In, drive spacer pin 212 to engage or separate with gear wheel 5 in the presence of control unit 31；The one end of accommodating chamber away from gear wheel 5
Block piece 6 is provided with, block piece 6 is used to stop guide and limit portion 211, prevents moving member 21 from departing from accommodating chamber.
Moving member 21 includes guide and limit portion 211 and the spacer pin 212 being fixed together, and is moved in the presence of control unit 31
Moving part 21 is slided along guide and limit portion 211, realizes that spacer pin 212 engages or separated with gear wheel 5.Accommodating chamber is away from gear wheel 5
One end be provided with block piece 6, can prevent moving member 21 from departing from from accommodating chamber again.
In the present embodiment, as shown in figure 5, guide and limit portion 211 can include guide part 2111 and solid with guide part 2111
The limiting section 2112 being connected together；Limiting section 2112 is located at one end away from control unit 31 on guide part 2111, and limiting section
2112 and guide part 2111 be arranged side by side along the direction vertical with the direction of motion of moving member 21；Block piece 6 includes being used to stop
The stopper of limiting section 2112, stopper is oppositely arranged with limiting section 2112, and stopper is located at accommodating chamber away from gear wheel 5
One end.
Stopper is oppositely arranged with limiting section 2112, can prevent moving member 21 from departing from during being slided with respect to accommodating chamber
Accommodating chamber.
Guide part 2111 and limiting section 2112 are affixed, specifically, can be integrally connected or welding, etc..
In the present embodiment, as shown in figure 5, the top of spacer pin 212 can be provided with chamfering or fillet.
Chamfering or fillet are set on the top of spacer pin 212, make the top of spacer pin 212 be easier to be caught in gear wheel 5
Tooth in.
In the present embodiment, as shown in figure 5, dynamic clamping head and quiet clamping head 22 can be spring, spring housing is on spacer pin 212.
Dynamic clamping head and quiet clamping head 22 is the spring being sheathed on spacer pin 212, while 22 function of dynamic clamping head and quiet clamping head is ensured,
Make the setting of dynamic clamping head and quiet clamping head 22 more easy.
In the present embodiment, as Figure 1-5, roller 23 can also be included from lock set 2, roller 23 is articulated in guiding limit
The one end of position portion 211 away from gear wheel 5；Roller 23 is located at outside accommodating chamber, and roller 23 is closely abutted with control unit 31.
Roller 23 is pivotally connected in guide and limit portion 211, outside accommodating chamber, roller 23 is closely abutted with control unit 31, in height
The opposed gear case 1 of tap mounting shell 3 is rotated, and control unit 31 is extruded and promoted during the lock set 2, and roller 23 is oppositely oriented
Limiting section 211 is rotated, and can reduce the abrasion of control unit 31.
In the present embodiment, as shown in fig. 6, control unit 31 can include consistency of thickness for fan-shaped control unit, fan-shaped control unit
The first fan-shaped control unit 311, be gradually reduced along circular arc direction thickness the 3rd of the second fan-shaped control unit 312 and consistency of thickness
Fan-shaped control unit 313；The thickness of first fan-shaped control unit 311 is more than or equal to the maximum gauge of the second fan-shaped control unit 312, the
One fan-shaped control unit 311 side maximum with the second fan-shaped thickness of control unit 312 is affixed；The thickness of 3rd fan-shaped control unit 313
Consistent with the minimum thickness of the second fan-shaped control unit 312, the 3rd fan-shaped fan-shaped thickness of control unit 312 of control unit 313 and second is most
Small side is affixed；The first fan-shaped control unit 313 of the fan-shaped fan-shaped control unit 312 and the 3rd of control unit 311, second is arranged concentrically；
When engaging from lock set 2 with gear wheel 5, the first fan-shaped control unit 311 is closely abutted with from lock set 2；From lock set 2 and canine tooth
When wheel 5 is separated, the 3rd fan-shaped control unit 313 is closely abutted with from lock set 2.
Control unit 31 is arranged on high tap mounting shell 3, by the first fan-shaped control unit 311 of consistency of thickness, along circular arc side
3rd fan-shaped control unit 313 of the second fan-shaped control unit 312 and consistency of thickness being gradually reduced to thickness is constituted, and rotates high tap
Mounting shell 3, when the first fan-shaped control unit 311 from lock set 2 with closely abutting, engages from lock set 2 with gear wheel 5；When
Three fan-shaped control units 313 with from lock set 2 closely abut when, completely disengage from gear wheel 5 from lock set 2, enable gear wheel 5 just
Often work.Control unit 31 is made up of the first fan-shaped control unit 313 of the fan-shaped fan-shaped control unit 312 and the 3rd of control unit 311, second
When, the engaging with gear wheel 5 of self-locking component 2 can be achieved during the high opposed gear case 1 of tap mounting shell 3 is rotated or divide
From without carrying out extra operation, operating process is more simple.
In the present embodiment, as shown in fig. 6, the first fan-shaped control of the fan-shaped fan-shaped control unit 312 and the 3rd of control unit 311, second
The fan-shaped central angle that portion 313 processed is formed is obtuse angle.
The fan-shaped circle of the first fan-shaped fan-shaped formation of control unit 313 of the fan-shaped control unit 312 and the 3rd of control unit 311, second
When heart angle is obtuse angle, the central angle of control unit 31 is larger, can reduce or even prevent to depart from the situation of control unit 31 from lock set 2
Occur.
Embodiment two
