Post (1 = line (10)): two of the control The ends are connected to the control handle (10) and the push rod fixing sleeve (03); the fixing sleeve is provided with a hole (10) and an ear portion (31), and the basin one hole (33) is sleeved on the auxiliary body (5) The ear (8) is also attached with a through hole (32), and the control handle (10) is fixed to the through hole (32) by the pin (04). ❹ ♦ ♦ The puller body has a foot portion The lower end of the foot bar has a correspondingly arranged joint 4 (02), and a joint (21) is arranged on the joint portion. The inner sleeve (08) has a hole (8) inside. And set at the bottom end of the auxiliary leg (〇7) to prevent the walker from slipping with the ground during use. On the lion cut (10) rod, set a number of positioning holes parallel to the rod and set u-type The groove (72) is provided with the purpose of the ϋ-shaped groove to avoid the rotational movement of the auxiliary leg, and the contact ((4) plucking _ an appropriate length to avoid the insertion of the pin. The bottom end of the above-mentioned joint sleeve (09) An outer edge groove (10) is disposed on the outer edge groove, and a movable hole (94) is disposed on the outer edge groove, thereby providing a hole for inserting the pin (14); and another fixing hole (10) is disposed on the ear portion of the joint rod sleeve (95) On the upper side, the push rod (13) is fixed to the fixing hole (93). The upper end (134) of the push rod (13) is provided with a hole (132), and the control line is provided. (10)) is fastened at an appropriate angle between the upper end portion (134) and the 杆-shaped rod portion (133), and a fixing hole (131) is disposed between the upper end portion (134) and the ϋ-shaped rod portion (133). The pin (11) is inserted into the fixing hole (93) of the engaging rod sleeve ear portion (95) so as to make the push rod (13) actually move and move to force the borrowing portion (133) and the latch (14). Sales on the market (12) The purpose of sliding each other is to provide a groove (14ι) on the plug (14) and to place the elastic member (〇8) therein. The pin end is provided with a hole (142) and is pinned (12). Insert the solid to provide the purpose of 8 200938181 sliding push. The above control handle (〇5) is provided with a hole (53), the hole (53) is connected with a control line (06), and the rear of the hole (53) is at an appropriate distance. An ear portion is disposed, and a hole (52) is disposed on the ear portion. A hole (33) is disposed on the fixing sleeve (03), and the hole (33) is sleeved at a proper position of the walker body (01). A hole (32) is additionally provided on the ear (31) of the fixing sleeve. The related components mentioned above are set as shown in the second figure. 〇 ❹ The mechanism actuation mode mentioned above is shown in Figures 3 and 4, with the control handle (05) as the input and the positioning pin (14) as the output. In its control mode, first press the control handle so as to be affected by the control line (〇6), the control line (〇6) is on the push rod-hole (10), and the wire is missing ((3) the hole on the upper end of the rod (132) ) 'causing the push rod (13) to make a rotary motion' by this rotation to cause the U-shaped rod portion (133) at the lower end of the push rod (13) and the pin (12) on the positioning pin (14) to produce a sliding motion 'by sliding Push to pull out the positioning pin to the hole (7丨) on the auxiliary leg (〇7) for an appropriate distance, so that the auxiliary leg (〇7) is originally fixed to the walker body (〇1). The joint ^(02) (as shown in the third figure) is further changed to the non-fixed state (as shown in the fourth figure)' and the state is further adapted to adjust the auxiliary leg (10) relative to the walker body (01) The length of the rod between the joints (02) (as shown in the fourth figure), and vice versa; if it has been determined that the auxiliary foot (07) is adjusted to the required telescopic length, and the original is applied to the control handle (05) After the upper applied force is removed, the positioning pin (14) is pressed into the hole (71) on the auxiliary leg (07) by the elastic member (1〇), and the fixing is changed to the state of For the purpose of positioning the pole length, Therefore, the present invention achieves the purpose of the design by the above actions. The purpose of the above-mentioned design of the present invention can be referred to the fifth, sixth and seventh figures; the forward direction of the walker body (G1) is regarded as the front, and vice versa. The walker body (5) is regarded as the rear direction using the forward and reverse directions; if the front walker body (07) is retracted into the walker body joint portion (10), the length of the phase between the shortening is shortened' Further, the auxiliary auxiliary foot (10) is pulled out of the walker body joint portion 9 200938181 (02) to cause the relative length between the elongated rods to assist the user to travel on the stairs above the stairs, as shown in the fifth figure. As shown, if the auxiliary body (〇1) in front of the walker body (〇1) is pulled out of the walker body joint (〇2), the relative length between the extensions is made, and the walker is again The rear auxiliary leg (〇1) is retracted into the walker body joint (02) to shorten the relative length between the legs to assist the user in traveling ^ the stairwell downstairs, as shown in the sixth figure In addition; if the walker body (〇1) is then pulled out of the auxiliary body (07) The joint (〇2) causes the relative length between the elongated rods and the other auxiliary body (〇1) in front of an auxiliary leg (〇7) of the walker body joint (〇2) to cause a shortening between Relative to the length of the rod, the auxiliary leg (〇7) behind the walker body (01) is retracted into the walker body joint (02) so that the relative length between the shortening is long and the other rear is an auxiliary branch. The foot (〇7) pulls out the walker body joint (02) to cause the relative length between the elongated rods, or any of the auxiliary legs (〇7) and the walker body joint (〇2) Appropriate relative rod length between them to assist the user in traveling to various applicable non-planar grounds, as shown in the seventh figure, for avoiding the auxiliary leg (07) in the walker body joint (〇2) The problem of the rotation causing the locating pin (14) to be inserted, in addition to the proper length of the locating pin (14) in the groove (72) of the auxiliary leg, can be achieved by other methods. As shown in the ninth figure, a set of barrels (7 inches) can be additionally provided on the joint body (02) of the walker body, and the inner diameter of the sleeve (70) is set to protrude. (7〇1 '), and the projecting block (701) to fit to avoid the occurrence of the above (72) feet of trench-assisted. Month / Adjust the length of the auxiliary leg (07) relative to the body of the walker body (〇2) for the above, except that the user can press the walker body (01) or borrow the heart or borrow any part of the body Applying a force to the auxiliary leg (07) to adjust the length of the outer leg can also be used to install a spring (80) on the auxiliary leg (07) to facilitate adjustment of the relative rod length, as shown in the tenth figure. For the above-mentioned rotary motion by the push rod (13), and by this rotation, the U-shaped rod portion (133) at the lower end of the push θ (13) and the pin (12) on the positioning pin (14) are slipped. In addition to the mode, it can be achieved by other means. As shown in the eleventh figure, the shape of the push rod (13) is fixed, and the u-shaped rod portion (133) is changed to the flat shape (13a)' and will be positioned. An opening groove (14a) is arranged in the direction of the hole (丨42) of the pin (丨4), and the end of the push rod (13) is inserted into the opening groove (for example, behind the hole 42). A mode in which the lower end rod portion (10) of the push rod (10) and the pin (10) are caused to slide. For the above-mentioned foot cover (08), except for a hole (81), the outer shape is a long strip type, as shown in Figures 12 and 13. 'The walker and the ground are made by the elongated foot cover (10) a)
