New type description: [New technical field] The present invention relates to a control rope tensioning device, in particular to a control body installed on a fixed body such as a wall and the like, and used to position a control rope of a curtain Pulling device. [Prior Art] Referring to Figures 1 and 2, there is a novel patent No. M37319 No., which discloses a fixing device i for positioning a bead chain of one of the curtains. The fixing device 1 comprises: a fixing base u having a bottom J 111, a spaced cover wall 2, a protruding from the bottom wall i 11 toward the cover wall 112 and defining a top surface An upper surrounding wall 114 of the chamber 113, a lower surrounding niche 6 located below the upper surrounding wall 114 and defining a lower chamber 115, and a beaded passageway 1 between the upper and lower surrounding walls 114, 116 7, the upper surrounding wall 4 has an upper notch 118, and the lower surrounding wall 116 has a lower notch ι9 corresponding to the upper and lower notches 118, and the bottom wall ill has an assembly hole corresponding to the upper chamber 113. 11〇. The conventional fixing device 1 further includes an upper limit member 12, an assembly hole 11 passing through the upper limit member 12 and the fixing seat U, and an upper fixing member 13 screwed on the wall, and a lower pressing position. The elastic member 14 of the piece 2, a lower limit member 15, and a lower member 16 for screwing the fixing base u and the lower limit member 15 together on the wall. The upper limit member 12 has an upper projection 丨21 corresponding to the upper notch 118, and the lower limit member 15 has a lower projection 151 which passes through the lower notch 119 and is elastically pressed against the bead chain 1〇. When the conventional fixing device 1 is not mounted on the wall, it is subjected to the selection of the elastic member 14 'the upper portion 12 of the upper limit member 12 protrudes into the bead key 1C 117 and is inserted in the bead key Between the two beads of 1Q, the lower dog portion 151 of the lower limit member 15 also protrudes upwardly toward the bead chain passage 117, and is interposed between the two beads of the bead chain 10 to prevent the bead chain. mobile. When the user wants to mount the fixing device 1 on the wall, the upper fixing member U is first passed through the upper limit member 12' and then the upper limit member 12 is pulled up against the elastic force of the elastic member 14 to make the upper fixing member The end of the end of the bottom wall (1) can be screwed onto the wall. After assembly, the protrusion 121 on the upper limit member 会2 can be retracted into the upper notch 118 of the fixing seat u. The latching of the bead chain 10 is released, and the lower fixing member 16 passes through the lower limit member 15 and the fixing seat 1! The rear screw is screwed on the wall, and the lower limit member 15 is pushed backward after screwing. The lower protrusion j5 j and the bead key are disengaged from the cassette 'At this time, the bead chain is free to move. Although the above-mentioned novel patent can limit the end of the bead chain 1G to the wall, the structure needs to be mounted using the upper and lower fixing members 13, 16, so that assembly is a little troublesome. On the other hand, although the aforementioned novel patent utilizes the elastic member 14 to support the upper limit member 12, the elasticity of the upper limit turn 12 is only used to position the bead chain 1()' when the upper and lower fixing members 13, 16 are screwed. After the lock is applied to the wall, the fixed seat 11, the upper limit member 12 or the lower limit member 14 are fixed to the wall, that is, the bead chain 1G does not have any series of elasticity. The above structure sometimes causes the bead chain 10 to be too tight and unsatisfactory after installation, sometimes because the fixing device has a high mounting height, or the bead chain 10 is loose after use for a period of time. In the case of Matsuzaka, not only the bead chain 10 is easy to cause sound due to the wind blowing into the wall, but also the potential problem of the bead M422932 chain ίο being played by the young child around the neck. [New content] The purpose of the present invention is to provide a control rope stretching device for a curtain that can improve the safety of use of the control rope and smooth operation.
