Referring to fig. 1 to 5, in an embodiment of the present invention, a portable electric clamping and pressing clamp includes a clamp handle 2 and a clamp portion 1, wherein the clamp portion 1 includes a housing 11, and a through hole 12 is formed in a middle portion of the housing 11; a rotating ring 13 is arranged in the shell 11, and the rotating ring 13 and the through hole 12 are coaxial; the rotating ring 13 is connected with a pressing block 14 through an arc-shaped groove 132 in a sliding manner; a driving mechanism 21 is arranged in the handle portion 2 and used for driving the rotation ring 13 to operate.

It should be noted that the rotating ring 13 is rotatably installed in the housing 11, specifically, an arc-shaped snap ring 18 is disposed on the inner side of the housing 11, a snap groove 19 is disposed on the rotating ring 13 corresponding to the snap ring 18, and the snap ring 18 and the snap groove 19 are engaged with each other, so that the rotating ring 13 can be installed in the housing 11 and the rotating ring 13 can freely rotate. The through hole 12 in the middle of the rotating ring 13 is used for facilitating the insertion and removal of the pipe to perform the pipe clamping operation. The end of the rotating ring 13 is connected with the pressing block 14 through the arc-shaped groove 132, when the rotating ring 13 rotates, the degree of freedom of the pressing block 14 in the tangential direction of the rotating ring 13 is limited, so that the pressing block 14 is forced to move along the arc-shaped groove 132, the pressing block 14 gradually moves towards the center of the inner side of the through hole 12, and the purpose of clamping and pressing the pipe fitting is achieved; the clamping and pressing mode is progressive, the clamping and pressing of the pipe fitting are more uniform, and meanwhile, local indentations cannot be generated, so that the pipe fitting is more attractive; and in the aspect of practicality, because this card presses the structure progressive, can be applicable to the card of more pipe fittings of different size diameters and press work, consequently the suitability is also stronger.

The top and bottom surfaces of the rotating ring 13 are provided with arc-shaped grooves 132.

It should be noted that, in some embodiments, the arc-shaped grooves 132 may be disposed on both end surfaces of the top surface and the bottom surface of the rotating ring 13, so that both ends of some linear pipe fittings can be clamped and pressed simultaneously, and the use is more convenient and faster.

Three arc-shaped grooves 132 are formed in one surface of the rotating ring 13, and three or six pressing blocks 14 are arranged; the inner side of the pressing block 14 is an arc-shaped pressing surface.

It should be noted that, in some embodiments, the arc-shaped grooves 132 on a single end surface of the rotating ring 13 are uniformly provided in three numbers, and the three arc-shaped grooves 132 can ensure that the pressing block 14 has a longer movable length, improve the size range of the pipe fitting capable of being clamped and pressed, and ensure the clamping and pressing effect and fully utilize the space on the end surface of the rotating ring 13.

It should also be noted that in some embodiments, the inner side surface of the pressing block 14 can be replaced by a cutting module with cutting edges according to actual use requirements.

The driving mechanism 21 includes a power source 211; the output end of the power source 211 is connected with a transmission assembly 212, and the other end of the transmission assembly 212 is provided with a rack 213.

It should be noted that in some embodiments, the output end of the power source 211 drives the rack 213 to reciprocate, and the rack 213 corresponds to the latch 131 outside the rotating ring 13; the rack 213 drives the rotation of the rotating ring 13 under the action of the power source 211, so that the pressing block 14 moves to realize the clamping and releasing actions on the pipe.

The power source 211 is a low speed motor.

It should be noted that, the low-speed motor can provide bigger thrust, is more suitable for the card of pipe fitting to press the work.

The pressing block 14 is provided with a shifting block 141 for presetting the position of the pressing block 14 according to the diameter of the pipe fitting.

It should be noted that the tail portion of the end face of the pressing block 14 is further provided with a shifting block 141, and before clamping and pressing the pipe fitting, the shifting block 141 can be shifted according to the diameter of the pipe fitting to be clamped and pressed, so that the inner side face of the pressing block 14 is attached to the outer surface of the pipe fitting to be clamped and pressed in advance, and the subsequent pipe fitting clamping and pressing work can be completed quickly.

The compression block 14 is detachably connected with the rotating ring 13; a sealing limit cover 15 is fixed on the housing 11, an adjusting groove 151 is arranged on the sealing limit cover 15 corresponding to the shifting block 141, and a limit stop 152 is arranged on the inner side of the sealing limit cover 15 corresponding to the pressing block 14.

It should be noted that the pressing block 14 is detachable from the rotating ring 13, the pressing block 14 may be installed on a single end surface of the rotating ring 13, or the pressing blocks 14 may be installed on both end surfaces of the rotating ring 13; meanwhile, in the actual use process, the pressing block 14 modules with different radians or shapes can be replaced according to requirements, so that different use requirements can be met.

The tail of the handle 2 is also provided with a power source 22, an electric wire 23 and a control chip 24.

It should be noted that, in some embodiments, the power supply 22 disposed in the handle portion 2 is used for providing energy to each component in the clamping and pressing pliers, so as to facilitate carrying and use; the wire 23 is used for charging the power supply 22 on one hand, and directly providing energy for the card pressing clamp to drive each component in the card pressing clamp to operate on the other hand; the control chip 24 is used for controlling the operation of each component in the crimping pliers.

The clamping part 1 is further provided with a heating device 16 and a sensor 17.

It should be noted that in some embodiments, a heating device 16 is further disposed on the clamp portion 1 to meet some requirements in practical use; and the sensor 17 is used for monitoring the working state of the card pressing clamp and feeding back the working state to the control chip 24.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
