New description: [New technical field] The case is about the structure of crutches (including long rods such as trekking poles), especially the improvement of the composition of crutches. [Prior Art] Crutches are important tools for the elderly or those who are not good at walking or moving the body. They are mainly used to support the weight of the body and other components. The above-mentioned crutches are mainly composed of a head body for providing a hand grip and a longitudinal cylinder. The shape and structure of the head body for holding the hand are cumbersome, and it is not easy to be associated with the longitudinal column. The whole body (the whole structure) is mass-produced, so it is generally manufactured separately and then combined. As shown in the first figure, a structural cross-sectional view of a conventional crutches is provided; a concave hole C and a convex end D are respectively disposed between the head body A and the longitudinal cylinder B, so that the concave hole C and the tip D are combined with each other, and the adhesive is used. Bonded at the joint position. Since the use and force of the crutches are not static, in the case of external force or improper force or material problems, the head body A and the longitudinal cylinder B are often easily damaged, and when the bad or bad combination is used, Crutches can be harmful. [New content] The main purpose of the present invention is to provide a structural improvement of the crutches, especially the reinforcing knot provided on the outer side of the joint position between the head of the crutches and the longitudinal cylinders M321780. The joint position of the crutches head and the longitudinal cylinder is referred to above. The outer side of the outer side is provided with a hollow official body, so as to close the position which is easy to cause damage, so that the position can be prevented from external force or deformation before damage, and the protection function can be achieved. The above-mentioned hollow tubular body can be made of metal, The material such as plastic is not only practical but also aesthetically pleasing. [Embodiment] ► As shown in the second figure, the present invention is mainly configured to provide a tube body on the outer side or near the longitudinal body 20 of the crutches. 3. The pipe body 10 is mainly provided with a structure for holding the hand and transmitting the force, and includes a grip portion U for providing a hand grip and a connecting portion 12 coupled to the longitudinal cylinder 20. The shape of the pipe body 10 as described above is not limited to the one shown in the drawings, and may be a conventional shape such as a hook-shaped handle or a columnar shank, as long as it is suitable for holding the hand and transmitting the force. Longitudinal The cylinder 20 is a column body having an appropriate length, and the proper length is suitable for the length of the column body capable of providing a conductive support force or the like when the user is a cane, and may be a preset fixed length, or may be The adjustable length of the telescopic handle structure may be any. The pipe body 30 is arranged in a hollow tubular shape at the outer side of the joint position of the head body 10 and the longitudinal cylinder 2〇, or the hollow inner portion of the pipe body 3〇 is connected to the joint portion. 12. Insertion of the longitudinal cylinder 20 or both. As shown in the third, fourth and fifth figures, the state diagram of the decomposition and combination of the connecting portion 12, the tubular body 3〇 and the longitudinal cylinder 20; the connection in the figure The combination of the portion 12 and the longitudinal 6 M321780 to the cylinder 20 is the same as that of the conventional method (herein, not limited to the combination of the drawings), and a recessed hole 121 is provided on the lower side of the connecting portion 12, in the longitudinal cylinder 20 A protrusion 201 is disposed on the upper surface, and the protrusion 201 is placed in the recessed hole 121 and glued by adhesive or the like to form a joint; in the present case, the upper end 202 of the longitudinal cylinder 20 is disposed to be sleeved by the tubular body 30. In the state, the tubular body 30 can tightly surround the upper end 202 of the longitudinal cylinder 20. The upper end 202 of the longitudinal cylindrical body 20 of the tubular body 30 can make the upper end 202 of the so-called Qin longitudinal cylinder 20 less susceptible to damage or deformation. As shown in the sixth figure, the connecting portion 12 and the upper end 202 of the longitudinal cylinder 20 are shown. And another embodiment of the combined state of the tubular body 30, wherein the tubular body 30 is encircled around the lower outer side of the connecting portion 12, and has a joint position of the connecting portion 12, the upper end 202 of the longitudinal cylindrical body 20, and the like. The function of causing damage or deformation. As shown in the seventh figure, a further embodiment of the present invention is a state in which the tubular body 30 surrounds the connecting portion 12 and the upper portion of the longitudinal cylinder 20, wherein the connecting portion 12 is The longitudinal cylinder 20 is not formed with a recess, and the tubular body 30 may be disposed on the outer sides of the two. Depending on the encircling position of the tubular body 30 shown in Figure 7, the tubular body 30 can be only encircled by the longitudinal cylinder 20 or the connecting portion 12, which is also within the scope of the present patent. The disclosure of the present invention is a preferred embodiment, and it is easy for a person who is familiar with the skill of the present invention to change or modify the subject matter of the present invention.
