The present invention relates to a multi-stage prop that is used as a prop or cane of a tent, and in particular, an insert of a fastener capable of connecting an inner tube and an outer tube, wherein the lever forming the slider and the eccentric is combined and then the lever is mounted. The pusher of the slider is strongly pressed against one side of the inner tube by the operation so that the flow does not occur in the inner tube, and relates to a height-adjusting device of the multistage strut which can obtain a strong multistage strut by a firm clamping action.

In general, in order to manufacture tent props or climbing sticks in multiple stages, fixing devices should be installed at the joints of the connecting pipes forming the props.

This is to adjust the props by a certain length and then to fix them so that they can act as props.

As a conventional multi-stage holding means for fixing the inner surface of the outer tube while the inner tube is coupled to the inside between the outer side, by rotating each inner tube in one direction, the holding member of the inner tube end is rotated to press the inner surface of the outer tube. By adjusting the length of each inner tube can be fixed. Therefore, the operation to rotate and reverse rotation of each connection tube has a cumbersome and convenient problem, and also the problem that the pressure-sensitive member of the inner tube that presses the inner surface of the outer tube is easily worn and can not function properly. That is,

The purpose of the present invention to solve the conventional problems, to make it easy and convenient to fix each connector after adjusting the length of each connector, and to make a solid fixing is sufficient to serve as a prop Serve the purpose.

In order to achieve the above object, the present invention has a fastener forming a small insertion passage to which the inner tube is coupled and a large insertion passage into which the outer tube is inserted, and inserting the inner tube into the insertion portion formed between the supports of the fixture. The slider can be combined, and if the lever is provided by the pin between the supports of the fixture can achieve the object of the present invention.

Hereinafter, the present invention will be described in detail by the accompanying drawings.

First, Figure 1 is an exploded perspective view showing the configuration of the present invention, Figure 2 is a cross-sectional view showing a combined state of the present invention, a small insertion passage so that the inner tube 13 can be inserted into the upper inside of the fixture (1) (2) is formed, and a large insertion passage (3) is formed in the lower inner side so that the outer tube (14) can be inserted. In addition, a guide hole 15 is formed at one side of the upper side of the outer tube 14, such that the inner tube 13 may press the outer circumferential surface while the slider 10 is coupled to the outer tube 14. The guide tube 16 forming the opening 17 is coupled to the upper inner side so that the inner tube 13 is more closely coupled to the inside of the outer tube 14. On the other hand, an insertion portion 4 is formed between the support 5 protruding to one side of the fixture 1, and the insertion portion 4 is provided with the contact surface 11 and the ground surface 12 facing each other. Slider 10 is coupled. The pressing surface 12 of the slider 10 is inserted into the guide hole 15 of the outer tube 14 to be inserted into the large insertion passage 3 of the fixture 1, while the inner tube in the outer tube 14 (13) The outer peripheral surface can be pressed.

In addition, the eccentric portion 9 formed on the lever 7 is brought into contact with the contact surface 11 of the slider 10, so that the insertion holes 8 of the lever 7 are supported by both supports of the fastener 1 ( After matching with the plate hole 5 'of 5), when the pin 6 is engaged, the lever 7 is rotatable about the pin 6. Therefore, when the lever 7 is mounted, the contact surface 11 is pushed by the eccentric portion 9, and the pressing surface 12 of the slider 10 is moved, and the inner tube (inside the outer tube 14) ( 13) The outer peripheral surface can be strongly pressed. In addition, as shown in FIG. 4, when the two supports 5, the two sliders 10, and the two levers 7 are installed in the fixture 1 in the same configuration, a larger clamping force can be obtained.

Referring to the effect of the present invention as described above is as follows.

First, when the lever 7 is loosened as shown in the virtual line position of FIG. 2, the inner tube 13 is pushed upward or downward, or a smooth movement occurs. This is because the slider 10 which presses the inner tube 13 maintains a loose state by the release state of the lever 7. Therefore, if the inner tube 13 is adjusted to an appropriate length and the lever 7 is placed in the solid line position of FIG. 2, the lever 7 is rotated about the pin 6 coupled to the support 5 while the lever 7 is rotated. The core part 9 is in the state pushing the contact surface 11 of the slider 10, and also the slider 10 advances.

As a result, the slider 10 passes through the guide hole 15 of the outer tube 14 and the opening 17 of the guide tube 16 which are held in engagement with the large insertion path 3 of the fixture 1. The phenomenon that the pressing surface 12 of the paper presses the outer peripheral surface of the inner tube (13). Due to the clamping action of the slider 10, the inner tube 13 remains firmly fixed, and thus, the inner tube 13 can sufficiently serve as a support. When the length of the inner tube 13 is adjusted again, the length of the lever 7 is easily adjusted to the position of the virtual line of FIG.

In addition, the fastener 1 as described above is required according to the connection portion of the inner and outer tubes 13 and 14, and the volume of the inner and outer tubes 13 and 14 is reduced by wearing the same as described above. Can be used to stretch or adjust the length of the furnace.

On the other hand, FIGS. 4 and 5 are provided with the same configuration of the present invention in two places of the fastener 1, so that the inner tube 13 can be clamped by the two sliders 10. It can be used appropriately for multi-stage props.

The present invention as described above, because the lever can be fixed by clamping the inner tube by the operation, the correction means is very simple and easy, and the slider is pushed by the eccentric portion of the lever to press the outer peripheral surface of the inner tube It is possible to exert a strong clamping force by the action to obtain a strong and solid support, in particular, when applied to a multi-stage prop for tents and multi-stage cane for climbing has a very useful effect.
