In the present embodiment, the installation, use and advantages of the adjustable spring portion 303 are as follows.
Firstly, during initial installation, the radial plate 303f is clamped by a clamp, then the connecting rope 304c sequentially passes through the rope passing hole 303g, the rope embedding groove 303r and the rope clamping hole 303h, and then the integral body of the loosening holding ring 303b and the rope fixing ring 303d is rotated, so that the connecting thread 303k starts to be screwed, and is rotatably screwed to the radial plate 303f to press the radial plate clamping ring 303q, so that the four parts of the loosening holding ring 303b, the rope fixing ring 303d, the radial plate 303f and the connecting rope 304c are formed into an integral body, and the elastic force of the jacking spring 303c can be finally converted into the pressing force of the elastic ring 302e on the lower surface of the positioning platform plate 14.
Secondly, when the slide positioning block 2 needs to be slid in use, the loosening grip ring 303b is pushed towards the inverted L-shaped duct 304a, the principle is that a part of the elastic force of the jacking spring 303c is shared by the 'hand', the pressing force of the elastic ring 302e is naturally small, the friction force is also small, the slide positioning block 2 can be slid, the loosening grip ring 303b is loosened, and the jacking spring 303c naturally tensions the connecting rope 304c, so that the movable limiting rod unit 3 enables the slide positioning block 2 to have a normal state of natural clamping and fixing and a function of conveniently releasing clamping.
Thirdly, the size of the opening of the rope clamping hole 303h is relatively small, so that when the connecting thread 303k is screwed, the connecting rope 304c cannot fall off from the rope clamping hole 303h, and the connecting threads 303k at the two positions can further clamp the connecting rope 304c, thereby further strengthening the clamping action.
Fourthly, the screwing action between the radial plate 303f and the rope body fixing ring 303d cannot be established without the radial limiting action of the limiting block 303p, and therefore, the limiting block 303p is engaged with the limiting groove 303m to ensure effective screwing between the radial plate 303f and the rope body fixing ring 303 d.
Fifth, the movable fixing structure of the connecting rope 304c at the rope clamping hole 303h can adjust the effective length of the connecting rope 304c, so that if the elastic force of the jacking spring 303c is reduced along with the extension of the using time, the effective length of the connecting rope 304c is correspondingly reduced, and the connecting rope can be used normally, which is very efficient and economical, and the jacking spring 303c is not required to be replaced frequently.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
