Detailed Description

The following description is only intended to disclose the invention so as to enable any person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other arrangements without departing from the spirit and scope of the invention.

As shown in figure 1 and figure 2, the utility model provides a clamp pincers with test utensil can be used to the check clamp installation back between the ear both sides wall clearance size whether accord with the specification to it is firm to judge whether the clamp installation. Specifically, the clamp pliers with the test tool comprise two pliers heads 10, two pliers handles 20 and a test tool 30.

Each head 10 is provided with engagement teeth 11 and a cutting edge 12 for cutting. The shape and number of the engaging teeth 11 may be different according to actual needs, for example, the engaging teeth 11 may be mountain-shaped or wave-shaped. The end of each binding clip 10 also has a first connection hole 101. The middle portion of each binding clip 10 is further provided with a fourth connecting hole 102. In addition, each binding clip 10 has a positioning recess 103. Optionally, in this embodiment, the positioning recess 103 is adjacent to one of the engagement teeth 11.

The two forceps handles 20 are respectively connected with the two forceps heads 10 into a whole in a one-to-one correspondence manner. That is, one of the handles 20 is integrally connected to one of the bits 10, and the other handle 20 is integrally connected to the other of the bits 10.

Specifically, the end of each handle 20 is provided with a second connecting hole 201, the clamp pliers with the test tool further comprise two fasteners 40, and the two fasteners 40 respectively pass through one of the first connecting holes 101 and one of the second connecting holes 201 in sequence, so that the pliers head 10 and the handles 20 are connected together. Optionally, the fastener 40 is a pin or a screw.

The two pliers heads 10 or the two handles 20 are connected together in a rotatable manner, so that by actuating the two handles 20, the two pliers heads 10 are opened or closed together, respectively, so that the clamping or cutting function of the band clamp is achieved. In this embodiment, each of the forceps handles 20 has a third connecting hole 202, and the band clamp with the testing tool further includes a pin 50, and the pin 50 sequentially passes through the third connecting holes 202 of the two forceps handles 20, so that the two forceps handles 20 are rotatably connected together by the way that the pin 50 sequentially passes through the two third connecting holes 202. When in use, the pliers handle 20 is held by hand, and the two pliers heads 10 are correspondingly opened or combined together by operating the pliers handle 20 to open or combine together, so as to complete the crimping or cutting function.

In other embodiments, the two jaws 10 may be pivotally connected together to perform the basic function of a band clamp, such as crimping or cutting. For example, a through hole may be formed in the binding clip 10, and the pin 50 may sequentially pass through the through holes formed in the binding clip 10, so that the two binding clips 10 can rotate around the pin 50 to open or close the binding clips 10.

In addition, the band clamp with the testing tool further comprises two fixing pins 60 and two cover plates 70, and each cover plate 70 is provided with two through holes 701 which are distributed at intervals. The two cover plates 70 are respectively located on both sides of the binding clip 10, so that the two binding clip 10 are both located between the two cover plates 70. The two fixing pins 60 are inserted through one of the through holes 701 of the two cover plates 70 and the fourth connecting hole 102 of one of the bits 10, respectively, so that the two cover plates 70 and the two bits 10 are connected together, and the two bits 10 are respectively rotated about the two fixing pins 60.

The clamp pliers with the testing tool further comprise a positioning shaft 80, and the positioning notches 103 of the two pliers heads 10 are matched with the positioning shaft 80. The positioning notches 103 of the two forceps heads 10 are respectively positioned at two sides of the positioning shaft 80 and are matched with the positioning shaft 80, and the positioning shaft 80 is positioned in a space formed by the positioning notches 103 of the two forceps heads 10. It should be noted that in other embodiments, the clamp with the test tool may omit the positioning shaft 80.

When using the band clamp with the testing tool, a user holds the two clamp handles 20 and opens or combines the two clamp handles 20 together, and the two clamp handles 20 correspondingly drive the two clamp heads 10 to rotate around the two fixing pins 60 one by one, so that the two clamp heads 10 are opened or combined synchronously to realize the crimping or shearing function.

The test tool 30 is mounted to the bit 10 or the handle 20. Optionally, in the present embodiment, the test tool 30 is mounted on one of the handles 20. Specifically, the clamp 30 is a metal rod, the clamp 30 has an end 31 with a predetermined size, after the clamp is mounted by using a clamp pliers, the end 31 of the clamp 30 is inserted into a gap formed between two side walls of an ear of the clamp, and the size of the end 31 of the clamp 30 is matched with the allowable maximum gap size to check whether the ear gap of the clamp is smaller than a predetermined specification, so as to judge whether the clamp is mounted stably. For example, when the maximum allowable size of the gap formed between the side walls of the ears of the clip is 2mm during the connection of the water pipe by the clip, the diameter of the end portion 31 of the jig 30 is 2 mm. When the end 31 of the test tool 30 can be inserted into the gap, it is said that the actual gap is greater than the allowed 2mm specification and the clip installation is not robust and acceptable. On the contrary, only when the end 31 of the testing device 30 can not be inserted into the gap, it indicates that the actual gap size is less than 2mm, which is satisfactory, and the clip is stable and qualified when being installed.

Optionally, in the present embodiment, the test tool 30 is L-shaped, and one end of the test tool 30 is rotatably mounted on one of the forceps handles 20. Specifically, one end of the test tool 30 is bent to form a mounting ring 301, and the mounting ring 301 is sleeved on the outer periphery of one of the fastening members 40, so that the test tool 30 is rotatably mounted on one of the forceps handles 20 through the fastening member 40. Thus, when the user needs to use the test tool 30 for verification, the test tool 30 can be rotated to enable one end of the test tool 30 to be away from the forceps handle 20 for verification; when the user does not need to use the clamp 30, the clamp 30 is rotated again, so that the clamp 30 is folded on the clamp handle 20, the size of the whole clamp is reduced, and the clamp is convenient to carry and more attractive.

In other embodiments, the test device 30 may be in the shape of a straight line.

It is to be understood by persons skilled in the art that the embodiments of the present invention described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the invention have been shown and described in the embodiments without departing from the principles of the invention, embodiments of the invention may be subject to any deformation and modification.
