According to an aspect of the present invention, as shown in fig. 1, there is provided a clamping tool, comprising: a rod member 1, a fixing member 3 and a barb 2. The rod member 1 has a first end 11 (e.g., left end in fig. 1) and a second end 12 (e.g., right end in fig. 1) opposite to each other, wherein the second end 12 extends from the first end 11 along a first direction I (e.g., left-to-right direction in fig. 1). The first direction I is a direction from the first end 11 to the second end 12.

The fixing member 3 is arranged at the first end 11 of the rod member 1. The fixture 3 and the barb 2 may be arranged on the same side of the rod 1 and the fixture 3 may be a suction cup as shown in fig. 1, for example.

The barb 2 comprises a connecting part 21 and a hook-shaped part 22, one end of the connecting part 21 is connected with the second end 12 of the rod piece 1, the hook-shaped part 22 bends and extends from the other end of the connecting part 21 to the first end 11 of the rod piece, and the inner surface of the hook-shaped part 22 is provided with a butting part C. Thereby, the connection portion 21 and the hook portion 22 form a bent shape, wherein the connection portion 21 may be perpendicular to the rod member 1 as shown in fig. 1 and 2, but the present invention is not limited thereto, and the connection portion 21 may not be perpendicular to the rod member 1.

As an embodiment, referring to fig. 1, the hook 22 may include a first wedge 221 and a second wedge 222 connected to each other. The second wedge-shaped part 222 is connected to the second end 12 of the rod member 1 via the connecting part 21, and the thickness of the first wedge-shaped part 221 (the "thickness" herein means the dimension in the direction perpendicular to the first direction I) becomes gradually larger along the first direction I. The thickness of the second wedge-shaped portion 222 gradually increases along the first direction I, and the abutting portion C of the hook 22 approaches the connecting portion 21. That is, the inner surface S21 of the first wedge part 221 and the inner surface S22 of the second wedge part 222 are inclined in the same direction (in the opposite direction of the first direction I), and the inner surface S21 of the first wedge part 221 is inclined with respect to the top surface S1 of the rod piece 1 by a larger angle than the inner surface S22 of the second wedge part 222 is inclined with respect to the top surface S1 of the rod piece 1. The outer surfaces (not labeled) of the first wedge part 221 and the second wedge part 222 may be parallel or non-parallel to the top surface S1 of the rod member 1, which is not particularly limited by the present invention. As an example, the inner surface S22 of the second wedge-shaped portion 222 is inclined at an angle of 2.8 ° to 3.3 °, e.g. 3.18 °, with respect to the top surface S1 of the rod piece 1.

Thereby, between the hook 22 and the bar 1, a housing space is formed, the height of which gradually decreases along the first direction I, that is: in the housing space, the interval between the hook 22 and the rod 1 gradually decreases from the free end of the hook 22 to the connection 21.

In this way, when the hook portion 22 of the clamping tool of the present embodiment hooks the clamped piece (such as a circuit board described below), the clamped piece can easily enter the receiving space because the receiving space is gradually reduced, and after the clamping tool hooks the clamped piece, the fixed member 3, the rod member 1 and the abutting portion C can firmly clamp and support the clamped piece.

As another embodiment, referring to fig. 2, the hook 22 may include a first wedge 221 and a second wedge 222 connected to each other. The second wedge 222 is connected to the second end 12 of the rod 1 by a connection 21, and the thickness of the first wedge 221 is gradually increased along the first direction I. The thickness of the second wedge-shaped portion 222 gradually decreases along the first direction I, and the abutting portion C is located at the connection between the first wedge-shaped portion 221 and the second wedge-shaped portion 222. That is, the inner surface S21 of the first wedge 221 is inclined from the abutment C in the opposite direction of the first direction I with respect to the top surface S1 of the rod piece 1, the inner surface S22 of the second wedge 222 is inclined from the abutment C in the first direction I with respect to the top surface S1 of the rod piece 1, and the inner surface S21 of the first wedge 221 is inclined at a larger angle with respect to the top surface S1 of the rod piece 1 than the inner surface S22 of the second wedge 222 is inclined with respect to the top surface S1 of the rod piece 1. The outer surfaces of the first wedge part 221 and the second wedge part 222 may be parallel or non-parallel to the top surface S1 of the rod member 1, which is not particularly limited by the present invention.

Thus, between the hook 22 and the bar 1, a housing space is formed, which may gradually increase along the first direction I, that is: in the housing space, the interval between the hook portion 22 and the rod 1 gradually increases from the abutting portion C of the hook portion 22 to the connecting portion 21. The abutting portion C is located closest to the rod member 1. The distance between the holding portion C and the rod member 1 is slightly smaller than the thickness of the clamped member (such as a circuit board described below), and as an example, the distance between the holding portion C and the rod member 1 may be about 0.5mm smaller than the thickness of the circuit board. Therefore, after the clamping operation, the hook-shaped part 22 exerts the rebounding force on the clamped piece, so that the clamping force is increased, and the stable clamping is realized. The hook portion 22 is in contact with a clamped member (e.g., the circuit board 6 shown in fig. 5) only at the abutting portion C. After the hook-shaped part 22 hooks the clamped piece, the clamped piece is firmly clamped and supported by the fixing part 3, the rod piece 1 and the abutting part C.

According to the clamping tool of the present embodiment, during the clamping operation, not only the insertion of the clamped member into the housing space of the clamping tool is facilitated, but also the clamped member can be prevented from being scratched by the hook portion 22; further, during the clamping transportation, since the contact area of the clamping tool with the clamped member is significantly reduced, it is possible to prevent damage to the surface circuit or plating or the like of the clamped member due to the large-area frictional contact between the hook portion 22 and the clamped member.

In one embodiment, the edges of the rod member 1 and the hook 22 may be chamfered to smooth the transition, so as to effectively prevent the clamped member from being scratched.

The connection between the barb 2 and the rod 1 can be made in various ways. In one embodiment, as shown in fig. 1, the barb 2 is integrally formed with the rod 1, i.e., the connecting portion 21 of the barb 2 is integrally connected with the second end 12 of the rod 1. The barb 2 and the rod 1 can also be connected by means of a fixing assembly.

In another embodiment, shown in fig. 3, the barb 2 is telescopically coupled to the rod 1.

The barb 2 is telescopically connected with the rod 1, so that the whole length of the clamping tool can be adjusted conveniently to adapt to different clamped pieces. The telescopic connection can be made in many ways, for example, the barb 2 and the rod 1 can be connected by screw thread, or can be connected by sliding way. The retractable connection of the clamping tool of the present invention is not limited thereto.

In one embodiment, as shown in fig. 3, the rod member 1 may be formed as a tubular member, the connecting portion 21 of the barb 2 may be formed as an L-shaped sliding rod, the connecting portion 21 is inserted into the rod member 1, and the connecting portion 21 is slidable along the inner wall of the rod member 1.

In the present embodiment, the barb 2 and the rod 1 are telescopically connected by sliding. The length of the gripping tool is adjusted by sliding the connecting portion 21 formed as a slide rod in the rod 1 formed as a tubular member in order to adapt to different gripped members.

The positioning of the connection portion 21 with respect to the rod 1 can also be achieved in various ways. For example, in one embodiment, as shown in fig. 3, a plurality of catching grooves 211 are provided on an outer surface of the connecting portion 21 (i.e., a surface away from the hook 22) at a predetermined distance.

In one embodiment, a catch 4 is fixedly attached to second end 12 of rod 1, catch 4 being snapped into catch groove 211 to secure connecting portion 21 of barb 2 relative to rod 1.

As shown in fig. 4, grip 4 includes: support 41, latch 42, and handle 43. The handle 43, the supporting portion 41 and the locking portion 42 may be integrally formed, but the present invention is not limited thereto. In the present embodiment, the support portion 41 is substantially rectangular block-shaped and provided at the middle of the locking member 4, and the support portion 41 is fixedly connected to the rod member 1, and the connection method may be any one of, for example, welding, bonding, integral injection molding, and the like, or any other various methods capable of fixing the support portion 41 to the rod member 1, as long as the support portion 41 can abut against the rod member 1 so that the locking member 4 can swing up and down within a certain small range with the support portion 41 as a base point. The locking portion 42 extends from the support portion 41 in the first direction I and is substantially bent (for example, an inverted L shape in fig. 4), one end of the locking portion 42 is connected to the support portion 41, and a free end of the locking portion 42 is engaged with the engaging groove 211 to realize relative positioning. The handle 43 is connected to the support 41 and extends obliquely from the support 41 in a direction opposite to the first direction I and away from the rod 1.

The engaging member 4 having the above-described structure is formed by utilizing the principle of leverage, and by using the support portion 41 as a fulcrum of the lever and applying an urging force by the handle 43, the engaging portion 42 can be raised and lowered within a certain small range, and the engaging portion 42 and the engaging groove 211 are disengaged or engaged with each other, thereby positioning the connecting portion 21 and adjusting the overall length of the holding tool.

In this embodiment, retainer 4 is made of plastic, and is lightweight, low cost, and easy to manufacture. The plastic has certain flexibility and elasticity, and the pressing operation of the handle 43 is convenient. The retainer 4 may be made of other materials, such as metal.

In one embodiment, the card slot 211 is disposed on a bottom surface of the connecting portion 21 away from the hook 22; the clamping part 4 is arranged on the outer surface of the rod part 1 on the same side with the clamping groove 211.

The engaging piece 4 and the engaging groove 211 may be provided on any side of the lever 1 and the connecting portion 21, and in this embodiment, in order to prevent the engaging piece 4 from interfering with a clamped piece such as a panel or a circuit board, thereby causing damage to the clamped piece, the engaging piece 4 and the engaging groove 211 are provided on an outer surface of the connecting portion 21 away from the hook portion 22, and manual operation of the engaging piece 4 is facilitated.

In order to increase the force of the handle 43, a predetermined angle is formed between the handle 43 and the rod 1, and the predetermined angle may be an acute angle, that is, the handle 43 is tilted upward from the position of the support portion 41 to the rod 1. The predetermined angle is an acute angle of less than about 4 degrees, such as preferably 3.18 degrees.

Referring to fig. 5, in the present embodiment, the first end 11 is provided with a blind hole (not labeled), the bottom end of the fixing member 3 is shaped to correspond to the blind hole, and the fixing member 3 is fixed on the rod member 1 by clamping. As another embodiment, the fixing member 3 may be fixed to the first end 11 by adhesion.

Fig. 5 shows a cross-sectional view of a use state of a clamping tool according to an exemplary embodiment of the present invention.

Therefore, the panel 5 and the circuit board 6 need to be fixedly supported by the above-described clamping tool.

When the clamping tool of the present invention is used, the free end 62 (the right side of the circuit board 6 in fig. 5) of the circuit board 6 opposite to the connecting end 61 is hooked by the hook portion 22, and the position of the abutting portion C is closest to the rod member 1. The distance between the abutting part C and the rod piece 1 is about 0.5mm smaller than the thickness of the circuit board. Thus, after the clamping operation, the hook portion 22 exerts a repulsive force to the circuit board 6, thereby increasing the clamping force and achieving stable clamping. The hook 22 is in contact with the circuit board 6 only at the abutting portion C. After the hook-shaped part 22 hooks the clamped piece, the clamped piece is firmly clamped and supported by the fixing part 3, the rod piece 1 and the abutting part C. The clamping tool is fixed on the panel 5 through a fixing part (such as a sucker) 3, so that the clamping tool clamps the circuit board 6, fixes the circuit board 6 and the panel 5 and supports the flexible circuit board 7. The clamping tool does not cause any adverse effect such as abrasion on the connection lines on the circuit board 6 during the clamping operation and during the clamping transportation, and the clamping is stable.
