[0027] See also Figure 1-5 , an embodiment provided by the utility model:

[0028] A medical metering handheld metering device, comprising:

[0029] A metering device body 1 is provided with a display screen 2 on the top of the metering device body 1, a cantilever beam weighing sensor 3 is provided at the bottom of the metering device body 1, a hanging ring 4 is fixedly installed on the bottom end of the cantilever beam weighing sensor 3, a hook 5 is hung on the hanging ring 4, a hanging rope 6 is fixedly connected to the lower side of the outer wall of the hook 5, and a display plate 7 is fixedly connected to the bottom end of the hanging rope 6, and a plurality of supports 10 are fixedly installed at equal intervals on the outer wall of the metering device body 1, and the number of the supports 10 is three, and the supports 10 are rotatably connected to a multi-stage telescopic rod 8 through the damping shaft thereon.

[0030] A symmetrically distributed fixed block 14 is fixedly installed on the upper side of the outer wall of the multi-stage telescopic rod 8, a sliding rod 13 is fixedly installed between the two fixed blocks 14, a sliding block 17 is sleeved on the outer wall of the sliding rod 13, a limiting slide plate 16 is fixedly installed on the side of the sliding block 17 close to the multi-stage telescopic rod 8, and the limiting slide plate 16 is slidably connected to the outer wall of the multi-stage telescopic rod 8, a spring 15 is sleeved on one side of the sliding block 17 on the outer wall of the sliding rod 13, a positioning rod 11 is fixedly installed on the side of the sliding block 17 away from the multi-stage telescopic rod 8, a positioning groove 18 corresponding to the position and number of the positioning rod 11 is opened on the outer wall of the metering device body 1, and the positioning groove 18 is clamped with the positioning rod 11, and the limiting slide plate 16 is slidably connected to the outer wall of the multi-stage telescopic rod 8, so as to ensure the stability of the sliding of the sliding block 17 on the outer wall of the sliding block 13, and no rotation relationship is generated between the sliding block 13 and the sliding block 13.

[0031] In one embodiment, a push block 12 is fixedly mounted on the outer wall of one end of the positioning rod 11 to facilitate the operation of the position of the positioning rod 11 .

[0032] In one of the preferred embodiments, a rubber block 9 is fixedly installed at the telescopic end of the multi-stage telescopic rod 8. When the multi-stage telescopic rod 8 supports the device, the telescopic end of the multi-stage telescopic rod 8 will contact the platform through the rubber block 9, resulting in large friction, thereby increasing the stability of the device when it is placed in use.

[0033] In one of the embodiments, a plurality of balls 19 are movably mounted on the inner surface of the limiting slide 16, and the balls 19 are in rolling contact with the outer wall of the multi-stage telescopic rod 8, thereby reducing the friction between the slide 16 and the multi-stage telescopic rod 8, making it easier for the user to operate the position of the positioning rod 11.

[0034] In one preferred embodiment, a sliding hole adapted to the sliding rod 13 is provided on the sliding block 17 , and the sliding block 17 is slidably connected to the sliding rod 13 through the sliding hole provided thereon.

[0035] The working principle of the utility model is as follows: the specific structure of the metering device body 1 can refer to the prior art, which can be easily realized by those skilled in the art. The parts not involved in the device are the same as the prior art or can be realized by the prior art. When the user does not want to use the device by hand, the user can directly pull the multi-stage telescopic rod 8 so that the multi-stage telescopic rod 8 originally attached to the outer wall of the metering device body 1 forms a certain angle with the metering device body 1, and the stability of the multi-stage telescopic rod 8 after rotating a certain angle can be ensured through the rotation connection relationship between the multi-stage telescopic rod 8 and the damping shaft on the support 10, and then manually pull the telescopic end of the multi-stage telescopic rod 8 to extend and unfold the telescopic end of the multi-stage telescopic rod 8. After unfolding, the telescopic end of the multi-stage telescopic rod 8 has stability. By fully unfolding and stretching the three multi-stage telescopic rods 8, a stable triangular bracket is formed on the outer wall of the metering device body 1, and the metering device body 1 is stably placed on a platform. Subsequently, the placing plate 7 is connected to the hanging ring 4 through the hook 5 and installed at the bottom end of the cantilever beam weighing sensor 3 for weighing operation. This design uses three multi-stage telescopic rods to transform the device into a stable tripod as needed, thus avoiding the limitation of hand-held use. This method can effectively solve the hand fatigue and inconvenience caused by long-term weighing or frequent operation, and improve the work efficiency and comfort of users.

[0036] When the metering device is used in a hand-held manner, any multi-stage telescopic rod 8 is rotated to a vertical angle with the outer wall of the metering device body 1, and the push block 12 is manually moved, so that the push block 12 drives the positioning rod 11 to move, and the movement of the positioning rod 11 drives the slider 17 to slide on the outer wall of the slide rod 13 and squeeze the spring 15. After the positioning rod 11 is moved to an appropriate position and the multi-stage telescopic rod 8 is rotated to a vertical state with the metering device body 1, the limit of the push block 12 is released at this time, and the positioning rod 11 will be clamped into the inner part of the positioning groove 18 on the outer wall of the metering device body 1 under the elastic action of the spring 15, ensuring the stability of the multi-stage telescopic rod 8 in a vertical state. The user directly uses the multi-stage telescopic rod 8 in a vertical state as a handle to hand-hold the metering device body 1, and the clamping connection between the positioning rod 11 and the positioning groove 18 can ensure the stability of the device as a whole when hand-held by the multi-stage telescopic rod 8. The multi-functional use of the multi-stage telescopic rod 8 is high in practicality and convenient for people to use.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
