Description of the invention (l) [Technical field to which the invention belongs] The present invention relates to a foot-type support rod pressing structure. [Previous technology] With the development and advancement of science and technology 3, people ’s requirements for things also produce the old thinking of "& just fine", which becomes quite delicate and demanding. Only the concept of continuous advancement or innovation produces new In order to improve the added value of the product and effectively reduce the cost, it can only be born under the test of RP% fierce competition ^. Attachment for reference is the patent case No. 4 5 7 9 2 2 "Telescopic and fixed pole structure improvement" patent case. It is tied to the end of the female sleeve 20 _ to form a tapered ^ mouth 21 'can stop the inner 31 end of the enlarged end 31 of the child sleeve 30 limit, and the female sleeve 2 20 = can be loaded with a section of spring 22, after the female The other end of the sleeve 20 can be combined with the two = cap 23 to limit the spring 22 in the female sleeve 20, and then the outer sleeve 40 will cover the second sleeve 40. The spring 22 can normally support the sleeve 30 and elastically extend outward. Out of the female casing, it is forced to be fixed to the walls on both sides with a supporting pin. The conventional support: Because there is no structure between the mother and child casings 20 and 30, the internal contraction of the two tr0 is used. In this way, when the force received by the mother sleeve 20 is greater than the force, the mother sleeve 20 will be retracted inside, and the support bar will lose its support. It is easy to cause accidents. This structural design is quite unsafe: Yes: what? If a harder spring 22 is used, it will lead to the difficulty of installing the support rod without pressing: the elastic spring 22 makes the female sleeve 2. Internal and contraction makes it necessary to carry out research and improvement. The various deletions derived from the tangent bar, in fact, the present invention wants to exclude or $, V to alleviate the problems encountered in the prior art

Description of Invention (3) The application is not restricted by this structure. Referring to the first figure, according to the first embodiment of the present invention, the foot-down dog support structure 1 can be stepped on by the user to effectively tighten the support rod. "Forcibly referring to the second and third figures, the foot Stepping support rod pressing structure 丨 • An outer tube 10 starting one ^ The inner tube 20, a 30 40, a foot pressing device 50, a control device 60 and the first inner tube 20 are accommodated Inside the first end of the outer tube 10. The second end of the second inner and outer tube 10 is inside. The clamping device 40 is selectively disposed on the outer tube 10, and the relative pressing device 50 between the first inner tube 20 and the outer tube 10 is provided on the second end of the outer tube 10, and can be selected. The two inner tubes 30 limit the phase between the second inner tube 30 and the outer tube 10. The outer tube 10 includes a first end and a second end. The outer tube 10 contains a space (not labeled). One end of the first inner tube 20 is accommodated in the first end of the outer tube 10 ', and the other end is provided with a stopper piece 21. The second inner tube 30 includes a first end and a second end, and a first fastening device hanging member 70 thereof. The tube 30 is accommodated at the first end and is displaced. Pedal pushes against the second pair of displacements. An accommodation space formed inside is closed at one end. It is called Xueer-Yi, the two rivers have closed ends and the valley is placed in the accommodation space at the second end of the outer tube 10. The two ends of the second inner tube 30 are provided. There is a stopper piece 31. The body of the second inner tube 30 is provided with two long holes 32 and two perforations 33 at appropriate places, and the wheel body 34 with two grooves 341 is provided in the perforation by a rod 35. 33 outer end, and the two-wheel body 34 can be rotated by the shaft of the rod 35. A stopper 36 provided with a through hole 361 transversely is disposed in the second inner tube 30, and a rod 37 is passed through the second The long hole 32 of the inner tube 30 and the through hole 361 of the stopper 36 allow the stopper 36 to slide back and forth between the long hole 32.

The quick-release handle is a quick-release structure in the C example, which can be adjusted by turning. Restricting the relative displacement between the first inner tube 20 and the outer tube 10 The mti device 5G includes a sleeve 51 and a pedal 54 at the second end of the second inner tube 3 and the outer tube 10 At the first end of the sleeve, the length of the sleeve 51 corresponding to the length of the second inner tube 30 == the coupling hole 52 is passed through the second inner tube 3. The suggestion also wears slippage: two knots ~ the outer tube 10 can also follow the stopper 36 in the axial direction 54, which is approximately π-2 and two convex posts 53 are provided at the bevel. The foot pedal ', sub 1, the distance between the two side plates is slightly larger than the diameter of the sleeve 51, the two U pieces are: the combination hole 52 is also provided with a perforation 55, the foot pedal 54: can I: the plate 嘀; the perforation 55 and the pivot It is provided on the sleeve 51, and the foot pedal 54 has a concave curved surface 56. When the foot pedal 54 is released, the two side plates abut against the convex column w of the sleeve 51. The control device 60 is a horizontally arranged pipe fitting, and the pipe fitting is placed at one end. The other end is a closed end. A long hole is provided at the proper position of the tube. An elastic body 62 and a latch 63 with a groove 631 are provided in the tube. A pin 64 passes through the long hole 61 and is coupled to the latch. The groove 631 of the post 63 can control whether the post 6 3 penetrates the open end through the lateral sliding of the pin. Refer to Figures 4 and 5 for the pressing structure of the foot support bar according to the present invention ^ In the natural state, the elastic body 38 in the second inner tube 30 is in a released state, it abuts the stopper 36 in the first position, and the elastic body 62 in the control device 60 is fully footed.
