Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1, an embodiment of the present invention includes:
high cutting force electric shears comprising: casing 1, 1 inside group battery 2 and with the motor 3 that 2 electrical property of group battery links to each other of casing, just 1 right side of casing is provided with shears the mechanism, its characterized in that, it includes to shear the mechanism: the transmission shaft 4 is connected with the motor 3, the fixed blade 8 is fixed on the shell 1, and the movable blade 7 is hinged with the fixed blade 8;
the left side end of the movable blade 7 is provided with a sliding groove 9, the right side end of the transmission shaft 4 is provided with a gear set 5, the center of the gear set 5 is fixedly provided with a connecting rod 6, and the connecting rod 6 is inserted into the sliding groove 9 through a movable pin 10.
Further, the gear set 5 is formed by meshing a small bevel gear and a large bevel gear, and the meshing of the teeth of the small bevel gear and the large bevel gear is used for transmitting the rotating force of the transmission shaft 4 to the connecting rod 6, so that the connecting rod 6 is driven to do circular motion around the joint of the gear set 5 and the connecting rod 6, the gear set 5 can be opened and closed once, the gear set 5 does not need to be stopped urgently and reversed to make the reverse motion, and the control of the motor 3 simpler.
Further, the shearing mechanism further comprises a hall plate 11 fixedly installed in the casing 1, an upper position sensor 12 is installed at the upper end of the hall plate 11, a lower position sensor 13 is installed at the lower end of the hall plate 11, and both the upper position sensor 12 and the lower position sensor 13 are hall sensors.
Further, a magnet 15 is fixedly installed in the center of the left end of the movable blade 7, and the magnet 15 swings between the upper position sensor 12 and the lower position sensor 13 along the hall plate 11; when the upper position sensor 12 senses the magnet 15 on the left end of the movable blade 7, the movable blade 7 and the fixed blade 8 are in the optimal closed state, and when the lower position sensor 13 senses the magnet 15 on the left end of the fixed blade 8, the movable blade 7 and the fixed blade 8 are in the maximum open state.
Further, the upper position sensor 12 and the lower position sensor 13 are connected to a hall switch 14 through a hall plate signal line 16, the hall switch 14 is electrically connected to the motor 3, and when the upper position sensor 12 and the lower position sensor 13 sense the magnet 15, a signal is sent to the hall switch 14 through the hall plate signal line 16, so that the opening and closing of the motor 3 is controlled through the hall switch 14.
The utility model discloses a high cutting force electric scissors, its specific theory of use as follows:
firstly, an operator quickly double-clicks the hall switch 14 to activate the motor 3 to operate, so that the transmission shaft 4 is driven to rotate, the transmission shaft 4 drives the connecting rod 6 to rotate under the action of the gear set 5, the connecting rod 6 is inserted into the sliding groove 9 through the movable pin 10, so that the connecting rod 6 drives the movable blade 7 to swing while rotating, at the moment, the connecting rod 6 moves in the sliding groove 9, so that the driving force arm of the connecting rod is gradually increased, the middle position of the connecting rod reaches the maximum value, and finally the movable blade 7 and the fixed blade 8 are closed and opened.
It should be explained that, in the process of swinging the movable blade 7, the magnet 15 at the left end of the movable blade 7 also swings, when the magnet 15 swings to the upper position sensor 12 on the hall plate 11, the upper position sensor 12 senses a signal and sends a disconnection signal to the hall switch 14 through the hall plate signal line 16, and the hall switch 14 controls the motor 3 to lose power and stop running, so that the movable blade 7 stops swinging, the movable blade 7 and the fixed blade 8 can be kept in an optimal closed state, the shearing force is finally kept, and after the shearing is completed, the operator can quickly continue to use the double-machine hall switch 14; when the magnet 15 swings to the lower position sensor 13, the lower position sensor 13 senses a signal and sends a disconnection signal to the hall switch 14 through the hall plate signal line 16, and the hall switch 14 stops running when the motor 3 is controlled to be powered off, so that the movable blade 7 is guaranteed to stop swinging, the movable blade 7 and the fixed blade 8 can be kept in the maximum opening state, and the storage in the stop state is facilitated.
Be different from prior art, the utility model relates to a high cutting force electric scissors through adopt connecting rod 6 alternate in transmission structure in the spout 9 for replace current crank link mechanism, thereby can make when drive blade 7, its drive power arm increases gradually, and reaches the maximum value at the intermediate position, improves cutting ability by a wide margin.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the products of the present invention are usually placed when used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element to which the term refers must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
