The gear case 12 includes an integral input/output shaft 121 and a synchronous rotating member 122 disposed on the surface, and the synchronous rotating member 122 rotates in synchronization with the input/output shaft 121. The gear box is a common upper gear box on the market, also known as the upper chain gear box. Its working principle is to twist the upper chain handle 13 and input the rotary motion into the gear box through the input shaft to make the spring inside the gear box. The accumulating force is tightened, and the restoring force of the spring after the release of the upper handle 13 drives the output shaft to rotate. The gearbox can be a separate input shaft and output shaft, or an integral input/output shaft 121, which is preferred in this embodiment. The specific internal structure of the gearbox will not be described here.

a first end of the winding handle 13 protrudes out of the front portion 112 of the second head housing through the upper chain hole 1121, and a second end of the upper handle is fixedly sleeved on the input/output shaft 121. The second end of the upper chain handle 13 is further provided with a one-way clutch buckle 131, and the rotary output member 15 is sleeved on the one-way clutch buckle 131; the rotary output member 15 is a gear, and the inner circumference thereof The inner ring gear 151 is matched with the one-way clutch buckle 131, and the outer circumferential surface thereof is provided with an outer ring gear 152 that meshes with the rotating water outlet member 16; when the rotating handle follows the upper chain of the gear box When the direction is rotated, the input/output shaft 121 rotates synchronously, the one-way clutch button 131 idles in the ring gear 151 of the rotation output member 15, and the rotation output member 15 does not rotate synchronously; when the input When the output shaft 121 is rotated and output in the release direction of the gear case, the one-way clutch button 131 is engaged with the ring gear 151 of the rotation output member 15, and the rotation output member 15 is driven to rotate. In other embodiments, other ways than the one-way clutch clasp may be employed to achieve independent rotation between the upper chain handle and the rotary output member.

The gear box of the present invention can adopt a gear box without a switch (correspondingly, the gear box does not need to be provided with a synchronous rotating member), and the gear box is released immediately after being wound up. In the present embodiment, it is preferable to use a gear box switch. The gear box can control the gear box to maintain the accumulating force after the winding, not immediately released, and the gear box switch is used to control the release of the gear box, thereby controlling the rotation of the nozzle. The gear box switch may be an external switch or a built-in switch, or an external switch and a built-in switch are used at the same time. In this embodiment, the external switch 141 and the built-in switch 142 are preferably used at the same time, when an external switch or a built-in switch is used. When the nozzle is in the open position, the nozzle is in operation (ie, the rotary output member 15 and the rotary water outlet member 16 are rotated), and the external switch and the internal switch are both in the closed position, and the nozzle is not operated (ie, the rotary output member 15 and the rotating water outlet) Component 16 is stationary). The external switch 141 is directly used by the user to control whether the gear box is working. The built-in switch 142 controls the operation of the gear box by a user trigger by interlocking with the trigger.

The one-way stop member 18 is mounted between the gear case and an inner side wall of the second head housing rear portion 114, and includes a vertical piece 181 and a side fixed to the vertical piece 181 a horizontal piece 182; a first end of the vertical piece 181 and an inner side wall of the second head housing rear portion 114 are connected by a first spring 183, and the horizontal piece 182 is located at the vertical piece 181 and the Between the synchronous rotating parts 122 of the gearbox; when the external switch or the built-in switch enters the open position, the vertical piece 181 is directed to the second head housing under the force of the gear box switch The inner side wall of the portion 114 is moved, and the first spring 183 is compressed until the lateral piece 182 is disengaged from the synchronous rotating member 122, so that the synchronous rotating member 122 and the input/output shaft 121 are freely rotatable. When the external switch and the built-in switch enter a closed position, the gearbox switch stops applying a force to the vertical piece 181, the first spring 183 is reset, and the vertical piece 181 is at the first The force of the spring 183 moves downward in the direction of the gearbox until the transverse piece 182 is in contact with the synchronous rotating member 122, and the transverse piece 182 performs a one-way stop on the synchronous rotating member 122. The synchronous rotating member 122 cannot rotate in the releasing direction of the gear box, so that the input/output shaft 121 cannot perform output rotation; when the external switch and the built-in switch are in the closed position, the lateral piece 182 is The synchronous rotating member 122 performs only one-way stop, allowing it to rotate in the other direction. Specifically, the synchronous rotating member 122 can rotate in the winding direction of the gear box to push the horizontal piece 182 and the vertical piece. 181 is moved to complete the rotating action, and the force of the first spring 183 keeps the lateral piece 182 in contact with the synchronous rotating member 122, so that the synchronous rotating member 122 can still follow the gear box The winding direction is rotated so that the input/output shaft 121 can still perform input rotation. In other embodiments, the one-way stop member can take other shape configurations, and the first spring can also be disposed between the vertical piece and the outer wall of the gear case.

The lateral piece 182 is disengaged from the synchronous rotating member 122; when the external switch enters the closed position, the external switch moves away from the vertical piece 181, and the vertical piece 181 is from the Disengaged in the recessed position 1413, the first spring 183 is reset, the vertical Sheet 181 moves in the direction of the gear housing under the force of the first spring 183, until the sheet 182 in contact with the transverse member 122 of the rotational synchronization. In other embodiments, the external switch can take other shape configurations.
