In this embodiment, as shown in fig. 4, the cover body 210 is provided with a first limiting member 212, the first limiting member 212 protrudes from a surface of the cover body 210 adjacent to the accommodating cavity 102, the first limiting member 212 extends toward the accommodating cavity 102, and the first limiting member 212 can limit a relative position between the test strip 3 and the cover body 210 when the test strip 3 is located in the accommodating cavity 102. When an operator holds the hand-held analyzer with the test strip 3 inserted therein and changes the holding direction, the test strip 3 is not easily separated from the analyzer body 1 due to the abutting action of the first stopper 212 on the surface of the test strip 3. As shown in fig. 5, in order to cooperate with the first limiting member 212, a limiting groove 301 is formed on the surface of the test strip 3 at a position corresponding to the first limiting member 212, and when the test strip 3 is inserted into the analyzer body 1, the first limiting member 212 abuts against a groove wall of the limiting groove 301.

Thus, the limiting block 2122 can be more easily separated from the test strip 3 under the action of external force, so that an operator can take out the test strip 3 from the test strip socket 101 conveniently.

In another embodiment, both ends of the elastic sheet 2121 are fixedly connected to the cover 210, the limiting block 2122 is located at the middle of the bottom surface of the elastic sheet 2121, and the middle of the elastic sheet 2121 can move relative to the cover 210.

In another embodiment, the first limiting member 212 may not include the elastic sheet 2121, and the relative position of the limiting block 2122 and the cover 210 is fixed.

In this embodiment, the cover 210 is provided with a guide block 213, the accommodating member 160 is provided with a guide groove 163, and a portion of the guide block 213 is disposed in the guide groove 163 and can slide along the guide groove 163.

Through the cooperation of the guide blocks 213 and the guide grooves 163, the relative sliding between the cover 210 and the receiving member 160 is smooth, and the sliding direction and the limit position of the cover 210 relative to the receiving member 160 are limited. Of course, the positions of the guide blocks 213 and the guide grooves 163 on the cover 210 and the receiving member 160 may be interchanged.

In this embodiment, two opposite side portions of the accommodating member 160 are respectively provided with a second limiting member 161 protruding the surface thereof, and two second limiting members 161 are disposed on each side surface, wherein one of the second limiting members 161 abuts against the guide block 213 to stop the trend of the cover 210 moving from the second position to the first position when the cover 210 is at the first position, and the other second limiting member 161 abuts against the guide block 213 to stop the trend of the cover 210 moving from the first position to the second position when the cover 210 is at the second position.

In other embodiments, only one second stopper 161 may be provided on each side surface of the receiving member 160, so as to prevent only a movement tendency of the cover body 210 from the second position to the first position, or only a movement tendency of the cover body 210 from the first position to the second position. Alternatively, the accommodating member 160 may not be provided with the second limiting member 161, and the limiting of the cover 210 at the first position and the second position may be achieved only by the cooperation of the guide block 213 and the guide groove 163.

In this embodiment, the bottom of the guiding groove 163 has a slope, and the slope of the slope forms an acute angle with the extending direction of the holding member 160 from the test strip slot 101 to the baffle 211. When the cover body 210 moves from the first position to the second position, the guide block 213 moves along the inclined plane of the groove bottom of the guide groove 163 to drive the cover body 210 to gradually approach the accommodating part 160, so that the distance between the cover body 210 and the accommodating part 160 is gradually reduced, and the inner wall of the top of the cover body 210 compresses the test strip 3 towards the groove bottom of the accommodating part 160, thereby further limiting the relative position between the test strip 3 and the cover body 210, and the test strip 3 is more difficult to be separated from the analyzer body.

In the present embodiment, referring to fig. 3 again, the dial 242 includes a dial body 2421 and a protrusion 2422 provided on the surface of the dial body 2421, the protrusion 2422 extends towards the holder 220, the maximum thickness of the protrusion 2422 is greater than the minimum distance between the inner side of the first holder 2201 and the outer side wall of the receiver 160 opposite to the inner side, so that when the protrusion 2422 is inserted between the first holder 2201 and the outer side wall of the receiver 160, the first holder 2201 is supported to move away from the outer side wall of the receiver 160 along with the movement of the protrusion 2422, and the first holder 2201 and the second holder 2202 are switched from the abutting state to the separating state.

In this embodiment, as shown in fig. 6, a position-limiting hole 111 is formed in the surface of the upper housing 110, a part of the key 241 penetrates through the position-limiting hole 111, and the position-limiting hole 111 is used for limiting the sliding displacement of the key 241 relative to the analyzer body 1.

In this embodiment, after the test strip 3 is inserted into the test strip socket 101, the analysis method further includes the following steps: the first stopper 212 abuts against the surface of the test strip 3.

In this embodiment, the analyzer body 1 obtaining the trigger signal includes the following steps: the trigger protrusion 214 abuts against the trigger switch 171, so that the trigger unit 170 generates a trigger signal. Specifically, in the process of moving the cover 201 from the first position to the second position, the trigger protrusion 214 gradually contacts and covers the trigger switch 171, and when the trigger switch 171 is completely covered, the trigger unit 170 generates the trigger signal. In the process of displacing the actuator 240 from the initial position with respect to the analyzer body 1 to the actuation position at which the at least two holders 220 are switched from the abutting state to the separated state, the trigger protrusion 214 gradually releases the covering of the trigger switch 171. Of course, in another embodiment, the trigger protrusion 214 may be configured not to cover the trigger switch 171, but only abut against the trigger switch 171 to enable the trigger unit 170 to generate the trigger signal.
