Abstract
Description
Technical Field
[0001] This application relates to the technical field of tools for assembling earless clamps, and more particularly to a pair of pliers for earless clamps. Background Art
[0002] Currently, in order to adapt to the use in narrow spaces, a half-shaft constant velocity joint boot uses an earless endless clamp, and this clamp requires special tools.
[0003] Generally, there are two types on the existing market, namely pneumatic pliers and manual pliers. The pneumatic pliers have a higher cost and are relatively expensive to purchase. The manual pliers are similar in shape to a pair of vise-grip pliers. In the narrow space under the vehicle, it is not easy to apply a large force, and the clamping force is insufficient.
[0004] Therefore, it is urgent to develop a pair of pliers that can output a large clamping force and stability in a narrow space. Utility Model Content
[0005] The purpose of this application is to provide a pair of pliers for earless clamps, which can be adapted to use in narrow spaces to solve the problems raised in the above background art.
[0006] To achieve the above purpose, this application provides a pair of pliers for earless clamps by adopting the following technical solutions:
[0007] A pair of pliers for earless clamps includes a handle, a fixed arm, a movable arm, an adjusting rod, a female end chuck and a male end chuck. The fixed arm is fixed on the handle. The movable arm is hinged to the side of the fixed arm, and the end of the movable arm can approach the end of the fixed arm. Through grooves are formed in both the fixed arm and the movable arm, and joint shafts are rotatably connected in the through grooves. The adjusting rod is threadedly penetrated and connected to the two joint shafts. The male end chuck is fixed on the end face of the fixed arm, and the female end chuck is fixed on the end face of the movable arm. The male end chuck is adapted to the female end chuck.
[0008] Preferably, in order to ensure the stable operation of the pliers, a guiding block is provided on the side wall of the male end chuck near the bottom, and a guiding groove is formed at the position of the female end chuck corresponding to the guiding block.
[0009] Preferably, clamping heads are correspondingly arranged on the upper side wall and the front and rear side walls of the male end chuck and the female end chuck.
[0010] By adopting the above technical solutions, clamping heads are correspondingly arranged on the upper side wall and the front and rear side walls of the male end chuck and the female end chuck, which is convenient for the staff to select a suitable clamping head for use.
[0011] Preferably, in order to facilitate applying a clamping force to a wrench, the end of the adjusting rod has a nut head, and a blind groove for placing a ratchet wrench is formed on the surface of the nut head.
[0012] The side part of the female end chuck can abut against the side part of the male end chuck to achieve terminal stop.
[0013] In summary, the present application includes at least one of the following beneficial technical effects: the clamp for the earless clamp has a simple structure, is easy to manufacture, and has a low manufacturing cost. By using the adjusting rod to drive the movable arm to move towards the fixed arm, when adjusting the adjusting rod, a ratchet wrench is used for adjustment, and the space occupancy rate is small, which is suitable for operating in the narrow space under the vehicle bottom, greatly improving the disassembly and assembly efficiency.

[0017] The following will further describe the present application in detail Figure 1-2 in conjunction with the accompanying drawings.
[0018] The embodiment of the present application discloses a clamp for an earless clamp. Referring to Figure 1-2 , it includes a handle 1, a fixed arm 2, a movable arm 3, an adjusting rod 4, a female end chuck 5 and a male end chuck 6. The fixed arm 2 is fixed on the handle 1, the movable arm 3 is hinged to the side of the fixed arm 2, and the end of the movable arm 3 can approach the end of the fixed arm 2. Through grooves are opened on both the fixed arm 2 and the movable arm 3, and joint shafts 7 are rotatably connected in the through grooves. The adjusting rod 4 is threadedly penetrated and connected to the two joint shafts 7. The male end chuck 6 is fixed on the end face of the fixed arm 2, the female end chuck 5 is fixed on the end face of the movable arm 3, the male end chuck 6 is adapted to the female end chuck 5, and clamp heads 8 are correspondingly arranged on the upper side wall and the front and rear side walls of the male end chuck 6 and the female end chuck 5.
[0019] Referring to Figure 2 , a guide block 61 is provided on the side wall of the male end chuck 6 near the bottom, a guide groove 51 is opened at the position of the female end chuck 5 corresponding to the guide block 61, and the side part of the female end chuck 5 can abut against the side part of the male end chuck 6 to achieve terminal stop.
[0020] Referring to Figure 1 , in order to facilitate the application of external force, the end of the adjusting rod 4 has a nut head 41, and a blind groove 411 for placing a ratchet wrench is opened on the surface of the nut head 41.
[0021] The implementation principle of the clamp for earless clamp in the embodiments of the present application is as follows:
[0022] During use, the staff holds the handle 1 and hooks the tip of the clamping head 8 of the male end chuck 6 and the female end chuck 5 to the tension hook and the load hook respectively. The other hand holds the ratchet wrench and rotates the adjusting rod 4 to make the movable arm 3 rotate towards the fixed arm 2, compressing the diameter of the clamp until there is no displacement on the hook, and then the locking of the clamp can be completed;
[0023] When disassembling the clamp, the tip of the clamping head 8 is aligned with the grooves at both ends of the clamp and force is applied. Slightly shrinking the diameter of the clamp by the applied force can make the hook loosen and disengage from the groove.
[0024] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
