A hand grip is pivotally attached to the stem, a pole is secured to the hand grip and includes a lock groove, a bar is slidably attached to the housing and includes an actuator flange for selectively engaging into the lock groove of the pole, to selectively lock the pole and the hand grip to the housing. A magneto or a lock may be used for disengaging the actuator flange from the lock groove of the pole, to selectively release the hand grip from the housing.

Description

V. Description of the invention

< Technical field to which the invention belongs > The present invention is to provide a locking structure with a key that can be opened or a control frame to make it easy for a finger to reach into the trigger side of the trigger frame, and a snap-up corner latch post can be immediately driven < Prior technology > 2, Lock and electric control door buckle, Xiaobie refers to the door buckle that can be opened by 12 or 15 electronic control, its pull = leave the finger to move the space, let the user more, pull the control frame When the unlocking action is performed, it is necessary to make the trigger control J 丄 beneficial for subsequent operations, and the other is to lock the seat when the cover is closed to achieve the automatic lock effect. In order to ensure the safety of use, the door panel will be locked or can be opened at the front end of the trigger frame to insert fingers or cause injury, and after it is unlocked, the other end can only be lifted up. 'Control rack' can be easily opened by anyone. The key must be turned to prevent the serious lack of protection caused by forgetting the lock. Therefore, the applicant is applying for a product with both electronic control opening and locking functions as the first generation product.) Due to the lack of quality, we continue to develop and electronically lock the door buckle structure. "A new version of Yiyi switch box or electrical switch is installed with a door buckle on the door of the switch box. The side is set, which makes it easy to block the trigger frame when the finger is stretched in. It does not spring automatically. You must use the hand to move it. It is quite inconvenient to use. There is no locking action when the cover is closed. There is no protection ability, and the lock is used as a lock, which is inconvenient to use and allows for weight loss. In view of the existence of various conventional door buckles and the approval of the invention patent case No. 89 1 2 4854 "Lock Controlled Door Buckle Structure" (Patent ^ There are 89 89 22 applications for less controllable products during the manufacturing process.) No. 3002 「cum ^

Fifth invention description (2) Patent case (patented product is simpler and easier to operate :::; production,), Xiao's second-generation products have been praised by the industry, but, two people: characteristics of shells The spirit that has been gained after the listing continues to be developed; 玖: = and ㉟ 乃 is to keep improving < invention content> the new invention finally came out. Equipped with a lock control and unit, the center of the center, so that the unlocking action of the automatic control ^ buckle when the control lever is locked, the lever is locked, i 2, which provides a more convenient ^ Γ. The door buckle includes a trigger control unit and lock control 2 :: The lock structure is moved from the trigger frame to the finger trigger position to 2 s for easy trigger control, and the trigger control is based on automatic lift-high &, Conducive to the follow-up action, and when the if is in the first room, the latch post must first push the drive seat to retract to the quasi-drive seat, the drive seat is pushed by the elastic element and immediately post and the trigger frame, so that it is not necessary The key can achieve the effect of locking the cover of the trigger frame. < Embodiment > The present invention is to provide a designer who can lock and control both the lock control and the electric control and the door control and the electric control. Yu Yu, in order to enable him to further understand the structural design and technology of this creation, I will explain it in conjunction with the drawings later:
