Therefore, when the handle body 31 is in the folded position, the handle body 31 is opposite to the end of the tenon 315 for abutting against the limiting member 13. The outer circumference of the shank 31 is respectively provided with a long groove 316 at a position opposite to the two sides of the accommodating groove 311. The long groove 316 is for reducing the weight of the shank 31 while the shank 31 still has sufficient structural strength. 12 200909679 The handle sleeve 32 is coupled to the outer circumference of the handle body 31, and the handle sleeve 32 is on the handle body 31 and the convex shoulder. The outer diameter of the handle sleeve 32 is: body:: convex: 315, she is the same and concentric. The shank 32 and the shank 315 are attached to the same outer diameter. The shank 32 is provided with a through hole 321 at a position relative to the shank hole 314 for the pin to be worn. The position of the accommodating groove 311 with respect to the shank 31 is opened - the notch 32 = the lateral width of the opening 322 is larger than the width of the push rod 23, and the width is smaller than the outer diameter of the barrel U. The shank 32 has an engaging portion 323 of „_==, and the engaging portion is slightly detached from the shank (four) to be located outside the tubular body 11 to prevent the shank body 31 from pivoting. The clothing is due to the head of the wind mouth head 12. The outer circumference of the sleeve 12, the fixing sleeve 32 and the shank 31 of the shank 31 are all the same and concentric, so at 31, in the folding position, the overall appearance of the lining is _ externally pinched, with a minimalist shape The appearance of the sleeves 14 and the handle sleeves 32 can effectively resist the sun and rain, and prevent the foreign objects from directly colliding with the barrel u and the body 31, thereby achieving the effect of improving the service life. The cylinder and the shank 32 can be independently provided with the trademarks and patterns required by the customer, and the sleeve 14 and the shank 32 belong to the same pipe material, and the processing is simple, and the production cost can be reduced. More... Figure 1 to Figure 5 The grip of the grip of the present invention in the retracted position is not arbitrarily unfolded, and the rod member is not arbitrarily pulled out of the barrel u, and has a good fixing effect, and is more convenient for collecting. And it can provide a flattened overall shape with a minimalist appearance. 13 200909679 Refer to Figure VI· to pj, ^ The invention of the handle 30 is fixed in two stages with a grip 30 and the release can be directly pivoted ^/Yulong 3G (four) to the position, not looped on the barrel = It is assumed that the occlusion portion 323 of the shank 32 does not have enough elastic handles 30, so that the body is passed through the notch 322. Therefore, it is necessary to first rotate the π plucking. The fastening block 134 of the slot 33 is as shown in Fig. 6 and Fig. 7. The grip 30 is pulled out from the door line in the direction of the door 3, so that the engaging portion s of the handle sleeve 32 needs to fix the grip 30 to the cylinder. When 10 is up, it will achieve good positioning effect according to the above-mentioned object and the positioning rod 236 of the push rod 23, so the position of the unfolding position or the folding position can be achieved, and =31 and (4) are divided into 23 (4). The abutting part = _3i and the putter 23 money position can be obtained - the auxiliary j effect. As far as the above is concerned, the invention has the following advantages: 1. The invention has a T-shaped handle double-tube wall pump structure 』, providing a double-tube wall pump structure 'the outer sleeve and the handle sleeve can effectively resist the sun and rain, and can avoid direct contact with foreign objects. The body and the handle 14 200909679 body, and then achieve the effect of improving the service life. 2. The invention has the double-type overall shape of the handle, which has a flat shape and has a structure which is extremely called, and provides a sleeve and a handle sleeve. Independently processed at the same time, the external industry has strong adaptability, and the sleeve and the shank belong to the same jin: ^, 'production order, can reduce the production cost. @材原科,加工简3·The present invention "has the handle of the τ type The handle body, the barrel body and the sleeve are divided into long grooves.
