Specifically, a locking mechanism 8 is arranged in the mounting shell 1, the locking mechanism 8 includes a cavity formed in the front interior of the mounting shell 1, a transverse plate is fixedly connected in the cavity, a sliding sleeve is connected to the upper surface of the transverse plate in a clamping manner, a sliding rod 82 is sleeved in the sliding sleeve, a clamping block 81 is fixedly connected to the top end of the sliding rod 82, the clamping block 81 is clamped in the rotating plate 35 on the lower side, a fifth spring 83 is sleeved on the outer side of the sliding rod 82, two ends of the fifth spring 83 are respectively and fixedly connected with the opposite surfaces of the clamping block 81 and the sliding sleeve, a third magnet block 84 is fixedly connected to the bottom end of the sliding rod 82, by arranging the locking mechanism 8, the clamping block 81 can be inserted into the rotating plate 35 to fix the rotating plate 35, the fan-shaped cap 31 is prevented from being automatically separated from the protective cap 32 to cause false touch, by arranging the third magnet block 84, when the first magnet 22 moves to the lower side, and drive fixture block 81 through locating lever 95 and move down and no longer fix rotating-piece 35, rotating-piece 35 can rotate this moment and let fan-shaped cap 31 be opened, through setting up fifth spring 83, when third magnet piece 84 no longer is adsorbed, fifth spring 83 moves fixture block 81 through self elasticity extension and shifts up card post rotating-piece 35 once more.

Specifically, the timing mechanism 2 includes a knob housing 21 fixedly connected to the front of the fixed housing 5, a shaft sleeve 24 is disposed in the knob housing 21, a threaded ring 25 is fixedly connected to the outer side of the shaft sleeve 24, both the left and right side surfaces of the threaded ring 25 are fixedly connected with a first magnet block 22, the first magnet block 22 is located in an annular cavity 23 formed in the mounting housing 1, a plurality of through holes 7 are formed in the front of the mounting housing 1 corresponding to the annular cavity 23, the through holes 7 are symmetrically distributed on the left and right sides and the upper and lower sides, an arc hole is formed in the front of the knob housing 21 corresponding to the threaded ring 25, by providing a locking mechanism 8, wherein a fixture block 81 can be inserted into the rotating plate 35 to fix the rotating plate 35, thereby preventing the fan-shaped cap 31 from being automatically separated from the protective cap 32 to cause the occurrence of false touch, by providing a third magnet block 84, when the first magnet block 22 moves to the, at this moment, the third magnet block 84 is adsorbed to move downwards, the positioning rod 95 drives the fixture block 81 to move downwards to fix the rotating piece 35, the rotating piece 35 can rotate to open the fan-shaped cap 31, and the fifth spring 83 is arranged to extend through the elastic force of the fifth spring 83 to push the fixture block 81 to move upwards to clamp the column rotating piece 35 again when the third magnet block 84 is not adsorbed.

The working principle is as follows: if disassembly is required, the control thread ring 25 rotates to drive the first magnet block 22 to be no longer located at the front side of the second magnet block 610 and move to the lower side of the third magnet block 84, at this time, the third magnet block 84 is adsorbed to move downwards, and the positioning rod 95 drives the fixture block 81 to move downwards and no longer fix the rotating sheet 35, at this time, the rotating sheet 35 can rotate to open the fan-shaped cap 31, the third spring 62 extends through its own elasticity to push the first sliding block 61 to move, the first sliding block 61 moves to drive the inserting pin 68 to move through the positioning column 69, at this time, the inserting pin 68 can be separated from the slot and no longer fix the supporting rod, when the pressing inserting rod 41 moves backwards, the trapezoidal block 44 is driven to move backwards, the inclined plane of the trapezoidal block 44 no longer forms an extrusion effect on the blocking rod 45, at this time, the second spring 46 pulls the blocking rod 45 to move through its own elasticity, at this time, the, thereby make branch no longer fixed, the connecting rod drives clamp plate 48 and removes no longer to form the extrusion effect to baffle 66 simultaneously, fourth spring 65 pushes up through self elasticity extension this moment and moves baffle 66 forward, baffle 66 strikes branch and pops out timing mechanism 2, realize quick dismantlement, during the middle part of pulling stay cord 92, two position sleeves can be pulled simultaneously at the both ends of stay cord 92 and are close to each other, two position sleeves drive two sets of couples 93 and no longer hang the latch closure when being close to each other, make knob shell 21 no longer fixed, can easily take out knob shell 21 simultaneously.
