[0001] The utility model relates to the technical field of motors for scissors machines, in particular to a motor for scissors machines which is convenient for speed regulation. Background Art

[0002] The scissors machine uses a battery to power the motor, which makes the motor perform reciprocating rotation and increases the torque through the planetary gear, so that the scissors of the scissors machine have a greater cutting force and can cut objects.

[0003] However, during use, since the motor speed inside the scissors machine is constant, that is, the speed of the scissors of the scissors machine in cutting objects is constant, workers cannot use the scissors machine to cut objects quickly and conveniently, which affects the efficiency of workers in daily work and cannot meet the needs of workers to use the scissors machine to cut different objects. To this end, we propose a motor for a scissors machine that is easy to adjust the speed. Utility Model Content

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Combination Figure 1-4As shown, a motor for a scissors machine that is easy to adjust speed includes a scissors machine motor body 1, and a gear box 2 and a housing 3 arranged at one end of the scissors machine motor body 1. The gear box 2 can enhance the torque of the output shaft of the scissors machine motor body 1. Since the output shaft of the scissors machine motor body 1 can perform reciprocating rotational motion, the output shaft of the gear box 2 can perform reciprocating rotational motion, thereby driving one scissor head of the scissors machine body 1 to reciprocate and cooperate with the other scissor head to shear objects. The housing 3 can be used as a carrier when the scissors machine motor body 1 and the gear box 2 work together. A gear part 4 is provided at one end of the output shaft of the scissors machine motor body 1, which can provide a change in the gear part 4 to change the output speed of the scissors machine motor body 1, thereby changing the speed at which the scissors of the scissors machine shear objects;

[0020] Among them, the gear member 4 includes a gear 1 5 meshingly connected with the gear box 2, a gear 2 6 is provided at one end of the gear 1 5 away from the gear box 2, a gear plate 7 is provided at one end of the output shaft of the scissors machine motor body 1, an internal gear 8 is provided on the surface of the gear plate 7, a round rod 9 is provided in the middle of the gear plate 7, a gear 3 10 is provided at one end of the round rod 9, the gear surface radius of the gear 3 10 is smaller than the gear surface radius of the internal gear 8, and the gear 2 6 is meshingly connected with the internal gear 8 or the gear 3 10;

[0021] When the worker starts using the scissors machine, he or she will use it to cut objects. When cutting some smaller objects, the worker can push the scissors machine motor body 1 to move, so that the inner gear 8 meshes with gear two 6, thereby increasing the output speed of the scissors machine motor body 1 and the high rate at which the scissors machine shear objects. When the worker needs to cut larger objects, the scissors machine motor body 1 is controlled to move again, and gear two 6 meshes with gear three 10, so that the output speed of the scissors machine motor body 1 is reduced, so that the worker can cut objects accurately. This is beneficial for the worker to adjust the output speed of different scissors machine motor bodies according to different cutting targets in daily work, so as to cooperate with the work just right and improve daily work efficiency.

[0022] Preferably, a gap is left between gear one 5 and gear two 6, so that when the internal gear 8 is meshed with gear two 6, gear three 10 is idle and will not be affected by other objects.

[0023] Preferably, a through groove 11 is provided on the inner wall of the scissors machine motor body 1, a spring 12 is provided on the inner wall of the through groove 11, a ball 13 is provided at one end of the spring 12, a limiting ring 14 is provided at the end of the through groove 11 close to the ball 13, and the inner diameter of the limiting ring 14 is smaller than the diameter of the ball 13. Since the ball 13 is in close contact with the limiting ring 14 in the initial state and the spring 12 is in a compressed state, when the scissors machine motor body 1 moves, the ball 13 separates from the limiting ring 14 and squeezes the spring 12 to contract. At this time, the restriction on the scissors machine motor body 1 is released, which is conducive to the movement of the ball 13 to another circular hole 18, thereby re-fixing the scissors machine motor body 1.

[0024] Preferably, the inner wall of the shell 3 is provided with a slide groove 16 and a through hole 17, and circular holes 18 are respectively provided at both ends of the surface of the slide groove 16. The inner diameter of the circular hole 18 is equal to the diameter of the ball 13, so that the scissors machine motor body 1 can move to two positions on the inner wall of the shell 3, which is beneficial for the scissors machine motor body 1 to maintain its own stability when rotating.

[0025] Preferably, a through hole 17 is provided on the inner wall of the shell 3, and the through hole 17 is located on the side away from the slide groove 16. A push rod 15 is provided on the end of the scissors machine motor body 1 away from the through groove 11, and the push rod 15 passes through the through hole 17. When the worker needs to adjust the output speed of the scissors machine motor body 1, the push rod 15 can be pushed to move in the through hole 17, so as to control the movement of the scissors machine motor body 1.

[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
