There are fixed means of telescopic structure, such as the figure-- and the second figure of the new patent case of the bulletin number "Telescopic tube positioning structure", which is based on the sigh of the two mountains and ten σ 疋The inner tube of the fixing means is still shaken after being fixed, and it is also as solid as shown in the fourth and fifth figures of the case: the means of fixing is fixed in a tight manner, although It can avoid the problem of loose inner tube. However, when the external force is pulled, the inner tube is positioned by friction, so the fragrant λ 士 η !! θ γ t , which is too large to change the length of the expansion and contraction. [New content] The fixed structure of the β, the square, and the existing garden telescopic tube is only fixed by the embedded or forced method. Therefore, it is easy to cause a fixed and inaccurate 4 M330382 point. In view of the above problems of telescopic fixing, the present invention uses the push button to cooperate with the positioning member to generate a pressing and embedding positioning effect, thereby realizing the positioning and expansion: the inner organ is used to achieve better fixing effect to provide gardening tool application. In order to achieve the above object, the present invention provides a telescopic tube fixing structure for a gardening tool, which comprises: a PI winding back and a plurality of positioning holes are arranged at intervals along the rear direction; Outside the inner tube, the positioning hole is formed on the top side of the front end portion of the outer tube to form an opening; the sleeve is $, and the sleeve body sleeve is sleeved and fixed on the outer tube shape, and the sleeve is matched The outer tube ^ , , the tooth 5 is further open, forming a road extending in the front-rear direction on both sides of the continuation port 0; a positioning member, the positioning member is in the accommodating port, 竽定#杜官 and the sleeve ^ ^ β 件 于 于 形成 形成 形成 形成 于 于 于 于 于 于 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The surface of the surface of the surface of the yoke is embedded in the locating hole, and a push button is attached to the top surface of the locating member. The lower part is convexly arranged, and further, the creation is provided on the push button, which is arranged on the track, and a push weight is protruded from the top of the plate, and the plate is slidably embedded to form a push slope, and the movable protrusion is formed. The front pressing portion for pushing the protrusion is formed on the rear side of the bottom surface of the sheet: the side plane is the sliding slope. ^ The front side of the I forced portion forms a M330382. Further, the creation is formed on the left and right sides of the sleeve opening, and the side extending in the front-rear direction, the ghost, the inner surface of each side block is adjacent to the opening. The corresponding openings on the inner faces of the side blocks are vertically recessed together with the sides of the opening - the sliding track is horizontally recessed between the two side blocks. / Good, the positioning member is provided with a pressing block, which is placed at the opening of the sleeve and is arranged on both sides of the 卩, 典, 叩 side. Each of the sliding grooves is provided with a sliding rib, and the sliding rib is slidably entrapped in each sliding groove, and the top of the pressing block protrudes from the opening. The shape of the pressing surface matches the shape of the circumference of the inner tube positioning hole and is formed thereon. The bottom surface of the pressing block is recessed in the middle of the pressing surface, and a receiving groove is arranged in the receiving groove. 'After the positioning slot is provided with a positioning '/clamping block ^ and the top end of the accommodating groove, the rear end of the locating block is made into a smaller diameter rod, with the shank The spring is formed on the bottom of the cup and the bottom edge and abuts against the bottom edge of the spring. The positioning cam is semi-circular and protrudes downward from the bottom surface of the positioning block. Li j can be used for garden tools, such as the back end of gardening shears. 'The straw provides the function of telescopic adjustment. When it is necessary to adjust the length, it pushes the m channel to slide, so that the pressing part releases the positioning piece. When the pressing surface no longer abuts against the inner tube' and because the positioning knob is not subject to the system, it can be bounced up and down. When the positioning member releases the inner tube, the inner tube can be pulled before and after, and the extension length X can be adjusted at will. During the process, each positioning hole will slide through the positioning block of the positioning block, and f... will produce the temporary clamping effect of the segment. When the telescopic length is adjusted: 1 button & the track is pushed back to the original position, so that the pressing portion is again Pressing and pressing 'At this time, the pressing surface abuts and presses the inner tube, and the positioning knob is inserted into the positioning hole of 6 M33 03 82 to complete the positioning and fixing operation.
