A bottom end of the fixing hook 4 is a push-button part 44; the push-button part 44 is in the form of a block with an arched surface. An inner side surface of the push-button part 44 is provided with a recess, and a middle part of the fixing base 3 is provided with a corresponding protruding post 32; a spring 5 has one end fitted over the protruding post 32 and another end supported in the recess, so that the push-button part 44 has the tendency to always spring outwards and drive the hook part 41 of the fixing hook to turn inwards and abut a front end of the fixing base 3. The hook part 41 of the fixing hook 4 has a right-angled hook surface with an inclined surface at a top end; the engaging slots 221 are square slots which match the right-angled hook surface. A bottom end of the limiting slide strip 22 has an inclined surface which facilitates engagement of the hook part 41; thus when the handle 2 slides down into the proper position, the hook part 41 of the fixing hook 4 is pushed up by means of the inclined surfaces, the limiting slide strip 22 slides into the bottom such that the hook part 41 falls down and engages in the engaging slot 221 of the limiting slide strip 22 to lock the handle 2, and since the pressure borne by the right-angled hook surface of the fixing hook 4 is offset with respect to the pin hole 43, the fixing hook 4 is made to deflect downwards after being subjected to force in this way, to prevent detachment. Since the design has two engaging slots 221, it is possible to switch positions, so as to adjust the tightness of the canopy. A fixing cover 6 is provided outside the slide groove 11 of the middle rod 1 in a fitting manner in a position corresponding to the fixing base 3; a middle part of the fixing cover 6 is provided with a square opening 61 for the push-button part 44 of the fixing hook 4 to project through; a front end of the fixing cover 6 is provided with a gap 63, which corresponds to the slide groove 11 and allows the top end of the fixing hook 4 to turn.

The fixing base 3 is fixed in the slide groove 11 by passing a screw 8 through the sunken mounting hole 62, the connecting hole 33 and the locating hole 12 and locking the screw with a matching nut 100 at the other end. Two ball-head bayonets 34 are also provided at a tail part of the fixing base 3, for engaging a lever 7 (an umbrella accessory, used during assembly). A handle cover 23 is provided in a fitting manner on the handle base 21; a tail part at a top end of the handle base is provided with a slot hole 213, and a tail part of the handle cover 23 is provided with a corresponding barb. A middle part of the handle base 21 is provided with connecting post holes 211, and corresponding connecting screw holes 231 are provided on an inner side of the handle cover 23; the two are connected in a fixed manner by screws 9. Moreover, two projecting points 232 are provided in the handle cover 23, and mate with two corresponding round holes 212 provided on the handle base 21, to prevent the handle cover 23 and handle base 21 from opening up after assembly.

The specific assembly steps are as follows: 1. The handle base 21 and handle cover 23 are fitted together using screws 9 to form a grip component, and mated with the slide groove 11 of the middle rod 1 by means of the limiting slide strip 22 so as to slide up and down. 2. One end of the spring 5 is pressed into the recess in a tail part of the fixing hook 4, the other end is fitted over the protruding post 32 in the middle part of the fixing base 3, the connecting part 42 with the pin hole 43 in a middle section of the fixing hook 4 is pressed into the fixing slot 35 at the front end of the fixing base 3 and then the fixing pin 10 is inserted, and the hook part 41 at a front end of the fixing hook 4 always abuts the front end of the fixing base 3 under the pressure of the spring 5. 3. The fixing base 3 in which the fixing hook 4 was mounted in step 2 is slid in along the slide groove 11 of the middle rod 1, until the connecting hole 33 in the tail part of the fixing base 3 is aligned with the locating hole 12 in the slide groove 11; the fixing cover 6 is aligned with the fixing base 3 and pressed onto the middle rod 1, the sunken mounting hole 62 of the fixing cover 6 is aligned, and the screw 8 is inserted; the screw 8 is passed through the sunken mounting hole 62, the connecting hole 33 and the locating hole 12, and at the other end, the nut 100 is aligned therewith and then tightened using a tool. 4. The lever 7 is slid in along the slide groove 11 of the middle rod 1 up to the tail part of the fixing base 3, and engaged between the two ball-head bayonets 34 with a slight effort, to accomplish accommodation of an accessory. 5. When assembly is complete, the handle 2 is pressed down until a tail part of the limiting slide strip 22 contacts the hook part 41 at the front end of the fixing hook 4, at which time the inclined surface at the tail part of the limiting slide strip 22 pushes up the fixing hook 4 so that the hook part 41 at the front end thereof is raised; the tail part push-button part 44 is pressed down and compresses the spring 5 tightly, the handle 2 continues to be pressed down and the hook part 41 of the fixing hook 4 partially slides into the engaging slot 221 of the limiting slide strip 22 and hooks onto it; since the right-angled hook surface of the fixing hook 4 is offset with respect to the pin hole 43, it forms a downward offset force when subjected to tension by the handle 2, and can effectively prevent loosening of the fixing base 3. 6. The push-button part 44 at the tail end of the fixing hook 4 is pushed lightly, so that the hook part 41 at the front end thereof is raised and separated from the engaging slot 221, and the handle resumes sliding.

During use, all that need be done is to grip the handle 2 in the hand in order to slide it up or down to drive the umbrella to open or close; the push-button part 44 of the fixing hook 4 enables the umbrella to be closed by just pressing lightly, which is fast and comfortable.
