Abstract

The present invention relates to a securing device for retractable elliptic tube, comprising a non-circular tube with an end to which a rotation knob is coupled and an opposite end over which an outer tube retainer, an outer tube fixed to the outer tube retainer, a movable member, an inner tube retainer and an inner tube fixed to the inner tube retainer are sequentially fit, wherein the movable member is driven by the non-circular tube to rotate and corresponding thereto, the inner tube retainer forms at an end corresponding to the movable member a clamping section. The clamping section defines a conic bore and correspondingly, the movable member forms a conic section, which allows the movable member to be axially movably received in the clamping section of the inner tube retainer with the conic section abuttingly engaging the conic bore of the inner tube retainer to force the clamping section to abut against inner surface of the outer tube to effectively achieve the functions of positioning and securing and extending life span of the securing device.

200521342 V. Description of the invention (1) '[Technical field to which the invention belongs] The present invention relates to the technical field of a telescopic oval tube, such as the handle of a flower scissors ... Positioning device for telescopic elliptical tube. [Prior art] The positioning device of the telescopic elliptical tube is generally known, as shown in Fig. 9 to Fig. 11, which includes a rotatable base 60, and a polygonal column 6 is fixedly fixed through the center of the base 60. 1 and an outer pipe fixing seat 62 is pivotally provided on the top of the base 60, and the outer pipe fixing seat 62 can be sleeved with an outer pipe 6 3 for the polygonal column 61 to penetrate the outer pipe 6 3, and A linkage seat 6 4 is provided in the outer tube 6 3, and the linkage seat 64 can be rotated by the polygonal column 61, and an eccentric block 65 is provided in the middle section of the linkage seat 64. The eccentric block 6 5 can An eccentric wheel 6 6 is provided, and an inner tube fixing seat 6 7 is pivotally provided at the top of the linking seat 6 4, so that the inner tube fixing seat 6 7 is fixedly provided with an inner tube passing through the outer tube 6 3. 6 8; By rotating the base 60, the interlocking seat 64 can be rotated, so that the interlocking seat 64 can interlock the eccentric block 6 5, drive the eccentric wheel 6 6, and eccentric the sides of the eccentric wheel 6 6 The convex part is forced against the inner wall surface of the outer tube 63, and is formed in a two-axis pressing manner. However, the conventional positioning device of the telescopic elliptical tube still has its defects. Therefore, in the implementation of the use, due to the eccentric wheel pressing method, the entire system is simply forced to support the inner tube surface of the outer tube with the axis protruding from both sides. Positioning, and after prolonged use, the two protruding parts of the eccentric wheel are easy to wear with the inner wall surface of the outer tube, forming a slip phenomenon, and easy to lose after a period of use

Same, and the main end is cut through with a certain seat 7 2 The inner tube is fixed to penetrate the support block 7 6 However, the long side of the difference is not close to the internal problem of the forced support block, forming the same effect as the outer tube and the positioning effect of the invention (2), and it is easy to cause the above-mentioned expansion and contraction. The binding must be provided with a wide base on the surface. 7 The outer tube simply relies on two axes at the contact position. The longitudinal elbow of the telescopic elliptical tube is approximately the same as the previous rectangle. The inner tube 7 7 has a through hole 7 5. The line is the same as the conventional side column of the simple and loose easy position setting device, and the inner tube of the fixed seat is fixed, and the inner wall of the outer tube of the through hole 7 has only the deviation. Causes the movement and loosening, such as the first eccentric 70, and the polygon 7 2 and one side contact the two positions of the heart wheel. The market picture 2 and the positioning of the polygonal column 7 0 are fixed to the fixed seat 7 4 and a knot. The inner tube is fixed to both sides of the 5 and its side shaft is not well connected. In addition, the thirteenth thunder-shaped column 7 is sequentially fixed to the outer tube and is fixed to the seat 7. The bottom side of the 4 is provided with a forcing mentioned above, which can be easily loosened by rotating on the two outer tubes. Content] The main advantage of the Ming and the positioning device is to turn the base and the inner side of the two supporting blocks, which are not related to the polygon problem. Therefore, it cannot be effective. The main purpose is to use a long-life system to directly move the polygonal column by the length and width of the polygonal column, so that the inner surface of the polygonal column can be divided outside the two forcing blocks, but under long-term use, there are still two columns and After a period of use, the friction between the inner wall surface of the outer tube is tight, and the two force-bearing blocks are pressed tightly, resulting in the inability to effectively locate. In order to solve the above problems, a positioning device for a telescopic oval tube is provided.
