[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0029] Referring to Figure 1 and Figure 2 , the embodiments of the present application disclose a clamping tool, which comprises a clamping body, a driving device and a control switch 300.

[0030] Specifically, the clamping body comprises a handle 110 and a clamping head 120, the clamping head 120 is installed on the handle 110, the clamping head 120 comprises a first clamping part 121 and a second clamping part 122 which are rotatably connected; the driving device is used to drive the first clamping part 121 and the second clamping part 122 to rotate; the control switch 300 is arranged on the handle 110, and the control switch 300 is used to control the driving device.

[0031] In the clamping tool provided by the embodiments of the present application, the driving device can drive the first clamping part 121 and the second clamping part 122 to rotate, so that the clamping head 120 is clamped or loosened to complete the clamping action. The control switch 300 is arranged on the handle 110, which facilitates the action of the clamping head 120, and thus the convenience of the clamping operation can be improved.

[0032] It is worth understanding that the driving device can drive one of the first clamping part 121 and the second clamping part 122 to move relative to the other, so as to drive the clamping head 120 to clamp or loosen; or the driving device can drive the first clamping part 121 and the second clamping part 122 to rotate simultaneously, so as to drive the clamping head 120 to clamp or loosen.

[0033] In some embodiments of the present application, referring to Figures 1 to 3The clamping head 120 comprises a first driving arm 131 and a second driving arm 132. One end of the first driving arm 131 is connected with the first clamping part 121, and one end of the second driving arm 132 is connected with the second clamping part 122. At least one of the other end of the first driving arm 131 and the other end of the second driving arm 132 is provided with a wedge-shaped slope 133. The driving device comprises a top rod 230, which is moved relative to the wedge-shaped slope 133 to drive the first clamping part 121 and the second clamping part 122 to fold. The first clamping part 121 and the second clamping part 122 are rotatably connected through the rotating shaft 123, and rotate around the axis of the rotating shaft 123 as the rotation axis. The first driving arm 131 and the first clamping part 121 are located on the same side of the rotation axis. In this way, by driving the top rod 230 to move towards the rotating shaft 123 close to the first clamping part 121 and the second clamping part 122, the relative position of the top rod 230 and the wedge-shaped slope 133 can be changed, so as to drive the first clamping part 121 and the second clamping part 122 to clamp, so as to realize the clamping action.

[0034] Further, referring to Figure 3 As shown, the driving device comprises a guide rod 240 and a float 250. The guide rod 240 is installed on the handle 110, and the guide rod 240 has a movable cavity 241. The top rod 230 and the float 250 are movably installed in the movable cavity 241, and the top rod 230 is located between the float 250 and the first driving arm 131. The movable cavity 241 is arranged to point to the rotating shaft 123 of the first clamping part 121 and the second clamping part 122. The movable cavity 241 of the guide rod 240 can provide a guide action for the top rod 230 and the float 250, so that the float 250 can push the top rod 230 to move towards the side close to the rotating shaft 123.

[0035] It is worth understanding that the scheme of moving the float 250 in the movable cavity 241 is various. In the embodiment, referring to Figures 1 to 3 The driving device comprises a hydraulic pipeline 220, and the float 250 has a hydraulic cavity. The hydraulic pipeline 220 is in communication with the hydraulic cavity. Specifically, one end of the float 250 abuts against the top rod 230, and the other end of the float 250 has an opening in liquid communication with the hydraulic pipeline 220. In this way, by increasing the pressure of the liquid in the hydraulic pipeline 220, the float 250 can be driven to move towards the side close to the rotating shaft 123, so as to push the top rod 230 to move relative to the wedge-shaped slope 133, so as to drive the first clamping part 121 and the second clamping part 122 to realize the clamping action.

[0036] In the embodiment, referring to Figure 3The first driving arm 131 and the second driving arm 132 are each provided with a wedge-shaped slope 133, and the two wedge-shaped slopes 133 are oppositely arranged. Correspondingly, the top rod 230 is provided with an abutting slope 231, which is used for cooperating with the wedge-shaped slope 133. The axis of the top rod 230 is located on the central plane of the two wedge-shaped slopes 133. The pontoon 250 is driven to move by the top rod 230, so that the abutting slope 231 and the wedge-shaped slope 133 are relatively displaced, thereby driving the first clamping part 121 and the second clamping part 122 to rotate around the rotating shaft 123.

[0037] In some embodiments of the present application, the pontoon 250 is enclosed by a pressure-resistant material. In this way, the deformation of the pontoon 250 caused by the increase of the liquid pressure in the pontoon 250 can be avoided, and the sliding of the pontoon 250 in the movable cavity 241 can be facilitated, thereby ensuring the clamping or loosening of the clamping head 120. As an example, the pontoon 250 can be made of stainless steel.

[0038] In some embodiments of the present application, referring to Figure 3 , an oil seal ring 260 is arranged on the outer periphery of the pontoon 250, and the oil seal ring 260 is located between the outer periphery of the pontoon 250 and the inner wall of the movable cavity 241, so as to improve the sealing performance between the pontoon 250 and the movable cavity 241.

[0039] In some embodiments of the present application, the clamping tool comprises a reset device, which is used for driving the first clamping part 121 and the second clamping part 122 to separate. It should be understood that the specific structure and installation position of the reset device are various, and the purpose is to drive the first clamping part 121 and the second clamping part 122 to separate after clamping. For example, the reset device can be a spring arranged between the first clamping part 121 and the second clamping part 122. When clamping, the spring is compressed, and after clamping, the first clamping part 121 and the second clamping part 122 are separated under the action of the spring.

[0040] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the control switch 300 is arranged on the handle 110. In this way, the operator can control the clamping head 120 through the control switch 300 while holding the handle 110, which avoids the hand from leaving the handle 110, and facilitates the operator to control the action of the clamping head 120.

[0041] In a possible implementation, the control switch 300 is a wireless switch, and the wireless switch is in communication connection with the driving device. In this way, the wire harness connected between the handle 110 and the driving device can be reduced, which facilitates to reduce the weight of the handle 110, thereby facilitating the operator to operate.

[0042] The wireless switch has a transmitter, and the drive unit has a receiver. The wireless switch controls the drive unit to work by sending a signal to the receiver, thereby controlling the clamping head 120 to clamp or loosen.

[0043] In some embodiments of this application, the handle 110 is made of lightweight metal. Lightweight metal has a low density and a small mass for the same volume, which helps reduce the weight of the handle 110, thus making it easier for the operator to operate the handle 110.

[0044] For example, the handle 110 is made of aluminum alloy. Aluminum alloy has a low density, which can effectively reduce the overall weight of the handle 110 and make it easier for the operator to operate the handle 110.

[0045] In some embodiments of this application, the handle 110 is provided with a hand grip portion, which has a rough surface. This increases the coefficient of friction of the hand grip portion, thereby increasing friction when the operator grips the handle 110.

[0046] In one possible implementation, the handle is provided with knurling, which can increase the friction with the operator's hand, making it easier for the operator to firmly grip the handle 110.

[0047] In other embodiments, the operating surface can be a frosted surface, a raised surface, or a rough structure of other shapes.

[0048] In some embodiments of this application, the driving device includes a hydraulic pump 210, which is in liquid communication with the float 250 via a hydraulic pipe 220. The hydraulic pump 210 can change the liquid pressure within the hydraulic pipe 220, thereby controlling the clamping head 120 to clamp or loosen. For example, pressurizing the liquid within the hydraulic pipe 220 by the hydraulic pump 210 can cause the clamping head 120 to clamp; reducing the liquid pressure within the hydraulic pipe 220 by the hydraulic pump 210 can cause the clamping head 120 to loosen.

[0049] In some embodiments of this application, see Figure 3 As shown, the clamping fixture includes an adapter cap 272, a protective nut 271, and a rubber ring 273. The adapter cap 272 is used to connect the guide rod 240 and the hydraulic pipeline 220. The protective nut 271 is sleeved on the outer periphery of the adapter cap 272. The rubber ring 273 is located between the hydraulic pipeline 220 and the adapter cap 272 to improve the sealing performance between the hydraulic pipeline 220 and the adapter cap 272.

[0050] See Figures 1 to 3 As shown, the purpose of this embodiment is to improve the ease of operation for personnel, and to reduce the high requirements for the coordination of personnel's eyes, hands and feet and the manpower input required for clamping and sealing operations through a more reasonable structural design.

[0051] The clamping tool includes a clamping body, a driving device and a control switch 300, the clamping body includes an aluminum alloy handle 110, a hydraulic pipeline 220, a guide rod 240, a top rod 230, a buoy 250 made of stainless steel and a hydraulic pump 210, and the control switch 300 is a wireless switch.

[0052] The hydraulic pump 210 is controlled to start and stop by the wireless switch, and the clamping head 120 is driven by the hydraulic pipeline 220 and the buoy 250 to realize the clamping action; the handle 110 has a shell made of aluminum alloy, and the surface of the shell is provided with knurling, facilitating hand holding.

[0053] In the embodiment, the personnel operation convenience can be improved, the buoy 250 is made of stainless steel, and the shell of the handle 110 is made of aluminum alloy, so that the buoy 250 can meet the high safety performance requirement of high pressure resistance while reducing the weight of the clamping tool body.

[0054] Further, the clamping tool meets the single-hand operation by adopting the wireless switch design, and the clamping action can be completed independently by a single person, thereby reducing the personnel operation risk and production operation cost.
