When the second connecting piece 2 drives the clamping piece 3 to move, the lower sliding pin 393 moves from the inclined slot 15 to the straight slot 14, and under the guidance of the straight slot 14, the lower end of the clamping piece 3 is inclined towards the side away from the second connecting piece 2, and then the lower end of the clamping piece 3 is reset to be inclined towards the side close to the second connecting piece 2, so that the connecting clamping block 21 is clamped in the clamping space 39 to limit the movement of the second connecting piece 2. When the second connecting piece 2 is pressed again, the lower sliding pin 393 moves from the straight slot 14 to the inclined slot 15, and under the guidance of the inclined slot 15, the lower end of the clamping piece 3 is inclined towards the side away from the second connecting piece 2, so that the connecting clamping block 21 is separated from the clamping space 39, and the second connecting piece 2 can be taken out.

[0060] As shown in the accompanying drawings Figure 1 to the accompanying drawings Figure 6As shown, further, the connecting block 11 is further provided with a turning groove 16 communicated with the straight groove 14, and the clamping hook 4 is movably arranged in the straight groove 14 and the turning groove 16. When connecting, the clamping portion 41 of the clamping hook 4 moves from the third sliding groove 36 and the second connecting groove 38 to abut against the protrusion 31 through the straight groove 14 and the turning groove 16, and when disassembling, the clamping portion 41 of the clamping hook 4 moves from the second connecting groove 38 to the fourth sliding groove 37 through the straight groove 14 and the turning groove 16, and the clamping portion 41 is disconnected with the protrusion 31. The structure is simple and ingenious, and the clamping and disconnection of the first connecting piece 1 and the second connecting piece 2 are accurately switched under the guidance of the straight groove 14 and the turning groove 16, so that the disassembling speed is accelerated.

[0061] Further, the connecting block 11 is further provided with a leakage outlet 111 for partially leaking the clamping piece 3 and a turning groove 16 communicated with the straight groove 14. The leakage outlet 111 is inclined to the direction away from the second connecting piece 2 at the lower end of the clamping piece 3 for partially leaking. When the second connecting piece 2 drives the clamping piece 3 to move, the clamping piece 3 is guided by the side wall on the other side of the protrusion 31, so that the clamping piece 3 is conveniently clamped with the second connecting piece 2, the clamping portion 41 enters the turning groove 16, and at this time, the clamping groove 35 is located at the upper end of the turning groove 16 in the direction of pressing the second connecting piece 2. When the second connecting piece 2 is released, the clamping portion 41 enters the clamping groove 35.

[0062] Further, the connecting block 11 is further provided with a spring 17 and a pressing plate 18. The pressing plate 18 is provided with a spring shaft 181, the spring 17 is sleeved on the spring shaft 181, the clamping piece 3 is provided with a spring hole 394 for inserting the spring shaft 181, and the two ends of the spring 17 are respectively abutted against the bottom wall of the spring hole 394 and the pressing plate 18. The clamping piece 3 has a tendency to move away from the pressing plate 18. When the clamping portion 41 enters the clamping groove 35 from the second sliding groove 33 and the second connecting piece 2 is released, the clamping piece 3 moves away from the pressing direction under the elastic force of the spring 17, so that the clamping portion 41 is guided by the inner wall of the clamping groove 35 close to the second sliding groove 33 and enters the clamping groove 35.

[0063] Working principle: as shown in the attached Figure 15As shown, during connection, pressing the second connector 2 causes it to be inserted from the end of the first connector 1 away from the connecting block 11 into the receiving cavity 13. The upper surface of the connecting block 21 will first abut against the first locking block 391, causing the second connector 2 to move the locking member 3. During the movement of the locking member 3, the locking part 41 moves within the third sliding groove 36, and the spring 17 is compressed until the locking part 41 moves from the farthest end of the third sliding groove 36 away from the pressure plate 18, and the locking member 3 moves to its limit position. At this time, the second connector 2 is released, and under the elastic force of the spring 17, the locking member 3 moves away from the pressing direction, and the locking part 41 returns along the original path within the third sliding groove 36. During this process, the sliding pin 393 located below moves from the inclined groove 15 into the straight groove 14, causing the straight groove 14 to... Under guidance, the lower end of the snap-fit ​​component 3, which was tilted away from the second connector 2, is reset and aligned towards the second connector 2. That is, the snap-fit ​​component 3 and the second connector 2 are arranged parallel to each other, so that the connecting snap-fit ​​block 21 is snapped into the snap-fit ​​space 39. That is, the lower end face of the connecting snap-fit ​​block 21 will abut against the second snap-fit ​​block 392, and the snap-fit ​​component 3 and the second connector 2 are snapped together. At the same time, during the alignment of the snap-fit ​​component 3, the third sliding groove 36 of the snap-fit ​​part 41 can be guided to deflect and abut against the protrusion 31. That is, the distance between the farthest end of the third sliding groove 36 away from the pressure plate 18 and the protrusion 31 is equal to the distance that the sliding pin 393 located below moves from the inclined groove 15 to the straight groove 14 when the second connector 2 is released, restricting the movement of the snap-fit ​​component 3, thereby allowing the first connector 1 and the second connector 2 to be connected.

[0064] As attached Figure 16 As shown, during disassembly, pressing the second connector 2 causes the second connector 2 to move the locking member 3. When the locking part 41 passes the limiting part 311 and moves from the second connecting groove 38 into the fourth sliding groove 37, the second connector 2 is released. Under the elastic force of the spring 17, the locking member 3 moves away from the pressing direction, and the locking part 41 resets under the guidance of the fourth sliding groove 37. At this time, the sliding pin 393 located below moves from the straight groove 14 into the inclined groove 15, so that under the guidance of the inclined groove 15, the lower end of the locking member 3 tilts away from the second connector 2, thereby causing the lower end face of the connecting block 21 to disengage from the second locking block 392, that is, the connecting block 21 disengages from the locking space 39, and the second connector 2 can be removed from the receiving cavity 13, as shown in the attached figure. Figure 13As shown, after disassembly is completed, the lower end of the clamping piece 3 is inclined towards the direction away from the second connecting piece 2, so that the upper end surface of the connecting clamping block 21 can first abut against the first clamping block 391 during the next installation, so that the second connecting piece 2 drives the clamping piece 3 to move.

[0065] As shown in the accompanying Figure 1 to the accompanying Figure 16 As shown, further, the first connecting piece 1 is configured as a fixed piece, the first connecting piece 1 is fixed on the shell of the instrument, the second connecting piece 2 is configured as a detachable piece, the second connecting piece 2 is used to install the battery. The hook 4 is used for control, the clamping piece 3 is connected or disconnected with the first connecting piece 1 or the second connecting piece 2, without using tools, the first connecting piece 1 and the second connecting piece 2 can be quickly disassembled and assembled, the battery can be quickly disassembled and assembled, in the case of needing to quickly replace the battery or charging, the connection disassembly structure is more convenient and fast, the disassembly speed is accelerated, and the battery replacement efficiency is improved.
