After the body 1 is placed into the protective shell 3, the plug-in block 81 is pushed to slide through the inclined surface on the plug-in block 81, and after the body 1 is completely placed in the protective shell 3, the plug-in block 81 is engaged with the back groove 17. When the body 1 is taken out of the protective shell 3, the protective shell 3 is rotated to overcome the force of the torsion spring 72. During the rotation of the protective shell 3, the sliding member 83 moves up, and after the guide pin 84 moves from the bottom of the guide groove 82 to the vertical part, the plug-in block 81 slides and disengages from the back groove 17.

When the protective shell 3 rotates, the abutment shell 9 is disengaged from the lifting shell 8. When the protective shell 3 rotates, the distance between the abutment shell 9 and the lifting shell 8 is lengthened, and the connecting rope 8 5, the sliding member 83 slides to compress the seventh spring 86. During the sliding process of the sliding member 83, the guide pin 84 moves up with the sliding member 83. When it moves up to the vertical part of the guide groove 82, the plug-in block 81 is separated from the back groove 17. If a snatch occurs, the protective shell 3 rotates too much due to the large force during the snatching process. Under the pulling action of the connecting rope 85, the sliding member 83 moves up, so that the guide pin 84 moves to the top of the guide groove 82. At this time, under the action of the guide pin 84 and the guide groove 82, the plug-in block 81 slides and re-engages with the back groove 17 , limiting the removal of the machine body 1, improving the difficulty of snatching and safety; under the action of the torsion spring 72, the protective shell 3 is parallel to the back clip 7, and the lifting shell 8 is abutted against the abutment shell 9; during use, the adjusting plate 91 can be slid by rotating the bolt 92 to loosen the connecting rope 85. After the connecting rope 85 is loosened, the protective shell 3 rotates, and the connecting rope 85 is first tightened, and then the sliding member 83 is pulled by the connecting rope 85 to slide, so as to control the sliding of the plug-in block 81. Conversely, the protective shell 3 can be adjusted by rotating the bolt 92 to disengage the plug-in block 81 from the back groove 17. The angle of rotation; when the body 1 is taken out, under the abutment of the lifting shell 8 and the abutment shell 9, the pressing plate 31 pushes the body 1 to move upward, and through the engagement of the plug-in block 81 with the back groove 17, the lifting shell 8 and the abutment shell 9 slide upward as the body 1 rises, and then the protective shell 3 rotates, and the body 1 can be taken out. When the body 1 is placed into the protective shell 3, the body 1 pushes the plug-in block 81 to make the lifting shell 8 and the abutment shell 9 descend, and after descending to the bottom, the body 1 pushes the plug-in block 81 to slide through the inclined surface on the plug-in block 81, completing the engagement of the plug-in block 81 with the back groove 17.

[0053] Working principle: when in use, fix the back clip 7 to the belt or chest. After the machine body 1 is used, place the machine body 1 in the protective shell 3 and press it down. During the pressing process, the pressing plate 31, the vertical rod 32 and the pull rod 34 slide downward. During the sliding process, the third spring 33 and the fourth spring 36 are compressed. When the machine body 1 pushes the pressing plate 31 to move down to the bottom, the pressing plate 31 presses the lifting rod 5, the lifting rod 5 moves downward, the fifth spring 52 is compressed, and the force storage block 51 and the force storage groove 45 are separated. At this time, under the action of the fourth spring 36, the sliding tube 35 slides downward and passes through the protrusion 3 7 and the inclined groove 42 make the clamping block 4 slide, and the engaging pin 41 on the clamping block 4 engages with the engaging groove 16 on the body 1 to complete the fixation of the body 1; when the clamping block 4 slides, the locking block 61 is pushed by the inclined surface on the locking block 61 to make the locking block 61 slide and disengage from the first locking groove 43, and the sixth spring 62 is compressed. After the sliding of the clamping block 4 is completed, the engaging pin 41 engages with the engaging groove 16, and the second locking groove 44 moves the position of the locking block 61, under the action of the sixth spring 62, the locking block 61 engages with the second locking groove 44 to complete the locking of the clamping block 4; the body 1 is pressed down to When the protective shell 3 is inside, the plug-in block 81 slides under the abutment of the inclined surface and the body 1, and the sliding member 83 rises to compress the seventh spring 86 through the action of the guide groove 82 and the guide pin 84 to complete the sliding of the plug-in block 81. After the body 1 is lowered to align the back groove 17 with the plug-in block 81, the plug-in tube slides and engages with the back groove 17 under the action of the seventh spring 86; when the body 1 is taken out for use, the pressing members 63 on both sides of the protective shell 3 are pressed and fixed, and the locking member 6 slides through the inclined surface extrusion, and the locking block 61 is disengaged from the second locking groove 44. At this time, the third spring 86 is pressed to lock the locking member 61. Under the reset action of the spring 33, the sliding tube 35 rises, and the clamping block 4 slides under the action of the protrusion 37 and the inclined groove 42, the clamping pin 41 is disengaged from the clamping groove 16, and the pressing plate 31 rises and resets, pushing a part of the machine body 1 upward; and in this process, the pressing plate 31 is disengaged from the lifting rod 5, and the lifting rod 5 is reset under the action of the fifth spring 52. During the reset process of the clamping block 4, the inclined surface on the force storage block 51 is used to prevent the force storage block 51 from hindering the reset of the clamping block 4, and after the clamping block 4 is reset, the force storage block 51 is clamped with the force storage groove 45 under the action of the fifth spring 52;When the pressing plate 31 pushes the machine body 1 to rise upward, under the clamping action of the plug-in tube and the back groove 17, the lifting shell 8 and the abutting shell 9 slide upward with the rise of the machine body 1. After the machine body 1 is moved up, the machine body 1 and the protective shell 3 overcome the force of the torsion spring 72 to rotate. At this time, the protective shell 3 rotates relative to the back clamp 7. When the protective shell 3 rotates, the abutting shell 9 and the protective shell 3 are separated from the abutment, and the distance between them is continuously increased. During the rotation of the protective shell 3, the tensile force of the connecting rope 85 causes the sliding member 83 to compress the seventh spring 86 and move upward. During the upward movement, the guide pin 84 on the sliding member 83 cooperates with the guide groove 82 to make the plug-in block 81 slide. When the guide pin 84 slides from the bottom of the guide groove 82 to the vertical part, the plug-in tube and the back groove 17 are completely separated, and the machine body 1 can be taken out for use. After being taken out, the protective shell 3 can be rotated and reset under the action of the torsion spring 72. If a snatching phenomenon occurs, the force is difficult to control during the snatching process, which will cause the protective shell 3 to rotate too much, and the sliding member 83 to rise excessively. The guide pin 84 slides to the top of the guide groove 82, and the guide pin 84 is not in the vertical part of the guide groove 82. At this time, the plug-in block 81 will still be engaged with the back groove 17 under the action of the guide pin 84 and the guide groove 82, limiting the movement of the machine body 1, thereby preventing the machine body 1 from being easily snatched. ;

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
