Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, the drill chuck includes a drill body 10, jaws 20 and a sleeve body assembly, the jaws 20 are arranged on the drill body 10, the sleeve body assembly is sleeved outside the drill body 10, and the sleeve body assembly includes a front sleeve 30, a rear sleeve 40. Connecting sleeve 50 and limiting structure 60. Wherein, the rear cover 40 is disposed on the front cover 30 and is located on a side of the front cover 30 away from the jaws 20 . The connecting sleeve 50 is sleeved outside the front sleeve 30 and can move along the axial direction of the front sleeve 30 . The limiting structure 60 is used to limit and stop the connecting sleeve 50 .

[0035] Applying the technical solution of this embodiment, when the worker assembles the drill chuck and the drill bit, the worker operates the connecting sleeve 50 to move the connecting sleeve 50 along the axial direction of the front sleeve 30, thereby making the sleeve assembly The ov...

Embodiment 2

[0051] The difference between the drill chuck in the second embodiment and the first embodiment is that the setting position of the connecting sleeve 50 is different.

[0052] Such as Figure 8 to Figure 11 As shown, the drill chuck includes a drill body 10, jaws 20 and a sleeve body assembly, the jaws 20 are arranged on the drill body 10, the sleeve body assembly is sleeved outside the drill body 10, and the sleeve body assembly includes a front sleeve 30, a rear sleeve 40. Connecting sleeve 50 and limiting structure 60. Wherein, the rear cover 40 is disposed on the front cover 30 and is located on a side of the front cover 30 away from the jaws 20 . The connecting sleeve 50 is sleeved outside the rear sleeve 40 and can move along the axial direction of the rear sleeve 40 . The limiting structure 60 is used to limit and stop the connecting sleeve 50 .

[0053] Specifically, during the process of assembling the drill chuck and the drill bit, the worker operates the connecti...

Embodiment 3

[0061] The difference between the drill chuck in the third embodiment and the first embodiment lies in the difference in the number and installation positions of the connecting sleeves 50 .

[0062] In this embodiment, the drill chuck includes a drill body, jaws and a sleeve body assembly, the jaws are arranged on the drill body, the sleeve body assembly is sleeved outside the drill body, and the sleeve body assembly includes a front sleeve, a rear sleeve, a connecting sleeve and limit structure. Wherein, the rear cover is arranged on the front cover and is located on the side of the front cover away from the jaws. One connecting sleeve is set outside the front sleeve and can move along the axial direction of the front sleeve, and the other connecting sleeve is set outside the rear sleeve and can move along the axial direction of the rear sleeve. The limit structure is used to limit and stop the connecting sleeve.

[0063] Specifically, during the process of assembling the d...

Abstract

The invention provides a drill chuck and an electric drill with the same. The drill chuck comprises a drill body, a clamping jaw and a sleeve body assembly, wherein the clamping jaw is arranged on thedrill body, the sleeve body assembly sleeves outside the drill body, and the sleeve body assembly comprises a front sleeve, a rear sleeve arranged on the front sleeve and located at one side away from the clamping jaw, of the front sleeve, one or two connection sleeves, and a limit structure used for carrying out limit stopping on the connection sleeve; in the case of one connection sleeve, the connection sleeve sleeves outside the front sleeve or the rear sleeve and is capable of moving in the axial direction of the front sleeve or the rear sleeve; and in the case of two connection sleeves,one connection sleeve sleeves outside the front sleeve and is capable of moving in the axial direction of the front sleeve, and the other connection sleeve sleeves outside the rear sleeve and is capable of moving in the axial direction of the rear sleeve. The drill chuck and the electric drill with the same effectively solve the problem of influence on assembling for the drill chuck and a drill bit, which is caused due to inconvenient holding of working personnel for the drill chuck, in the prior art.

Description

technical field [0001] The invention relates to the technical field of electric drills, in particular to a drill chuck and an electric drill with the same. Background technique [0002] At present, with the continuous miniaturization of the drill chuck, the shell of the drill chuck is shortened accordingly. However, for the staff, during the assembly process of the drill chuck and the drill bit, the shortening of the shell easily leads to a reduction in the gripping area for the staff to hold the drill chuck, which is inconvenient to hold and affects the assembly of the drill chuck and the drill bit . Contents of the invention [0003] The main purpose of the present invention is to provide a drill chuck and an electric drill with it, so as to solve the problem in the prior art that it is inconvenient for workers to hold the drill chuck and affect the assembly of the drill chuck and the drill bit. [0004] In order to achieve the above object, according to one aspect of ...
