[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of the technical solutions does not exist and is not within the protection scope of the present application.

[0023] In the embodiments of the present application, please refer to Figures 1-4 As shown, according to the first aspect of the present application, a handle quick-installation structure is provided, mainly including: a handle base 1, a rocker 2 is installed on the handle base 1, a positioning sleeve 3 is arranged in the handle base 1, a positioning hole 4 is opened in the diameter direction of the positioning sleeve 3, and a steel ball 5 is placed in the positioning hole 4; a movable driving component 6 is arranged in the positioning sleeve 3, the driving component 6 is provided with a tapered structure section, the tapered structure section abuts against the steel ball 5, and by changing the position of the driving component 6 relative to the positioning sleeve 3, the tapered structure section drives the steel ball 5 to be placed inside or protrude from the positioning sleeve 3.

[0024] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0025] As Figure 2 shown, the handle base 1 is provided with an axle hole 7, the positioning sleeve 3 is fixedly installed in the axle hole 7, the positioning sleeve 3 is provided with a through hole 8 along its axial direction for providing support and positioning, and the driving component 6 is placed in the through hole 8 to move.

[0026] Furthermore, the driving component 6 includes a positioning pin 601 and an unlock button 602 which are combined with each other. By pressing the unlock button 602, the positioning pin 601 can be driven to slide in the through hole.

[0027] Specifically, the positioning pin 601 includes a connecting shaft and the conical structure section. The connecting shaft is used for connecting with the unlocking button 602, and the conical structure section is used for fitting with the inner wall of the through hole. At the same time, when the unlocking button 602 is pressed, it is ensured that the positioning pin 601 can gradually disengage from the inner wall of the through hole, allowing the steel ball 5 to slowly fall into the bottom of the positioning sleeve 3 under the action of gravity. The unlocking button 602 includes a plugging hole 9 for cooperating with the connecting shaft.

[0028] Further, a spring 10 is sleeved on the unlocking button 602. The spring 10 is placed inside the positioning sleeve 3 and abuts against the first step 11 on the positioning sleeve 3 and the second step 12 on the unlocking button 602 respectively. The spring 10 is used to drive the unlocking button 602 to return to its original position after being released. A third step 13 for restricting the maximum movement range of the second step 12 is also provided on the positioning sleeve 3. The second step 12 on the unlocking button 602 can be pressed at most to the third step 13. At the same time, after pressing the unlocking button 602 and then releasing it, the unlocking button 602 can be reset under the action of the spring 10.

[0029] Further, the through hole 8 of the positioning sleeve 3 includes an inclined surface matching section. The inclined surface matching section has a taper substantially the same as that of the conical structure section, and the two are in mutual fit, and they can be disengaged by sliding the positioning pin 601.

[0030] Specifically, the mouth of the positioning hole 4 is smaller than the maximum diameter of the steel ball 5 to prevent the steel ball 5 from completely coming out of the positioning sleeve 3.

[0031] As Figure 3 shown, a plurality of annularly and evenly distributed mounting holes are provided on the handle base 1 for mounting the rocker 2. A handle ball is mounted at the end of the rocker 2.

[0032] As Figure 4 shown, according to the second aspect of the present application, a desktop engineering drill is further provided, which includes a vertical guide rail 14 and a base 15 movable on the vertical guide rail 14. A drive shaft 16 is arranged inside the base 15. At least one end of the drive shaft 16 extends to the outside of the base 15. A socket 17 is provided at the end of the drive shaft 16, and a limiting groove 18 is provided at the socket 17. The socket 17 is used for mating with the handle quick-installation structure described in any one of the above first aspects. The positioning sleeve 3 is inserted into the socket 17, and the steel ball 5 protruding from the positioning sleeve 3 is clamped in the limiting groove 18, so that the drive shaft 16 is kept combined with the handle quick-installation structure. Rotating the rocker 2 can make the drive shaft 16 rotate, and further drive the base 15 to move up and down on the vertical guide rail 14.

[0033] Specifically, the cross-section of the end portion of the drive shaft 16 is non-circular. The handle base 1 at least partially wraps the end portion of the drive shaft 16. The drive shaft 16 can be driven to rotate through the handle base 1. The limiting groove 18 is annularly arranged in the socket 17, facilitating blind insertion of the quick-connection structure.

[0034] Furthermore, both ends of the drive shaft 16 extend to the outside of the base 15. The handle quick-attachment structure can be selectively combined with the drive shaft 16 on either side. Users can more conveniently install the handle quick-attachment structure on the drive shaft 16 at either end, which also facilitates people with different usage habits.

[0035] During use, simply press the unlocking button 602, thereby driving the positioning pin 601 to slide in the through-hole 8. The tapered section of the positioning pin 601 disengages from the inclined surface mating section of the through-hole 8. The steel ball 5 further slides downward under the action of gravity into the positioning hole 4, inserts into the quick-connection structure section, and enables the positioning sleeve 3 to enter the bottom of the socket 17. At this time, the limiting groove 18 and the positioning hole 4 are in the same position. After releasing the locking button, under the action of the spring 10, the unlocking button 602 drives the positioning pin 601 to reset. The steel ball 5 slides upward in the positioning hole 4, partially protrudes from the positioning hole 4, and cooperates with the limiting groove 18 to lock the quick-connection structure, achieving quick connection. Similarly, the quick-connection structure can be pulled out after release.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
