Specifically, since the driving device 2 includes two mechanisms, i.e., the power mechanism 21 and the transmission mechanism 22, the operating platform 1 needs to provide a large space for installation and operation, and the lower area of the operating platform 1 has a large movement space, the power mechanism 21 and the transmission mechanism 22 need to be disposed on the bottom surface of the operating platform 1, so that the operating platform 1 can provide a large movement space to ensure the normal operation of the power mechanism 21 and the transmission mechanism 22, and the space utilization rate of the operating platform 1 can be improved.

Specifically for the present embodiment, the motor 211 may be fixed on the motor base 14 by a vibration-proof pad bolt, and a space gap is maintained between the motor 211 and the operation surface 11. The motor 211 is installed by arranging the motor base 14, so that the installation of the motor 211 is firmer and more stable, and further, a larger space gap is formed between the motor 211 and the operation surface 11, so that the influence of the vibration generated in the operation process of the motor 211 transmitted to the operation surface 11 on the operation of the driving device 2 can be reduced.

In some embodiments, referring to fig. 2, 4 and 5, the transmission mechanism 22 may include, but is not limited to, a belt transmission, a gear transmission, a linkage mechanism, etc. For example, the transmission mechanism 22 of the present application may be a link mechanism, and specifically, the transmission mechanism 22 includes a first link 221 and a second link 222, the first link 221 has a first movable end 221a and a second movable end 221b, and the second link 222 has a third movable end 222a and a fourth movable end 222b; the first movable end 221a is rotatably connected to the third movable end 222a, the second movable end 221b is connected to the output shaft 211a, and the fourth movable end 222b is connected to the second blade member 32.

By additionally arranging the third connecting rod 223, a larger supporting force can be applied to the second blade member 32 on the basis that the second connecting rod 222 supports the second blade member 32, so that the second blade member 32 is prevented from bending and deforming due to the overlarge self gravity, and the stability of the transmission mechanism 22 can be improved.

Further, the transmission mechanism 22 may further include a fourth link 224, the fourth link 224 includes a first end 224a and a second end 224b, the second movable end 221b is rotatably connected to the first end 224a, the first end 224a is connected to the output shaft 211a, the sixth movable end 223b is rotatably connected to the second end 224b, and the second end 224b is fixedly connected to the operation platform 1. It will be appreciated that the first end 224a is fixedly connected to the output shaft 211a and the second end 224b is fixedly connected to the console 1 such that the fourth link 224 does not rotate. The non-rotating fourth link 224 applies a continuous acting force to the first link 221 and the third link 223, the acting force can be divided into a supporting force in the vertical direction and a pulling force in the horizontal direction, when the second blade member 32 applies a downward pressure to the first link 221, the second link 222 and the third link 223, the supporting force in the vertical direction can counteract the pressure, so as to reduce the load bearing of the first link 221 and the third link 223, and the pulling force in the horizontal direction can pull the first link 221 and the third link 223, so as to reduce the slipping phenomenon of the second movable end 221b and the sixth movable end 223 b.

It can be understood that the addition of the connecting member 13 to the housing hole 12 enables the first blade member 31 and the second blade member 32 having a large weight to be stably attached to the console 1 without dropping. The operation surface 11 is the upper surface of the operation table 1, and the first blade member 31 and the second blade member 32 are at least partially arranged in the accommodating hole 12 by forming the accommodating hole 12 on the operation surface 11, so that the arrangement space of the operation surface 11 can be saved, and the operation of the shear spring is prevented from being influenced by the arrangement of too many mechanisms on the operation surface 11.

In some embodiments, referring to fig. 6, the first blade member 31 includes a first fixing portion 31a and a first blade portion 31b detachably connected to the first fixing portion 31a, and the second blade member 32 includes a second fixing portion 32a and a second blade portion 32b detachably connected to the second fixing portion 32 a; the first fixing portion 31a is at least partially located in the receiving hole 12 and fixedly connected with the connecting member 13, and the second fixing portion 32a is at least partially located in the receiving hole 12 and movably connected with the connecting member 13. The first blade part 31b of the first blade member 31 and the second blade part 32b of the second blade member 32 are both detachably designed, which facilitates blade replacement. Because the spring has certain hardness, when using a cutting edge portion to cut the spring many times, the phenomenon such as cutting edge wearing and tearing appears easily, consequently in order to guarantee to cut efficiency, need regularly change cutting edge portion.

Further, the first blade portion 31b and the second blade portion 32b are block-shaped blades, only the edges of the first blade portion 31b and the second blade portion 32b which are close to each other for shearing the spring are set to be relatively sharp blades, and the use safety of the shearing device 100 can be improved.

In some embodiments, referring to fig. 4, the operation surface 11 is further provided with a control button 15, the control button 15 is electrically coupled to the power mechanism 21, and the control button 15 is used for controlling the power mechanism 21 to open or close. By arranging the control key 15 on the operation surface 11, an operator presses the control key 15 to enable the shearing device 100 to be in an opening state, the control key 15 transmits an electric signal to the power mechanism 21 to control the power mechanism 21 to operate, so that the transmission mechanism 22 is driven to move, and the shearing device 3 shears the spring; when the control button 15 is pressed again to make the cutting device 100 in the closed state, the control button 15 stops transmitting the electric signal to the power mechanism 21, the power mechanism 21 stops operating, the transmission mechanism 22 stops operating, and the cutting device 3 stops cutting the spring. The additional control key 15 controls the driving device 2 to control the working state of the shearing device 3 at any time, and can cut off the power supply when the shearing spring of the shearing device 3 is abnormal in time, so that the safety of the shearing equipment 100 is improved.

Specifically, as can be seen from the foregoing description, when the transmission mechanism 22 is a four-bar mechanism, that is, when the transmission mechanism 22 adopts a mode of simultaneously providing the first link 221, the second link 222, the third link 223 and the fourth link 224, the principle of the shear spring of the shearing apparatus 100 provided in the embodiment of the present application can be further described in detail as follows:

referring to fig. 2, 4 and 5, when the control button 15 is pressed, the motor 211 starts to operate, the output shaft 211a of the motor 211 rotates in the counterclockwise direction, the output shaft 211a drives the first link 221 to rotate in the counterclockwise direction, the first link 221 further drives the second link 222 to rotate in the clockwise direction, so that the second link 222 drives the third link 223 to rotate in the counterclockwise direction, and simultaneously, the heights of the fourth movable end 222b of the second link 222 and the fifth movable end 223a of the third link 223 are raised and move in the direction of the first blade member 31, so that the height of the second blade member 32 is raised and moves toward the first blade member 31, and when a spring is placed in a shearing space formed by the first blade member 31 and the second blade member 32, the second blade member which is continuously close to the shearing space can reduce the size of the shearing space, thereby completing automatic shearing of the spring.
