[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1 - 3 The utility model provides an embodiment: a fixing pin that is easy to adjust and use, including a pin body 1, and a fixing mechanism 2 is provided on the inner wall of the pin body 1; the setting of the fixing mechanism 2 can achieve the purpose of quick installation and positioning, thereby avoiding the need for additional parts for installation, and the fixing mechanism 2 includes a moving column 208, the outer wall of the moving column 208 is slidably connected to the inner wall of the pin body 1, and the sliding of the two makes the moving column 208 only able to move in the vertical reverse direction, and the moving column 208 will not separate from the pin body 1, and the top of the moving column 208 is fixedly connected to the support block 201, and the movement trajectories of the two are the same As a result, the inner wall of the pin body 1 is elastically connected to the plug-in block 202 through the connecting spring 203. There are two groups of plug-in blocks 202, and they can only move horizontally. The bottom end of the movable column 208 is fixedly connected to the movable plate 206, and the inner wall of the pin body 1 is slidably connected to the movable column 205. The two groups of movable columns 205 can only move horizontally and will not separate from the pin body 1. The top of the movable column 205 is fixedly connected to the connecting column 204, and the moving trajectories of the two are consistent. A quick release mechanism 3 is provided at the right end of the pin body 1. By setting the quick release mechanism 3, the purpose of quickly removing the pin body 1 is achieved.

[0031] Reference Figures 1 - 3, one end of the connecting spring 203 is fixedly connected to the outer wall of the plug block 202, the other end of the connecting spring 203 is fixedly connected to the inner wall of the pin body 1, the outer wall of the plug block 202 is slidably connected to the inner wall of the pin body 1, and the elastic force of the connecting spring 203 enables the plug block 202 to have the functions of reset and limit. One side of the plug block 202 facing the moving column 208 is inserted into the inner wall of the support block 201, and the two are inserted to limit the protruding state of the movable column 205. One side of the plug block 202 facing the moving column 208 is inserted into the inner wall of the moving column 208, and the two are inserted to limit the received state of the movable column 205. An inclined groove is provided on the outer wall of the movable plate 206, and the inclined groove is provided to enable the two connecting columns 204 to move synchronously. The connecting column 204 is T-shaped, and the T-shaped setting prevents it from detaching. The top end of the connecting column 204 contacts the inner wall of the movable plate 206, and the two contact to drive the connecting column 204 to move through the movable plate 206. The top end of the plug block 202 is provided with an inclined surface, and the inclined surface is provided to facilitate the downward movement of the moving column 208 for quick limit fixation.

[0032] Refer to Figures 1 - 3 , the quick release mechanism 3 includes a slider 301, the outer wall of the slider 301 is slidably connected to the inner wall of the top end of the pin body 1, the slider 301 can move horizontally and will not detach from the inner wall of the pin body 1. A support plate 302 is rotatably connected to the left end of the slider 301, and the support plate 302 plays a connecting role. The left end of the support plate 302 is rotatably connected to the right end of the plug block 202, and the two rotations avoid movement interference and drive the plug block 202 to move through the support plate 302.

[0033] Working principle: When it is necessary to use the pin body 1 for fixed positioning, at this time, insert the pin body 1 into the corresponding slot hole, and then move the support block 201 downward, so that the support block 201 drives the movable plate 206 to move downward, and then the two connecting columns 204 drive the two movable columns 205 to move towards both ends, so that the two movable columns 205 are unfolded to achieve fixation. At the same time, when the moving column 208 moves downward, it will contact and squeeze the inclined surfaces of the two plug blocks 202, so that the two plug blocks 202 move towards both ends. When the moving column 208 moves to the bottom, at this time, the two plug blocks 202 are inserted into the support block 201 to complete the limit fixation. The operation is simple and convenient. And when it is necessary to make the pin body 1 detach, move the slider 301 inward so that the two support plates 302 drive the two plug blocks 202 to move outward, so as to release the limit of the plug block 202, and at this time, the pin body 1 can be removed. The operation is simple and convenient.
