[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Embodiment 1:

[0022] like Figure 1-4As shown, the utility model is a tool-free adjustment clamp, including a clamp mounting block 10 and an adjustable block 20. Adjustment plates 201 are formed on both sides of the adjustable block 20. A plurality of adjustment holes 202 are arranged on the adjustment plates 201. The adjustment holes 202 are connected and arranged in the same row. A track 203 for the clamp mounting block 10 to move is formed between the adjustment plates 201. A fixing hole 101 is formed at one end of the clamp mounting block 10 located on the track 203. A spring 102 is arranged in the fixing hole 101. Fastening components 30 for fixing the clamp are arranged on both sides of the spring 102. The fastening components 30 include a fixing block 301 and a rotating handle 302. The fixing block 301 is placed in the adjustment hole 202. The rotating handle 302 is screwed in a rotating manner so that the fixing block 301 is embedded in the fixing hole 101 and abuts against the spring 102. The clamp mounting block 10 adopts different forms according to the type of the cylinder 40. If it is a two-claw manipulator, it adopts the following forms: Figure 1-Figure 4 The fixture mounting block 10 is relatively long and has a hole formed on the inner side for fixing the fixture. Figure 5-Figure 6 The clamp mounting block 10 shown is relatively short in length and has a hole formed on its upper end surface for fixed connection with the clamp.

[0023] The fixing block 301 includes a first part 301a located in the adjustment hole 202 and a second part 301b located in the fixing hole 101, a threaded hole is provided in the first part 301a, the rotating handle 302 includes an operating part 302a and a screw part 302b, the screw part 302b is adapted to be arranged in the threaded hole, and the second part 301b has an action groove 301b1 that abuts against the spring 102.

[0024] The adjustment plate 201 is bent at one end close to the clamp mounting block 10 to form a guide bar 2011, and a corresponding guide groove 103 is formed on the clamp mounting plate. When the clamp mounting block 10 moves, the guide bar 2011 is embedded in the guide groove 103 and moves along the direction of the guide bar 2011, thereby improving the guiding effect of the clamp mounting block 10 when moving.

[0025] A mounting hole 204 is formed on one end of the adjustable block 20 away from the rail 203 for connection with the cylinder 40 .

[0026] Embodiment 2:

[0027] like Figure 5 As shown, the utility model also provides a two-claw manipulator having the above-mentioned tool-free adjustment fixture and cylinder 40.

[0028] Embodiment 3:

[0029] like Figure 6As shown, the utility model also provides a three-claw manipulator having the above-mentioned tool-free adjustment fixture and cylinder 40.

[0030] The adjustment principle of the utility model is as follows: slide the clamp mounting block 10 to the required position, and then tighten and fix the clamp mounting block 10 through the fastening assembly 30, and a corresponding distance mark is set on the adjustment block, so that the specific adjustment range can be seen more intuitively; the utility model increases the distance between the clamps, can adapt to a larger range of materials, and has a wider applicability.

[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0032] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0033] The above description shows and describes several preferred embodiments of the utility model, but as before, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept of this article through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
