Description of the invention: [Technical field to which the invention pertains] The invention mainly discloses a type of draping aid, especially an easy-to-adjust tool for adjusting the size of the opening. [Prior Art] Refer to China Patent Certificate No. D123939 "Nail Puller", which has a complete and unnotched nail puller surface, which is inserted between the nail and the nail by a flat nail puller surface. ,. Pour the nails. The nail puller has only the front end part and the nail lion, which cannot be used as a force surface, and is not suitable for use in situations where a large force is required to open the nail. #照 China Patent Certificate No. M315635 "Replaceable nail pull structure", which includes several kinds of nails with different notches. It can be used by the latter. Suitable nail puller extends the gap under the nail head By having a large contact area with the nail head and a larger force applying surface, the nail can be easily skibed. However, this alternative nail pull structure has not been favored by users. Users must have a variety of different sizes of nail pullers, with different sizes of nails and different pull rods. The design of the shank for different sizes of nails does not provide the user with quick use and is not a convenient design, and there is a need for improvement. The present invention therefore intends to obviate or at least alleviate the problems encountered in the prior art. SUMMARY OF THE INVENTION 201020074 The technical problem of the present invention is to provide a broadcastable tool that provides an easy-to-use broadcast tool. The main effect of the drawing is that the size of the opening can be adjusted by two relatively movable parts.槪 This month's month - the person has to achieve the effect, there is a positioning between the camera and the handle, the splitting of the plucking of the handle. Ben, the monthly X achieves the effect that the positioning device only needs to be simply pressed or rotated to control the movement of the aid member, and the operation is quite simple. Ο 【Embodiment】 The technology, means and Wei of the riding method are described in the following, and the details are as follows. This is for the purpose of use only. Structural limitations. The sound reference picture -' is outside the domain of the first practical example of the extraction tool which can adjust the opening σ size. The raking tool of the present invention purely contains two sled pulls 〇 grip 2a and two positioning skirts 3a. The two pull members 1 are provided with a pull-out tilting and two sled pull-out members to cover the handle %, and the two pull-out members are relatively far apart or close to each other, and the two turns are located at the grip 2a. & fine by the shouting device, such as the meeting will be according to the map, this is the first time
