[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.
[0023] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.
[0024] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0026] like Figure 1 and Figure 2 As shown, an adjustable crimping pliers includes an upper pliers head 1, a lower pliers head 2 and a handle 5, characterized in that: the upper pliers head 1 is provided with a first adjustment button 101, the lower pliers head 2 is provided with a second adjustment button 201, the first adjustment button 101 is provided with a first adjustment tooth 102, the second adjustment button 201 is provided with a second adjustment tooth 202, a crimping space is formed between the first adjustment tooth 102 and the second adjustment tooth 202, and the size of the crimping space is changed by rotating the first adjustment button 101 and the second adjustment button 102. The space difference between the crimping spaces corresponds to the size of cables suitable for different sizes. The handle 5 is fixedly connected to the upper pliers head 1 and the lower pliers head 2 by a fixing nut 104, and a non-slip sleeve 501 is provided on one side of the handle 5.
[0027] like Figure 2As shown, the upper clamp head 1 and the lower clamp head 2 rotate by engaging with the rotating teeth 203. When the upper clamp head 1 and the lower clamp head 2 rotate during the wire crimping process, a state similar to dynamic engagement is formed. The upper clamp head 1 and the lower clamp head 2 are fixedly connected by the connecting plate 3 to prevent the upper clamp head 1 and the lower clamp head 2 from being misaligned during use, so that the upper clamp head 1 and the lower clamp head are not on the same plane. A clamping plate 4 is arranged inside the upper clamp head 1, and the clamping plate 4 itself is provided with a through hole and is fixedly connected to the upper clamp head 1 through a fixing pin. A limiting column 403 and a limiting plate 401 are arranged on the clamping plate 4, and the limiting column 403 and the limiting plate 401 are connected by a spring 402. Limiting bosses 404 are arranged on both sides of the lower part of the limiting plate 401, and the limiting bosses 404 are used to prevent the limiting plate 401 from sliding outward in the vertical direction because no constraint support is arranged at the bottom of the limiting plate 401.
[0028] like Figure 2 and Figure 3 As shown, the limit plate 401 contacts the horizontal surface on the first adjusting tooth 102. When the crimping pliers are in the process of crimping, the crimping space formed by the first adjusting tooth 102 and the second adjusting tooth 202 is used to crimp the cable. The reaction force formed by the extrusion of the cable is transmitted to the horizontal surface of the first adjusting tooth 102, and then transmitted to the spring 402 through the limit plate 401. Through the elastic force, the first adjusting tooth is elastically supported. In terms of actual use effect, the crimping pliers can have a better elastic feedback feel during use, which is convenient for perceiving the working state of the crimping pliers. The upper clamp head 1 and the lower clamp head are symmetrically distributed structures.
[0029] like Figure 4 As shown, B represents a wire pressing space formed between the first adjusting tooth 102 and the second adjusting tooth 202. The horizontal contact surfaces of the first adjusting tooth 102 and the second adjusting tooth 202 are unequal length structural layouts. Correspondingly, a variety of wire pressing spaces are formed between the first adjusting tooth 102 and the second adjusting tooth 202 to meet the wire pressing requirements of different cable sizes.
[0030] When using the crimping pliers, first open the handle 5 outward, then rotate the first adjustment button 101 and the second adjustment button 201, then put the cable to be crimped into the crimping space formed between the first adjustment tooth 102 and the second adjustment tooth 202, and adjust the first adjustment button 101 and the second adjustment button 201 again so that the cable is tightly pressed by the first adjustment tooth 102 and the second adjustment tooth 202. Then apply pressure to the handle to complete the crimping process of the cable.
[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
