An embodiment of the present invention provides a front clutch for a lock, as shown in fig. 1 and 2, comprising a rotary core 100, a first clutch knob 200, a second clutch knob 300, a torsion spring 400, and a direction adjusting knob 500.

The rotary core 100 is an unlocking component, the unlocking and locking of the front clutch of the lockset are realized through the rotation of the rotary core 100, the first clutch knob 200 is connected with the rotary core 100 in a synchronous rotation manner, in the embodiment, the first clutch knob 200 and the rotary core 100 are integrally formed, and further the first clutch knob 200 and the rotary core 100 can synchronously rotate, in other embodiments, the rotary core 100 and the first clutch knob 200 can be designed into a split structure, so that the first clutch knob and the first clutch knob are connected through a thread structure, or an intermediate connecting piece is arranged between the first clutch knob and the rotary core, and the synchronous rotation of the first clutch knob and the first clutch knob can be realized.

The second clutch knob 300 is connected with the direction adjustment knob 500 in a synchronous rotation manner, as shown in fig. 1 and 2, coaxial shaft holes are formed in the second clutch knob 300 and the direction adjustment knob 500, the shaft holes are of quadrilateral structures, and the square shaft 600 is inserted into the shaft holes of the second clutch knob 300 and the direction adjustment knob 500 and has the same quadrilateral structure, so that the second clutch knob 300, the direction adjustment knob 500 and the square shaft 600 are linked in the rotation direction, namely, are synchronously rotated. In other embodiments, the shaft hole may be triangular or polygonal, or the second clutch knob 300, the direction adjustment knob 500 and the square shaft 600 may be engaged by a key.

The torsion spring 400 includes a pair of free ends 410 disposed opposite to each other, the first clutch knob 200 has a first extending arm 210, the second clutch knob has a second extending arm 310, the first extending arm 210 and the second extending arm 310 are disposed between the pair of free ends 410 disposed opposite to each other, a positioning member 910 (as shown in fig. 7) is further disposed between the pair of free ends 410, the positioning member 910 is fixedly disposed, when the first clutch knob 200 rotates, the corresponding free ends 410 are driven to rotate synchronously, the torsion spring 400 contracts and the restoring force is gradually increased, and the other free end 410 is blocked by the positioning member 910, so that the second clutch knob 300 does not rotate synchronously with the rotation of the first clutch knob 200, and when the acting force on the first clutch knob 200 disappears, the first clutch knob 200 is quickly restored to its initial position under the reactive force of the torsion spring 400.

Further, the abutting wall 220 is arranged on the first clutch knob 200, the push post 510 extending out to the first clutch knob 200 is arranged on the direction adjusting knob 500, when the rotary core 100 rotates clockwise, the first clutch knob 200 rotates simultaneously, the abutting wall 220 abuts against the push post 510, and the direction adjusting knob 500 rotates continuously, so that the direction adjusting knob 500 rotates synchronously with the first clutch knob 200, at the same time, the rotary core 100, the first clutch knob 200, the second clutch knob 300, and the direction adjusting knob 500 rotate synchronously to complete the unlocking action, after the driving force of the rotary core 100 disappears, under the action of the torsion spring 400, the first clutch knob 200 and the second clutch knob 300 return to the initial positions, and the direction adjusting knob 500 returns to the initial positions under the driving of the second clutch knob 300, so as to avoid the square shaft 600 from being locked. It can be seen that the torsion spring 400 can keep the first and second clutch knobs 200 and 300 at the same relative position without stress, so that the clutch of the clutch is not dislocated.

Referring to fig. 3, which shows a schematic structural diagram of the first clutch knob in an embodiment, an annular wall 230 protruding upward is provided on the first clutch knob 200, the annular wall 230 is in a semi-annular structure, an installation space for installing the second clutch knob 300 is formed on the inner wall of the annular wall 230 and the surface of the first clutch knob 200, one end of the annular wall 230 forms the above-mentioned abutting wall 220 for cooperating with the push post 510, the direction adjustment knob 500 is driven to rotate together when the rotary core 100 rotates clockwise, an idle-avoiding position is formed on the other side of the annular shape defined by the annular wall 230, when the rotary core 100 rotates counterclockwise, the first clutch knob 200 can rotate relative to the direction adjustment knob 500, and the abutting wall 240 is formed at the other end of the annular wall 230, and a limit for avoiding the idle-avoiding position is formed.

As shown in fig. 1 and 2, the bearing 110 is further sleeved on the rotating core 100, and the bearing 110 is attached to the first clutch knob 200 to ensure that the first clutch knob 200 moves more smoothly.

Still the cover is equipped with jump ring 120 on the core 100 that changes, provides spacing for the installation of the part on the core 100 changes.

In one embodiment, the front lock clutch further includes a motor 700, a push plate 710 and a pin shaft 720, and the first clutch knob 200 and the second clutch knob 300 are provided with pin grooves 800 that are communicated with each other. The pin shaft 720 is located on the axis of the pin groove 800, the push plate 710 is arranged at the output end of the motor 700, the motor 700 works to enable the push plate 710 to move towards the directions of the first clutch knob 200 and the second clutch knob 300, and then the pin shaft 720 is pushed to be inserted into the pin groove 800, so that the locking of the first clutch knob 200 and the second clutch knob 300 is realized, when the pin shaft 720 is completely inserted into the pin groove 800, the first clutch knob 200 and the second clutch knob 300 are locked together, and the constant linkage is kept. In this embodiment, the push plate 710 preferably has a ring structure to ensure that the pin shaft 720 can be provided with a driving force to the pin groove 800 even if the first and second clutch knobs 200 and 300 and the pin shaft 720 rotate at a certain angle.

In one embodiment, a spring is sleeved on the pin 720, and when the driving force on the pin 720 disappears, the pin 720 can automatically return to unlock the first clutch knob 200 and the second clutch knob 300 under the action of the spring.

As shown in fig. 5 to 7, a schematic structural diagram of a front lock clutch according to an embodiment is shown, in this embodiment, the front lock clutch further includes a housing 900, the housing 900 may be an integral body formed by integral molding or an integral body formed by assembling multiple parts together, in this embodiment, the positioning member 910 is preferably a part of the housing 900, that is, is integrally formed on the housing 900, so as to facilitate processing and production.

An embodiment of the utility model provides a tool to lock still provides, it includes as above clutch before the tool to lock.
