DETAILED DESCRIPTION

[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 1-4 As shown, a scissors machine motor housing that is easy to repair includes a scissors machine motor housing body 1, and a gear box 2 arranged at the end of the scissors machine motor housing body 1. The gear box 2 can be driven by the reciprocating rotation of the scissors machine motor. The helical gear at the output end of the gear box 2 performs reciprocating rotation, thereby driving one scissor head of the scissors machine to reciprocate and cooperate with the other scissor head to shear objects. The surface of the scissors machine motor housing body 1 is provided with a connecting component 3;

[0020] The connecting assembly 3 includes a ring 4 and a rotating ring 5 which are adjacently arranged on the surface of the scissors motor housing body 1. The inner wall of the ring 4 is provided with a through hole 6. A ball 7 is penetrated inside the through hole 6. A slide groove 8 is provided on the inner wall of the gear box 2. The ball 7 is used to be inserted into the slide groove 8 to generate resistance to the sliding of the gear box 2.

[0021] In actual use, when a worker encounters a malfunction in the scissors machine, the worker takes the scissors machine motor out of the scissors machine, and when troubleshooting the cause of the malfunction, rotates the rotating ring 5 on the surface of the scissors machine motor housing body 1, so that the third trapezoidal block 16 contacts the trapezoidal groove 10, thereby causing the slider 12 to move a certain distance in a directional manner on the inner wall of the ring 4. At this time, the ball 7 is separated from the slide groove 8 on the inner wall of the gear box 2, and the worker can take the gear box 2 and move it in the direction of the scissors machine motor output shaft, thereby separating the gear box 2 from the scissors machine motor housing body 1, which is beneficial for the worker to inspect the scissors machine motor and improves the worker's work efficiency in repairing the scissors machine motor.

[0022] Preferably, the inner wall of the rotating ring 5 is provided with a plurality of trapezoidal grooves 10, and the rotating ring 5 is arranged on the side of the circular ring 4 away from the gear box 2. The rotating ring 5 is used to rotate on the surface of the scissors motor housing body 1 to restrict the circular ring 4. When the trapezoidal groove 10 contacts the third trapezoidal block 16, the ball 7 is separated from the slide groove 8, and the worker can manually separate the gear box 2 from the scissors motor housing body 1. Similarly, when the trapezoidal groove 10 is separated from the third trapezoidal block 16, the gear box 2 is tightly connected to the scissors motor housing body 1.

[0023] Preferably, multiple springs 11 are provided inside the ring 4, and sliders 12 are provided at the ends of the multiple springs 11. When the third trapezoidal block 16 drives the slider 12 to move, the slider 12 will squeeze the spring 11, and under the action of the spring 11, the slider 12 drives the third trapezoidal block 16 to reciprocate on the inner wall of the ring 4.

[0024] Preferably, a positioning block 13 is provided on one side of the slider 12, a positioning groove 14 is provided on the inner wall of the ring 4, the positioning block 13 is movably arranged in the positioning groove 14, a second trapezoidal block 15 is provided on the side of the slider 12 close to the ball 7, and a third trapezoidal block 16 is provided on the end of the slider 12 away from the spring 11, the third trapezoidal block 16 is used to be inserted into the trapezoidal groove 10 to generate resistance to the rotation of the rotating ring 5, when the slider 12 moves on the inner wall of the ring 4, the positioning block 13 moves on the surface of the positioning groove 14 to limit the movement range of the slider 12 , a first trapezoidal block 18 is provided on the side of the ball 7 close to the inner wall of the ring 4, and the inclined surface of the first trapezoidal block 18 and the inclined surface of the second trapezoidal block 15 squeeze each other to push the ball 7 to move in the through hole 6. When the slider 12 moves, the slider 12 will drive the second trapezoidal block 15 and the first trapezoidal block 18 to squeeze each other, so that the first trapezoidal block 18 drives the ball 7 to move linearly inside the through hole 6, and the third trapezoidal block 16 will be squeezed by the trapezoidal groove 10, so that the third trapezoidal block 16 and the slider 12 move on the inner wall of the ring 4. The first trapezoidal block 18 and the ball 7 are restricted by the through hole 6, so they can only move along the inner wall of the through hole 6. During the movement of the second trapezoidal block 15, the inclined surface of the second trapezoidal block 15 squeezes the inclined surface of the first trapezoidal block 18, thereby driving the first trapezoidal block 18 to move linearly.

[0025] Preferably, a rectangular groove 9 is provided at the port of the gear box 2, and a rectangular rod 17 is provided on the surface of the ring 4. The rectangular rod 17 is used to be inserted into the rectangular groove 9 to realize rotation locking of the gear box 2 and the ring 4. When the ball 7 and the rectangular rod 17 are in contact with the slide groove 8 and the rectangular groove 9 respectively, the gear box 2 and the scissors motor housing body 1 are in a tightly fixed state, and the rectangular rod 17 can prevent the gear box 2 from rotating on the surface of the scissors motor housing 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.
