[0010] A method for using a portable back massager based on health care includes the following steps: S1. Fix the device to the back of the human body through the waist belt and shoulder straps, so that the sponge pad fits the back of the human body; S2, after the power is turned on, the connecting rod is moved inside the movable cavity through the transmission block, and at the same time, the connecting rod drives the movable block to move and hammer the hammering device inside the equipment through the push-pull rod; S3. Then, during the movement of the beating device, the gear and the gear rod interact with each other so that the beating device can rotate and beat.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The transmission block drives the connecting rod to move inward through the clamping block, and the connecting rod enables the push-pull rod to push the lever to move outward on both sides, and the lever drives the movable block to slide inside the first movable groove, and the movable block drives the beating device to move inside the movable cavity, so that the beating device moves and beats the back of the human body, preventing the device from beating one place for a long time, thereby increasing the range of the device beating the back of the human body, and at the same time improving the uniformity of the beating of the back of the human body, and improving the comfort of the device when beating; 2. After the beating device is powered on, the beating work is carried out. Because the sponge pad is in contact with the back of the human body, the beating of the beating device acts on the sponge pad. The sponge pad buffers the impact force of the beating groove of the beating device, thereby improving the comfort of the beating device when beating the back of the human body, and reducing the damage to the back of the human body caused by the greater impact force; 3. In the process of driving the movable block to move by the lever, because the gear and the gear rod are meshed with each other, the gear rotates through the gear rod during the movement of the movable block, and then the movable block drives the beating device to rotate, which effectively realizes the rotational beating of the human back and improves the practicability of the device for beating the human back; 4. The guide block drives the transmission block to move toward the middle of the transmission groove and makes the extrusion plate abut against the power tooth. Under the action of the power tooth, the extrusion plate moves inward and compresses the second spring. At the same time, the extrusion plate drives the movable rod to move inside the second movable groove. The movable rod moves to both sides inside the clamping block in the movable opening, so that the clamping block cannot clamp the connecting rod, and the connecting rod stops moving. At this time, when the transmission block continues to move and drives the extrusion plate to be unable to abut against the power tooth, the extrusion plate moves outward under the action of the second spring and drives the clamping block to clamp the connecting rod through the movable rod. The connecting rod is driven outward by the movement of the transmission block, thereby realizing the reciprocating continuous movement of the equipment, effectively making the equipment move in an offset manner, and improving the linkage of the equipment operation; 5. Wear the device on your shoulders with the shoulder strap so that the sponge pad contacts the back of the human body. At the same time, wrap the belt around the waist of the human body. At this time, connect the buckle and the block to each other, so that the device can be carried on the back of the human body to prevent the device from falling during the hammering process, thereby improving the device's relief of fatigue.

Example

[0024] A method for using a portable back massager based on health care includes the following steps: S1, fix the device on the back of the human body through the waist belt 2 and the shoulder strap 5, so that the sponge pad 6 fits the back of the human body; S2, after the power is turned on, the connecting rod 18 is moved inside the movable chamber 7 through the transmission block 26, and at the same time, the connecting rod 18 drives the movable block 13 to drive the beating device 15 to move and beat inside the device through the push-pull rod 17; S3.

The second spring 29 stretches so that the extrusion plate 30 and the inner wall of the transmission groove 19 abut against each other, and the extrusion plate 30 clamps the connecting rod 18 through the movable rod 31.

[0026] Wear the shoulder strap 5 on the shoulder so that the sponge pad 6 contacts the back of the human body, and at the same time, wrap the belt 2 around the waist of the human body. At this time, the buckle 3 and the block 4 are mutually engaged, so that the device can be carried on the back of the human body to prevent the device from falling during the hammering process, thereby improving the device's relief of human fatigue, and connecting the power supply to power the device.

[0027] At the same time, because the beating device 15 is electrically connected to the equipment using a power supply, the beating device 15 performs the beating work after being energized, because the sponge pad 6 is in contact with the back of the human body, and then the beating of the beating device 15 acts on the sponge pad 6, and the sponge pad 6 buffers the impact force of the beating device 15 beating the groove, thereby improving the comfort of the beating device 15 beating the back of the human body. At the same time, because the power tooth 21 is externally connected to a driving device, and then the power tooth 21 is driven to rotate inside the transmission groove 19 after the driving device is energized, and at the same time, because the power tooth 21 is meshed with the chain 23, and then the chain 23 is driven by the power tooth 21 to transmit on the outside of the transmission tooth 22, the chain 23 drives the guide block 24 to move inside the transmission groove 19, the guide block 24 drives the transmission block 26 to slide on the slide bar 25 through the guide groove 27, and the transmission block 26 drives the connecting rod 18 to move inward through the clamping block 33, and the connecting rod 18 causes the push-pull rod 17 to push to both sides The movable lever 11 moves outward, and the lever 11 drives the movable block 13 to slide inside the first movable groove 9, and the movable block 13 drives the beating device 15 to move inside the movable cavity 7, so that the beating device 15 moves and beats the back of the human body, preventing the device from beating one place for a long time, thereby increasing the range of the device beating the back of the human body, and at the same time improving the uniformity of the beating of the back of the human body, and improving the comfort of the device when beating, and at the same time under the action of the first spring 12, the movable block 13 can stably move inside the first movable groove 9, at the same time, in the process of the movable block 13 driven by the lever 11 to move, because the gear 14 and the gear rod 16 are meshed with each other, and then in the movement process of the movable block 13, the gear 14 rotates through the gear rod 16, and then the movable block 13 drives the beating device 15 to rotate, effectively realizing the rotational beating of the back of the human body, and improving the practicability of the device beating the back of the human body.

[0028] During the continuous transmission process of the chain 23, the transmission block 26 is driven by the guide block 24 to move toward the middle of the transmission groove 19 and make the extrusion plate 30 abut against the power tooth 21. Under the action of the power tooth 21, the extrusion plate 30 moves inward and compresses the second spring 29. At the same time, the extrusion plate 30 drives the movable rod 31 to move inside the second movable groove 28. The movable rod 31 moves to both sides inside the clamping block 33 in the movable opening 32, so that the clamping block 33 cannot clamp the connecting rod 18, and the connecting rod 18 stops moving. At this time, when the transmission block 26 continues to move and drives the extrusion plate 30 to be unable to abut against the power tooth 21, the extrusion plate 30 moves outward under the action of the second spring 29 and drives the clamping block 33 to clamp the connecting rod 18 through the movable rod 31. The connecting rod 18 is driven to move outward by the movement of the transmission block 26, thereby realizing the reciprocating continuous motion of the equipment, effectively making the equipment move in an offset manner, and improving the linkage of the equipment operation.
