For driving guide post 614 to move inward so that inserted link 61 is detached from the arcuate socket 52 of arc groove 32 after dynamic, arcuate socket 52 is by elongated hole
51 one end are gradually curved inward;After by using this structure, when the inner wall in inserted link outer end and arc bump offsets, guide post
It can be moved inward along elongated hole, when inserted link snaps onto arc groove, guide post can be displaced outwardly along elongated hole, and such one
Come, inserted link is enabled to be inserted into arc groove, realizes the locking to retaining mechanism and fixing seat;Resetting-mechanism includes being sleeved on
The second torsional spring 7 in turntable 5 and support base 41 between bottom, for driving turntable 5 to rotate counterclockwise, second turns round the second torsional spring 7
One end of spring 7 and the lower end surface of turntable 5 are fixed, and the interior bottom of the other end and support base 41 is fixed;After by using this structure,
After handle mechanism rotates clockwise turntable, when handle mechanism is detached from turntable, turntable can reset under the action of the second torsional spring;
It is provided with the first jack 53 of the upper end insertion for the second torsional spring 7 on the lower end surface of turntable 5, is set on the interior bottom of support base 41
It is equipped with the second jack 415 of the lower end insertion for the second torsional spring 7;After by using this structure, the second torsional spring can be improved
With the fixing intensity of turntable and support base;Handle mechanism includes the shaft 81 being rotationally threaded through in the middle part of 42 upper surface of cover board,
The threaded upper ends of shaft 81 are connected with handle 82, and round table-like protrusion 55, the lower end of shaft 81 are provided on the upper surface of turntable 5
It is provided with when shaft 81 is pressed down for covering the cover 811 being attached to outside protrusion 55, if being provided on the periphery wall of protrusion 55
Arterial highway is in circumferentially distributed sawtooth 54, be provided on the internal perisporium of cover 811 quantity identical as sawtooth 54 and is used for and sawtooth
The tooth socket 812 of 54 engagements, 81 outer cover of shaft between handle 82 and cover board 42, which is equipped with, is used for driving handle 82 and shaft 81
It moves so that cover 811 is detached from the second spring 83 of protrusion 55;After by using this structure, when pushing handle cover is set with
Outside to protrusion and when making tooth socket and engagement, turntable can be driven to rotate clockwise by rotating clockwise handle, when
After turntable rotates clockwise, guide post can move in arcuate socket, so, inserted link be enabled to be detached from arc groove, thus
It can be realized the unlock to retaining mechanism and fixing seat;It is provided on the lower end surface of turning set 11 for the upper end of the first torsional spring 25
First blind hole 12 of insertion is provided with the second blind hole 26 of the lower end insertion for the first torsional spring 25 on the upper surface of bottom plate 21;
After by using this structure, the fixing intensity of the first torsional spring Yu turning set and bottom plate can be improved;If being provided in bottom plate 21
Dry is in circumferentially distributed bolt hole 27, is provided with a pair of of counter sink 34 on the interior bottom of fixing seat 3;Pass through setting for bolt hole
It sets, easily bottom plate can be fixed on doorframe by screw, by the setting of counter sink, can be incited somebody to action conveniently by screw
Bottom plate is fixed in door body;The one end of connecting rod 1 far from hinged seat 2 is fixed by bolt 13 and support base 41;By using this
After structure, the fixing intensity of connecting rod and support base can be improved;When the utility model is used, when it is required that retaining mechanism with
When fixing seat is locked, pivot link and retaining mechanism first enters retaining mechanism in fixing seat, enters in retaining mechanism
During fixing seat, the inclined-plane on inserted link can cooperate with the inner wall of arc bump to be oriented to, and inserted link can be extruded inward, lead
Column can move inward in elongated hole, and when inserted link is moved to arc groove position, inserted link can be in the first spring
It being inserted into arc groove under effect, guide post can be displaced outwardly in elongated hole, after inserted link is inserted into arc groove, Neng Goushi
The locking to door body now can be realized after retaining mechanism and fixing seat locking to the locking of retaining mechanism and fixing seat;When need
When retaining mechanism and fixing seat are unlocked, handle is pressed down on, so that cover is provide with the outside of protrusion, and makes tooth socket
With engagement, handle is then rotated clockwise, handle is able to drive shaft, cover and turntable and rotates clockwise, when turntable is suitable
After hour hands rotation, guide post can move in arcuate socket, so, inserted link be enabled to move inward, inserted link moves inward
Afterwards, inserted link can be detached from arc groove, and so as to realize the unlock to retaining mechanism and fixing seat, then people pass through rotation lock
Tight mechanism and connecting rod, after retaining mechanism removes fixing seat, it is vertical that connecting rod can turn to automatically under the action of the first torsional spring
State so realizes the unlock to door body;And in above process, when people do not push handle, even if handle
It is rotated, turntable will not rotate, and so, can be avoided the phenomenon that lock is misread in appearance.
It should be noted that in the embodiment above, as long as reconcilable technical solution can carry out permutation and combination, this
Field technical staff can be according to the exhaustive all possibility of mathematical knowledge of permutation and combination, and therefore, the present invention is no longer to permutation and combination
Technical solution afterwards is illustrated one by one, but it is understood that presently disclosed for the technical solution after permutation and combination.
