[0040] Example 4

[0041] Please also read Figures 5 to 12, a quick-release device 2 provided in the fourth embodiment of the present utility model. The limiting component 226 includes a limiting member 2261 detachably connected to the second fixed seat 23 and a first elastic member 2267. One end of the first elastic member 2267 abuts against the limiting member 2261, and the other end abuts against the bottom of the first installation groove 221. The pressing component 227 includes a pressing member 2271 for driving the limiting member 2261 to move relative to the first fixed seat 22 and a second elastic member 2277. One end of the second elastic member 2277 abuts against the pressing member 2271, and the other end abuts against the bottom of the second installation groove 222. When a doctor applies a force to the pressing member 2271, the pressing member 2271 is forced into the second installation groove 222. At this time, the second elastic member 2277 is in a compressed state under the extrusion of the pressing member 2271. During the process of the pressing member 2271 being inserted into the second installation groove 222, the limiting member 2261 is driven to be inserted into the first installation groove 221. At this time, the first elastic member 2267 is in a compressed state under the extrusion of the limiting member 2261. When the doctor releases the pressing member 2271, the second elastic member 2277 releases elastic force, transmits the elastic force to the pressing member 2271, and pushes the pressing member 2271 to reset to protrude from the outer surface of the first fixed seat 22. During the process of the pressing member 2271 moving out of the second installation groove 222, under the combined action of the acting force of the pressing member 2271 and the elastic force of the first elastic member 2267, the limiting member 2261 is driven to move out of the first installation groove 221.

The abutting protrusion 2263 has a second inclined surface 2265 adapted to the first inclined surface 2274; when a doctor applies an external force to the pressing portion 2272 of the pressing member 2271 protruding from the outer surface of the first fixing base 22, the pressing member 2271 is forced to be inserted into the second installation groove 222. The pressing portion 2272 transmits the acting force to the driving portion 2273, and the driving portion 2273 squeezes the second elastic member 2277 to make it in a compressed state. During the process of the pressing member 2271 being inserted into the second installation groove 222, the driving portion 2273 is inserted into the connecting groove 2264 on the limiting member 2261, and by using the adaptation of the first inclined surface 2274 on the driving portion 2273 and the second inclined surface 2265 on the abutting protrusion 2263, the clamping protrusion 2262 of the limiting member 2261 is driven to be inserted into the first installation groove 221. At this time, the first elastic member 2267 is in a compressed state under the extrusion of the limiting member 2261; when the doctor releases the pressing member 2271, the second elastic member 2277 releases the elastic force and transmits the elastic force to the driving portion 2273 of the pressing member 2271, pushing the pressing portion 2272 of the pressing member 2271 to reset to protrude from the outer surface of the first fixing base 22. During the process of the pressing member 2271 moving out of the second installation groove 222, under the combined action of the acting force of the driving portion 2273 of the pressing member 2271 and the elastic force of the first elastic member 2267, the clamping protrusion 2262 of the limiting member 2261 is driven to move out of the first installation groove 221. The structure is simple and the operation is convenient.
