic strip wrench that can be quickly assembled provided by the present utility model includes a mounting seat A1. The inner wall of the mounting seat A1 is provided with internal threads, and an elastic strip wrench 2 is threadedly connected to the inner wall of the mounting seat A1. The elastic strip wrench 2 is a prior art, and the bottom end of its outer wall is connected with a rod body, and external threads are provided on the outside of the rod body. By rotating the elastic strip wrench 2 to rotate inside the inner wall of the mounting seat A1, the whole can be conveniently replaced. The outer wall of the mounting seat B4 is provided with external threads, and an adjustable wrench 5 is threadedly connected to the external threads of the mounting seat B4. The adjustable wrench 5 is a prior art, and there is also a set of rod bodies at its bottom end. By providing internal threads inside the rod body, it fits with the external threads of the mounting seat B4, so that the connection between the mounting seat B4 and the adjustable wrench 5 can be quickly fixed. A telescopic mechanism 3 is provided on the right outer wall of the mounting seat A1.
[0034] Refer to Figures 2 - 3The telescopic mechanism 3 includes a fixed rod 31, the right outer wall of the fixed rod 31 is fixedly connected to the outer wall of the mounting seat B4, and the sliding rod 32 is fixedly connected to the outer wall of the mounting seat A1. When the sliding rod 32 or the fixed rod 31 moves, it will drive the corresponding mounting seat A1 and the mounting seat B4 to move synchronously, so as to adjust the overall length to facilitate the construction operation of the staff. The inner wall of the fixed rod 31 is slidably connected to the sliding rod 32, and the left inner wall of the sliding rod 32 is elastically connected to the slider 34 through the limit spring 33. The limit spring 3 One end of the limit spring 33 is fixedly connected to the inner side wall of the sliding rod 32, and the other end of the limit spring 33 is fixedly connected to the outer wall of the slider 34. The function of the limit spring 33 is to quickly fix the position of the slider 34 after it is moved outward. The slider 34 is slidably connected to the inner side wall of the sliding rod 32. Two groups of positioning posts 36 penetrate and are slidably connected to the inner wall of the sliding rod 32. The inner wall of the sliding rod 32 is provided with two groups of upper and lower guide grooves corresponding to the positioning posts 36, so that the positioning posts 36 can only move up and down on the sliding rod 32 and cannot be separated from its inner wall.
[0035] Reference Figure 3 The end of the slider 34 away from the limit spring 33 is hinged with two sets of hinged rods 35, and the ends of the two sets of hinged rods 35 away from the slider 34 are hinged with positioning columns 36. When the slider 34 moves forward and backward on the inner wall of the sliding rod 32, the two sets of positioning columns 36 will be pulled to move toward each other or away from each other through the hinged rod 35. The inner side wall of the fixed rod 31 is provided with two rows of through holes in an upper and lower direction. The positioning columns 36 are plugged into the inner wall of the through hole. The plugging between the two can fix the sliding rod 32 at multiple positions of the inner wall of the fixed rod 31 through the positioning columns 36, thereby adjusting the telescopic The overall length of the mechanism 3 is convenient for the staff to operate the spring wrench 2 or the movable wrench 5 to perform the operation. A guide groove is provided on the surface of the fixed rod 31, and the protrusion of the slider 34 passes through and is slidably connected to the inner wall of the guide groove of the fixed rod 31. The right outer wall of the fixed rod 31 is fixedly connected with a mounting seat B4. The outer wall of the slider 34 is provided with a protrusion, and the protrusion of the slider 34 passes through and is slidably connected to the inner wall of the sliding rod 32. By providing guide grooves on the surfaces of the sliding rod 32 and the fixed rod 31, the slider 34 will not be blocked by the sliding rod 32 or the fixed rod 31 when moving.
[0036] In this embodiment, during use, when the working length of the spring bar wrench 2 or the adjustable wrench 5 is too short and it is strenuous to operate, the slider 34 can be toggled to move inside the inner wall of the sliding rod 32, causing the limiting spring 33 to be elastically compressed. At this time, the two hinge rods 35 will move synchronously with the slider 34, thereby driving the two positioning columns 36 to move towards each other to disengage from the through hole at the current position of the fixed rod 31. At the same time, the sliding rod 32 can be directly moved inside the inner wall of the fixed rod 31 to adjust the overall length of the telescopic mechanism 3. When moved to a suitable position, releasing the slider 34 will cause it to be affected by the limiting spring 33 to restore the hinge rod 35 and the positioning column 36 to their initial positions synchronously, so as to be inserted into the through hole at the current position of the fixed rod 31 to fix the position after the sliding rod 32 extends. At this time, the external thread of the spring bar wrench 2 can be rotated quickly with the internal thread of the mounting seat A1 for quick threading fixation for operation. At the same time, on the right side, the internal thread of the adjustable wrench 5 can be thread-fixed with the external thread at the mounting seat B4.
[0037] Embodiment Two:
[0038] Referring to Figure 4 , a hammer 6 is detachably installed on the outer wall of the mounting seat B4, and a crowbar 7 is detachably installed on the inner wall of the mounting seat A1. Both the hammer 6 and the crowbar 7 are common in the prior art.
[0039] In this embodiment, during use, it can be switched for use when dealing with various situations on the railway. Also, the inner wall of the hammer 6 is provided with an internal thread that fits the mounting seat B4, and the outer arm of the crowbar 7 is provided with an external thread that fits the mounting seat A1.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
