[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1 - 3, a new type of telescopic handle fixing clip for a vacuum cleaner, including clip 1. The top of clip 1 is evenly penetrated with clamping holes 12, and the right side of the top of clip 1 is penetrated with a fixing hole 11. A first avoidance groove is opened on the left side of the top of clamping hole 12, and a first limiting convex plate 13 is arranged in the first avoidance groove. Second avoidance grooves are evenly opened on the front and back sides of clip 1 respectively, and the second avoidance grooves penetrate through the upper and lower sides of clip 1. Second limiting convex plates 14 are arranged in the second avoidance grooves. The second limiting convex plates 14 are designed to protrude downward, and the first limiting convex plates 13 are designed to protrude upward. Clip 1, the first limiting convex plate 13 and the second limiting convex plate 14 are integrally formed by stamping an elastic metal plate. An inner handle 31 is placed at the bottom of clip 1. A slot is opened on the right side of inner handle 31, and a chute is opened on the top of inner handle 31. The chute is communicated with the slot. Clip 1 is inserted into the slot. Card slots are evenly opened at the bottom of the slot. The second limiting convex plate 14 is clamped in the card slots. Align one end of clip 1 close to the fixing hole 11 with the slot of inner handle 31 and insert it completely. When clip 1 is inserted, the second limiting convex plate 14 will be received into the second avoidance groove under the extrusion of the slot. When clip 1 is inserted completely, the second limiting convex plate 14 relies on its own resilience to turn downward and snap into the card slot, thereby stably fixing clip 1 in the slot of inner handle 31. A connecting sleeve 2 is fixedly sleeved on the left side of inner handle 31. A counterbore is penetrated through the top of connecting sleeve 2. A threaded hole is opened at the bottom of the slot of inner handle 31. A screw 21 is rotatably arranged in the counterbore. The bottom of screw 21 penetrates through the fixing hole 11 and is screwed with the threaded hole. Connect the left side of connecting sleeve 2 with the vacuum cleaner head. Insert inner handle 31 into the right end of connecting sleeve 2 and tighten the screw 21. Fix inner handle 31 in connecting sleeve 2 through screw 21, and further press and fix the left side of clip 1 in the slot of inner handle 31 through screw 21. A sliding sleeve 32 and an outer handle 3 are slidably sleeved on the outer circle of inner handle 31. Outer handle 3 is fixedly arranged on the right side of sliding sleeve 32. The top of the first limiting convex plate 13 is attached to the top of the inner side wall of outer handle 3. A first groove is opened on the top of sliding sleeve 32. A second groove is opened on the top of the inner side wall of sliding sleeve 32. A third groove is opened on the right side of the second groove. A third avoidance groove is communicated between the first groove and the second groove. The first groove is communicated with the third groove. A pressing plate 33 is rotatably arranged in the first groove through a rotating shaft. A round head pin 34 is fixedly arranged on the left side of the bottom of pressing plate 33. A spring 35 is fixedly arranged on the right side of the bottom of pressing plate 33. Spring 35 is fixedly arranged in the third groove. The round head pin 34 is located in the avoidance groove, and the bottom of the round head pin 34 penetrates through the second groove and the chute of inner handle 31 and is inserted into the clamping hole 12. Slide and sleeve the sliding sleeve 32 together with the outer handle 3 from the right side of the inner handle 31. At this time, the first limiting convex plate 13 will be received into the first avoidance groove under the extrusion of the inner side wall of the outer handle 3. At the same time, the first limiting convex plate 13 relies on its own resilience to reversely extrude the right side of clip 1, thereby further pressing and fixing the right side of clip 1 in the slot of inner handle 31.When the pressure plate 33 is pressed downward and the spring 35 is squeezed, the round head pin 34 on the left side of the bottom of the pressure plate 33 will tilt up and separate from the clamping hole 12. At this time, the position of the sliding sleeve 32 and the outer handle 3 can be adjusted left and right. When the round head pin 34 is aligned with the clamping hole 12, the pressure plate 33 is released. At this time, the spring 35 uses its own resilience to drive the round head pin 34 through the pressure plate 33 to insert into the clamping hole 12 to complete the locking. When the outer handle 3 and the sliding sleeve 32 continue to slide to the right and the first limiting convex plate 13 is located in the gap between the round head pin 34 and the spring 35, the first limiting convex plate 13 uses its own elastic force to tilt up and press against the round head pin 34, thereby preventing the outer handle 3 and the sliding sleeve 32 from sliding off the inner handle 31.
[0021] Working principle: align the end of the card strip 1 close to the fixing hole 11 with the slot of the inner handle 31 and insert it completely. When the card strip 1 is inserted, the second limiting convex plate 14 will be squeezed by the slot and received in the second avoidance groove. When the card strip 1 is inserted, the second limiting convex plate 14 relies on its own resilience to flip downward and get stuck in the slot, so as to stably fix the card strip 1 in the slot of the inner handle 31. Connect the left side of the connecting sleeve 2 with the vacuum cleaner head, insert the inner handle 31 into the right end of the connecting sleeve 2, and tighten the screw 21. The inner handle 31 is fixed in the connecting sleeve 2 by the screw 21, and the left side of the card strip 1 is further pressed and fixed in the slot of the inner handle 31 by the screw 21. The sliding sleeve 32 is slidably connected together with the outer handle 3 from the right side of the inner handle 31. At this time, the first limiting convex plate 13 is squeezed by the inner side wall of the outer handle 3 and received in the first avoidance groove. When the locking cam 33 is in the unlocked position, the locking cam 33 is in the unlocked position, and the locking cam 33 is in the unlocked position, so that the locking cam 33 is locked.
