It should be noted that, in order to ensure long service life, stable operation and certain texture, the tool clamp of the present scheme is made of a metal material, such as but not limited to stainless steel.

In one embodiment, the fixing base 10 includes a fixing ring 11, a fixing block 12 and a fastening component 13, and the fixing ring 11 is fixed on the fixing block 12 through the fastening component 13. In this embodiment, the fixed block 12 is a square stainless steel block, and can serve as an operation platform, and the tool clamp has a large weight, so that the whole tool clamp is prevented from being stressed and slipping when the operation rotary seat 20 rotates, and the operation efficiency and the experience are not affected. The upper surface of the fixed block 12 is provided with three screw holes, the fastening assembly 13 comprises three bolts, the three bolts are screwed in the screw holes in a one-to-one correspondence manner, and the fixed ring 11 is positioned among the three bolts and is buckled and fixed by the bolt head. The fixing seat 10 is simple in structure, beneficial to reducing the manufacturing cost, convenient to assemble and disassemble and convenient to maintain, store and transport subsequently.

Of course, in other embodiments, the fixing ring 11 may be integrally formed with the fixing block 12; or the fastening component 13 is a clamping body and a clamping position which are respectively arranged on the fixed ring 11 and the fixed block 12, and the assembly and fixation are realized through the clamping connection of the clamping body and the clamping position.

Referring to fig. 1, the rotating base 20 includes a rotating ring 21 and a tray 22 disposed on an inner circumferential wall of the rotating ring 21. During clamping, the buttons are directly arranged on the tray 22, and the tray 22 supports the buttons. However, it should be noted that the thickness of the tray 22 is smaller than that of the rotary ring 21, in other words, the upper surface of the tray 22 needs to be lower than that of the rotary ring 21, and at this time, the rotary base 20 can form an inner cavity structure, and the button can be more stably placed on the tray 22 by being limited by the inner annular wall of the rotary ring 21.

The rotating ring 21 is rotatably nested in the ring cavity of the fixed ring 11. In order to ensure the rotating ring 21 to rotate smoothly, it is preferable that the inner diameter of the fixed ring 11 is adapted to the outer diameter of the rotating ring 21, so that the outer annular wall of the rotating ring 21 can contact with the inner annular wall of the fixed ring 11, and the rotating ring 21 is constrained and guided by the inner annular wall of the fixed ring 11 to rotate stably.

Referring to fig. 1, the clamping arm 41 includes a mounting end 411 and a clamping end 412 disposed opposite to each other, the mounting end 411 has a first mounting portion and a second mounting portion, the transmission assembly includes a first transmission member 42 and a second transmission member 43, the first mounting portion is rotatably connected to the fixed ring 11 through the first transmission member 42, and the second mounting portion is rotatably connected to the rotating ring 21 through the second transmission member 43. At this time, the first transmission member 42 on the fixed ring 11 forms a rotation base point, and the second transmission member 43 on the rotating ring 21 forms a push-pull point; when three clamping arms 41 need to be opened (in the preferred embodiment of the present application, the number of the clamping arms 41 is three), the driving mechanism 30 is operated clockwise, at this time, the rotating ring 21 rotates clockwise, the second transmission member 43 rotates and pushes the clamping arms 41 to form a tendency of swinging towards the external direction, and finally rotates and expands outwards around the first transmission member 42, that is, the three clamping arms 41 synchronously rotate and move away from each other to expose the maximum area of the tray 22, so that the buttons can be conveniently placed on the tray 22, and the preliminary clamping of the buttons can be completed. After the button is placed, the driving mechanism 30 is operated again counterclockwise, the rotary ring 21 is rotated and reset in the counterclockwise direction, at this time, the second transmission piece 43 rotates and pulls the clamping arms 41 to swing towards the inner direction, and finally the clamping arms rotate inwards around the second transmission piece 43 and are folded, namely the three clamping arms 41 rotate towards each other synchronously to approach to clamp and fix the button, so that the three clamping ends 412 finish final clamping of the button.

It will be appreciated that the clamping ends 412 cooperate to define a clamping cavity, which is the area enclosed by the upper surface of the tray 22 and each clamping arm 41. When the button is in the unfolding state, the clamping cavity is in the maximum area and volume state, buttons with different diameters can be placed without interference, and the applicability is strong; when the button is in a furled state, the three clamping arms 41 synchronously rotate to close and can be maintained at different gathering degrees, so that the button can flexibly adapt to buttons with different diameters, and the applicability is extremely strong.

In addition, considering that the position of the button initially placed on the tray 22 is random, the button is often deviated to a side away from the center of the tray 22, and the button may jump or splash due to the excessively light weight of the button during the pushing process of the button by the arms 41 and the moment when the arms 41 start to clamp the button. In this regard, in a further embodiment, each of the clamping ends 412 is further provided with a button body 44, and each of the button bodies 44 is located above the clamping cavity and cooperates to form an anti-trip structure. In this way, the button body 44 can restrain the button from above, so as to restrain the button from jumping off the tray 22 in the longitudinal direction, which affects the button clamping efficiency and the operation experience.

Referring to fig. 1, in the present embodiment, the structural shape and size of the clamping arm 41 can be designed according to the actual needs of those skilled in the art. In a preferred embodiment, however, the shape of the clamping arm 41 changes gradually from the mounting end 411 to the clamping end 412 in an arc transition. That is, the clamp arms 41 are formed in an arc-shaped arm configuration with the arc-shaped bending direction toward the center of the tray 22. Therefore, the clamping arms 41 can rapidly unfold or fold the clamping ends 412 by only swinging a small stroke, which is beneficial to improving the clamping efficiency of the button and improving the testing work efficiency.

In this scheme, for the convenience of manufacturing and assembly molding, first installation department is first installation through-hole, the second installation department is second installation through-hole, first driving medium 42 is first commentaries on classics round pin, second driving medium 43 is second commentaries on classics round pin, first commentaries on classics round pin wears to locate first installation through-hole and with the fastening of fixed ring 11, the second commentaries on classics round pin wears to locate second installation through-hole and with rotatory ring 21 fastens. Therefore, the clamping arm 41 can realize stable swinging expansion or folding by taking the first rotating pin as a rotating base point; meanwhile, the second rotating pin serves as a push-pull force application body, driving force formed by rotation of the rotating ring 21 in different directions is effectively converted into pushing force or pulling force, and then the clamping arm 41 is pushed to be unfolded or pulled to be folded, so that the work state of the tool clamp is rapidly switched, the high-efficiency test requirement is met, and the use experience is improved.

As described in the above scheme, the rotating ring 21 and the fixed ring 11 in the scheme are of an inner-outer nested structure, and the rotating ring and the fixed ring are in contact with each other through annular planes to ensure firm assembly and stable rotation. However, the excessive circumferential contact area also causes a large frictional resistance, which causes a problem that a large amount of force is required to rotate the rotary ring 21. Based on this, in a further embodiment, the tool fixture further includes a rolling body and a limiting frame, a rolling groove is formed in an inner annular wall of the fixed ring 11 and/or an outer annular wall of the rotating ring 21, and the rolling body is embedded in the rolling groove in a rolling manner through the limiting frame. Therefore, the rolling bodies roll in the rolling grooves, so that the friction force between the rotating ring 21 and the fixed ring 11 can be effectively reduced while the rotating ring rotates smoothly, and the purposes of saving labor in operation and improving use experience are achieved. And, through install the spacing additional in the outside of rolling element, can prevent that the rolling element from excessively gathering together at the local region of rolling groove, lead to the existence of other regions not having the rolling element, cause rotatory ring 21 still to contact with fixed ring 11 face, do benefit to and promote rolling element rolling reliability.
