It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0032] The following is combined with Figure 1-7 The specific implementation methods of this application are further described.

[0033] exist Figure 1 The assembly structure of the pistol drill 1 and the drill chuck 2 in the following embodiment is exemplified. The output of the pistol drill 1 outputs the rotational power, and the end of the output shaft 11 can be inserted into the drill chuck 2. The drill chuck 2 can quickly lock the output shaft 11, so that the output shaft 11 rotates and the drill chuck 2 rotates synchronously.

[0034] Embodiment 1:

[0035] The present application embodiment discloses a multifunctional assembly for quickly installing a drill chuck tool, referring to Figure 2 As shown, it includes an output shaft 11 of a pistol electric drill 1, and a drill chuck 2 that can be detachably and quickly installed on the output shaft 11; it also includes an angler 3, one end of the angler 3 is for assembling the output shaft 11, and the other end of the angler 3 is for assembling the drill chuck 2, and the angler 3 converts the driving direction of the output shaft 11 by 90 degrees for output.

[0036] Specifically, the angler 3 includes an angle housing 31, a first bearing 32, a bevel gear main shaft 33, a bevel gear slave shaft 34, and a second bearing 35. The bevel gear main shaft 33 is rotatably mounted in the horizontal direction of the angle housing 31 through the first bearing 32, and the bevel gear slave shaft 34 is rotatably mounted in the vertical direction of the angle housing 31 with the second bearing 35. The bevel gear main shaft 33 and the bevel gear slave shaft 34 are meshed and transmitted with their axes perpendicular. In order to make the rotational installation of the bevel gear main shaft 33 and the bevel gear slave shaft 34 more stable, multiple bearings can be assembled thereon.

[0037] In this solution, a quick-install lock structure 4 is provided at a portion of the corner housing 31 close to the bevel gear main shaft 33. The quick-install lock structure 4 includes an inner ring 41, a ball 42, a first spring 43, a movable sleeve 44, and a fixed ring 45. A slot 46 for inserting the output shaft 11 is provided at one end of the bevel gear main shaft 33, and a through hole 47 for partial entry and exit of the ball 42 is provided on the side wall of the slot 46. The inner ring 41 is provided with an annular groove 411 for the ball 42 to enter and exit. The end face of the inner ring 41 abuts against the corner housing 31 through the first spring 43. The movable sleeve 44 is sleeved on the inner ring 41 and is used to push the inner ring 41 to compress the first spring 43 so that the ball 42 can easily enter the annular groove 411. The fixed ring 45 is fixed to the end of the corner housing 31 to limit the movable sleeve 44. The fixing ring 45 is fixed to the corner housing 31 by screws, so that the movable sleeve 44 can be prevented from being disengaged, and the movable sleeve 44 can be limited. The movable sleeve 44 can slide to compress the first spring 43. The specific operation is: the movable sleeve 44 is moved along the axial direction, and the movable sleeve 44 simultaneously pushes the inner ring 41 to move in the same direction, and the first spring 43 is compressed by the inner ring 41. At this time, the annular groove 411 on the inner ring 41 is opposite to the through hole 47, and the ball 42 can enter the annular groove 411, so that the ball 42 will not be stuck to the output shaft 11 of the pistol electric drill 1, so that it can be disassembled. On the contrary, when the output shaft 11 is inserted into the slot 46, the first spring 43 is reset, so that the inner ring 41 and the movable sleeve 44 are reset, so that the ball 42 is pushed out of the through hole 47 by the inner ring 41 to be stuck to the output shaft 11, thereby realizing the locking assembly.

[0038] exist Figure 2 As can be seen in the figure, the bevel gear shaft 34 is mounted in the corner housing 31 through the roller column 5 sleeve. The function of the roller column 5 is to make the bevel gear shaft 34 work more smoothly and to support the bevel gear shaft 34 at both ends for rotation.

[0039] It can be seen that a 90° conversion of the driving direction of the output shaft 11 is achieved.

[0040] Embodiment 2:

[0041] refer to Figure 3As shown, an offset device 6 is added. One end of the offset device 6 is for the output shaft 11 to be assembled, and the other end of the offset device 6 is for the screwdriver or drill chuck 2 to be assembled. The offset device 6 shifts the driving direction of the output shaft 11 in parallel for output.

[0042] Specifically, the biasing device 6 includes a biasing housing 61, a gear main shaft 62, an intermediate gear shaft 63, and a gear slave shaft 64. The gear main shaft 62, the intermediate gear shaft 63, and the gear slave shaft 64 are rotatably mounted in the biasing housing 61 through bearings and mesh with each other in sequence. It can be seen that in this solution, the pistol drill 1 realizes another change of the driving position through the biasing device 6.

[0043] Furthermore, a slot 46 for inserting a screwdriver is provided on the gear shaft 64, and a tool quick-install structure 7 is provided on the upper end of the gear shaft 64. The tool quick-install structure 7 includes a through hole 47 provided on the peripheral wall of the slot 46, a ball 42, a movable sleeve 44, a second spring 71, and a retaining spring 72. A portion of the ball 42 enters and exits the through hole 47. The movable sleeve 44 is sleeved on the gear shaft 64 and one end abuts against the gear shaft 64. The outer end of the gear shaft 64 limits the second spring 71 through the retaining spring 72. One end of the second spring 71 abuts against the retaining spring 72 and the other end abuts against the inside of the movable sleeve 44. When the movable sleeve 44 pushes and compresses the spring, the ball 42 can be retracted into the through hole 47. When the spring resets and pushes the movable sleeve 44, the ball 42 is abutted by the side wall of the movable sleeve 44 to extend out of the through hole 47.

[0044] It can be seen from this that we can assemble a hexagonal tool knife (screwdriver) in the slot 46 to achieve the driving of some tool knives.

[0045] Embodiment three:

[0046] refer to Figure 4 , based on the above embodiment: a quick-clamp converter 8 is also provided.
