[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: A power adapter, see Figures 1 to 4 The adapter body 1 includes a power connection cable 2 at one end and a device connection cable 3 at the other end. It also includes two plugs 7 and a U-shaped frame 4. Two plugs 7 are fixed to the upper and lower ends of the adapter body 1's outer shell, respectively. The upper and lower walls of the U-shaped frame 4 have slots 401 that engage with the two plugs 7. The top of the U-shaped frame 4 is positioned with one of the plugs 7 via a positioning structure 6. This invention, by using the plugs 7, U-shaped frame 4, and slots 401, has the advantage of positioning the adapter body 1 on the outer shell of the medical device, thus lifting the adapter body 1 off the ground and protecting it from being kicked. It also solves the problem that the adapter is not fixed and is easily kicked by passersby, causing displacement and pulling on the connection cable.

[0029] Specifically, a connecting plate 5 is fixed in the middle of the back end of the U-shaped frame 4. The connecting plate 5 is fixed to the outer shell of the medical device by screws, thereby setting the U-shaped frame 4 and the positioning adapter body 1 on the outer shell of the medical device and positioning them off the ground.

[0030] Furthermore, rubber pads 702 are fixed at both ends of the insert 7, with the outer side of the rubber pads 702 contacting and engaging with the inner wall of the slot 401. By providing the rubber pads 702, this invention increases friction when the insert 7 is inserted into the slot 401, ensuring stability of the insert 7 after insertion and facilitating positioning of a single insert 7.

[0031] Furthermore, the positioning structure 6 includes a positioning block 601 and a horizontal block 602; the positioning block 601 passes through the through hole 402 opened in the horizontal section at the top of the U-shaped frame 4; wherein, the inner end of the positioning block 601 is inserted into and cooperates with the insertion hole 701 opened on the top side of an insertion block 7; the horizontal block 602 is fixedly mounted on the top of the positioning block 601. By setting the positioning block 601 and the horizontal block 602, this utility model has the advantage of positioning an insertion block 7 in the insertion slot 401, so that the adapter body 1 remains stable after being embedded in the U-shaped frame 4.

[0032] It is worth noting that two springs 603 are symmetrically arranged between the bottom ends of the horizontal block 602 and the top side of the horizontal section of the U-shaped frame 4. The two ends of each spring 603 are fixedly connected to the bottom ends of the horizontal block 602 and the top side of the horizontal section of the U-shaped frame 4, respectively. The elastic coefficient of the springs 603 can be selected and used by those skilled in the art based on the actual situation. This invention, by setting the springs 603, has the advantage of automatically pulling down the positioning block 601 and the horizontal block 602 after they have been pulled upwards, facilitating the positioning of one insertion block 7.

[0033] It is worth noting that all four sides of the horizontal block 602 extend beyond the top and bottom edges of the positioning block 601, providing a force point for the operator to lift the horizontal block 602 by hand, making it easier to pull the horizontal block 602.

[0034] Working principle: Using the device of this utility model, the connecting plate 5 is fixed to the outer shell of the medical device with screws. The adapter body 1 is inserted into the U-shaped frame 4, and the two plugs 7 are inserted into the two slots 401 respectively. At the same time, the horizontal block 602 is moved upward, and the positioning block 601 moves upward accordingly until the inner end of the positioning block 601 enters the through hole 402. The spring 603 is stretched. When the plug 7 is fully inserted into the slot 401, the outer side of the rubber pad 702 contacts the inner side wall of the slot 401 to increase the friction and keep the plug 7 stable after it is inserted into the slot 401. The horizontal block 602 is released, and under the action of the spring 603, the positioning block 601 moves downward along the through hole 402 until the inner end of the positioning block 601 is inserted into the plug hole 701 to position one plug 7, thereby positioning the adapter body 1 in the U-shaped frame 4. The power connection cable 2 is connected to the power supply, and the device connection cable 3 is connected to the medical device.
