In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1-3, the present invention provides a structure of a fixed knife support and a spring of a knife head of a novel electric scissors head, the structure of the fixed knife support and the spring of the knife head of the novel electric scissors head comprises:

the cutter head comprises a cutter head 10, wherein a fixed cutter support 60 is arranged on the cutter head 10, the front end of the fixed cutter support 60 is connected with a cutter head spring 50, the bottom surface of the fixed cutter support is connected with a fixed blade 20, one end of the cutter head spring 50 is connected with a movable cutter frame 40, the bottom surface of the movable cutter frame 40 is buckled with a movable blade 30, the movable blade 30 presses the fixed blade 20, the fixed blade 20 is locked with the fixed cutter support 60 through a fastener 70 to form the complete cutter head 10, the fixed cutter support 60 is provided with a spring hole 61 and a machine meter hole 62, the spring hole 61 penetrates through and intersects with the machine meter hole 62, one end of the cutter head spring 50 penetrates through the spring hole 61 and directly reaches the machine meter hole 62, and the locking is achieved through a machine meter screw 71.

Further, the movable knife rest 40 is connected with an external driving device, and further drives the movable knife 30 to move on the fixed knife 20, the movable knife 30 can move on the fixed knife 20, so that the teeth of the fixed knife and the teeth of the movable knife form cross shearing to generate shearing force, objects such as hair between the teeth are sheared, and the movable knife rest 40 is connected with the external driving device to further drive the movable knife 30 to move on the fixed knife 20. At this time, the moving blade 30 generates an upward acting force due to the resistance of the object, and one end of the blade spring 50 passes through the spring hole 61 and reaches the machine meter hole 62, and is adjusted and locked by the machine meter screw 71, so that the blade spring far away from one end of the moving blade is fixed on the fixed blade bracket 60 and continuously generates a corresponding elastic restoring force, at this time, the spring cross arm 52 is completely or partially embedded into the sliding groove 41, the moving track of the moving blade 20 slides along the spring cross arm 52, and the elastic restoring force reaches the spring cross arm 52 through the spring arm 51 and acts on the moving blade 30, and the moving blade 30 is pressed on the fixed blade 20 to reciprocate. When the tool bit works, friction between the spring cross arm 52 and the sliding groove 41 can generate high temperature, so that an oil storage groove 411 is formed in the sliding groove 41, lubricating oil can be added before the tool bit works, and the lubricating oil flows out during vibration to achieve the effect of moistening the spring cross arm 52, so that the service life of the tool bit spring is prolonged.

In some embodiments, the stationary blade holder 60 is provided with fastening holes 63 for fastening the stationary blade 20 by means of fasteners 70.

In some embodiments, the bit spring 50 has a rectangular or circular shape, and the bit spring 50 has straight spring arms 51 at two ends, the straight spring arms 51 extend out of a cross spring arm 52, and the cross spring arm 52 is completely or partially embedded in the sliding groove 41.

Further, the blade head spring 50 is integrally formed in a rectangular shape, the cross section of the blade head spring 50 may be circular or rectangular, the spring cross arm 52 needs to be linear, in order to better play a role of pressing the movable blade 30 to the fixed blade 20, the length of the spring arms 51 at the two ends of the blade head spring is consistent, the stress is equal, the swing amplitude is parallel, one end of each spring arm 51 is locked on the fixed blade bracket 60 through a machine rice screw 72 and can be adjusted, and the blade head spring has a certain elastic restoring force, when the blade head works, the movable blade 30 reciprocates along the spring cross arm 52 on the fixed blade 20, so that the cutter teeth of the fixed blade form a cross shearing action, when objects such as hair and the like exist between the cutter teeth, the cutter teeth of the movable blade are subjected to the resistance of the objects in the movement process, so that the movable blade 30 is lifted upwards, the spring 50 is influenced by the acting force of the movable blade 30 to generate the corresponding elastic restoring force to offset the acting on the movable blade 30, and under the elastic restoring force, the movable blade 30 is pressed downwards, so that the movable blade 30 can only do parallel reciprocating motion along the spring cross arm 52 and cannot move towards other directions.

In some embodiments, the movable blade holder 40 is provided with a latch 42, which is matched with the movable blade hole 32, and the movable blade groove 31 just can accommodate the movable blade holder 40.

Further, the movable blade holder 40 is provided with a plurality of clamping blocks 42, and the clamping blocks are matched with the movable blade holes 32, and the movable blade 30 is provided with a movable blade groove 31 which is just large enough to accommodate the movable blade holder 40, so that the movable blade holder 40 clamps the movable blade 30.

In some embodiments, the fixed blade 20 is provided with a fixed blade hole 21, and the fixed blade hole 21 is matched with the fastening hole 63 of the fixed blade bracket.

The working principle is as follows: when the cutter head 10 is operated, the external driving device drives the movable cutter frame 40 to move, the movable cutter frame 40 drives the movable cutter blade 30 to reciprocate along the spring cross arm 52, so that the teeth of the movable cutter blade form staggered shearing motion to generate shearing force, thereby shearing objects such as hair and the like positioned in the fixed cutter blade, in the shearing process, the movable cutter blade 30 is subjected to the resistance of the objects to generate upward acting force to act on the cutter head spring 50, at the moment, because the spring hole 61 penetrates through and intersects with the machine rice hole 62, the spring arms 51 arranged at the two ends of the cutter head spring 50 penetrate through the spring hole 61 to reach the machine rice hole 62, the spring arms are locked and can be adjusted through the machine rice screws 71, the length of the spring arms 51 at the two ends of the cutter head spring is consistent, the stress is equal, the parallel swing amplitude is realized, the cutter head spring 50 generates corresponding elastic restoring force, the movable cutter blade 30 is tightly pressed to the fixed cutter blade 20, and the movable cutter blade 30 can only move along the spring cross arm 52, therefore, the movable blade 30 can do parallel reciprocating motion relative to the fixed blade 20, and meanwhile, due to the structural design of the fixed blade 20, the acting force generated when the movable blade 30 moves and pressing the fixed blade 20 can be counteracted, so that the working stability of the cutter head 10 is ensured, and the hair cutting effect of the cutter head is ensured.
