[0029] To make the objectives, advantages, and features of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to conveniently and clearly illustrate the objectives of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0030] Figure 1 This diagram shows a partial structural schematic of the clamping tool kit provided in some embodiments of the present invention in one state. Figure 2 A partial structural schematic diagram of the workpiece clamping kit in another state is shown. Figure 3 The clamping tool kit is shown in Figure 2 A partial sectional view in the indicated state. For example... Figures 1 to 3 As shown, the clamping tool kit includes a clamping arm mechanism 100 and a chuck assembly 200. The structure of the clamping arm mechanism 100 is as follows: Figure 4As shown, the clamping arm mechanism 100 comprises two clamping arms 110 and a first joint 120. The two clamping arms 110 are rotatably connected. Each of the clamping arms 110 has opposite first and second ends, the first end is formed as a ring-shaped handle 1101, and the second end is provided with the first joint 120. The chuck assembly 200 comprises a chuck 210 and a second joint 220, the chuck 210 is provided with the second joint 220. The second joint 220 is detachably connected with the first joint 120.

[0031] It can be understood that when the two clamping arms 110 of the clamping arm mechanism 100 are connected with the two chucks 210 of the same chuck assembly 200, the clamping arm mechanism 100 and the chuck assembly 200 together form a clamping device, which can be used to clamp parts.

[0032] According to the shape of the chuck 210, the chuck 210 can be divided into different types, for example, when the end of the chuck 210 away from the second joint 220 is a pointed end, the chuck 210 can be divided into a pointed chuck; for another example, when the end of the chuck 210 away from the second joint 220 is a flat structure, the chuck 210 can be divided into a flat chuck, and so on.

[0033] By providing the first joint 120 on the clamping arm 110, the clamping arm 110 can be connected with the chuck 210 of a suitable type as needed, for example, when clamping a chip tube, the clamping arm 110 is connected with the pointed chuck having a pointed end; for another example, when clamping a capacitor or a resistor, the clamping arm 110 is connected with the flat chuck having a flat end. In this way, the clamping arm 110 can be adapted to different chucks 210 for different scenarios, and the clamping arm mechanism 100 and the chuck assembly 200 together form different types of clamping devices, thereby adapting to different application scenarios, which enables enterprises to reduce the investment cost of clamping devices. Moreover, when the chuck 210 is damaged, the operator only needs to scrap the damaged chuck 210, without scrapping the entire clamping device, thereby reducing the use cost.

[0034] Optionally, the first joint 120 and the second joint 220 can have any suitable form as long as they can be connected together. In the preferred embodiment, the first joint 120 comprises a groove provided on the end surface of the second end. Correspondingly, the second joint 220 comprises a protrusion connected to the chuck 210, which is used to be inserted into the groove. In other words, the chuck 210 is pluggably connected to the clamp arm 110, which makes it convenient and fast for the operator to replace the chuck 210. Of course, the positions of the groove and the protrusion can be interchanged, i.e. the protrusion is provided on the end of the second end of the clamp arm 110 as the first joint 120, and the groove is provided on the end surface of one end of the chuck 210 as the second joint 220.

[0035] The two clamp arms 110 are rotatably connected so that the clamp arms 110 form a scissor-like structure, and the first end forms a ring-shaped holding portion 1101, which is more ergonomic and convenient for the operator to hold, and the force applied by the operator on the two clamp arms 110 is more balanced, which makes it easier to clamp the article or perform the corresponding operation when using the clamping device. Preferably, the outer contour of the holding portion 1101 is arc-shaped, so that when the operator's thumb and index finger are inserted into the holding portion 1101 of one of the clamp arms 110, the outer part of the holding portion 1101 better fits the shape of the palm, improving the comfort of the operator.

[0036] It can be understood that the two clamp arms 110 are rotatably connected by a pin shaft 130, which constitutes the rotation axis when the two clamp arms 110 rotate relative to each other. The distance from the end of the second end of the holding portion 1101 to the pin shaft 130 is greater than the distance from the end of the second end to the pin shaft 130. In this way, the clamp arm mechanism 100 forms a labor-saving lever structure, making it easier and less tiring for the operator to use the clamping device.

[0037] Optionally, the distance from the end of the second end of the holding portion 1101 to the pin shaft 130 is 8-12 cm, and the distance from the end of the second end to the pin shaft 130 is 3-6 cm. The advantage of this size is that when clamping parts using the clamping device, the operator can operate with the hands far away from the parts, on the one hand avoiding static electricity caused by the hands being too close to the parts, on the other hand reducing the obstruction of the hands to the operating field of view, making it convenient for the operator to observe the sample state, which helps to accurately clamp and unload the sample, and on the other hand it is also beneficial for the operator to more flexibly use the wrist and arm strength to control the direction and force of the sample clamping.

[0038] Optionally, the clamping arm 110 comprises a first segment and a second segment connected to each other, one end of the first segment away from the second segment constitutes the first end and is formed into the holding part 1101, and one end of the second segment away from the first segment constitutes the second end. The outer surface of the first segment is configured to have insulation. When the operator uses the clamping device, the operator's hand contacts the outer surface of the first segment, and static electricity can be avoided between the operator's hand and the clamping arm mechanism 100.

[0039] Optionally, the clamping arm 110 comprises a metal clamping arm body 111 and an insulating coating layer 112, the insulating coating layer 112 is coated on the outer surface of the part of the clamping arm body 111 at the first segment, thereby achieving the purpose of the outer surface of the first segment having insulation, and at the same time, the clamping arm 110 has a longer service life.

[0040] The metal used to manufacture the clamping arm body 111 is preferably 316 stainless steel, which has good welding performance due to low carbon content, does not require heat treatment after welding, and has no tendency to knife edge corrosion after welding. The coating layer 112 can be formed by adhering or sleeving a rubber or other high molecular material on the outer surface of the part of the clamping arm body 111 corresponding to the first segment, or the coating layer 112 is an insulating coating formed by curing an insulating paint coated on the outer surface of the part of the clamping arm body 111 corresponding to the first segment.

[0041] It should be noted that the foregoing describes some advantages of the clamping arm mechanism 100 by taking the clamping device for clamping parts as an example, but in practice, the clamping device can also be used to perform non-clamping operations, such as flattening the surface of a part.

[0042] Further, the clamping tool kit preferably comprises a plurality of the chuck assembly 200, and the shapes and / or sizes of the chucks 210 of different chuck assemblies 200 are different. In actual use, the clamping arm 110 of the clamping arm mechanism 100 is selectively connected with the chuck 210 of one chuck assembly 200.

[0043] In addition, the chuck 210 is preferably made of an insulating material to avoid static electricity between the chuck 210 and the parts or other components in contact with it. An optional insulating material is, for example, polyether ether ketone (PEEK), which has the characteristics of high temperature resistance, corrosion resistance, and fire resistance.

[0044] Although the utility model discloses as above, but is not limited to this. The person skilled in the art can make various changes and variations to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model are within the scope of the claims of the utility model and its equivalent technologies, then the utility model also intends to include these changes and variations.
