In the present embodiment, if accumulator out of power or electric power are insufficient, and the replacement of the not no accumulator of user
Or forget to replace, then safety belt can be locked manually using retaining mechanism and drawstring.In use, utilizing retaining mechanism
Reeler is limited, that is, prevents safety belt from can not be pulled out out of reeler.Then user catches the end of drawstring, by
Lantern ring is passed through in safety belt, drawstring is pulled out, drawstring drives lantern ring to be displaced outwardly, and is tightened safety belt using lantern ring,
It can ensure the normal use of safety belt in this way.Wherein, band adjuster is released when pressing pressing piece by the setting of spring
Pressure when, due to the restoring force of spring, lantern ring can be restored to original position by spring, that is, safety belt is withdrawn into seat portion
Inside is convenient for reeler to safety belt wind or loosen safety belt in this way.
Shown in Fig. 3~5, the retaining mechanism is spacer pin 22, and the side of the holder 7 is equipped with a through-hole 23, institute
The outer edge surface for stating the side of shaft 8 is equipped with a plurality of limit holes 24, and 24 annular of a plurality of limit holes is distributed in the shaft 8
On outer edge surface, the limit hole 24 and spacer pin 22 are set to the opposite side of the motor 9, and the movement of the spacer pin 22 is inserted in
In the through-hole 23, the spacer pin 22 can be inserted in a limit hole 24.Wherein, if spacer pin 22 is inserted into
Into limit hole 24, when safety belt is tightened pulling by such drawstring by lantern ring, due to spacer pin and limit hole countershaft
Limit, such shaft can not move, that is, safety belt can not be pulled out out of reeler, just be merely able to pull support portion front end
Safety belt, that is, safety belt is tightened.
Shown in Fig. 3~5, it is additionally provided with snap-gauge 25 and positioning column 26, the positioning column 26 is parallel to the shaft 8 and sets
It sets, the positioning column 26 is set on the holder 7 of 9 opposite side of the motor, the middle part of the snap-gauge 25 and the positioning column 26
It is rotatedly connected, the front side of the snap-gauge 25 and the outer end of the spacer pin 22 are rotatedly connected, and rotate the snap-gauge 25, the snap-gauge
25 can drive the spacer pin 22 to be inserted into the limit hole 24 or pull out the limit hole 24.
In the present embodiment, under normal circumstances, snap-gauge is vertically arranged with positioning column, and such spacer pin is in the outer of limit hole
Portion, wherein limited post is arranged in the front side of positioning column, rotates snap-gauge, snap-gauge around positioning column rotation, make the front end of snap-gauge towards
Shaft pushes, and the rear end of snap-gauge utilizes snap-gauge to push spacer pin, spacer pin can be made to be inserted into so then towards movement outside shaft
Into limit hole, the limit of shaft is realized, realize the locking to reeler, ensure that drawstring can normally draw safety belt
Tightly.
In the present embodiment, in the state that motor can work normally, user can also move snap-gauge, make spacer pin
It is plugged in limit hole, this makes it possible to limit reeler, safety belt is prevented to be drawn out, can also prevent safety belt quilt
It tenses, even if the case where maloperation occur in children, safety belt will not be pulled, and ensure the safety used.
